  • Patent number: 12430919
    Abstract: Systems and techniques are described for suppressing false positive notifications for detected objects. In various examples, first bounding box data indicating a detection of a first class of object in a first frame of image data may be received from an object detector. Second bounding box data indicating a prior detection of the first class of object in a second frame of image data may be determined. A first value representing a similarity between the first bounding box data and the second bounding box data may be determined. A notification associated with the detection of the first class of object in the first frame of image data may be suppressed based at least in part on the first value.

  • Publication number: 20140134930
    Abstract: A deburring device, for removing burrs off an inner sidewall of a hole of a workpiece, includes a mounting seat, a first driving member, an elastic coupler, a cutter, a polisher assembly, an elastic coupler, and a controller. The first driving member is mounted on the mounting seat. The cutter is connected to the first driving member by the elastic coupler. The polishing assembly is assembled to the mounting seat and arranged opposite to the cutter, in which the controller is electrically connected to the first driving member and the polisher assembly. The controller controls the cutter to enter the hole of the workpiece and mill the inner sidewall of the hole of the workpiece to remove burrs off the workpiece, the polishing pad moves to remove burrs generated by the cutter.

  • Publication number: 20130000138
    Abstract: A drying system positioned after a foregoing workstation or system for drying workpieces, includes a transport belt for the workpieces to be positioned on; and at least one oven including a main body and a drying member positioned on top of the main body for heating the air in the oven. The main body of the oven includes a base and an air guiding member positioned on the base, and the base and the air guiding member cooperatively define a chamber running through the at least one oven. The transport belt passes through the foregoing workstation and through the chamber. The integration of the drying system with other manufacturing workstations or systems may save time and labor used for transporting workpieces in between drying and other manufacturing steps. The disclosure also provides an oven utilized in the drying system.

  • Publication number: 20120273249
    Abstract: The present invention relates to a cable having weldable shield and includes an insulating plastic jacket being a hollow tube made of an insulation material, such as PVC, PE, XLPE or PU; at least one core wire being correspondingly located in the insulating plastic jacket to axially extend therethrough for power or signal transmission; and a shield being correspondingly provided inside the insulating plastic jacket to axially extend therethrough and being located outside the core wire for shielding electromagnetic wave. The shield can be a braided shield formed by braiding strands of wires on a multi-carrier wire-braiding machine, of which the number of carriers can be determined according to actual need. And the wires on at least one of the carriers are weldable wires.
