`Muting' safety light screen
Minneapolis, Minn. -Micro-Screen is a safety light screen system that features a "muting" function that temporarily suspends light screen operation, allowing parts to enter and exit the protected area without shutting down guarded machinery. This action eliminates the need to shut the safety system down during part-feeding operations, saving both time and increasing throughput. Intended for a wide range of automated machine guarding operations, the device features separate diagnostics and function selection switches for mode of operation, timing features, and input/output control.

Simplify single-level, single-loop process control
Milford, N.H. - SimLink control system simplifies and reduces the cost of single-level, single-loop process control. The system provides a single dedicated field controller per process that can either be controlled from a PC, or run autonomously. Both electric and pneumatic actuators can be controlled. A variety of analog and digital inputs providing on-off and proportional control settings are available. The control program provides simple graphical control of multiple units. No programming or graphical hierarchy of any kind is required. SimPro Controls
High-bright flat-panel screen
Fremont, Calif.- PAC Series of expandable portable computers has now received what is said to be the brightest industrial flat-panel screen. PAC display boasts a display brightness of over 250 nits and a constant ratio of greater than 200 to 1. The screen is intended for mobile industrial computing applications and features a 12.1-in. active matrix TFT color display. A black matrix coating provides anti-glare/anti-reflection viewing. Backlight life is over 50,000 hr. Dolch Computer Systems Inc.
Pneumatic control system
Monee, Ill. - Pneumatic Control System (PCS) is designed to control any of the developer's pneumatic position feedback actuators. The system is a closed-loop electronic controller with pneumatic valves that can accurately position the actuator rod or shaft and hold it in position with various degrees of accuracy and force. Repeatability of linear motion applications can be as good as Bimba Manufacturing Co.
