E-mail: rbennett@ginsbury.co.uk Phone: 0044 1634 298900 Fax: 0044 1634 290904 specifically for the demand for ever smaller LED components producing highly collimated light. Plessey’s dotLEDs weighs 0.2 mg and has a profile of 0.2 mm which makes the device an industry-leading option for any wearable application with LED content. The PLW138003 is first product in Plessey’s dotLED family and delivers up to 0.7 lm of white light with a 130 degree viewing angle from a 5 mA drive current. A blue version, the PLB138003 is also available. Further additions to the dotLED family will be colour variants and a series in the larger 1608 footprint. By using standard silicon semiconductor production techniques, Plessey is able to produce high-volume high-quality industry standard LEDs that are demanded in the consumer electronics market. Plessey Semiconductors www.plesseysemiconductors.com Flexible capacitive switch enables minimal user interfaces Molex has developed a capacitive switch technology that provides an intuitive User Interface (UI) with minimal manual controls. Based on Flexible Printed Circuit (FPC), complete with the capacitive IC and all associated components and combined with graphic overlay, metal domes and silicone rubber actuators, the capacitive switch is currently deployed on GE Healthcare’s Vscan device, a highly-portable ultrasound scanner. This solution allows the UI to be mounted externally, with the tail of the FPC to be inserted into a small opening in the top housing. This design simplifies assembly, the adhesive-backed UI can be placed anywhere on the front housing, it only leaves a small opening in the housing making it easier to dealwith EMI/EMC issues. While fully flexible in choice of capacitive controllers, for this solution Molex used Cypress Semiconductor’s CapSense PSoC chip architecture, which replaces dozens of mechanical switches and controls with an elegant touch-sensitive interface. This technology is resistant to contaminants, which makes this user interface more robust to wear and tear and reliable than its mechanical counterparts. Being sealed, it is also fit to endure sterilising solutions used in the medical environment. Molex www.molex.com RFID temperature sensor tag takes from -30 to +300ºC The Pyros-TGT2-DWB from unveiled by Farsens S.L. is an RFID sensor tag capable of transmitting a unique identifier and associated temperature measurement data to a commercial EPC C1G2 reader without the need for a battery on the sensor tag. The device features a 103GT-2 NTC thermistor (10K) from Semitec with a measurement range from -10 to +120ºC degrees with an accuracy of ±0.5ºC. The device also offers an extended temperature range from -30 to +300ºC with an accuracy of ±3ºC while the actual RFID tag operation range is -30 to +85ºC. The tag comes in a variety of antenna designs and sizes to adapt the performance to the required application in the 860-960 MHz band. The reading distance for the battery-free thermistor tag is around 1.5 meters and it can be embedded in a wide variety of materials such as plastics or concrete. It can also be encapsulated in an IP67 or IP68 casing for usage in harsh environments. Farsens S.L. www.farsens.com www.electronics-eetimes.com Electronic Engineering Times Europe April 2014 45
