Abstract: Systems and methods for remote control of a wireless communication device are provided. Remote access to a wireless communication device is obtained through a packet switched mobile terminated data call. The data call can also be originated from the wireless communication device. Authentication and validation procedures facilitate secure remote control access to the wireless communication device by one or more remote control access points. Once a remote control access session has been established, the remote control access point can execute commands on the wireless communication device, including initiating voice calls and scheduling future commands. Additionally, an audio-video teleconference can be initiated using streaming video and voice over IP.

Abstract: In this process for controlling at least two groups of antennas, a coded signal (26) is emitted by a first group of antennas, whilst the antennas of a second group emit a residual signal (28) similar to the coded signal but of lesser amplitude. The coding used in this case is such that the coded signal (26) has dead time. A parasitic signal (34) is sent to the second group of antennas (6) during dead time of the coded signal (26) sent to the first group of antennas.

Abstract: An identification system is disclosed in which an interrogation signal is emitted on the side of the object, the signal having a carrier frequency which is modified in sections. A mobile encoder (20) encodes the interrogation signal and produces a response signal which is sent back to the object (10). The response signal is mixed with the interrogation signal and decoded in an evaluation unit (14–16) on the side of the object. The distance (d) between the encoder (20) and the object (10) is then determined by means of Fourier transformation (16).

Abstract: An anti-theft system comprises a digital code in a key ring. The code is transmitted to a client box installed in a car. The box analyses the code and, in the case of theft, transmits a distress signal to a surveillance station. The surveillance station is equipped with a receiver and a display to display information concerning the stolen vehicle. A person at the surveillance station can stop the stolen vehicle or can use a switch on the surveillance station unit that sends a signal to a receiver in the client box and thus turns off the fuel pump of the car.

Abstract: A device for controlling a controlled device includes a remote control unit having a transmitter, a processor, a clock connected to the processor, and a control keypad. The remote control unit is removably engageable in a support, and when the remote control unit is in a first position relative to the support, manipulation of the keypad results in sending programming commands to the processor such that the processor can transmit control signals to the controlled device at user-defined times. On the other hand, when the remote control unit is not in the first position relative to the support, manipulation of the keypad causes the transmitter to send commands to the controlled device. Alternatively, when the remote control unit is in the first position relative to the support, the keypad is disabled, such that commands may be sent to the controlled device from the device only automatically at preprogrammed times.

The box is mounted movably in a support between a first position corresponding to the first operating mode and at least one second position corresponding to the second operating mode. Means are provided for detecting the position of the box with respect to the support and means are also provided for modifying the operating mode as a function of the detected position of the box.

Abstract: Remote control of an operating table which can be motor-adjusted by means of a drive device is provided for. Command signals for controlling the drive device are wirelessly transmitted to the operating table from an operator control unit. A unique association between the operator control unit and an operating table is ensured before command signals are sent by emitting an infrared control signal to the operating table by the operator control unit and then confirming the reception of the control signal from the operator control unit by radio signal from the operating table.

Abstract: A method of transmitting digital signals which are passed via a communication system by means of a retimer between an input and an output, whereby according to the invention the data packet applied to the input is scanned with respect to the individual bits and within the individual bits and preferably at the center and the scanned data level is transmitted immediately to the output.

Abstract: An anti-collision method to identify and select contactless electronic modules (MDL) by a terminal is provided. A module may generate a random identification number prior to a communication, and respond to a general or complementary identification request on a time slot that varies according to its identification number. A non-selected module may generate a new random identification number when it receives a complementary identification request. Thus, the time slot of a non-selected module provided in response to a complementary identification request is not statistically the same as its time slot in response to a previous identification request, and it varies according to its identification number (ID).

Abstract: When a door sensor is touched, a vehicle-mounted unit and a portable unit performs mutual communications for authentication, and the doors are unlocked. When the door sensor is touched without intending to unlock the doors, wasteful consumption of electric energy is avoided which would otherwise result from mutual communications for authentication triggered by a request signal. When the door sensor may possibly be operated not for the purpose of unlocking the doors, e.g., when a CPU detects the doors as being already unlocked from a signal outputted from a door lock knob switch, a request signal is inhibited from being transmitted from the vehicle-mounted unit to the portable unit.

The domestic hand held garage door opener transmitting unit transmits a second signal to actuate the door opening device to open or close the door.

Abstract: A method of reading a plurality of transponders 14.1 to 14.n forming part of an electronic radio frequency identification system 10 comprises the steps of prompting the transponders at 38 to transmit preambles 30 only of respective response digital sequences to a reader 12. The reader then locks onto the preamble 30 transmitted by one of the transponders and immediately causes a mute signal 38 to be broadcast to mute all of the transponders not yet transmitting. The reader then transmits during a first time window 42 a first command 40 to cause the one transponder to transmit a remainder of the sequence. Having received and read the remainder, the reader transmits a second command 44 during a second time window 46 to cause the one transponder to switch to a sleep mode wherein the one transponder no longer transmits any part of the sequence, and to unmute the muted transponders.

Abstract: A SAW RFID tag or sensor has an antenna for receiving and propagating an RF signal, an input/output IDT electrically connected to the antenna, and a dual track reflective IDT having a first track and a second track located adjacent and acoustically coupled to the input/output IDT. An RF signal received from the antenna by the input/output IDT is transformed by the input/output IDT into an acoustic way which is propagated to the dual track IDT. One track of the dual track IDT is in-phase with the phase reference of the input/output IDT and the other track is in quadrature phase with said phase reference. The input/output IDT receives two orthogonal complex modulated acoustic waves reflected from the first and second tracks and transforms them to a modulated orthogonal complex RF signal which is propagated from the antenna.
