摘要： A safety arrangement for use with a piece of equipment. The safety arrangement includes a signal generating unit for generating an optical signal, an elongate element, and a signal detecting unit. The elongate element is disposed along, about, around or through the piece of equipment and is capable of transmitting an optical signal. The signal detecting unit detects an optical signal. The signal generating unit is connected to the signal detecting unit by the elongate element such that the signal detecting unit is in optical communication with the signal detecting unit. The signal detecting unit is arranged to detect a change in the optical signal transmitted by the elongate element as a consequence of movement of the elongate element and, upon detection of the change in the signal, the detecting unit is configured to effect a change in the operation of the piece of equipment.

摘要： A feedback controlled laser diode communication device is disclosed that, as is common, has a laser diode that is modulated in response to an input signal to generate an optical signal, encoding the input signal. Spatially variable passband filter material, however, is arranged to receive at least a portion of the optical signal generated by the laser diode, preferably from the rear facet, and at least one detector is used to detect the thus filtered optical signal. Control circuitry then controls a wavelength of the laser diode based upon the response of the detector(s) to thus provide feedback control. As such, the device is particularly applicable to maintaining the tight channel spacings found in wavelength division multiplexed systems.

摘要： A fluorescent light source for backlighting a liquid crystal panel display consists of one or more u-shaped fluorescent elements in which the portion of the lamp segments containing the electrodes are bent at right angles to the principal light emitting portion. The low light emitting area in the vicinity of the electrodes is thus moved out of the light emitting area resulting in uniform light emission over the entire active area of the light source.The instant invention relates to a light source for a liquid crystal display and, more particularly, a light source utilizing fluorescent elements in which the low level emissions in the vicinity of the electrode portions of the lamp are kept out of the light emitting plane.
