Abstract:
A distant multipoint remote control device and a system for allowing users to exercise multipoint control over an electronic apparatus at a remote end are introduced. The distant multipoint remote control device comprises at least two sensing modules for sensing users' operation and a remote controller independent of the two sensing modules for sending to the electronic apparatus a control signal serving as multipoint mobile information, such that the electronic apparatus performs a corresponding control operation and displays a corresponding result on a screen. The distant multipoint remote control device and system not only render users' control convenient but also enable accurate response to users' control behavior.
Abstract:
A stencil for printing solder paste on a printed circuit board improves an assembly process, cuts production costs, and saves storage space. The stencil (2) is coupled to a fixing frame (1) having a plurality of fixing portions (81) and a motor unit (13). The motor unit (13) generates a plurality of pulling forces (223). The stencil (2) includes a solder paste printing region (21) and a plurality of fixing regions (22). Vias (211) are disposed in the solder paste printing region (21). The directions of the pulling forces (223) are coplanar with the solder paste printing region (21). The edge of the solder paste printing region (21) extends outward to define the fixing regions (22). The fixing regions (22) are movably fixed to the fixing portions (81) and bear the pulling forces (223) to flatten the solder paste printing region (21) of the stencil (2).

The system and method enable detection whether a handheld electronic device is set to a predetermined power consumption state whereby the handheld electronic device operates in a power supplying state of a standby battery and whether a main battery of the handheld electronic device is disconnected, allowing a user to change the main battery without shutting down the handheld electronic device and thereby saving time.
Abstract:
A method for measuring speed involves calculating and measuring speed of an object based on a distance and a time obtained by a method for measuring distance and a method for measuring time, respectively. The time between distance measuring sessions is obtained using the cycle number of a reference signal based on a clock mask synchronous with the distance measuring sessions. The time is corrected according to a plurality of phase shift signals generated based on the reference signal. An error of the time is minimized by increasing the quantity of the phase shift signals. The method enhances the accuracy of the measured time between distance measuring sessions, speeds up speed measurement, and reduces the required circuit areas. A system for measuring speed is further introduced for use with the method.
