摘要:
A system of inflatable air cells is constructed and installed in a seat at locations that are strategic to the comfort of the user. The air cells are connected to a pump through a manifold which sequentially connects each cell independently to the pump. The manifold controls the flow of fluid in the air cell distribution system by means of a system of valves and senses the pressure in each cell by means of a transducer. A microcomputer is programmed with data representing a desired comfort level for each of the air cells. By sequentially activating individual manifold valves, a pressure signal from the transducer can be generated for each cell. The pressure signals are received by the microcomputer and are correlated with the predetermined comfort data to generate a control signal which activates the pump. In this manner each of the cells can be individually inflated or deflated to the desired pressure level. By varying the number and location of the cells the system becomes responsive to the localized pressures exerted on the body for a great variety of users.
摘要:
Method and system for the automated assembly of power train components along a plurality of interconnected, closed loops within cells of the system wherein parts and/or subassemblies of the components are assembled on the same assembly pallet on which they were robotically kitted. Along some of the loops, the assembly pallets are automatically transferred from kitting stations to assembly stations and from the assembly stations to an unload station where the components or subassemblies are robotically unloaded. The unloaded assembly pallets are then automatically transferred from the unload station to the kitting stations to repeat the assembly process. A mechanical guided vehicle system (MGVS) asynchronously conveys the assembly pallets along the closed loops which form guide tracks between the different stations. An automated guided vehicle system (AGVS) preferably transports part storage pallets to the system from a receiving area. Automated stacking cranes transfer the part storage pallets to and from predetermined part positions within queuing rack structures adjacent the kitting and assembly stations. The queuing rack structures and the automatic stacking cranes form part of an automated storage and retrieval system (AS/RS) which interconnect the different closed loop guide tracks. The queuing rack structure also stores subassemblies loaded on assembly pallets. Manual kitting and assembly areas are also provided. Fastening robots are provided at fastening stations located along selected ones of the guide tracks. A distributed or hierarchial control system controls each of the elements of the system.

A low energy consumption valve module (16) includes low energy consumption valves (20) having either bimorphs or monomorphs defined by a circular diaphragm (21) carrying one or more piezoelectric discs (22) (23) operative to position a sealing disc (36) for sealing a valve seat (34). In one embodiment the discs are energized across conductive seals (51,52,54,56) and in another embodiment the discs are energized by a pair of flexible conductors (150). A process for making the bimorphs or monomorphs comprises a tape cast process in which ceramic with piezoelectric properties is shaped without machining. A process for making the valve module providing a valve body (200) and valve cover (202) of either laser energy transparent or laser energy absorbent polyimide material that are joined at a line to line contact (210) and sealed upon application of a laser welding beam to the line to line contact between the valve body and the valve cover at the perimeter thereof.

A lumbar support mechanism includes a flexible support member, a spring and a cable assembly. The flexible support member has oppositely disposed first and second ends. The spring has a first end and a second end. The first end of the spring is connected to one of the first end and second ends of the flexible support member. The cable assembly includes a sleeve and a cable slidably disposed therein. The sleeve has a first end connected to the second end of the spring. The cable has a first end connected an other of the first and second ends of the flexible support member.
