  • Patent number: 10292891
    Abstract: A robotic walker and associated method are provided. The robotic walker includes a housing containing a control unit operatively connected to a drive unit. The drive unit is operatively connected to a pair of motorized drive wheels. The robotic walker includes first and second winches, each winch having a strap that can be retracted by its respective winch, each winch is operatively connected to the drive unit, each strap having an end adapted to be removably connected to a pair of leg braces worn by a user. The first and second winches may retract a portion of each respective strap to move the legs of the user forward. A first control button is operatively connected to the control unit. The control unit is configured to operate the robotic walker in at least one control mode and the first control button being operable to start the at least one control mode.

  • Publication number: 20180368260
    Abstract: Provided is a differential wiring method for a high-speed printed circuit board, including the following steps: setting a pre-set impedance required value Z2 of a non-ball grid array (BGA) region, determining the width w2 of the second differential wire (210) and the distance d2 between the two second differential wires (210) according to the pre-set impedance required value Z2; calculating the width w1 of the first differential wire (110) and the distance d1 between the two first differential wires (110), according to the distance s1 between two adjacent rows of bonding pads in a BGA region bonding pad array and the minimum processable distance s2 between the bonding pad and the first differential wire (110), where w1 and d1 should satisfy 2w1+d1?s1?2s2, while further calculating w1 and d1 according to a differential characteristic impedance formula; arranging the two first differential wires (110) disposed oppositely to each other in the BGA region according to the determined d1, and arranging the two secon

  • Patent number: 8964169
    Abstract: The invention relates to the topographic technique field, and provides a ranging method and a system, wherein the ranging method comprises the following steps: modulating measured beam, by a modulated signal of which the frequency is continuously changed over time; emitting the modulated measured beam to a measured object; receiving the reflected measured beam and converting the beam into the measured signals; and comparing the frequency of the modulated signal generated when the measured beam is received with the frequency of the measured signals, thus determining the measured distance.

  • Patent number: 7815935
    Abstract: An orally disintegrating formulation and its preparation are provided. The orally disintegrating formulation comprises an effective amount of a pharmaceutically active ingredient and a matrix, wherein the matrix contains an amino acid and pullulan. The orally disintegrating formulation can disintegrate rapidly in oral cavity and be taken without aid of water; Moreover, the formulation has a low hygroscopicity, so that the requirements for storing or producing the formulation is decreased, and the storage life is elongated to facilitate the administration by a patient and the preparation of the protein and vaccine drugs.
