    Abstract
    Bluetooth Low Energy (Bluetooth LE) is a key technology in the envisioned Internet of Things (IoT) scenario. In fact, its extremely low-power characteristics make it one of the most suitable solutions to enable wireless communications among battery powered IoT objects ubiquitously deployed in the field with the aim of building smart environments. Although Bluetooth LE specification targets a specific set of applications mainly devoted to monitoring purposes, innovative solutions can lead to the adoption of such technology in different applications, such as multimedia streaming, allowing IoT objects to exploit new functionalities. In this direction this article presents BlueVoice, an application targeted to Bluetooth LE devices to enable speech streaming services.

    In the article BlueVoice is presented by first detailing the services set extension needed to support the new envisioned multimedia service, then a description of application choices is given, followed by an evaluation of its performance in real IoT objects. Thanks to the selected speech encoding technique, connection design choices and packetization strategies, BlueVoice application requires a communication bandwidth of 64.3 kbps to transmit audio at 16 kHz in ADPCM format. BlueVoice performance has been evaluated in terms of power consumption, memory and processing requirements, showing feasibility of the developed solution in resource constrained devices, thus confirming the correct choices in the application

    design. The set of performance information obtained show that BlueVoice is a viable solution to enable speech communications in ubiquitous wireless IoT nodes based on the Bluetooth LE technology

    So we are going to have this also, good as we need it.
    It will run on software on the MCU or added to the eFPGA.

    But consider that if it becomes ubiquitous and we ramp for the IoT, it will get hardened. 
 I look forward to the day when being an investor in QUIK is pure FUN.
This am I started the thread on QUIKs new voice over BLE....

Commentary, Adjacent possible at work. One door leads to the next. Because we have the Sensory LPSD, because we are ramping big in hearables ( slots)
because we are now on the right side of Moores law we get to add bits and pieces that make the device more appealing. Kind of fun and we can do this all the time now.


Voice- QUIK made the right decision a LOOOONG time ago. What have we added to it?

AEC, barge in,
Voice Genie- sensorie IP for hearables.
and now QUIKs own Voice over BLE.


None of them alone are huge, but collectively it starts to work in our favor.

Key thing is that they are true adjacencies. QUIK is just moving down the hall of possibility a little at a time. For a small company that is so important.

Its stuff we can do. Its NOT Babbage, going up 50 for even 2 floors taking a huge risk that it will be needed. For me Facebook is the Babbage of our day....wireless thought reading R & D.....Pure Babbage 50 floors up, but they can afford to waste the time and $$. And I hope they NEVER come close. :)

  1. Expect a blog on this. With some names....

    Another trend that is driving interest for our EOS S3 is the proprietary software we recently developed that enables EOS S3 to run voice over BLE. BLE lowers the power consumption of the wireless Bluetooth interface that is used on virtually every wearable and hearable device. We are in the process of further leveraging this and our intelligent power management technology through ecosystem partnerships.

    Commentary; Use this as what the right side of Moores law allows. You incrementally add stuff that makes the product better. We added AEC, Barge in, etc. Next up is this.

    I will keep this thread short but will look at it just a little....

    STM said it like this....

    STMicroelectronics Launches Voice-Over-Bluetooth Low Energy for Wearable and Remote-Control Applications
    BlueVoice drivers and libraries simplify product development with STM32 microcontrollers, Bluetooth® Low Energy IC, and MEMS sensors
    Geneva / 10 Jun 2015

    Voice control that can make wearable technology simpler and more battery-friendly just became easier to add with software-based innovations from STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications.
    The wearables sector is taking off, with the arrival of sophisticated new products such as smart watches. Research firm IHS predicts1 the market will reach 135 million units by 2019 and sees designs becoming smarter and more sensor-rich to support advanced functions. Ease of use and extended battery life are already important points for buyers to consider, and voice control can enhance both by minimizing touchscreen usage.

    ST’s market-leading wireless ICs, microcontrollers, and MEMS2 sensors are ideal for use in wearable electronics. With the new BlueVoice software, designers get all the drivers and libraries they need to implement voice transmission over a Bluetooth® Low Energy connection in systems built around ST’s STM32 microcontrollers, BlueNRG ultra-low-power network processors, and digital MEMS microphones. All these are available in stackable development boards for easy prototyping.

    Bluetooth Low Energy also offers advantages alongside Wi-Fi and ZigBee® in Remote-Control Units (RCUs) for home-automation systems. ST’s development platform with BlueVoice software is ideal for implementing voice and gesture control using a MEMS microphone and motion sensors, to implement a more intuitive and natural user-interface.


