Abstract: - 26 -MODULAR ADJUNCT PROCESSOR Abstract A voice-mail system (10) is assembled from one (100) or more (100-102) programmable multi-function boards all of which are interchangeable and physically identical. The voice-mail system functionality is distributed, on a function-by-function basis, among the modules of the system, each one of which can perform any one or more, or all, of the requisite functions. One of the modules is designated a master module (100). Under program control, it specifies to all themodules which functions that module is to perform. Under program control, each of the modules responds to the specification by loading itself with requisite programs whose execution will result in the performance of the specified functions. No separate and distinct resource-management module is needed.

IPC: G01R31/28
Filed: 1994-10-14
Abstract: An electrical control apparatus for the air bag system capable of inhibiting the diagnosis of back-up capacitors when a diagnosing routine is initiated by an extraneous noise. In a main routine executed by a microcomputer provided in an electrical control apparatus for an air-bag system, data stored in a specific address of a volatile memory is read out, and it is determined whether or not its value is the same as a fixed value. If the result is affirmative, it is determined that the main routine is started by an extraneous noise, an ignition flag IG is reset, and the diagnosis of the back-up capacitors is inhibited. On the other hand, if the data does not have the same value as the fixed value, it is determined that the ignition switch is turned on again after it has been turned off, the IG is set, and the diagnosis for back-up capacitors is carried out.

Title: Digital image recording device
Inventor: COLLETTE MICHAEL L
IPC: G03B19/10
Filed: 1994-06-06
Abstract: The digital image recording device includes a tri-linear array of photosensing elements which include a plurality of photosensor pixels. The tri-linear array of photosensing elements is mounted upon a frame for linear movement within a universal housing. The housing is adapted for insertion into the cartridge film slot of a standard view camera. The movement of the array of photosensing elements across an image plane within the standard view camera sequentially senses an image to be recorded. Each row of the tri-linear array of photosensing elements includes a separate color filter stripe which enables the color recording of an image during one pass of the scanner across the image plane. The array of photosensing elements is connected to a storage and processing unit by an electrical cable which permits communication therebetween. The storage andprocessing unit performs mathematical calculations to the electrically generated signals received from the tri-linear array of photosensing elements or image data primarily to correct for non-uniformities among the photosensing elements or in general to realign received signal information. Image realignment is then performed by a host computer electrically coupled to the storage and processing unit during the retrieval of image data from the camera. The storage and processing unit may be connected to a host computer having a view screen. The view screen and host computer enable a photographer tovisualize and adjust an image to be recorded.

Title: Motion Compensation Apparatus and Method of Gyroscopic Instruments for Determining Heading of a Borehole
Inventor: HACHE JEAN-MICHEL D
IPC: E21B47/022
Filed: 1994-09-07
Abstract: A method and apparatus is disclosed for measuring motion signals of gyroscopes in downhole instruments used to determine the heading of a borehole. An illustrative embodiment of the invention includes a measuring-while-drilling system which may experience motion even while the drill string is suspended in rotary table slips when the heading of the drill string is being determined. Accelerometer and magnetometer data along three orthogonal axes of a measurement sub are used to obtain unit gravitational vectors ~ at a first time and at a second time and unit magnetic vectors ~ at the first time and the second time. The difference between the two unit gravitational vectors at the different times, .DELTA.~, and the difference between the two unit magnetic vectors at the different times, .DELTA.~, are used along with the unit vectors ~ and ~ and the difference in time .DELTA.t to determine the rotation vector of the probe ~ which has occurred during such time difference. The vector representing the rotation of the earth, ~ is then determined by subtracting ~ from the vector ~ from three gyroscope instruments placed along the axes of the measurement sub. The heading of the drill string is determined from the gravitational vector and the earth rotation vector.

Title: Method and device for detecting a characteristic data grouping periodically inserted into a flux
Inventor: PINIER FRANCOIS
IPC: H04J3/06
Filed: 1994-11-08
Abstract: Method and device for searching for a characteristic grouping of data which is periodically inserted into a flow of successively transmitted data. Memory-storage means (7) temporarily store the received data sequence corresponding to the minimum subset necessarily including the grouping sought. Comparator means (8) search for a reference element relating to the grouping sought in a preselected area consisting of one of the modules subdividing the stored subset. The search is carried on module by module, until a group of data identical to the reference element is identified. Means (11) store the position of any group which is identical to the reference element in the module where such a group has been identified. A confirmation search makes it possible to eliminate the positions of the groups which are not subsequently found again, only the position of the last group present remaining, which is considered as the reference sought. <IMAGE>
