摘要:
A method for real-time capture and analysis of website performance metrics includes receiving, in each of a plurality of result servers, data values transmitted from a plurality of client devices, each data value representing a measurement of a performance metric associated with an experience of a user on a web page or using a web application, the measurement being made and the data value produced being transmitted in real-time while the user is on the web page or using the web application. For each data value received, a count in one of a set of N data buckets defined in a memory is incremented. All of the counts in each of the corresponding data buckets is aggregated to produce a histogram of the performance metric is rendered on an analytic dashboard.

A method for real-time capture of analytics from real users of a native mobile application (app) includes storing a custom metric/timer definition for a native mobile application (app) in a configuration file on a server. The custom metric/timer definition includes one or more identifiers of an element or object of the native mobile app selected by touch gesture input via a user interface on a mobile device running the native mobile app in a special mode. The configuration file is downloaded from the server to real users running the native mobile app on associated mobile devices. Immediately thereafter, one or more collector servers receive data beaconed in real-time from the associated mobile devices of the real users. The beaconed data includes custom metric/timer data obtained from the custom metric/timer definition.

An integrated circuit (IC) for controlling the discharge of a capacitor coupled across first and second input terminals of a power converter circuit, wherein the first and second terminals for receiving an ac line voltage. The IC includes a switching element coupled across the first and second input terminals and a detector circuit. The detector circuit including first and second comparators that produce first and second output signals responsive to a zero-crossing event of the ac line voltage. The first and second output signals being used to generate a reset signal coupled to a timer circuit responsive to the zero-crossing event. When the reset signal is not received within a delay time period, the timer circuit outputs a discharge signal that turns the switching element on, thereby discharging the capacitor.

An integrated circuit (IC) comprises a rectifier/regulator circuit coupled to receive an ac source voltage and output a regulated dc voltage. The rectifier/regulator circuit includes first and second switching elements that provide charging current when enabled. The first and second switching elements do not provide charging current when disabled. A sensor circuit is coupled to sense the regulated dc voltage and generate a feedback control signal coupled to the rectifier/regulator circuit that enables the first and second switching elements when the regulated do voltage is above a target voltage, and disables the first and second switching elements when the regulated do voltage is below the target voltage.

A method of operation for flyback power converter includes operating a controller of the flyback power converter in a regulation mode when a control signal is below a first threshold. The control signal is provided as an input to a terminal of the flyback power converter. When the control signal is below a second threshold and above the first threshold, the controller is operated in a limiting mode. The controller is operated in an external command mode when the control signal is below a third threshold and above the second threshold. Lastly, when the control signal is above the third threshold, the controller is operated in a protection mode.

摘要:
A semiconductor device includes a pillar formed on a substrate of the same conductivity type. The pillar has a vertical thickness that extends from a top surface down to the substrate. The pillar extends in first and second lateral directions in a loop shape. First and second dielectric regions are disposed on opposite lateral sides of the pillar, respectively. First and second conductive field plates are respectively disposed in the first and second dielectric regions. A metal layer is disposed on the top surface of the pillar, the metal layer forming a Schottky diode with respect to the pillar. When the substrate is raised to a high-voltage potential with respect to both the metal layer and the first and second field plates, the first and second field plates functioning capacitively to deplete the pillar of charge, thereby supporting the high-voltage potential along the vertical thickness of the pillar.
