Patent EP-0468141-A3 (EP)
Title: Memory
IPC: G06F12/08
Filed: 1991-04-16
Abstract: Speeds up computer memory system operations by providing a memory fetch cycle that is shorter than the memory store cycle. To do this, the invention changes the timing of the recovery part of the fetch operation in the semiconductor memory chips of the memory. Each chip has at least one dynamic random access memory array (DRAM) and a small high speed cache memory (SRAM) on the chip. The system memory controller recognizes the fetch or store state of a memory request in generating a DRAM subrow-address timing signal (RAS) and a cache address timing signal (CAS) for enabling the accessing and addressing of bits in the SRAM and the recovery in the DRAM. The invention controls RAS to start DRAM recovery for a fetch cycle near the start of fetching of data from the SRAMs on the chips, but controls RAS to not start DRAM recovery for a store cycle until SRAM data storing is done. The clocks on the chips contain circuits that enable fetching of data from the SRAMs during DRAM recovery, but that prevent DRAM recovery from starting until data storing in the SRAMs is complete. <IMAGE>

Patent EP-0496986-A3 (EP)
Title: Packet data communication system
IPC: G06K7/00
Filed: 1991-12-11
Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. Direct sequence spread spectrum modulation is used for the RF link. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange.

Title: Forming board.
Inventor: DINGLER GERHARD
IPC: E04G9/05
Filed: 1993-12-08
Abstract: German Offenlegungsschrift 40 20 124 indicates that even forming boards made of plastic must have such a low coefficient of thermal conductivity that the setting concrete can cool down. If turning chips are used, these must be chemically cleaned since they have come into contact with lubricating drilling fluid. In addition, chips require an adhesive bridge to the plastic. The invention would like to avoid this type of pretreatment of the metal bodies. To do this, the invention uses ground foil shreds, where "ground" has a meaning in the sense of the technique of "cutting mills" or "cutting granulators". <IMAGE>

Title: Interface circuits for linear variable differential transformers
Inventor: DEVITO LAWRENCE M
IPC: G06G7/161
Filed: 1988-10-19
Abstract: A monolithic interface circuit for use with a linear variable differential transformer (LVDT) position transducer includes a drive circuit for providing an excitation signal of selectable frequency and amplitude to the LVDT primary winding. The interface circuit further includes a decoder responsive to signals induced in the LVDT secondary windings for computing the position p of the LVDT core as a solution to the equation p = K(A-B)/(A+B), where A and B represent the signals induced in the primary winding, and K is a constant scale factor. The decoder includes circuitry for rectifying (54,64) and filtering (56,66) the secondary signals (A,B), a charge balance loop (58,68,70,72,74) responsive to the detected signals for providing a binary signal having a duty cycle representative of B/(A+B), and an output circuit (80,82,86,88,90,92,94) responsive to the binary signal for providing the position output. The decoder provides excellent scale factor stability and linearity and is relatively insensitive to variations in primary drive amplitude. <IMAGE>

Title: Solid state peripheral storage device.
Inventor: HSU JUEI-CHI
IPC: G06F12/00
Filed: 1993-11-11
Abstract: A solid state peripheral storage device (10) receives an LSN (logical sector number) address from a computer system (12) and provides a mapping (74) to PSN (physical sector number) data. The PSN data is used to address memory units (80) made out of solid state floating gate storage cells. A microsequencer (50) controls the operation of the translation of the mapping (74) of the LSN to PSN and the accessing of the memory units (80). Through the use of the mapping of LSN to PSN, defective sectors in the memory units (80) can be mapped out and fresh, unused, defect-free sectors can then be replaced, all automatically, without user intervention. The microsequencer (50) has error recovery routines to further enhance the reliability of the peripheral device (10). Data to be written into the memory units (80) is initially transferred from the computer system (12) to a data register (35). The LSN address is stored in an LSN register (36). The data register (35) also serves as an output buffer store in a read operation. <IMAGE>
Patent EP-0619662-A3 (EP)
Title: Protocol for packet data communication system.
Inventor: TYMES LAROY
IPC: H04B1/713
Filed: 1994-03-30
Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer. Data packets are sent from the remote units by a spread spectrum RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. The remote hand-held units initiate an RF exchange to and from the base stations, receiving only during a time window following a transmission from the remote unit. The base stations cannot initiate an exchange with the remote units, but instead send data to the remote units only as part of the exchange. To alert a remote unit when a message is waiting at a base station to be sent to a particular unit, some of the acknowledge (base-to-remote) packets sent by the base station may contain an identification such as a list of all remote units (identified by ID number) which have messages waiting. Alternatively, a bit map can be used to identify these remotes. These base-to-remote packets with the identification of remotes with messages waiting are called "announcements." Each remote unit (if not engaged in regular exchanges for a time interval) periodically listens (activates its receiver) to receive an announcement packet containing such a list or bit map and decodes this announcement to see if it has a message waiting. If so, this remote unit then sends a transmit packet so the base can send the waiting message in an acknowledge packet.

Abstract: A power-generating voltage (Va-Vc) outputted from a
vehicle synchronous power generator (100) is adjusted to a first
voltage (Vref1) for charging a battery (9) under the control of
a field current. Further, a leading phase current (ix-iz) that
leads a phase voltage (Va-Vc) is supplied to each of multiple
armature windings (5a-5c) and the field current is supplied to
the field winding (4c), whereby the power-generating voltage (5a-5c)
can be adjusted to a second voltage (Vref2) higher than the
first power-generating voltage (Vref1). Owing to the above
construction, a voltage higher than the normal voltage can be
generated by supplying each leading phase current (ix-iz) from
the vehicle synchronous power generator (100); hence, power can
be supplied to a high-voltage load (10) based on the generated
high voltage.

Filed: 1996-07-11
Abstract: An image sensor assembly (10) is mounted in an optical system (60) having a plurality of
reference locators (66). The image sensor assembly includes an image sensing device (12)
having photolithographically generated elements, such as image sensing sites (24), and a carrier
package (14) for enclosing the image sensing device. The carrier package has externally
accessible reference features (32, 34, 36) that are optically aligned with respect to the
photolithographically generated elements on the image sensing device. Moreover, the
externally accessible reference features are used to exactly constrain the image sensor assembly
relative to the reference locators. Referencing the image sensing device to the same features
that are used for exact constraint removes the effect of material variations that may cause
dimensional changes and eliminates the need to activate the sensor for alignment of the sensor
assembly in the optical system.
