Title: Sampler for a picture display device
Inventor: VAN ASMA CORNELIS G M
IPC: G09G3/36
Filed: 2000-02-16
Granted: 2003-03-11
Abstract: The invention relates to a sampler (2) and a method for converting a signal (S1) into a multiple signal (S20 ... S22), comprising a stage (20) of track and hold circuits (210 ... 212, 220 ... 222). The stage (20) is divided in to sub-stages (21, 22) with the same number of track and hold circuits (210 ... 212, 220 ... 222). The sub-stages (21, 22) are connected to the output of the sampler (2) in a successive and cyclic way by use of a switch (23). This means that the signal at the output (S20 ... S22) remains stable during the time when the next sub-stage tracks and holds the signal (S1). In a preferred embodiment the stage (20) comprises two sub-stages (21, 22). The multiple signal (S20 ... S22) is generally stable for a number of clock periods, which number is equal to the number of track and hold circuits (210 ... 212, 220 ... 222) per stage (21, 22). The resulting, more compact design is very suitable for integration, and the power consumption can be kept low. The arrangement requires less buffering, which makes it simpler to avoid uniformity problems and ghost images.

Title: Adaptive power control in wideband CDMA cellular systems (WCDMA) and methods of operation
Inventor: SADRI ALI S
IPC: H04B1/707
Filed: 2000-07-26
Granted: 2002-01-11
Abstract: A WCDMA system includes a base station (BS) transmitter, or forward transmitter and a pilot channel that transmits control signals between a BS and a mobile station (MS) to reconfigure their transmitter/receiver. This reconfiguration is performed according to the prediction of the channel power and the threshold set at the BS or MS based on its channel power probability density function separated into three distinct equal probable regions. Data signals are encoded using a one-half Viterbi encoder and interleaved. The interleaved data bits are modulated using quadrature phase shift keying (QPSK) modulation. The QPSK data is multiplexed with the pilot channel and spread by an appropriate code in an OFDM transmitter modified by a long code. Output of the transmitter may be provided to two diverse antennas for reliable communications to the receiver. Data may be received at two diverse antennas. The outputs are provided to match filters coupled to a coherent rake receiver and a channel prediction system. The future attenuation of the channel coefficients and power are determined by the prediction system for several milliseconds. In one embodiment seamless rate change (SRC/transmitter power control (TPC) logic uses the predicted channel power to signal both the transmitter and the receiver to reconfigure their transmit power level according to the pdf of the channel power and threshold level. A transmission rate is reduced when the power level is below the threshold and increased when the channel power is above threshold. The pilot channel is used to signal the mobile station and the base station. In another embodiment, transmission power control bits are entered into transmit slots according to the above scheme and thresholds. When the predicted channel power falls below the threshold, the BS or the MS increase transmit power by a predetermined level. When the predicted channel power is above the threshold, a predetermined level reduces the transmitter power. In still another embodiment, the BS or MS transmits the predicted channel power of the two diverse antennas to the remote side. MS or BS compares the power of the two channels with a threshold and selects the antenna that propagates through the better channel which reduces MAI and ISI. The three embodiments aid a WCDMA system in maintaining conductivity, maximizing throughput, and minimizing mobile station power consumption by adjusting transmit power, seamless rate change and transmit antenna diversity.

Granted: 2002-08-11
Abstract: The present invention relates to a fork lift comprising a traverse system for traverse travel. During ordinary travel of the fork lift, when a direction change cylinder (51) is actuated by an orbit roll (58) by turning a steering wheel (16) right and left, both rear wheels transverse travel cylinders (53), which are in a predetermined inoperative position, perform the function of a link, so that the rear wheels (4) can be turned for direction change in response to the operation of the steering wheel. When the direction change cylinder is actuated to the limit, the right and left rear wheels can be turned for direction change into an inclined state with their rear ends approaching each other, thereby making it possible to make a pivot turn. The front and rear wheel turning devices (30, 50) are actuated to turn the front wheels (3) and rear wheels around vertical axes (27, 49) for direction change by 90 degrees (directed exactly sideways). At this time, in the rear wheel turning device, with the direction change cylinder put in the neutral position, the rear wheel transverse travel cylinders (53) are actuated to turn the rear wheels for direction change by 90 degrees. After the front wheels and rear wheels have been turned for direction change so that they are directed exactly sideways, the front wheels are driven forward and backward by the travel driving device (21); thus, the forklift (1) can be transversely moved to the right or left. Despite the 4-wheel type, direction change during the ordinary travel and during the transverse travel can be reliably made without requiring complicated electric control.
