Priced for consumer market, IMU is accurate and efficient, says Bosch

Mon, Oct 24, 2022

Priced for cost-sensitive consumer applications, the cost-effective BMI323 motion sensor inertial measurement unit (IMU) has been announced by Bosch Sensortec. It is designed with integrated features for a shorter development time.

The BMI323 is suitable for standard consumer products, such as toys, gaming controllers, remote controls, wearables, fitness trackers, smart watches, tablets and laptops.

The general-purpose, low power IMU combines acceleration and angular rate (gyroscopic) measurement with intelligent features that are triggered by motion. These make development faster and easier for OEMs, claimed Bosch Sensortec. For example, the BMI323 already includes Bosch Sensortec’s step counter software, so customers do not need to spend time developing their own algorithms. Other features include motion detection that can turn sub-systems on or off when a device, such as a TV remote control, is put down or picked up, to reduce overall power consumption.

Bosch Sensortec has improved accelerometer performance compared to the earlier BMI160 IMU and has also lowered power consumption. In high-performance mode, using both the gyroscope and the accelerometer, the BMI323 has a current consumption of 790 microA compared to 925 microA on the BMI160. This represents a reduction of nearly 15 per cent.

The six-axis BMI323 has a self-calibrating 16-bit triaxial gyroscope, a 16-bit triaxial accelerometer, and a 16-bit digital temperature sensor housed in a miniature 2.5 x 3.0 x 0.83mm³ (14-pin) LGA package. This is pin to pin compatible with the BMI160.

The BMI323 is the first IMU device announced by Bosch Sensortec to include the new I3C interface, in addition to the SPI and I2C interfaces.

The IMU is available now.

Invicta antenna extends Bluetooth, Wi-Fi and ZigBee coverage, says Antenova

Thu, Oct 13, 2022

Antenna and RF antenna modue manufacturer, Antenova, has released the Invicta compact antenna. It is for use with Wi-Fi, Bluetooth and ZigBee frequencies at 2.4 to 2.5GHz and averages 70 per cent efficiency across the 2.4GHz band.

The Invicta antenna averages efficiency of 70% across the 2.4 GHz band. Using this antenna allows designs to operate over longer distances and through walls and obstacles, said Antenova, extending the coverage and performance of wireless devices using Bluetooth, Wi-Fi and ZigBee.

It is a flexible printed circuit (FPC) antenna, which is easy to place in a design. It connects directly to the PCB via a cable and IPX MHF (UFL) connector. The antenna comes with 100mm cable as standard; other cable lengths and connector options are available on request.

An FPC antenna is different to an SMD antenna in that it operates independently to a ground plane length and no antenna matching is required, so the design cycle for Invicta is simpler and shorter, said Antenova.

The FPC antenna also makes for easier manufacturing, as the antenna is fixed in place by a simple self-adhesive strip. It can be curved and inserted into the case of a design. This style of antenna is suited to small to medium volume manufacturing.

Antenova has designed the Invicta antenna primarily for smart battery-powered devices for the home and office, where one single device provides global coverage. Typical applications in the home would be smart meters, home automation, wireless sensor networks, smoke and intruder alarms. It would also be used for remote monitoring in industrial and medical environments.

“The efficiency of an antenna is related to its size, with larger antennas usually providing better performance. The Invicta antenna . . . performs better than PCB trace antennas and provides exceptional performance and range in return for the relatively small space in a design,” said Antenova’s product marketing manager, Michael Castle.

The Invicta antenna part number is SRFW082.

2K2K square resolution CMOS image sensor maximises vertical coverage

Wed, Oct 12, 2022

For security wide-field of view and AR / VR / MR pass-through cameras, Omnivision’s first 2K2K (2048 x 2048) square resolution CMOS image sensor introduces features to the industry. The OS04E10 is claimed to be the industry’s first image sensor with digital watermarking, a built-in anti-spoofing feature that ensures no tampering with the original video source takes place.

The 2.0 micron pixel image sensor is designed for 1:1 aspect ratio security systems to maximise vertical coverage in security wide-field of view (dome, fisheye, and doorbell) cameras as well as pass-through (AR / VR / MR) cameras. The sensor captures real-time fast-moving video and features always-on low power mode at 512p for pre-roll video recording capabilities.

Security has become the largest CMOS image sensor market segment after mobile and computing devices. From 2021 to 2027, according to Yole Intelligence’s Imaging for Security 2022 report, this market segment is expected to grow from $2.1 billion to $3.6 billion at a 9 per cent compound annual growth rate (CAGR).

“Pairing the OS04E10 with Omnivision’s OA7600 and OA8000 [ASICs] provides a total battery-powered camera system with always-on and pre-roll video recording capabilitie,” said Devang Patel, marketing director for the IoT and emerging segment at Omnivision.

The OS04E10 image sensor has a 2.0 micron pixel with a 1/3.11-inch optical format and is based on Omnivision’s PureCelPlus technology, which is claimed to reduce pixel crosstalk and noise for better colour reproduction under low-light conditions. Its onboard Nyxel near-infrared (NIR) technology ensures low to no ambient light image capture with IR source will result in clear and crisp images. It can also provide opportunities for camera designers to extend battery life. The sensor’s two-exposure staggered HDR mode increases dynamic range. The OS04E10 supports MIPI and LVDS interfaces.

Samples of the OS04E10 are available now, and it will be in mass production in the second half of 2023.
