  • Patent number: 11961892
    Abstract: A semiconductor device and methods of forming the same are disclosed. The semiconductor device includes a substrate, first and second source/drain (S/D) regions, a channel between the first and second S/D regions, a gate engaging the channel, and a contact feature connecting to the first S/D region. The contact feature includes first and second contact layers. The first contact layer has a conformal cross-sectional profile and is in contact with the first S/D region on at least two sides thereof. In embodiments, the first contact layer is in direct contact with three or four sides of the first S/D region so as to increase the contact area. The first contact layer includes one of a semiconductor-metal alloy, an III-V semiconductor, and germanium.

  • Patent number: 8355338
    Abstract: A method of processing sequential information in near real-time data packets streamed over a network includes providing a process running according to a process clock. The process buffers and decodes the streamed data packets. The speed of the process clock is dynamically controlled in accordance with a receipt time value of a data packet. The speed of the process clock is run faster or slower than a system clock.

  • Patent number: 8320364
    Abstract: A method for controlling a real-time media stream between a sender and a receiver. The method includes streaming, from the sender, media packets over a network at a bit-rate, determining at the sender a loss-rate for the streamed media packets not received at the receiver. The sender optionally generates duplicate packets for a selected number of media packets and streams the duplicate packets over the network when the loss-rate is above a first loss-rate threshold, or varies the bit-rate of streaming the media packets over the network when the loss-rate is above a second loss-rate threshold.

  • Publication number: 20110273393
    Abstract: The present invention relates to method and apparatus for receiving and processing one or more inputs from multiple mobile devices. In some embodiments, a mobile device identifies its neighboring mobile devices. Based on the information of neighboring mobile devices for each mobile device, a topology of multiple mobile devices is developed. If an input is provided to a mobile device, the mobile device will determine if the input is a supported distributed event. If the input is a supported distributed event, the mobile device will gather the inputs from other mobile devices and aggregate them into an aggregate input. Based on the aggregate input, an output is generated to control one or more mobile devices in the topology.

  • Publication number: 20080069065
    Abstract: A method of roaming between access points on the same or different wireless networks using a single wireless network interface adaptor. A device will establish a connection with a second wireless network access point while still connected with a first wireless network access point such that the device can concurrently communicate with both wireless access points. During and after connection with the second wireless network access point real-time IP data transfer is maintained with another network device by switching between the first and second access points for concurrently sending and receiving data packets via both access points using a switching strategy based at least in part on a number of the data packets to be send to each network access point. The method also determines when to roam, scans for candidate wireless network access points to connect to and selects the best access point for roaming based on selection criteria.
