The invention relates to a device and method for communicating with a thermal detector module and an appropriate thermal detector for a use with such a control device. The device for communicating with a thermal detector module comprises a means for providing a collimated beam of thermal infrared radiation and means for modulating the intensity of the collimated beam of thermal infrared radiation. The intensity modulated thermal infrared beam, when directed on to the thermal detector module from a position within the module's field of view, is suitable for triggering a response from the thermal detector module. The intensity modulated thermal infrared beam may also be encoded with a digital signal to control the function of the thermal detector.

Device and method for the calibration and control of thermal detectors

Apparatus for scanning a moving object includes a visible waveband sensororiented to collect a series of images of the object as it passes through a field of view. An image processoruses the series of images to form a composite image. The image processorstores image pixel data for a current image and a predecessor image in the series. It uses information in the current image and its predecessor to analyse images and derive likelihood measures indicating probabilities that current image pixels correspond to parts of the object. The image processorestimates motion between the current image and its predecessor from likelihood weighted pixels. It generates the composite image from frames positioned according to respective estimates of object image motion. Image motion may alternatively be detected by a speed sensor such as a Doppler radarsensing object motion directly and providing image timing signals.

Moving object scanning apparatus and method

A method of hermetically packaging an electronic device (), in an enclosure () comprising mutually inter-engageable first and second housing members (), comprising the steps of securing the electronic device () to the first housing member (), engaging the first () and second () housing members such that an hermetic seal is provided there between, wherein the engagement step is performed in a controlled atmosphere. The hermetic seal may be provided by an interference fit between the first () and second () housing members or via sealing means () interposed between the housing members (). The second housing member () may comprise an optical element (), for example a window or lens. The packaging method is particularly applicable to packaging thermal detectors, for example microbolometer arrays.

Hermetic packaging

An Array of detectors can be configured to be read as separate detectors, or to be connected into larger groups, e.g. groups of four (a 2&#xd7;2 array). This allows the formation of a relatively high definition image, and a much faster formation of a lower resolution image. This may be used with in an automobile to control deployment of safety airbags in accordance with a drivers position relative to the airbags. Preferably the array is a 64&#xd7;64 array of thermal detectors.

Reconfigurable detector array of resistance bolometers

A method of fabricating a micro-bridge device () onto a substrate (). The method includes the steps of: providing a sacrificial material () on a surface region of the substrate (); patternwise etching the sacrificial material (); providing a sensing material () on a surface region of the sacrificial material; providing a support material () on a surface region of the sensing material; and removing the sacrificial material () leaving support material () with the sensing material () on its lower surface, substantially free standing above the substrate ().
