摘要:
A remote control apparatus is constituted by a command encoding device and a command decoding device. In the command encoding device, a timing pulse generator indicates the beginning and end of a time interval of a length which is a function of a command to be encoded, a pulse of the first duration shorter than said time interval is initiated in response to said beginning of the time interval, a pulse of a second duration different from said first duration and shorter than said time interval is initiated in response to said end of the time interval, and said pulses of said first and second duration respectively, are sequentially transmitted in the command decoding device, upon the receipt of a pulse of said first duration followed by a pulse of said second duration, a first indication is produced in response to the receipt of said pulse of the first duration and a second indication is produced in response to the receipt of said pulse of the second duration, and a device provides a value which varies as a function of the length of time between each said second indication which immediately precedes it, whereupon, a command signal is produced as a function of said value.

A remote control system for TV receiver control. The system uses infra-red transmission to trasmit an infra-red data pulse on each edge of a pulse duration signal comprising a coded pattern of binary 0 and 1 bits which are formed by pulses of respective different lengths. The original pulse duration signal can be reconstituted at a receiver by a bistable element which is responsive to the infra-red data pulses. Since the regenerated modulating waveform could be in anti-phase with the original modulating waveform, the sequence of data pulses is transmitted twice and an additional data pulse is transmitted between successive transmissions, so that one or the other of the two regenerated modulating waveforms must be in phase with the original modulating waveform.

A remote commander in which a switching element connected in series to an infrared light-emitting diode is turned on and off in response to carrier pulses to energize the infrared light-emitting diode to generate an infrared remote control signal includes varying means for varying duty ratios of carrier pulses.

A remote coordinate designating device has a remote control with a light emitting device for emitting light, and a controller for detecting a designated position by receiving light from the remote control at a distance from the remote control. One cycle of a light signal from the light emitting device is composed of switch data and a coordinate detection timing header at the head, and a coordinate detection carrier. The switch data and the coordinate detection timing header use the same frequency as the normal remote control frequency band, and the frequency of the coordinate detection carrier is lower than the frequency of the switch data and the coordinate detection timing header. The switch data contains on-off information about a switch for pointing, and coordinate detection is started when a predetermined time has passed from the rise of a burst portion in the switch data.

A remote-control unit for a video receiver is provided, inter alia, with a numerical keyboard (23) for transmitting code numbers between 0 and 9, and, as the video receiver is provided with a credit card reader for allowing payments, the remote-control unit comprises enciphering means for transmitting, during activation of a key from 0 to 9, a code representing a numerical value J which is different from the value I corresponding to the activated key, such that for I between 0 and 9, J is also between 0 and 9.

An input apparatus for controlling a display device by using the screen display of the display device includes cursor moving unit for moving the position of a cursor on the screen of the display device, switching unit which is provided in conjunction with the cursor moving unit, and a controller for controlling at least the on/off operations of the input apparatus upon the display device. The switching unit switches on the power supply to the controller in accordance with a movement of the cursor moving unit.
摘要:
A remote control system includes a first remote control unit having complete functional capabilities and a second remote control unit having simplified and abbreviated functional capabilities. An apparatus is controlled in a detailed manner by the first remote control unit. For example, the operational mode and timer settings are set by the first remote control unit. On the other hand, the second remote control unit is limited to activating and deactivating the apparatus and/or the timer of the apparatus.
摘要:
Apparatus and method for switching between two input sources to a television receiver and/or video recording device. Switching may be carried out with a conventional remote control otherwise dedicated to the video recorder or television receiver by holding down a control button thereof for at least a predetermined interval of time, for example two seconds. Five RF diode switches along with solid state logic components are employed to respond to the remotely developed switching signals for carrying out TV receiver and VCR source selections by the viewer. The pre-existing television or VCR operational status is not affected by the remote controllers where an ongoing channel selection simply is reinforced or a function of the remote controller is elected which has no undesired effect upon that ongoing operational status.

An input device including a case defining an opening, a bearing member pivotally mounted in the case about an axis and disposed adjacent to the opening, a roller rotatably disposed on the bearing member and having a portion exposed through the opening, an encoder disposed adjacent the axis of the bearing member and coupled to the roller by a belt, and a push button switch disposed to contact a portion of the bearing member away from the axis, such that manual rotation of the roller causes the belt to rotate the encoder, thereby producing a first output signal, and pressing the roller causes activation of the push button switch by pivoting the bearing member, thereby producing a second signal. A water receiving member is disposed in the case between the bearing member and roller. The water receiving member has a main chamber into which is disposed the roller, and a subchamber connected to the main chamber by a cut-out passage. A drainage passage is formed in the case and connected to the subchamber for allowing water to exit the main chamber.
摘要:
A remote controller capable of learning and later transmitting infrared signals transmitted by any other remote controller. The remote controller determines which of four modes of transmission a signal is transmitted in, including carrier mode, pulse mode, frequency shift keying mode and continuous wave mode. Once the type of signal is determined the controller learns each signal, saves them and later replays them to control a remote device.
