  • Patent number: 8804385
    Abstract: A switching converter IC without a built-in power switching device includes a first terminal serving as a power supply positive connection, a second terminal serving as a power supply return connection, a third terminal serving as the switch-driving connection for controlling the switching duty of an external bipolar or MOSFET power switching device and also serving as a conduit for detection of current drawn by the power switching device to thereby provide overcurrent protection.

  • Publication number: 20140095233
    Abstract: A method of modeling a scenario for use with live data in a production database may include selecting the scenario. The live data can be stored in the production database on a first computing resource, and production scenarios can be stored and executed on the live data using the first computing resource. The method may also include identifying a subset of the live data that are affected by the scenario, copying the subset to a second computing resource to create modeling data, running the scenario on the modeling data using the second computing resource, causing a display device to provide an output comprising a result of the scenario on the modeling data, receiving an input indicating that the scenario is approved, and storing the scenario with the plurality of production scenarios for use on the first computing resource.

  • Patent number: 8645234
    Abstract: A web-service for validating or invalidating accounts from a general ledger (GL) chart of accounts is described. Upon a request from an application for whether an account value corresponding to a department and a product is valid, the service indicates whether the combination of account value/department/product is valid for the chart of accounts. The system can be extensible markup language (XML)-based and can indicate validity down to the line level of a request.

  • Publication number: 20110191213
    Abstract: A computer is programmed to receive from an administrator, a rule specifying one or more values of a parameter, identification of software wherein the rule is to be applied, and identification of a user on whom the rule is to be applied. The computer stores an association between the rule, the identified user and the identified software. On receipt of input from the identified user, to access the identified software, the computer uses the association to retrieve the rule, apply the rule to select information based on the value(s) specified in the rule, and execute the identified software to display the selected information to the identified user. Use of a rule that is specific to the user and also specific to the software enables the computer to support security for each user differently for different pieces of software in a software product line.

  • Publication number: 20110191214
    Abstract: A web service for automatically determining accounting entries that are affected by the deletion of a journal, formulating reverse accounting entries, and sending the reverse entries back to the source system is described. The service can use transaction identification keys to map and track which accounting entries are affected by the deletion of the journal. The web service can use extensible markup language (XML) among other formats.

  • Patent number: 7477051
    Abstract: A position sensor includes a first part having several electrically conductive elements, a second part having an electrical conductor, and holding device holding the first part and the second part together with the conductive elements and the conductor being spaced apart and permitting relative movement between the conductive elements and the conductor. Included is a signal generator for generating and supplying different electrical signals to one of the first part and the second part for reception in a contactless manner by the other of the first part and the second part with a magnitude that is dependent upon the relative position between the conductive elements and the conductor. There is also a signal detector connected to the other of the first part and the second part for differentiating the electrical signals received thereby to determine the relative position between the conductive elements and the conductor.

  • Patent number: 7362072
    Abstract: A method of controlling a two-phase stepping motor to operate in one of a plurality of operating modes in which output of the motor behaves differently upon encountering obstacle, comprises the steps of: generating an electrical driving current comprising a repeating series of a positive active driving region, a first inactive driving region, a negative active driving region and a second inactive driving region; determining one of the duration of the active driving regions and the duration of the inactive driving regions relative to the other of the durations to thereby cause the motor to operate in a corresponding mode of the operating modes; and applying the driving current to the motor.

  • Patent number: 5331264
    Abstract: A method and device of achieving motion cycle time reduction that takes motor capabilities, load inertia and gravity into account and, at the same time, produces acceptable tool tip vibration upon stopping. This cycle time reduction is especially applicable to short motions of a robot where the entire motion consists of acceleration and deceleration and there is no constant velocity region. The method and device provide open loop limiting factors for axis jerk, acceleration and velocity, taking into account robot position, payload and inertia.
