Abstract:
Die Erfindung betrifft ein Verfahren zur Datenübertragung zwischen einem mobilen Funksender und einem Funkempfänger einer Maschine oder Anlage, wobei eine erste Funkverbindung zwischen Bediengerät und Maschine/Anlage zur Übertragung von sicherheitsrelevanten Informationen und eine zweite Funkverbindung zur Übertragung von nicht-sicherheits-relevanten Informationen vorgesehen ist.
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:
A communications system for transmitting and receiving remote control messages in an electronic remote control system. The present communications system uses a remote control message protocol which is particularly suitable for transmitting RF remote control messages with IR remote control messages in a time multiplexed fashion, wherein the RF remote control messages are transmitted during the pause intervals between IR remote control message transmission intervals. The present remote control message protocol (80) includes a start sequence (82), comprising a MARK pulse and a SPACE of about equal duration, followed by a plurality of data fields. Each data field ends with an End of Field marker (85) and the remote control message ends with an End of Message marker (87). The plurality of data fields comprises an addressing data field (89) for specifying the destination device, a security code data field (89) for allowing a specific remote control transmitter to control a specific destination device, a status field (88) for specifying various status codes associated with the remote control message, a keycode field (90) for carrying the remote control message payload, and a checksum field (92) for verifying the transmission integrity of the remote control message. A remote control message based on the present message protocol may be expanded to include additional data fields and to expand pre-existing data fields.
Abstract:
The invention realises a remote controlling device (1) of an operative machine which comprises a transmitter (2) arranged on the ground at the disposal of an operator and a receiver (3) arranged inboard, supplied with an accomplishment circuit (24) connected with the drives (25) of such machine. The transmitter (2) comprises a first section (2') which transmits luminous infrared waves (6) and a second section (2'') which transmits electromagnetic waves (17) which cooperate with the receiver (3) comprising a first section (3') receiving the luminous infrared waves (6) and a second section (3'') receiving the electromagnetic waves (17). In the receiver (3) electronic means (19) are present, suitable for realising a permission signal (20) which activates the accomplishment circuit (24) only if the first receiving section (3') receives the luminous infrared waves (6) emitted by the first transmitting section (2').
Abstract:
A remote receiver accepts command signals from infrared transmitters and radio frequency transmitters and combines the command signals into a final non-overlapping command signal according to a preselected priority among the command signals. In an alternative arrangement a video system (10) includes a receiver (12) that generates a remote identifier setup display on a television monitor (14) and a remote control unit (16) having a radio frequency transmitter and an infrared transmitter. The video system enables a user to enter a remote control identifier for the radio frequency transmitter through the remote identifier setup display using the infrared transmitter. The receiver initially ignores remote command signals received from the radio frequency transmitter until the remote control identifier is entered.

Abstract:
PURPOSE: A circuit for suppling a power for an electric device is provided to reduce power consumption and to make the power consumed in an electric device zero at a stand-by state. CONSTITUTION: A circuit for suppling a power for an electric device includes a main power suppling circuit(2), a receiving unit(10), a controller(24), a first power supply(21), a second power supply(22,41), a first switching unit(23,43) and a second switching unit(3). The main power suppling circuit supplies a power for a first load circuit necessary for a normal operation at a normal operation based on an AC power supply(1). The receiving unit receives a remote control signal from a remote controller. The controller receives the remote control signal from the receiving unit, and controls the device body in response to the remote control signal. The first power supply receives an electromagnetic wave from the remote controller, and generate a DC(Direct Current) voltage by converting the received electromagnetic wave into an electric energy. The second power supply is a stand-by power supply for suppling a power for a second load circuit( including at least the controller and the receiving unit). The first switching unit is connected between the second power supply and the second load circuit, and turns on or off the connection of the second power supply with the second load circuit in response to the DC voltage from the first power supply. The second switching unit turns on or off power suppling from the AC power supply for the main power supply circuit, and switches in response to the remote control signal received from the receiving unit.
