Write in 65 or reply online LUMINESCENCE DETECTORS Compact LD[micro] luminescence detectors can read UV markings, labels, or guides on highly reflective surfaces such as metal, mirrors, ceramics, and polished wood. The units verify seals and bonds in packaging and medical assemblies, provide presence and position sensing, enhance quality control, and perform part counting and product identification.
Rapid 250 [micro]sec response times make them suitable for highspeed applications, and a solid-state UV light source provides more than 100,000 hrs of service. The detector emits 380 nm UV light that is converted to visible light upon striking a luminescent object or mark. The reflection is detected by the unit's receiver through a special filter that "sees" only visible light produced by fluorescence, making the LD[micro] insensitive to other light sources.

Write in 151 or reply online ON-CHIP CONTROLLER High-performance color display capability is a feature of a family of highly integrated system-on-chip (SOC) solutions.
Designed for emerging color mobile, muhimedia applications, the LH79531 is a 32-bit ARM7TDMI SOC featuring an integrated programmable color LCD controller supporting up to 1024 x 768 resolution, up to 64,000 colors, and 15 gray shades, allowing direct interface to STN, CSTN, TFT, and DMTN Panels. With factors such as high integration, low-voltage operation, on-chip PLL, and low-power RISC core, the LH79531 offers the flexibility of the programmable color LCD controller to support virtually all types of monochrome and color LCDs. It also integrates the timing circuit required to drive HR-TFT displays.
In addition to the LCD controller, a host of integrated peripherals to minimize component count and optimize system performance is available. The LH79531 achieves its performance via dual bus architecture. A 32-bit wide SDRAM bus supplies data to the LCD controller from SDRAM, while the ARM7TDMI can operate independent of the 16-bit wide bus for static memory (Flash, SRAM, ROM) and peripherals.
Dynamic bus sizing allows the buses to operate also with 16-bit and 8-bit wide memory, respectively. This gives the system and software designer flexibility in defining the memory layout of the application. Low power consumption at 60 MHz performance is made possible by the programmable built-in PLL and oscillator, which generate the system and peripheral clocks from a single, low cost 32 kHz crystal.
This, plus the LH79531's static design, power management unit, and low voltage operation, permits a high ratio of performance to power consumption. The power management function allows the chip to run in a power-saving mode. Sharp Microelectronics of the Americas, Pacific Rim Blvd.

Designed for use in bulk storage tanks, process vessels, and wet wells, the devices can also be installed in a 2 in. or larger standpipe for applications with heavy agitation, surface foam, or restricted measurement space.
Proprietary Echo-Pipe software allows operators to dampen agitation, separate surface foam, and greatly reduce the measurement space. Flowline, 10500 Humboh St., Los Alamitos, CA 90720. (562) 598-3015. Write in 203 or
