    • An exercise treadmill (20) is described having a number of assembly improvements. In one embodiment, a pivot assembly (50) is provided to allow a treadmill deck (32) to deflect during use. The rear pivot assembly includes a pin (56) transversely mounted on the upper surface of a treadmill frame (22). A pivot block (54) is attached to the deck and includes a lower channel (58) that engages the pin. In another embodiment, an adjustable rear foot assembly (70) is provided having a foot (74) that is rotatable within a mounting block (72). The foot is easily accessed through an upper opening (96) in the treadmill. In yet another embodiment, an air dam (100) is provided between a motor compartment (102) and an adjacent endless belt (28). In still another embodiment, a highly elastic drivebelt (120) is used between a motor assembly (104) and a roller assembly (24) that drives the endless belt (28). Lastly, an embodiment is described in which the treadmill frame (22) is assembled using swaged fasteners (38).
    • 描述了具有许多装配改进的运动跑步机(20)。 在一个实施例中,提供枢轴组件(50)以允许跑步机甲板(32)在使用期间偏转。 后枢转组件包括横向安装在跑步机框架(22)的上表面上的销(56)。 枢轴块(54)附接到甲板上并且包括接合销的下通道(58)。 在另一个实施例中,提供了一种可调节后脚组件(70),其具有可在安装块(72)内旋转的脚部(74)。 足部容易通过跑步机中的上部开口(96)进入。 在另一个实施例中,空气坝(100)设置在电动机室(102)和相邻环形带(28)之间。 在另一个实施例中,在马达组件(104)和驱动环形带(28)的滚子组件(24)之间使用高度弹性的驱动带(120)。 最后,描述了一种实施例,其中使用挤压紧固件(38)组装跑步机框架(22)。

    • An avalanche photodiode circuit, comprising an avalanche photodiode typically connected in parallel to a capacitor, in which there is provided a current shunt circuit which activates to shunt current from the avalanche photodiode in response to detecting a decrease in the impedance of the avalanche photodiode, typically measured by determining the slope of the voltage across the avalanche photodiode. By using this circuit, the avalanche photodiode can be protected from sudden increases in incident light level decreasing the impedance of the avalanche photodiode to an extent that the energy such as is stored in the capacitor can damage the structure of the avalanche photodiode.
    • 通常雪崩光电二极管包括通常并联连接到电容器的雪崩光电二极管,其中提供了一个电流分流电路,其响应于检测到雪崩光电二极管的阻抗的降低而激活以分流来自雪崩光电二极管的电流 通过确定雪崩光电二极管两端的电压的斜率来测量。 通过使用该电路,可以防止雪崩光电二极管突然增加入射光级,从而降低雪崩光电二极管的阻抗,使得诸如存储在电容器中的能量可能损坏雪崩光电二极管的结构。

    • An exercise device includes a frame defining a longitudinal axis. A foot link includes a rearward portion that is constrained to move in an orbital path approximately parallel to the longitudinal axis and a forward portion that reciprocally engages the guide track. A swing arm is a pivotally connected to the frame, the swing arm having an upper portion extending above the pivotal connection and a lower portion disposed below the pivotal connection. An engagement mechanism having a first portion coupled to the lower portion and a second portion coupled to the forward portion of the foot link, such that a rearward force applied to the upper portion will produce a force on the forward portion having a downward component. An arm enabling/disabling mechanism is positioned on the elongate swing arm below the pivotal connection. The arm enabling/disabling mechanism can be effectuated by a user without the user interrupting exercise.
    • 锻炼装置包括限定纵向轴线的框架。 脚连杆包括被限制为在大致平行于纵向轴线的轨道中移动的向后部分和与引导轨道往复接合的前部。 摆臂枢转地连接到框架,摆臂具有在枢转连接件上方延伸的上部和设置在枢转连接下方的下部。 接合机构具有联接到下部的第一部分和联接到脚连杆的前部的第二部分,使得施加到上部的向后的力将在具有向下部件的前部上产生力。 手臂启用/禁用机构位于枢转连接下方的细长摆臂上。 手臂启用/禁用机制可以由用户实现,而不需要用户中断运动。
