摘要： An apparatus and methods for analyzing feet which utilize matrixes of pressures sensors and optical sensors connected to a controller and a monitor. An apparatus of the invention includes a housing which houses a controller and a monitor and defines left and right foot wells for receiving left and right feet, respectively. The floor of each foot well includes a pressure pad assembly which includes a matrix of pressure sensor contacts covered by a variably resistive pressure pad to form pressure sensor matrixes. A digital signal processor normalizes and smoothes the pressure data for display on the monitor. Infrared LED's and phototransistors are located around the perimeter of each foot well and are utilized to measure the length, width, and heights of a foot. A microprocessor addresses each LED and phototransistor separately. The controller reads data created by the DSP and IR microprocessor, calculates additional data, and displays the resulting data on the monitor. According to one method, the pressure sensors and optical sensors are utilized to determine, among others, foot length, foot width, shoe size, foot volume, foot shape, force distribution, pronation, arch type, and recommended last type. In other methods, the DSP and IR microprocessors provide data which enable the controller to perform calculations and comparisons to display orthotic prescriptions or insole selection information, as well as medical information related to center of pressure and postural sway analysis which is useful in diagnosing and treating a large variety of medical problems.

摘要： A manually or automatically controlled adjusting bed-chair combination for persons suffering limited mobility due to accident, disease, or age who thus require intensive caregiving efforts by others. This portable body supporting device provides a patient with greater mobility and self-care even if he/she is confined therein for weeks, months, or longer. The bed-chair includes an upper frame for supporting the invalid's body in a large number of postures ranging from side, supine, sitting, reclining or standing. In turn, this upper frame is articulated by lower supporting frames powered by linear actuators, or the equivalent, and controlled by the patient control or the caregiver's override and automatically preset control to provide a timed regimen of turning or tilting according to the occupant's needs. Whether in bed or chair mode, the support frame consists of an upper body, middle and leg-foot segment. The mid-section provides a base to which the other two sections are pivotally mounted. Turning the middle section up to 20.degree. right or left relieves the local pressure on skin and other tissue yielding comfort and avoiding ulceration, cramping and discomfort. The optional accessories further increase the freedom of choice of more positions, actions, and controls, even to sensing difficulty and aiding excretion along with the option of using vibration and other therapeutic stimulations. The bed-chair's diverse positions enable easier entrance and exit. Ready disassembly into three or more sections facilitates transport. A mattress with special foam distributes the body weight over maximum area while cervical and lumbar supports plus adjustable edge tubes give security and comfort choice to abet healing.
摘要翻译：手动或自动控制的调整床椅组合，适用于由于意外，疾病或年龄而容易受限的人员，因此需要他人进行深入的照顾。这种便携式身体支撑装置为患者提供更大的流动性和自我照顾，即使他/她被限制在几个月，几个月或更长时间。床椅包括一个上部框架，用于支撑从身体，仰卧，坐着，斜倚或站立的大量姿势的无效身体。反过来，该上框架通过由线性致动器供电的下支撑框架或相当的，由患者控制或照顾者超驰控制，并且根据乘客的需要自动预设控制以提供转向或倾斜的定时方案。无论是卧床还是椅子，支架由上身，中脚和腿脚组成。中间部分提供了另一个两个部分枢轴安装的基座。将中间部分向右或向右转动20度可缓解局部对皮肤和其他组织的压力，从而舒适，避免溃疡，痉挛和不适。可选附件进一步增加了更多位置，动作和控制的选择的自由度，甚至可以检测难度和辅助排泄以及使用振动和其他治疗刺激的选择。床椅的不同位置使得入口和出口更加方便。准备拆卸成三个或更多部分便于运输。具有特殊泡沫的床垫将体重分布在最大面积上，而颈部和腰部支撑加上可调节的边缘管，可以提供安全和舒适的选择来治疗。
