Abstract: A keyless access control device and method for a vehicle having a door and a door handle includes transmitting a code from a transceiver while a cover covers the door handle to prevent a user from actuating the door handle. A transponder of the user transmits an answer to the transceiver upon receipt of the code. The answer is checked to conduct a preliminary verification of whether the user is authorized to access the vehicle. The cover uncovers the door handle if the preliminary verification indicates that the user is authorized to access the vehicle. A bidirectional question and answer dialog takes place between the transceiver and the transponder to conduct a final verification of whether the user is authorized to access the vehicle upon the user actuating the door handle. The door is unlocked if the final verification is indicative of the user having access to the vehicle.

Abstract: A wireless recording device can be interrogated to determine its identity and its state. The state indicates whether a particular physical or chemical event has taken place. In effect, the physical or chemical event is recorded by the device. The identity of the device allows it to be distinguished from a number of similar devices. Thus the sensor device may be used in an array of devices that can be probed by a wireless interrogation unit. The device tells the interrogator who it is and what state it is in. The interrogator can thus easily identify particular items in an array that have reached a particular condition.

Abstract: A transponder includes a data memory and a mechanism for contactless interaction with a base station. The transponder is brought (1) into an active field of the base station. Before the transponder is deactivated (7) by the base station by the transfer of a command signal (5), the authorization of the base station for deactivation (7) is checked (4). Before the transfer of the command signal (5) an admission signal which contains first admission information is transmitted (3) from the base station to the transponder. The first admission information with second admission information stored in the data memory is processed by the transponder into authorization information. Based on the authorization information it is decided (4) whether the command signal is accepted (7) or rejected (8). Thus the transponder while keeping secret the data present in the transponder may be reliably deactivated (7) or reactivated.

Abstract: A remote control signal from a remote controller (2) is received by one of remote control optical reception parts (4a to 4d), and the respective reception signals are decoded by decoders (11a to 11d). At this moment, the decoders (11a to 11d) extract an address code included in the reception signals received by the remote control optical reception parts (4a to 4d). Based on this address code, an effective-ineffective signal showing effectiveness or ineffectiveness of the decode signal is created. When the effective-ineffective signal shows effectiveness, a decoder selection part (12) adopts a decoder signal of the corresponding decoder.

Abstract: A keyless access control device and method for a motor vehicle includes a controller, transceiver, and a mobile transponder. The transceiver transmits a low frequency signal (LF) to the transponder and, in response, the transponder transmits a first high frequency (HF) signal to the transceiver. The controller moves a vehicle door handle into a position in which the door handle can be actuated by a user in response to receipt of the first HF signal by the transponder. The transceiver transmits a second HF signal to the transponder in response to actuation of the door handle by the user. The transponder transmits an encrypted HF signal to the transceiver based on the second HF signal. The transceiver processes the encrypted HF signal to determine whether the user is authorized to enter the vehicle. The controller unlocks the vehicle door in response to the transceiver indicating that the user is authorized.

Abstract: An electronic closure system has one or more lockable and unlockable closure units, each arranged on an opening element of an object to be secured, at least one authorizing authentication element and a closure control unit with at least one authentication element identification sensor. The at least one authentication element identification sensor has a predetermined detection area, which covers an external detection zone outside the object. The closure control unit produces different closure control commands, related to locking and/or unlocking, based on whether and in what external detection zone authorizing authentication element is detected.

Abstract: When a PIN need to use a protected device is manually entered for the time, it is encoded by means of unique identity number and stored in a PIN memory, the number is also used for the array in which or in connection with the device operates. If the user later identifies himself with an identity number which authorizes a subsequent use of the array, the encoded PIN stored in the PIN memory is decoded by means of the identity number and is made available to the device. Special advantages result when the environment is a vehicle and the device is a mobile telephone, since the network log-in takes place at the same time the vehicle is started with an authorized key.

The security system includes a security barrier, a locking mechanism for securing the barrier to a window frame, a radiant energy receiver operably connected to the locking mechanism, and a radiant energy remote control transmitter for signaling the receiver to release the locking mechanism so that the barrier may be removed.

Abstract: Transponders present in an interrogation zone can be identified by an interrogator by it sending an RF interrogation signal into the interrogation zone, the RF interrogation signal containing a code string prompting the transponders to generate partial addresses. As soon as one transponder “sees” that the generated partial address agrees with part of its own address, it responds by sending its full address which can then be read by the interrogator. Immediately after having received a full address the interrogator sends a code string characterizing the address of the transponder having responded before so that this transponder is thereby addressable. The signal sent by the interrogator to the transponder with this code string also contains an instruction which prompts the transponder to assume the condition in which it no longer responds to receiving its address or partial address.

Abstract: A remote control system for opening and closing a barrier, such as a garage door, includes an RF receiver and a plurality of RF transmitters. The transmitters and receiver include circuitry programmed to provide transmission of encrypted code signals each time the transmitters are used and employing a code hopping method which prevents unauthorized signal interception or code “grabbing”. The system is operated in a code learning mode for the receiver by momentarily actuating a receiver learn mode button for receiving each transmitter identification code and a secret decryption key for that transmitter with the system automatically returning to the operate mode. Each transmitter identification and secret key code signal is automatically and randomly stored in an available and unused memory in the receiver circuitry.

Abstract: A system for providing protected two-way communication between a shared control database (“base station”) and at least one remotely located protector module/remote unit uses a two-way pager system in conjunction with a communications host and a security algorithm. The security algorithm has the capability of producing a time-varying password, say every sixty seconds, and can be made part of a microprocessor housed in the protector module. Each protector module has a unique inherently assigned identification number (ID) which is verified and authenticated by the control database each time a message is received from the remotely located associated protector module. In addition, the system makes sure that each communication between the control database and a remote unit has a component which matches a predetermined electronic identification number (EIN).

Abstract: A method of locating an article or person employs at least one transponding station (TS1) having its own radio identity carded by a person or article in the radio coverage area of a radio system. The system employs a plurality of clusters of spatially separate radio units (M1 to M7) having transceivers and received signal strength determining modules, each of the radio units having an individual identity. Each cluster is associated with a network interrogating station (NIU(1), NIU(2)) employing transceivers for communicating with at least the radio units in its cluster. A central station (10) has a transceiver for communicating with a plurality of the interrogating stations and storage for storing a database encompassing the locations of the radio units (M1 to M7).

Abstract: A directed inventory system uses individual wireless pick-to modules, or individual wireless pick-from modules, or both, to aid inventory management services such as order fulfillment. Modules wirelessly receive servicing information directly from a processing computer, and transmit servicing status information directly to the computer. Light indicators or display panels on the modules provide information corresponding to a service to be performed, such as a quantity of parts to be picked from a bin, a location of a parts bin to pick from, a designation of a container to pick into, or other servicing information.
