 | Gears and gear racks made from polyamide
Gears and gear racks used for transmitting torque and forces within gearboxes are typically made of hardened steel. For many other uses and applications, gears and racks made from plastic are the better choice. These generally require no lubrication and are lighter, quieter, less expensive, and more resistant to corrosion than metal gears. This is why JW Winco has expanded its range with polyamide gears and racks that can transmit high forces and torques. Spur gears EN 7802 and gear racks EN 7822 are made from strong and long-lasting polyamide and are also available in gray or blue for better visual detectability.

 | Compact stepper drive offers greater smoothness, precision, torque density
Kollmorgen has just released the new P80630-SDN stepper drive. Customers can now benefit from features such as smoothness, precision, and torque across the full speed range in a significantly more compact package that enables smaller, lighter, and more versatile machines. The P80630-SDN is an ideal solution for labelers, indexing tables, CNC machines, packaging systems, pumps, and other single- or multi-axis systems requiring low-speed, point-to-point motion control for fixed loads.

 | How do autonomous vehicles see at night?
Owl Autonomous Imaging is offering a new whitepaper that explains how the Owl Thermal Ranger uses convolutional neural networks (CNNs) to accurately and reliably locate and classify pedestrians and animals in the dark from their own thermal signatures using just one infrared camera. This whitepaper covers the history of convolutional neural networks, how the technology works (AI/machine training), why Owl thinks the CNN approach is the best solution to address current pedestrian safety concerns, and how auto manufacturers can implement it. Very interesting.

 | Anti-surge resistors handle surges up to 10 KV
High-voltage applications such as HVAC controls, appliance and white goods controls, metering, automation, medical devices, digital storage, and surge-protection devices typically require resistors with high working voltage that may be challenging to find. If the applications are low current or low energy, film resistors are an ideal technology. The ASR/ASRM series from Stackpole offers high working voltages, high pulse voltage handling, and well-defined pulse behavior. For applications with high-voltage surge and low-energy requirements, the ASR/ASRM is a viable replacement for carbon composition resistors, providing improved electrical and environmental stability, better tolerance and TCR, with better long-term availability.

 | Toroidal propeller: More speed, fuel savings claimed
Is a toroidal propeller the next big thing in boating? Sharrow Marine, creator of the Sharrow Propeller, thinks so. Four years of independent and factory testing have proven this design bests standard blade technology by providing: significant speed increase at mid-range RPMs, up to 30% greater fuel efficiency, less vibration, dramatic noise reduction, more reverse thrust, superior handling in tight turns at high speeds, and more. The Sharrow Propeller has won numerous innovation awards from both boat shows and highly respected marine publications.
