A method, terminal device, network element, system and computer program product for controlling discontinuous reception or transmission at a terminal device of a communication network are disclosed. A regular discontinuous reception or transmission cycle of a regular discontinuous reception or transmission scheme is set by using a first control layer, and in addition thereto a shorter temporary discontinuous reception or transmission cycle of an interim discontinuous reception or transmission scheme can be set by using a second control layer. This arrangement provides long discontinuous reception or transmission cycles for power consumption improvements while at the same time ensuring that the network can easily and flexibly shorten these cycles for increased data throughput, if needed.

A new network-adapted type protocol conversion connector with a function for converting the protocol for control signals sent and received between an indoor high-functional network laid in office buildings or dwelling houses and low-functional network-adapted appliances such as household electric appliance and facility, and an indoor communication network system using the connector. In the preferred embodiment, the protocol conversion connector comprises a primary connecting portion to be connected to the communication network laid indoors, a secondary connecting portion to be connected to a network-adapted appliance, a protocol conversion interface to convert the protocol for control signals sent and received between the communication network and the network-adapted appliance, and a feeder connecting portion to feed electric power to the network-adapted appliance to be connected to the secondary connecting portion. More improved and extended connectors designed for use in power line carrier system or wireless communication system are also disclosed as preferred its embodiments.

The printer includes a CPU, a bridge image processing unit, a RAM, a ROM, a supply power control unit, a printing unit, a communication I / F, and physical layer I / Fs. When the Ethernet is connected to the communication I / F, if the DMA transfer request signal is not outputted from the DMAC for more than a specific time, the supply power control unit shifts into the sleep mode that halts the supplies of clock to the CPU, etc.; and if data is received from the host computer group, the supply power control unit releases the sleep mode. Further, in case that equipment conforming to the USB standard or the IEEE 1284 is connected to the communication I / F, if the DMA transfer request signal is not outputted from the DMAC for more than the specific time, the supply power control unit shifts into the power halt mode that halts the supply of power to the CPU, etc. Thus, the invention provides a printer capable of effectively reducing the power consumption.

The invention discloses an oil water gas three-phase energy-saving minimal quantity lubrication system which comprises a minimal quantity oil injection device, a water solution injection device and a nozzle device. Minimal quantity lubricating oil is contained in the minimal quantity oil injection device, and water solutions are contained in the water solution injection device. Compressed air is introduced into the oil water gas three-phase energy-saving minimal quantity lubrication system and is divided into two paths, one path reaches the water solution injection device, the other path of the compressed air is divided into two branches, one branch passes the oil injection device, and the other branch is communicated with the nozzle device through a pipeline. The minimal quantity oil injection device and the water solution injection device are communicated with the nozzle device through pipelines. Flow of oil, gas and water is controlled, so that the problems that in the prior art, the water and the oil can not be evenly mixed, and the liquid outlet effect is not good are solved, and electricity use amount of an air compressor can be saved by 70-90%. Compared with a traditional lubricating technology, the oil water gas three-phase energy-saving minimal quantity lubrication system can reduce the use quantity of lubricants by more than 95% and reduce emission amount by more than 95%, and the energy conservation, emission reduction and environment protection effects are remarkable.

The second data lines are alternately arranged with the first data lines. Each of the pixel columns includes multiple first pixels and multiple second pixels. The first pixels of each of the pixel columns are coupled to one of the first data lines, and the second pixels of each of the pixel columns are coupled to one of the second data lines. The first charge sharing switch circuit each is electrically coupled to at least a part of the first data lines. The second charge sharing switch circuit each is electrically coupled to at least a part of the second data lines. A display device driving method and a source driving circuit also are provided.

In a system configured by connecting a printer (2) and a host device (3) to a line concentrator (1), an arrangement is made such that the printer (2) is held in power save mode for a for a long time to achieve power savings. When transferring to the power save mode, the printer (2) transmits internal information to the line concentrator (1). The line concentrator (1) stores this internal information in association with the printer (2). When an inquiry about the internal information is made from the host device (3) to the printer (2), the line concentrator (1) does not transmit this inquiry to the printer (2) but returns a response (proxy response) to the host device (3) by using the internal information stored in the line concentrator (1) itself. This makes it unnecessary to cancel the power save mode of the printer (2) as a result of the inquiry.

The invention provides a discontinuously-received parameter configuration method and a data transmitting method and device. The configuration method includes the steps of receiving service information transmitted by a terminal device, wherein the service information comprises a service heartbeat period, adjusting DRX parameters according to the service heartbeat period, and transmitting the adjusted DRX parameters to the terminal device to enable the terminal device to conduct DRX configuration again according to the adjusted DRX parameters to transmit service heartbeat information within DRX activation time. According to the technical scheme, influences on the power saving effect when up-link data are transmitted are reduced.

The invention discloses a control information transmission method and device. The control information transmission method comprises the steps that a first station sends a wireless signal containing control information, wherein the control information is used for notifying the designated second station in a dormant state to perform one or more operations as follows: state updating, sleep mode switching, releasing of the dormant state and operation after releasing of the dormant state; an auxiliary module of the second station receives and decodes an awakening signal and sends the decoded control information and the identity identification information to a control module; the control module of the second station judges whether the second station is a target second station of the awakening signal according to the identity identification information, and analyzes and completes the operations indicated in the control information.
