  • Publication number: 20250062617
    Abstract: A power distribution circuit. The power distribution circuit includes an alternating current input end, a direct current input end, an alternating current load input end, a direct current load input end, a switch circuit, a DC/AC converter, a DC/DC converter, and a control unit. The power distribution circuit may convert an alternating current input by a mains system into a stable direct current and a stable alternating current, to provide stable electrical signals for an alternating current load and a direct current load.

  • Publication number: 20230274633
    Abstract: The invention provides a method and system for extracting OD locations of a vehicle on an expressway. The method includes: acquiring mobile phone signaling data and license plate recognition data; preprocessing the signaling data and recognition data; segmenting mobile phone signaling data trajectories to obtain signaling data with a travel order; matching the mobile phone signaling data trajectories against license plate recognition data trajectories, to obtain a vehicle and a mobile phone signaling user corresponding to the vehicle; and extracting a passing time of the vehicle passing through a road section in the license plate recognition data, calculating time differences between the passing time and travel trajectory points of the mobile phone signaling user corresponding to the vehicle, and taking start and end locations of a travel order of mobile phone signaling data in which a minimum time difference is located as OD of a current travel of the vehicle.

  • Patent number: 11306695
    Abstract: The present disclosure relates to a device and a method for swinging power generation and vibration suppression by using arc-shaped wing plates with rough surfaces. The device consists of two parts, namely, a rotary swinging system and a collector system. The rotary swinging system includes a collector riser, steering bearings, nanometer material arc-shaped power generation wing plates, and flexible tail plates. The collector system includes telescopic power generation cylinders, a waterproof electric slip ring, and a waterproof power transmission line. The suppression of energy-consumption-free vortex-induced vibration is realized under the combined action that the nanometer material arc-shaped power generation wing plates divide a flowing space and adjust a flow direction, the nanometer material arc-shaped power generation wing plates drive the flexible tail plates to swing to destroy a tail vortex street, and hemispherical bulges and trumpet-shaped deflector holes disturb a boundary layer around flow.

  • Publication number: 20120040342
    Abstract: Methods for determining resistance to weight loss and susceptibility to binge eating episodes are described. The methods include determination of the presence of a obesity related alleles for a patient at single nucleotide polymorphism sites associated with the genes INSIG2, FTO, MC4R, and PCSK1. The total number of obesity alleles for the patient is indicative of the patient's resistance to weight loss and susceptibility to weight gain following bariatric surgery. The methods also include determining if a patient is homozygous for an obesity related allele at one or more single nucleotide polymorphism sites of the four genes.

  • Publication number: 20060229330
    Abstract: Novel intermediate compounds are disclosed. These compounds are useful in the synthesis of 4-aminopyrimidine-5-one derivatives that inhibit cyclin-dependent kinases, in particular cyclin-dependent kinase 4 (Cdk4). The 4-aminopyrimidine-5-one derivatives and their pharmaceutically acceptable salts have antiproliferative activity and are useful in the treatment or control of cancer, in particular solid tumors.