    CommentARY; Yes this is Syeven Johnson's adjacent possible at work. So expect that it will read just about like STM item. Only we don't have the vertical other parts that they have...so maybe we will have a reference design with a MIC maker, a BLE chip guy? Notice that QUIK is capable, they did this in house, 


    Based on the STM32Cube platform, the new osxBlueVoice middleware and BlueVoiceLink software development kit (SDK) are part of the open.AUDIO licensing program, which supports designers working with ST’s MEMS digital microphones. open.AUDIO is linked to the STM32 Open Development Environment, which provides powerful support for designers using STM32 ARM® Cortex® 32-bit microcontrollers in embedded projects.

    The BlueVoiceLink SDK can be downloaded free of charge for evaluation and development at www.st.com/bluevoicelink-nb. Activation is easy using the licensing wizard tool included in the distribution package, and volume-license terms are straightforward and business-friendly for use in competitively-priced end products.

    A snip from a TI site...

    Voice over BLE
    There is no standard way of transmitting voice over BLE so a custom profile must be used. TI’s custom profile utilizes the GATT layer of the BLE5-Stack to transmit voice frames. This is known as a Voice over GATT Profile approach (VoGP).


    So this is VERY GEEKy stuff and what can be gleaned for the rest of us?

    Ecosystem partnerships?

    Our ramping slots in hearables will make people with BLE IP want to to partner with us. Nordic? Somebody else.
    QUIK has been very creative so it will be fun to read how they do Voice over BLE.

ABSTRACT
Background: Physical inactivity is an important modifiable risk factor for chronic diseases. A new wrist-worn heart rate and activity monitor has been developed for unobtrusive data collection to aid prevention and management of lifestyle-related chronic diseases by means of behavioral change programs.

Objective: The objective of the study was to evaluate the performance of total energy expenditure and resting heart rate measures of the Philips health watch. Secondary objectives included the assessment of accuracy of other output parameters of the monitor: heart rate, respiration rate at rest, step count, and activity type recognition.

Methods: A within-person comparative study was performed to assess the performance of the health watch against (medical) reference measures. Participants executed a protocol including 15 minutes of rest and various activities of daily life. A two one-sided tests approach was adopted for testing equivalence. In addition, error metrics such as mean error and mean absolute percentage error (MAPE) were calculated.

Results: A total of 29 participants (14 males; mean age 41.2, SD 14.4, years; mean weight 77.2, SD 10.2, kg; mean height 1.8, SD 0.1, m; mean body mass index 25.1, SD 3.1, kg/m2) completed the 81-minute protocol. Their mean resting heart rate in beats per minute (bpm) was 64 (SD 7.3). With a mean error of −10 (SD 38.9) kcal and a MAPE of 10% (SD 8.7%), total energy expenditure estimation of the health watch was found to be within the 15% predefined equivalence margin in reference to a portable indirect calorimeter. Resting heart rate determined during a 15-minute rest protocol was found to be within a 10% equivalence margin in reference to a wearable electrocardiogram (ECG) monitor, with a mean deviation of 0 bpm and a maximum deviation of 3 bpm. Heart rate was within 10 bpm and 10% of the ECG monitor reference for 93% of the duration of the protocol. Step count estimates were on average 21 counts lower than a waist-mounted step counter over all walking activities combined, with a MAPE of 3.5% (SD 2.4%). Resting respiration rate was on average 0.7 (SD 1.1) breaths per minute lower than the reference measurement by the spirometer embedded in the indirect calorimeter during the 15-minute rest, resulting in a MAPE of 8.3% (SD 7.0%). Activity type recognition of walking, running, cycling, or other was overall 90% accurate in reference to the activities performed.

Conclusions: The health watch can serve its medical purpose of measuring resting heart rate and total energy expenditure over time in an unobtrusive manner, thereby providing valuable data for the prevention and management of lifestyle-related chronic diseases.

I put it up to show how medical grade devices better be accurate. They will get tested, and they just have to perform or they will NOT be adopted into a health care system. So if a Tier 1 changes a sensor- good for them. So they test it with 100 people. Hopefully they do it as in this study-compare the accuracy to a gold standard. Just like this study....these devices will be tested before adopted...

  1. Thanks to Ricks q....

    Rick Neaton

    Okay. I heard you mentioned when talking about I think B to B IoT products or some of B to B use. Can you provide some additional color or examples of what this type of product would be and how it would be used?

    Brian Faith

    Yeah, definitely. So just to clarify why B to B has been to this business, there is typically two ways that our wrist worn device could get on us as consumers, one way is we go down to our consumer electronics to buy it our self which has been the historical way of buying wearable products. The other is that you could actually get the wearable product sent to you by a hospital or your insurance provider and they subsidize the majority of the cost of that, and you agree to wear it because you agree that they have being able to see how active you are for example, during the day.

