  • Publication number: 20240024535
    Abstract: An orthopedic implant having a metal surface and a calcium phosphate layer disposed on at least part of the metal surface is described. The calcium phosphate layer has an average crystallite size of less than about 100 nm in at least one direction and dissolves for more than 2 hours in vitro. The calcium phosphate layer is substantially free of carbonate. The coating, which is formed on a sodium titanate surface, has increased shear strength and tensile strength. The coating is formed by a solution deposited hydroxyapatite process under inert conditions. The pH of the solution varies by less than 0.1 pH unit/hour during coating formation.

  • Patent number: 10809415
    Abstract: The present disclosure relates to an imaging device for use in vehicle security check and a method therefor, and belongs to the field of security check. The imaging device for use in vehicle security check includes: a radiation source device including a first ray unit configured to emit a first ray beam by a first predetermined spread angle to allow the first ray beam to penetrate a first part of a vehicle to be inspected passing through an inspection lane at a preset speed; and a detector device including a first detector unit arranged corresponding to the first ray unit, and configured to receive the first ray beam. The radiation source device is at least partially arranged on the road surface of the inspection lane, and the first detector unit is arranged at a first side of the inspection lane.

  • Patent number: 10761236
    Abstract: Disclosed is a self-propelled container and/or vehicle inspection device, comprising: a rack, a power supply apparatus, a radiation source, a detector cabin, at least two driving motors, and a controller. A fixed beam, a first vertical beam, a transverse beam and a second vertical beam of the rack are fixed to one another; the bottom of the second vertical beam is rotatably mounted with a swing beam forming a balancing suspension. Where a road surface below the device is uneven, the swing beam correspondingly rotates relative to the second vertical beam so as to keep two wheels on the swing beam in close contact with the ground all the time. In the device, a cab of the inspection device is dispensed with, thus staff is not required to drive within the cab and any anxiety of the staff can be eliminated.

  • Patent number: 10365234
    Abstract: An apparatus and method for quick imaging and inspection of a moving target. The apparatus comprises a passage, a scanning and imaging device (106), a first position sensor (101), a second position sensor (103), and a control unit (105). The control unit (105) powers on an electron induction accelerator in the scanning and imaging device (106) to make the electron induction accelerator enter a standby state when the control unit (105) receives from the first position sensor (101) a detection signal indicating that a moving target (100) enters the passage, and controls a beam emitting time point and a beam emitting mode of the electron induction accelerator to correspondingly inspect different parts of the moving target (100) when the second position sensor (103) detects that different sections pass through a radiation scanning area.
