摘要： A method and apparatus for controlling access to television programming uses a remote control device. The remote control device contains program control data which limits the viewer's access to television programming. The program control data is created and modified by a user with the master control user id assigned to the remote control device. The remote control device is optionally assigned one or more user ids for creating, maintaining, and in one embodiment activating a user-customizable profile which controls programming access according to the users' preferences. The program control data, user profile data, and related circuitry is stored in the remote control device, or alternatively in the television receiver or a control device attached to the television receiver. Where the circuitry is not in the remote control devices the remote control device has a unique identifying signal which causes the programming control circuitry to employ the program control data and user profile data associated with that particular remote control device.

摘要： A position sensor comprises two curved surfaces concentrically aligned to form a container which is filled with a viscous fluid and a bubble of a lighter-weight fluid and placed between a radiation source and a radiation detector. The bubble changes position within the container when the sensor is moved, transmitting a beam of radiation from the radiation source through the bubble to activate a section of the radiation detector while the remainder of the radiation is blocked by the fluid. Position sensing circuitry translates a signal from the activated section of the radiation detector into position coordinates for point in space corresponding to the position of the bubble in the container. The position sensor is suitable for use in a digital controller that generates display attributes to define a locator symbol on an output device. The digital controller can include an optional button to permit a user to change the size of the locator symbol, making it appear to approach or recede, to provide a simulated three-dimensional display.
