IPC: A61B5/117
Filed: 1989-06-09
Abstract: A pattern image processing apparatus for collating image data of a finger read by a reader with previously registered feature data derived from the finger to verify the identity of a person, wherein light emitted from a light source (12) is radiated on a finger (10), and light reflected by the finger (10) is sensed by a camera (13). The finger image sensed by the camera (13) is converted to a digital signal and is sequentially added by an adder (15A) in a direction perpendicular to the longitudinal direction of the finger, thus generat­ing finger feature data P2(j). The generated feature data P2(j) is compared with the previously registered feature data P1(i) which was similarly generated and stored in a memory (18A). When a coincidence is found between these data, the person's identity is verified and a door (20) is opened. When a coincidence is not found, the person's identity is not verified, and the door (20) is not opened.

Abstract: A dynamic RAM for storing video frame comprises a first memory cell array (20 1 ) for storing an odd field of the video frame, a second memory cell array (20 2 ) for storing an even field of the video frame, a circuit (2, 4, 5, 22, 24 and 25) for receiving address signals and accessing a memory cell specified by the address signals in one of the first and second memory cell arrays, and a circuit (25, 23, and 23 2 ) for executing precharge of the other one of the first and second memory cell arrays which does not contain the memory cell specified by the adress signals. When a memory cell in one of the first and second memory cell arrays is being accessed, precharge is executed in the other array. Then when a subsequent memory cell is accessed, the access can be immediately executed because the precharge of the cell has already been finished.

Abstract: During an optimization of an organization of mutually-related elements, an element organization is gradually changed toward an objective specification by local changes of the element organization. A value of an objective function depends on a degree of a nearness of the element organization to the objective specification. A redundancy function of a number of elements in an improvement group is determined in consideration of a fluctuation in the value of the objective function, so that suitable changes of the improvement group are performed by use of the definite redundancy. An intermediate element organization is rejected and accepted in accordance with the redundancy function value, so that a final element organization can be obtained in consideration of a global aspect of the element organization.

Abstract: A magnetic thin film materials system (10, 10′) is provided, comprising a thin magnetic film (16) formed on a non-magnetic underlayer (14) formed on a substrate (12). In particular, the magnetic film comprises a composition consisting essentially of CoCrPt, with Cr ranging from about 10 to 20 at%, Pt ranging from about 1 to 20 at% and the balance Co. The underlayer consists essentially of chromium. The magnetic layer ranges in thickness from about 200 to 1,200 Å, while the non-magnetic underlayer ranges in thickness from about 500 to 5,000 Å. The plati­num controls film coercivity, while chromium provides corrosion resistance. In addition, chromium controls the recorded magnetic transition noise properties. An in­crease in Cr content in these alloys beyond about 10 at% increases the corrosion resistance and unexpectedly lowers the transition noise significantly. Coercivities of from about 500 to greater than 2,000 Oe and magnetization-­thickness products from 1 to 6 x 10⁻³ emu/cm² are attained by the magnetic recording system of the invention. A thin carbon wear layer (18) (about 200 to 800 Å) is provided over the magnetic layer, with an optional thin chromium adhesion layer (20) (0 to about 500 Å) interposed therebe­tween.

Abstract: An apparatus for nullifying the differential output offset voltage (ΔV OFFSET ) between the outputs (V+, V-) of a differential amplifier (200) and for setting the DC levels of the outputs to a known reference voltage (V REF ) includes a circuit (460, 462, 470, 472, 474, 476) which cross-couples the opposing AC output signals (V AC+ , V AC- ) to obtain only the DC components (V DC+ , V DC- ) of each signal. The apparatus further includes a first operational amplifier (440) to generate a compensation voltage (V OUT1 ) from the DC components of the outputs of the differential amplifier (200) proportional to the amount of offset between the DC components of the outputs of the differential amplifier (200). The compensation voltage (V OUT1 ) is fed back to the offset control inputs (382, 384) of the differential amplifier (200) to reduce the differential offset voltage (ΔV OFFSET ) to substantially zero volts. The apparatus further includes a dual voltage divider network (278, 280, 282, 284) having a second operational amplifier (450) that supplies a variable reference voltage (V CMR ) to one terminal of each leg of the voltage divider network (278, 280, 282, 284). The outputs of the differential amplifier (200) are each provided to a respective other terminal of the dual voltage divider network (278, 280, 282, 284). The second operational amplifier (450) has a reference voltage (V REF ) on one of its inputs (452). A signal responsive to the common mode output voltage from the differential amplifier is provided to the other input (454). The second operational amplifier (450) provides an output voltage (V CMR ) that is responsive to the common mode voltage output from the differential amplifier (200). The output voltage from the second operational amplifier (450) provided to the terminals of the dual voltage divider network (278, 280, 282, 284) varies such that the voltage outputs from the   voltage divider network (278, 280, 282, 284) have a common mode voltage substantially equal to the reference voltage (V REF ).

Abstract: An apparatus for controlling a power supply of an electric machine in a vehicle comprises primary (13) and secondary power supplies (16) for supplying an electric power to the electric machine. In non-driving state of an engine (11), the primary power (13) supply is selected as a power supply for the electric machine when an electric power consumption is over a predetermined value, and the secondary power supply (16) is selected when the consumption is below the predetermined value. Therefore, the absentee receiving of facsimile information, the absentee recording of telephone message, etc. are carried out, even in a state of turning-off of an ignition switch (14). The secondary power supply (16) is used mainly in the case that the electric machine is in waiting mode, so that the complete exhaustion of the secondary battery (16) can be prevented.

Abstract: A method for detecting the presence of a replacement disk in a fault tolerant, intelligent mass storage disk array subsystem having a microprocessor based controller in a personal computer system and rebuilding the replacement disk independent of the computer system processor. The method calls for the microprocessor controller to run a disk array check at system powerup or at specified intervals at which will detect the existence of a replacement drive. The microprocessor then builds a series of disk drive commands which attempt to read every sector on the replacement disk. The read commands will return a null data read, indicating that the sector must be restored. The microprocessor controller converts the replacement read commands for all sectors on the replacement disk to write-restore commands. The microprocessor executes the write commands and restores the data to the replacement drive.

Abstract: Since, in specific tape recorders which are provided for operation in motor vehicles, functions such as the lifting off of the rubber contact rollers from the tape are still to be controlled and monitored after the positive ignition voltage is switched off, it is necessary to connect the power supply which generates the voltage for a microprocessor to a continuous positive voltage. In order to avoid an unnecessary flow of current out of the car battery, measures are provided which cause the microprocessor to cut off its power supply from the continuous positive voltage after its activities are terminated. <IMAGE>
