Abstract: A molded hinge assembly is provided. The molded hinge assembly includes a male portion, a female portion formed unitarily with the male portion, a swivel shaft formed unitarily with the male portion, the swivel shaft including a plurality of channels defined along a rotational axis thereof. The molded hinge assembly also includes a plurality of molding gates formed at an intersection between each respective channel and the female portion, the female portion being subsequently rotatable with respect to the male portion after the molding gates are broken. During operation, the swivel shaft is friction fit within the female portion after the subsequent rotation of the female portion to break the molding gates.

Abstract: A shut-off valve assembly includes a one-piece housing having an inlet and an outlet. During manufacture, the housing is formed with an inlet end plate and a fully open end opposite the end plate. A valve door assembly including a flapper door is secured in the housing, and includes a seal between the flapper door and the housing. The open end is then reformed to provide an outlet from the housing. In a fuel system, a cover assembly is releasably secured to the housing.

Abstract: In one embodiment, the present invention is directed to a data structure for representing a spatial region. The data structure comprises a hierarchical arrangement of nodes associated with a plurality of refinement levels, wherein each node of the hierarchical arrangement of nodes is a regular spatial subdivision of the spatial region or another node that is associated with a preceding refinement level. The hierarchical arrangement of nodes forms a directed acyclic graph. The hierarchical arrangement of nodes comprises at least two nodes that have respective edges that are traversed to a common child node such that the hierarchical arrangement of nodes does not comprise a repeated pattern from any two nodes of a common refinement level of the data structure.

Abstract: A connector is provided between a fuel pipe assembly and a fuel housing. The connector is in substantially fixed position relative to the fuel pipe assembly and has portions thereof which engage the fuel housing, thereby providing a physical connection between the fuel pipe assembly and housing whereby assembly is snap together, and unintended disconnect is inhibited.

Abstract: An airbag sleeve configured to securely retain an airbag includes a main body, a first latching member, and a second latching member. The main body includes first and second edges and defined an airbag retention area. The first latching member is connected to the first edge, while the second latching member is connected to the second edge. The first and second latching members are configured to interlock together in a closed position in order to securely retain the airbag within the airbag retention area. The first and second latching members are also configured to separate from one another when the airbag deploys.

Abstract: A wireless communication (120) device for placing calls within a wireless communication system (100) on a plurality of channels is provided. The wireless communication unit (120) includes a transceiver (204) for transmitting and receiving radio frequency (RF) signals on the plurality of channels, a signal detector (220), a network scanner (222) and a controller (206). The signal detector (220) detects whether a call on one of the plurality of channels has been dropped (304). The network scanner (222) controls which of the plurality of channels the transceiver receives signals on and which of the plurality of channels the transceiver transmits signals on. The controller (206) automatically increases a scan rate (308) of the network scanner (222) in response to the signal detector (220) determining that the call has been dropped (304).

Abstract: Embodiments of the present invention provide a pressure relief assembly that may include an inner shell having at least one air passage, and at least one membrane flap sealingly covering the air passage. The membrane flap is configured to move to open the air passage based on an air pressure level. The assembly may also include an outer shell secured to the inner shell, wherein an air channel is defined between the inner shell and the outer shell. The outer shell is configured to protect said inner shell from moisture. The assembly may also include at least one moisture catching ledge surrounding the air passage. The moisture catching ledge is configured to trap moisture that passes by the membrane flap.

Abstract: A system and method are disclosed which enable post-fabrication reduction of minimum feature size spacing of microcomponents. A method for producing an assembly of microcomponents is provided, in which at least two microcomponents are fabricated having a separation space therebetween. At least one of the microcomponents includes an extension part that is operable to reduce the separation space. Such an extension part may include an extension member that is movably extendable away from its associated microcomponent to reduce the separation space between its associated microcomponent and another microcomponent. The extension part may be latched at a desired position by a latching mechanism. The extension part may be implemented such that the extension member eliminates the separation space, thereby resulting in such extension member engaging another microcomponent. Such engagement may be achieved without requiring power to be applied to the microcomponents.

Abstract: A ground washer is disclosed for attachment by a grounding screw to a grounding terminal. The washer device includes a disc-shaped member which defines an opening for the reception therethrough of the grounding screw. The member has an annular portion having a first and a second surface, the annular portion surrounding the opening. The annular portion cooperates with a plurality of teeth extending from the grounding terminal towards the annular portion of the member. A conical portion having a first and a second end, is disposed concentrically around the annular portion. A raised annular ridge is disposed between the annular portion and the conical portion, the ridge cooperating with the grounding screw such that when the grounding screw is turned, the ridge urges the annular portion into contact with the plurality of teeth of the grounding element. An annular flange is disposed concentrically around the conical portion, the flange mating with the grounding terminal.
