Title: Radar speedometer
Inventor: FRITZLEN J
IPC: G01S13/60
Filed: 1979-12-26
Abstract: Method and apparatus for measuring the speed of a land vehicle over a surface. A narrow beam (16) of RF energy is directed toward the surface (18) at a substantial angle. Reflected RF energy is mixed with that transmitted to produce Doppler signals having a spectrum. The spectra of the Doppler signals are normalized by the Doppler signals being applied to an AGC circuit (26) so that the maximum amplitudes of the spectra are substantially constant and being applied to one or more tracking band pass filters (30, 32, 34) which eliminate unwanted frequency components in the spectra. From the normalized spectra, output signals are produced from which can be determined the speed of the vehicle relative to the surface.

Title: Organization for dynamic random access memory
Inventor: CENKER R
IPC: G11C11/408
Filed: 1980-01-28
Abstract: An MOS dynamic random access memory (RAM) includes an array of memory cells arranged in rows and columns. The array is divided into two or more sub-arrays (1001, 1002). In an operating cycle where a cell is being accessed for reading and/or writing, only the sub-array containing the accessed cell is fully selected while the other sub-arrays are partially selected. A fully selected sub-array is one in which both a row and a column are selected, whereas in a partially selected sub-array, only a row is selected. In the partially selected sub-array where only refreshing of the cells in the selected row takes place, the column (1003, 1004) decoders and drivers remain inactive throughout the memory cycle.

Title: Non-pressurized dispensing system and composition
Inventor: HINTZ W
IPC: B01F23/00
Filed: 1980-04-08
Abstract: A water-in-air emulsion or suspension containing a dispensible material is formed by stabilization of small droplets (48) of aqueous liquid with an interfacial barrier of very fine, hydrophobic metal oxide particles (42) such as silane modified silica. As the droplets (48) are subjected to shear such as during passage through an orifice (28), and/or on the surface of the target, the shear forces experienced at least partially destabilize the barrier allowing the droplets to coalesce to form particles of controlled density and increased size and eventually can be totally destabilized into an elegant cream or lotion. At least 10% of the droplets may coalesce into particles after leaving the orifice. Active ingredients such as antiperspirants may be added to either the aqueous liquid phase or to the powder phase as long as they do not destabilize the suspension. A non-pressurized system comprises a container (10) suitable for dispensing the suspension having a compartment (14) receiving the suspension, a valve means (18) having an outlet orifice (28) of a dimension adapted to impart a preselected shear and destabilization to the suspension and the container being adapted to enable the suspension to be propelled through the outlet orifice. Other dispensing systems include shaker-top containers and roll-on applicators.

Title: Double exposure interferometric analysis of structures and emplo ying ambient pressure stressing
Inventor: GRANT RALPH M
IPC: G01M17/02
Filed: 1983-07-21
Abstract: In order to detect subsurface defects in a vehicle tire, the tire (24) is placed in a sealed pressure chamber (12 and 14) and the pressure is rapidly reduced to a very low level, and maintained at that level for a period of time. The body of the tire (24) creeps for a period of time following the pressure change as a result of the stresses imposed by the pressure change. During this creep period a section on the surface of the tire is illuminated with coherent light and two separate exposures of interferograms are made using the reflected light and recorded on either a photographic media or the cathode of a television image tube. The exposure may either be holographic, in which case the interferogram is produced by using a reference beam of light derived from the same source that illuminates the object surface, or shearography, in which case two focused images of the tire surface section are formed on the photosensitive media, displaced with respect to one another and overlapping one another. The resultant hologram or shearogram is processed in the normal manner to derive an image of the object surface containing fringes arrayed as a function of the deformation of the surface between the two exposures. These fringes are analyzed either by a computer or an operator, to detect anomalous fringe families related to subsurface defects in the tire section.

Title: Technique for the transmission of video and audio signals over a digital transmission system
Inventor: TU PETER JING
IPC: H04N7/04
Filed: 1984-12-06
Abstract: A technique for transmitting both a video signal and a plurality of audio signals within a predetermined signal format not normally used for television transmission. The video signal is sampled and digitized (11) at a first multiple of the video subcarrier frequency. The digitized video signal is then multiplexed (41) with a plurality of audio signal bits into a N-bit frame format using a second multiple of the video subcarrier frequency which is less than the line frequency of the known signal format. The N-bit frame format is than sectioned into Y-bit subframes and multiplexed (42) with auxiliary and monitoring bit information (18), e.g. framing bits, using a third multiple of the video subcarrier frequency to generate a system signal format which is compatible with the known signal format. At a receiving end the system signal format is demultiplexed in a complimentary manner to the multiplexing sequence of the transmitter.

Title: Precision control frequency synthesizer having an unstable, variable frequency input signal
Inventor: GRIMES GARY JOE
IPC: H03L7/14
Filed: 1985-01-29
Abstract: A precision controlled frequency synthesizer which is capable of precisely adjusting the frequency of an output signal to maintain a desired frequency difference between an input and output signal regardless of the stability of the frequency of an input signal. The synthesizer comprises the basic elements of a phase locked loop (PLL) type circuit. The PLL circuit portion detects the actual frequency difference, a value A, between the input and output signals. One reference source provides a desired frequency difference, a value D, which represents the frequency difference between a stable input frequency and a desired output frequency. The difference between the frequency difference values A and D serves as the amount of adjustment to the frequency of the output signal. This adjustment represents the amount of compensation necessary to maintain a specified frequency relationship between the input and output signals.
