  • Patent number: 8493862
    Abstract: Devices and techniques for overcoming lost packets and avoiding congestion when conducting media conferences over packet switched networks are described herein. To avoid the problem of lost packets, redundant information is inserted into the media stream that permits the receiver to reconstruct any lost packets from the redundant information. Congestion avoidance techniques include adjusting the bitrate of the media stream to find the highest bitrate that can be supported without packet loss due to congestion. When increasing the bitrate to a higher rate, the additional bits can come from the redundant information used for lost packet recovery so that any lost packets caused by network congestion will not adversely affect the bitstream.

  • Patent number: 7556306
    Abstract: A system and method for remote actuation of a vehicle head restraint includes an actuator arrangement configured to effect movement of a head restraint from a raised position to a lowered position. A sensor defines a first area, and is configured to output signals to the actuator arrangement to facilitate movement of the head restraint from its raised position to its lowered position when an object comes within a predetermined distance of the first area. The sensor is disposed proximate a rearview mirror in the vehicle such that a user can simultaneously view the head restraint in the mirror and the first area. Remote actuation systems using infrared sensor assemblies such infrared proximity sensors are disclosed.
