A modem includes a temperature detecting module, a frequency detecting module, and a power offset calculating module. The temperature detecting module detects a real-time-work temperature of the modem. The frequency detecting module obtains a real-time-work frequency of the modem. The power offset calculating module calculates a power offset by inputting the real-time-work temperature and the real-time-work frequency into a pre-stored calculating model and adjusts a power of the modem according to the calculated power offset. A method of adjusting power of the modem is also provided.

A method for establishing a new network connection using a router includes receiving notification of switching network modes of the router, and detecting whether a new network connection is established by the router. When the new network connection is disabled, the clients are disconnect from a LAN port of the router, a recertification request from the clients is refused, and the recertification request after a first predetermined time duration is received. Thus, a network connection is established.

A telephone network access device switchable between a VOIP service and a PSTN service includes an RJ-11 port, a voice splitter, a first relay, a second relay, a SLIC chip, a CPU, and a ring detection unit. The ring detection unit outputs a first switch signal in response to detecting a ring signal of a PSTN communication. The second relay connects the telephone to the VOIP network in response to a power on event. The CPU controls the first relay and the second relay to connect the telephone to the PSTN network in response to the CPU receiving the first switch signal, and controls the second relay to reconnect the telephone to the VOIP network when the PSTN communication ends.

A product outer shell containing its own record of any private and unwarranted disassembly includes a first outer element, a second outer element detachably connected with the second outer element, a consumer disassembly inhibiting structure. The consumer disassembly inhibiting structure includes a circuit board, a plurality of special conductive bodies, a plurality of general conductive bodies, and a positioning plate. The special conductive bodies and general conductive bodies all have the same structures and each is secured on the circuit board to electrically connect to a chip located on the circuit board. A conductive piece is positioned on the positioning plate and is coupled with the special conductive bodies. The chip is configured to record electric connections between the special conductive bodies and the conductive piece, the original electric connections being changed to other or no connections after any disassembly of the product outer shell.

A waterproof cap for electronic devices includes a cover plate and sealing base located on a surface of the cover plate for sealing a port of a housing of the electronic devices. A first lip and a second lip are located on an outer periphery of the sealing base and are spaced apart from each other. The first lip is located between the cover plate and the second lip. When the sealing base is inserted into the port of the housing of the electronic devices, the first lip is configured to tilt toward the cover plate, and the second lip is configured to tilt away from the cover plate.
摘要:
A method for transferring an incoming call from a first communication device to a second communication device inquires as to a preselected process mode. The process mode can include a call answering mode, a call rejection mode, and a call transferring mode. Under the call transferring mode, the first communication device acquires contact numbers of the second communication device through a short distance communication unit. Then the first communication device sends the acquired contact numbers or a transfer command included the acquired information to a server and the server transfers the incoming call from the first communication device to the second communication device.

摘要:
An electronic device includes a case and a connector. The case includes a first sidewall, a second sidewall perpendicularly connected to the first sidewall, and a pair of latching protrusions. A through hole is defined in the first sidewall. The pair of latching protrusions is located on the two opposite sides of the through hole and perpendicular extended from the second sidewall. Each of the latching protrusions comprises a first side near to the through hole and a second side away from the through hole. The connector is inserted in the case. The connector includes a shaft portion and a flange radially extending from the shaft portion. The shaft portion is inserted into the through hole. Thus, securing the connector from falling.
