A steering system (10) for a vehicle (16) comprises a housing (20) having first and second end portions (32, 34) and an intermediate portion (50). A steering member (66) is supported for axial movement in the housing (20). A piston (100) fixed for movement with the steering member (66) has opposite end faces (104, 106). First and second springs (130, 132) engage the end faces (104, 106) of the piston (100) and bias the piston and thereby the steering member (66) in first and second axial directi...

Apparatus (10) for helping to protect an occupant of a vehicle includes an inflatable vehicle occupant protection device (14) inflatable between the vehicle side structure (16) and a vehicle occupant. The device (14) defines an inflatable volume (58) that includes a forward portion (64) and a rearward portion (66). An inflation fluid source (24) is in fluid communication with a fill tube (22) and provides helium inflation fluid for inflating the device (14). The fill tube (22) includes outlet ap...

A method for helping to control a vehicle occupant protection device (22) includes taking an image of the vehicle interior with a digital imager (50) having an array of pixels (53). A contiguous portion of the image less than the entire image is selected. At least one image enhancement technique is applied to the selected image portion. The enhanced image portion is combined with the other portions of the image to make an enhanced image. The enhanced image is analyzed to detect at least one of f...

An imaging system (50) for providing vehicle security and convenience features that employs face recognition software to identify and track a person. The system (50) employs infrared emitters (30) that emit an infrared signal along a predetermined field-of-view, and an infrared sensor (34), such as a CMOS sensor used as a video signal array, that receives reflected infrared illumination from objects in the field-of-view. A processor (52) including the face recognition software, is employed to de...

A connector for interconnecting two conductors comprises a plug component for mating engagement with a receptacle component. The plug component has a conductor means therein and a first elastomeric sealing membrance covering the mating end thereof to seal the same, the sealing membrane having a slit therein. The receptacle component includes conductor receiving means therein and a second elastomeric sealing membrane covering the mating end thereof to seal the same. The second sealing membrane al...

An extrusion die of the type particularly suited for use in underwater pelletizing of polymeric materials. The die includes a die body having a forward end face with a plurality of extrusion ports passing therethrough terminating at the forward end face. A layer of insulating material is interposed between the forward end face at the area of the extrusion ports and a subplate which is constructed from the same material as the die body. The subplate is fixedly secured to the die body so as to for...

An active semiconductor device, such as a Gunn effect device, capable of operation at extremely high frequencies, fabricated in situ on a substrate that also serves as a dielectric waveguide to propagate energy from the device. In the embodiment disclosed, a Gunn effect diode is formed on a substrate of gallium arsenide (GaAs), together with a cavity region and a metalized heat sink layer permitting operation at relatively high power levels. A bias current is applied through a conductive strip a...

The present invention resides in a dual fueled burner gun providing reduced production of oxides of nitrogen. The gun operates in a gaseous fueled mode when it is charged with a gaseous fuel or in a liquid fueled mode when it is charged with a liquid fuel. The gun may also operate in a gaseous/liquid fueled mode in which it is charged with both the gaseous and liquid fuels.

A controlled scintillation rate decoy having microwave reflectors for reflecting incident radar energy in a manner to provide the decoy with a selected radar cross-section, and variable electrical impedance control means connected in electrical circuit with the reflectors for controlling the scintillation magnitude or scintillation rate of the decoy.

Although the method and apparatus of the present invention can be utilized to apply either a uniform or a nonuniform covering of material over many different workpieces, the apparatus (20) is advantageously utilized to apply a thermal barrier covering (64) to an airfoil (22) which is used in a turbine engine. The airfoil is held by a gripper assembly (86) while a spray gun (24) is effective to apply the covering over the airfoil. When a portion of the covering has been applied, a sensor (28) is ...
