Abstract: A method and apparatus (10) for determining the channel of a plurality of predetermined channels to which a remotely controlled receiver (12) is tuned. A viewer transmitter device (24) includes a keyboard (26) for receiving viewer entered selections and a remote transmitter which transmits infrared, ultra­sonic, radio frequency or other radiated control sig­nals for each of the viewer selections. A receiver device (28) in a channel detection system (10) receives a signal in the selected transmission medium, and immediately signals a jamming device (44) to broadcast interference which precludes the remotely controlled receiver (12) from identifying and acting upon the transmitted control signal. The receiver device (28) applies the received signal to a processor device (30) that performs a stored program to determine if the received signal corresponds to a transmitted con­trol signal from the viewer transmitter device (24) and, if so, to identify the channel to which the moni­tored remotely controlled receiver (12) is to be tuned. An associated memory device (52) is used for storing the identified channel reception data. The processor device (30) identifies the user selection and either applies a corresponding control signal to a second transmitter device (48) which transmits a control signal of sufficient strength to overcome the inter­ference, or instructs the jamming device (44) to cease the broadcasting of interfering signals. In either case, the remotely controlled receiver (12) will now receive and implement the viewer selection. The pro­cessor device (30) will periodically broadcast a com­mand to the remotely controlled receiver (12) contain­ing the last identified channel data to ensure that a viewer does not manually adjust the channel being viewed.

Abstract: A method and apparatus are provided for controlling the switching devices in a switched reluctance machine bridge inverter having at least two switching devices (35,38) per phase. One switching device (35) is used for hysteresis band current chopping to regulate phase current magnitude, while the other switching device (38), in combination with a flyback diode (47) provides a circulating path for phase current. Alternatively, current chopping and circulating are alternated between both switching devices during each conduction interval of the corresponding machine phase. Ripple current is decreased, thereby reducing the required size of the DC link capacitor. Switching losses are also reduced.

Abstract: Bidirectional lightwave transmission is restored and uniform amplification of lightwave signals over long spans of optical fiber is achieved by employing distributed amplification over the spans. Distributed amplification is achieved with an amplifying optical fiber which includes a long length of optical fiber having a dilute rare-earth dopant concentration substantially in the fiber core region, and a corresponding pump signal generator at at least one end of the doped fiber having the appropriate wavelength and power to cause amplification of optical signals by both Raman effects and stimulated emission from the rare-earth dopants. Dilute concentrations are understood as the range of concentrations substantially satisfying the condition that the gain from the rare-earth dopant, when near saturation, is substantially equal to the fiber loss.

Abstract: The transmitter in a power line communications system applies to the power line encoded logical-one and logical-zero bit signals consisting of signals formed respectively of predetermined different sequences of frequencies. The receiver, coupled to the power line, includes a first homodyne, non-coherent, quadratic demodulator for demodulating the logical-one bits and a second for demodulating the logical-zero bits. The first demodulator produces, locally, and in first and second channels, respectively, a first reference signal that is a replica of the logical-one bit sequence of frequencies and a second reference signal that is the replica in quadrature. The second demodulator produces, locally, and in third and fourth channels, respectively, corresponding third and fourth reference signals for the logical-zero bit sequence. Each of the four reference signals is applied to a corresponding analog multiplier for multiplication by the input signal in each channel. The output of each multiplier is applied to a low pass filter that passes only the dc component of the product signal which in turn is squared. The resultant signals in the first and second channels are summed to provide a first output signal, and the resultant signals in the third and fourth channels are summed to provide a second output signal. Compensation circuitry cancels error voltages developed in the demodulation channeis as a result of component offset, and the two output signals are integrated over a bit period and then compared to each other to detect a logical-one or logical-zero bit.

