A leveling system for a workpiece comprises a vise for holding the workpiece and a multimember support structure for positioning the vise. The multimember support structure comprises at least two joints and provides at least five independent degrees of freedom in angular motion for positioning the vise and leveling the workpiece.

This optical encoder includes a light emitting section and a plurality of light receiving elements placed so as to be aligned in one direction in an area where a light beam from the light emitting section may reach. A moving object includes a light-ON section, a light-OFF section and an index pattern section. The light receiving element outputs a first light receiving signal when the light-ON section and the light-OFF section of the moving object pass through a predetermined position corresponding to the light receiving element. The light receiving element outputs a second light receiving signal when the index pattern section of the moving object passes through a predetermined position corresponding to the light receiving element. The output section outputs an incremental channel signal indicating movement information of the moving object based on the first light receiving signal while outputting an index channel signal indicating reference position of the moving object based on the second light receiving signal. The incremental channel signal and the index channel signal are out of phase with each other.

A beam profile measurement detector is a tool to efficiently verify dose distributions created with active methods of a clinical proton beam delivery. A Multi-Pad Ionization Chamber (MPIC) has 128 ionization chambers arranged in one plane and measure lateral profiles in fields up to 38 cm in diameter. The MPIC pads have a 5 mm pitch for fields up to 20 cm in diameter and a 7 mm pitch for larger fields, providing an accuracy of field size determination of about 0.5 mm. The Multi-Layer Ionization Chamber (MLIC) detector contains 122 small-volume ionization chambers stacked at a 1.82 mm step (water-equivalent) for depth-dose profile measurements. The MLIC detector can measure profiles up to 20 cm in depth, and determine the 80% distal dose fall-off with about 0.1 mm precision. Both detectors can be connected to the same set of electronics modules, which form the detectors' data acquisition system. The detectors operate in proton fields produced with active methods of beam delivery such as uniform scanning and energy stacking. The MPIC and MLIC detectors can be used for dosimetric characterization of clinical proton fields.

A microfluidic sensor formed by stacking a plurality of substantially non-electrically conductive layers, typically formed from thin polymer films. Certain layers may carry patterned electrodes that are arranged to permit their connection to an electrical interrogation circuit. Electrodes may be disposed in a 3-dimensional array in the sensor. A fluid path through the sensor includes an orifice sized to promote single-file travel of particles. The orifice may be defined by a tunnel passing through at least one layer. Particles entrained in an electrolytic carrier fluid may be detected, or otherwise characterized, by interrogation circuitry connected to certain embodiments of the sensor. Sensors generally include portions of a fluid path disposed parallel to the layers. Sensors may operate under the Coulter principle, and / or Stokes' shift phenomena. In certain embodiments, the sensor may be carried by a cartridge, which is adapted to couple with an interrogation platform. In any case, coupling desirably places the sensor in-circuit with operable interrogation structure, as well as with a fluid-flow control device. Structure included in a cartridge may provide fluid sample loading, routing, and storage capabilities.

Integrated closed-loop real-time limb neuro-prosthetic system comprising an artificial limb, a microprocessor, sensors, a signal conditioner, a stimulator, at least one EMG electrode and at least one sensory feedback electrode, characterized by the fact that said sensory feedback electrode is all intraneural electrode which is adapted to be implanted in an intact and healthy portion of a nerve.

An LSI package having an optical interface is mounted on a surface of a photoelectric wiring board. The photoelectric wiring board and the optical interface are optically connected with sufficient precision. A wiring board side guide member including socket pins and guide pins is soldered and fixed onto the photoelectric wiring board including an optical transmission line, a guide pin, and a mirror. An optical interface side guide member having a fitting hole is glued to the optical interface. The optical interface is mounted on an interposer of the LSI package. The guide pin of the photoelectric wiring board is fitted into the fitting hole formed through the interposer. The guide pin of the guide member is fitted into the fitting hole of the guide member. As a result, position alignment between the optical interface and the photoelectric wiring board is conducted with high precision.
