    Abstract: A family of emitter turn-off thyristors and their drive circuit comprise a gate turn-on (GTO) thyristor, a first switch, the drain of the first switch being connected to the cathode of the GTO thyristor, and a second switch connected between the gate of the GTO thyristor and the source of the first switch. The first switch consists of many paralleled metal oxide semiconductor field effect transistors (MOSFETs). The anode of the GTO thyristor and the source of the first switch serve as the annode and the cathode, respective, of the emitter turn-off thyristor. The emitter turn-off thyristor has four control electrodes: the gate of the GTO thyristor, the control electrode of the second switch, the gate of the first switch, and the cathode of the GTO thyristor. The drive circuit comprises a current source circuit, a voltage clamp circuit, a current direction detector, and a control circuit. The ETO thyristor further comprises a current sensing and over-current detector circuit. The first switch is packaged in a printed circuit board.

    Abstract: A computer implemented method for clustering customers includes receiving a source set of customer records, wherein each customer record represents one customer, and each customer record includes at least one data attribute, and each data attribute has an attribute value; pre-processing the source set of customer records to generate a pre-processed set of customer records; executing a clustering algorithm on the pre-processed set of customer records to group the pre-processed set of customer records into clusters of a pre-defined number. The pre-processing comprises: determining the type of a customer in the source set of customer records; using a type attribute value to indicate the type of the customer in its customer record; normalizing data attribute values and type attribute values; weighting to the data attribute values and the type attribute values respectively to obtain weighted attribute values of the data attribute and weighted attribute values of the tune attribute.

    Abstract: A method for storing information items from a client device to a remote server is performed at the client device having memory and one or more processors, the remote server being communicatively coupled to the client device. The client device renders an information item and an information storing option associated with the information item using a first application at the client device. Upon detecting a user selection of the information storing option, the client device invokes a second application, which may or may not run on the client device, to upload data associated with the information item rendered on the client device to the remote server and then resumes the rendition of the information item using the first application at the client device.

    Abstract: A nested chain of densest subgraphs is derived by a computer from a given graph that has multiple vertices and edges. The two ends of each edge are assigned with respective incident weights, and each vertex is given a vertex weight. A weight balancing process is carried out by the computer to iteratively go through the edges to adjust the incident weights of each edge and the vertex weights of the vertices connected by that edge to reduce a difference between the vertex weights of the two vertices. After the balancing, the vertex weights are put in an ordered sequence according to their values, and a nested chain of densest subgraphs is derived from the ordered sequence.

    Abstract: Systems for leveling UV-curable gel ink include a leveling member having a conformable surface. The leveling member is a quartz tube rotatable about a longitudinal axis, and connected to a mandrel, with conformable VITON O-rings interposing the mandrel and the quartz tube. A UV source is disposed within the quartz tube, and configured to emit light through the quartz tube and the conformable surface onto a surface of a substrate passing through a leveling or pressure nip defined by the quartz tube and a backing member or pressure belt.
