A controlling method and a controlling system for saving energy of a building are provided. In the present method, a user environment requirement is obtained first. Then, a plurality of cover ratios of a sunshade device on an opening of a building is defined, and according to an environment parameter and the user environment requirement, a total electricity consumption required by air conditioning equipment and by lighting equipment in the building corresponding to each of the cover ratios is calculated. Finally, a cover ratio that produces the minimum total electricity consumption is obtained, and the sunshade device, the air conditioning equipment and the lighting equipment are adjusted according to the obtained cover ratio, so as to make the building meet the user environment requirement and maintain a status of the minimum total energy consumption.

An electricity feature identification device and a method thereof are provided. The device comprises a receiver, a storage, and a processor. The receiver is configured to receive an electricity signal continually. The processor is electrically connected to the storage and the receiver, and configured to sample the electricity signal to obtain a piece of testing electricity information, and store the testing electricity information in the storage. The processor is also configured to sample the electricity signal every sampling interval to individually obtain a piece of reference electricity information until the number of the reference electricity information is equal to a preset sample amount, and store the reference electricity information in the storage. Finally, the processor is configured to compute a statistical feature of the reference electricity information, and compare the testing electricity information with the statistical feature to obtain a comparison result.

The present invention provides a method for realizing network topology discovery, which relates to a dynamic host configuration protocol (DHCP) client, a plurality of intermediate devices and a DHCP server and comprises: the intermediate devices recording successively address information of the intermediate devices into a DHCP option of a message in a DHCP message request sent by the DHCP client when receiving the message; and when receiving the message, the DHCP server storing a physical address of the DHCP client and information in the DHCP option carried in the message, while assigning an IP address to the DHCP client. The present invention is simple to implement, and can be implemented using only each sub-option in the original Option82 of the DHCP conveniently without additional devices, therefore it is suitable for network topology discovery of the LAN, and has high system performance-price ratio.

The present invention relates generally to nucleobase polymer functionalizing reagents, to mobility-modified sequence-specific nucleobase polymers, to compositions comprising a plurality of mobility-modified sequence-specific nucleobase polymers, and to the use of such polymers and compositions in a variety of assays, such as, for example, for the detection of a plurality of selected nucleotide sequences within one or more target nucleic acids. The mobility-modifying polymers of the present invention include phosphoramidite reagents which can be joined to other mobility-modifying monomers and to sequence-specific oligonucleobase polymers via uncharged phosphate triester linkages. Addition of the mobility-modifying phosphoramidite reagents of the present invention to oligonucleobase polymers results in unexpectedly large effects the mobility of those modified oligonucleobase polymers, especially upon capillary electrophoresis in non-sieving media.

An optical amplifier suitable for use in optical communication systems such as for telecommunications or cable television provides, for purposes of wavelength division multiplexed communications, the ability to amplify optical signals in both the C band, L band, and S band using conventional EDFA amplifiers. The S band, normally not amplifiable by EDFAs, here is amplified by converting the S band signal to a C band optical signal, providing optical amplification by an EDFA, then reconverting the amplified C band optical signal back to the S band in the same or a subsequent amplifier stage. The wavelength converters are, for instance, periodically poled lithium niobate devices using three-wave mixing, and employing difference frequency generation techniques.

An optical coherence tomography (OCT) image of the anterior chamber of an eye is processed to determine automatically a location in the image corresponding to Schwalbe's line. First, the method finds the location of the corneal endothelium. Then the method fits a model to the detected corneal endothelium. Then the method determines the location of Schwalbe's line based on the relationship between the detected corneal endothelium and the fitted model, such as where the detected corneal endothelium diverges most from the fitted model. The Schwalbe's line is used to obtain a numerical measure of the anterior chamber angle of the eye. The method can be used in a process for screening patients for glaucoma. In the case of patients found to be suffering from glaucoma, treatment can be performed.

摘要:
A semiconductor relay switch having two data ports receiving incoming signals and a power supply terminal receiving a power supply voltage is responsive to a power supply voltage level and an energy level of the incoming signals to open and close its conduction paths. The relay switch is open when a valid power supply level is detected and when there is no supply power on the power supply terminal but a high energy level is detected in the incoming signals. The relay switch is closed to allow conduction between the two data ports only when there is no power supply voltage on the power supply terminal and an energy level below a predetermined threshold is detected in the incoming signals. In one embodiment, the semiconductor relay switch includes a main conduction switch circuit, an energy detect circuit and a control signal generator.
