An impacting testing device is provided. The impacting testing device comprises a first platform, a second platform, a plurality of first suspension devices, at least one impact assembly and a plurality of second suspension devices. The at least one impact assembly is disposed on the second platform and faces the first platform for providing at least one impact force to the first platform, and thus, the impact testing is executed on an object disposed on the first platform.
Abstract:
A testing apparatus for testing a solar panel is provided. The testing apparatus includes at least one sensor, at least one impact hammer and at least one adsorbing element. The testing apparatus adsorbs the solar panel with the at least one adsorbing element and the at least one sensor is disposed on the solar panel. At least one vibration is produced when the at least one impact hammer hits the solar panel. The at least one vibration is received and transformed into at least one digital signal by the at least one sensor. The at least one digital signal is then compared with a database to determine the yield of the solar panel.
Abstract:
A posture sensing alert apparatus is provided. The posture sensing alert apparatus comprises an attachment element, a detecting element, a processing element and an alert element. The attachment element is adapted to attach on a human body. The detecting element is disposed on the attachment element and is adapted to sense a posture change from the human body. The processing element is disposed on the attachment element and connects to the detecting element. The processing element is adapted to output a signal to the alert element in response to the posture change for a predetermined period so that the alert element is adapted to output an alert accordingly.
Abstract:
A method for automatically reducing noises in an earphone using an audio transceiver is disclosed. The audio transceiver includes an audio transmitter, an audio auto-adjusting module, an audio amplifying module, an audio detecting and receiving module, a power set and a manual adjusting button. The method comprises the steps of: receiving external interference audio signals in the audio detecting and receiving module of the audio transceiver; generating mixing frequency signals in the audio auto-adjusting module; the mixing frequency signals having frequencies near the frequencies of the external interference audio signal; a phase difference of about 180 degree from the interference audio signal and amplitudes approximately equal to those of the external interference audio signals; transferring the mixing frequency signals to the audio amplifying module for amplifying the mixing frequency signals; and transmitting the amplified mixing frequency signals so as to cancel the external interference audio signals.

Abstract:
A vibration testing device with a platform, a vibration assembly, a housing and a cooling system is provided. The platform is adapted to hold a test object. The vibration assembly is adapted to force a vibration to the platform. The housing has an inlet end and an outlet end opposite the inlet end. The housing is disposed under the platform and covers the vibration assembly. The cooling system with a fan and an atomizing assembly, and is disposed on the housing. The fan is adapted to generate an airflow. The atomizing assembly is adapted to generate atomized water. The airflow with the atomized water passes through the inlet end, the interior of the housing and the outlet end sequentially to reduce the working temperature of the vibration assembly.
Abstract:
A micro damper device comprising a main body, a cover, a sensor component and a control component is provided. The main body has a first surface, a second surface, a convex and a coil. A current is introduced to the coil to form a magnetic field with a first and a second magnetic pole. The cover has a first end, a second end and a first magnetic component. The sensor component is disposed on a side opposite the convex to measure a first vibration direction of the second surface. The control component is electrically connected between the sensor component and the coil and controls the current for adjusting the polarity and the strength of the first magnetic pole for producing a force between the first magnetic pole and a third magnetic pole, which makes the main body move along a second vibration direction opposite the first vibration direction.
Abstract:
A sound wave testing device is provided. The sound wave testing device comprises at least one sound output unit for providing at least one first sound signal, at least one sound-collecting element disposed above the at least one sound output unit, at least one sound-receiving unit disposed at one end of the at least one sound-collecting element, and an isolating element disposed between the at least one sound output unit and the at least one sound-collecting element, in which the solar panel is disposed on the isolating element. The at least one first sound signal is transformed into at least one second sound signal while passing through the solar panel. The at least one second sound signal is received and transmitted to at least one sound-receiving unit, and the at least one second sound signal is transformed into at least one digital signal for output.
