  • Publication number: 20170047729
    Abstract: A relay protection method against LC parallel circuit detuning faults comprises the steps of: a relay protection device samples a current of a parallel LC, that is, a reactor and a capacitor, and samples a total current flowing through the whole LC; convert the current of the reactor into a current of an equivalent capacitor; calculate amplitudes of the current of the equivalent capacitor and a current of a realistic capacitor and calculate an amplitude of the total current flowing through the LC; calculate a current amplitude ratio of the equivalent capacitor to the realistic capacitor; and when the amplitude of the total current flowing through the LC is large enough, send an alarm signal or a trip after a setting time delay if the current ratio exceeds a preset upper and lower limit range. Also provided is a corresponding relay protection device.

  • Patent number: 9288657
    Abstract: A separate domain selection function is utilized as the first function in a communication path for a communication that is to be connected to a user device registered in a first network or a second network. If a result of the domain selection function indicates call control should be maintained by first network (e.g., user device is registered with first network or a network with which first network has a control relationship), call control of the communication remains with first network. If the result of the domain selection function indicates the user device is registered with second network, call control is suspended by the first network, which allows the communication to bypass the first network.

  • Patent number: 8336135
    Abstract: A joining device is provided for rails of a baby bed, in which the joining connects two adjacent rail tubes of the rail, where an end of each of the rail tubes is pivotally connected to the joining device. The joining device is formed as a saddle part in a shape having two upstanding side walls and an arched portion connected between top edges of the two side walls. The joining device further has a smooth contact face formed on each of the two sides of the arched portion and a smoothly trimmed face connected to the smooth contact face, so that the tube walls of the rail tubes are contacted with the smooth contact faces when the rail tubes are pivotally rotated close to the two sides of the arched portion.

  • Patent number: 7956032
    Abstract: The present invention provides conjugates between Granulocyte Colony Stimulating Factor and PEG moieties. The conjugates are linked via an intact glycosyl linking group that is interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from both glycosylated and unglycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar moiety onto either an amino acid or glycosyl residue on the peptide. Also provided are pharmaceutical formulations including the conjugates. Methods for preparing the conjugates are also within the scope of the invention.
