Abstract: L'invention concerne un procédé permettant d'indiquer une erreur dans les paquets (62) dans un système de communication (10) à plusieurs bonds, dans lequel les paquets (17) de données sont transmis d'un site de transmission (14) vers un site de réception (32), par l'intermédiaire d'une pluralité de liaisons physiques successives (22a, 26a, 28a, 30a, 22b, 26b, 28b, 30b, 22c, 26c, 28c, 30c). Au site de transmission, le bit (62) défini au préalable dans un paquet (16) à transmettre est mis à une première valeur indiquant l'absence d'erreur dans le paquet. Ensuite, à chaque liaison physique successive, après transmission du paquet par cette liaison, on effectue les opérations suivantes: détection (82) d'éventuelles erreurs non corrigibles produites durant la transmission du paquet sur cette liaison; lorsqu'on détecte une erreur non corrigible, mise (90) du bit défini au préalable dans le paquet à une seconde valeur indiquant une erreur non corrigible dans les données du paquet; et acheminement (88) du paquet vers la liaison physique successive suivante, pour une transmission sur cette liaison suivante. Un décodeur (32) au site de réception peut, à la réception d'un paquet donné, examiner la valeur du bit défini au préalable pour déterminer si les données, contenues dans ce paquet, ont conservé leur intégrité.

Abstract: The present invention involves a control system for a motor having a main winding and an auxiliary winding disposed on a stator. A microprocessor determines the phase difference between the line voltage and the voltage between the main winding and the auxiliary winding to determine the rotational status of the rotor. In a moving rotor, a measurable phase difference exists. This phase difference can be measured by monitoring the zero crossings of the respective voltages. One method of measuring the phase difference is to check the logic state corresponding to the voltage between the main and auxiliary windings when a predetermined time period has elapsed after a zero crossing of the line voltage. Another method measures the time delay between the zero crossings of the two voltages. The control system of the present invention is particularly adapted for use with single phase AC motors having a main winding and an auxiliary winding disposed electrically out of phase on the stator. The control system of the present invention is also particularly adapted for use with compressors and appliances associated with a refrigeration system having a cabinet temperature detector. The refrigeration system of the present invention includes a motor housing detector to deenergize and prevent motor start if an overheat condition exits, and a user setting device to allow a user to manually add an offset to the temperature setting. Additional control functions can be easily added using extra input and output leads provided on the microprocessor.
