Abstract: A tool set includes a tool holder, a tool and a tool rack. The tool has a groove unit. The tool holder has a latch unit that engages the groove unit. The tool rack includes a rack body and a blocking member. When the tool holder is moved away from the rack body after the tool is moved into the rack body by the tool holder and after the blocking member moves to a blocking position, the tool is blocked by the blocking member so that the latch unit is separated from the groove unit and that the tool holder is separated from the tool.

Abstract: A digital image enhancer includes a deinterlacing processor receptive to an interlaced video stream. The deinterlacing processor includes a first deinterlacer and a second deinterlacer and provides a deinterlaced video stream. The digital image enhancer also includes a video output processor receptive to the output of the deinterlaced video stream to provide a scaled, deinterlaced video stream. A portable DVD player including the digital video enhancer has a generally thin prismatic enclosure having a first major surface, a second major surface separated from said first major surface, and side surfaces connecting the first major surface to the second major surface. At least a portion of the first major surface includes a video display, and the enclosure includes a DVD entry port such that a DVD can be inserted into the enclosure.

Abstract: A portable DVD player includes a generally thin prismatic enclosure having a first major surface, a second major surface separated from the first major surface, and side surfaces connecting the first major surface to the second major surface. At least a portion of the first major surface includes a video display. The enclosure further includes a DVD entry port such that a DVD can be inserted into the enclosure. A digital processing system within the enclosure includes a decoder, a deinterlacer, and a display controller. The decoder receives signals from a DVD inserted into the enclosure to provide a decoded, interlaced video signal, the deinterlacer converts the interlaced video signal to a deinterlaced video signal, and the display controller uses the deinterlaced video signal to provide progressively scanned video on the video display. Preferably, the portable DVD player is both mechanically and electronically isolated for physical shocks to the player.
