Abstract:
A hinge assembly includes a first arm, a second arm, a rotatable pin coupling, and a power transfer conduit. The rotatable pin coupling rotationally couples the second arm to the first arm. The first arm defines a first portion of a channel, the second arm defines a second portion of the channel, and rotatable pin coupling defines a third portion of the channel. The power transfer conduit extends through the first portion of the channel at the first arm, the third portion of the channel at the rotatable pin coupling, and the second portion of the channel at the second arm.
Abstract:
A driver for an electrically dynamic structure may store and release energy during polarity cycling to improve the energy efficiency of operation. In some examples, the driver includes an energy storage element. In operation, the driver can charge an electrically controllable optically active material to a first operating voltage at a first polarity and subsequently discharge the optically active material during polarity reversal. The driver may store energy released from the optically active material during discharging and subsequently release the energy to charge the optically active material to a second operating voltage at a second polarity different than the first polarity.
Abstract:
A controllable privacy structure, such as a window or door, may include an electrically controllable optically active material connected to a driver. The driver can control the application and/or removal of electrical energy to the optically active material to transition from a scattering state in which visibility through the structure is inhibited to a transparent state in which visibility through the structure is comparatively clear. The driver may need to be located in relatively close physical proximity to the privacy structure the driver is intended to control. Devices, systems, and techniques are described for discretely positioning a driver relative to a privacy structure to be controlled.
Abstract:
Embodiments (10) of the present invention provide methods and equipment for automatically assembling three panes of glass (212.214,216) and corresponding spacers (218,222) so that air or other gas can be injected into the two between-pane spaces (914,916). The equipment (12) can receive two glass panes (212,216) that each have spacers (218,222) coupled to one of their major surfaces, along with a third glass pane (214) having no spacer coupled to its major surfaces, and can assemble the three glass panes (212,214,216) into a "teepee" configuration in which the two spacers (218,222) each contact two of the glass panes along a common edge of the glass panes. Preferred equipment (10) can receive a glass pane (212) in a first orientation and rotate the glass pane 1800 to a second orientation in which the glass pane's two major surfaces face opposite directions from the first orientation. Such preferred equipment (10) can then receive a two-pane teepee (214,216) from a previous piece of equipment (12) and can add the "flipped" single glass pane (212) to the teepee (214,216) to create a three-pane teepee (212,214,216).
Abstract:
A photovoltaic glazing assembly including first and second substrates, at least one being formed of a light transmitting material. The assembly includes a photovoltaic coating over at least the central region of a surface of the first substrate or the second substrate. In some embodiments, a seal system encloses a gas space between the substrates and optionally has a thickness of between approximately 0.01 inch and approximately 0.1 inch. Certain embodiments provide a flexible and electrically non- conductive retention film over the photovoltaic coating. Additionally or alternatively, the assembly can have a peripheral seal system with relative dimensions in certain ranges. Advantageous manufacturing methods are also provided.
Abstract:
Some methods, and corresponding apparatus, for manufacturing photovoltaic subassemblies cause a plurality of desiccant beads to be adhered to an adhesive surface of sheet-like material; the sheet-like material is then, preferably, adhered to an exposed surface of a flexible and electrically non-conductive film, that covers a photovoltaic coating of a first substrate of the subassembly, such that the desiccant beads are held between the sheet-like material and the exposed surface. Some other methods, either alternatively or in addition to the above, include steps for applying the film, that covers the photovoltaic coating, wherein an opening, through the film, is cut, and then aligned, with lead wires of the photovoltaic coating, in the midst of applying the film.
Abstract:
Methods and apparatus for handling material for the insulating glass industry are disclosed. One method of handling material for the insulating glass industry in accordance with the present invention includes the step of arranging a plurality of bars into a plurality of stacks with adjacent stacks defining spaces dimensioned to receive a bar engaging member. The stacks of bars may then be transported to a desired destination. A bar engaging member may be inserted into a space defined by the stacks, and one or more bars may be grasped using the bar engaging member. A container for handling material for the insulating glass industry is also disclosed. The container may advantageously include a plurality of prearranged bar locating members configured to hold a predetermined type of bar stock.
Abstract:
Method of fabricating an assembly comprising spraying a deposit forming material (1249) to at least a portion of the periphery of a glass pane unit, e.g. an insulating unit (1208). Masks (1237, 1237') are first applied to the outside surfaces of the panes (1220, 1222). The deposit (1249) may also cover the edge seal of the insulating glazing unit.
Abstract:
The connector key (30) can include a top central depression (42), side walls (46, 48) having top gaps (60, 62), side shoulders (52) having channels and recesses (64). Connector keys can also have holes through the bottom floor of the central depression (42) to the bottom of a connector key (30) and further through bottom channels (76, 78) provided in the connector key (30). Holes may be punched through the spacer material, preferably forming jagged portions which secure the spacer members to the connecting key (30). Sealant may be injected through the punched holes, and through the through holes in the connector key central depression floor. Injected sealant may thus flow into the central depression (42), over the side walls (46, 48) into the side recesses (64), and into the bottom channels (76, 78).
Abstract:
A heat-resistant transparent glass article is formed with an inner sandwich structure comprising a metallic infrared-reflective metal film sandwiched between thin protective silicon films, the inner sandwich structure in turn being sandwiched between transparent dielectric films and the film stack being deposited upon a glass substrate. One or both of the transparent dielectric films may also contain silicon.
