Cool Tools: Leica RTC360 3D laser scanner -- LIDAR for big jobs

The new Leica RTC360 laser scanner available from Exact Metrology makes 3D reality capture faster than ever before. With a measuring rate of up to 2 million points per sec, colored 3D point clouds can be completed in under 2 min. Automated, targetless field registration and seamless, automated data transfer from site to office reduce time spent in the field. The CAD models are generally used for factory/shop floor layout plans, power plant equipment changeouts, proof dimensioning, and much more. In addition to the 3D model, full spherical HDR imagining is appended directly to the point cloud, giving a photo-realistic effect to the data and allowing for virtual walkthroughs of the areas, shareable markups, geo-referencing, and meta-tagging. So many uses.

Graphene Hall sensor for cryogenic applications -- including quantum computing

How futuristic is this? U.K. company Paragraf has introduced a graphene Hall sensor that enables commercial organizations to measure high magnetic field strengths accurately at cryogenic temperatures, increasing manufacturing throughput by quicker magnet mapping and replacing existing NMR probe mapping stages. The GHS-C is the only Hall sensor now in volume production that can offer this level of performance at temperatures below 3 K. It is being supplied in the industry-standard LCC 20 package, making it a drop-in replacement for existing Hall sensors. Applications include quantum computing, high-energy physics labs, cryogenic cooling equipment, fusion, medical accelerators, ultra-low-temp research, and magnet manufacturing.

What's a strain wave harmonic gearing torque sensor?

Strain wave harmonic gearing sensors from FUTEK are an alternative to six-degrees-of-freedom (DOF) sensors used in applications such as robotic arms that are used in surgery. For example, during some laparoscopic surgery procedures, surgeons must hold the position of the end effector (the instrument inside the abdominal cavity) while the robot arm is moving. This maneuver is difficult to perform with 6-DOF sensors only, because it requires torque measurement on each joint. Strain wave harmonic gearing sensors can handle it, and they are less expensive to implement because torque measurement can be obtained for selected joints only if necessary.

Raspberry Pi: Pico microcontroller

The Raspberry Pi Pico is built around the brand-new Raspberry Pi RP2040 microcontroller, delivering a flexible, highly affordable development platform that can also be directly deployed into end products -- all for 4 bucks. At the heart of the Raspberry Pi Pico is RP2040, which features two ARM Cortex-M0+ cores clocked at 133 MHz; 264 kB of on-chip SRAM; 30 multifunction GPIO pins; dedicated hardware for commonly used peripherals alongside a programmable I/O subsystem for extended peripheral support; a four-channel ADC with internal temperature sensor; and built-in USB 1.1 with host and device support. Also look for the RP2040 chip to be sold as a standalone product very, very soon.

New robust angle sensors for off-highway and more

Novotechnik, U.S. introduces the RFE 3200 Series of resilient, touchless Hall-Effect angle sensors. These sensors are specifically designed to operate in demanding environments like off-highway equipment and feature ingress protection to IP69K, EMC immunity, and a decoupled sensor/magnet. The RFE Series measures from 0 to 360 deg and can be ordered with one (partially redundant) or two (fully redundant) channels. High resolution with great dynamic response, large mechanical tolerances, and feasibility of customer-specific output options are added benefits of this wear-free technology.

"We're delivering reliable PNT where our customers need it -- from soldiers' handheld devices to small unmanned aerial vehicles," said Greg Wild, director of Navigation and Sensor Systems at BAE Systems. "MicroGRAM-M provides our armed forces and allies with a low-SWAP M-Code GPS solution that's resistant to adversaries' disruption efforts in highly contested environments."

MicroGRAM-M features rapid, secure GPS signal acquisition, enhanced security and resiliency, anti-jamming and anti-spoofing capabilities, and the industry's lowest power consumption for an M-Code device. The 1.0-in. x 1.25-in. x 0.275-in. MicroGRAM-M enables quick upgradability to M-Code and reduced system integration costs. At its core is a proven, tamper-proof M-Code Common GPS Module that encapsulates classified data and signal processing.

Companion BAE products are the MPE-M and NavStrike-M, which both deliver enhanced awareness in highly contested environments and precision munitions guidance.

"Qualification of MicroGRAM-M is underway, with full-rate production expected in 2022," said John Watkins, vice president and general manager of Precision Strike & Sensing Solutions at BAE Systems.

This division of BAE is located in Cedar Rapids, IA.
