  • Patent number: 8154841
    Abstract: Assemblies, systems, and methods which prolong relay life by dynamically compensating the make and break contact timing between the contact points of the relay and a zero crossing point of the power supply's waveform are provided according to the present disclosure. The life cycle of the relay components are dramatically increased through the use of these assemblies, systems, and methods due to a decrease in arcing and other physically damaging phenomena between the contacts of the relay. The present disclosure also provides for assemblies, systems, and methods whereby a processor analyzes the inductive kickback effect in the relay load voltage signal and dynamically adjust the relay open time such that the inductive kickback effect is minimized. In exemplary embodiments, the systems/methods provided herein advantageously adjust the relay open time such that the relay switching time corresponds with current zero cross and do so without requiring complicated current monitoring components.

  • Patent number: 7755506
    Abstract: An integrated controller for complete automation with the ability to control electrical devices through both RF transmission and IR transmissions. In one illustrative embodiment, the integrated controller comprises an antenna for two-way communication with stations located throughout a structure. Each station may control the power supply to an attached electrical device. The buttons on the station may control any electrical device on the system through RF transmission with the integrated controller. The integrated controller also may comprise an IR receiver and at least one IR output. The IR receiver may receive signals from a remote and pass them through to a device, such as a device used in a home theater system, with a built in IR receiver via the IR output. In this manner, the integrated controller is capable of providing complete in home automation.
