Abstract: An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal. The signal can be provided intermittently and a carrier wave also provided and modulated at the same time as the signal. When the signal is not being produced, the power on the power line may be power that is allowed to flow without manipulation from an external portion of the power line.

Abstract: A novel pillow is provided to easily adjust its height by pulling one or both levers of a unique double-lever air valve. Pulling a first lever opens up a smaller opening suitable for gradual deflation of the pillow and reducing its height under a pressure of a user head laying over the pillow. Pulling both levers together activates an electrically driven air pump to rapidly inflate the pillow through a larger opening so as to increase its height.

Abstract: A plurality of nodes installed throughout a building each include a wall-mounted unit supported by an in-wall electrical box, a connection inside said in-wall electrical box between the wall-mounted unit and the building's mains-power wiring system, and a power line communications transceiver for communication with the other nodes through the mains-power wiring system. The nodes includes respective speakers, and are operable in a music playing mode in which music data is streamed over the mains-power wiring system to two or more nodes in different rooms of the building for simultaneous audio playback therein. The wall mounted unit includes a panel mounted over the in-wall electrical box and a plurality of light sources positioned to emit light from perimeter edges of the panel to provide a wall illumination effect on the wall surface surrounding the control panel and the electrical box.

Abstract: An LED lighting system is provided for connection to a variable power source providing input power, the LED lighting system having at least one power analyzing and processing circuitry connecting to the variable power source, and being configured to identify one or more characteristics of the input power, where the characteristics are selected from amplitude, frequency and pulse width of the input power, compare one or more of the characteristics of the input power to preset control criteria either in hardware or software or both to yield a comparison result, and then control the current control circuitry according to the comparison result.

Abstract: A pharmaceutical composition for the prevention, protective effect, or treatment of a neurodegenerative condition, is provided. The composition includes a combination of cannabidiol water soluble powder; astaxanthin; alpha-glyceryl phosphoryl choline; and phosphatidyl serine. Optional supporting ingredients may be provided also.

Abstract: An electrical switch device features a switch module housing that fits at least partially within an in-wall electrical box. The housing contains electrically controlled switches and has line and neutral contacts carried for each of the electrically controlled switches to enable connection of a different respective load circuit across each electrically controlled switch. A control panel is mountable over an open front of the in-wall electrical box and the housing therein, and has a user-interface for operation of the switch module to control the electrically controlled switches and connected loads. The control panel is sized to fully cover the open front of a multi-gang electrical box, whereby the same switch module and control panel are usable with either a single-gang or multi-gang electrical box without leaving any portion of the open front of the single-gang or multi-gang electrical box uncovered by said control panel.

Abstract: The present invention surrounds an apparatus and method for the use in injection molding of articles of manufacture using an injection molding apparatus having a valve-gate pin or a plurality of valve-gate pins for actuation to extend and retract from a cavity within an injection mold. The valve-gate pin may have a retention feature or retention features configured for the retention of molded parts such that the retraction or extension of the valve-gate pin provides part removal from an associated injection mold. Further, the valve-gate pin may have a feature or features to facilitate the injection of fluids, gases or particles during or after the primary injection process. Additionally, a plurality of such valve-gate pins may be employed within each mold cavity, or within each valve-gate actuation system.

Abstract: The present patent document provides embodiments of a filter and a system for use with the filter for separating dirt and other contaminates from wash liquids. In a preferred embodiment the filter comprises: a plurality of passages all oriented parallel to each other wherein the passages have a circular top with a first diameter and a circular bottom with a second smaller diameter and a portion in between the top and the bottom that is funnel shaped; a body that couples each of the plurality of passages together; wherein the passages are arranged in concentric circles radiating out from the center of the body.
