The disclosed technology includes systems and methods for detecting an obstructed air filter in a furnace. The disclosed technology can include a method and system that includes an air inlet, an air filter for filtering particles from air passing through the air inlet, an air moving device, a fuel valve, a burner, a pressure sensor, and a controller in communication with the pressure sensor and configured to output an alarm signal when the controller receives differential pressure data from the pressure sensor that indicates that the air filter is obstructed.

Systems and methods of detecting an obstructed furnace air filter using a pressure sensor

A fuel-fired heating appliance comprises a fuel source, an air source, a chamber in which fuel and air mix, a burner downstream from the mixing chamber, an igniter proximate the burner, a heat exchanger, a blower and a flue pipe. An ambient air inlet may be defined by at least one of the outlet end of the blower and the flue pipe extending between the interior of the flue pipe and an area ambient to the flue pipe. A flow rate of combustion gas may be controlled to a level below a steady-state flow rate during appliance warm-up.

Fuel-fired appliance with exhaust dilution

Disclosed herein are interface devices and systems. In one aspect, a haptic interface device includes at least one position detection module configured to determine positional data for determining a position of at least one portion of at least one body part of the user; at least one tensile element or compressive element coupled to the at least one body part and configured to produce at least one of: a predetermined range of motion and applied force to a coupled body part; and at least one haptic feedback module configured to produce force feedback or tactile sensation to the at least one body part, the feedback module comprising: at least one motion control module configured to control motion of the at least one body part; and at least one force sensor configured to determine applied force data generated from the at least one body part. Also disclosed herein are methods for using the disclosed devices and systems.
