Abstract: The invention is directed to an inflatable display that has a plurality of inflatable compartments. A first inflatable compartment is continuously inflated by a first fan element and at least a second inflatable compartment is periodically inflated by a second fan element. The inflatable display may be produced from permeable material and configured to represent a predetermined shape or design when inflated, such as a witch and caldron, Santa Claus and a chimney, or the Easter Bunny and an Easter egg. Further, the inflatable display may include a string of lights enclosed within a plastic shell to avoid damaging the inflatable display material by heat or fire. Also, the period associated with the operational inflation/deflation may be controlled by a variable controller connected to the second fan element.

Abstract: A DSSS system determines transmission reliability of a communication channel in real time. A DSSS transmitter (f0=1/T) generates a Pseudo Noise (PN) code and modulates a carrier source [cos. (2??c)] with a selected chip rate. The transmitter bandwidth is a direct function of the chip rate. The PN coded carrier signal is further modulated by a data signal [m(t)] to provide an output signal [s(t)] to a correlator via a communication channel for purposes of determining the transmission characteristic of the channel. The correlator running a variable length pseudo noise code combines the code and the carrier which relates the incoming data signal to a correlation value for detecting the data signal. The correlation value is compared to a threshold value based upon experience of reliable transmission of data through the communication channel.

Abstract: A receiver may be adapted to prevent overflow or underflow of its data storage by generating a transmit rate value as a feedback to the sender. Speed adjustments are performed periodically with a fixed time period denoted by Dt. Transmission rates are explicitly 0, Max/2, and Max. The receiver queue is itself drained at a rate R that at any time satisfies 0<=R<=Max. The level of occupancy of the receiver storage queue is denoted by Q. The maximum capacity of the receiving queue is designated Qmax, so at any time, 0<=Q<=Qmax. Two thresholds T1 and T2 (with 0<T1<T2<Qmax) of levels of the receiver queue value Q are determined. A transmit rate is then determined by the level of the receiver queue Q compared to the thresholds. The transmit rate feedback value achieves the desired goal of avoiding overflow and, once the value of Q has been positive at least once, avoiding underflow.

Abstract: This invention prevents defects generated when a bonded substrate stack having a separation layer is separated. A bonded substrate stack (101) having a porous layer (101b) is separated in two steps of the first and second processes. In the first process, a jet is ejected to the porous layer (101b) while rotating the bonded substrate stack (101) to partially separate the bonded substrate stack (101) while leaving the central portion of the porous layer (101b) as an unseparated region. In the second process, the jet is ejected to the porous layer (101b) while rotation of the bonded substrate stack (101) is stopped. A force is applied to the unseparated region from a predetermined direction to completely separate the bonded substrate stack (101). Also, the first region (peripheral portion) and second region (central portion) of the bonded substrate stack (101) having the porous layer (101b) are separated using a jet and ultrasonic wave, respectively.

Abstract: A multi-master computer system having overlapped read and write signal with scalable address pipelining programmable increases the depth of address pipelining independently on two overlapped read and write data busses up to “N” deep requests. The system includes a local bus having an address bus, a read bus, and a write bus. Master devices are coupled to separate address, read data and write data buses. Slave devices are attached to the data busses through shared, but decoupled address, read and write data buses. An arbiter is coupled to the data bus and allows masters to compete for bus ownership. The arbiter includes read and write pipeline logic for processing and priortizing master and slave read and write data transfers across the data bus.

Abstract: Signals are evenly distributed and transmitted using a plurality of channels. Multicast and broadcast communications are efficiently made. Signals from each sub transmission paths are distributed onto a plurality of channels to send them via these channels. Furthermore, signals are inserted into the channels by finding empty packets from the channels, thus allowing input of signals to the channels that transfer various kinds of signals. Upon multicast or broadcast communications, an input signal is copied in correspondence with a plurality of channels.

Abstract: A WCDMA system includes a Base Station (BS) transmitter, or forward transmitter and a pilot channel that transmits control signals between the BS and a Mobile Station (MS) to reconfigure their transmitter/receiver. Reconfiguration is performed according to the prediction of the channel attenuation and the threshold set at the BS or MS based on its channel power probability density function separated into three distinct equal probable regions. In one embodiment, Seamless Rate Change (SRC)/Transmitter Power Control (TPC) logic uses the predicted channel attenuation to signal both the transmitter and the receiver in a channel to reconfigure their transmit power level according to the power density function (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.

Abstract: Two image signals from a non-interlace scanning type CCD at predetermined horizontal and vertical sampling frequencies are respectively inputted to automatic gain controllers, then to a color separator where the input signals are separated into luminance signal and color difference signals. The luminance signal is processed by a two-dimensional filter which traps frequency components having ½ of the horizontal and vertical sampling frequencies. Accordingly, a variation in amplification characteristics of the automatic gain controllers is compensated as a variation of luminance signals having Nyquist frequencies in the horizontal and vertical directions. Thereby, bad effect due to variations in amplification characteristics of the automatic gain controllers is reduced even through two output signals from the non-interlace scanning type CCD are processed by the respective automatic gain controllers.

Abstract: An aluminum based header plate, for a tubular heat exchanger for a motor vehicle, has an external coating on its outer face. An end portion of each heat exchanger tube is received in a corresponding through hole in the header plate. The tube end portions have a predetermined cross section and an external coating, and secured to the header plate by brazing. Each through hole is made by a slitting operation followed by configuration of the through hole within a selected zone of the header plate, this zone being press-formed so as to form in the outer face of the header plate a collar portion in that zone. The internal transverse cross section of each collar portion is substantially identical to the predetermined cross section of the corresponding tube end portion. After the tube has been introduced into the through hole, which extends through the collar portion, there is surface contact between the respective external coatings of the collar portion and of the tube end portion.

Abstract: A spacer-connector stud comprises a stacked array of glass epoxy laminates, each laminate having a copper layer laminated thereto. The top and bottom laminates of the stud include a spatial array of thermal contacts suitable as a footprint for C4 bump technology. A location is selected on a circuitized base card to accommodate the laminated stud. The stud has a thickness greater than twice the thickness of the components attached to the card. The thermal contacts on the stud, typically solderable, join to a wiring array on the card. A second multi-chip module card having attached and interconnected components on both sides of the second card is mechanically aligned with the based card and pressed against the contacts on the top layer of the stud to form an assembly. The assembly is heated causing the second card to become soldered to the contact footprint on the stud.
