Smaller personal electronics, enterprise, industrial and communications designs can be achieved with the INA185 current-sense amplifier, and open-drain TLV4021 and push-pull TLV4041 comparators, claims Texas Instruments.

Integrated MEMS inertial module up their game
Designed for augmented reality (AR), virtual reality (VR) and tracking applications, STMicroelectronics has designed the LSM6DSR inertial module for next-generation gaming, industrial, and sports applications.
STMicroelectronics improves GUI for custom motion-sensing design
To simplify the configuration of the finite state machine and machine learning core (FSM and MLC) logic of STMicroelectronics’ inertial measurement units (IMU), including the recently announced LSM6DSO and LSM6DSOX six-axis modules, STMicroelectronics has introduced the Unico GUI (STSW-MKI109L for Linux, STSW-MKI109M for Mac OSX, and STSW-MKI109W for Windows machines.
FSM logic lets users run gesture and motion-recognition algorithms directly in the sensor for always-on convenience and low power consumption. The MLC implements machine-learning classifiers for real-time always-on motion and vibration pattern recognition.
Using Unico GUI to configure the module’s internal registers and embedded FSM and MLC logic, users can quickly and easily create their own motion-recognition algorithms, explains ST. The GUI also eases combining the module’s accelerometer and gyroscope data with inputs from additional external sensors, such as a magnetometer, for sophisticated context-sensing capabilities.
FSM and MLC in smartphones, wearables, or industrial devices operate as an embedded, low-power engine for gesture and motion recognition and allow user-interface functions and context-aware apps to continue running while the main processor sleeps to maximise battery runtime.
The LSM6DSO six-axis module contains logic for up to 16 independent state machines, each generating a hardware interrupt activated by a specific motion pattern, while the LSM6DSOX contains also the logic to implement multiple-stage decision trees for machine-learning classification.

LED driver sheds light on animation effects
Smooth animation effects in wearable electronics and appliances – where the light fades in and fades or dims in increments (known as colour chasing or deep breathing) – can be achieved using STMicroelectronics LED1202 12-channel LED driver. The programmable 12-channel RGB-LED driver is designed to enhance lighting effects and animation for smart devices around the home and wearable electronics.
