Abstract: A remote controller, a remote controlled electronic device, a remote control system for an electronic device and a remote control method for an electronic device are provided. The remote controller outputs a control code corresponding to a device ID, a device ID setting/change command and an operation command with respect to one or more electronic devices input from a user. The electronic device receives the device ID and/or control code from the remote controller and stores the received device ID. A control unit of the electronic device determines whether to operate in response to a control code received from the remote controller by checking whether the received device ID matches with the stored device ID. An output unit of the electronic device displays the device ID and/or a function in operation.

Abstract: The disclosed embodiments of the present invention are used to permanently disable or destruct an RFID so that it is no longer possible to read some or all of the data encoded on the RFID tag. In one method for disabling data on a radio frequency identification (RFID) tag, an RFID tag is identified and its identity is confirmed. Verification that a prerequisite event has occurred is obtained, occurrence of which is required prior to disablement of the data. A destruct instruction is transmitted to the RFID tag. The RFID tag verifies that the destruct instruction is valid and disables the data upon verifying validity of the destruct instruction. The tag may disable the data by erasing the data, disabling the data, auto-destructing, or performing any operation that makes the data unreadable.

Abstract: An electronic meter that is capable of handling an analog cellular phone or radio modem under the meter cover provides significant improvements in the thermal management and power handling that is associated with a circuit switched wireless device. The electronic meter comprises a power supply capable of delivering the transmitter power plus the associated losses due to transmitter efficiency. It is desirable to deliver the high power over a wide range of AC input voltages (typically from about 90 to 530 VAC). The meter packaging allows the power supply and the analog cellular modem to operate in an enclosed metering package without exceeding the operating temperatures of the electronic components. The packaging adapts to increased steady state (idle) conditions as well as increased transmit conditions.

Abstract: A downhole telemetry system having a surface transceiver, a cable, and a downhole transceiver coupled to the surface transceiver via the cable. The surface transceiver isolates an uplink signal from a combined uplink/downlink signal on the cable using time-domain signal cancellation. The downhole transceiver isolates a downlink signal from the combined uplink/downlink signal using time-domain signal cancellation. In the surface transceiver, the time-domain signal cancellation may be performed by running the combined uplink/downlink signal through a coil of a transformer while running a copy of the downlink signal through an opposite coil of the transformer. Likewise, in the downhole transceiver, the time-domain signal cancellation may be performed by running the combined uplink/signal through a coil of a transformer while running a copy of the uplink signal through an opposite coil of the transformer.

Abstract: A mud pulser controlled by a field applied to an electroactive fluid. The electroactive fluid is employed to act as a rapid-response brake to slow or interrupt the rotation of a mud motor or mud siren, thus creating pressure pulses in a circulating fluid. In certain embodiments, the electroactive fluid is used as a direct brake acting on a shaft rotating in a volume of electroactive fluid where the shaft is coupled to the mud motor or siren. The application of a field to the electroactive fluid impedes the rotation of the shaft, thus slowing the mud motor and creating a pressure pulse in the circulating fluid. In another embodiment, a Moineau pump circulating an electroactive fluid is coupled to the mud motor. The application of a field to the electroactive fluid slows the rotation of the pump, thus slowing the mud motor and creating a pressure pulse in the circulating fluid.

Abstract: A drill pipe forms an acoustic transmission channel for data to be transmitted from a downhole transceiver to a surface transceiver. By positioning a first low frequency acoustic attenuator between a drill bit and the downhole transceiver, acoustic noise generated by the drill bit is attenuated. Similarly, by positioning the surface transceiver between the top of the drill pipe and a second low frequency acoustic attenuator, acoustic noise generated by surface equipment is attenuated. In this manner, the first and second low frequency acoustic attenuators serve as terminators for the acoustic transmission channel.

Abstract: This invention is a photosite which allows access from a cell phone to provide user-friendlier services. The photosite creates an ID (S6501) and creates a character string Str from the ID by combining numerals and alphabetical characters by using a storage unit which stores buttons 0 to 9 of the cell phone and the number of alphabetical characters assigned to the respective buttons in correspondence with each other (S6502–S6507). In this case, a character string is created such that any two consecutive characters are assigned to different keys.

The keyboard has keys movably connected to the foundation sheet through scissors-type linking mechanisms. A plurality of guiding sheets is movably disposed on a foundation sheet and has hooks and tracks. Each of the tracks is parallel to a first direction. A sliding member is movably disposed on the foundation sheet and has protrusions extending into each of the tracks. When the sliding member moves in the first direction, the protrusions move the guiding sheets from a first position to a second position. The hooks of the guiding sheets sequentially press the scissors-type linking mechanism of each key to depress the keys of the keyboard from elevated position to depressed position.

Abstract: A method for transmitting and receiving messages in a home appliance networking system, wherein a first home appliance connected to a network appends a unique message identification number to a header of a message and transmits the resulting message to a second home appliance connected to the network.
