  • Patent number: 9307295
    Abstract: Mechanisms are provided for allowing a user to linearly or non-linearly discover and navigate media content including live events. A smart timeline includes panels of event information, previews, images, etc. Moving ahead allows discovery of future live media content and events and uncovers mechanisms for setting notifications and reminders. Moving back in time allows discovery of past events and mechanisms for replaying past video and audio content. Event navigation mechanisms can be integrated with calendaring applications to post and select events discovered using event navigation mechanisms.

  • Publication number: 20140237425
    Abstract: A system, method and architecture of using context in determining a response to user interaction with a device, such context may be context of content being output by the device, the device's context, the user's content, or some combination of contexts. In accordance with one or more embodiments, a response may comprise a menu the content of which, e.g., one or more user-selectable actions or options, can be determined based on a determined context, or contexts, or a determination may be made to provide a response other than an option menu, which determination may be made based on a determined context or combination of contexts. As yet another alternative, a determination may be made to provide a response that includes a menu, the content of which is determined based on one or more determined contexts, and another response, such as an answer identified based on one or more determined contexts.

  • Patent number: 7456746
    Abstract: A phase shifting diode detector system for an RFID reader. Quarter-wave delay circuitry is coupled between a forward transmitted signal of the RFID reader applied at a first end of the delay circuitry, and a reflected signal returning from an RFID tag applied at a second end of the delay circuitry. The system includes a pair of diode detector bridges, each comprising a series-coupled diode pair configured such that diode polarities in each bridge are reversed relative to the output thereof, to produce opposite rectified signal output polarities. An input to each of the bridges is capacitively coupled, from the junction between each said diode pair, to a respective opposite end of the delay circuitry.

  • Publication number: 20070206797
    Abstract: A Radio Frequency Identification (RFID) security system having a client, that includes a computerized system, at least one RFID tag, and a RFID reader. The computerized system and RFID reader employ a first security protocol and the RFID reader and RFID tags employ a second security protocol for communications. The security protocols permit encryption and/or authentication, and use either the same key exchange algorithms, the same encryption algorithms, and/or related keys to provide seamless communications within the RFID security system.

  • Publication number: 20060238305
    Abstract: Systems and methods for configuring a RFID tag reader based upon one or more aspects of an environment of the RFID tag reader are disclosed. In one embodiment, a tag reader is deployed into an environment that includes readable RFID tags capable of storing dynamic data, and a characteristic of the environment of the tag reader is identified. Based upon the identified characteristic, the configuration of the tag reader is adjusted. In variations, the tag reader is configurable based upon information received from RFID tags. In another embodiment, a configurable RFID tag reader includes a processing portion that sends a first signal to each of a plurality of RFID tags. The processing portion receives information from at least one of the plurality of RFID tags, and adjusts a configuration of the RFID tag reader based upon at least a portion of the information.

  • Patent number: 5894962
    Abstract: This present invention relates to a soda bottle cap having a shell with a spout and a flexible top, and a seal that has an opening through which liquid can flow out when the flexible top is pressed down. With the structure of this soda bottle cap it is possible to release the carbonated liquid from the soda bottle using the high pressure of CO.sub.2 gas inside. When the flexible top is pressed down, the seal changes shape and does not block inner hole (6) so that the liquid in the bottle can be pushed out through the tube(12), and then through the center hole(9) of the seal, and then through channels (10) of the seal, and then through the inner hole (6) of the shell, and then through the spout (4) by the inner hole (6) of the shell, and then through the spout (40 by the high pressure of CO gas in the bottle. When the force on the flexible top (7) is released after use, the flexible top and the seal go back to its original shape.
