Edward P. Donlon - San Jose CA
Joseph R. Rimsa - Alameda CA
Louis Hlousek - Reno NV

Assignee:

Alara, Inc. - Hayward CA

International Classification:

G01N 2304

US Classification:

250584, 250591

Abstract:

A system is provided for scanning an object, the system comprising: a drive shaft having a proximal portion and a longitudinal axis; a motor including a motor shaft having a rotational axis, the motor serving to rotate the motor shaft about the rotational axis; a flexible joint coupling the drive shaft to the motor shaft by the proximal portion of the drive shaft, the flexible joint having a range of motion which allows the longitudinal axis of the drive shaft to move relative to the rotational axis of the motor shaft; and an object attached to the drive shaft which is movable along the longitudinal axis of the drive shaft in response to the drive shaft being rotated by the motor. This system may be used in a drum scanner system and may be used to read storage layer radiation screens.

Abstract:

A method and a device for detecting an analyte, including a substrate having a chemically selective surface; and a fluidic system disposed on the substrate, the manifold having at least one fluid path in communication with at least a discrete region of the surface, wherein the one fluid path and the discrete region together define a contained sample region on the surface. The fluidic system has a removable portion, wherein the removal of the removable portion of the fluidic system renders the discrete region directly interrogatable by a surface-based analytical tool.

International Classification:

H01J 3150

US Classification:

25023116

Abstract:

An apparatus and method for rotating an optical element, such as a diffraction grating or mirror, utilizes a moving coil actuator and an optical encoder to provide precise element position control. The moving coil actuator, which is coupled to the optical element, is comprised of a coil immersed in a magnetic field created by a pair of magnets. Current flowing in the coil windings causes the coil, and ultimately the optical element, to rotate. An optical encoder monitors the rotation of the element and provides rotation signals representative of the instantaneous element position to an actuator control circuit. The actuator control circuit phase shifts the rotation signals and compares the phase shifted rotation signals to a desired reference signal to generate position and velocity error signals. In a track follow mode, the position error signal is applied to the moving coil actuator via a loop compensator. When the apparatus is operating in an optimal seek mode, a trajectory generator receives the velocity error signals and generates an optimum velocity signal based on a preprogrammed velocity curve.
