Abstract:
Provided herein are devices, systems, and methods for electrically-augmented damping of an actuator and associated devices. In particular, electrically-augmented damping derived from measurement of voltage across an actuator and current flowing through an actuator is provided.
Abstract:
Specified is a measuring arrangement for optical absorption spectroscopy, in which the light used for the measurement is injected into a container with hot gas in coupling elements (21, 22) of several cm in length. Here, light source (16) and photodetector (17) are connected to the coupling elements without air gaps. A heater (24) maintains the temperature of the coupling elements above the surrounding temperature in order to prevent the condensation of various substances.
Abstract:
A calibration system (300) for a detector (328) includes a base member (302), a plurality of radiation sources (304)fixedly attached to the base member, and a positioning mechanism (306) attached to the base member. Each radiation source (394) is maintained at a different temperature and is configured to emit electromagnetic radiation. The positioning mechanism includes a movable member (308) having a single degree of freedom with respect to the base member (302), and a plurality of optical elements arranged (310) on the movable member. Each optical element corresponds (310) to one of the radiation sources (304) and each optical element is configured to at least be movable between a calibration position and a non-calibration position. When the optical element is in the calibration position, the optical element is configured to receive the electromagnetic radiation from its corresponding radiation source and to reflect the electromagnetic radiation to a detector.

Abstract:
An optical scanning or positioning mechanism has a head on which optical components are mounted and an actuator coupled to the head to cause the head to move when the actuator is actuated. There are one or more sets of flexure bearings mounted in the mechanism. The flexure bearings have a restoring torque when moved from a rest position. The bearings are coupled to the head to allow the head to move when actuated by the actuator. One or more magnets are mounted in the mechanism in a location other than in the actuator to compensate for the flexure bearings restoring torque.
