    摘要： A handle having a gripping member. A base can be attached to a guidance device worn by an animal A retractable pulley assembly connects the base to the handle. A braking assembly has a trigger and a braking member. The retractable pulley assembly includes a spool, a wheel, an anchor, and a flexible member having a first end and a second end with the flexible member extending from the base to the handle, around the wheel, and to the anchor and with the flexible member being fixedly attached to the spool at the first end and to the anchor at the second end. The trigger actuates the braking member to frictionally engage the flexible member at an intermediate point between the flexible member first end and the flexible member second end to fix the distance between the handle and the base when the flexible member is pulled taut.

    摘要： Flow through a sleeve is controlled with a housing. A removable frame is positioned within the housing. A removable, tubular rotational mechanism defines a hole for receiving the sleeve therein. A pair of arms are pivotally mounted on the rotational mechanism for squeezing the sleeve. An actuator drives the rotational mechanism to pivot the pair of arms to open and to close the sleeve.

    摘要： Disclosed is a system and method for measuring the position of at least one field producing element (e.g., a magnet) without a direct electrical or physical connection between the field producing element and the sensor(s). In one embodiment, the output from an array of sensors (e.g., Hall Effect sensors) is curve fit using an algorithm having a characteristic bell curve (e.g., curve fit tracking algorithm, center of gravity algorithm, etc.) to determine at least one of an absolute or relative position associated with the field producing element and/or a property associated with the field producing element (e.g., magnetic flux). Another embodiment is directed to detecting errors in one or more of the sensors and excluding the output of the faulty sensors in determining the position associated with the field producing element.

    摘要： A guide for a video pipe inspection system that includes a camera head and a tubular coil spring having a central axis. A guide member with radially extending fins is configured to surround the tubular spring. At least one pin is removably engageable with the guide member and the tubular coil spring to retain the guide member in position with respect to the tubular coil spring. The straight segments of a pair of opposing U-shaped pins can be inserted into grooves in the guide member so that they extend between adjacent coils of the tubular coil spring. In alternate form, the guide member may include an inner capture ring assembly that receives the pins. An outer yoke assembly surrounds, and is freely rotatable about, the inner capture ring assembly and includes a pair of axles for rotatably supporting a pair of wheels that engage an interior wall of the pipe.

    摘要： A fiber optic signal collection system and method for position sensing or sensing other parameters indicated by light distinctive patterns. The system is particularly suitable for use in aircraft flight control. The system includes a set of fiber optic fibers with first and second ends. The first ends are disposed adjacent a light distinctive pattern indicating a particular pattern such as a relative position. A portion of the second ends are positioned adjacent a light source and a portion of the second ends are disposed adjacent a light sensing electrical device such that light from the light source can be conveyed through the fibers, reflected from the light distinctive pattern, and conveyed through the fibers to the light sensing electrical device in order to detect the pattern in the electrical device. By this means the parameter indicated by the light distinctive pattern can be detected, and the right indication of which can be remotely conveyed through the fiber optic fibers to a conveniently located light sensing electrical device. Multiple parameters can be sensed with a single light sensing electrical device by alternate routing of light from different light distinctive patterns indicating different parameters to the light sensing electrical device.