    That’s one business model that’s being guided by a lot of these insurance companies because they’re trying to promote wellbeing in the employee base for companies or their general [inaudible]. Another way that you could imagine as going to market is that you have some condition and you’re in a hospital and you’re going through treatment and the doctor would like to understand more about you and your activity, maybe your heart rate as you go through your treatment process away from the hospital. And having his wearable devices allows them to do that, not necessarily it’s something you would go buy and go to Best Buy to buy but something that you would be dictated to wear by your doctor.



    So that’s what we mean by B to B. And we’re seeing a lot of interest in that because having a sense of more wellbeing about us is a really good input for the doctor to modulate what they’re prescribing for you to do, and just get a sense of your activity. So, the analogy we give, the car insurance companies today they’ll give you a lower rate if you take that little dongle and stick it in your car, same thing with insurance for people.

    Rick Neaton

    Right.

    Brian Faith

    You wear this one thing, they’ll subsidize some of your insurance as long as you’re open to wearing the technology.

    Rick Neaton

    Do you have any estimates of the size of this particular market in terms of dollar volume as it stands within the entire wearable or hearable market?

    Brian Faith

    I don’t have a figure in front of me Rick, but I know just some of the volumes that these people are quoting, it’s definitely in the tens of millions because of all the people that are out there that are being insured. One characteristic I’d say about this market in particular, it’s probably going to be more stable and have less churn and less lumpiness than the consumer market. Consumer market is always holiday driven, or at least it tends to be. Design change every year because consumer taste changes every year. I don’t think the same thing is true for this other market.

    And it’s also worth noting that, I think there was an article published a couple of weeks ago but I think the FDA is actually listening some of the restrictions on getting products qualified through the FDA for use in these types of environment. Historically FDA was really slowdown the innovation in this area but I think they realized that if they can leverage consumer product design in this environment as long as they go to a light weight qualification with FDA, everybody benefits by that. And I think prices [ph] and acknowledgement have been market ...


    So I will track Phillips along as they are now of great interest to investors in the QUIK business.

    Philips Health Watch review

    The choice of fitness wearables on today’s consumer market is staggering. Wearables now offer a range of solutions for customers’ fitness needs making the days of food diaries quite redundant. Whilst the appetite for wearables is slowing down, the number of products on offer certainly aren’t.

    [​IMG]

    I was particularly curious about the Philips Health Watch as it has been designed as a medical device, rather than as a wearable fitness device. In fact, the decision to test it came after a conversation with Jeroen Tas, chief innovation and strategy officer at Philips. I often have trouble sleeping and Jeroen recommended the Health Watch to help me monitor my sleeping patterns.

    After receiving the Watch, which I wore for a period of around six weeks, I quickly set it up by easily syncing it with both my phone and the Philips HealthSuite app. After entering information about myself, such as weight, height and gender, the app and Health Watch were good to go.

    Upon first use the device was fairly easy to navigate, featuring a touch-sensitive dial around the watch face that you use to browse through menus and data. Information is clearly displayed, though the device’s status a health product is evident by the lack of third-party apps and software.

    The Health Watch automatically tracks your heart rate, steps and calories, and detects what types of cardio you’re doing based on walking, running or cycling. I tested out the Watch during various exercise sessions and found that it tracked my heart rate fairly accurately and was quick to detect changes in my exercise. If you’ve been stationary for too long the watch vibrates and tells you to get moving. Considering the dangers of sedentary behaviour – which has been linked with type 2 diabetes, cancer and your metabolism, the notifications are a nice reminder for you to get up and move around.

    What really lets the device down is its design, which is fairly unimposing. The Philips Health Watch features an all-black design alongside a strap that feels fairly flimsy. The upside is that the watch itself is sturdy and you don’t need to be worried if you accidentally knock it. Its unassuming design might appeal to some but it’s certainly one of the more aesthetically lacking devices on the market.

    The monochrome display is another disappointing feature of the Health Watch. Menus are easy to read but the lack of colour makes the whole display dull and uninspired. This is all to save battery life and the Health Watch does boast an impressive charge, coming in at four days. Better yet is the charger, which snaps on nicely to the back of the Health Watch and gives a full charge in under an hour.

    The HealthSuite app is also a mixed bag. Information is cleanly displayed and each health metric has a range of data that you can view. When you first open the app it asks you what health goal you’d like to achieve; whether you’d like to lose weight, get more active or simply track your habits. From there you can set calorie targets and get more insight into how healthy you are. The app uses a traffic light system across the week so you can easily check to see if you hit your targets for any particular day. Unfortunately, there are no customisation options for the app, meaning you have a plethora of menus to search through, some of which you won’t be using unless you have other Philips connected devices.

    The sleep tracking function of the Health Watch and the app is functional and informative, if not slightly limited. You need to tell the Watch when you are going to sleep and notify it when you wake up; a small annoyance as many other fitness products automatically track when you fall asleep. Even so, the Watch will you how long you slept for and the app displays the quality of your sleep with sleep stages and times in the night when you wake up. Sleep stage information is annoyingly limited to one day meaning you can’t view in detail how you’ve slept on other days.


