Abstract: A provided wireless wallbox dimmer may accommodate a plurality of button configurations. The dimmer may be configured to contain a variable number of controllably conductive devices. The dimmer may include a yoke that defines a first plane and an antenna that defines a second plane that is substantially parallel to and spaced apart from the first plane. The yoke may have a flange that is oriented angularly offset relative to the first plane and provides a plurality of mounting locations for controllably conductive devices. The antenna may provide the dimmer with a first wireless transmission range. The dimmer may include a faceplate that cooperates with the antenna to provide the dimmer with a second wireless transmission range that is broader than the first wireless transmission range. The dimmer may include a button assembly that is supported independently of the yoke.

Abstract: A bleed valve for a gas turbine engine includes a housing that defines an inlet upstream from an outlet. The bleed valve includes a poppet movable relative to the housing between a first position, in which the poppet closes the inlet, and a second position, in which the inlet is open and configured to receive a fluid flow. The housing defines a tortuous path for the fluid flow from the inlet to the outlet configured to reduce a pressure of the fluid flow from the inlet to the outlet within the housing. The tortuous path is defined by a plurality of rings positioned about the poppet, with each ring of the plurality of rings spaced apart from an adjacent ring of the plurality of rings between the inlet and the outlet to define the tortuous path.

Abstract: Airfield guidance signs are described herein. One airfield guidance sign includes a first surface, a second surface angled with respect to the first surface, and a top edge adjacent the first surface and the second surface, wherein the top edge is rounded to reduce a pressure differential between the first surface and the second surface when a force is applied to the first surface or the second surface.

Abstract: A thrust reverser system comprising a single row vane assembly is provided. The provided thrust reverser system is capable of meeting performance requirements for turbine engines with reduced weight and cost.

Abstract: A thrust reverser system having an asymmetric vane assembly is provided. The provided thrust reverser system generates a desired vertical thrust component that at least partially offsets a potential nose-up pitch moment. The provided thrust reverser system employs a single row asymmetric vane geometry that reduces weight and material cost.

Abstract: An inlet particle separator system for a vehicle engine includes a hub section, a shroud section, and a splitter. The hub section has a hub outer surface that diverges, relative to the axis of symmetry, to a hub apex. The shroud section has a shroud inner surface that surrounds, and is spaced apart from, at least a portion of the hub section to define a main flow passageway between the hub outer surface and the shroud inner surface. The splitter is disposed downstream of the air inlet and extends into the main flow passageway to divide the main flow passageway into a scavenge flow path and an engine flow path. The hub section and the shroud section are configured such that the cross sectional flow area of the main flow passageway decreases downstream of the air inlet to define a throat section that is disposed upstream of the hub apex.

Abstract: A multi-channel particle separator includes a plurality of vanes. Each vane is spaced apart from at least one other adjacent vane to define a flow channel, and includes a leading edge, a trailing edge, a first side wall, a second sidewall, and a splitter. The first side wall extends between the leading edge and the trailing edge. The second side wall is spaced apart from the first side wall and extends from the leading edge toward the trailing edge. The splitter may be rotationally coupled to the trailing edge and extend toward the leading edge. The splitter is spaced apart from the first side wall to define a scavenge volume and is rotatable between an extended position and a retracted position. The vanes may also or instead be coupled to a ring-shaped structure.

Abstract: An inlet particle separator system includes a shroud section and a hub section that is at least partly surrounded by the shroud section. The hub section is spaced apart from the shroud section. The inlet particle separator system also includes a flow passageway with an air inlet defined between the hub section and the shroud section. The flow passageway branches downstream of the air inlet into a main passage and a pre-cleaner passage. The main passage is defined between the hub section and the shroud section. The pre-cleaner passage includes a pre-cleaner inlet and extends at least partially through the hub section. Furthermore, the system includes a splitter that divides the main passage into scavenge and engine flow paths. The pre-cleaner inlet is partly defined by a first surface of the hub section. The first surface faces substantially in an upstream direction toward the air inlet.

Abstract: A thrust reverser system for a turbine engine includes a support structure, a transcowl, and a door. The transcowl is mounted on the support structure and is axially translatable, relative to the support structure, between first and second positions. The door is pivotally coupled to the support structure and is rotatable, about a pivot axis, between stowed and deployed positions when the transcowl translates between the first and second positions, respectively. The door has an internal surface and a balance plane, and pressure forces acting along the balance plane effectively creates no moment about the pivot axis. The internal surface of the door has a first surface area forward of the balance plane and a second surface area aft of the balance plane, and the second surface area substantially exceeds the first surface area.

Abstract: A golf club iron employs an elongated connection member to connect the lower end of a golf club shaft directly to the rear face of the golf club head over an elongated region between the top surface and the sole of the head. The connection region includes a line which is directly behind the center of mass of the head to enhance the transfer of energy to a golf ball where little or reduced torque is produced by off-center hits.

Abstract: The golf club practice device of the present invention includes a supporting member, an elongated member and a connecting member which form means for perfecting a golfer's swing. The supporting member supports the device on a generally planar base from which a positioned golf ball may be driven such as a golf swing practice area or a plate covered with a mat of a synthetic material. The connecting member makes right angle elbow connections with one end of the elongated member and with the end of the supporting member distal the planar base. The elongated and connecting members are substantially parallel to the planar base. A golf ball may be positioned on the planar base under the connecting member between the elbow connections of the elongated and supporting members so that the golf ball would just be completely visible to the user.
