Abstract:
The invention relates to an arrangement comprising an actuator (500), at least one transmission device (100) for transmitting control telegrams (T(K1), T(K2)), which each contain a pre-defined control command (SB) for the actuator or constitute the pre-defined control command in themselves, at least two receiving devices (200, 300) for receiving the control telegrams and generating a control signal (ST1, ST2) for the actuator, and a decider device (400), which connects the receiving devices to the actuator and which only allows the actuator to implement the control signals of the receiving devices by means of a release signal if the control signal is present from all the receiving devices or from at least a pre-defined minimum number of receiving devices, the transmission device being designed so as to transmit the pre-defined control command to each respective receiving device with a receiver-specific control telegram, each receiver-specific control telegram being provided with a respective control instruction that indicates the continuous telegram number of the respective transmitted control telegram in encrypted or non-encrypted form, and each of the at least two receiving devices being designed so as to accept a received control telegram as valid on the basis of the control instruction if the control instruction indicates a telegram number that corresponds to the continuous telegram number expected by the receiver, and generates the control signal for the actuator for a respective pre-defined time period if a valid control telegram is received.
Abstract:
A passenger services system (100; 200; 300; 400; 500; 832) of an aircraft 8802) includes a cabin services system of a passenger service unit in the aircraft. The passenger service unit is associated with a passenger seat of the aircraft. The passenger services system further includes an infrared transmitting unit (120; 220; 320, 340, 370, 380; 424, 434, 444) associated with the passenger seat. The infrared transmitting unit is configured to send signals to control operation of the cabin services system. The passenger services system includes a control unit (160; 260; 460) including an infrared receiver. The control unit (160; 260; 460) is associated with the passenger service unit. The infrared receiver is configured to receive the signals from the infrared transmitting unit. The control unit (160; 260; 460) is configured to control the operation of the cabin services system in response to receiving the signals.
Abstract:
A method and a device for determining what commands can be used to operate a receiving device (110) when a user operates a control device (105). After such a determination is made, a first command is transmitted to the receiving device from the control device (105) over a first communication interface and a second command is transmitted to the receiving device (110) over 5 a second communication interface. The communication interface that is selected depends on whether the control device can control the operation of the receiving device (110) with such a command directly or whether an intervening device (130/140) is required to translate the command from a first format to a second format.
Abstract:
Bei dem Verfahren und der Vorrichtung zur drahtlosen Übertragung von Signalen zwischen einem mobilen Bedienteil (2) und einem Basisteil (4) eines insbesondere medizinischen Behandlungsgeräts werden die zu übertragenden Signale kategorisiert, nämlich in sicherheitsrelevante Steuersignale (S) und unkritische Kommunikationssignale (K). Lediglich die sicherheitsrelevanten Steuersignale (S) werden insbesondere als codierte Signale übertragen und auf Übertragungsfehlersicherheit überprüft. Die unkritischen Kommunikationssignale (K) werden demgegenüber ohne Sicherheitsüberprüfung übertragen. Durch diese Maßnahme ist eine einfachere programmtechnische Einrichtung und damit auch Überprüfung und Wartung ermöglicht.
Abstract:
A remote data concentrator receives signals from a plurality of sensors (22,24,26,28). Each of the sensors have their signals split between at least two flow paths (31,33), such that each of the sensors are provided with redundancy.
Abstract:
The invention relates to a device having a modular design, comprising a control unit (1) having at least one sensor (2) or actuator connected to the control unit (1), designed for transmitting data between the control unit (1) and the sensor (2) or the actuator, wherein according to the invention, the control unit (1) is connected to the sensor (2) or the actuator by two separate wireless transmission lines (3, 4), wherein the transmission of data between the control unit (1) and the sensor (2) or the actuator is carried out via the two transmission lines (3, 4) using different transmission parameters/techniques.
Abstract:
System for the remote control of at least one electrical household appliance that comprises a first transmitter/receiver (10b) and an auxiliary receiver (10a) incorporated into the electrical household appliance, and a second transmitter/receiver (11b) and an auxiliary transmitter (11a) incorporated into a remote control device (2) that includes a screen (3) for displaying information received by and/or transmitted from said remote control device (2). The system of remote control uses a primary system (A) of short-range communication between the auxiliary transmitter (11a) and the auxiliary receiver (10a) and a secondary system (B) of long-range communication between the first transmitter/receiver (10b) and the second transmitter/receiver (11b), enabling a critical-parameter control command (17) to be sent from the remote control device (2) to the electrical household appliance via the secondary system (B) only once said secondary system (A) is activated, said secondary system (B) then being bidirectional.
Abstract:
A transmitter for transmitting an RF control signal to a remote system includes a user input device, a memory and a transmitter circuit. The memory includes control data associated with the remote device. The control data includes a first frequency and a second frequency. The transmitter circuit is coupled to the user input device and memory. In response to a single user input, the transmitter circuit generates a rolling code signal, transmits the rolling code signal at the first frequency for a predetermined amount of time, and, upon expiration of the predetermined about of time, transmits the rolling code signal at the second frequency.