    What is good?

    That they have been doing this for several yrs already and have probably learned a LOT on how to make it more useful the next go round?

    Our win in Europe?

    A new Phillips health watch should be at the top of our list to track along with?

    Clinical Wearables: Navigating the Next Health Technology Boom

    These are the three questions vendors need to answer during research and development for their clinical wearable to be adopted enthusiastically by hospitals, patients, and doctors.

    Wearables have undoubtedly made their mark in the health and wellness industry. With the market slated to double in size by 2021 as vendors plan to ship a total of 125.5 million wearable devices this year, according to the International Data Corporation, tracking your steps during your work day, your reps during your workouts and even analyzing your personal sleeping patterns has become the new normal. While consumer wearables have seen a monumental level of success across the board, clinical wearables have struggled to reach a similar level of notoriety until recently.

    SO notice they split wearables just as Rick has written on...consumer and CLINICAL.

    However, in the past several years we have seen healthcare professionals become increasingly vocal regarding the groundbreaking capabilities that medical wearables must offer for patients, especially in tackling the extensive monitoring needed for some of the most common chronic diseases such as COPD and diabetes. As clinical wearables continue to grow in popularity, it’s important to remember that innovation doesn’t happen in a vacuum. There are three key considerations that vendors need to make during the R&D process for these to successfully be integrated into day-to-day use in the hospital for both physicians and patients.

    What’s the End Goal?

    Connected Sensing is not something that was developed by accident—it stemmed from a growing need for a deeper understanding of patients’ needs that were failing to be acknowledged. With 44 percent of the general population surveyed in the Philips 2017 Future Health Index stating that a recommendation from a healthcare profession would be their deciding factor in adopting connected care technology such as a wearable, patients are looking to their physicians and their health systems for guidance during the digital health revolution. Medical grade


    connected sensing technologies ultimately could change the way healthcare is practiced in lower-acuity, general care areas. The process needs to be intentional and solutions need to be created with a deep understanding of not only physicians’ needs, but also patients’ previously unmet needs.


    Has the Process Been Collaborative?

    Throughout the creation process, it is important to have a collaborative relationship with everyone in hospital systems—including clinicians, executives, and patients—to make clinical wearables a reality. People in healthcare can be skeptical of new technology and its potential impact on their workflow. If clinical wearables are going to make their way mainstream, vendors need to consider the various needs and perspectives of the end user. Deploying clinical wearables on a large scale requires the vendors to deliver on the vision and functionality of the technology, while it is up to the providers, payers, and patients to share candid feedback. This type of collaborative process will help bring clinical wearables to the next level.

    Has the Technology Been Developed with the Patient in Mind?

    As physicians push for an industry-wide buy-in for clinical wearables, they will be unable to fully execute this initiative without support from patients. While these devices will collect a wide assortment of data using more sophisticated sensing, capture, and analytical functionalities, creating clinical wearables with the patient in mind is critical. Everything from size and versatility to level of comfort must be considered if vendors and physicians hope for clinical wearables to have their full potential impact.

    The healthcare industry is no stranger to the rise of emerging technologies and their potential impact as new medical devices and systems continue to be developed and brought to market on a regular basis. However, there is a specific degree of collaboration and intent that needs to be established if healthcare professionals are anticipating a clinical wearable boom of a comparable degree to their consumer counterparts. Once this occurs, we will all be witness to an industry-wide acceptance of clinical wearables technology as their capabilities become engrained in the thinking and process that clinicians utilize as they work to overcome some of the most widespread issues in healthcare. The universal adoption of clinical wearables serves as a significant component to the overall mission of connected care and brings us another step closer to improving the overall health of the population.

    Just one snip


    Vital signs tracking and patient management in the general ward

    Forty percent of unanticipated deaths occur in the general ward1. Our medical-grade wearable biosensor provides measurements for at-risk patients in low acuity settings from the ED to the general ward, care providers can assess and respond to patients whose conditions may be declining.


    Will the day come when all pts wear a medical grade wearable?


    Anyway thanks to Ricks Question we have reason to track Phillips along. They are very well suited to deliver such a device...

    For casual readers here is the snip...

    In addition to the traditional consumer use cases for wearable products, we’re also seeing more interest from companies that are addressing emerging B to B applications. OEMs that are addressing B to B applications believe there is significant volume potential as hospitals, insurance companies, fitness companies and others leverage sensor data to track activity and biometric information.

    We recently won a design with a European OEM that is addressing the B to B market with a new wearable device that utilizes our EOS S3 as the host and sensor processor and its embedded FPGA as a display driver. We expect this design will enter production during Q1 2018.

    As a mental model I am using the next Phillips health watch or a device almost exactly like it.
