Power save mode transition using loading translation function

Methods and systems provide an efficient power save mode for multi carrier modems, such as DMT based ADSL and VDSL modems. Fast transitions from power save mode to full operational mode occur, without the overhead of transmitting large quantities of configuration information between the transmitter and receiver. Signal constellation size changes occurring while operating in power save mode to continue to apply once full operational mode is resumed. Multiple power save modes are enabled, each having a different level of power dissipation and crosstalk, both far end crosstalk and near end crosstalk. Power dissipation and crosstalk can thus be graduated on a line, according to a user-requested bit rate.

Circular masking-out area rate determination-based adhesive particle image concave point segmentation method

The present invention relates to a circular masking-out area rate determination-based adhesive particle image concave point segmentation method. The method comprises the following steps of 1) carrying out the image pre-processing to obtain a binary image of a particle image; 2) carrying out the concave point rough detection to obtain an angular point image of the particle image; 3) carrying out the concave point accurate detection, and utilizing an area rate method to obtain all concave points capable of being used for the particle segmentation in a regional contour; 4) carrying out the concave point pairing, wherein the selected concave point pairs are used as the segmentation points of an adhesive particle image; 5) constructing a segmentation line of the particles, obtaining the contour coordinates of individual particles, and combining the coordinates of two segmentation points to obtain the complete particle contour. According to the present invention, by combining an angular point detection method and a method based on concave point analysis, an operand problem brought by purely utilizing the concave point search based on area is avoided; by setting few parameters, a lot of sample training is not needed; at the same time, the segmentation paths can be replanned, thereby being able to adapt to the different shape and size change of the images.

Dual-motor drive cooperatively-controlled under-actuated manipulator

The invention relates to a dual-motor drive cooperatively-controlled under-actuated manipulator. The dual-motor drive cooperatively-controlled under-actuated manipulator is composed of a driving component and two under-actuated finger components. Each finger component is composed of a finger root joint, a middle finger joint and a fingertip joint. Two stepper motors convert rotational motion into linear motion through a leading screw and nut mechanism and push the finger root joints and the middle finger joints of the two finger components. The fingertip joints overcome the torsion spring action by adopting the under-actuated principle. The dual-motor drive cooperatively-controlled under-actuated manipulator is optimally designed according to the characteristics of to-be-grabbed objects which are inconsistent in shape and size or loose, soft, hard and brittle in material and is applied to the occasions where the shape and size change needs to be met, the grabbing force needs to be strictly controlled, and reliable grabbing of the objects needs to be ensured; and the under-actuated manipulator belongs to the technical field of robot and mechanical and electrical integration application and is connected with a robot body and especially suitable for grabbing, sorting and the like of food, agricultural products and light industrial products in the production and logistics fields.
