Abstract: A method and apparatus for establishing a non-standard data rate in a wireless communication system include processing that begins by establishing a standard specified data rate for a given transmission. The processing then continues by determining whether the data rate of the transmission can be adjusted from the standard specified data rate by a non-standard data rate adjustment. The processing then continues when the data rate can be adjusted, adjusting the data rate to a non-standard data rate for the given data transmission.

Abstract: A low power radio transmitter includes an intermediate frequency stage, signal-to-pulse conversion module, and a power amplifier. The intermediate frequency stage up-converts the frequency of a base-band digital signal into an N-bit signal at the intermediate frequency. The signal-to-pulse conversion module converts the N-bit signal at the intermediate frequency into a pulse signal of M-bits at the radio frequency. As such, the signal-to-pulse conversion module is taking an N-bit signal (e.g., an 8-bit digital signal) and converting it into an M-bit pulse signal (e.g., a 1-bit pulse stream). Accordingly, the M-bit signal at the radio frequency is essentially a square-wave, which has a peak to average ratio of zero, is subsequently amplified by the power amplifier.

Abstract: An agent may be coupled to receive a clock signal associated with the bus, and may be configured to drive a signal responsive to a first edge (rising or falling) of the clock signal and to sample signals responsive to the second edge. The sampled signals may be evaluated to allow for the driving of a signal on the next occurring first edge of the clock signal. By using the first edge to drive signals and the second edge to sample signals, the amount of time dedicated for signal propagation may be one half clock cycle. Bandwidth and/or latency may be positively influenced. In some embodiments, protocols which may require multiple clock cycles on other buses may be completed in fewer clock cycles. For example, certain protocols which may require two clock cycles may be completed in one clock cycle. In one specific implementation, for example, arbitration may be completed in one clock cycle. Request signals may be driven responsive to the first edge of the clock signal and sampled responsive to the second edge.

Abstract: Close two constituent trellis of a turbo encoder within the interleave block. The state of a multi-state encoder is forced to a known/predetermined state at the end and beginning of each data frame. Packet based and/or frame based data transmissions benefit greatly when the encoder state of a multi-state encoder is known at the beginning and end of each frame. Appropriately chosen symbols, selected to force the encoder to a known state at the end of a data frame, may be padded to the end of a data frame that is to be encoded; this will force the encoder to “close” at the end of the data frame. These closure symbols may also be padded to the end of the data frame before the data frame in interleaved. Moreover, within encoder embodiments that include multiple constituent encoders, both constituent encoders will be forced to the known/predetermined state.

Abstract: A digital-to-analog converter (DAC) disposed in a data transmission path to convert data from a digital format to an analog format to be transmitted is powered down during a receive mode of operation for a wireless communication device. Likewise, an analog-to-digital converter (ADC) disposed in a data reception path to convert received data from an analog format to a digital format is powered down during a transmit mode of operation.

Abstract: A wireless transceiver includes a Radio Frequency (RF) transceiver, a baseband transmitter section, and a baseband receiver section. The baseband receiver section receives a baseband signal from the RF transceiver, extracts data therefrom, and provides the data to a host system. The baseband receiver section includes a programmable gain amplifier, an Analog-to-Digital Converter (ADC), a symbol timing compensation section, an RF carrier compensation section, a decision feedback equalizer section, and a preamble processor. The symbol timing compensation section modifies the samples of the baseband signal to compensate for symbol timing variations between a symbol clock of the wireless device and a symbol clock of a transmitting wireless device. The RF carrier compensation section modifies the samples of the baseband signal to compensate for RF carrier variations between an RF carrier of the wireless device and an RF carrier of the transmitting wireless device.

Abstract: An empty cartridge removing device of a dummy launcher for animal training having a fixed member of a fixed assembly pivotally assembled with a body of a firing assembly, the empty cartridge removing device comprising: a barrel adapted to be coupled with a coupling hole of the fixed member of the fixed assembly and having a guide projection extended therefrom, and an empty cartridge removing assembly for mating with the guide projection of the barrel therein such that a blank cartridge is partially setback from the end of the coupling hole of the barrel. When the cartridge is fired, the cartridge expands to the inside diameter of the coupling hole and the empty cartridge removing assembly. With the empty cartridge partially setback, the mechanical advantage of the empty cartridge removing assembly allows the empty cartridge to be easily removed from the dummy launcher.

Abstract: A system includes a bus and a circuit for precharging the bus. The circuit may be coupled to receive a clock signal associated with the bus, and may be configured to precharge a bus during an interval of the period of the clock signal, the interval being between a first edge (rising or falling) and the subsequent edge (falling or rising). A second interval within the period and excluding the interval may be used to perform a bus transfer. In this manner, both precharging and transfer may be performed in the same clock cycle. Bandwidth of the bus may be improved since transfers may occur each clock cycle, rather than having a non-transfer clock cycle for precharging.

