    • A method and apparatus for measuring feet for fitting shoes which utilizes 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 smooths 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. 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. Such determinations, along with intended use information obtained from the customer, are compared to a database of available shoes to determine recommended best fits for each customer. Such data can also be stored or transferred to an external system for storage with reference to each particular customer.
    • 一种用于测量用于装配鞋的脚的方法和装置,其利用连接到控制器和监视器的压力传感器和光学传感器的矩阵。 本发明的装置包括容纳控制器和监视器并且分别定义用于接收左脚和右脚的左右脚孔的壳体。 每个脚井的底板包括压力垫组件,其包括由可变阻力压力垫覆盖的压力传感器触点的矩阵,以形成压力传感器矩阵。 数字信号处理器将压力数据归一化并平滑显示在显示器上。 红外LED和光电晶体管位于每个脚井的周边周围,并用于测量脚的长度,宽度和高度。 微处理器分别对每个LED和光电晶体管进行寻址。 控制器读取由DSP和IR微处理器创建的数据,计算附加数据,并在监视器上显示结果数据。 压力传感器和光学传感器用于确定脚长度,脚宽,鞋尺寸,足部体积,脚形,力分布,旋前,弓形和推荐的最后类型。 将这样的确定以及从客户获得的预期用途信息与可用鞋的数据库进行比较,以确定每个客户的推荐最佳配合。 这些数据也可以存储或传输到外部系统,以便参考每个特定客户进行存储。

    • A number of arrangements for protecting an electrical circuit from an electrical overcurrent are disclosed. In the arrangements the base or gate of a switching transistor (4, 101, 161, 222, 401) is held in a voltage divider, one arm of which comprises a control transistor (6, 102, 162, 222, 404) whose base or gate is itself held in a voltage divider. When an overcurrent is experienced the control transistor switches on causing the switching transistor to turn off. The arrangement may include a shunt switching circuit to shunt the overcurrent across the load. It may include a resetting circuit that will attempt to reset the switching circuit after the overcurrent has been experienced. In one embodiment the arrangement includes means such as a battery, dc--dc voltage converter or Seebeck device in order to reduce or eliminate any initial voltage drop across the switching circuit.
    • 公开了一种用于保护电路免受电过电流的布置。 在这种布置中,开关晶体管(4,101,161,222,401)的基极或栅极保持在分压器中,其一个臂包括控制晶体管(6,102,162,222,404),其基极 或门本身保持在分压器中。 当发生过电流时,控制晶体管导通,导致开关晶体管截止。 该装置可以包括分流开关电路,以分流跨过负载的过电流。 它可能包括在经历过电流之后尝试复位开关电路的复位电路。 在一个实施例中,该装置包括诸如电池,dc-dc电压转换器或Seebeck装置的装置,以便减少或消除开关电路两端的任何初始电压降。
