Abstract: A light-emitting diode (LED) device (20) is disclosed which incorporates channels for distributing signals received from an external source directly into serially-connected LED array driver integrated circuits (ICs) of the LED device. Each LED array driver IC (21) comprises a plurality of input connection pads and output connection pads. Electrical power, drive data signals, clock signals, and control signals received via an input connector (25) and input board from the external source are supplied directly to the input pads of each LED array driver IC from the input board or an adjacent driver IC in the series without requiring a spreader board as found in prior art LED devices. Such arrangement permits smaller and faster LED devices than present LED devices. The drive data signals received at the predetermined input pads are converted to parallel signals by a serial-to-parallel shift register, and are then applied in parallel to the LED array, and serial data that passes through the shift register is outputted without modification to serial drive data output pad means.

Abstract: A semi-automatic pistol having a slide mounted to a frame is disclosed. The pistol has a hammer assembly (39) and a trigger bar assembly. A trigger bar (33) moves the sear (37) during firing, causing the sear to disengage the hammer (41). A safety is provided having a cam projection (55) which, upon movement of the safety, provides a caming action to urge the trigger bar downwardly, out of engagement with the sear. A second projection (57) moves to obstruct movement of the sear to prevent firing. Disengagement of the trigger bar from the sear in the safe position eliminates mechanical stress on a forward projecting arm of the sear.

Abstract: In the crystal structure of a polysilicon thin film (3) having a field effect mobility µ FE  of about 80 cm²/V·sec, the grain size is about 200 nm and the crystallite size on the (111) plane is about 180 nm. The crystallite size corresponds to the size of a completely monocrystallized portion of a grain. The condition of obtaining a field effect mobility µ FE  of about 80 cm²/V·sec is that the crystallite size on the (111) plane is at least 180 nm (measured value). By taking the crystal size into consideration, it becomes possible to achieve a high field effect mobility µ FE  which cannot be obtained merely by increasing the grain size.

Abstract: An electrically conductive polymer gel is composed a crosslinked polyacrylamide polymer including electrolytic salt, water and polyhydric alcohol uniformly dissolved therein, the water and the polyhydric alcohol being major components of said polymer gel. The polyacrylamide series polymer in the gel has properties of hydrophilic and nonelectrolyte. Therefore, a desirable connection between the gel and the electrode can be achieved with low impedance. Moreover, the polyhydric alcohol reduces the drying speed of the electrically conductive polymer gel, thereby preventing an increase in the impedance due to the dryout of the gel. Therefore, the electrically conductive polymer gel of the present invention permits an accurate measurement of an electrical phenomenon in the organism for long periods of time.

Abstract: In conventional LDMOS high voltage integrated circuits having floating wells, high voltage interconnects are necessary to connect the LDMOS transistors to circuit components within the floating wells. In such structures, high voltage cross-overs are used which create performance and fabrication problems. These problems are eliminated in a device according to the invention wherein the LDMOS transistors are provided with the floating well and spaced from the floating well circuit by a predetermined distance resulting in a predetermined parasitic resistance. This resistance may be used as a circuit element, e.g. for converting a signal current to a voltage signal. By providing the LDMOS transistors and the floating well circuit in one common floating well, the above mentioned high voltage cross-overs are avoided, together with the problems associated therewith.

Abstract: In order to be able to collect and convey mixtures of refuse bags, of which some (18) are bags for organic waste, these bags (17, 18) must later be able to be sorted in a quick and reliable manner, which can be effected by a method according to the invention which comprises conveyance on a system of conveyor belts on which the bags (17, 18) are aligned so that they stand in a line at a certain mutual distance, and are conducted to a sorting section (13) where they are visually scanned for the identification of the green bags (18) which are then sorted out. 
     The sorting is effected by means of a movable manoeuvring arm (28) having a lower end which describes an oval path of movement at a variable speed, and which is configured in such a manner that the movement in pushing the bag (18) is carried out quickly, while the slowing-down phase of the cycle takes place slowly. There is hereby achieved an expedient pattern of movement, so that the bags (18) can be sorted out, even though they are carried forward at a relatively high speed on the conveyor.

Abstract: A general method of accelerating the classification of an unclassified input symbol S into a library of pre-classified templates employs a comparison inequality function. The correlation calculation is initiated between the input symbol S and templates retrieved from the library of templates. Templates with a low degree of correlation are excluded prior to completion of the correlation calculation to accelerate the correlation. Sorting by template intensity permits the template foreground pixels to be correlated first, which also accelerates the correlation calculation. A second sort by discrimination power permits critical conflict pixels to be correlated first for further accelerating the correlation calculation.

Abstract: Techniques for multiple verification of credit cards incorporating digital image information and authorization data onto a credit card to assist in the card verification process. This technique requires the authorized card holder to have a picture identification accompany the application for the card. Picture information is converted to a digital image that is stored and used in one or a plurality of means for verifying that the presenter of the card, at the point of the transaction, is the authorized user. Such means include visual comparison of card presenter and extracted digital image information and verification that the data has not been altered. Encryption of the data, as it is read from the card, at the point of origin is used to formulate encoded authorization data that is then compared against like encoded authorized card holder data stored at a centrally located data base.
