Abstract: A miniature fan is mounted on a printed circuit board (PC board) and circulates air to help dissipate heat in enclosed electronic packages. The fan blades may rotate in a direction parallel or perpendicular to the plane of the PC board depending on available space. The method of mounting the miniature fan may be incorporated directly into the presently existing methods by which electrical components are mounted on a PC board, and which simplifies the mounting and manufacturing process such that mounting screws, lead wires, connectors, etc are eliminated, thus increasing efficiency and reducing cost.
Abstract: An overvoltage protection device having multiple shorting dots in the emitter region and multiple buried regions substantially aligned with these shorting dots. The placement, number, and area of these buried regions reduce and more accurately set the overshoot voltage value of the device while maintaining the high surge capacities of the device. Further, doping types and concentrations have been modified from that known in the prior art to reduce overshoot providing a more accurate and sensitive overvoltage protection device than that known previously in the prior art.
Abstract: According to the invention, a method and structure for flip chip interconnection of an integrated circuit chip to a substrate is provided. The method and structure of the invention overcome the problems associated with interconnecting the chip to the substrate by wirebonding and are less expensive than prior art flip chip interconnection methods and structures. Conventional integrated circuit chips that have been made using wafer fabrication processes for wirebonding chip-level interconnection are electrically connected to a substrate using a flip chip interconnection. Conventional wirebonding equipment can be used to bump chips for use in the invention.
Abstract: Disclosed is a device which provides a logic signal that indicates a true "on air" event during broadcast production. Each audio channel input from a microphone to a mixing console is coupled to a circuit arrangement which determines whether a mute switch is selected, a fader is set for full attenuation, or an input switch is deselected. If none of these events have occurred a signal is provided to an external display which is optically isolated from the mixing console. This signal controls a tally which indicates to a user that the corresponding input channel, for example, from a microphone is active.

Abstract: A planar fuse panel is presented. In accordance with the present invention, a section of conductive metal of the desired thickness, temper and shape is stamped out from a sheet of conductive metal. Simultaneously, a fuse holding spring mechanism or bent tabs, or blade terminals are formed in the same stamping operation for frictionally engaging fuses or other electrical connectors. The fuse panel includes a plurality of male blade connectors of a known configuration extending from the edges as well as other locations on the fuse panel to accept a variety of I/O configurations. A multiplicity of circuits may be included in the planar fuse panel (in a multilayer fashion) depending on the number of circuits desired. The circuits may have any suitable planar shape. Also described is a spring clip for use with the various fuseplanes.

Abstract: In accordance with the present invention, an apparatus for developing a latent image formed on a photoreceptor, which is deposited on an interior surface of an output window of a display device, is disclosed. The developing apparatus includes a developing chamber, having a support surface for supporting the output window, a screen structure material reservoir for storing, deagglomerating and feeding the screen structure material, and a triboelectric gun assembly communicating with the reservoir. The gun assembly triboelectric charges and imparts a desired charge polarity to the screen structure material. The gun assembly further includes at least one material dispersing nozzle spaced from the support surface for distributing the charged material for deposition onto the latent image.

Abstract: A signal acquisition method comprises the steps of recording ECG data signals on a tape in a first direction through a first high pass filter; and acquiring the data from the tape in an analyzer in a reverse direction through a second high pass filter having the same effective characteristics as the first filter.
Abstract: In an inverse transport processor of the type which directs video payloads of a packet signal to buffer memory space, apparatus is included for writing a media error codes at sequential first memory address locations in the memory ahead of each packet payload. Concurrently a processor examines the current packet to determine if it occurs in proper sequence. If a packet is lost, the payload is written to memory in subsequent sequential address locations. If there is no packet loss, the sequential first memory address locations are simply overwritten by the packet payload to excise the undesired media error code. Media error codes can thus be inserted in the packet payload stream without creating timing obstacles, for a system designer.

Abstract: A deflection apparatus comprises a deflection amplifier coupled to a deflection waveform modulation circuit such as a diode modulator. A source for generating a modulation signal. The modulation signal comprises a symmetrical periodic AC component having equal first and second portions of a trace period. A feedback amplifier alters the amplitude of a first portion of the trace period relative to a second portion of the trace period to render the AC component asymmetrical. The asymmetrical AC component is coupled to the deflection waveform modulation circuit for deflection waveform modulation.
Abstract: Film transport apparatus for a cine-video system in which video signals are produced from film that is driven between supply and take-up reels. The film, which may be wound in A or B configuration on each reel, is threaded automatically about a film drive mechanism which transports the film from the supply reel, through a film gate to the take-up reel. Tensioning apparatus imparts tension to the film at the entry and exit of the film gate which, during the threading operation, causes the respective reels to rotate before film actually is transported therebetween. The direction in which each reel rotates to unwind film therefrom when tension is imparted serves to identify whether the film is wound in A or B configuration. Advantageously, a programmable processor controls the film transport speed in response to a user-actuated knob; and this same processor serves to detect when the film approaches its end on the supply or take-up reel.

Abstract: In an inverse transport processor, program component packet payloads of respective program components are directed to select areas of random access memory (RAM) (18) in accordance with a plurality of start and end pointers which are stored in a first plurality (86, 89) of registers, one for each program component. Addresses are generated, in part, by a plurality of read pointer registers (82) multiplexed with an adder (80) to successively increment the pointers for respective program components. The start pointers are associated with read pointers to from memory addresses that scroll through designated memory blocks selectively assigned to respective program components. Memory access for read and write functions are arbitrated (98) so that no incoming program data can be lost, and all component processors are serviced.
Abstract: In an audio/video transmission system, a method of forming program guide information conducive to selective display at respective receivers includes arranging program guide information in different data blocks according to types of guide information. One such data block contains channel information (CSSM.sub.i) describing the respective channels. Respective CSSM.sub.i in this block include a channel information customer service system byte (CI.sub.-- CSS) which contains conditional access information related to a channel associated with a CSSM.sub.i. In a receiver embodiment, a subscriber specific byte (CA.sub.-- CSS) is stored and accessible to program guide processing apparatus. Prior to displaying received program guide information for a particular channel, the subscriber byte CA.sub.-- CSS is compared with the channel information byte CI.sub.-- CSS in the program guide.
