摘要:
A data processing system connected to and controlling an infrared emitter may be utilized to control remote control devices such as video cassette recorders and cassette recorders, allowing the data processing system to program recording by such devices. The data processing system may, for example, be a set-top box located in proximity to remote controlled record/playback devices, relying on line-of-sight or reflected infrared signal transmission, or may be utilized in connection with suitably placed infrared repeaters. The data processing system may also be employed in conjunction with the “server push” network technique, in which a data stream is transmitted to a subscribing client without intervention by the client. The data stream is monitored for user-defined data items. When detected, the data processing automatically controls the appropriate record/playback device to record a broadcast associated with the detected data item.

A method and implementing system is provided in which light beams are projected from a first object upon a second object, and the relationship of the images projected upon the second object is used to provide an indication of the distance between the two objects. In an example, two light beams are projected at a predetermined angle of convergence from a vehicle such that the beams intersect between the vehicle and an object located in the path in which the vehicle is moving, for example, behind the vehicle. The intersection of the beams is selectively adjustable by adjusting the angle of convergence of the projected beams to provide an indication when the vehicle has backed to a position which has been determined to be a safe distance from the object.

A method and system for controlling a display of a data processing system uses first and second wireless position control devices, and a control base unit. The first wireless position control device includes an acoustical transducer for transmitting a first ultrasonic carrier signal upon which X-Y position control and/or action control signals generated by the device are imposed. A second wireless position control device includes and acoustical transducer for transmitting a second ultrasonic carrier signal upon which X-Y position control and/or other action control signals generated by the second control device are imposed. The first and second ultrasonic carrier signals have different frequencies. The control base is associated with the data processing system and includes circuitry for receiving and differentiating the first and second ultrasonic carrier signals to generate decoded display control signals. The display control signals are then used to drive the display device. Two users may thus control the display device simultaneously.

A capacitive sensor input device which includes a movable stud having a top portion for manipulation by a user and a conductive bottom portion is connected to a planar surface, such as a circuit board by means of an elastomeric, adhesive connector. A plurality of sensors are disposed on the planar surface. The respective capacitances between the conductive bottom portion and respective ones of the sensors are used as input to another electronic device, such as a computer, set top box or gaming device. As the capacitances change according to user manipulation of the movable stud elements of the user interface are moved correspondingly.
摘要:
Existing modems and phone lines are employed to allow two or more data processing systems to communicate. The data processing systems communicate utilizing weak signals on top of existing phone line voltage levels. The signals are sufficiently small so as not to be interpreted as a receiver being lifted off hook. The weak signals may automatically adapt to changes in the phone line voltage due to a receiver be lifted off hook or an incoming call being signaled. At a sufficiently high frequency, the data processing systems may communicate while the phone lines are being simultaneously employed for conversation.
摘要:
A method of retrieving Web content from a plurality of Web servers for delivery to a Web client connectable to the World Wide Web via a communication link. The Web client is preferably a data processing system connectable to a television or other conventional monitor to provide low cost Internet access. The method begins by having the user define a set of one or more servers from which content is desired to be retrieved and stored in the cache. These servers are preferably identified by a "list" of favorite Web sites. A test is then made to determine whether a given download period has terminated. Typically, this download period occurs during an "off" period, such as in the middle of the night, to avoid traffic congestion at the Web server sites. If the given download period has not terminated, a determination is then made of an activity level for the communication link as content is being downloaded to the cache from the one or more servers. If the activity level for the communication link is less than a given threshold level, additional requests for content are issued to the cache according to a so-called "fairness policy" that ensures that content from as many sites as possible is downloaded during the download period.
摘要:
A user interface for a computer system display in which a random bounce mode is entered after a period of inactivity by the user. A timer is started at the cessation of user input. Once the timer has reached a predetermined threshold, e.g., one to five minutes, a random bounce mode is entered in which a cursor is continuously moved in the user interface. The system exits the random bounce mode once user input to the computer system is detected.

Methods and arrangements to selectively retrieve Voice over Internet Protocol (VoIP) messages are contemplated. Embodiments include transformations, code, state machines or other logic to selectively retrieve VoIP messages by storing the VoIP messages, associating one or more descriptors with the VoIP messages, and displaying at least some of the VoIP messages. The display may include one or more of the descriptors associated with the displayed VoIP messages. The embodiments may include receiving a designation of a designated VoIP message from the VoIP messages. The embodiments may include retrieving the designated VoIP message. In some embodiments, the designated VoIP message may be played. In further embodiments, the designated VoIP message may be forwarded. In many embodiments, the descriptors associated with the displayed VoIP messages may consist of values of attributes of the displayed VoIP messages. In several embodiments, the attributes may have been received through a user interface. In some embodiments, the displaying may include receiving a change in state of a mouse button. In many embodiments, the designating may include receiving a change in state of a mouse button while a location of a pointer driven by the mouse is associated with the designated VoIP message.

More particularly, hardware and/or software for determining the aggregate segment usage for an electronic document received from one or more users are disclosed. Embodiments include receiving from one or more users an indication of their usage of segments of different versions of the electronic document, aggregating the segment usage indications received, and creating document utilization information for the electronic document. Further embodiments include transmitting the document utilization information to one or more users. Other embodiments include displaying to the user an electronic document and indications of the document utilization information. Electronic documents may be in PDF format, HTML format, etc.
摘要:
A method for utilizing the Monte Carlo method to determine the most efficient arrangement of schedulers for a grid using a Scheduler Optimization Program (SOP). The SOP obtains the schedulers and scheduler timetable from memory and randomly selects a time period and scheduler to analyze. The SOP then uses the selected scheduler to modify the scheduler timetable. The SOP then runs the ROI calculator to obtain a ROI property for the modified timetable. If the ROI property for the modified timetable is greater than the ROI property for the original scheduler timetable, the SOP replaces the scheduler timetable with the modified timetable.
