Abstract:
System for the remote control of at least one electrical household appliance with a first transmitter/receiver and an auxiliary receiver incorporated into the electrical household appliance, and a second transmitter/receiver and an auxiliary transmitter incorporated into a remote control device that includes a screen for displaying information received by and/or transmitted from the remote control device. The system of remote control may use a primary system of short-range communication between the auxiliary transmitter and the auxiliary receiver and a secondary system of long-range communication between the first transmitter/receiver and the second transmitter/receiver, enabling a critical-parameter control command to be sent from the remote control device to the electrical household appliance via the secondary system only once the secondary system is activated, the secondary system then being bidirectional.
Abstract:
A smart portable device transmits a keyless radio signal for a keyless entry system by two frequency channels. In an integrated tuner, a control IC determines a frequency channel having a better communication state, and controls a frequency of a signal that is input to a mixer from a PLL circuit to a frequency for converting the keyless radio signal of the determined frequency channel into an intermediate frequency signal. This configuration makes it possible to share a circuit for receiving the keyless radio signals of those two frequency channels, and to receive the keyless radio signal of the frequency channel having the better communication state to surely conduct communication.
Abstract:
A device includes a sensor which generates a value representative of a position of the device relative to an object surface. The device then uses the value obtained from the sensor to automatically transition from a first state in which the input interface is enabled to a second state in which at least a portion of the input interface is inhibited.
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:
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:
An AM/FM modulation scheme is presented for optimizing communications between a remote control device held by a user and a receiving unit installed in a vehicle. Historically, these systems communicated with amplitude modulated signals having good range but poor immunity to ambient random radio frequency noise. Frequency modulated systems provide improved immunity to noise however at the expense of range. The object of this invention is to use two or more modulation modes to combine their advantages. A scheme has been devised whereby circuitry capable of alternately operating in at least two modes is used. The same information is therefore transmitted using two or more modulation techniques in succession. The receiving unit also has circuitry and has listening cycles ensuring eventual synchronization with the transmitting unit. If one mode fails due to distance or ambient noise, the other can then attempt to establish a link.
Abstract:
In order to control automatic working devices, especially soil compacting devices, a remote control device is provided which comprises a transmitter unit 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 which is arranged on the working device and which outputs the received control signals in the form of electric control commands to the control unit of a working device. During operation of the working device, the transmitter unit can be connected to an external power source, which is arranged on the working device, via a cable for the supply of power thereto.
Abstract:
A remote control, particularly for wireless remote control of a closing device in a motor vehicle, has a first transmitter for outputting an optical signal, and a second transmitter for outputting a radio signal. The two transmitters are able to be activated for signal output by at least one actuation element. An input of the first transmitter and/or of the second transmitter is connected to a clock transmitter in order to output the optical signal and/or the radio signal in pulsed fashion at particular intervals of time in order to save energy. Also an associated remotely controllable device and a full remote control configuration are disclosed.

Abstract:
An optical signal transmission device includes an emitter, a receiver, and a reflector. The emitter includes a light-emitting element having an optical axis thereof deviating from a first propagation path toward a second propagation path such that a ratio of an incident intensity, at the receiver, of a second optical signal propagating along the second propagation path to an incident intensity, at the receiver, of a first optical signal propagating along the first propagation path is equal to or higher than a predetermined value at or above which a faulty optical-signal transmission is not caused, whereby the second optical signal of a required level enters into the receiver for reliable and stable optical signal transmission.
