  • Patent number: 8896240
    Abstract: A multifunctional electric tool has a housing, a motor arranged in the housing, a transmission device driven by the motor, a speed controlling device. At least two output shafts which have different dimensions are to be used with the tool wherein the output shaft is used to control the activation of the speed controlling device. The rotational speed of the electric tool may thus be automatically adjusted to match with the rotational speed of the accessory installed on the output shaft.

  • Patent number: 8842161
    Abstract: A videoconference apparatus and method coordinates a stationary view obtained with a stationary camera to an adjustable view obtained with an adjustable camera. The stationary camera can be a web camera, while the adjustable camera can be a pan-tilt-zoom camera. As the stationary camera obtains video, faces of participants are detected, and a boundary in the view is determined to contain the detected faces. Absence and presences of motion associated with the detected face is used to verify whether a face is reliable. To then capture and output video of the participants for the videoconference, the view of the adjustable camera is adjusted to a framed view based on the determined boundary. In the end, active video captured in the framed view with the adjustable camera can be sent to a far-end for the videoconference.

  • Patent number: 8260084
    Abstract: Binary image stitching based on grayscale approximation. In a first example embodiment, a method for automatic binary image stitching of first and second binary images includes several acts. First, the first and second binary images are converted into first and second thumbnail grayscale images. Each thumbnail grayscale image is a lower resolution than its corresponding binary image by a scaling factor. Next, a thumbnail transform is calculated between the first thumbnail grayscale image and the second thumbnail grayscale image. Then, a full-size transform is calculated as a function of the thumbnail transform and the scaling factor. Next, the stitched binary image is created by projecting the first binary image onto the second binary image using the full-size transform and combining overlapping portions of the first and second binary images.
