Abstract: A display apparatus includes an image source that scans about two axes. To offset motion about a first of the axes during sweeps about the second axis, the apparatus includes a structure to produce offsetting motion about the first axis at a scanning rate equal to the twice-scanning rate about the second axis. The offsetting scan can be a ramp or other motion. In one embodiment, the offsetting motion is a resonant sinusoid. The offsetting motion may be produced by an auxiliary scanner such as a mechanical scanner, a piezoelectric scanner, a MEMs scanner or other scanner. Because the offsetting motion is very small, the auxiliary scanner can function with a very small scan angle.

Abstract: A linear motion micropositioning device employs a housing containing fixed, electrically excited stators. A rotating permanent magnet rotor is directly attached to a spindle of a precision lead screw. The stators are provided with sufficient axial depth to permit the rotor to rotate and reciprocate axially while under continuous magnetic influence of the stators.

Abstract: An orthogonal motion stage provides Z axis motion, along an optical axis independently of translational motion in an orthogonal, X-Y axis reference plane. Conversely, motion in the X-Y reference plane does not induce unwanted motion in the Z axis. Straight line mechanisms interconnect the Z axis carrier to a base plate. Flexible connections are used in the straight line mechanisms to ensure accurate orthogonal motion.

Abstract: In a capacitive-type linear displacement measuring device, a pick-off body is resiliently biased into sliding contact with a scale. The pick-off body is supported by a flat spring and resiliently biased towards the scale by a leaf spring. The front surface of the scale slides in abutting contact with the front surface of the pick-off body. The flat spring restrains non-axial movement of the pick-off body but permits movement normal to the axial movement so that the pick-off body accurately tracks and remains in abutting contact with the scale as it slides in an axial direction. Changes in capacitance caused by axial displacement of the scale are accurately sensed and changes in capacitance caused by non-axial motion are avoided.

Abstract: A spindle for a linear distance measuring member is described herein. A linear gauge is provided with a hollow spindle having a flexible rod therein. The flexible rod is rigidly coupled at one end to the spindle, and at the other end thereof to the measuring member. Axial motion of the spindle is transferred directly to axial motion of the measuring member, because the axial movement of the rod exactly corresponds to axial movement of the spindle. If the spindle undergoes nonaxial movement, such as by tilting, the flexible rod within the spindle bends to accommodate for the change in length to the spindle. The use of a hollow spindle with a flexible rod therein effectively decouples nonaxial movement of a spindle from axial movement of a measuring member. A device made according to the principles taught herein may be used in any linear measuring system which transfers axial motion of one member to axial motion of a measuring member, to decouple laterial motion between the two for minimizing the errors.

Abstract: The article includes a first vial (12) which is positioned within a second larger vial (32). The first vial (12) separately contains a first fluid, such as a first calibrating fluid, and the second vial (32) contains a second fluid, such as a second calibrating fluid. A stopper (18) seals the first vial (12) and holds a sensing portion (21) of the sensor in the first vial (12). The first vial (12) is released from the second vial (32) by activating a plunger (36).An encapsulation package (50) having first and second elements (51, 52) maintains the chemical sensor and a calibrating article or vessel in a sterile condition. The package includes a first cavity (54) which receives the calibrating vessel, the sensing portion of the sensor and a substantial portion of the sensor cable, and a second cavity (56) which receives the sensor connector. A passageway (58) connecting the two cavities (54, 56) is adapted to receive a portion of the sensor cable.

Abstract: A surgical scalpel for use in ophthalmic and other forms of surgery having a blade that can be adjustably extended beyond a foot. The scalpel also includes an indicator for showing the length of the blade that is exposed beyond the foot. The indicator can be calibrated to compensate for variations in blade length and other manufacturing tolerances.

Abstract: An intraocular lens four point contact haptics with an asymmetrical cross section. The ends of each of the haptics are contiguously juxtaposed and inserted in a common bore in the periphery of the optic. The legs of each of the haptics spiral outwardly in juxtaposed relationship, separate and extend away from each other to form eye contacting heel and toe portions residing on opposing sides of the inferior-superior axis of the lens. When two such haptics are employed, a wide haptic compression range can be achieved with little differential in compression force.
