Abstract: Apparatus, systems and methods of using 70 CFM ventilation fans with heaters for bathrooms having depressibly engageable and depressibly releaseable light covers. The novel ventilation fans and heaters can be mounted to structure in ceilings and inside walls with telescoping suspension brackets that are affixed directly to separate sides of the housing to support the housing against joists and structural supports behind the ceiling. Adjustable louvers on the grill cover allow for outgoing heated air to travel in a different direction into a space from the incoming air travelling into the housing. Plastic type housings around blower wheels reduce undesirable noise effects. Light covers can be easily opened and closed by using depressible engageable fasteners, and depressible release fasteners.

Abstract: Apparatus, systems and methods of generating 70 (seventy) CFM (cubic feet per minute) from ventilation fans for bathrooms with flush mount lights and having the motor partially inside and beneath the blower wheel. A one piece or multipiece housing for the bath fan can be attached to joists in the ceiling by a long telescoping mounting bracket, and a short telescoping mounting bracket that are each directly mounted on opposite outer side walls of the housing. A decorative pan about the light can have vents that receive the incoming air into the fan, which is exhausted therefrom by the motor driven blower.

Abstract: Apparatus, systems and methods of 70 (seventy) CFM (cubic feet per minute) ventilation fans for bathrooms with recessed can with light and having the motor partially inside and beneath the blower wheel. A housing for the bath fan can be attached to joists in the ceiling by a long telescoping mounting brackets. The motor and blower wheel can be attached to a mounting plate inside of the housing, which can be removed as a single unit to allow the motor to be easily replaced or repaired, and also to allow for the inside of the housing to be inspected during and after installation of the exhaust fan. A ring about the light can have vents that receive incoming air into the fan, which is exhausted therefrom by the blower. Seals such as elastomeric rings can seal the bottom of the can to the light, and the top end of the can to the decorative ring shaped pan. A vertical panel can separate a first compartment having the motor and blower from a second adjacent compartment having the light.

Abstract: Apparatus, systems and methods of 80/90 CFM ventilation exhaust fans for bathrooms with telescoping side extension brackets and side by side electric driven motor and blower wheel, and being used with or without lights. The exhaust fans can include a single main housing, that allows for a blower housing to support the motor and a blower wheel in a side by side arrangement. The exhaust fans can further include an outside wiring box that is externally located to the main housing. The wiring box can have support male plugs and female receptacles for supplying an electrical power supply to the electric motor and light. The side extension brackets can include telescoping members that allow the exhaust fans to be easily attached to structural members inside of a ceiling so that the exhaust fan has a vent cover attached to the ceiling. Inside of the exhaust fans can be light box with closed sides and bottom which prevents incoming air from passing directly onto the lights.

Abstract: Apparatus, systems and methods of 50/60 CFM exhaust and ventilation fans for bathrooms with flaps/ears that allow the housings to mount directly to joists and/or other structural members inside of a ceiling or inside of a wall. The housing can include a mounting plate having a motor with attached impeller thereon, wherein the mounting plate with motor and attached impeller can be removed as a single unit from the housing for accessing and inspecting interior wire connections during inspection and for ease in replacing parts such as burned out motors overtime.

Abstract: Apparatus, systems and methods of 110 (one hundred ten) CFM (cubic feet per minute) generating ventilation fans for bathrooms with grill covers and with or without lights in the grill covers. Spring clip type washers can attach the grill covers to the housings. Suspension brackets directly attached to outer side walls of the housing can support the housings. One suspension bracket can be mounted on a bottom wall of the housing and another suspension bracket of equal length can be mounted on a side wall of the housing that is oriented perpendicular to the bottom wall. Bent flanges on the suspension brackets can be on opposite ends of the respective brackets. A lens cover can cover a light box that holds light sources centrally located in the grill cover. The grill cover can include vent openings that allow incoming air to bypass the light sources that can be located inside of the light box.

Abstract: Apparatus for fabricating an array of aligned optical elements. A base tool is used to receive and align a planar material such as a glass sheet. A template tool is used to deposit secondary mirrors and adhesive patches onto the glass sheet. The adhesive patches are used to receive and mount primary mirrors. The primary mirrors are selectively held by an assembly tool. The primary mirrors are brought into alignment with the glass sheet by using actuators on the base tool and by using a registration mechanism to align the assembly tool with the glass sheet.

Abstract: In one embodiment, an apparatus includes a housing. The housing includes one or more units where each unit includes one or more optical elements. The optical elements are configured to concentrate electromagnetic radiation, such as light, from a larger area to a smaller focused area. The optical elements may be sealed in the housing. A removable device is included that is configured to be inserted into a unit. The removable device includes a photovoltaic cell that is configured to receive at least a portion of the concentrated electromagnetic radiation. The removable device is configured to be removable from the housing from a second side of the housing without breaking the seal on the first side of the housing. Accordingly, when the removable device needs to be removed, it can be removed without breaking the seal on the first side of the housing.
