A wireless base station, relates to the field of communications technologies, and is designed to implement more precise adjustment and control of a device, and to enable the device to have a compact form and high integrity. The wireless base station includes a supporting module and a base station module. The wireless base station further includes a first connecting part. The base station module is slidably disposed on the supporting module in a first sliding direction using the first connecting part, where a first sliding slot matching the first connecting part is disposed on the supporting module, so as to limit a sliding track and a sliding range of the base station module, and the first sliding slot is in an arc shape. The present disclosure may be used for manufacturing a communications device.

The present invention discloses a cable positioning apparatus, including a base, a snap-fitting apparatus, and a cable clamp. The base includes a front side, a rear side opposite to the front side, and an end face connecting the front side and the rear side. The snap-fitting apparatus is arranged on the rear side of the base, and the snap-fitting apparatus includes a lock, where the lock is configured to retract to insert into a corresponding installation hole when external force is applied, and restore, when the external force is removed, to an initial position to be locked into the installation hole. Using the apparatuses according to the present invention, a cable is limited without using any other tool, thereby greatly reducing the time spent laying out and positioning a high density of cables.

This invention is suitable for use in the field of integrated circuits. It provides a type of power source circuit. Said power source circuit includes: a charge pump circuit used to operate the charge pump to produce driving voltages; a first control circuit, used in the closed-loop control of said charge pump circuit to produce a positive high voltage; a bias-ratio circuit, used with the positive high voltage and the zero-potential voltage produced by the first control circuit to produce a positive sub-high voltage and a lowest positive high voltage; and a second control circuit, used in accordance with the positive sub-high voltage and the lowest positive high voltage produced by said bias-ratio circuit in the closed-loop control of said charge pump circuit to produce a negative high voltage. Using this invention, the system contains no voltage higher than the liquid crystal's driving voltages, and also does not contain any lower negative voltage than the liquid crystal's highest negative driving voltage, thereby reducing the circuit's electrical consumption.

This invention describes methods and circuits for the segment driver circuit in a LCD driver system as well as application specific SEG decoder. The methods include the following steps: the array signal undergoes an inversion process (from 1 to 0, or from 0 to 1); the data and the array signal that has been processed through the inversion process then undergo a matrix operation; the signal that has gone through the matrix operation is then sent to a BBM (break before make) circuit. The signal processor of the application specific SEG decoder performs the inverse operation (from 1 to 0, or from 0 to 1) on the array signal; the decoding circuit performs the matrix operation on the signal that has been inversed (from 1 to 0, or from 0 to 1) before sending it to the BBM circuit. The methods described in this invention first process the array signal through field processing and inverse processing (from 1 to 0, or from 0 to 1) before undergoing the matrix operation, rather than first performing the matrix operation and then selecting an output based on the field signal. Therefore, this invention enhances the SEG decoder by simplifying the circuitry, reducing energy consumption, lowering cost, and making it easier to realize.
