  • Publication number: 20120227028
    Abstract: Automatically generated user interfaces are provided to aid data population of object instances in graphical programming environments. A selection gesture identifies an instance of an object type. The public fields defined for the instance are automatically determined, and a user interface is automatically generated with the name of each defined field and a currently assigned value for each field that has one. Fields which have no currently assigned value are optionally displayed with a hint. The user interface can be placed in an application under development, such as a sequential workflow application, as a class initializer and/or as an object configurator. When the object to be populated has another object as a field, the fields of that nested object are similarly displayed. Data can be entered into a container object through the user interface without replacing prior value(s) of the container object.

  • Publication number: 20120133374
    Abstract: A method for detecting a capacitor loss is applicable to detecting a plurality of by-pass capacitors connected in parallel to each other. The detection method includes the following steps, an alternating current (AC) signal is input into the by-pass capacitors, in which the AC signal has a plurality of test frequencies; test voltages of the by-pass capacitors at each of the test frequencies are recorded, so as to form a test result table; it is determined whether the test result table is the same as a standard voltage table; and when a result of the determination is NO, a fail signal is output. By applying the detection method, whether a loss exists in the by-pass capacitors can be effectively identified, thereby solving the problem that small capacitors are undetectable when large capacitors are connected in parallel to the small capacitors.

  • Publication number: 20110194431
    Abstract: In the context of IEEE 802.11 WLAN networks, enhancement to the Relaxed Deterministic Backoff (R-DEB) for random access of shared (Medium Access Control MAC) method. For all available candidate resource slots, a busy index is calculated that reflects the level of use/occupation in the past and infers a probability of use in the future by another concurring device. The method assumes the use of a sub-set of resource slots for transmission, and updates this set by replacing resource slots for which collisions are frequent with a not currently used candidate resource for which the busy index is the lowest. Passive Spoofing/overhearing of all resources for clear channel assessment (CCS) is used for resource monitoring purposes.
