摘要:
A computer-implemented method for controlling an electronic device including receiving a signal through a light sensor of the device, identifying with a processor of the device whether the received signal originated from a light emitter of the device, and controlling a function of the device, the function selected based on whether the signal is identified as originating from the light emitter of the device or the light emitter separate from the device.

An easy to use on-line guide provides the user of a multiple channel television broadcast system with a wealth of programming information in a simple format that is easy to understand. The guide enables the user to easily select a particular program to watch. In particular, when the guide is presented to the user, the guide covers only a portion of the actual television screen or display. The remaining portion of the television screen continues to broadcast the audio and video of the currently selected program. As a user scans through the guide and moves the pointer from one station to another, the system responds by automatically tuning to the channel pointed to by the pointer and provides the audio and displays the video in the portion of the screen not covered by the guide. Furthermore, a written description of the program currently broadcasted on a station that the cursor currently points to is also shown. In addition, the system provides an innovative mechanism to enable the user to scan program information of channels that the user has designated as his favorite channels. In another embodiment, a program list that is oriented according to the program, instead of the channel, is presented.
摘要:
An electronic system including a connector (J1) for an external device such as an infrared receiver (12) includes a signal processor (20), responsive to the infrared receiver and an electrical isolation device such as an optocoupler (18), coupled between the connector (J1) and the signal processor (20). Such a system can further include electromagnetic interference suppression circuitry such as a ferrite bead (14), capacitors (C1, C2) coupled to the earth potential, coupled between the connector (J1) and the optocoupler (18). Such a system can also further include electrostatic discharge suppression circuitry resistors (R1, R2) coupled between the connector (J1) and the optocoupler (18). Application: infrared remote control devices.
摘要:
A programmable remote controller is programmed by a PC that has an onboard data base for sets of codes used by a variety of commercially available remote controllers. The data base contains sets of compressed codes. In order to program the remote, the user lets the PC find a match between a single pulse-code transmitted by a specific known controller on the one hand and an item in the data base on the other hand. Upon finding the match, the set containing the matching item is stored in the programmable controller as corresponding to the particular apparatus that is controllable via the specific remote.
摘要:
A remote control system having a television receiver (45) which can be controlled by infrared remote control signals. The remote control system comprises: remote transmitter means for transmitting remote control signals including a user-rotatable roller (2a) supported by a flexible axis (11), rotation detecting means (1) provided to detect the rotating direction and the amount of rotation of the roller, first detection circuit (3) for generating first control signals signifying the rotating direction and the amount of rotation in dependence on the signals from the rotation detecting means (1), a switch (2) for being responsive to the pushing activation of the roller (2a), second detecting means (4) for generating second control signals in response to the switch activation, and means (5,6) for encoding and transmitting remote command signals to the television receiver in accordance with the first or second control signals.
