IPC: G01V1/36
Filed: 1990-09-25
Abstract: A method of seismic exploration uses recordings from both surface receivers and buried sensors to determine the full elastic effect of the near surface layer on an applied seismic wave. The surface receivers are arranged relative to the seismic source location so that rotational effects may be detect. Buried sensors are located so that vertical effects may be detected. This full elastic effect may be used in subsequent seismic data acquisition to reconcile the effect of the near surface so that the response of the underlying rock formations may be known.

Abstract: This invention relates generally to the static, random access, semiconductor memory arrays which incorporate split-emitter memory cells (2). The latter are accessed during a read cycle of a selected memory cell by precharging all the bit lines (B0, B1) of unselected memory cells associated with the word line (8) of the selected cell. This is accomplished by switchably connecting a voltage source (VREF2) to all the unselected bit lines which charges their bit line capacitances (CB0, CB1). Then, when read current sources (6) are switchably connected to both the selected and unselected memory cells (2) and the associated word line (8) is switched to a WORD SELECT source (VREF W), the read current (Io) associated with the unselected bit lines (2) flows via charging switches (S13) to the precharge voltage sources (VREF2) and the read current (Io) associated with the selected bit lines (B0, B1) along with dynamic current from uncharged selected bit line capacitances (CB0, CB1) flows into the selected cell (2). This approach prevents large, dynamic bit line currents from discharging the bit line capacitances of the unselected cells into those cells along with read currents.

Abstract: In an alarm system, the detectors of which contain, among other things, a microprocessor for exchanging data with a central station, relay-less detectors can be used with few exceptions if the following procedure is adopted for determining the configuration of the detectors:   - each detector is given a binary serial number by the manufacturer,   - in an initialisation mode, all serial numbers existing in the relevant system are determined, - in an individual addressing and response mode, an addressed detector responds with a current pulse, but stores the occurrence or lack of current pulses from other addressed detectors in the form of a binary pattern in the un-addressed state, - the central station interrogates the stored binary pattern from every detector and forms a first matrix from the pattern and the binary serial number of the relevant detector and a second matrix from the column sums and row sums of the first matrix, - the central station determines the system configuration by evaluating the first and the second matrix in accordance with a given algorithm.   <IMAGE>

Abstract: An improved method for manufacturing a laminate wherein the edges (12) of a deformable surface layer (14), such as cloth or carpet, are folded under and releasably secured to the undersurface (22) of the deformable surface layer. The deformable surface layer (14) is then placed into a mold unit (24,26) and the securement between the folded edge (12) and the undersurface (22) of the deformable surface layer is released either prior to or during the injection of a plastic material for forming a plastic support layer. The method produces a laminate comprising a deformable surface layer (14) having edges (12) which are folded under and totally bonded to the plastic support layer (18). The bonded edges improve the securement between the deformable surface layer (14) and the plastic support layer (18) and give the laminate a "finished" appearance without tacks or staples.

Abstract: A field configurable function element offers multi-function use of memory cells by organizing the cells in memory banks and by providing internal configurable interconnections of the memory banks. A versatile logic function configuration is obtained by storing the truth table of the desired logic functions in the memory cells. An arithmetic functions configuration is obtained by internally interconnecting the memory cells. A read/write memory function configuration is obtained by adding write address decoding, write enablement capability and input data leads. The configuration permits a parallel writing and reading of the memory cells, thereby effectuating a two- port memory operation. An added set of latches connected to the configurable function element and a configurable routing network connected to the inputs of the configurable function element, to the output of the configurable function element and to the output of the latches, form a powerful device that can be easily configured to any one of the three primary modes (logic, arithmetic and memory). A generalized routing fabric coupled to the routing network provides for configurable connections to other configurable function devices. To minimize the load that such a device may present to the routing fabric because of the various configurable interconnections that it can effect, the input leads from the routing fabric to the routing network in configurable function device are all multiplexed to one, or a few contact points, via an intermediate level of routing.

Abstract: Independent control of multiple samples which are in close proximity. All the samples in a sample container designed for rapid heat transfer and can be independently regulated to a set point using a temperature feedback control with the temperature monitored by a temperature sensitive element. This is implemented by heating each sample independently and at the same time a cooling means produces a substantial and continuous heat flow from the sample in order to permit an adequate rate of cooling when required. The rate of heat flow through the cooling means is partly determined by a thermal resistance which is including to control the pattern and maximum rate of heat flow to designed levels. By keeping the thermal mass of the temperature controlled components to a minimum it is also possible to change the temperature of the samples very rapidly.

Abstract: An energy function is defined as a linear sum of a discrepancy evaluation function and a dispersion evaluation function. Direction variables of all the subregions of a ridge direction pattern are variables of both evaluation functions. Direction variables are successively renovated along a line on which the energy function becomes minimum for a change of a concerned variable keeping all other variables unchanged. Reliabilities of initial directions in all the subregions are included as coefficients in the discrepancy evaluation function, and a higher reliability of an initial direction constrains the directional difference between the initial direction and the corresponding direction variable in a smaller amount. A set of variables which makes the energy function minimum is taken as a set of smoothed ridge direction pattern.
