Abstract: A system and method for configuring a water heater. The method includes capturing, with a mobile device a scannable feature of a rating plate and receiving, with the mobile device, an input indicative of a configuration selection. The method further includes configuring, with the mobile device, the water heater based on the configuration selection.

Abstract: In a method of treating a gas stream (32) containing combustible and/or reactive particles (34) at least a part of the particles (34) contained in the gas stream (32) is separated from the gas stream (32) by means of a separation device (36). The particles (34) separated from the gas stream (32) by means of the separation device (36) are supplied to a collecting vessel (40). The supply of particles (34) to the collecting vessel (40) is interrupted. A flame retardant material (57) is supplied to the collecting vessel (40) so as to form a cover layer of flame retardant material (57) on the particles (34) contained in the collecting vessel (40).

Abstract: A system and method for configuring a water heater. The method includes capturing, with a mobile device a scannable feature of a rating plate, establishing a network connection between the mobile device and a server, transmitting information captured from the scannable feature by the mobile device to the server over the network connection, receiving from the server to the mobile device a plurality of water heater configurations in response to the information, receiving, with the mobile device, an input indicative of a configuration selection selected from the plurality of water heater configurations, and transmitting configuration information from the mobile device to the water heater to configure the water heater based on the configuration selection.

Abstract: A ventilator system includes: a control system having a controller and a user interface; and a pneumatic system having an inspiratory channel and an expiratory channel. The inspiratory channel further comprises a blower connected to an oxygen source, wherein the blower is configured to be controlled by the controller, and to deliver oxygen and/or air to a patient via the inspiratory channel. The expiratory channel includes an exhaust valve configured to be controlled by the controller and an outlet. The pneumatic system further includes a plurality of sensors configured to provide oxygen measurements, pressure measurements, and flow measurements. The controller is configured to receive a user input via the user interface for controlling a treatment regimen for the patient, and to control the blower and the exhaust valve according to the treatment regimen.

Abstract: In a method for treating combustible and/or reactive particles (34) which have been separated from a gas stream (32) by means of a separation device (36) an oxidizing agent is supplied to an atmosphere surrounding the particles (34) so as to cause a passivating oxidation of at least a part of the particles (34). A content of the oxidizing agent in the atmosphere surrounding the particles (34) is detected and the supply of the oxidizing agent to the atmosphere surrounding the particles (34) is controlled in dependence on the detected content of the oxidizing agent in the atmosphere surrounding the particles (34).

Abstract: Approaches for an emergency power off (EPO) power island, for saving critical data to non-volatile memory in the event of an EPO condition, for use in a hard-disk drive (HDD) storage device. The EPO power island includes a controller for detecting an EPO condition. A voltage regulator supplies power from spindle motor back EMF only to the EPO power island and to the non-volatile memory. Thus, the remainder of the hard drive controller (HDC) is isolated from the EPO power island so that it will not corrupt the data as the HDC's power supply is decaying. Using the power provided by the voltage regulator, the EPO power island transfers critical data from a memory internal to the island to a non-volatile memory external to the island, such as to a flash memory chip.

Abstract: Methods and systems for evaluating the condition of a water tank having a powered anode protection system. The water heater includes a storage tank to hold water, a powered anode, and a control circuit. The control circuit includes a variable voltage supply, a voltage sensor, and a current sensor. The control circuit is configured to compare a measured parameter to a threshold. In some constructions, the threshold is indicative of a condition of the storage tank at which the powered anode is no longer able to protect the storage tank from corrosion. In other constructions, the threshold is predicative of a potential failure of the storage tank caused by corrosion. In some constructions, the control circuit is configured to estimate a time remaining until the predicted failure of the storage tank.

Abstract: An appliance is disclosed that includes an electrically operated load such as a gas-fired appliance having an electrically operated gas valve. A current sensing circuit is configured to sense the current provided to the load. Based upon this sensed current, it is determined whether the load is energized. Methods are also disclosed for monitoring the status of a current sensing circuit to determine the actual operating state of the load.

Abstract: A gas-fired appliance is disclosed that includes a gas valve powered by a power source. A plurality of switching units, each responsive to a condition of the appliance, are arranged in series between the gas valve and the power source. Each switching unit includes an emitter, such as an emitter of an optocoupler, that is used to monitor the opened or closed status of a switch in the switching unit. When at least one switch opens, power to the gas valve is reduced preventing the gas valve from operating. However, because this reduced power is provided to each subsequent switching unit, each optocoupler can be monitored regardless of the opened or closed status of previous switching units. As such, one or more open switches can be detected simulataneously.
