Abstract:
A switch-mode voltage converter has a switching transistor coupled between an input voltage (Vin) and the ground and a controller coupled directly between the input voltage (Vin) and the ground. The controller periodically turns on the switching transistor for a generally constant period of time. The controller is further coupled to a DC bias voltage (Vbias) and generates a control current based on the input voltage (Vin) and the DC bias voltage (Vbias) for generating a switching signal to the switching transistor.
Abstract:
A user behavior model provides personalized recommendations based in part on time and location, particularly to users of mobile devices. Entity types are ranked according to relevance to the user. Example entity types are restaurant, hotel, etc. The relevance may be based on reference to a large-scale database containing queries from other users. Additionally, entities within each entity type may be ranked based on relevance to the user and the time and location context. A user interface may display a ranked list of entity types, such as restaurant, hotel, etc., wherein each entity type is represented by a highest-ranked entity with the entity type. Thus, the user interface may display a highest-ranked restaurant, a highest-ranked hotel, etc. Upon user selection of one such entity type the user interface is replaced with a second user interface, for example showing a ranked hierarchy of restaurants, headed by the highest-ranked restaurant.
Abstract:
A server includes a case, a fan module, and a main board module unit. The fan module is disposed in the case and divides the case into first and second spaces. An air flow is sucked into and blown out of the fan module along a first direction. The main board module unit includes a main board module back plate and main board modules. The main board module back plate is horizontally laid in the first space. Each main board module having a hard disk is detachably inserted in the main board module back plate along a second direction, and electrically connected to the main board module back plate. Two maximum area surfaces of each main board module are parallel with the first direction. Air flow channels are formed between the main board modules extending along the first direction.
Abstract:
A method for analyzing an electrical power system using fuzzy logic includes: (a) acquiring data representing a signal of interest of the power system; (b) analyzing the signal using at least one fuzzy logic rule, wherein the fuzzy logic rules include: (1) phase level rules which are based on features extracted from a particular phase on the electric power system; (2) segment level rules which are evaluated using information from different phases; and (3) capture level rules which combine truth values obtained from one or more segments; and (c) based on the analysis, detecting and classifying at least one power system event within the power system.
Abstract:
A handle structure suitable for disposing on a surface of a carrier is provided. The carrier has a locating part is assemble to a case. The handle structure includes a holder, an elastic element and a fastening element. The holder has a rotating axis and a locating element, and has a first end and a second end opposite thereto. The rotating axis connecting to the carrier is disposed on the first end, and the holder is pivoted on the surface. The locating element disposed on the first end interferes with the locating part. The elastic element has a first fixing part fixed to the carrier and a pushing part connected to the first fixing part and pushing against the holder. The fastening element has a second fixing part fixed to the carrier and a fastening part connected to the second fixing part and fastened to the second end.
