Integrated inertial measurement unit stabilises autonomous vehicle robots

Mon, Apr 17, 2023

The IMU330RA is an integrated inertial measurement unit (IMU) developed by Aceinna. It has high accuracy and low latency characteristics, delivering one degree per hour bias instability and 0.1 degrees per square root angular random walk. As such it provide localisation and safety for autonomous vehicles, self-driving taxis and delivery vehicles and advanced driver assistance systems (ADAS), said the company.

The IMU330RA is a six DoF (degrees of freedom) inertial sensor packaged in a ruggedised, sealed over-moulded plastic housing, sealed to IP69K level. It features a redundant three-axis accelerometer and three-axis rate gyroscope sensors for accuracy and reliability, said Aceinna.

The module supports both 1000Base-T1 automotive Ethernet and CAN-FD interfaces and provides up to 1000Hz update rate with low latency. The IMU330RA is an automotive grade, ASIL B-certified device which serves as the basis for customer positioning system integration to ASIL D, advised Aceinna.

It is designed for use in Automotive Level 3 and higher ADAS, confirmed Teoman Ustun, vice president of Aceinna’s automotive business unit. “This new sensor module provides encrypted data, at up to 1000Hz output rate over both Ethernet and CAN-FD interfaces, and supports precise synchronisation based on gPTP 802.1AS:2020 and unified diagnostic services.”

The operating temperature range is -40 to +105 degrees C. The IMU benefits from encrypted software updates and communication, with an on board hardware security module (HSM).

IMUs work together with a variety of perception sensors (for example, lidar, cameras, radar, odometry) to ensure that a vehicle stays on the correct path. If, however, the perception sensors fail because of location or environmental challenges (such as heavy rain, snow, dust, or smoke) the IMU can keep the vehicle on its projected path until data from the perception sensors re-engages or the vehicle is safely brought to a stop.

Aceinna is headquartered in Tewksbury, Massachusetts, USA. The company provides edge MEMS-based sensing solutions designed to help customers improve the reliability, cost, features and performance of end products and equipment.

The company has manufacturing facilities in Wuxi, China, and R & D facilities in San Jose California, Andover Massachusetts and Chicago Illinois, USA.

Chipset for 5G mobile devices is latest member of Semtech PerSe family

Fri, Apr 14, 2023

Semtech has expanded its PerSe product portfolio with the PerSe Connect SX9376 IC which is purpose built for 5G mobile devices.

Semtech’s PerSe technology senses human proximity and enables end devices such as smartphones to implement radio frequency (RF) control. The PerSe Connect SX9376 enables designers to optimise RF performance, enhance connectivity and support elevated compliance with global specific absorption rate (SAR) standards for 5G-enabled consumer devices.

Semtech’s PerSe intelligent sensors are used in the connected device market. They enable automatic adjustment of system level RF emissions in connected devices such as smartphones, tablets, hotspots and laptops for them to operate at peak performance while maintaining compliance, explained Semtech.

By 2030, the global 5G market is expected to grow at a 47.6 per cent compound annual growth rate (CAGR) with a market valuation of $198.44 billion. To bring these 5G-enabled products to market, OEMs must add more RF antennas into the design to address the frequency increase. The additional antennas can make it challenging for OEMs to address global SAR compliance and accurately manage the device’s RF power, explained Semtech. The SX9376 has a maximum of eight sensor inputs to support multiple antennas and simplify the sensor design without compromising performance and regulation. The chipset is also compatible with various antenna designs, making it easy to integrate into the latest 5G mobile devices, explained Semtech.

Semtech PerSe Connect 9376’s sensing performance is enabled by a high-resolution analogue front end (AFE) down to 0.74aF. It can support antenna designs with up to 600pF capacitance and is robust with advanced temperature correction to minimise false triggers caused by noise and temperature.
