    • A flexion gap instrument is configured to mate with a ligament tensioning tool, such as known distraction devices and pivoting knee balancers. The instrument facilitates making A/P resections in the femur for placement of a femoral prosthesis component to maintain an optimum symmetric flexion gap, which will avoid the risk of medial or lateral laxity in flexion, instability of articulating component dislocation. The instrument includes a base that is configured to sit within the ligament tensioning device, and a vertically extending upstanding portion that is configured to mate with a cutting block or other knee arthroplasty instrument that must be positioned relative to the distal end of the femur. The upstanding portion includes a measurement plate that bears a scale indicating a flexion gap distance. The scale can be used to orient and align the cutting block in its proper position relative to the distal end of the femur, and to orient the cutting block parallel with the tibial plateau with the ligaments properly and equally tensed. In certain embodiments, a leaf spring can be incorporated into the upstanding portion to help support the cutting block and provide a mechanism for temporarily positioning the cutting block on the flexion gap instrument without the need for additional or supplemental locks.
    • 屈曲间隙仪器构造成与韧带张紧工具(例如已知的牵引装置和枢转膝盖平衡器)配合。 该仪器有助于在股骨中进行A / P切除,以放置股骨假体部件以保持最佳对称屈曲间隙,从而避免屈曲内侧或侧向松弛的风险,关节部位脱位的不稳定性。 该仪器包括构造成位于韧带张紧装置内的基部,以及垂直延伸的直立部分,其构造成与必须相对于股骨的远端定位的切割块或其他膝关节置换器械配合。 直立部分包括测量板,其具有指示屈曲间隙距离的刻度。 标尺可用于将切割块定向和对准相对于股骨远端的适当位置,并且使切割块与胫骨平台平行,使韧带适当地等张紧。 在某些实施例中,板簧可以结合到直立部分中以帮助支撑切割块并且提供用于将切割块临时定位在屈曲间隙仪器上的机构,而不需要额外的或补充的锁定。

    • Mobile communication apparatus for use on a vehicle for receiving and transmitting a signal has a transmit/display terminal which is disabled when vehicle motion is permitted. More specifically, a transmitted signal is received, processed and supplied to the display terminal only if a sensor device indicates that vehicle motion is inhibited. If, however, the sensor device indicates that vehicle motion is permitted, the display terminal is disabled and an audible or other signal is generated to announce reception of the signal. Upon hearing the audible signal, the driver of the vehicle may park the vehicle at a convenient location, at which time the processed signal is displayed. Similarly, a unit for transmitting driver initiated signals is inhibited if the sensor device indicates that vehicle motion is permitted, and is enabled if the sensor device indicates that vehicle motion is inhibited.
    • 用于在车辆上接收和发送信号的移动通信装置具有当允许车辆运动时禁用的发送/显示终端。 更具体地,仅当传感器装置指示车辆运动被禁止时,发送信号被接收,处理并提供给显示终端。 然而,如果传感器装置指示允许车辆运动,则显示终端被禁用,并且产生可听或其他信号以宣布信号的接收。 在听到可听见的信号时,车辆的驾驶员可以将车辆停放在方便的位置,此时显示经处理的信号。 类似地,如果传感器装置指示允许车辆运动,则禁止用于发送驾驶员发起的信号的单元,并且如果传感器装置指示车辆运动被禁止,则其被使能。

    • A protection stand comprises a planar surface having first and second sides. The first side of the planar surface comprises a plurality of conical stands that converge away from the planar surface. The second side comprises first and second layers, wherein the first layer is positioned between the planar surface and the second layer and comprises an adaptable cushion for conforming to the surface area of the object resting on the protection stand. The second layer comprises an assembly side and an attachment side, both of such sides comprising an adhesive bond for securing the assembly side to the first layer and the attachment side to the cross-sectional surface of the object resting on the protection stand.

    • Method and apparatus for testing of LCD cells is disclosed. An LCD cell under test (14, 30) may be mounted to translatable table (40) between polarization state generator (10) and polarization state analyzer (16). For each location on cell (14, 30) to be tested, a variety of known polarization states (22) are launched through LCD cell (14, 30) and detected by polarization state analyzer (16). Electrical signals representative of polarization states are acquired by computer (18). Within computer (18), a model (58, 60) of polarization properties of LCD cell (14, 30) is developed based on estimations of what physical parameters of LCD cell (14, 30) are believed to be. RMS differences between simulated polarization properties and measured polarization properties are minimized by iteratively refining (60) modeled physical cell properties, at which point cell thickness and other physical parameters of the LCD cell may be deduced.
