Abstract: A system for upgrading firmware in multiple units or devices of a building control or automation system. A computer may have a tool that can reflash the firmware with an upgrade. The tool may reflash the firmware of multiple devices automatically without intervention of an operator. Devices having firmware that need an upgrade may be identified and classified as eligible for a firmware upgrade. Devices having firmware similar to firmware in other devices may be grouped with the latter devices for upgrading together, sequentially or in parallel, to simplify and expedite firmware upgrading of the devices. Firmware of devices in the field may be upgraded via a communication network or the like by the computer with the tool. The firmware upgrade, communications and/or associated activity associated with the upgrade may be proprietary and/or secured from public availability.

Abstract: A system and approach for defining labels for values, such as ordinal numbers, of enumerated parameters in a wall module. Label and number pairs may be downloaded to a wall module as part of definitions of the parameters. The wall module may be a source of a list of labels to a user and then set each parameter to a value associated with a label selected by the user.

Abstract: An electronic device such as an HVAC controller that accounts for internal heating in determining an environmental condition such as temperature or humidity in the space surrounding the HVAC controller. The HVAC controller may calculate a transient heat rise value that is based upon a powered time period and a first order time lag, especially during a time period before which the HVAC controller reaches a steady state temperature condition.

Abstract: A vacuum cleaner comprises a hair collection assembly having a hair collection element adapted to collection hair from a surface. The hair collection assembly can be mounted to the cleaning head of the vacuum cleaner for movement between a use position in which the hair collection element is in contact with the surface and a second position in which the hair collection element in spaced from the surface. The hair collection element can further be configured to collect hair from the surface when the cleaning head is moved in a first direction and to not collect hair from the surface when the cleaning head is moved in a second direction. A method of removing hair from a surface is also described.

Abstract: A canister vacuum cleaner comprises a base, a recovery tank, and a clean solution tank. The vacuum cleaner can be used for dry vacuuming, wet vacuuming, and can distribute cleaning solution to a floor surface and has means for a fluid distribution system and a recovery system. The clean solution tank can be filled with a cleaning solution for distribution to a floor surface and the recovery tank is used for collecting dry or liquid matter recovered from vacuuming.

Abstract: A surface cleaning apparatus comprises a fluid delivery system including a supply of cleaning fluid and a fluid recovery system for drawing dirty cleaning fluid from the surface to be cleaned. The apparatus can comprise a passageway that passes heated motor cooling air in heat exchange with the cleaning fluid to heat the cleaning fluid. The apparatus can further comprise a mixing manifold that mixes first and second cleaning fluids at different concentrations for different cleaning modes. The apparatus can further comprise a fluid valve having a shape memory alloy actuator.

Abstract: A hand-held nozzle is attached to the end of a vacuum and fluid delivery hose of an upright deep cleaner. The nozzle includes a reservoir to contain a solution to be applied to a surface. When a solution delivery system of the deep cleaner is pressurized, water from the upright cleaner clean water tank is routed through the hose to the hand-held nozzle. The water is routed through a venturi valve connected to the reservoir, which draws the solution to the valve to mix with the water stream. The resultant mixture flows from the hand-held nozzle for application to a surface being treated. One embodiment of the solution reservoir includes a retainer cap bonded to the reservoir and utilizing a bayonet-type mounting arrangement for mounting the reservoir to a nozzle assembly.

Abstract: A portable surface cleaning apparatus has a base for movement along a surface to be cleaned and an upright handle pivotally attached to a rearward portion of the base. A fluid dispensing nozzle for applying fluid to the surface and a suction nozzle for picking up fluid and debris from the surface are associated with the base. A clean water holding tank and a detergent holding tank are removably mounted to the handle while a recovery tank is removably mounted to the base. A mixing valve is fluidly connected between the holding tanks and the spray nozzle for changing the mixing ratio of the detergent with respect to the water. The fluid recovery tank includes an integrally molded conduit that extends from the suction nozzle and a mounting for an accessory hose that interrupts the fluid path from the suction nozzle in the conduit and redirects fluid flow through the hose.

Abstract: A device for allowing inspection of foreign matter in a stream of fluid flow in a conduit includes a filter disposed transversely in the fluid flow for filtering and collecting foreign matter from the fluid flow passing therethrough. A support frame supports the filter and allows connection to the conduit. A filter retainer is connected to the support frame for retaining the filter therebetween and has a first position disposed transversely in the fluid flow. A first pivotal member interconnects the filter retainer and the support frame for allowing pivotal movement of the filter retainer in a direction substantially perpendicular to the fluid flow from the first position to a second position outside the fluid flow to allow the filter to be removed and inspected.
