  • Publication number: 20110083091
    Abstract: A computer program for creating a computer program executable on one or more digital signal processors each having a predefined function set. The computer program includes computer code for receiving user input selecting one or more digital signal processors. The computer program also includes computer code for defining one or more audio digital signal processing graphical controls. Each graphical control has an associated interface handler. The computer program also has computer code for associating an algorithm module containing digital processor specific functionality with the one or more audio graphical controls using the interface handler and computer code for linking the one or more audio graphical controls together defining an execution path.

  • Patent number: 7827526
    Abstract: A method and computer program product for adding additional functionality to a graphical control for use in a computer program. The method requires providing a graphical control that is displayable on a display device where the graphical control has at least one associated input or one associated output. Initially, the graphical control does not have an associated function. A user can then select a function from a list of functions to associate with the graphical control. The list of functions is associated with computer code for implementing the functions on a particular digital signal processor. The computer system determines whether a new input or output needs to be added to the graphical control based upon a selected function from the list of functions. The computer system also determines if the graphical control should be stacked or repeated. A plurality of functions may be associated with a single graphical control.

  • Publication number: 20050286274
    Abstract: A power supply apparatus, such as an on-line UPS, includes an AC/DC converter circuit having an input configured to be coupled to an AC source, a DC/AC converter circuit having an input coupled to an output of the AC/DC converter circuit by a DC link, and a bypass circuit operative to couple and decouple the output of the DC/AC converter circuit to and from the input of the AC/DC converter circuit. Power is transferred from the output of DC/AC converter circuit via the bypass circuit to conduct a test of the apparatus, such as a factory or field load test. For example, power may be circulated around a loop including the AC/DC converter circuit, the DC/AC converter circuit and the bypass circuit to conduct the test in order to test these components under load. A status of such components may be determined responsive to the test. In further embodiments, such components may be calibrated responsive to the test.

  • Publication number: 20050265059
    Abstract: A power conversion module includes a frame, first external connection terminals supported by the frame, and at least four half-bridge circuits supported by the frame and electrically coupled between selected pairs of the first external connection terminals. The module further includes respective second external connection terminals supported by the frame and electrically coupled to respective center nodes of respective ones of the at least four half-bridge circuits. The module may also include at least four inductors supported by the frame, respective ones of the at least four inductors coupling respective ones of the center nodes of the at least four half-bridge circuits to respective ones of the second external connection terminals. The module may further include at least one storage capacitor supported by the frame and electrically coupled between a pair of the first external connection terminals.

  • Publication number: 20050262451
    Abstract: A computer program product and method for changing the value of a parameter within a computer program is disclosed. The computer program provides a single graphical control for user selection and adjustment of a plurality of parameters wherein each parameter is controlled based upon movement of a user input device. At least one of the parameters is adjusted using a non-linear equation. When the user input device is moved within a first region from a defined reference point, the parameter value is not incremented. When the user input device enters a second region the parameter value is incremented at a first rate. As the user input device is moved into a third region the parameter value is incremented at a second rate that is greater than the first rate.

  • Publication number: 20050201127
    Abstract: An uninterruptible power supply apparatus includes a first bidirectional power converter circuit having first and second ports and a second bidirectional power converter circuit having first and second ports. The apparatus further includes a DC link that couples the second port of the first bidirectional power converter circuit to the first port of the second bidirectional power converter circuit. A first load port is coupled to the second port of the second bidirectional power converter circuit and a second load port is coupled to the first port of the first bidirectional power converter circuit. The apparatus further includes a control circuit that is configured to control the first and second bidirectional power converter circuits such that each of the first and second bidirectional power converter circuits can generate and/or condition AC power at each of the first and second load ports.

  • Publication number: 20040268300
    Abstract: A computer program product and method for using a computer program product for graphically developing a computer program for execution at least in part on a separate host processor device, such as, a digital signal processor. The computer program product includes code for providing a graphical programming environment. The computer code which is used for developing the computer program includes a cell module for graphically representing a graphical control. The cell module does not contain any host processor specific code. The cell module may include code for rendering on the display of the computer that is operating as the programming environment one or more graphical controls. The cell module may also contain host processor independent code that accepts input from a user (parameter value) and converts the parameter value or applies an equation to the parameter value.

  • Publication number: 20040264704
    Abstract: A system for determining speaker spatialization parameters. The system includes a graphical interface allowing a user to select a number of listeners, number of speakers, and a listening space and for graphically displaying on a display device the one or more listeners and one or more speakers within the listening space. The system further includes a speaker spatialization module for determining one or more speaker spatialization parameters based upon the relative positions on the display device of the one or more listeners and the one or more speakers within the listening space system. The user may reposition the speakers and for each speaker that is repositioned the speaker spatialization module recalculates the speaker spatialization parameters for that speaker. The user may also graphically reposition one of the listeners and the speaker spatialization module recalculates all of the speaker spatialization parameters for all of the speakers.
