Abstract: A power delivery sub-system included in a computer system employs a primary voltage regulator circuit that generates a primary supply voltage on a primary power supply node. The power delivery sub-system also includes multiple bypass voltage regulator circuits that source corresponding bypass currents to a local power supply nodes in an integrated circuit. The integrated circuit includes multiple circuit blocks coupled to corresponding ones of the local power supply nodes, and multiple local voltage regulator circuits coupled to the primary power supply node. When a voltage level of a given local power supply node drops below a threshold value, a corresponding local voltage regulator circuit sources a supply current to the given local power supply node.

Abstract: A system for controlling water delivery throughout a household water delivery network that includes bathroom and kitchen sinks, as well as other equipment for dispensing water, said system including a controller disposed at a site, the temperature of the water of which is to be controlled; said controller including a temperature probe for detecting the water temperature at the site; a pump for circulating water from a water heater to the site; and a wireless communication network that interconnects the controller with the pump in order to control hot water delivered from the water heater based on sensed temperature at the temperature probe. Also a process for controlling the water temperature of a water delivery system that includes a pump, either via a wifi hub or a system APP. Also disclosed is a novel adjustment ring associated with the valve.

Abstract: The present invention describes a novel outdoor enclosure for circulating pumps for outdoor tankless heaters, outdoor boilers and other outdoor applications. The enclosure includes a body and a cover with the body attaching to the circulator motor. When closed, the enclosure keeps rainfall and other contaminates from entering the wiring space within the enclosure and the circulator motor. The body of the enclosure has multiple ports for electrical wiring inputs for power and for controls connections which can be made with flexible cords and/or hardwires. The outdoor enclosure can be equipped with a terminal strip to simplify wiring and/or with a timer to control when the circulator operates. To avoid problems associated with freezing, the enclosure may include a thermal device that turns the circulator on if temperatures drop. To secure the cover to the body, fastener tabs are included that can accept a screw or lock.

Abstract: An easily manageable device and a method used as an early warning system would be desirable. The device should be usable at virtually any location and operable with little proficiency, and it should be sterilizable, resource-saving and inexpensive. This is achieved by the following: an attachment for the head of a person, the attachment coupled to a first control unit (T) and comprising electrodes (E1 to E4) for receiving cerebral electrical activity or brain potentials, wherein the electrodes lead to the first control unit (T). The first control unit (T) has a microprocessor which is capable of recording signals from the electrodes (E1 to E4) in a time-related manner via an analog-to-digital converter. The first control unit (T) is coupled to or actuates an actuator element (A1), which is capable (LDZ1) of releasing a fragrance in pulses as a stimulus in a flow from at least one pressurized cartridge (K1). The signals of the electrodes (E1 to E4) have an EEG signal level in order to record (FIG. 5, FIG.

Abstract: A bypass valve is for support between hot and cold water lines that connect to respective hot and cold fixtures. The bypass valve includes a valve body having an internal chamber, a hot water inlet port, a hot water outlet port and a discharge port; a bi-metal spring; a support member for mounting the bi-metal spring within the internal chamber of the valve body; and a shuttle mounted to the bi-metal spring and constructed and arranged to mate with the hot water inlet port in a closed position of the bi-metal spring. The bi-metal spring assumes an open position to disengage from the hot water inlet port at a predetermined water temperature to enable the hot water to discharge through the discharge port to the cold water line.
