Voltage regulator with piecewise linear loadlines
Apparatus and associated methods relate to providing a piecewise loadline having a number of segments with different slopes and selecting a segment of the piecewise loadline based on an output current of a power supply. In an illustrative example, the piecewise loadline may include a segment that has a negative slope.

Predicting responses of resources to demand response signals and having comfortable demand responses
An approach where a utility/ISO may dispatch demand response (DR) resources in real time without notification of a DR event. DR dispatches may involve sending specific load level commands to power generators that can respond to such commands in a predictable fashion. DR resources do not necessarily have the same level of control or predictability in their load responses. Accuracy of predicting a DR resource's response to a DR signal may be improved by restricting the DR signal to predefined finite values and, for each predefined finite value, have the DR resource continuously report back what its load response will be if one of those signal values is sent as a DR signal. A DR performed against a home may result in discomfort. But there may be a sufficient recovery rate for regaining the setpoint of a thermostat to attain comfort of the home within a reasonable period of time. |

System to determine effects of vibration on weight data for a fixture
Fixtures can hold one or more items. Load cells may be used to measure the weight of the items on the fixture. In cases where items are added to or removed from the fixture, the load cells will detect a weight change at the fixture. Data reflecting the weight change is then used to determine interactions with the items on the fixture. However, vibrations to the fixture can introduce noise which can lead to inaccuracies in weight data acquired from the load cells. A vibration sensor can be used to measure the level of vibration detected at the fixture. Weight data acquired during a time interval when vibrations exceed a vibration threshold value is deemed invalid weight data. By contrast, weight data acquired when vibrations do not exceed the vibration threshold value will be deemed valid weight data that can be used for determining interactions with items at the fixture. |

High speed centrifugal pump lined seal housing
A centrifugal pump, and components thereof, operable at high speeds, is described under the present disclosure. A hard polymer sleeve can be applied to certain surfaces of a seal casing within the pump.
