Abstract: A remote controlled system employs a computer-based remote control facilitator to facilitate remote control of a controlled device from a non-dedicated remote controller. The computer facilitator is coupled to the remote controller and controlled device via a wireless or wire-based network. In one implementation, the computer facilitator is a general-purpose computer that runs an open platform operating system. The computer facilitator runs an application that corresponds to the controlled device. The application contains program code, data, information, and any other intelligence that may be used by the facilitator to assist the remote controller in controlling the controlled device. Neither the remote controller nor the controlled device need have any awareness of the other, or any knowledge as to how to communicate with one another. The remote controller gains its power and flexibility from the general-purpose computer.

When an operation to select and demand the FM mode on the rear side in a dual mode while the front side is in the AM mode, the control unit inhibits the FM mode selection on the rear side so that the AM mode on the front side may not be changed into the FM mode.

Abstract: In a mobile communication system, when a connection necessary to provide a service supporting high-speed data communication referred to as an MBMS is configured on an Iu interface, contention with the other packet communication service is eliminated. As a logical connection established between an SGSN and a Radio Network Controller in a Core Network 10, a PS (packet switching processing) functional connection for an existing packet communication service and a connection for a new MBMS service offering high-speed data communication are provided separately and independently from each other. This eliminates the contention between different types of services of the PS service and the MBMS service to thereby enable executing processings of such different types of services without being conscious of mutual processings. In addition, release processing of the connection may be executed independently to each service, thereby eliminating processing complexity in the SGSN.

For each node pair in this order, then a path P is selected for implementation among all possible paths, which path P satisfies the condition that (I) is minimum.

Abstract: The invention is a radio inside a vehicle providing each of the multiple drivers to automatically pre-set her radio adjustment settings for subsequent use. In the case of a “family car” where parents and young adults in the family share a car, the radio adjustment preferences (e.g., volume, bass, treble, etc.) for each driver are likely to be different. The more drivers there are to this “family car”, the more difficult it becomes for each driver to enjoy the comfort this radio affords because of the speaker adjustments required every time one turns on the radio.

Abstract: A network protocol allows small wireless devices to be used for the control of remote systems. Several features promote fast and efficient modification of system parameters despite the small form factor of most wireless devices. First, each card is preferably designed such that the status of a control variable, and a control to permit the variable to be changed, are located on the same card. Second, the menu is structured such that rather than forcing the user through a series of data entry cards for every possible parameter, the user may select only the parameter which requires changing. Third, the interface is structured such that, each time a control variable is set, the user is taken back automatically to the previous card up one level in the menu structure. Fourth, the interface is structured to go back a level when the user opts out of a change.

Abstract: A handheld remote controller for a televisor that automatically prefixes a single-digit program channel selection, typically between 2 and 9, with a leading zero in response to a prolonged single digit keybutton actuation exceeding about 3 seconds or by an intended ersatz key entry, such as a star “*” key, either preceding or following the channel digit key entry. A HUSH control provides audio volume reduction intermediate between mute and normal volume levels, obtainable by pressing a HUSH keybutton, or automatically hushed concurrent with a program channel change. Maintaining a televisor's necessitous channel 3 or 4 selection when used in conjunction with a cable box, VCR or other intermediate device is assured by concurrently sending a reiterative channel 3 (or channel 4) tuning command to the televisor whenever a program channel change command or other function signal is dispatched to the cable box, VCR or other television signal tuning apparatus.
