20120086335 | EXTERIOR VEHICLE LIGHTS - A lighting system for exterior lights of an automobile comprises a first lighting unit ( | 04-12-2012 |
20120256645 | CAPACITIVE SENSOR, INTEGRATED CIRCUIT, ELECTRONIC DEVICE AND METHOD - A sensor for sensing an analyte includes capacitive elements, each having a pair of electrodes separated by a dielectric wherein the dielectric constant of the dielectric of at least one of the capacitive elements is sensitive to the analyte, the sensor further including a comparator adapted to compare a selected set of capacitive elements against a reference signal and to generate a comparison result signal, and a controller for iteratively selecting the set in response to the comparison result signal, wherein the sensor is arranged to produce a digitized output signal indicative of the sensed level of the analyte of interest. An IC comprising such a sensor, an electronic device comprising such an IC and a method of determining a level of an analyte of interest using such a sensor are also disclosed. | 10-11-2012 |
20120290241 | METHOD OF CHARACTERISING AN LED DEVICE - A method of characterising an LED, as well as an integrated circuit using this method, based on a so-called characteristic resistance, in which the LED is operated at a first, relatively low, operating current and then at a second, relatively high, operating current. From the ratio between the difference between the forward voltages at these two operating currents, and the difference between the operating current, the characteristic resistance is determined. The characteristic resistance is measured at two or more moments during the operational lifetime of the device, and a prediction or estimate is made in relation to the total operational lifetime of the devices, from the evolution or change of the characteristic resistance. | 11-15-2012 |
20130057157 | Lighting System - A lighting system uses interior and exterior light sensors for detecting lighting level and colour. A lighting unit has a controlled colour and intensity so that a colour match zone can be defined where the interior space lighting has colour temperature based on the exterior lighting conditions. | 03-07-2013 |
20130207206 | SEMICONDUCTOR DEVICE HAVING AU-CU ELECTRODES, AND METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE - A method of manufacturing a biosensor semiconductor device in which copper electrodes at a major surface of the device are modified to form Au—Cu alloy electrodes. Such modification is effected by depositing a gold layer over the device, and then thermally treating the device to promote interdiffusion between the gold and the electrode copper. Alloyed gold-copper is removed from the surface of the device, leaving the exposed electrodes. The electrodes are better compatible with further processing into a biosensor device than is the case with conventional copper electrodes, and the process windows are wider than for gold capped copper electrodes. A biosensor semiconductor device having Au—Cu alloy electrodes is also disclosed. | 08-15-2013 |
20140097849 | METHOD OF DETECTING A LED FAILURE, A CONTROLLER THEREFOR, A LIGHTING UNIT AND LIGHTING SYSTEM - Disclosed herein is a method of detecting an LED failure in a series-connected string of LEDs using a parameter indicative of a voltage difference between a voltage across the string at a predetermined relatively high current and a voltage across the string at a predetermined relatively low current. The disclosure extends to controllers configured to detect an LED failure in a string of LEDs, to LED lighting units comprising such controllers, and to lighting subsystems, for instance automobile lighting subsystems. | 04-10-2014 |
20140151221 | BIOSENSOR MODULE COMPRISING A BIOCOMPATIBLE ELECTRODE - A method of manufacturing a module for a biosensor is disclosed. The method includes providing a substrate. The substrate includes a trench and a bond pad. The trench is filled with an electrically conductive material and the bond pad is arranged within the substrate. The method also includes removing a part of the electrically conductive material from the trench such that a recess is formed in a surface of the substrate, forming a biocompatible electrode in the recess, and removing a part of the substrate such that the bond pad is accessible through the surface of the substrate. | 06-05-2014 |
