Title: Picture encoding method, picture encoding apparatus and picture recording medium
Inventor: ODA TSUYOSHI
IPC: H04N19/174
Filed: 1994-04-11
Granted: 2003-07-22
Abstract: A mechanism for encoding an input video signal, e.g. predictive encoding, or DCT processing, based on a fixed quantization step size and variable length encoding. A first bit stream is generated and an encoding rate corresponding to a predetermined period is determined based on (1) the quantity of available data associated with the first bit stream, (2) the encoding difficulty, and (3) the quantity of usable data. Further on, the input video signal is quantized based on the encoding rate previously determined, and then variable length encoding is performed to generate a second bit stream. Thus, a variable rate is obtained as the encoding rate changes every predetermined period. In the case when the second bit stream is recorded onto picture recording media, the memory capacity is efficiently used and the recording time is extended. Even when pictures of a complicated pattern are successive, the quantization step size does not become too large and therefore, uniform high quality picture is obtained throughout the entire transmission.

Abstract: Dispositif servant à éviter les interférences et utilisé en combinaison avec un système de détection d'une cible de véhicule. La section émetteur-récepteur à micro-ondes (102) du système de détection de cible, dans laquelle l'invention est incorporée, émet et reçoit des signaux micro-ondes multiplexés dans le temps (104) possédant au moins deux canaux (fréquences) espacés d'environ 250 kHz. Le signal d'émission multiplexé dans le temps est émis et heurte des objets (cibles) situés dans l'environnement et une partie du signal d'émission est réfléchie vers l'antenne. Un signal de différence, dont la fréquence est égale à la différence entre la fréquence du signal d'émission et celle du signal de réception, est généré, numérisé et une transformation rapide de Fourier (FFT) s'effectue sur le signal de référence numérisé. Un microcontrôleur (106) analyse le spectre d'énergie, de façon à déterminer la présence d'une interférence. Dans ce cas, le microcontrôleur provoque la modification de la fréquence d'émission, jusqu'à la découverte d'une fréquence relativement exempte de l'interférence.

Abstract: A speed indicator for marine vehicles is mounted on the lower transom area of such a vehicle and includes an impeller. The impeller rotates at an angular velocity dependant on the speed of marine vehicle relative to the water. A mounting bracket secures the speed indicator to the marine vehicle in a manner to permit movement of speed indicator relative to the marine vehicle so that the axis of the impeller remains generally in line with the direction of travel of the marine vehicle. To try to ensure laminar flow across the impeller and to facilitate movement of the speed indicator, the speed indicator has a guide vane positioned upstream of the impeller. The mounting bracket also permits adjustment of the speed indicator so that the axis of the impeller is basically parallel to the plane of the bottom of the marine vehicle.        A sensor including a magnetic conductor and a magnetic pick-up detects rotation of the impeller and generates output representative of the speed of the marine vehicle. In one embodiment, the magnetic pick-up is supported by the speed indicator above the water level.

Abstract: Fluid flow in a conduit is measured by placing a flow block in the conduit which introduces variations in the flowpath which cause local  pressure variations.  The pressure variations are converted to electrical signals by transducers,  and the electrical signals are  processed to obtain flow rate values.  To provide a correction for transducer drift,  the transducer  signals are examined during a time when there is known to be zero flow in the conduit. The difference between the transducer signals during a time when there is zero flow is used as a measure of  transducer drift.  A value for the drift is stored in computer memory and used subsequently, when fluid flow is resumed.  This invention is specifically intended for use in railroad  airbrake  systems, where it is used in a locomotive to provide an accurate and reliable measurement of air supplied to the brake pipe of the air brake system.
