Abstract: An exemplary embodiment of a testing device for testing a pulling force includes a shell having a test platform, a load sensor mechanism, a control system, a drive and transmission mechanism and a material clamping mechanism. Two portions of a test object are clasped by the load sensor mechanism and the clamp. When the load sensor mechanism is driven to move further away from the clamp via the drive and transmission mechanism, a pulling force perpendicular to the test platform is generated between the two portions of the test object. The load sensor mechanism detects the pulling force and feeds back the detection to the control system.

Abstract: The present invention relates to a musical pillow. The music pillow includes a body, a pillow core defining a first receiving cavity corresponding to a users' head, and a music player device. The body includes a first base, and two sidewalls extending from two opposite sides of the first base. Two free ends of the two sidewalls face each other to define a body opening therebetween. The first base and the two sidewalls cooperatively define a receiving space. The pillow core is received in the receiving space, while the first receiving cavity is communicated with the body opening. The music player device includes two speakers positioned on the sidewalls respectively and a playing unit positioned in the first base. The speakers are electrically connected to the playing unit.

Abstract: A depth checking device includes a body member, a pressing member, a checking member and an adjustment nut. The body member defines a stepped through hole forming a stopping surface inside. The pressing member includes a first end and an opposite second end. The first end includes a first end surface defining a first opening. The second end defines a second opening. The checking member is mounted in the stepped through hole and includes an indication end adjacent to the first end and a probe end. The indication end includes a second end surface. The adjustment nut is screwed on the checking member and supported by the stopping surface in a position where the first end surface is coplanar with the second end surface and the probe end protrudes from the body member with a protruding length of the probe end same as a designed depth of a fixing hole.

Abstract: An overlay film for covering a touch screen of an electronic device is disclosed. The touch screen is configured for showing a number of icons thereon for receiving user inputs. The overlay film is a thin, transparent layer. The overlay film defines a plurality of through holes corresponding to the shapes and positions of the icons on the touch screen.
