摘要： A continuous optical calibration system for a galvanometer scanner. The system maintains one or more fiducial position references in each axis, independent of the normal position detector circuit. An optical reference position monitor circuit triggers a calibration signal when load position coincides with a reference position, whereupon the measured position of the position detector and then current look up table is compared to the known reference position, and an error correction is generated and applied to the look up table. The optical monitor circuit includes a rotor rigidly attached to the load shaft so as to rotate between a light emitter and detector. A thin slit in the rotor permits passage of a highly collimated light beam to the detector only when the slit is aligned between the emitter and detector, which occurs only when the load is at or passing through the reference position.

摘要： A heat insulating paper cup having an improved seal. The cup can include a body member having an inside surface and an outside surface, and a bottom panel member having a upper surface and a bottom surface. The body member is coated (or in some instances partially coated) on its outside surface with a foamed low density polyethylene, and on its inside surface with an unfoamed modified low density polyethylene. The bottom panel member is coated on its upper surface with a foamed or an unfoamed low density polyethylene or foamed or unfoamed modified low density polyethylene. The body member and bottom panel member are oriented and joined to form a heat seal at an interface between a portion of the unfoamed modified low density polyethylene coated on the inside surface of the body member and a portion of unfoamed low density polyethylene or unfoamed modified low density polyethylene coated on the upper surface of the bottom panel member.

摘要： A galvanometer unit includes a limited-rotation motor with a load element such as a mirror attached to a shaft extending from the motor. In a servo loop that controls the angular position of the mirror, a position-sensor attached to the shaft provides position feedback information. The sensor includes a rotor which is positioned at the null point of the fundamental torsional resonance mode of the rotating system, thereby essentially eliminating feedback components resulting from the resonance.

摘要： A method for filling a liquid filled container includes the steps of providing a container, placing a capsule defining a cavity in the container, filling the container with a liquid, and allowing a gaseous exchange between the liquid and the cavity to provide a benefit to one of the capsule and the liquid. The invention also includes a method for providing a retrievable payload in a liquid filled container that includes the steps of providing a capsule in a liquid filled container wherein the capsule has a cavity and is associated with the payload. The method further includes the step of pressurizing the cavity. The present invention also includes a capsule having a body defining a cavity and an opening communicating with the cavity, a payload disposed in the cavity, sealing means for sealing the cavity which contains gas at a first pressure greater than atmospheric pressure when the cavity is sealed, and vent means for selectively venting the pressurized gas from the cavity. Other embodiments of the capsule include a cap engageable with the body at the opening and movable between a sealed position wherein the cap engages the body to seal the cavity and an open position providing access to the cavity. Connecting means and presentation means may also be included with the capsule for coupling the cap to the body when the cap is removed from the opening and for moving the payload toward the opening when the cap is in the open position, respectively.

摘要： An adjustable masking mechanism for use in connection with the exposure of a sample to a beam of analytical radiation and a beam of viewing radiation that facilitates aligning the movable elements of the mask with the edges of the sample. Whereas the prior art mechanisms utilize materials that are opaque to both the analytical radiation and the viewing radiation, the present invention uses one or more movable elements that are substantially opaque to the analytical radiation and at least partially transmissive to at least a portion of the spectral range of the viewing radiation.

摘要： The biomedical pump includes a housing with an internal pump chamber defined by a first rigid concave wall formed by the pump body, and an opposed flexible wall defined by a diaphragm incorporating a heat responsive disc for a thermal-responsive pumping movement between a first position overlying and conforming to the body defined first wall and a second position outwardly spaced therefrom. An inlet passageway and an outlet passageway each communicate with the interior of the chamber through the pump body. Each passageway incorporates a one-way check valve for a directional control of the fluid flow in response to the heat induced diaphragm movement.
