 | Self-service fever scanner uses fist or wrist
FeverWarn is a new, non-contact device that determines if a user has a fever instantly -- simply by scanning the wrist or fist. The technology's creators at MachineSense, along with some university studies, say these hand areas are consistently some of the most reliable on the body for accurate temperature scanning. The FDA-compliant FeverWarn unit can be installed in front lobbies, security checkpoints, manufacturing entrances, school entrances, and any other place where the initial entryway is your first line of defense. A red or green light indicates pass or fail. Provides outputs for triggering auxiliary doors or gates.

 | Siemens introduces Simatic Micro-Drive -- the new servo-drive system for extra-low-voltage commercial and manufacturing applications
Siemens has extended its drive portfolio in the safety extra-low-voltage range for 24- to 48-V EC motors by introducing a new servo drive system named Simatic Micro-Drive. It is suited to a wide range of diverse applications such as precise positioning, shuttles for storage and retrieval machines or warehousing systems, automatic guided vehicle systems, and medical technology. Components consists of the PDC (Profidrive Control) servo drive in conjunction with a flexible range of motors and connecting cables from product partners. Simple connectivity to Simatic programmable logic controllers (PLCs) helps reduce the engineering workload significantly. Integration into Siemens automation technology via its TIA Portal makes for simple commissioning and servicing. Smart encoders and one-button tuning add to its plug-and-play startup. The system offers units from 100 W to 1 kW and allows for side-by-side rail mounting.

 | MathWorks introduces Motor Control Blockset for algorithm development
MathWorks has just released Motor Control Blockset, an add-on product for Simulink for designing and implementing motor control algorithms. Now, motor control engineers can use reference examples and Simulink blocks for developing field-oriented control algorithms to spin brushless motors. The blockset extends the set of Simulink products for motor control design, enabling engineers to test algorithms with each design change, generate fast and compact ANSI/ISO C code, and use simulation to validate software, which can reduce certification testing cycles.

 | Cadillac's giant 4-cylinder was made for truck use
Jason Fenske from Engineering Explained delves into the engineering behind GM's L3B engine, one of the largest gasoline 4-cylinders available. It features a dual volute turbocharger, advanced three-position camshaft, integrated exhaust manifold, and jumbo cylinders. You can find the 2.7L I4 engine variants in both the Chevy Colorado pickup (310 hp) and the Cadillac CT4-V four-door (325 hp). Very interesting. You always learn something from a Fenske presentation.

Optimize mechanical misalignments, get hidden benefits
C-Flex Couplings combine the best qualities of disc, beam, and bellows couplings in a unique and economical new design. Made to couple two rotating shafts together, these couplings can accommodate large misalignments while transmitting high torque loads with zero backlash. Benefits include lower energy usage and less-frequent bearing failure, since less stress is placed upon bearings. Constructed using high-strength hardened stainless steel or glass-impregnated polyamide flexures, these couplings require no maintenance and provide years of trouble-free life, even in contaminated environments. Flexible Pivot Bearings and Super Plastic Torsional Damping Couplings also available.
Watch C-Flex Couplings handle misalignments.
