Title: Rotation linear grating angle encoder
Inventor: Lin shi-cong
IPC: G01B11/26
Filed: 1998-09-14
Granted: 1999-06-11
Abstract: This invention relates to a rotation linear grating angle encoder, which comprises a laser source, a rotation body, a laser guidance device, and one or two sets of photo detection device; in which the rotation body comprises a linear grating and a rotation axis. Furthermore, a specific included angle exists between the grating normal line and the rotation axis. The engraving direction of the grating is orthogonal to the plane formed by the rotation axis and the grating normal line. When the laser guidance device guides the laser light to the grating in a direction parallel to the rotation axis, a non-zero-step diffraction light will diffract back in a direction opposite to the incident direction. The direction of the diffracted laser light will not change due to the rotation of the rotation body. However, the travel distance of light thereof alters along with a change in the rotation angle. Furthermore, the diffraction light is guided into the photo detection device by the laser guidance device to measure the travel distance of the diffraction light which can be used to estimate the rotation angle of the rotation body.

Title: A suspension system for a pedal-driven vehicle
Inventor: TURNER PAUL H
IPC: F16F9/50
Filed: 1998-12-08
Granted: 2001-06-07
Abstract: A suspension system, particularly for a pedal-driven vehicle, comprising a telescoping strut having first and second telescopingly and coaxially engaged members, and having a damping system comprising a damping fluid, a damping piston connected to a piston rod, an inertia-activated compression fluid flow control mechanism and a pressure-activated compression fluid flow control mechanism disposed in the first telescoping strut. The inertia-activated compression fluid flow control mechanism comprises a valve body biased by a valve spring into a first position over a radial groove formed on the piston so that the valve body prevents fluid flow through an inertia-activated compression fluid flow circuit in response to force inputs imparted to the vehicle frame. The valve spring and valve body are connected to the piston rod which extends into the first telescoping member and is attached to the vehicle wheel, such that the valve body may be moved into a second position permitting fluid flow through the inertia-activated compression fluid flow circuit by force inputs imparted to the vehicle wheel. Because the inertia-activated fluid flow control mechanism is inertia-activated and not pressure-activated, a force impact imparted to the vehicle wheel results an fluid flow through both the pressure-activated and inertia-activated flow circuits, whereas force inputs such as from pedalling, weight shifting and acceleration or deceleration forces do not result in flow through the inertia-activated circuit. The suspension system therefore resists the absorption of pedal drive energy, provides a ride-leveling effect, and provides a broad range over which the damping system may be adjusted.
