In an organic memory which is included in a radio chip formed from a thin film, data are written to the organic memory by a signal inputted with a wired connection, and the data is read with a signal by radio transmission. A bit line and a word line which form the organic memory are each selected by a signal which specifies an address generated based on the signal inputted with a wired connection. A voltage is applied to a selected memory element. Thus writing is performed. Reading is performed by a clock signal or the like which are generated from a radio signal.

In a satellite receiving system, program channels are selected from one or more broadband signals and combined with other selected channels and transmitted from a first unit, for example an outdoor unit, to a second unit, for example a gateway, server, or set-top box, using a single cable. Channels can be selected by digitizing the broadband signal then digitally filtering to isolate the desired channels. The outputs of several LNBs can be selected and combined into one signal. Multiple set-top boxes can receive independent signals over a single cable from the outdoor unit.

A multimedia processing system includes a selector, an output playback apparatus, a controller, and an A/V signal detector. The selector has a plurality of input ports for receiving multimedia signals and for selecting and outputting one of the multimedia signals according to a selection control signal. The output playback apparatus is used for playing the multimedia signal outputted by the selector in the output playback apparatus. The controller is used for generating the corresponding selection control signals to the selector. The A/V signal detector is used for detecting whether the input ports of the selector have received a newly inputted multimedia signal. When a newly inputted multimedia signal is detected, the A/V signal detector outputs a specific selection signal to the controller, so the controller subsequently generates the corresponding selection control signal to the selector for selecting and outputting the newly inputted multimedia signal to the output playback apparatus.

In an adaptive modulation and coding method one or more adjustable values are created (S1), each corresponding to at least one of a plurality of available modulation and coding levels applicable to a signal transmitted from a transmitter to a receiver, and each representing a change to the level(s) to which it corresponds. One or more of said adjustable values is/are adjusted in dependence upon whether or not the signal is received successfully by the receiver (S2-S5). One of said available modulation and coding levels is selected (S6-S8) to apply to the signal based on such an adjustable value. Such a method can enable the appropriate modulation and coding level to be selected even when the path and channel conditions vary. The method is applicable to selecting modulation and coding levels in a high-speed downlink packet access system of a wireless communication network.

Apparatus and methods are described for selecting which of a plurality of simultaneously activated keys in a keyboard based on capacitive sensors is a key intended for selection by a user. In embodiments of the invention keys are preferentially selected as the user intended key based on their positions within the keyboard. Thus a key which is frequently wrongly activated when a user selects another key, e.g. because the key is adjacent the intended key and the user normally passes his finger over it while approaching the desired key, can be suppressed relative to the desired key based on their relative positions. For example, keys may be associated with predefined rankings according to their position within the keyboard and in use keys are preferentially select according to their rankings. Alternatively, signals from the keys may be scaled by weighting factors associated with their positions and a key selected according to the weighted signals.

Within one pixel element 200, two display circuits corresponding to the analog display mode and the digital display mode are disposed such that they are adjacent to each other. One of these two display circuits can be selected through the circuit selection circuits 40 or 43. Since the high voltage power line 150 of the retaining circuit 110, which is used under the digital display mode, also performs as the signal selection line 88, it is possible to have the high density integration of the pixel element 200. Also, the bias voltage Vsc supplied through the selection storage capacitor line 81 is same as the signal A. Therefore, the storage capacitor line 81 is connected to the drain of the TFT 122 of the signal selection circuit 120 so that the signal line 82 for supplying the signal A can be omitted. Thus, the high-density integration of the pixel element 200 can be achieved.

A bit synchronizer for a digital receiver system accounts for loss of bit synchronization due to transmission phenomena. The bit synchronizer includes a DC level estimator for converting a sampled digital signal having a bit rate and a sampling rate into a level-adjusted signal. A delay module generates a first timing signal, a second timing signal, and a third timing signal based on the level-adjusted signal. The timing signals correspond to early, on-time, and late sampling windows. The control module generates an output signal based on the timing signals such that the transmit and receive bit timing are synchronized. In one embodiment, the control module has an absolute value stage, an integration stage, and a signal selector. The signal selector is able to select between the timing signals, adjust the symbol rate to re-center the on-time gate, and memory swap to maintain correct averaging operations.

A method and apparatus are described for a User Equipment (UE) to transmit in a control channel ACKnowledgement signals associated with a Hybrid Automatic Repeat reQuest process (HARQ-ACK signals) in response to receiving Transport Blocks (TBs) transmitted from a base station. The UE conveys the HARQ-ACK information by selecting one resource from multiple resources in the control channel and by selecting a constellation point of the modulation scheme for the HARQ-ACK signal. Transmission diversity is supported using different control channel resources that are already available to the UE without configuring additional resources. Design principles are described to optimally map the HARQ-ACK information to control channel resources and modulation constellation points for a Time Division Duplex (TDD) system and for a Frequency Division Duplex (FDD) system.

A CMOS imager includes an array of active pixel sensors, wherein each pixel is associated with a respective column in the array. The imager also includes multiple circuits for reading out values of pixels from the active sensor array. Each readout circuit can be associated with a respective pair of columns in the array and can include first and second sample-and-hold circuits.

Each readout circuit also includes an operational amplifier-based charge sensing circuit that selectively provides an amplified differential output signal based on signals sampled either by the first sample-and-hold circuit or the second sample-and-hold circuit. The readout circuit also has an analog-to-digital converter for converting the differential output to a corresponding digital signal using a successive approximation technique. Use of the readout circuit can increase the parallel structure of the overall chip, thereby reducing the bandwidth which each readout circuit must be capable of handling.

At least two coils deliver at least two time-varying magnetic fields to a target region within a body. The coils are oriented such that the magnetic fields create intersecting electric fields in the target region. The magnetic fields operate at different frequencies and thus produce a beat frequency signal where the electric fields intersect. The frequencies are chosen so a time-varying electric field, or a current induced by a time-varying magnetic field, alternating at the beat frequency would stimulate excitable tissue located in the target region. Some embodiments utilize a novel coil, which includes a first conductor and at least one second conductor electrically connected to the first conductor at a point. The second conductor extends from the point of connection with the first conductor to a location spaced from the first conductor. At least a portion of the second conductor adjacent the point of connection with the first conductor is non-parallel to the first conductor.
