Title: Carbon monoxide detector
Inventor: ABROMAITIS ANDRE T

Granted: 1985-06-04
Abstract: ABSTRACT OF THE DISCLOSURE             A carbon monoxide detector comprises a single monochromatic infrared source which is arranged to alternately direct light through two separate gas-containing test chambers. The first chamber is supplied with gas to be tested which has an unknown carbon monoxide content.  A catalytic burning chamber is connected between the first and second chambers to receive gas from the first chamber, burn the carbon monoxide in the gas to carbon dioxide and supply the carbon monoxide free gas to the second chamber.  A single infrared light detector is provided for receiving light as it comes alternately from the two chambers.  The light from the two chambers is compared to determine the amount of carbon monoxide present in the gas of the first test chamber.  Since the same background gas is provided in both chambers and only a single infrared source and detector are utilized, inaccuracies due to dif-ferences in background detection, infrared source intensity and infrared detector sensitivity are overcome.

Abstract: ABSTRACT An automatic tracking system for an antenna device for satellite communications and using step tracking principles is disclosed which repeatedly effects tracking at predetermined intervals so that the receive electric field from the satellite becomes maximum.  When a platform loaded with an antenna device for satellite communications is caused to sway to an inclined position during an interval between sequential tracking operations, sensors senses a pitching angle and a rolling angle of the platform.  The outputs of the sensors are compared with an angle previously stored as an inclination angle of the platform which existed just before interval between sequential tracking operations.  If the difference is larger than a predetermined value, step tracking is resumed to track the satellite even in a suspension period of step tracking.

Abstract: RADIO CIRCUIT   Abstract A system and method for adjusting the frequency of operation of a radio frequency circuit including an inductive loop having an ad-justable exposed inductor portion is provided.  The frequency of operation of the circuit is first detected with means for detecting a parameter relating to and representing the frequency of operation. The adjustable inductor portion is associated with a selectively movable actuator device coupled to the frequency detecting means and a source of signals representing a predetermined frequency of oper-ation for the circuit.  A control circuit means, preferrably a com-puter, is coupled to the detecting means and to the source of sig-nals to provide an output control signal when the detected fre-quency of operation bears a predetermined relationship to the pre-determined frequency of operation.  The control signal operates the actuator device to adjust the configuration of the exposed inductor portion by moving the actuator device whereby the inductance of the inductive loop and the frequency of operation are associatively varied.  The configuration of the inductor portion is fixed at a position of adjustment determining the frequency of operation to be at the predetermined frequency.

Abstract: ABSTRACT        An eraser used for an electronic blackboard.  It is intended to provide an eraser in which the erasing area is variable according to the size and accuracy of the figure to be erased.   The eraser is composed of a main unit carrying a small area erasing unit, and a large area erasing unit which is detach-ably engaged to the main unit.  Detectors installed in the main unit detect when the eraser is touched on the surface of the board, and/or that the large area erasing unit is used, and sends a signal to the system controller.  When the system controller receives the signal, it deletes the memory corresponding to the area covered by the erasing units and erases the corresponding area of the figures displayed on the display unit.

Abstract: Astract Load cells incorporating one or more gaged beams as the load sensing elements are compensated for off-center loading in the longitudinal and/or lateral direc-tions.  The load cell may also include one or more flex-ure arms extending parallel to the beam.  The relative position of the gages and the neutral axis of the beam is made such that the gages produce a correctible re-sponse to off-set loading by positioning the gages and/or physically altering the beam.  Preferably, conventional or special strain gages are mounted upon the beam(s) to produce a correctible response by the gages by rotating and/or displacing them with respect to the longitudinal axis of the beam.  Resistors are then connected to cer-tain of the strain gages to compensate for off-center loading.  The strain gages are advantageously placed all on one side of a beam but may be placed on opposite sides thereof.

Abstract: ABSTRACT     A method and system for scrambled transmission of an information signal having a regular, repeating information rate from which a receiver of the information signal derives synchronizing information as in a television video signal.  The information signal is summed with a scrambling signal having a frequency which is a function of the information rate plus an error quantity within a predetermined bandwidth, namely that of the synchronizing circuitry in the normal information receiver.          The sum of the information signal and the scrambling signal is transmitted as the scrambled information signal.  In a television scrambling system, the  information signal is a television video signal and the information rate is a video synchronizing rate, preferably the horizontal line rate.  The television information signal also includes an audio signal which is scrambled by mixing the audio signal with a carrier signal related to the video synchronizing rate, to produce a lower sideband which is transmitted as the television audio signal.          The frequency of the scrambling signal Fj is defined by the equation Fj = A?Fh + B, where A is an integer, B is the value error quantity, and Fh is the information rate.  To increase scrambling security, the frequency of the scrambling signal may be modified periodically.  Also disclosed is a method and system for decoding or unscrambling the scrambled information signal.

Abstract: ABSTRACT OF THE DISCLOSURE A voice synthesizing system for synthesizing a voice from voice parameters containing acoustic parameters which express vocal tract transmission characteristics and voice source parameters which express the intensity and type of a sound source and from pitch information as described.  The synthesizer includes a voice parameter input for supplying the voice parameters for predetermined frames and a non-voice parameter generator for generating parameters to synthesize a non-voice sound.  An internal status detector receives connecting data containing the number of non-voice frames, the number of voice parameter frames and the number of parameter interpolation frames and counts each of the numbers to detect the internal status of the synthesizer.  A parameter selector selects either an output from the voice parameter input or an output from the non-voice parameter generator in response to an output from the internal status detector.  A parameter interpolator interpolates an output from the parameter selector in response to the output of the internal status detector.  A pitch interpolator performs the interpolation of a pitch on the basis of pitch information having a pitch value at an arbitrary point and its interpolation period.  A voice is synthesized in response to the output of the parameter interpolator and pitch interpolator.
