A computer-implemented method may include determining whether a computing device accessing an online application marketplace is associated with a particular business entity registered with the online application marketplace. The method may further include identifying applications that were selected by a representative of the particular business entity to be identified to users whose devices are determined to be associated with the particular business entity. The method may still further include providing data for displaying the applications and a control for downloading executable code for at least one of the applications, receiving an indication that the control has been selected by the user to download the executable code for the applications, and providing the executable code for the at least one of the applications.

Mobile application management

A method may include sending, by a client device, an access request to an authentication server device. The access request may include a request to access an administered resource. The method may include in response to the client device not complying with an administrative policy associated with the administered resource, receiving, from the authentication server device, one or more instructions regarding installation of a client application, receiving, by the client device, a client application in accordance with the instructions, and installing the client application on the client device.

Policy enforcement of client devices

Systems and techniques are disclosed for providing a standard version of an application to a first user, receiving a request for the application from a second user, identifying the second user as a test user, and providing a second version of the application to the second user based on the identification. Interaction events with the second version of the application, by the second user, may be reported and used by the arrangement to modify the second version of the application. Alternatively, a second user may reject the second version of the application and the second user's status may be modified based on the rejection.

A controller circuit for the control of a power converter is disclosed. An example controller circuit generates a waveform that drives a switch that controls the power converter. The controller circuit includes a divider module that generates a modification factor based on a ratio of the two input signals of the module. The circuit includes a module that generates a first waveform configured for a critical conducting mode of operation of a power converter and an on-time adjuster module that modifies the first waveform based on the modification factor and generates a second waveform. The second waveform is delivered to the switch. An example modification factor is the ratio of the output voltage to the rectified input voltage of the power converter.

Low total harmonic distortion and high power factor correction power converters

A fault protection and correction circuit for the control of a power converter is disclosed. An example circuit generates a waveform that drives a switch on or off and controls the power converter. The controller circuit in addition to power factor correction (PFC) circuitry includes a first and a second shut down mode modules, both of them cause the switching to stop. The circuit includes a module for receiving fault events. When a fault occurs, the controller enters the second shut down mode. The controller stays in the second shut down mode if the required current for this mode can be provided by the outside circuitry. Otherwise, the controller enters the first shut down mode that requires less current and subsequently restarts the controller. By modifying the outside circuitry the controller can respond differently to fault events.

Fault protection and correction of line and load faults

In one example, a device executes one or more video communication processes that receive audio streams and video streams from a plurality of computing devices participating in a video communication session associated with the one or more video communication processes. The device evaluates one or more properties of the audio streams, including the volume of an audio signal among the audio streams. The device selects a first group of the audio streams to mute in the video communication session, based at least in part on the one or more properties of the audio streams. The device distributes a second group of the audio streams in the video communication session, while muting the first group of audio streams in the video communication session.

Automatic mute control for video conferencing

A dual-mode circuit for the control of an AC/DC power converter is disclosed. An example dual-mode controller circuit generates a waveform that drives a switch on or off and controls the power converter. The controller circuit in addition to power factor correction (PFC) circuitry includes a critical conducting mode (CrM) module as well as a discontinuous conducting mode (DCM) module configured to generate waveforms adapted for CrM and DCM operation of a power converter. The circuit includes a node for receiving a feedback signal of a voltage or a current. Based on the received signal, one of the modules is selected at a time to supply the waveform at the output of the dual-mode controller. An example of the output waveform is a series of pulses that are configured to drive the switch that controls the transfer of power between input and output of the power converter.

Dual-mode, AC/DC power converter with power factor correction

The present invention provides an improved method and apparatus to measure p-n junction device temperature by testing a device with M-Levels of applied collector current, sensing changes in output characteristics, and calculating the device current offset error and leakage current error due to parasitic parallel resistance where the leakage current error due to parasitic parallel resistance may be treated and eliminated as current offset error. Application of M levels of excitation values, where M is greater than or equal to four, eliminates device series parasitic effects, comprised of voltage offset and a series parasitic resistance, and parallel parasitic effects, comprised of current offset error and leakage current error due to parasitic parallel resistance, from temperature measurements. Since the operating characteristics of the device are temperature dependent, excitation levels applied and output values observed are used to determine junction temperature of the device free of series and parallel parasitic effects.
