Abstract: A launch control system for a vehicle having a powertrain includes a transmission configured to selectively perform a transbrake operation to temporarily lock the transmission to hold the vehicle stationary while an engine throttle position is increased for a vehicle launch, an actuator configured to initiate a transbrake creep operation, and a controller in signal communication with the transmission and the actuator. The controller is configured to (i) command the transmission to perform the transbrake operation, (ii) receive a signal from the actuator indicating a request to initiate the transbrake creep operation, and (iii) command the transmission to momentarily disengage the transbrake for a predetermined period of time to enable the vehicle to perform the transbrake creep operation and move the vehicle forward while maintaining the increased engine throttle position.

Abstract: Systems and methods for multicast stream mapping are disclosed. In one embodiment, a computer-based system to map multicast streams in a multicast network comprises a processor and a memory module coupled to the processor and comprising logic instructions stored on a tangible computer readable medium which, when execute by the processor, configure the processor to obtain a list of all access routers in the multicast network, create a process thread for each access router in the multicast network, collect multicast stream data from each access router in the multicast network, and present the multicast stream data in a report on a user interface. Other embodiments may be disclosed.

Abstract: An improved video phone which transmits a source image over a standard telephone line in conjunction with audio voice signals is disclosed. The unique initialization protocol allows asynchronous transmission with its short format. The protocol format provides for a hardware preamble for synchronizing a receiver clock, a software preamble for identifying the video image and disabling the audio, automatic gain control adjustment data and amplitude calibration data. The audio portion is disabled by coupling a capacitor across the telephone to effectively short the telephone. The telephone is placed across the bridge circuit which is provided with switches to balance the bridge in both the telephone audio and the video modes. The transmitted as well as the received signal are passed through the same delay equalization circuit, so that half the delay equalization is done before transmission, with the remaining half being done after reception.

The transmitted and received signals pass through the same delay equalization circuit, so that half the equalization is done before transmission, with the remaining half being done after reception. Input and output selectors allow the same circuit to be used. The digital signals are level shifted up prior to being converted into analog, and then are shifted down again to reduce the effects of DC offset.

Abstract: A releasable bolt device 1 for securing an emergency exit door 2 comprises a support structure 3 of box-like form, a bolt member 4 slidably mounted on the structure 3 for movement relative thereto, a compression spring 5 for urging the bolt member 4 away from the door-securing position, a frangible keep member 6, and a plate 7 for retaining the keep member 6 in place whereby its presence maintains the bolt member 4 in a door-securing position. The frangible keep member 6 is weakened locally so that it may be deliberately broken at that locality by manual force applied to it, whereby the bolt member 4 is moved out of its door-securing position by the spring 5.

Abstract: The present invention is a conversational freeze-frame video phone which transmits a source image over a standard telephone line in conjunction with audio voice signals. A camera is used to capture an image to be transmitted and the image is mapped onto an image field of 2,000 to 5,000 pixels. The image field is displayed on a display area of approximately one square inch on a display screen. Digitized data representing the pixels is asynchronously transmitted on a modulated signal in a single burst of less than three seconds duration. Corresponding remote images are asynchronously received, demodulated, and displayed. The transmission of the audio signal is interrupted upon the detection of a video image being transmitted.
