The invention relates to a synchronizing system for synchronously lifting a nursing bed backing plate and an intelligent wheelchair backing plate of a robot nursing bed. The synchronizing system comprises an infrared transmitting module, an infrared receiving module, a nursing bed control module, an intelligent wheelchair control module and push rod motors, the infrared transmitting module comprises three infrared transmitters, the infrared receiving module comprises three infrared receivers, the nursing bed control module is in communication connection with a nursing bed push rod motor, the infrared receiving module is in communication connection with the intelligent wheelchair control module, and the intelligent wheelchair control module is in communication connection with a wheelchair push rod motor. According to a synchronizing method, by the aid of the principle of a pendulum clock, the states of the three receivers of the infrared receiving module are respectively acquired, so that the three receivers can be correlated with the three transmitters, and the backing plates of an electric wheelchair and a nursing bed are kept parallel. By the aid of the synchronizing system and the synchronizing method, the intelligent wheelchair backing plate and the nursing bed backing plate are synchronously lifted, and the nursing bed and the electric wheelchair can be synchronously lifted and flattened without communication.

An automatic tuning system for pendulum clocks provides for a separable magnet and ferromagnetic attractor, one positioned on the pendulum and one positioned off of the pendulum and adjustable to change the separation between the two. The magnetic attraction between these elements serves to simulate a changing gravitational force fundamentally affecting pendulum period.

The invention provides a mechanical pendulum clock comprehensive parameter testing method. The method comprises the steps that 1), a sensor measuring head, and a controller or a PC host are provided; the sensor measuring head is connected with the controller or the PC host through a data line; 2), the pendulum period and the pendulum amplitude of a sensor testing pendulum bob are utilized and transmitted to the controller or the PC host through the data line, and the controller or the PC host internally processes and calculates the pendulum period and the pendulum amplitude, and displays and stores processed and calculated period and pendulum amplitude values; 3), standard data of the period and pendulum amplitude values are built in the controller or the PC host, after testing is stopped, the processed and calculated period and pendulum amplitude values are called out and compared with the standard data for carrying out fault analysis and yield statistics. The testing method has the advantages that period testing is accurate, the test data are analyzed and stored, a plurality of movements are tested at the same time, and the method is suitable for testing the movements in batches for movement manufacturers or testing the single movement fast for retailers and maintainers.

Electrochemical reaction of the new type secondary lithium ion battery includes two sets of mechanism: (1) electrolyte is active material of containing active ions with variational valence; under action of catalyst, active ions in electrolyte generate change of reversible chemical valence on surfaces of positive and negative poles so as to release or absorb electrons; (2) lithium ions do movement in pendulum clock type between positive and negative poles, and M chemical valence of active ions at positive pole is changed as well. The two parts of electrochemical reaction can be taken place at same time, or taken place successively as changed dependent on different charging and discharging conditions. Comparing with current lithium ion battery, the disclosed battery can raise 60% discharge capacity. Energy density of weight reaches to 280Wh/kg, and energy density of volume reaches to 740Wh/kg.
