摘要： A laminated touch switch panel includes a lowermost insulating board having foil contacts on its top surface and a perforated uppermost board having foil contacts on its bottom surface. A perforated insulating spacer sheet has its bottom surface interfacing with the top of the lowermost board and its upper surface interfacing with an intervening flexible perforated membrane. The membrane has foil contacts on its upper surface which are normally closed with respect to the contacts on the bottom of the uppermost board and has contacts on its lower surface which are normally open with respect to the contacts on the lowermost board. Flexing the membrane with a force applied through the uppermost board opens the normally closed contacts and closes the normally open contacts. In one embodiment, contacts are kept normally closed with resilient elements that apply a force on the membrane which is overcome to open the contacts by applying a force through an aperture in the uppermost board.

摘要： A self-aligning mechanism utilizes a flexible shaft affixed at one end to a means for rotating it. The other end of the rod is configured to engage a complementarily-shaped opening in a coupler provided with a funnel-shaped front surface to guide the flexible shaft into engagement. In one embodiment, the coupler is mounted directly to the shaft of the device to be adjusted. In another embodiment, the coupler is a pulley which drives, by means of a drive belt, a device which is offset in position relative to the flexible shaft. Wire-retaining means are provided to enable the knob and shaft to be easily removed and reinstalled with a minimum of effort and adjustment, even in the presence of misalignment in the X-, Y-, and Z-axis directions.

摘要： A fiber optic illuminating assembly for indirectly and uniformly illuminating the bore of a magnetic resonance (MR) scanner utilizes, in the preferred embodiment, a pair of plastic fiber optic bundles located in the bore behind a deflector element. The fiber optic bundles are made up of many optical fibers cut to different lengths to create point light sources spaced along the length of the bore. A frosted tube surrounds the bundle portion with the point light sources and operates to uniformly diffuse the light. The input ends of the fiber optic bundles are illuminated through an infrared mirror by a non-magnetic quartz-halogen light source operated from a direct current power supply to prolong filament life.

摘要： A printed wire board has lamp socket holes and switch contact pairs adjacent the holes on the top surface of the board and lamp socket contacts adjacent the holes on its bottom surface. An insulating spacer sheet is adhered to the board and has apertures which are congruent with the switch contact pairs. A membrane, adhered to the top surface of the spacer, has lamp holes and short circuiting contacts on its bottom surface for being flexed through the apertures to bridge gaps between the contact pairs on the board. An apertured rigid plate is superposed over and spaced from the membrane. Combination light channel and switch operating plunger elements fit in the plate apertures and contact the membrane. A film on which switch operating touch zones are delineated is adhered to the plate.

摘要： An electronic circuit module includes a smaller than normal size printed wire board and an adaptor plate to fit the printed wire board into a slot of a rack made for normal size modules. A diverter fixed to the adaptor plate funnels cooling air over the adaptor plate to the printed wire board and a cover contains the air flow next to the adaptor plate and printed wire board. A cover is provided for blocking off empty slots of the rack from air flow and a dummy module is positioned to separate modules from any adjacent empty space so as to assure and adequate supply of cooling air to the electronic circuit components of the modules.

摘要： An X-ray table having an elevator mounted on a base for vertical movement, an intermediate support mounted on the elevator for moving longitudinally, and a carriage with a patient cradle on it for moving longitudinally on the support. A pair of gas springs mounted at the forward end of the table provides a constant upward force to compensate for weight of the elevator and the cantilevered load which is exerted as the patient cradle is extended in the longitudinal direction. There are individual servomotors for driving the support and the cradle. The intermediate support drive includes a drive bar and switch assemblies for sensing any force of more than 25 lbs., for example, exerted on the patient or patient cradle and for disengaging the servodrives in response thereto. The cradle drive incorporates a zero-backlash longitudinal friction drive which includes a harmonic drive unit to achieve accurate positioning of the patient. An encoder is driven by a closed-loop cable attached to the patient cradle to accurately indicate its position and speed even though there is a two-stage drive.
摘要翻译：具有安装在用于垂直运动的基座上的电梯的X射线台，安装在电梯上纵向移动的中间支架，以及具有用于在支架上纵向移动的患者支架的滑架。安装在桌子前端的一对气弹簧提供恒定的向上的力，以补偿当患者支架在纵向方向上延伸时施加的电梯和悬臂负载的重量。有单独的伺服电机驱动支架和摇篮。中间支撑驱动器包括驱动杆和开关组件，用于感测例如施加在患者或患者支架上的任何超过25磅的力，并响应于此而使伺服驱动器脱离。托架驱动器包含零间隙纵向摩擦驱动器，其包括谐波驱动单元以实现患者的准确定位。编码器由连接到病人支架的闭环电缆驱动，即使有两级驱动，即可准确地指示其位置和速度。

摘要： Movement control of an L/U arm combination of a medical diagnostic apparatus is maintained by the use of a single handle mounted on the patient table and provision is made for temporarily removing the handle for sterilization and for easily replacing the handle for subsequent use. The handle can be operated by a single hand of an operator to selectively rotate either or both of the L/U elements in either direction on their axes or to move the patient table, longitudinally or laterally, to a desired position. An enabling lever is also provided on the handle such that no movement of the components can occur until the enabling lever has been depressed as by the operators grasping the control handle.
摘要翻译：通过使用安装在患者台上的单个手柄来维持医疗诊断装置的L / U组合的移动控制，并且提供临时移除用于灭菌的手柄并且容易地更换手柄以供随后使用。手柄可以由操作者的单手操作，以选择性地在它们的轴线上沿任一方向旋转L / U元件中的一个或两个，或者将患者台沿纵向或横向移动到期望的位置。在手柄上还设置有使能杆，使得不能像抓握控制手柄的操作者一样按压使能杆。