Abstract: A pulse frequency modulation unit controls upper limit level and lower limit level for an output voltage of a DC-DC converter. A voltage mode control loop uses the upper and lower limit levels in a feedback loop to generate a control signal to enable and disable the converter circuit.

Abstract: A method for servicing high-speed data communications in a cellular wireless communication system includes the wireless transmission of data at a higher data rate than is supportable considering constraints of the prior art. The cellular wireless communication system determines a supportable data rate for a wireless subscriber unit based upon available base station transmit power resources and other resources. A data rate multiplier is then determined that is greater than 1 and will typically have a value of 2, 4, 6, 8, . . . , N, wherein N is an integer. With the data rate multiplier determined, a serviced data rate for the transmissions to the wireless subscriber unit is equal to the supportable data rate times the data rate multiplier, i.e., serviced data rate=N * supportable data rate, such that the serviced data rate is a multiple of the supportable data rate. Data is then transmitted from the base station to the wireless subscriber unit at the serviced data rate.

Abstract: A system may include two or more agents, one of which may be identified as a default agent. If none of the agents arbitrate for the bus, the default agent may be given a default grant of the bus. If the default agent has information to transfer on the bus, the default agent may take the default grant and my transfer the information without first arbitrating for the bus and winning the arbitration. In one embodiment, the default agent may arbitrate for the bus when it has information to transfer and no default grant is received. The default agent may be an equal participant in arbitration. A fair arbitration scheme may thus be implemented in arbitrations in which there is contention for the bus.

Abstract: A Radio Frequency (RF) circuit includes an active portion and a tuned portion. The active portion receives an RF signal and that operates upon the RF signal. The tuned portion couples to the active portion and includes a first inductor, a second inductor, and an NMOS transistor. The NMOS transistor has a gate, a drain, a source, and a body. The drain and source operably couple/decouple the second inductor to/from the first inductor. The drain and source are biased at respective operating voltages (greater than ground and less than a first voltage supply) by the active portion and the tuning portion. The body couples to a first voltage supply, via a control circuit or switch in some cases. Applying a second voltage supply (that is greater than the first voltage supply) to the gate turns ON the NMOS transistor.

Abstract: A valid signal may be detected by initializing gain settings of the receiver section. The processing then continues by measuring received signal strength of a signal received by the receiver section to produce a 1st received signal strength indication (RSSI). The processing continues by adjusting the gain setting of the receiver section such that the 1st received signal strength indication is a predetermined offset less than a signal strength threshold. The process then continues by measuring the received signal strength of the gain adjusted representation of the signal to produce a 2nd received signal strength indication. The processing continues by appending a 2nd offset to the 2nd received signal strength value to produce an adjusted received signal strength indication value when the 2nd received signal strength value drifts from the signal strength threshold less the predetermined offset.

Abstract: A drill bit assembly is formed to drill into an object while reliably conducting a fluid onto a point being drilled and subsequently into the object being drilled includes a sleeve that is bored and threaded and cut flush to substantially mate with the outside surface of a conducting tube. An elbow connector is mounted within the sleeve and receives a fluid from a tube coupled thereto. The drill bit assembly further includes a telescoping conduction tube for conducting fluid about the drill bit as it rotates and into an opening created by the drill bit. The telescoping conduction tube axially slides about the conduction tube and also conducts fluid about the drill bit while slidingly mating with the conduction tube to minimally leak the fluid.

Abstract: To adjust transmit power of a DSL modem, an estimated electrical length of a loop is first determined when a 1st DSL modem at a 1st location transmits a plurality of signals to a 2nd DSL modem at a 2nd location. Each of the signals transmitted by the 1st DSL modem have a known frequency and are transmitted at a known power level. Upon receiving the signals, the 2nd DSL modem determines the received power level for each of the signals. The 2nd DSL modem then estimates an electrical length of a loop between the 1st and 2nd DSL modems for each of the signals received. The 2nd DSL modem then processes a plurality of estimated electrical lengths in accordance with a function to produce a determined electrical length. Having determined the electrical length, the 2nd DSL modem adjusts its transmit power accordingly.

Abstract: A method of presenting a selected portion of graphical images within a wireless terminal that includes receiving an original graphical image, having a source resolution, to be presented on a display screen. The native pixel resolution of the display screen may differ from that of the original graphical image. A complex decimation pattern when applied to the selected portion of the image allows the selected portion of the original graphical image to be resized from the source resolution to a decimated resolution operable to be displayed within the native resolution of the display screen. Decimated pixels need not be further processed to reduce the processing requirements imposed on the system processor. Operations normally associated with the decimated portions of the image may be offloaded from the processing module to improve system efficiency.
