摘要： The disclosure concerns steps interchangeable into a platform lift, such as for wheelchairs for vehicles. Such a convertible step lift comprises a frame mounted in a rectangular notched-out floor section, which frame comprises corner posts which also act as guides for up and down movement of the platform lift. The movable platform comprises three sections foldable into a lower step, a riser, and an upper step, which sections are pivoted on shafts along their adjacent edges. The pivot shaft for upper step section and riser also is connected to reciprocating motor means for raising and lowering the platform. Lever extensions are fixedly attached to the ends of the riser, which are pivotally connected to other reciprocating motor means which unfolds the riser from an acute angle under the upper step section into a position coplanar with the upper step and at the same time moves the lower step section horizontally outwardly and upwardly into the same coplane to form the platform. At the outer edge of the lower step section is another shaft to which a barrier plate and a ramp are pivoted and normally urged into their operative positions when the step sections are in platform position. The barrier is folded down by levers and links when the platform engages the ground. An additional lever connected to an end of the riser folds the ramp and the barrier into their inoperative positions when the sections are in their step position.

摘要： A wheelchair lift such as for vehicles, comprising a stationary outer rectangular frame across the top of which swings an inner rectangular telescopic frame, the lower telescoping end of which has a foldable platform for the wheelchair. The inner frame swings out to clear the side of the vehicle, which swinging movement is limited by a pair of toggles that support a bridging platform between the lift platform and the floor of the vehicle. An electric motor-driven hydraulic pump, valve, and accumulator assembly provides the power for lifting the platform by telescoping the inner frame parts, and a valve in the hydraulic system damps the lowering of the platform. The folding of the platform from a vertical to a horizontal position and swinging of the inner frame may be done manually or by a separate reciprocating motor mounted on the upper telescopic frame.

摘要： An optical detection apparatus includes a housing having a circumferential opening therein. A primary mirror reflects light rays to form a first set of light rays to a secondary mirror that has a generally concave shape coupled to the housing. A tertiary mirror having a generally concave shape coupled to the housing spaced apart from the secondary mirror directs light to detection optics that form an image using the third set of light rays. The detection optics include a micro-mirror array that redirect the image to a detector. A controller controls the micro-mirror array and determines an event characteristic based upon the image thereon.

摘要： Systems and methods to control projection of a pattern are provided. A particular method includes receiving first three-dimensional coordinates that specify one or more locations on a surface of a workpiece where the one or more locations correspond to a part definition to be projected onto the surface. The method also includes computing scan angles for a scanning system based on the first three-dimensional coordinates. The scan angles specify angles used by the scanning system to direct a beam of light to project the part definition onto the surface. The method also includes sending control signals to the scanning system based on the scan angles.

摘要： A system and method for free space, optical remote sensing of a potential threat agent using spectrally responsive sensor material. In one example the sensor material is formed by particles, which in one particular form are porous photonic crystals. The particles are dispersed into an area being monitored for the presence of the potential threat agent. A pair of lasers is used to generate optical light beams that are directed at the sensor particles after the particles have been dispersed. The light reflected by the sensor particles is then analyzed. The presence of the potential threat agent causes a shift in the spectral peak of light reflected from the sensor particles that can be sensed using photo detectors and a processing subsystem. The system can be tuned to remotely detect for specific chemical, biological or environmental agents that may be present within a given area.

摘要： Apparatus and methods for calibrating an optical detector. In one embodiment an optical reference apparatus includes a body having an outer surface. At least a portion of the outer surface has a reflectance that can vary. The optical reference apparatus is adapted to be deployed with a cloud of optical sensors and has a terminal velocity that is about the same as the terminal velocity of the sensors. Further, the variation of the reflectance can be caused by a rotation of the optical reference apparatus (caused by an aerodynamic member). The sensors may be made from porous silicon and the optical reference apparatus may include a retroreflector. The apparatus also provides a method of referencing an optical signal. The method includes deploying an optical reference apparatus with a cloud of sensors and detecting a variation in its reflectance.

摘要： To transfer a fluid at high service temperature and pressure without the limitations of rigid tubing, a flexible tube is provided with a plurality of generally concentric tubular layers for transferring fluids. The innermost layers define a fluid flow path and provide insulation without pressure containment whereas the outermost layers provide fluid containment and resist pressure exerted by the fluid flowing through the tube. By utilizing a plurality of layers of different materials selected to have specific characteristics, the flexible tube operates at a service temperature and pressure providing a high level of energy transfer.
