Abstract: An electrostatic transducer, a diaphragm (2) therefor, and corresponding methods of manufacture are disclosed. The electrostatic transducer is preferably for use in a motor vehicle. A composite laminated diaphragm (2) is manufactured by providing a first insulating layer (4), providing a conductive layer (6) on a surface of the first insulating layer (4), and bonding a second insulating layer (10) to the conductive layer (6) such that the second insulating layer (10) extends over the conductive layer (6). The first and second insulating layers (4, 10) each comprise a sheet of uncharged insulating material. The thickness of the composite laminated diaphragm (2) is less than 20 ?m.

Abstract: Disclosed is a multipart valve assembly. The assembly can be used in selectively coupling two vehicles. The assembly includes inter-fitting male and female components and associated control valves. Coupling the male and female components establishes media (fluid or gas), communications, and electrical paths between space vehicles. This permits the passage of media from one vehicle to the other and likewise enables one vehicle to operate the control valve of the other vehicle.

Abstract: A non-magnetic latching servo actuated valve under the control of a controller comprising a motor in rotational communication with a lead screw. The lead screw advances or retracts a valve stem connected to a valve stem cap. The valve stem cap has a valve stem cap passage. A valve end cap having a valve seat is provided and receives the valve stem cap such that the valve stem cap can contact the valve seat. A pressure relief device or shuttle assembly is positioned internal to the valve stem cap. The shuttle assembly is used for venting build-up downstream pressure through the non-magnetic latching servo actuated valve outlet, through the valve stem cap passage, around the shuttle assembly, through passages, into a pressure chamber, and to the nonmagnetic latching servo actuated valve exit where the fluid vents until the system is in balance.
