  • Publication number: 20250004343
    Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.

  • Patent number: 12169872
    Abstract: Systems and methods for determining how to dispatch power to a property from a generator are provided. According to certain aspects, a controller associated with the generator may retrieve or access a set of data indicating time of use rates associated with utility power, performance characteristics of the generator, and/or energy usage data. Based on the data, the controller may determine a set point corresponding to when it may be beneficial to dispatch generator power to the property instead of utility power. At the set point, the controller may facilitate supplementing power from utility power with power from the generator. Additionally, the controller may collect usage and performance data associated with dispatch of the generator power.

  • Publication number: 20240084907
    Abstract: An enhanced low noise relief valve renders the anodizing processing irrelevant to the low leakage nature of the valve member based on the tolerance between the tube portion of the valve member and the inlet bore of the machined housing. This is accomplished by providing an additional valve stem holder that acts as a stem holder through which at least part of the tube portion of the valve member extends, with the stem holder instead of the valve member tube being located adjacent to the bore of the machined housing. The stem holder does not need to be subject to the anodizing process, and therefore a tight tolerance between the valve member and stem holder provides adequate leakage control, and the anodizing process applied to the machined housing otherwise is separated from the location where leakage tolerance is critical.
