The invention relates to the technical field of illumination, and discloses an adjustable solar street lamp with an LED lamp. The adjustable solar street lamp comprises a base, a street lamp pipe is fixedly installed on the top of the base, a sliding groove is formed in the left side of the street lamp pipe, a strip-shaped opening is formed in the right side of the street lamp pipe, a rotating rod which is rotatably connected with the street lamp pipe is horizontally arranged at each end of the interior of the street lamp pipe in a penetrating manner, and square blocks are fixedly installed on the reverse side and the obverse side of the bottom rotating rod respectively. According to the adjustable solar street lamp with the LED lamp, the street lamp achieves a free vertical adjusting function through gears and a chain; when the street lamp needs to be maintained, the street lamp can be maintained or an LED lamp holder can be replaced only by putting a displacement block at the lowest end, a maintenance vehicle does not need to be used, the maintenance work can be completed through one person and one Z-shaped hand cranking rod, manpower and material resources are saved, therefore, the solar street lamp achieves an adjusting function, and the manpower and material resources which are needed for maintaining the solar street lamp are reduced.

The present invention discloses a displacement detecting device including a displacement sensing module, an input module, a distance sensing module, and a processing module, and a power saving method thereof. The processing module is electrically connected to each module. The input module is used to supply non-contact operation. The distance sensing module is used to detect the distance between a body and the displacement detecting device, and then produces a sensing value. The processing module selectively control the displacement sensing module and the input module to be turned on or turned off according to the sensing result of the distance sensing module. The displacement detecting device turns on the displacement sensing module when the sensing value is less than a first default value, and turns on the input module and turns off the displacement sensing module when the sensing value is greater than a second default value.

The invention discloses a computer peripheral device. The computer peripheral device comprises a USB (Universal Serial Bus) concentrator, built-in card readers and a controller, wherein each built-in card reader is in telecommunication connection with a built-in downstream end USB port of the USB concentrator, and the controller is in telecommunication connections with the USB concentrator and the built-in card readers and controls the same so as to monitor whether the built-in card-readers are needed to be kept in connection. When the controller judges that one of the built-in card readers is not needed to be kept in connection, the controller sets the built-in downstream end USB port corresponding to the built-in card reader to be in a first state, so that the built-in downstream end USB port can be considered as not being used. So that a computer host can be informed with that the built-in downstream end USB port is not used, then, the computer peripheral deice can enter into a sleep mode when other downstream end USB ports are not connected with any other USB devices, so as to save energy and electricity.

The invention discloses a state control method and apparatus of a set-top box and a set-top box. The method comprises: whether existence of a human body is detected in a predetermined distance range is determined; and if not, a set-top box is controlled to enter a standby state. Therefore, a problem that resources are wasted because a state of a set-top box can not be controlled timely in the correlated technology can be solved; and thus effects of energy conservation and power saving can be realized.

The first dynamic thermal information and the second dynamic thermal information can be received by the controller, the variable-frequency pump can be dynamically operated under the control of the controller according to the first dynamic thermal information and the seconddynamic thermal information, or flow can be dynamically adjusted by the first electric valve and the second electric valve under the control of the controller according to the first dynamic thermal information and the second dynamic thermal information.

The present invention discloses a master-slave type intelligent extension socket, which mainly comprises a master extension socket and a slave extension socket. Technically, a user can remotely control the energized state of each socket jack of the master extension socket by an intelligent mobile device. Meanwhile, the master extension socket is enabled to control the energized state of each socket jack of the slave extension socket through short-range wireless signals. As a result, the user can further control the energized state of the slave extension socket connected with the master extension socket through remotely controlling the master extension socket. In this way, the effect that the user can simultaneously control a plurality of intelligent extension sockets without the need of purchasing the plurality of extension sockets having the remote connection function can be realized, so that the waste of associated resources is avoided. In addition, under the architecture of the master-slave type intelligent extension socket, an intelligent mobile socket can be further added for common use. Likewise, based on the short-range wireless connection of the master extension socket with the intelligent mobile socket, the function of remotely controlling the intelligent mobile socket by the user through the master extension socket can be realized.
