摘要:
An air conditioning control system with a hermetic compressor for a motor vehicle is disclosed. The control system comprises a system for controlling the speed of the hermetic compressor (34) in such a way that the compressor driven by a variable-displacement pump assembly (30) coupled to a fixed-displacement hydraulic motor (33) rotates at a speed that is as close as possible to the rated compressor speed, and a sensor device (8) enables measurement of the rotation speed of the shaft of the hydraulic motor (33) connected to the compressor (34), so that a comparator (1) can change the forward direction of the plate (31) of the variable-displacement pump (30) depending on the changes in the speed of the hydraulic motor relative to a set speed.

Audiovisual distribution system in which each of the audiovisual units (8) includes means for interactively communicating with the user for selecting a piece or a menu, payment means, a computer network card, a permanent semiconductor memory containing a multitask operating system comprising at least a hard disc access management task. The order for performing a selected piece is processed as a hard disc sequential access task. The hard disc is declared as a peripheral corresponding to the network card of the unit, enabling a request to be sent through the network to a server (9) for processing thereof.
摘要:
Payment-based audiovisual playback system comprising a microprocessor device associated with a payment device primarily including mass storage means, for storing inter alia the digital compressed visual and sound information to be used. The system is associated through interfaces with digital display means and digital sound playback means which provide a multimedia environment. The invention is characterized in that the digital display means and video monitor are associated with a touch screen associated with an interface programme responsive to outside events, translating them, for the graphic operating system, as mouse events using a library of integrated tools and services, to trigger either a change in the execution of one of the man/machine interface programme modules, or a change in the physical operating parameters of the jukebox.

摘要:
Le procédé de sélection d'un enregistrement sur un système de reproduction audiovisuel est caractérisé en ce qu'il consiste à afficher une pluralité de fenêtres dans un écran, à envoyer, par sélection des données nécessaires à la visualisation, à chacune des fenêtres les informations mémorisées dans la mémoire de masse et représentatives d'une image de la pochette associée à chaque fenêtre et dont l'enregistrement musical correspondant est mémorisé dans la mémoire de masse du système de reproduction et en ce qu'à chaque zone d'une fenêtre sont associées par le logiciel d'interface de l'écran tactile, au moins une adresse d'accès aux informations de la base de données stockée sur la mémoire de masse concernant la pochette de l'album dont l'image est représentée dans la fenêtre touchée par l'utilisateur.
摘要:
Digital home audiovisual information recording and playback apparatus comprising a microprocessor associated, through a digital interface, with display means, through another interface with sound playback means and through a telecommunications interface with means for loadind audio selection or visual selection digital information. The invention is characterized by control means (1021 to 1025) for controlling display means, enabling an operating mode to be selected from a menu of three modes, in which the device either plays back information stored in its mass memory, records new digitalized information in its mass memory or combines analog information from a microphone with digitalized information received from the mass memory.
摘要:
Payment-based audiovisual playback system characterized by comprising a microprocessor unit, primarily including storage means for storing inter alia in digital form the visual and sound information to be used, and associated, through a number of interfaces, with display means for sound playback which provide a multimedia environment. The unit is controlled by a multitask operating system including a library of integrated tools and services in the storage means. The system is also associated, through an interface, with a telecommunications modem and is connectable to an audiovisual information distribution network by a telecommunications modem and telecommunications links, the telecommunications functions also being managed by the multitask operating system.
摘要:
Method of communication for an intelligent digital, audiovisual playback system. The method for communication between a central server and a computerized jukebox is characterized in that it operates in a conference mode and includes sending, prior to any transaction, a header including the identity of the destination target, the originator identity and the packet size; sending the response of the server as a data packet, each packet from the server being encrypted by the code which identifies the jukebox software. The jukebox receives and then decrypts the data packet. At the same time the packet controls the data received by the cyclic redundancy check method (CRC) and sends an acknowledgement of receipt to the server stating that the information received is accurate. The server can then prepare a new packet addressed to the unit.
摘要:
System for distributing and selecting audio and video information using a coaxial cable network. The system comprises a jukebox unit (1) connected by a modulator (9) to the cable television distribution network characterized in that it includes a channel allocated to the transmission of audio or video information; associated means (T1, 83) for interacting with the television for the remote selection of at least one audio or video information item from the plurality of information items to be transmitted by this channel using the cable network; means for identifying the selection means or the television associated with the selection means; and means associated with a television set for billing selections to the user.
