A backlight for a display device, such as a liquid crystal display device, includes a light guiding plate having a front and a rear surface. The front and rear surfaces may be parallel to one another, or may instead be non-parallel. To the extent that such surfaces are non-parallel, one surface may be included at a single, or multiple angles with respect to the other surface. The backlight further includes a light source that is coupled to an edge of the light guiding plate by means of an energy...

A spread illuminating apparatus including a housing frame, the housing frame including respective positioning means for a light conductive bar, and a light conductive plate, and a recess for positioning a spot-like light source. The spot-like light source is mounted on a flexible printed circuit (FPC) that extends from a bottom surface of the housing frame through side and top surfaces thereof, and reaches the recess, in which the spot-like light source is housed. A cut-out for accommodating the...

A pulse modulator comprises a delay arrangement for receiving a first sequence of pulses and for delaying each received pulse several times to obtain a plurality of sequences of pulses having different phases. The pulse modulator further comprises a selection component for receiving from the delay arrangement a plurality of sequences of pulses having different phases, for receiving a modulating signal, wherein each possible value of the modulating signal is associated to one of the different pha...

Keyless entry includes a plurality of mobile devices each capable of fitting thereto a transponder for immobilizer authentication and a car-mounted device having a mobile device communication portion for communicating with the mobile devices and an immobilizer authentication portion for executing immobilizer authentication by making communication with the transponders. The immobilizer authentication portion includes a transmission/reception portion for communicating with the transponders, an ID ...

The present invention discloses a method and system for synchronizing processing modules. More specifically the present invention utilizes a master clock signal and associated synchronization information to coordinate the function dictated by packets within a synchronization stream. The master clock has multiple sources. Each module in the system is connected to each clock source to ensure that if one source fails, the module will not fail. The clock signal to each module is further passed throu...

Fast detection of a selected portion of a data packet (e.g. the preamble of a Bluetooth data packet) is accomplished by defining a reference signal waveform conforming to an expected waveform representing a signal modulated in accordance with the selected portion of a data packet. A waveform representing a received data signal containing a data packet with the selected portion is derived, and the reference signal waveform is correlated with this derived waveform to produce a correlation result. ...

A method of processing a signal representing an input sound signal is disclosed. The signal is divided in time into a plurality of signal segments, each having an individual duration of time. The signal segments are processed into an output signal of successive signal segments in such a way that at least one, preferably all, of the signal segments are repeated immediately and successively at least once in the output signal. Each signal segment is established in such a way that the duration of ti...

A web site contains a process which allows visitors to the site to view sensitive information contained in cryptograms in the site pages. During the site visit, controlling and key handling functions within the process automatically give the visitor an opportunity to enter keys to identify certain cryptograms in the site pages that the visitor is authorized to display. When pages containing the identified cryptograms are downloaded during the site visit, a decryption function within the process ...

A cork extractor includes a body having a pair of opposed side walls defining a gap therebetween and having a dimension that radially increases from a first end to a second end of the body. A hinge member is rotatably fixed at the first body end for turning about an axis, and a corkscrew is connected to the hinge member. The corkscrew is pivotable about the axis between a retracted position lying in the gap and an extended position for pulling a cork out from a bottle mouth upon the body being t...

A directional casing drilling system including a casing string for rotation of a drill bit, a shaft coupled to the casing string, and a sleeve having pads that are hydraulically extensible. The sleeve may be positioned about a portion of the shaft. The invention may also include a tube connecting the sleeve to the drill collar, the tube adapted to conduct drilling fluid, and a valve system adapted to operatively conduct at least a portion of the drilling fluid to the pads whereby the pads move b...
