Abstract: A code locking mechanism that transmits information between a key and a locking mechanism secured against interception misuse, but flexible with respect to original equipment, replacement parts, and emergency functions, is obtained if the key code is, in each case, cryptographically encoded through a hardware encoder. When the locking mechanism is first operated, a control element, inductively coupled to a locking mechanism read-write unit with a new key once and in a non-overwritable manner, transmits an indent number to the object memory. Object-specific identity data are also stored in the control element. With the latter, a key number from a key register of the control element is combined with the key code to read the latter together with a roll-in random code into the set of first still-neutral keys and into the object memory. Thus, a key is valid only if the object-specific identity data are taken into account in its key code.

Abstract: A system for remote information exchange between a portable object and a station and in which in order to minimize an undesirable profitless cluttering in the radio frequency environment of the system, the phase variation between the first and second alternating voltages (VEX and VEY), which is induced by the switchings of the electronic circuit of the portable object as a function of information to be transmitted to the station, enables the station-processing means (SPM) to deduce the information therefrom, and the elements of the electronic circuit and of the station are chosen and configured so that the phase variation induce by the inductive coupling is greater than a predetermined threshold.

Abstract: An identification device is provided which includes an inactive code carrier, such as a standing acoustic wave component, a frequency mixing section, and a double antenna input. Each of the antennas are tuned to a separate predetermined transmitted signal wherein the frequencies are different. The two separately received RF frequencies are mixed to produce an intermediate frequency having the sum or difference of the two received frequencies. The intermediate frequency is coupled to the standing acoustic wave device which applies a coded signal to the intermediate frequency. The intermediate frequency is then recombined with one of the original incoming RF frequencies to be retransmitted from the identification device. The mixer section can include a diode and a coil for matching the impedance of the incoming signal with the inactive code carrier.

Abstract: An access controller for a television, computer or display device includes a wireless transmitter and a receiving unit. The receiving unit has a tamper-proof housing that covers the device power line and protects receiving and switching circuitry. The receiving circuitry receives and demodulates a control signal sent by the transmitter, and drives the switching circuitry between ON and OFF states. In a preferred embodiment, the housing has opposed halves which close about the device plug. A pigtail line cord extends from the housing and provides power through the switch, to the device plug. The housing itself is featureless, and the transmitter is an inconspicuous, pocketable, push-button device, so the TV or other device may be controlled without physically approaching or otherwise revealing either the nature of the control mechanism or even that the operator is exercising control.

Abstract: A radio selective call receiver with display includes, a storage device for storing at least received messages, a display device for displaying the received messages, an adder for associating the retrieval attribute to the received messages, and a retrieving mechanism for retrieving the received messages on the basis of the retrieval attribute. The retrieval attribute can be selectively added at any time of reading out a received message or when displaying the message at a time of reception. Further, an added retrieval attribute can be selectively changeable or deletable any time after reception of the message, and a received message, not requiring retrieval, may have no retrieval attribute set, thereby to exclude the received message from retrieval messages.

Additionally, the device provides a plurality of data paths for allowing the MPU to read data from the store terminal, for storing and reading data from the store controller, and for transferring data between the MPU and the peripheral unit.

Abstract: A moving object identification system with a novel coding scheme achieves 75% transmission efficiency. With this system, a transmittable range is expanded. Logical value assignment for residual resonant oscillations in a residual resonant signal is performed by comparing a residual frequency with a threshold frequency. A wave energy reduction of an ASK modulated signal is used to decrease the energy of the signal in order to distinguish similar residual frequencies in the case of extremely close communication. Reliability of Write/Read instructions in this system is improved by employing a test writing before an actual writing and a voltage monitoring device.

