Title: Dual-igniter airbag control switch
Inventor: LONG STEVEN M
IPC: B60R21/015
Filed: 2000-01-20
Abstract: A motor vehicle airbag system has a switch that allows the driver to selectively disable the system. The airbag system has a module with a plurality of igniters for causing the airbag to inflate, a diagnostic monitor that determines if a collision is occurring and initiates the igniters, and first and second wires extending between each of the igniters and the monitor for conveying signals between the module and the monitor. When installing the switch, each of the first wires is cut, interrupting continuity between the monitor and each of the igniters. The switch is contained in a housing (13) mounted in a passenger compartment of the motor vehicle. A pair of leads for each of the first wires have ends connected to one of the first wires on opposite sides of the point where the wires were cut. Each pair of leads extends into the housing. A manually operable switch (15) is mounted in the housing and has a manual engagement actuator (17) on an exterior of the housing. The switch has a pole for each igniter, each of the poles being connected to one of the leads of each of the pairs. Each of the poles has an on position that connects the leads of each of the pairs together for providing continuity between the monitor and each of the igniters. Each of the poles has an off position that breaks the connection between the leads of each of the pairs. A resistor is mounted in the housing for each of the igniters, each of the resistors being electrically connected to each of the second wires and connected to the switch, so that while in an off position, the poles place the resistors in series between the first and second wires and the monitor. Each of the resistors has an impedance similar to that of one of the igniters so as to avoid a default signal by the monitor while the switch is in the off position.

Title: Frame-level rate control for plug-in video codecs
Inventor: SETHURAMAN SRIRAM
IPC: H04N7/32
Filed: 2000-02-03
Abstract: A variety of different types of video frame encoders can be configured with, e.g., a multimedia processing subsystem, as long as the video frame encoder conforms to the interface protocol of the subsystem. A video controller in the subsystem performs the higher-level functions of coordinating the encoding of the video stream, thereby allowing the video frame encoder to limit its processing to the lower, frame level. In particular, the video controller provides information needed by the video frame encoder to encode the current frame in the video sequence. In addition to the raw image data, this information includes the type of frame to be encoded (e.g., an I or P frame), the currently available bandwidth for encoding the current frame, the time since the previous encoded frame, the desired frame rate, and a quality measure that may be used to trade off spatial and temporal qualities. The video frame encoder either encodes the frame as requested or indicates to the video controller that the frame should be skipped or otherwise not encoded as requested. The video controller can then respond appropriately, e.g., by requesting the video frame encoder to encode the next frame in the video sequence.
