Abstract: An electronic device includes a medium access controller (MAC) to generate frames and transmitter circuitry to convert the frames to radio-frequency (RF) analog signals for transmission. The MAC is to initiate frame generation at a time that precedes initiation of RF analog signal transmission by a specified time period. In a first mode, the MAC is to generate a dummy frame during a first portion of the specified time period and to initiate generation of a transmit frame during a subsequent second portion of the specified time period. Also in the first mode, the transmitter circuitry is to convert the dummy frame into a first analog signal, discard the first analog signal, convert the transmit frame into a second analog signal, and transmit the second analog signal.

The vibrator is fixed to the end of a tube which extends into the hopper through a hole in the hopper wall. A rubber isolator molded on the tube is clamped between flanges one of which is welded to the outer surface of the hopper wall.

Abstract: A guide shoe for a shearer loader, in particular for a shearer-loader drive assembly, comprising at least one base wall, comprising a guide projection, on the base-wall side, for engaging under a rack drive of a rack drive arrangement, and comprising a guide surface for engaging behind the rack drive. To achieve shorter downtime periods in the case of repairs to the shearer-loader drive assembly due to wear, and in order to reduce their susceptibility to wear, the guide projection and the guide surface are realized on wear inserts that are movably and, preferably, replaceably fastened, or fastenable, to the guide shoe. Movement of the wear inserts could be limited by pivot limiting strips or inhibited by clamping strips.

Abstract: A dual band radio is constructed using a primary and secondary transceiver. The primary transceiver is a complete radio that is operational in a stand alone configuration. The secondary transceiver is a not a complete radio and is configured to re-use components such as fine gain control and fine frequency stepping of the primary transceiver to produce operational frequencies of the secondary transceiver. The primary transceiver acts like an intermediate frequency device for the secondary transceiver. Switches are utilized to divert signals to/from the primary transceiver from/to the secondary transceiver. The switches are also configured to act as gain control devices. Antennas are selected using either wideband or narrowband antenna switches that are configured as a diode bridge having high impedance at operational frequencies on control lines that bias the diodes.

Abstract: A Viterbi decoding system interprets bits in received QAM constellations as many-valued parameters rather than binary valued parameters. It performs the Viterbi algorithm using these many-valued parameters to provide results superior to hard decision decoding. Rather than applying a hard 0-1 function to the QAM data, the system uses a non-stepped linear or curved transfer function to assign values to the bits. In another aspect, a system differentiates between data bits based on their estimated reliability, giving more emphasis to decoding reliable bits than unreliable bits using any of a variety of techniques. By differentiating between god and bad bits and de-emphasizing or ignoring unreliable bits, the system can provide a significant reduction in uncorrectable errors and packet loss.

The upper frame members extend upwardly and in a radially outward direction from the stationary hubs, and the base frame members extend downwardly and in a radially outward direction from the stationary hubs to engage a support surface. The one or more resilient members have a resiliency that allows a child within the apparatus to bounce vertically relative to the support surface in response to the child pushing its legs against the support surface.