Abstract: A vehicle operator identification verification system that correlates an operator identification code with certain vehicle conditions such as seat position and side mirror position. A personalization command system receives the operator identification code from a key fob transmitter, and correlates the identification code with stored identification codes. The command system will then initiate various adapting systems that correspond to the received identification code. Further, the command system will cause various personalization devices, such as seats and mirror positioning devices, to be actuated to a position corresponding to a stored position associated with the received operator identification code. If one or more of the various personalization devices are adjusted by the vehicle operator a certain percentage beyond the settings that correspond to the received operator identification code, system will prevent the adapting systems from adapting to the current vehicle operator.

Abstract: A fixed system receiver (107) operates in a synchronization mode which is one of a synchronous mode and an asynchronous mode. A system controller (102) transmits a response command which includes a preamble indicator corresponding to the synchronization mode of the fixed system receiver (107). A selective call radio (106) receives and decodes the preamble indicator and generates a response message data unit (312). The synchronous header data packet (660) is preceded by a synchronizing packet (650) when the preamble indicator indicates the asynchronous mode and is not preceded by the synchronizing packet (650) when the preamble indicator indicates the synchronous mode. The selective call radio (106) transmits the response message data unit (312). The fixed system receiver (107) acquires symbol recovery timing and synchronizes to data packet boundaries of the response message data unit (312), using the synchronizing packet (650) when included.

Abstract: A field programmable interconnect device (FPID) selectively routes signals between signal ports in response to commands from a host controller. Each command includes an address and data. The FPID includes an array of switch cells, each interconnecting a separate pair of the ports and each having first and second control signal inputs. When the first and second control signals are both asserted, the switch cell provides a signal path between the pair of the ports it interconnects. The FPID includes first and second sets of memory cells for storing data. Each first memory cell corresponds to a separate one of the switch cells and selectively asserts or deasserts the first control signal input to the corresponding switch cell according to its stored data. Each second memory cell corresponds to a separate group of switch cells and selectively asserts or deasserts the second control signal input to each switch cell of the corresponding group according to its stored data.

Abstract: Partitioned point-to-point communications networks and configured to include a plurality of overlapping network portions, from "fully connected" point-to-point communications networks that are being expanded (to include additional sites), reconfigured and/or which are being upgraded (or otherwise modified) to support new and possibly incompatible communications protocols. The partitioning facilitates adding sites to a fully connected network, particularly where a predetermined maximum network size is reached, without having to redesign the network. In addition, modifying communication protocols used in such a network (for example, when upgrading a portion of the network to support a new feature), without having to change protocols for all sites at once is facilitated.

Abstract: A paging receiver receives a message data including an overhead and a body data. The paging receiver has a first memory with multiple memory slots for holding the body data from multiple message data, and a second memory for holding information about the current storage methods for memory slots of the first memory. The overhead of the message data specifies a memory slot number for storing the body data, and also specifies a method of storing the body data, which may be storage by replacement of current contents, storage by combination with current contents, etc. A controller of the paging receiver selects the storage method from the second memory if the overhead does not specify the method of storing the body data, but uses the method specified in the overhead when present. The body data of the message data is placed in the specified slot of the first memory using the method selected by the controller.

Abstract: A communication transceiver (510) having a receiver (704), a controller (714) and a transmitter (710), is used for generating an unscheduled acknowledge back response. The receiver (704) receives an address and a color code identifying the cell transmitter (506) transmitting the address during a first scheduled time interval (212). The controller (714) selects, in accordance with the address received, a reserved response time slot from a predetermined number of reserved response time slots occurring during a second scheduled time interval. The transmitter (710) then transmits the unscheduled acknowledge back response during the reserved response time slot (224) selected.

Abstract: A method of controlling communication for a communication system for connecting a plurality of electronic apparatuses through a communication control bus and allowing data communication between those electronic apparatuses wherein each of the electronic apparatuses performs connection control through the execution of a connection control command carried out by writing connection control information in a predetermined storage memory of its own or another electronic apparatus. The electronic apparatuses which attempt to write the connection control information transmit the write instructions to a predetermined storage memory. The storage memory which has received the write instructions, in turn executes only the earliest write instruction received and then transmits responses indicating whether the execution of the respective write instructions was successful or not.
