Abstract: Purifying target biomolecules, such as nucleic acids or proteins, from a biological source is a time intensive process and is typically performed by a skilled technician or scientist owing to the highly technical nature of the work. Systems, devices, and methods disclosed herein enable the automated bioprocessing and purification of target biomolecules from a biological source. For example, an instrument and disposable cartridge are provided for automatedly isolating and purifying nucleic acids (such as plasmid DNA from a bacterial culture) or for isolating protein from any biological sample. Such an exemplary instrument and cartridge can work in concert to timely release, mix, and move the target biomolecule and various reagents and buffers through a target biomolecule purification process, resulting in a purified target biomolecule with less manual oversight than traditional approaches.

Abstract: An audio speaker has at least one transducer for converting electrical signals into mechanical motion. There is a planar sound producing structure that has a first face and a second face. A mechanical connection connects the at least one transducer to the sound producing structure, such that mechanical motion produced by the at least one transducer induces the sound producing structure to vibrate and produces sound from the first face and the second face. A deflector is interposed between the at least one transducer and the sound producing structure. The deflector is adjacent to the second face of the sound producing structure and reflects the produced sound from the second face of the sound producing structure to a listening area forward of the first face.

Abstract: A technique for qualification of loops for new digital subscriber line services (DSL) involves use of an expert system, such as a neural network. A database of loop characteristic information and performance data enables the expert system to train or learn how to predict performance for future loops. In response to data characterizing a new loop to be qualified, the trained expert system predicts digital subscriber line performance for the new loop. Typically, the prediction enables classification of service capacity for the new loop into one of several classes corresponding to levels of DSL service offered through the network. The database for use by the expert system is updated as each newly qualified loop is brought into service and actual performance for that loop is known.

Abstract: A system and method for providing telephone type services over the internetwork commonly known as the Internet. Wireless digital telephones in communication with wireless digital communications systems have speech coders that generate digital voice samples, and encoders that encode the digital voice samples to minimize bit errors during RF transmission. The wireless digital communications system demodulates the received modulated wireless signal transmitted by the digital telephone to recover the encoded, digital voice samples. The error correction codes within the encoded, digital voice samples are removed to recover the original digital voice samples generated by the vocoder in the digital telephone.

Abstract: The present invention involves a transmission of a known signal over a line intended for a digital subscriber line (xDSL) service, measurement of a resulting waveform received through the line and processing of the received signal to derive a set of eigenvalues characterizing the transfer function of the line. In the preferred embodiment, a transmitter applies a known test signal waveform to the transmission line. The test signal corresponds to a desired one of several available xDSL services. At the receiving end of the line, the output signal from the line is sampled, to capture a digitized sample waveform for the received signal. A computer processes the captured waveform to determine eigenvalues characterizing the transfer function of the line with respect to the one service. If the eignevalues for the line bear predetermined relationships to threshold values, indicating acceptable line transfer function for the desired xDSL service, then the invention certifies the tested line for use on that service.

Abstract: A wireless, cellular radio link is provided from a base station to a plurality of subscriber stations within a cell reception area. Information data, which may be of textual, video or other format, are communicated asymmetrically as high bandwidth transmissions in the downstream direction to the users while low upstream bandwidth is provided to permit users to request the data or to provide return radio link condition information. Buffers associated with respective subscribers collect requested data from information providers for transmission by the base station in a statistical time division multiplexed (STDM) fashion, whereby each subscriber may be assigned a minimum transmission time interval during which data will be transferred from the associated buffer. Controlled logical token passing governs a variable token interval during which data transmission for each buffer is permitted in turn.

Abstract: A statistical time division multiplexer facilitates distribution of data from various sources through a wireless transmission system to a plurality of subscriber stations within a cell reception area. Controlled logical token passing governs a variable token interval for data transmission from each buffer, associated in a base station with a respective receiving subscriber station, in turn to form a common data stream. Each subscriber may be assigned a minimum transmission time interval during which data, if present in the associated buffer, will be transferred. Data may be fed from the buffers in successive time intervals at bit rates that can vary from interval to interval. Variations of data transmission rate and token interval for each subscriber can be separately controlled on the basis of both presubscribed levels and current quality of service levels of the radio link. Channel quality and/or bit error rate for each channel may be fed back dynamically from the user for each token interval.

Abstract: An arrangement (apparatus and method) for providing a code division multiple access (CDMA) transmission system in an urban environment using spatially-diverse antennas and time-diversity devices and techniques to provide improved cell coverage without the detrimental effects of multipath (Rayleigh) fading. The spatially-diverse antennas output identical CDMA-modulated signals to a serving area at different times, whereby each CDMA-modulated signal output from a corresponding antenna has a sufficent delay to avoid mutual interference with the identical CDMA-modulated signals output from other antennas. The delay assigned to each antenna is within a range greater than a chip interval, and less than or equal to a base station sequence offset between base stations. As a result, a subscriber station is able to separately demodulate the received CDMA-modulated signals from the different antennas as CDMA signals having adequate multipath delay for demodulation using a rake receiver.

Abstract: A cellular system for distributing a plurality of television programs in a desired service area. A plurality of groups of spaced transmitting antennas are disposed substantially on the peripheries of adjacent cells disposed in the service area. The antennas are directional and directed to propagate substantially simulcast signals into the cell with which the antenna is associated so that the propagation patterns of the transmitting antennas associated with the cell overlaps over substantially a major portion of the area enclosed within the cell. Antennas disposed substantially on the peripheries of adjacent cells propagate directional signals into each of the adjacent cells. In a broadcast version the frequencies of the signals transmitted by all of the antennas are the same. In a dedicated service version the frequencies of the signals transmitted into adjacent cells are different.
