  • Patent number: 10718529
    Abstract: Provided is a method for controlling the operation of a cooking appliance, such as an oven range. The cooking appliance includes a door with multiple spaced apart glass panels. The method uses an interlocking mechanism that interferes with the installation of at least one of the plurality of glass panels in the door if at least one of the glass panels is not installed properly. The method further uses a switch with a plunger can be installed in the door, which allows the appliance to operate only when a failsafe electrical circuit is closed corresponding to a selected position of the plunger when the door is closed. The plunger is prevented from retaining that selected position if at least one of the glass panels is improperly installed or if a top cap is not properly seated or installed above the glass panels.

  • Patent number: 9170033
    Abstract: Images representative of cloud shadows with respect to a field of heliostats can be used to adjust operation of a solar energy system. For example, images of a field of heliostats and shadows produced by the clouds can be obtained. Additionally or alternatively, images of the sky and clouds can be obtained. The images can be analyzed to determine a shading parameter. Based on the shading parameter, an operating parameter of the solar energy system can be changed or maintained. For example, the operating parameter may include aiming directions for one or more of the heliostats. Cloud characteristics in addition to the location of the cloud shadow can be used in determining the shading parameter. Such characteristics can be used in determining if and/or how to change the operating parameter of the solar energy system.

  • Patent number: 9010316
    Abstract: A housing has a bottom, side panels, end panels, and a top, forming a chamber. The side and end panels have interior sections and slidable exterior sections. A solar energy collector, tubing or solar panels, is within the chamber. A cover plate is fabricated of a transparent material and is secured to the exterior section adjacent to the top. Lenses are coupled to the exterior section, and focus sunlight on the solar energy collector. Lift drivers vary the elevation of the lenses with respect to the solar energy collector. A gimbal assembly with a tilt driver operatively couples the housing to the roof to vary the angular tilt of the housing. A light sensor, a temperature sensor, and an associated controller adjust the elevation of the lenses and the tilt of the housing.

  • Patent number: 9006560
    Abstract: A lightweight reflector with a load bearing structure based on a tensile spoke-wheel. The spoke structure is especially compatible with dish parabolic mirrors, but has utility as a carrier structure for any round functional surface, including flat or slightly-curved mirrors used in central tower solar systems, parabolic dishes for radio telescopes and antennas, and for non-concentrating thin film solar panels. There are no radial members loaded in compression. All the spokes pull the rim inwards, and the rim is compressed in the circumferential direction. The imbalance in spoke tension results from the application of load provides the rigidity of the rim in respect to the hub, both for in-plane and out-of-plane forces. Ribs stiffen the spokes to resist wind and gravity, but are not structurally supported by either the hub or the rim. Lightweight reflector tiles match the wheel structure and create the reflective surface.
