Abstract:
A controlling device for operating a PC and one or more home appliances. The described controlling device has integrated mouse and remote control functions, and may be configured to automatically detect whether the controlling device is being used as a mouse or as a remote control. For effective operation in both control modes, the controlling device includes both RF and IR transmitters, and is configured to transition between these transmission mediums based on the detection of whether the controlling device is being used as a mouse or as a remote control.
Abstract:
A controller for a device transmitting commands across one or more communication channels. Each such channel may employ a separate medium, such as radio waves and infrared light. The controller may transmit two separate signals to a device, where one signal is sent via radio waves and the other by infrared light. One signal may correspond to a group identifier and the other to an operating command to be carried out by the device. The device may receive both signals and, if the device belongs to a group corresponding to the group identifier, it may execute the operating command. Alternatively, the group identifier may be replaced by a wake command and the device may execute the operating command only if the wake command is received.
Abstract:
The invention discloses a system for controlling household digital equipment based on wireless. The system comprises a remote device and receiving devices. The remote device sends controlling commands in wireless mode and provides at least two kinds of wireless communication modes. The receiving devices can communicate in the said wireless communication mode, can receive the controlling commands, which are sent by the remote device and can make the household digital equipment perform the controlling commands. The remote device selects the corresponding wireless communication mode according to the controlling commands and communicates with the receiving devices by the selected wireless communication mode.
Abstract:
In order to control automatic working devices, especially soil compacting devices, a remote control device is provided which comprises a transmitter unit (2) which can be actuated by a user and which is used to transmit control signals in the form of electromagnetic radiation and a receiver unit (3) which is arranged on the working device (1) and which outputs the received control signals in the form of electric control commands to the control unit of a working device (1). During operation of the working device, the transmitter unit can be connected to an external power source (4), which is arranged on the working device, by means of a cable (5) for the supply of power thereto.
Abstract:
Système de commande à distance comprenant au moins un dispositif d'émission (A) ayant une entrée de commande (C) et agencé pour émettre au moins un signal de commande (1) produit sur base d'informations introduites par un utilisateur dans ladite entrée de commande, et un dispositif de réception (B) agencé pour recevoir ledit au moins un signal de commande (1) et le transmettre à une machine (D), le système de commande à distance comprend un générateur d'instruction (E), agencé pour produire sous contrôle du signal de gestion au moins un signal d'instruction (3) comprenant une action à exécuter, et étant agencé pour diffuser ledit au moins un signal d'instruction, ledit générateur d'instruction étant relié à un vérificateur (F) agencé pour comparer le signal d'instruction avec l'autre signal d'instruction.
Abstract:
The invention relates to a conducting system for a building or for one or several rooms in a building, comprising a central unit and at least two components linked to the central unit by radio. The central unit receives signals from the components or transmits signals to the components. The signals are transmitted within a predetermined frequency range. To improve the reliability of signal transmission each signal is transmitted on at least two different frequencies within the frequency range. In addition, at least one of these frequencies is located outside a partial frequency range of the frequency range, which is usually used by other devices communicating by radio. Redundant signal transmission on the one hand and targeted frequency selection on the other hand improve the reliability of signal transmission.
Abstract:
An apparatus and a method for providing remote control capability involves transmitting IR and RF signals in a time multiplexed manner. The present apparatus comprises an input device (20), and IR signal transmitter (16), a RF signal transmitter (17) and a controller (14) operatively coupled to the input device, the IR signal transmitter and the RF signal transmitter. The controller generates and applies the IR and RF signals to the respective signal transmitters in time multiplexed manner. The IR and RF signals may be transmitted using different protocols without significantly increasing the computing capacity of the controller as compared to a controller of a remote control device which transmits only one type of remote control signal.
Abstract:
Für eine Fernbedienungseinrichtung, insbesondere mit Positionssteuerung, wird eine Spreizcode-Übertragungsstrecke (R) angegeben, auf der mindestens drei unabhängige Spreizcode-Signale S1', S6', S18' übertragen werden. Auf der Empfängerseite werden diese Signale mittels dreier Korrelatoren (K2, K4, K5) wieder in ihre einzelnen Komponenten getrennt und bilden die Diodensignale (d1, d2, d3). Synchronisationseinrichtungen auf der Empfängerseite mit weiteren Korrelatoren (K1, K3) bewirken, daß mittels einer Phasenregelschleife und einer Steuereinheit (st) Synchronismus zwischen den empfangenen Spreizcode-Signalen (S1', S6', S18') und den zugehörigen Referenzsignalen (S1, S6, S18) hergestellt wird.
Abstract:
Ein redundant betreibbares Kommunikationssystem für ein industrielles Automatisierungssystem umfasst zumindest ein erstes und zweites Kommunikationsgerät sowie zumindest 4 Netzinfrastrukturgeräte. Das erste Kommunikationsgerät ist redundant mit einem dritten Kommunikationsnetzanschluss eines ersten und zweiten Netzinfrastrukturgeräts verbunden. Das zweite Kommunikationsgerät ist redundant mit einem dritten Kommunikationsnetzanschluss eines dritten und vierten Netzinfrastrukturgeräts verbunden. Das erste und dritte Netzinfrastrukturgerät sowie das zweite und vierte Netzinfrastrukturgerät sind jeweils über ihren ersten und zweiten Kommunikationsnetzanschluss miteinander verbunden. Während das erste und zweite Kommunikationsgerät redundant zu sendende Datenrahmen durch einen ersten Indikator kennzeichnen, kennzeichnen das erste und dritte Netzinfrastrukturgerät sowie das zweite und vierte Netzinfrastrukturgerät redundant zu sendende Datenrahmen durch einen zweiten bzw. dritten Indikator, der sich vom ersten Indikator unterscheidet, und verwerfen am dritten Kommunikationsanschluss empfangene durch den zweiten bzw. dritten Indikator gekennzeichnete Datenrahmen.
