A method and system for proactively dropping video frames are disclosed. The method includes: recording, by a computer, a video frame capture timestamp for a video frame that is captured at a first device; associating, by the computer, the video frame capture timestamp to the video frame that is captured; comparing, by the computer, the video frame capture timestamp with a video frame target timestamp for the video frame; and based on the comparing, if a time difference between the video frame capture timestamp and the video frame target timestamp is outside of a predetermined range of time values, then dropping, by the computer, the video frame.

An adapting circuit is connected onto the high voltage end output of a magnetron driving power supply. In the adapting circuit, the high frequency part of current in the magnetron anode loop is converted into a part of the filament driving current. The high frequency part is removed by the two primary coils of a ferret core transformer and converted into a larger current on the secondary coil, which is rectified and filtered to increase the driving current in the magnetron filament loop. Two or more power supplies connected with the adapting circuits are connected together in parallel to drive a high power and high filament driving current magnetron with a correct compensation for its filament current.

A power supply for use in a UV curing lamp assembly is disclosed. The power supply is powered by two intermediate frequency (200-400 Hz) low voltage sinusoidal power sources that drive the primary windings of a dual laminated transformer. The low voltage sinusoidal power sources are configured to have different phases. The out-of-phase low voltage sine wave sources are converted to high voltage sine waves on the secondary windings of the dual laminated transformer having the same phase difference relationship. A single rectifier comprising six high voltage diodes, called a ladder rectifier, combine the two out-of-phase sine waves into a single, approximately DC output power source. By modulating a phase difference between two input sine wave power sources, the approximate DC output voltage exiting the ladder rectifier may be alternated between a low ripple mode of about a 13.84% ripple, a high current mode, a high voltage mode, and an intermediate mode with a ripple in the range of about 13.84% to about 100%.

A system for enabling communication between devices is described. The system includes the following: a media processing information receiver configured for receiving, at a first device, media processing information associated with a second device, wherein at least one of the first and second device is a mobile device; a comparer configured for comparing the media processing information to a processing time of the at least one media processing component of the first device; a target adjustment level determiner configured for determining a target adjustment level, wherein arriving at the target adjustment level enables the first and second device to achieve a matching media processing quality level; and a media processing component adjuster coupled with the computer and configured for adjusting the at least one media processing component of the first device to meet the target adjustment level.
摘要:
A method for utilizing an instrumented application in a mobile device environment. The method includes instrumenting an application to generate an instrumented application configured for use in the mobile device environment, obtaining authorization from a governing body for use of the instrumented application in the mobile device environment, and directing the instrumented application to cause a mobile device to operate according to a first setting. The first setting is invoked without requiring further authorization by the governing body.
