Abstract: The present invention relates to a pendulum type energy-saving power generation device, which has a structure that includes a pendulum device, a push-assisting device applying a force to maintain continuous swing of the pendulum device, and an electrical power system that stores the energy converted by the pendulum device and supplies electrical energy required for an operation of the push-assisting device. With the above-described structure, through a swing operation of the pendulum device, the energy generated by the operation is converted into necessary electrical energy that is stored in the electrical power system, with a fraction of the electrical energy being supplied to the push-assisting device to timely provide an assisting push to the pendulum device when the swing of the pendulum device is reduced by friction so as to maintain a continuous operation thereof to continuously generate electrical energy.

Abstract: Realization of sleep and reconnecting functions is developed for network systems which comprise a number of end devices, network path sharing devices and coordinators. End devices and, even, network path sharing devices can be enforced to enter a sleep state at the first preset times and wake up at the second preset times. The two preset times are either assigned offline or adjustable at run time, according to the actual traffic load in the network. When a node wakes up, it checks whether the corresponding parent node is in the active state or not. If the corresponding parent node is not in the active state, the node will find a new parent node to establish a new transmission path.

Abstract: The examination system contains a vibration device, a signal generation device, an audio collection device, and a processing device. A crystalline silicon solar cell is placed on the vibration device. The signal generation device drives the vibration device to vibrate and the crystalline silicon solar cell is synchronously vibrated at a high speed. The audio collection device collects sound from the vibration and the processing device analyzes the sound to determine if the crystalline silicon solar cell has internal cracks or not.
