A locally powered intermittent pilot combustion controller may include an igniter, a thermal electric and/or photoelectric device that produces an electrical signal having power when exposed to a flame, and a local power source for providing power when the thermal electric and/or photoelectric device is not exposed to a flame. In some cases, the intermittent pilot combustion controller may include a memory for storing information about an ignition sequence for igniting a pilot flame, and a controller coupled to the memory. The controller may be configured to initiate the ignition sequence of the pilot flame using information stored in the memory, determine whether the ignition was successful by monitoring the electrical signal produced by the thermal electric and/or photoelectric device, and adjust the information stored in the memory based on whether the ignition sequence completed successfully.

Method and system for controlling an ignition sequence for an intermittent flame-powered pilot combustion system

A flame powered intermittent pilot combustion controller may include a first power source and a second power source separate from the first power source, a thermal electric and/or photoelectric device, an igniter and a controller. The thermal electric and/or photoelectric device may charge the first power source when exposed to a flame. The controller and the igniter may receive power from the first power source when the first power source has sufficient available power, and may receive power from the second power source when the first power source does not have sufficient available power.

An oropharyngeal measurement device includes a tubular body, a sealed channel, a radial flange member, and a measurement indicator on the outer surface of the tubular body. The tubular body includes a proximal end and a distal end. The sealed channel extends within the tubular body from the proximal end to the distal end and includes a plurality of bends configured to conform with the airway of a user. The measurement indicator is useful for placing alongside the face of a patient from the mouth towards the throat, in order to gauge an approximation for a oropharyngeal airway device to be used during a medical procedure.

A furnace controller for a modulating furnace that helps provide a balance between energy efficiency and occupant comfort across various burner firing rates and/or across various circulating blower speeds. In some cases, the furnace controller can be configured to permit a user to customize operation of the furnace in accordance with their particular needs and/or desires with respect to efficiency and comfort. A selection may be made between an energy efficiency setting and a user comfort setting. Then, a plenum parameter such as a discharge air temperature (DAT) or discharge air flow (DAF) may be regulated in accordance with the selected setting.

Selectable efficiency versus comfort for modulating furnace

A modulating furnace having a variable rate burner and a controller is operated at a first burner firing rate for a first period of time, and a higher burner firing rate once the first period of time has expired. In some instances, the burner may be operated only while the controller is receiving a call for heat from a thermostat or the like.

A mounting bracket for mounting a temperature sensor, a gas valve, a power delivery unit, a controller and/or any other suitable object or device to a water heater tank. An illustrative but non-limiting example may be found in a mounting bracket that includes a polymeric body that has a sensor portion configured to receive a temperature sensor. The sensor portion may have a distal end that extends into and supports the temperature sensor within the water heater tank. The polymeric body may also includes a threaded portion that is configured to threadably engage a threaded spud in a water heater tank such that the distal end of the sensor portion extends into the water tank of the water heater.

A method and apparatus for determining a health status of a water heating device is disclosed. The water heating device may have a controller that incorporates logic to regulate the heater responsive to water temperatures detected at different areas within the water heating device by first and second sensors. Unfortunately, the first and second sensors may fail. To detect fault conditions or otherwise determine the heath status of the water heating device, a logic unit in the controller may perform a test on the first and/or second sensors so as to provide a test output. The logic unit may also determine whether the test output satisfies one or more predetermined thresholds. These predetermined thresholds may be indicative of a properly-functioning sensor. When the test output does not satisfy the at least one predetermined threshold, the logic unit may then set a fault condition indicative of improperly functioning sensors.

Temperature sensor diagnostic for determining water heater health status

An electromagnetic valve assembly having a dual armature solenoid for controlling two valves is disclosed. In one embodiment, the solenoid may include a first pole piece, a second pole piece spaced from the first pole piece, a coil disposed about at least a portion of the first pole piece, a first armature extending laterally across the first pole piece and the second pole piece, and a second armature extending laterally across the first pole piece and the second pole piece. In one illustrative embodiment, the first armature and the second armature pivot relative to the second pole piece. In another illustrative embodiment, the first armature and the second armature pivot relative to the first pole piece. In yet another illustrative embodiment, the first armature and the second armature pivot relative to opposite pole pieces. In any case, the coil may electromagnetically actuate the first and second armatures to selectively open and/or close corresponding valves or other actuatable components.

Instrument-cartridge interfaces for fluidic analyzers that have an instrument and a removable cartridge are disclosed. For example, and in one illustrative embodiment, the instrument may include a needle that is adapted to penetrate a septum on a removable cartridge. In another illustrative embodiment, the instrument may include a plunger that is adapted to deform a deformable membrane on a removable cartridge. In yet another illustrative embodiment, the instrument may include a nozzle that is adapted to mate and seal with a flow channel on a removable cartridge. Techniques for detecting the flow rate in a flow channel on a removable cartridge, as well as the position of fluid in a flow channel of a removable cartridge, are also disclosed.

Fluid free interface for a fluidic analyzer

A direct current to direct current voltage converter (DC-DC converter) in accordance with the invention comprises a transformer coupled with a voltage source and a self-starting oscillator that includes a secondary winding of the transformer, a capacitor; and a first switch coupled to conduct current from the DC source via a primary winding of the transformer. The first switch is a normally closed switch. The DC-DC converter also comprises a second switch coupled to conduct current in a parallel path with the first switch, the second switch being a normally open switch having a lower saturation resistance than the first switch.
