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 […]

LG Rolly is a Bluetooth Keyboard that Folds into a Stick

There are already some flexible Bluetooth keyboards that you can roll into your bag or pocket after being done typing on your smartphone or tablet, but LG is about to launch Rolly Keyboard, a solid Bluetooth keyboard for mobile device that can be rolled into a stick, which should may be sturdier than flexible keyboards, and it can also hold a smartphone or tablet in upright position with a display of up to 10″ in size. LG’ latest keyboard (model KBB-700) is comprised of 17mm keys – a standard keyboard comes with 18mm keys – arranged into four rows, that can be folded into a stick as shown above. The company also claims the keyboard offers “satisfying tactile feedback not found on flexible silicone keyboards”.

Tronfy MXIV Telos TV Box Review with Android 5.1

Tronfy MXIV Telos is a TV box powered by Amlogic S812 processor running Android 5.1 Lollipop and costing just above $90 (with coupon), so it will be interesting to find out how it performs compared to Mygica ATV1900AC also based on Amlogic S812 SoC, and Android Lollipop firmware (version 5.0.2), which I reviewed recently, and sells for $169. I’ve already checked the hardware in Tronfy MX4 Telos Unboxing and Teardown, so today I’ll check how the device actually performs. First Boot, Settings and First Impressions I started by connecting peripherals: A USB hard drive to one of the USB port, and a USB hub to the other USB port with a webcam, and two RF dongles for an air mouse and a wireless gamepad, as well as HDMI and Ethernet cables, and the power supply. I then had to press the power button on the unit to start it up, […]
