Abstract: Abstract of the disclosure:     For refining existing methods of measurement for the testing of the sealing of containers, the container tem-perature is measured during the detection of a pressure value which is employed for indicating leakage.  A limit pressure value, predetermined at a corresponding tempera-ture, for determining whether a container satisfies seal requirements is corrected in accordance with the actual measurement temperature, and then the actual pressure value and the limit pressure value at the same tempera-ture are compared.  In this way, pressure variations related from temperature changes are taken into account.

Abstract: This joint allows a drive member and a driven member of a transversely divided or separated vehicle to be deflected relative to each other about a virtual pivot axis which extends in a direction transversely to the vehicle. The drive member and the driven member are connected on each side by a first support element which supports against forces acting parallel to the transverse and vertical axes of the drive member and by a second support element which supports against traction and braking forces. Each first support element contains a support roll rotatably supported in a support at the driven member and guided in the longitudinal direction of the vehicle in a slide bracket arranged at the drive member. Each second support element comprises a hinged link rotatably mounted about a respective transverse axis at the drive member and the driven member. When travelling over changing slopes or gradients there results automatic matching of axle loads and torques at the drive wheel due to the deflection of the vehicle members.

Abstract: Computer Controlled Adaptive Speakerphone Abstract An improved switched-loss, adaptive speakerphone dynamically adjusts its switching thresholds and other performance parameters based on an analysis of acoustic environment and telephone line conditions. To access these conditions, the speakerphone utilizes a computer with sssociated firmware. As part of a calibration process, the speakerphone computes its thresholds before each use to compensate for possible variations in hardware circuitry therein. This is achieved by passing a first and then a second level of a test tone signal through the hardware circuitry and measuring the resulting response. The speakerphone also measures the acoustics of the room in which it operates as part of the calibration process. For this measurement, a tone burst signal is generated through a loudspeaker in the speakerphone and measured by a microphone also in the speakerphone. A time-domain acoustic response of the room is obtained which provides to the computer the amplitude of the return signal and the duration of its echo. The calibrationprocess is also applied to the speakerphone's interface to the telephone line through a hybrid. While in use, the degree of hybrid reflection is measured and the result provided to the computer. With the information on both the acoustic environment and the hybride the adaptive speakerphone is able to adjust on a real time basis the amount of switched loss and threshold switching levels between operating states to suit existing conditions. If, for example, the speakerphone is attached to a good telephone line and is in a good acoustic environment, it will provide the user with near full to full duplex performance.

Granted: 1998-06-23
Abstract: An improved video signal recording system for recording a full bandwidth video signal on a limited bandwidth medium is disclosed.  The recording system includes an encoder, coupled to an input terminal, for adaptively processing a composite video signal  in  response  to a motion  representative  signal,  and producing two signals; a luminance signal, having attenuated high frequencies subsampled so as to be folded into a spectral hole in the low frequencies,  and being bandwidth limited to the limited bandwidth of the recording medium, and a combined signal including a chrominance and a motion component.  Luminance signal recording circuitry records the folded luminance signal on the medium and chrominance signal recording circuitry records the combined chrominance and motion signal on the medium.       A n improved video signal playback system for reproducing such a prerecorded video signal is also disclosed.  They playback system consists of a luminance signal playback circuit for retrieving the  prerecorded  luminance  signal  from  the  medium,  and  a chrominance  signal  playback  circuit  for  retrieving  the prerecorded combined chrominance and motion signal  from the medium.  A decoder extracts the motion signal and the chrominance signal from the combined chrominance and motion signal and an unfolding circuit extracts the luminance high frequencies form the  prerecorded  folded  luminance  signal  and  adaptively regenerates the full bandwidth luminance signal in response to the motion signal.  This regenerated full bandwidth luminance signal is combined with the chrominance signal to reproduce the originally recorded composite video signal.  A recording medium previously recorded by such a recording system is capable of being  played  back  on  a  standard  playback  system  without objectionably artifacts in the reproduced image.
