Abstract: Pseudo-differential drivers and receivers are used to communicate data signals between two or more IC chips. The data paths are aligned using programmable delay circuitry to de-skew each data path. A programmable reference generator is used to generate a reference voltage used by one or a group of receivers to detect the data signals. The reference voltage is adjustable using coarse as well as fine digitally controlled voltage increments. Test signals are sent from the driver to the receiver and the reference voltage is varied over its adjustable range using the coarse and fine adjustment controls while circuitry determines a measure of the detection timing jitter on successive transitions of the test signal. The operational value of the reference voltage is set to the value where the detection timing jitter is determined to be a minimum.

Abstract: Server-side determination of quality of service received by a client. Content is transmitted from the server to the client according to a protocol. During transmission, the protocol requires the client to periodically send the server statistics concerning the transmitting, e.g., lost packets, latency, or the like. The server simulates the network connection between the client and server based at least in part on the received statistics. The simulating allows the server to recreate, server-side, the content received by the client. The server may then compare what was sent to the client, versus the recreated received content, to determine a quality of service received by the client.

Abstract: Circuitry used to de-skew data channels coupling parallel data signals over a communication link employs SOI circuitry that is subject to generating pulse distortion due to the history effect modifying threshold voltages. To substantially eliminate the pulse distortion, data signals are XOR with a repeating scramble data pattern that generates scrambled data with a minimum average ratio of logic ones to logic zeros logic zeros to logic ones. The scrambled data is sent over the communication link and de-skewed in the SOI circuitry with little or no pulse distortion. The scramble data pattern is again generated at the receiver side of the communication link after a delay time to synchronize the logic states of the scramble data pattern that generated the scrambled data with the scrambled data at the receiver side. The delayed scrambled data pattern is again XOR'ed with the scrambled data to recover the data signal.

Abstract: A refrigerated cold beverage merchandiser (10) includes an enclosure defining an insulated, refrigerated display cabinet (25) and a compartment (30) heat insulated therefrom wherein a compressor (40) a condenser (50) and a condenser fan (60) are disposed. The condenser (50) is formed by a plurality of in-line tube banks (52). Each tube bank (52) is a serpentine tube formed a plurality of unfinned, straight tube segments (54) extending in parallel rows (55) between a pair of spaced, opposed end plates (58) and elbow turns (56) connecting neighboring straight tube segments (56) in a conventional manner. Each successive tube bank (52) is arranged with the other tube banks so that respective parallel tube rows (55) are disposed in-line from the front to the rear of the condenser (50) or with each successive tube bank being offset in a slightly staggered arrangement.

Abstract: A method for evaluating an end-user's subjective assessment of streaming media quality includes obtaining reference data characterizing the media stream, and obtaining altered data characterizing the media stream after the media stream has traversed a channel that includes a network. An objective measure of the QOS of the media stream is then determined by comparing the reference data and the altered data.

Abstract: Delay circuits have programmable delay elements to delay data signals so a clock samples the data signals in the middle of the eye window pattern. The clock is frequency divided by two, generating a divided clock coupled to a clock delay circuit and a data delay circuit generating a toggle clock and a delayed toggle clock that are sampled with the clock signal. A state machine varies the number N of delay elements selected in the data delay circuit until successive samples of the toggle clock and the delay toggle clock have opposite logic stages. The resulting number N is the number of delay elements required to generate a delay equal to one period of the clock. The delay of each delay element is adjusted using adjustment control signals until an N is generated that is within a predetermined range. The adjustment control signals are distributed to the data delay circuits.
