Bluetooth 5 Radio for Connected Health Devices
ON Semiconductor’s RSL10 multi-protocol Bluetooth 5 certified radio System-on-Chip is
capable of supporting the advanced wireless functionalities emerging in the IoT and Connected Health & Wellness sectors without compromising battery life or overall system size.
Target applications for this device include wearables such as fitness trackers, smart watches
and wearable medical devices.
The RSL10 supports the Bluetooth low energy standard’s higher data rates while optimizing
power consumption for applications using 1.2 and 1.5 V batteries. Its dual-core architecture is based on a user-programmable ARM Cortex-M3 processor, which provides clocking
speeds up to 48 MHz and the flexibility to support 2. 4 GHz proprietary wireless protocol
stacks. Also featured is an ultra-low-power 32-bit Dual-Harvard Digital Signal Processing
(DSP) system, for signal processing applications such as wireless audio codecs.
Weirless Radial Diaphragm Valves
ASEPCO Weirless Radial diaphragm valves from Watson-Marlow are easy to seal, inspect and
never need retightening or adjustment. The valves are contamination-free and feature a 180°
flow path, with superior drainability in multiple orientations without leakage. The valves feature
high-end actuators with numerous options, including a control interface that enables users
to use the weirless valve to control flow in process lines. Machined from solid 316L stainless
steel (other materials are available, such as, AL6XN or Hastelloy) each valve is serialized and
laser-etched for full traceability. The valves meet ASME BPVC, ASME BPE and CE-PED standards.
Infrared LED for Iris Scanners
The SFH 4787S infrared LED (IRED) from Osram Opto for iris scanners illuminates the eyes evenly. Like its
predecessor (SFH 4786S), its direction of emission is slightly angled rather than vertical, thus simplifying the
design process by eliminating the usual mechanical aids. A wavelength of 810 nanometers (nm) delivers
high-contrast images for all eye colors. The emission direction is tilted by 8°, while the emission angle is ± 18°.
The optical output of this highly efficient emitter is 720 milliwatts (m W) at a current of 1 amp, with a radiant
intensity of 1,000 milliwatts per steradian (mW/sr).
The SmartBond 5.0 DA14580, a small, low power, and Bluetooth SoC from Dialog Semiconductor is used for adding Bluetooth low energy to products like remote controls, proximity
tags, beacons, connected medical devices, and smart home nodes. It supports all Bluetooth
developments up to and including Bluetooth 5 and Bluetooth low energy Mesh. It features 2
Mb of Flash memory and 96 kB of RAM. It also has double the memory for user applications
of its predecessor and an integrated microphone interface for voice support at low additional
3-in- 2 Memory Card Connectors
The 3-in- 2 card connector from TE Connectivity (TE), is designed for enabling SIM and micro
SD card connectivity in ultraportable devices. This card connector’s space-efficient design features two cavities with the flexibility to accept either two SIM cards or one SIM card and one
micro SD card. It saves about 20 percent PCB space over other combination-type card connectors. TE’s new 3-in- 2 card connector uses an anti-buckling contact design, which prevents
damage to cards during insertion and removal, for more robust connections than those provided by competitive products. Its space-efficient design incorporates a push-pin type solution
with a mechanical lock function. Additionally, better coplanarity control across the connector
helps ensure fewer defects and easier soldering during the manufacturing process.
