I finnaly found a company Knowles, who has researched if ultrasonic comm will bother our canine brothers. It looks like they are in the clear, but here is the scientific answer from those in the know at Knowles:
"Based on our acoustic expertise and informal conversations with application developers, ultrasonic signals should not be an issue or bothersome for dogs or other animals.
The intended range for ultrasonic functionality within mobile consumer electronics is less than two feet and therefore, applications would transmit very low level of ultrasound.
Additionally, the transmitted signals are noise-like (broadband) rather than a single tone. This allows the frequencies blend into the background with other acoustic frequencies.
Finally, ultrasonic signals are typically directional and they tend to require a relatively straight line of sight to be effective. This means objects such as furniture and walls will limit the potential for ultrasonic frequencies to affect animals.
Knowles encourages all application developers to operate within the safe guidelines outlined by government organizations and animal experts."
I can't tell if you are joking or not, but seriouly. I just upgraded to a iPhone 5s from a 4s for just that reason (plus they gave it to me for free with no contract). For years Apple's arguement was that you should be able to operate you phone with one hand. On the other hand, I see two advantages to a bigger screen--easier typing because those tiny keys will be slightly bigger, and the other is that some people won't have to carry a tablet and a phone.
Well I'm used to keeping my 4s in my trouser pocket ('pants' to most of you guys) - so am I going to have to get bigger trousers for the 6? Will the local Apple Store allow me to try out the 6 in my current pockets? Would be good for Apple to publish a trouser-compatibility guide, or maybe even an app, for this condundrum... :-)
Apple already announced its HealthKit API which will allow different health and fitness apps to share information that can be accessed from a central hub. Hardware-wise the M7 chip already offers a smart hub that fuses the data from the iPhone 5s' inertial sensors, which fitness apps are already accessing. Rumor has it that the M7 will be much larger in the iPhone 6 which indicates more sensor-monitoring abilities--whether they are built-in or plugged-in. Also Reuters recently claimed that the HealthKit service "will work with health providers at Mount Sinai, the Cleveland Clinic and Johns Hopkins as well as with Allscripts, a competitor to electronic health records provider Epic Systems..."
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
