AMS AS7000 Biosensor is Designed for Strapless Optical Heart Rate Monitors

Heart rate monitors (HRM) with chest straps are now being replaced by more comfortable strapless HRM, such as UWatch UX. These products are enabled by photoelectric sensors that sample light modulated by blood vessels, which expand and contract as blood pulses through them. One of such solutions is the recently introduced AMS AS7000 including a Cortex M0 core, and a DSP implementing algorithm to process raw photoplethysmography (PPG) readings from the sensors to convert them into digital HRM and HRV (Heart Rate Variability) values. Highlights of AS7000 Biosensor: MCU – ARM Cortex M0 with 4KB RAM, 32 KB EEPROM I/Os – 9 GPIOs, UART, SPI, I2C Analog electrical and optical Frontends Hardware sequencer Synchronous detector Integrated LEd driver with current control Optical filters Supply Voltage – 2.6 – 3.6V Temperature Range –30 to 70°C Package – 18 pins AS7000 can deliver greater accuracy when it is paired with an external […]

$55 UWatch UX Strapless Heart Rate Monitor Watch Syncs with iOS and Android Devices

Last time I checked about heart rate monitor, they required a chest strap to monitor ones heart rate, which I found cumbersome. It’s been while though, and I’ve now been informed that a low cost Bluetooth strapless heart rate monitor watch was available for $59.99 on GeekBuying. This type of product should provide a much more accurate evaluation of your daily calories burn rate than typical fitness bands based on an accelerometer and gyro sensor, but I’m not quite sure how they compare to the old models with a chest strap.

FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]
