PROBLEM TO BE SOLVED: To provide an electrostatic protection method that can obtain an electrostatic protection function for an electronic product without adding an electrostatic protection circuit and other elements, and to provide a structure for an electronic product.SOLUTION: The electrostatic protection structure for an electronic product is applied to an electronic product that has an electronic component 12 provided therein and prevents the electronic component 12 from being damaged by electrostatic discharge. At a portion of a housing 10 of the electronic product that corresponds to the electronic component, a through-hole 11 that communicates with the outside is provided. The length and shape of the through-hole 11 is determined based on the length of an arc 200 generated by electrostatic discharge. The arc 200 generated by electrostatic discharge is prevented from reaching the electronic component 12 by the through-hole 11 that is equal to the arc 200 in length or larger than the arc.

Abstract:
A message pushing system, a client equipment and a message pushing method thereof are provided. In the method, the client equipment resides in a local network, and the client equipment registers with a local server and a remote server via the local network and an external network. Then, the client equipment publishes messages or receives subscribed messages via at least one of the local network and remote network base on a publishing/subscribing mechanism. Accordingly, no matter whether the client equipment can connect to the external network, if another client equipment can connect to any server via the local or external network, published messages can be transmitted to the client equipment or another published message from the client equipment can be successfully received.

Abstract:
A method for starting an application smartly and power-efficiently is applicable to a portable electronic device installed with an application and hardware. The portable electronic device receives a voltage generated from a power supply, such as an internal battery power or an external power. After the portable electronic device has started, a connection between the application and the hardware is created. Upon detection that the voltage originates from the external power, the application is executed based on a preset schedule to start the hardware corresponding to the application until it is detected that the source of the voltage has been switched to the internal battery power. Upon the detection that the source of the voltage has been switched to the internal battery power, a user determines whether to change the state of use of the hardware, thereby rendering the portable electronic device smart and power-efficient.

A data processing device is provided, which includes: a main battery that supplies main power to the data processing device; a backup battery that supplies backup power to the data processing device when the main battery does not supply the main power to the data processing device; a receiving module that receives a standby command or a recovery command; a standby module that enables the data processing device to operate in a standby mode when the receiving module receives the standby command, allowing replacement of the main battery; a recovery module that determines, when the data processing device is operating in the standby mode, whether the main power is enough to enable the data processing device to operate normally, and enables the data processing device to operate in an operation mode when the main power is determined to be enough to enable the data processing device to operate normally.
Abstract:
A method for measuring distance involves calculating a distance based on light speed and a time taken by an optical signal to travel to an obj ect and return therefrom. The method includes calculating a time based on a cycle number of a reference signal under a clock mask synchronized with emission and reception of the optical signal; correcting the time according to a plurality of phase shift signals generated based on the reference signal; and minimizing an error of the time by increasing the quantity of the phase shift signals. The method enhances the accuracy of the measured time taken by an optical signal to travel to an object and return therefrom, speeds up measurement, and reduces the required circuit areas. A system for measuring distance is further introduced for use with the method.
Abstract:
A method for parking a mobile communication apparatus of a femtocell base station and applicable to a communication network including a core of an apparatus network, the femtocell base station, and the mobile communication apparatus. The femtocell base station obtains a RRC connection request of an international mobile station identity (IMSI) of the mobile communication apparatus and compares the obtained IMSI with the IMSIs in a mobile communication apparatus authority list created in the femtocell base station. Once the mobile communication apparatus enters a communication area covered by the femtocell base station, the femtocell base station will determine whether the mobile communication apparatus is authorized to park the communication area or not . Unauthorized subscribers are rejected before the femtocell base station is established the communication relation with the core of the apparatus network, thereby saving network resource and speeding up rejection.
