Reader O f f er Win one of three FiND-iT kits with RFID label tags Jointly released by the RFID Journal, Microelectronics Technology (MTI) and Enso Detego, the FiND-iT is a PC and Android smartphone or tablet solution that enables users to associate passive ultrahigh-frequency (UHF) radio frequency identification tags with items, as well as create inventory lists and find those objects using an Android smartphone or tablet. This month, Enso Detego gives away three FiND-iT kits for EETimes Europe readers to win, including one MTI RFID ME USB dongle reader, one MTI MINI ME RFID reader for Android hosts, a USB 18-inch extension cable, a USB On-the-Go (OTG) Adapter cable, and 50 pre-encoded and serialized EPC Gen 2 RFID label tags. When the UHF RFID tag is presented to the PC running the FiND-iT software and equipped with MTI’s USB dongle reader, the user can enter information about that object, including its name and location, along with other attributes created by that individual. The Mini Me RFID reader can be attached to any device capable of supporting Android hosts.

The bright LED matrix has an on-board processor, allowing Raspberry Pi users to display messages and graphics by sending simple commands and text strings to the serial port. The ‘Pi-Lite’ display unit is a pre-built plug & play module, but it can also operate in stand-alone mode, and when combined with one of Ciseco’s radio modules can even form a wireless display unit. The ‘Pi-Lite’ idea comes from the very popular Arduino Lots of LEDs shield by Jimmy Rodgers and brings these capabilities to the Raspberry Pi user. The board features a 9x14 (126) red LED matrix (a white version will be available soon), an onboard Arduino ATmega 328 processor allowing each pixel to be individually addressed, and an on-board controller that can be upgraded or reprogrammed using the standard OptiBoot serial bootloader. The kit comes with Ciseco firmware that will scroll text, display bar graphs, VU meter, and address individual pixels.

The TMPM36BF10FG comes equipped with 258 kByte of SRAM and 1 MByte of ROM and is well suited for controlling complex systems that involve large software and data sets. Featuring an optimised circuit design, the TX03 series Microcontroller consumes just two thirds of the power of equivalent products, claims the manufacturer. The Microcontroller is pin-compatible with TMPM36BFYFG, which will have a lower memory capacity and is scheduled to start mass production in November 2013. Toshiba Electronics Europe www.toshiba-components.com ClearSource LED emitters enable precision sensing and detection Optoelectronics technology company OMC has introduced a range of solid-state emitters that use a new die bonding technique to connect the LED chip electronically to the leadframe, eliminating ‘dark spots’ and improving beam precision. Standard LED optical Sensors use a top-mounting wire bond to connect the LED chip to the anode or cathode. The bond wire obstructs the light output, giving rise to dark spots and patches in the beam which makes precise sensing and detection more difficult. In OMC’s new ClearSource series, the wire is bonded to the side of the chip, leaving the output beam unobstructed. This produces a defined light beam which enables high-accuracy sensing and detection. For even greater precision measurements that require near-parallel light emission, lenses can be incorporated. Additionally, this die-bond configuration reduces capacitive effects within the diode, enhancing switching speed and reliability. According to OMC, ClearSource emitters also benefit from LED technology’s inherent high reliability and long lifetime. The devices have a low sensitivity to ESD, and are suitable for a wide range of applications including encoders, Linear positioning, line and edge sensing, medical equipment, fibre optic systems, machine vision, optical switching, distance and range finding. Devices are available with standard apertures for 650nm and 850nm LEDs with ball-type narrow beam, flat, dome, or drip encapsulation lensing options.
