Abstract:
A test device for testing a circuit board includes a base, a conveying platform, a driving unit, a connecting element, and a testing unit. The base has an operating space from above. The conveying platform is hinged to the base at a variable gradient, communicates with the operating space, and has thereon a carrier movable toward or away from the operating space as needed and configured to carry the circuit board. The driving unit is connected to the conveying platform and configured to drive the carrier to move. The connecting unit is connected to the conveying platform and the driving unit. The gradient of the conveying platform varies when the driving unit drives the carrier to move and thereby moves the connecting unit. The testing unit is movably disposed at the base and has at least one test terminal capable of approaching the operating space and testing the circuit board.
Abstract:
A circuit board with double-sided universal circuit layout for laying out electronic components has a first side with a first circuit layout thereon and an opposing second side with a second circuit layout thereon; hence, the first circuit layout and the second circuit layout are disposed on the opposing sides of the circuit board, respectively. The first circuit layout and the second circuit layout feature electronic circuits having the same function, thereby allowing users to selectively install the electronic components at one of the first circuit layout and the second circuit layout as needed and still have access to the electronic circuits having the same function. A layout method for use with the circuit board with double-sided universal circuit layout is further introduced.
Abstract:
A hinge, configured to be stably positioned by a simple mechanism and advantageously characterized by ease of installation and uninstallation, includes a first connection member and a second connection member. The first connection member includes a first fixing unit and a support unit. The first fixing unit has a first fixing side and a connecting side. The support unit is connected to the connecting side, and has a cylindrical receiving chamber and a via in communication with the cylindrical receiving chamber. The via is penetrable by a rod-shaped tool. The second connection member includes a second fixing unit and a post connected to the second fixing unit. The second fixing unit has a second fixing side. The post is removably disposed in the cylindrical receiving chamber and has a positioning hole for receiving an end portion of the rod-shaped tool when aligned with the via.
Abstract:
A circuit system layout method for laying out a circuit system has a standby power supply unit. The circuit system includes a core circuit set and a non-core circuit set and operates on power supplied by a power source. The core circuit set is still enabled to finalize a temporary process with the power supplied by the standby power supply unit upon an unexpected interruption of the power supplied by the power source. The core circuit set is connected to an energy storing element for storing and discharging the power, and connected to a one-way element for ensuring that the power stored in the energy storing element is supplied to the core circuit set only. The core circuit set performs the temporary process even when the power source does not enable the circuit system to operate. The circuit system is further provided.
Abstract:
The electrostatic protection device for using in the production lines is provided with at least two circuits on production line. The production line is connected to a grounding end via a first circuit and configured to release static electricity. The production line is connected to the grounding end via a second circuit. Once a production line gives a feedback to indicate that static electricity cannot be released from the production line through the first circuit, and the second circuit will instantly give a failure warning. The feedback mechanism for electrostatic protection works without performing any automated detection operation on the production line. Hence, electrostatic protection provided by the electrostatic protection method and device is advantageously characterized by giving an alert to warn of static electricity release failure efficiently and instantly.
Abstract:
A triggering control device for enabling a data collection host assembled on it to execute a corresponding function action comprises a Bluetooth communication module, a control module, a power supply module and a housing containing the foregoing components. The Bluetooth communication module for communicating the triggering control device is controlled by the control module to drive the Bluetooth communication module to output a triggering signal, and the data collection host is enabled while receiving the triggering signal. Thereby, the triggering control device enables the data collection host to proceed a functional action by the Bluetooth communication module, so as to solve the contact fault or interference problem of the prior art.
Abstract:
A liquid crystal module comprises at least a liquid crystal panel with a display side and a liquid crystal side corresponding to each other, wherein at least one portion of the liquid crystal side is a heating portion, such that the heating portion can be driven to heat the liquid crystal side when the temperature of the environmental is under a liquid crystal working temperature. In addition, a liquid crystal anti-freeze method for the liquid crystal module is disclosed.
