Devices, methods, and systems for detecting a fault in an electrical power system which includes a source-side converter in communication with a load-side converter via a transmission line. An output current from the source-side converter to the load-side converter over the transmission line is measured during a time period from a beginning of a first current pulse of the output current to a beginning of a second current pulse of the output current. An output voltage of the source-side converter is reduced, responsive to a profile of the output current differing from an expected profile of the output current during the time period. In some implementations, the expected profile of the output current includes a current limit, and the output current differs from the expected profile by exceeding the current limit during the first current pulse.

VIDEO ALIGNMENT AND CALIBRATION FOR VIDEO QUALITY MEASUREMENT
Video alignment and calibration, which is needed for video quality measurement in full-reference mode, is performed continuously on the videos being measured to account for alignment parameters that may change over time. With this technique, the quality of video files and/or live video streams can be measured in full-reference mode in real-time. During video alignment, the temporal and spatial offsets, as well as any spatial, luminance or color transformations between the two videos are measured; during video calibration, the video frames are adjusted for these offsets and transformations so that the video quality can be measured correctly.
A waste disposal container for soiled items includes a container body, a lid over a top opening of the container body, and one or more diaphragms and a retaining ring installed inside the container body. A step feature is formed on the interior surface of the container body below the top opening. The diaphragms and the retaining ring rest on the step feature. Each diaphragm is a disk shaped member made of a flexible and resilient material such as rubber, and is partitioned into a plurality of wedge shaped sections by a plurality of radial cuts. Two or more diaphragms may be overlapped and their cuts are offset with respect to each other. The retaining ring is disposed above the diaphragms. In use, a disposable bag is placed inside the container and is held at its top between the container body and the diaphragms and the retaining ring.
A solar power system for supplying electrical energy to a load based on solar energy comprising at least one solar panel, a power supply, and at least one mode select switch. The at least one solar panel comprises at least one solar cell. The at least one mode select switch is operatively connected to the at least one solar panel, the power supply, and the load. The at least one mode select switch is operable in a first mode and in a second mode. In the first mode, the at least one solar cell is capable of supplying electrical energy to the load. In the second mode, the power supply supplies electrical energy to the at least one solar cell such that the at least one solar cell generates heat.

SIMPLIFIED MAXIMUM POWER POINT CONTROL UTILIZING THE PV ARRAY VOLTAGE AT THE MAXIMUM POWER POINT
A converter system adapted to be connected between a photovoltaic power source and a load comprises a converter circuit, a control circuit, and a PWM generator circuit. The converter circuit is operatively connected to transfer energy from the photovoltaic power source to the load. The control circuit generates a raw control signal based on at least a voltage generated by the photovoltaic power source. The PWM generator circuit is operatively connected to the converter circuit and generates a PWM switch signal based on the raw control signal. The converter circuit transfers energy from the photovoltaic power source to the load based on the PWM switch signal.

A sleeper for infants is described. The sleeper has four short legs, a frame supported by the legs and a bassinette hanging from the frame. The sleeper can rest on its legs for use in a stand-alone state, or be mounted on a playard for use as a bedside sleeper. When mounted on a playard, the sleeping surface of the sleeper has approximately the same height as an adult's bed.
