Abstract: The present invention is to provide a multifunctional tool set which has functions of wrenches and screwdrivers and is easy to carry and includes a plate, a fixing device and screwdrivers with screwdriver heads in different specifications. The plate has a through hole cut therethrough, and first and second stepped portions, wherein the first and second flat portions are formed on an inside wall of the through hole. The stepped portions correspond in position to the flat portions respectively, so as to form the wrench holes with different imperial and metric dimensions. The fixing device has assembly holes cut therethrough and configured for insertion of the screwdrivers, and a lower portion more forwardly protruding than an upper portion thereof for matching with the through hole. Therefore, the fixing device can be mounted into the through hole by a deformation manner and the screwdrivers are positioned in parallel to both sides of the plate.

Abstract: A moving object tracking apparatus is disclosed.

A moving object tracking method is also provided.

Abstract: The present invention is to provide a double-ended wrench set with identical torque holes, which comprises at least two double-ended wrenches having torque holes of a same configuration and a torque rod comprising a torque body and a torque head perpendicularly connected to the torque body, wherein each said torque hole is located in a wrench body of the double-ended wrench, the torque body has a greater length than the torque head, and the torque head has a cross section identical in configuration to the torque hole and is able to be fitted into said torque hole.

Abstract: A frame dropping method for a video frame and a video sending apparatus are used to perform frame dropping processing on video frames in order to reduce a quantity of dropped frames, enhance video playing smoothness, and improve user experience. A specific solution includes obtaining a video frame sequence of a to-be-sent video, establishing a reference relationship between video frames in the video frame sequence according to a preset criterion, and detecting a data occupation length of buffered video frames in a video sending buffer during a process of sending the video frame sequence, dropping a current to-be-buffered video frame when the data occupation length is greater than a preset threshold, and dropping all video frames in the video frame sequence that reference the current to-be-buffered video frame according to the reference relationship.

Abstract: The present invention is to provide a knife, which includes a blade having one end formed as a tip and having an engaging groove formed on a side adjacent to the other end thereof; a handle having a side concavely provided with an inwardly extending receiving space and an engaging post fixedly provided therein adjacent to one end thereof and having an elastic plate provided therein adjacent to the other end thereof; and a back-lock member having a first end corresponding to the receiving space, a second end being movably abutted by a free end of the elastic plate, and a middle section pivotally connected in the handle. Thus, when the second end is being pressed, the other end of the blade can be inserted into the receiving space and, is then securely engaged with the engaging post through the engaging groove while the second end is released.

Abstract: The present invention is to provide a positioning control mechanism applied to an expandable baton including a first pipe provided with a clamping groove portion on two opposite inner walls thereof and a second pipe inserted into the first pipe and provided with shifting holes on two opposite wall surfaces thereof. The positioning control mechanism includes an activating mechanism and a releasing rod. The activating mechanism is formed by two activating blocks movably positioned in the shifting holes and hooked with each other to form a releasing hole therebetween. The releasing rod is mounted inside the first pipe and, when one end of the releasing rod is inserted into the releasing hole, the outer edges of the activating block can be retracted inwardly and is not inserted in the clamping groove portion, so the second pipe can be retracted into the first pipe and positioned to form a short-rod shape.

Abstract: This application is to provide a knife structure which comprises a handle, a locating main body having an engagement part extended from an end thereof, configured to engage with two engagement slots formed on a blade and having other end connected to the handle, and a poke element pivotally connected to the handle adjacent to the other end of the locating main body and having a push part disposed at an end thereof and a poke part disposed at other end thereof. Under a condition that the poke part is poked to rotate, the push part is inserted into a sunken portion of the locating main body to force the other end of the blade to bend, deform and escape from a state of being engaged, so as to enable the blade to be pulled out in a direction away from the handle.

Abstract: An integrated optical modulator device. The device can include a driver module coupled to an optical modulator. The optical modulator is characterized by a raised cosine transfer function. This optical modulator can be coupled to a light source and a bias control module, which is configured to apply an off-quadrature bias to the optical modulator. This bias can be accomplished by applying an inverse of the modulator transfer function to the optical modulator in order to minimize a noise variance. This compression function can result in an optimized increased top eye opening for a signal associated with the optical modulator. Furthermore, the optical modulator can be coupled to an EDFA (Erbium Doped Fiber Amplifier) that is coupled to a filter coupled an O/E (Optical-to-Electrical) receiver.