Abstract: A color cathode-ray tube apparatus comprising a video signal generator (14), a delay circuit (15), an electron gun assembly (6), a deflection yoke (7), a shadow mask (8), and a phosphor screen (2). The signal generator (14) generates three video signals simultaneously. The delay circuit delays (15) the first and second video signals with respect to the third video signal. The screen has phosphor elements regularly arranged. The electron gun assembly (6) generates three electron beams at different times, in response to the three signals output by the delay means (15). These beams are applied to the phosphor screen (2), and the phosphor elements of the screen emit red light, green light and blue light. Any three electron beams the gun assembly (6) emits simultaneously form three beam spots on the screen. These spots overlap for a distance longer than half the horizontal diameter of a beam spot formed by an electron beam of the greatest current which the gun assembly (6) can generate. The shadow mask (8), located between the phosphor screen (2) and the gun assembly (6), controls the beams, making them land at desired positions on the phosphor screen (2). The deflection yoke (7) deflects the beams in the horizontal and vertical directions, such that the electron beams scan the entire screen (2). The beams, deflected in the horizontal direction, land at substantially the same point on the screen (2), forming a color pixel thereon.

Abstract: In known blood analyzers, analysis is carried out on a serum sample. This sample is obtained from whole blood which has been spun in a centrifuge to separate it into at least two phases. Blood separation carried out in this way requires transferring the serum from one container to another prior to dispensing the serum sample on to a test element. Described herein is an improved analyzer (10) comprising an incubator (40) and a whole blood centrifuge (82), each using a separate rotor, and a serum dispensing station (20) positioned between them. A transfer mechanism (122, 124, 126, 128, 129, 130) is also included for moving a container from the centrifuge (82) to the serum dispensing station (20). The serum is then dispensed directly from the container on to a test element (E) which is then transferred to the incubator (40).

Abstract: An adaptive signal processor for use, for example, with stereo AM broadcast signals includes independent signal processing paths 108,113. Each path has a variable low-pass filter 105,110 and a matrix and variable Q 10 kHz notch filter 120,125 to form LEFT and RIGHT channel signals with a 10 kHz notched pass band determined by adjacent channel noise. A 10 kHz pass band signal VBF representative of adjacent channel noise from one of the signal processing paths 108,113 is compared to a reference VREF to generate a correction signal VC that is fed back to control the low-pass and notch filters 105-125. The correction signal VC adjusts the pass band and quality factor Q of the low-pass and notch filters 105-125 so that the effects of adjacent channel noise are minimized. Other receiver signals which are reflective of the quality of the received broadcast signal, e.g., the AGC signal, an excess modulation signal, and a receiver microprocessor signal are similarly employed to control the low-pass and notch filters 105-125.

Abstract: A historical control circuit in a thermal printer controls the drive current fed to a resistive heating element (2) according to the printing of previous dots by that resistive heating element (2). The circuit remembers whether or not the heating element (2) printed a certain number of preceding dots and, for each printed dot among those dots, masks an interval in the drive signal. This is done in such a way that if two patterns of previous dots contain unequal numbers of printed dots but generate equal residual temperatures, the drive signal for the pattern with more printed dots is divided into more separate pulses. Adjustments can be made by masking or unmasking a specific interval for a specific pattern. Cutoff of the drive signal may be delayed for patterns in which a certain number of most recent dots were all unprinted.

Abstract: A note-taking system based on a notepad computer with an integrated audio/video-recorder is described. A document is created or retrieved. As the user types on the keyboard or writes with the stylus or similar input instrument, each character or stroke that is input by the user is invisibly time-stamped by the computer. The audio/video stream is also continuously time-stamped during recording. To play a section of recording back, the user selects part of the note (perhaps by circling it with a stylus) and invokes a "playback selection" command. The computer then examines the time-stamp and "winds" the record to the corresponding place in the audio/video recording, where it starts playing - so that the user hears and/or sees what was being recorded at the instant the selected text or strokes were input. With a graphical user interface, the user may input key "topic" words and subsequently place check marks by the appropriate word as the conversation topic veers into that neighborhood.
