Abstract:
An anti-theft device with a trigger applied in a portable electronic device is provided, which has a trigger electrically connected with a trigger unit selectively. When the trigger is separated from the trigger unit, a sensing element begins to carry out the sensing operation, and the portable electronic device is put into a power saving mode. When the sensing element senses that the electronic device has been moved, it transmits a signal to a processor. Meanwhile, the portable electronic device and an alarm unit of the trigger will be enabled simultaneously, making a sound to warn the user.

An ultrasonic sensor includes a casing body and a piezoelectric element. The casing body has a base wall and a surrounding wall that cooperates with the base wall to define an interior space. The base wall has a top surface and a bottom surface. The top surface has a first section, a second section that extends between the first section and the surrounding wall, and a connecting section interconnecting the first and second sections. A distance between the second section and the bottom surface is larger than that between the first section and the bottom surface such that the connecting section and the first section cooperate to define a recess. The piezoelectric element is confined in the recess.

Abstract:
An ultrasound transducer has a cup-shaped casing. The cup-shaped casing has a sidewall. A cross section of an inner surface of the sidewall being perpendicular to a central axis of the ultrasound transducer substantially shows a dumbbell-shaped contour. The dumbbell-shaped contour has a pair of opposite straight-line sections being substantially parallel to a longitudinal axis of the dumbbell-shaped contour and a pair of opposite arc sections being located respectively at two ends of the longitudinal axis of the dumbbell-shaped contour and respectively forming two enlarged portions of the dumbbell-shaped contour. Two ends of each arc section of the dumbbell-shaped contour respectively joint the straight-line sections through two curve sections and each curve section is connected to one end of the arc section and one straight-line section. At least one enlarged area of a dumbbell-shaped surface of an inside bottom surface has a recessed portion.
Abstract:
The present invention relates to a heat-conducting module and a method for manufacturing the same. A hollow aluminum tube (110) is put on a corresponding heat pipe (111) to form an aluminum-skinned heat pipe (11). Then, one or more aluminum-skinned heat pipes (11) are disposed in a casting space (22) of a die casting mold (2). Molten aluminum materials are filled in the die casting space (11) of the die casting mold (2) to form a heat-conducting module (1). By using a die casting process, molten aluminum materials are used to cover at least one aluminum-skinned heat pipe (11), thereby finishing the heat-conducting module (1).
Abstract:
The present invention discloses a method for preparing a zinc oxide (ZnO) nano rod substrate. First, a layer of ZnO nano particles was sputtered on the substrate and the ZnO nano rods were grown with the hydrothermal reaction on this substrate. Repeatedly proceeding the hydrothermal reaction can obtain a higher aspect ratio of the ZnO nano rods. According to this method, highly orientated ZnO nano rods will be prepared. The ZnO nano rods possess very high surface area and provide very effective pH tuning ability. The growth of ZnO nano rods on the plastic and fiber substrate were also prepared to increase the applicability.
