Abstract: A thermo sensor assembled to a unit under test has a metal plate, a passive component, and a package. The metal plate has an installation socket and at least one cable tray. The installation socket has a flat conducting base. The passive component has a main body mounted in the installation socket and at least one cable respectively mounted in the at least one cable tray and electrically connected to both the main body and the metal plate. The package integrally encapsulates the metal plate and the passive component. The conducting base is revealed outside the package and directly contacts the unit under test. Therefore, the passive component has a rapid and precise response to heat, and the thermo sensor can be applied to various positions and can get accurate readings without being interfered by the external environment.

Abstract: The present invention relates to adjustable desks and chairs for audiovisual classrooms. It comprises a turntable, at least a desk and at least a chair. The turntable is installed on the floor of an audiovisual classroom. The desk is installed on the turntable. The chair is installed on the turntable and in proximity to the desk. The turntable can rotate the desk and the chair together to any desired angle, thereby increasing the convenience of using an audiovisual classroom.

Abstract: The invention provides a support apparatus capable of supporting a monitor. The support apparatus includes a mounting base, a first frame mounted on the mounting base, a lock member, and a second frame. The first frame thereon defines a first direction and a second direction perpendicular to the first direction. The first frame includes a through hole along the second direction, a slide extending along the first direction, and a slot. The lock member includes a columnar member and a release part. The release part is disposed to pass through the through hole, and an end of the columnar member is disposed limitedly and movably in the slot. The second frame is disposed movably on the slide, and includes a hook. When the hook engages to the columnar member, the release part can be driven to disengage the columnar member from the hook.

Abstract: The invention provides an adjustably-tiltable supporting apparatus which is capable of supporting an object, and it includes a shelf member, a supporting member, a friction device, and a resilient member. When the tilt of the object is adjusted, the supporting member rotates relative to the shelf member so that the outer side of supporting member slides relative to a friction member of the friction device to generate a friction which balances a difference between a torque generated by the weight of the object and an elastic force generated by the resilient member so as to fix the tilt.

Abstract: Supports for electronic devices are provided. A support includes a main body situated on a base surface, a longitudinal frame, two rails, and a connection mechanism. The longitudinal frame is disposed at a center of the main body. The rails are formed on opposite sides of the frame. The connection mechanism connects an electronic device and movably connects the rails.

Abstract: An electronic device and a rotating structure thereof. The rotating structure comprises a base, a shaft, a rotating assembly, and a movable assembly. The shaft comprises a first groove, and is disposed on the base. The rotating assembly comprises a second groove, and is disposed on the shaft to be rotated among a first position, a second position, and a third position. The movable assembly comprises an engaging portion, and is disposed in the shaft to be moved between a fourth position and a fifth position. The engaging portion is located in the first groove. When the movable assembly is in the fourth position, the rotating assembly is between the first position and the second position. When the movable assembly is in the fifth position, the rotating assembly can be rotated to the third position.

Abstract: A thermal imaging system for detecting cracks and defects in a structure. An ultrasonic transducer is coupled to the structure through a malleable coupler. Ultrasonic energy from the transducer causes the defects to heat up, which is detected by a thermal camera. A control unit is employed to provide timing and control for the operation of the ultrasonic transducer and the camera.

Abstract: A thermal imaging system for detecting cracks in a tooth. An ultrasonic dental cleaning tool is used to transmit ultrasonic energy through a jet of water to the tooth that causes cracks in the tooth to heat up. A thermal camera is used to detect the thermal radiation emitted by the heated cracks. The ultrasonic energy is in the form of a pulse where the frequency of the ultrasonic signal is substantially constant within the pulse. The control unit is employed to provide timing and control of the operation of the dental cleaning tool and the camera.

Abstract: A thermal imaging system for detecting cracks and defects in a component. An electromagnetic acoustic transducer (EMAT) is coupled to the component, and introduces pulsed sound signals therein. The sound signals cause the defects to heat up. The IR radiation from the heated pulses is detected by a thermal camera. The amplitude of the pulsed signals are substantially constant, and the frequency of the pulsed signal can be changed within each pulse. A control unit is employed to provide timing and control for the operation of the EMAT and the camera.
