Abstract: A quick coupler for construction machines. An embodiment of the quick coupler comprises a housing with two opposing longitudinal walls, two opposing transverse walls, a top side, a bottom side, and a block cylinder inside the housing. The quick coupler may also comprise a locking device with a locking bolt and a drive device. The locking bolt protrudes from one of the two transverse walls in a locked position. The quick coupler may also comprise a first coupling element having a coupling end section and a second coupling element having a coupling end section hydraulically connected to one another, wherein the second coupling element is arranged on one of the two longitudinal walls of the housing.

Abstract: Certain aspects of a method and system for time based wireless local area network (WLAN) scanning may include controlling scanning of a plurality of wireless access points in one or more WLANs by a WLAN station based on one or more factors comprising power consumed by the WLAN station based on the scanning, and/or a priority level of one or more media packets to be handled by the WLAN station. The information may be acquired for one or more of the plurality of wireless access points in one or more WLANs during the controlled scanning.

Abstract: A method of accommodating aberrant behavior in wireless devices in a wireless network includes the steps of establishing communication with at least one wireless device, monitoring signals received from the at least one wireless device, determining characteristics of the at least one wireless device based on the monitored signals, comparing the determined characteristics with prescribed characteristics for wireless devices exhibiting aberrant behavior and altering settings to accommodate the at least one wireless device, when the determined characteristics match the prescribed characteristics.

Abstract: A technique for providing PCI bus mastering compatibility for legacy PCI bus devices which may not support PCI bus mastering RETRY protocols. DLDMM provider software in a device driver for a target device may provide a callback signal at a callback address to DLDMM client software in a device driver for a bus mastering PCI device. The callback address may be used by the DLDMM client software to signal the bus mastering PCI device to suspend operation in the event of an interrupting event. The bus mastering PCI device may then generate in driver software a RETRY signal to the device driver of the target device. If the interrupting event is over, a signal may be sent by the DLDMM provider software in response to the RETRY signal to the DLDMM client software indicating that the bus mastering device may resume operation. The bus mastering device may then resume operation where left off.

Abstract: A method and system for synchronizing audio and video data signals that are in a signal format wherein the audio and video data signals are not interleaved but originate from separate sources and arrive at a constant frame rate. In one embodiment, the audio and video data signals are in an Moving Pictures Expert Group (MPEG) format. Portions of the novel system operate within the hardware of a video processor unit and portions of the novel system operate within a software driver of a computer system that receives the audio and video data signals. Audio and video data signals are referenced by a presentation time stamp (e.g., VPTS for video and APTS for audio) encoded in the data. Using these stamps, the novel system (via the video processor unit) determines if the video signal is ahead or behind the audio signal by a small number of frames, x, and if so, the video processor unit either pauses or skips frames in its video display unit hardware to regain synchronization.

Abstract: A multimedia system including an audio/video decoder/decompresser for decoding/decompressing a compressed encoded audio/video data stream to generate video images for display and audio signals for audible reproduction. The multimedia system includes an integrated system and video decoder with an audio/video synchronization circuit for substantially synchronizing the display of video images with audio playback. Latency between Audio and Video decompression/decoding may be adjusted dynamically by internal hardware. Hardware signals indicating the need to skip or repeat a frame or frames of video or audio data are fed to a hardware circuit which may increment or decrement a latency value accordingly. The latency value is thus stepwise incremented or decremented until no further frame skips/repeats occur. The hardware implementation allows for better matching of latency value to audio and video decoder, frees up software for other tasks and reduces software code requirements.
