  • Publication number: 20070182020
    Abstract: A method of electrically joining a first contact on a first wafer with a second contact on a second wafer, the first contact, a rigid material, and the second contact, a material that is malleable relative to the rigid material, such that when brought together the rigid material will penetrate the malleable material, the rigid and malleable materials both being electrically conductive involves bringing the rigid material into contact with the malleable material, applying a force to one of the first contact or the second contact so as to cause the rigid material to penetrate the malleable material, heating the rigid and malleable material so as to cause the malleable material to soften, and constraining the malleable material to within a pre-specified area.

  • Publication number: 20070176639
    Abstract: An integrated circuit includes first circuitry and sleep transistor circuitry. The first circuitry receives input signals and processes the input signals. The first circuitry also retains data in a sleep state that has low leakage. The sleep transistor circuitry is coupled to the first circuitry and receives a sleep signal that has a negative voltage. The sleep circuitry reduces power consumption of the first circuitry in the sleep state to have low leakage based on the sleep signal while retaining the data in the first circuitry.

  • Patent number: 7216585
    Abstract: An offset printing press includes a first plate cylinder, a first blanket cylinder for selectively contacting the first plate cylinder, an anilox inker for inking the first plate cylinder, and a first motor directly connected to the anilox inker for driving the anilox inker and connected to the first plate cylinder for driving the first plate cylinder. A second print couple has a second plate cylinder and a second blanket cylinder for selectively contacting the second plate cylinder. A second anilox inker inks the second plate cylinder and a second motor directly connected to the second anilox inker drives the second anilox inker and is connected to the second plate cylinder for driving the second plate cylinder. Blanket cylinders are either driven by their own third motor or via gear transmission from the first or second motors.

  • Publication number: 20070094689
    Abstract: In a broadband communications system, e.g., a cable system, programming content can be readily reserved and accessed for viewing using interactive program guides in accordance with the invention. Such programming content may include in-progress programs, future programs and previously broadcast programs which are recorded at a headend in the cable system, and which may or may not have overlapping broadcast times. In addition, the user may reserve programs at a set-top terminal, and may also do so remotely from the terminal through a communications network such as, the Internet, a public switched telephone network (PSTN), a wireless telephone network, etc.

  • Publication number: 20060281303
    Abstract: A method of joining contacts on two chips, each having multiple contacts, to each other involves maintaining a first of the chips at a first temperature, the first of the chips having a rigid electrical contact thereon, bringing a second chip, having an electrical contact that is malleable with respect to the rigid contact and matingly corresponding thereto, into contact with the first such that the corresponding rigid and malleable contacts are brought together, locally raising the second of the chips to a local temperature that is sufficiently high to cause material of the rigid and malleable contact to interdiffuse, interpenetrate or both, but below both a temperature that would cause the material to become liquidus and a fuse temperature, and allowing the second of the chips to cool to at least the first temperature.

  • Publication number: 20060278992
    Abstract: A method of physically and electrically joining two chips to each other involves aligning an electrically conductive contact of a first chip with a corresponding electrically conductive contact on a second chip, the electrically conductive contact of the first chip being a rigid material and the electrically conductive contact of the second chip being a material that is malleable, bringing the aligned electrically conductive contact of the first chip into contact with the corresponding electrically conductive contact on the second chip, elevating the contact of the chips to a temperature that is below a liquidus temperature for both the rigid material and the material that is malleable while applying pressure to the chips so as to cause the rigid material to penetrate the malleable material and form an electrically conductive connection, and, following the forming of the electrically conductive connection, cooling the contacts to an ambient temperature.

  • Publication number: 20060218604
    Abstract: Methods and apparatus for providing content to users of a network that can be selectively recorded via the user's equipment. In an exemplary embodiment, the network comprises a hybrid fiber coax (HFC) network, and on-demand (OD) sessions are used to provide high-speed download of the requested content to the users. The user's equipment (e.g., set-top box) is equipped with a high-density recording device which can both record the content onto a selected medium (e.g., DVD) and optionally provide copyright protection via one or more means such as limiting the number of copies that can be made, and/or digital watermarking. The network operator can also restrict the establishment of the on-demand sessions and/or release of the content to subscribers based on parameters including prior purchase of the content by the user, and the timing of the release of the same content via other distribution channels such as rental and retail.

  • Publication number: 20060184967
    Abstract: A favorites list of program channels which a cable TV user likely prefers is generated automatically, from which the user may select a program channel to watch. Each program channel in the favorites list is identified based on a measure of the duration in which the program channel is continuously tuned to. In an embodiment, this measure varies nonlinearly with such a duration. The favorites list may further comprise sublists of program channels which may correspond to different periods of a day, week, etc.

    Abstract: Methods and apparatus for delivering data over extant infrastructure within a content-based network. In one embodiment, the network comprises a cable network, and the infrastructure comprises that nominally used for on-demand (OD) services such as VOD. The method includes the allocation of dedicated end-to-end network resources via a “session request, as well as data flow control and packet size adaptation, by a data server based on feedback from the requesting/receiving client device (e.g., DSTB) within the network. Mechanisms for retransmission requests for error recovery are also provided.

  • Publication number: 20060105835
    Abstract: A pneumatic prize dispensing system for an arcade game. The game includes a pneumatically-controlled method of suspending and controlling the movement encapsulated prizes within a vertically-oriented transparent tube by means of differential air pressure. A player controls the vertical position of the prize by means of a pneumatic control valve. The object of the game is to control the position of the prize capsule to match a target position zone presented to the contestant via a set of visual cues for a predetermined period of time. The game dispenses the encapsulated prize or alternatively, prize tokens, if the game-winning criteria are achieved.

  • Publication number: 20060103660
    Abstract: Methods and apparatus for generating images, compressing image data, decompressing image data, and processing the decompressed image data so that it can be used by a rendering circuit of a device, e.g., a set top box, are described. Images are generated in the native format used by the rendering circuit of the device which will ultimately control the display of the image avoiding the need to perform processing associated with converting color component information from one format to another. Uncompressed image data is arranged in a file with color component values being grouped separately from alpha values to facilitate compression by a standard file compression technique. The file is compressed using a conventional file compression operation. The compressed image file is decompressed when needed and the alpha data and color component data is reorganized so that the color component values and alpha value(s) corresponding to individual pixels are grouped together.
