  • Patent number: 9945485
    Abstract: A seal assembly includes a seal body having a space formed therein; a seal carrier held within the space, the seal carrier being selectively positionable between a sealing position and a rotation position by moving along a carrying path; at least one seal carried by the seal carrier; and a hermetic seal held within the space out of the carrying path of the seal carrier, the hermetic seal being configured to be abraded away by a rotating element that the hermetic seal is pressing against.

  • Patent number: 8502679
    Abstract: A non-invasive motion and respiration monitor receives impulses from a subject's movement, heartbeat, and respiration. The raw signal is biased and digitized, and a signal processor applies a Fast Fourier Transform to the signal. The transformed signal is filtered to isolate the component representing heart rate from the component representing respiration. An Inverse Fast Fourier Transform is then applied to the component signals, which are sent to a processor. The processor is programmed to detect irregularities in the respiration and heart rate. If severe irregularities or complete cessation is detected in either signal, a mechanical stimulator is actuated to try to stimulate the subject, and an alarm is sounded to alert a caregiver such as a parent or nurse.

  • Patent number: 8087437
    Abstract: A router includes a base, a motor housing supported by the base for movement along a first axis, and an adjustment mechanism having a shaft, with a thread portion, connected to the motor housing for rotation about a second axis. The adjustment mechanism also includes a unitarily formed lock mechanism supported by the base. The lock mechanism includes a thread-engaging member that, when engaged with the thread portion, causes small changes to the position of the housing relative to the base in response to rotation of the shaft. The lock mechanism is movable between an engaged position, in which the thread-engaging member engages the thread portion, and a disengaged position, in which the thread-engaging member disengages the thread portion and the housing is freely movable relative to the base to provide course adjustment of the position of the housing relative to the base.

  • Patent number: 8065911
    Abstract: A method and apparatus for assessing the tread on a vehicle tyre, measuring tyre pressure and calculating other parameters such as vehicle weight. The vehicle is driven in a longitudinal direction so that the tyre passes over a first lateral sensor (6) that extends across the footprint of the tyre, the first sensor comprising an array of individual force sensing elements (11), which provide outputs indicative of tyre pressure at points across the footprint of the tyre. The sensing elements are sampled at intervals as the tyre moves over them, so as to build up data relating to the entire footprint of the tyre. The sensing elements are of relatively high resolution to detect areas within the tyre footprint where there is tread cut into the tyre, so that the extent of tread coverage can be assessed. Tyre pressure is also determined. The tyre then passes over a series of second lateral sensors (7) spaced at intervals to assess the tyre around its circumference.

  • Patent number: 7677280
    Abstract: A power tool, such as, for example a router. In some aspects, a router includes a base, a motor housing supported by the base, a motor supported by the motor housing, and a hand grip forming at least a portion of one of the base and the housing and being contoured to fit a hand of an operator. The one of the base and the housing may be grasped by the operator when the operator grasps the hand grip to control movement of the router on the work piece surface. In other aspects, a router includes a base, a motor housing supported by and movable relative to the base, and a motor supported by the motor housing. The base is contoured to fit a hand of an operator and includes at least one of a slot or a ridge to provide improved gripping for an operator.

  • Patent number: 7669620
    Abstract: A router includes a base for supporting the router on a work piece surface, a motor housing coupled to the base for movement along a first axis relative to the base, a motor supported by the housing and operable to drive a tool element, and a cantilevered shaft rotatable about a second axis and oriented substantially parallel with the first axis and offset from the first axis. The shaft includes a first end supported by the motor housing, a second end, and a threaded portion between the first and second ends. The threaded portion is engaged with the base. Rotation of the shaft about the second axis causes movement of the housing relative to the base along the first axis.

  • Patent number: 7637294
    Abstract: A router includes a base and a motor housing supported by the base and movable relative to the base. One of the base and the motor housing defines a depth adjustment column having an open end. The router also includes a motor supported by the motor housing and operable to drive a tool element, a depth adjustment mechanism at least partially positioned in the depth adjustment column and being operable to adjust the cutting depth of the tool element, and a flexible shield connectable to the base in a position to cover the open end and to allow access to the depth adjustment mechanism through the open end.

  • Publication number: 20070191686
    Abstract: A surgical clamp includes a support frame clamp member, a retraction shaft clamp member and a handle linked to the support frame clamp member and the retraction shaft clamp member for moving the clamp members between loosened and tightened positions. The handle includes a cam, and the handle/cam is unitarily formed by metal injection molding. The handle includes relatively uniform thickness throughout to better accept the shrinkage induced by the metal injection molding process. The base used for a bottom position of the cam is adjustable and spring loaded, to better support a wider range of manufacturing tolerances on the cam as well as the other components of the clamp without over stressing the metal injection molded handle during use. The handle includes a gripping portion with a planar portion inducing alignment of the clamping force as desired for best operation of the clamp.
