Abstract: An edge illuminated optical detector array includes a series of two or more detectors which operate under an applied electric field. Each detector includes an extrinsic semiconducting active layer with a first conductivity type impurity concentration high enough to create an impurity energy band, and an intrinsic semiconducting blocking layer in which substantially no charge transport occurs by an impurity conduction mechanism. The detectors are positioned relative to one another such that optical energy incident on the array and directed substantially orthogonal to the applied electric field impinges on the first detector in the series and the portion of the optical energy which is transmitted by each detector is directed to the succeeding detector in the series. In this manner, the spectral content of the optical energy impinging on each detector is modified by the spectral transmission characteristics of the preceding detectors. 
     In a solid state photomultiplier detector embodiment, each detector also includes an extrinsic semiconducting buffered layer having a first conductivity type impurity concentration which is high enough to create an impurity energy band and a second conductivity type impurity concentration which is high enough that first conductivity type carriers injected into the buffered layer recombine with ionized first conductivity type impurities. Each active layer also includes a second conductivity type impurity concentration which is low enough that first conductivity type carriers photogenerated in the active layer can drift through the active layer without recombining with ionized first conductivity type impurities.

Abstract: Techniques are disclosed for determining orbital data of space borne vehicles including earth satellites such as those of the NAVSTAR Global Positioning System. Each of a set of such satellites (GPS-12-18) transmits signals which include carrier waves which may be suppressed or only implicitly present. The signals are received from the observable satellites concurrently by means of an antenna at each of at least three ground stations (STN 30-54) forming a network of baselines. The stations are arrayed such that the ratio of the length of the maximum to the minimum baseline length is much greater than one. From the signals received at a station pair, forming each baseline, a time series of doubly-differenced phase measurement data is formed which is biased by an integral number of cycles of phase. The data series for different satellite and station pairs are processed together to determine the orbits of the satellites and the doubly-differenced phase biases. Unique determination of the integer values of at least some of the biases is facilitated by the above noted spatial arrangement of the stations such that the ratio of the maximum to the minimum baseline length is much greater than one. This integer bias determination enhances the accuracy of the related orbit determination. 
     Unique determination of the integer values of at least some of the doubly-differenced carrier biases may also be facilitated by the use of carrier frequencies with the ratio of the maximum to the minimum frequency being much greater than one.

Abstract: A method for fabricating an integrated circuit having a buried doped region is disclosed. A thermal oxide layer (26) is formed over a portion of a p-type substrate (20) at which an n+ buried doped region (30) is not to be formed, masking the implant for the buried doped region (30). Anneal of the implant is performed in an oxidizing atmosphere, growing further oxide (28) over the surface. The oxide layers (26, 28) are removed, and a p-type blanket implant is performed for isolation purposes and, if desired, to form a p-type buried doped region (31); the doping concentration of the n+ buried doped region (30) retards diffusion of the boron to the surface thereover. Alternately, a higher, than normal doping level in the substrate can provide sufficient boron for isolation. An epitaxial layer (32) is then grown over the surface, and the n-well (40) is formed by implanting n-type dopant, with the p-well regions masked by a nitride mask; anneal of the n-well is also done in an oxidizing environment, so that consumption of a portion of the n-well (40) by the oxide (42) further planarizes the topography of the device.

Abstract: In hermetically sealing a base structure (10) of a ceramic package for a semiconductor device to a cap structure (12) of the device, one or more venting slots (36) are initially, according to the invention, provided in the base sealing layer (16) or in the cap sealing layer (26). The base and cap structures are then fused together along the two sealing layers and electrical leads (20) by bringing the structures into contact and heating them to a temperature high enough to cause the sealing material to flow readily. The venting slots allow air to escape during the fusing step. this inhibits the formation of air bubbles along the sealing interface and thereby improves the hermeticity of the seal. The structures are subsequently cooled to harden the sealing layers into a unitary layer (28).

Abstract: The apparatus randomly inserts crimped wire lead (22) (Fig. 1) one at a time into a multicircuit connector (12). The apparatus includes a pair of elongate insertion jaws (350, 352) (Figs. 21 through 25) for longitudinally surrounding and gripping a crimp terminated wire lead (22). The insertion jaws are actuable by a gripper control (128) between a first open position (Fig. 26) a second intermediate gripping position (Fig. 27) wherein the jaws are axially slidable along the gripped wire lead and a third closed position wherein the jaws firmly grip the lead in a non-slidable manner. The jaws (350, 352) and their gripper control (128) are mounted for axial movement along the wire lead into the insertion station (42). A drive (130, 132) for the jaws moves the jaws in their intermediate wire gripping position along the wire segment until a proximity sensor (58) (Fig. 3) senses the tips of the jaws abutting the rear end of the crimp terminal (26). In response to the sensor (58) the gripper control (128) changes the jaws to their closed position on the wire prior to insertion. The insertion jaws (350, 352) push on the rear end of the terminal (26) and do not rely   on the column strength of the wire during insertion of the lead (22) into the connector housing cavity (20). A programmable housing index module (68) is movable along X, Y and Z axes and a terminal guide jaw assembly (56) are provided for use with the insertion jaws to provide an apparatus capable of randomly inserting the leads (22) into the housing cavities (20) in any order.

Abstract: A voice language translator, suitable for implementation in hand-held size. The translator includes: a key pad (20); a display system (17); a language cartridge(s); a voice recognition module; a voice synthesizer; a speaker; a microphone; and a programmed CPU. Prior to use as a translator, the voice language translator is trained to the voice of a user. As the user speaks the words and phrases, the voice recognition circuit produces a digitally coded voice pattern that uniquely identifies the user. The voice patterns are analyzed and stored. Thereafter, during translation, when the user speaks a sentence, the voice pattern produced by the voice recognition circuit is compared with the stored voice patterns to determine the nature of the spoken sentence. The result of the comparison is used to locate equivalent translations stored in the cartridge. Strings of words and phrases that make up sentences are combinable only in a logical manner. Illogical combinations of words and phrases are ignored. If the translator does not understand a spoken word or phrase, a list of acceptable words and phrases is displayed. With a cursor a desired word or phrase can be selected. The logical string combinations of equivalent translations are converted to audible sounds. If desired, a visual display, or an audible emission, in the language of the user can be made to occur before the translated emission takes place.
