Abstract: A component carrier for holding a component includes a carrier substrate and a pocket recessed in the substrate for holding the component in its interior. The pocket has a wall and a floor, and the wall includes a series of elongated arcuate channels. The channels are concave relative to the pocket interior and extend substantially perpendicular to the pocket floor. The wall is substantially flat between the channels. A substantially continuous pedestal projects from the pocket floor. The pedestal has (i) an upper surface for supporting the component, (ii) a pair of support walls extending from the pocket floor and terminating in the support surface, and (iii) a notched portion intermediate the pedestal and defined by a lateral support member extending between the support walls and spaced from the pocket floor, for absorbing lateral components of compressive forces applied to the pedestal.

Abstract: An improved school bus door operator for a school bus, or other public transportation vehicle or bus. The improved school bus door operator of this invention consists of a linear actuated school bus door operator with a handle for operation by the driver and the linkage tying the operator to the school bus door. The linear actuated school bus door operator allows the driver of the school bus to open and close the school bus door with a back and forth short-stroke linear movement of the handle. This should reduce repetitive stress injuries which school bus drivers have occasioned. The improved school bus door operator generally consists of a handle slide mechanism, a rotatable pivot arm, and a door linkage arm engaged to the school bus door. The handle slide mechanism further consists of a slide arm that may be moved linearly within the handle slide mechanism. The slide arm has a handle that juts out generally in a vertical direction at a rearward portion of the slide arm.

Abstract: A time-shared multitask execution circuit for sharing registered digital hardware among a plurality of users is provided to achieve zero overhead switching while processing as few as 1 sample (in one clock cycle) for each user. The circuit comprises a three register bank, two switches, and a dual port RAM. On any given cycle of the clock, one register is processing data of a current user, one register is writing processed data of a prior user to the RAM, and one register is reading data of a subsequent user for processing from RAM. In this manner, processing, reading and writing are decoupled and proceed in parallel.

Abstract: A component carrier, for holding for purposes of automated visual inspection an electrical component having a lead with a free end, includes a carrier substrate and a pocket recessed in the substrate for holding the component in the interior of the pocket. The pocket includes a wall, depending from the carrier substrate and defining a lateral boundary of the pocket, and a bottom. There is a lead-tip horizontal plane and a lead-tip vertical plane when a correctly constructed component of the type the carrier is intended to hold is properly oriented in the pocket. The lead-tip vertical plane is perpendicular to a longitudinal axis of the pocket. The wall slopes down and inwardly at a first angle relative to the substrate through the lead-tip horizontal plane and at a second angle relative to the substrate through the lead-tip vertical plane. The first angle is greater than or equal to approximately 75.degree. and less than or equal to 90.degree., and the second angle is less than 90.degree.

Abstract: Apparatus adapted to hold a conventional hair dryer for the purpose of quickly drying a paint sample which includes a base member adapted to rest upon a horizontal surface, an upright support member extending from the base member, and a dryer retaining member having an aperture therethrough, disposed on the upright support member and spaced from the base member. The aperture is adapted to have a blower tube of a hair drier inserted downwardly therethrough, such that the body portion of the hair dryer will be retained against an upper surface of the dryer retaining member with the blower tube oriented generally downwardly through said aperture.

Abstract: The invention is a method of preventing active metal circuit corrosion on a semiconductor device. Non-corrosive multi-layers of metals are applied over the entire surface of a semiconductor, and then the multi-layers are etched to separate the portions on device contacts from the portions on the non-contact areas of the semiconductor device.

Abstract: Predetection noise bandwidth reduction is effected by a pre-averager capable of digitally averaging the samples of an input data signal over a single symbol, the averaging interval being defined by the input sampling rate divided by the output sampling rate. As the averaged sample is clocked to a suitable detector at a much slower rate than the input signal sampling rate the noise bandwidth at the input to the detector is reduced, the input to the detector having an improved signal to noise ratio as a result of the averaging process, and the rate at which such subsequent processing must operate is correspondingly reduced. The pre-averager may form a data filter when the output sampling rate is reduced to one sample per symbol of received data.

Abstract: A coherent phase and frequency recovery method capable of rapidly recovering the phase and frequency of bursts of received signals from plural sources. The received signal is applied to a first input of a mixer, the output of which is amplified and applied to two feedback paths, one for frequency and the other for phase. The frequency path contains a loop filter driving a voltage-controlled oscillator, and the phase path a loop filter and amplifier. Initial estimates of the phase and frequency of the present burst are derived and injected into the respective feedback paths. The output of the phase path is applied to correct the phase of the output of the frequency path, which is then applied to a second input of the mixer.

Abstract: The present invention provides a convertible top and support arrangement for the rear window. The present invention provides a convertible top with a top cover overlay type seal between the glass and cover. In the present invention's preferred embodiment, the window is cantileveredly supported at its rearward end. At its forward end the window is supported via a linkage with a cabled tension stabilizer. The arrangement provides increased stabilizing force with minimum tension in the cable or in the cantilevered support mechanism.

Abstract: Compressors are utilized in an apparatus for treating a product such as tobacco with a liquid cryogen, such as carbon dioxide for removing vapor from a processing chamber and recompressing the vapor to facilitate its return to the cryogen system. When the compressors do not receive a supply of cool vapor from the processing chamber, the compressor temperature rises and the pressure drops. When the pressure reaches a predetermined minimum setpoint, the compressors are interconnected by means of a remotely controlled valve to a vessel containing cryogen vapor at a pressure greater than the pressure at the compressors. A supply of cool cryogen vapor thus flows to the compressors to reduce the temperature, thereby allowing continuous operation of the compressors during periods in which cryogen vapor flow from the processing chamber is interrupted or delayed.
