The stage apparatus comprises: a substage that, in synchrony with the movement of the first movable body, moves in the first direction with respect to the movement surface; a first measuring apparatus, at least part of which is provided to the substage, that detects information related to the relative position between the substage and the movement surface in the first direction; and a second measuring apparatus at least part of which is provided to the substage, that detects information related to the relative position between the substage and the first movable body in a second direction, which are substantially orthogonal to the first direction and follow along the movement surface.

A quilting apparatus for enabling a user to freely move a stack of fabric layers across a planar bed relative to an actuatable stitch head. The apparatus includes a motion detector which detects the movement of the stack and controls the actuation of the stitch head. Consequently, the apparatus functions to synchronize the delivery of stitch strokes by the head with the manually controlled movement of the quilt material stack. This frees the user to move the stack over a wide range of speeds, to start or stop movement at will, and to guide the stack in any direction across the planar bed.

In a method for generating pulse edges, assigned synchronously to the movement of a mechanical part, a magnetic field is generated. At least two measuring signals phase-shifted to one another for the magnetic field are detected. The magnetic field is changed as a function of the movement of the mechanical part in such a way that the measuring signals are modulated. A first measuring signal is compared with at least one first reference value. A second measuring signal is compared with at least one second reference value and/or the value of the first measuring signal is compared with the value of the second measuring signal. When at least one of these comparisons produces an agreement or the result of the relevant comparison changes its sign, a pulse edge is generated.

A method for dynamically determining a motion control profile used in controlling motion of an axis of an overhead transport motor so as to be synchronized to the motion of a collating transport motor of an insertion engine used to insert a collation into an envelope when the collating transport motor causes a collating pusher to handoff the collation to an overhead pusher being driven by the overhead transport motor. The motion profile consists of a finite number of segments and repeats after the finite number of segments, the finite number of segments constituting a cycle. The method includes the steps of: electronically gearing the overhead transport motor to the collating transport motor from the beginning of a cycle until handoff; based on position information provided by a sensor, determining whether the collating transport is decelerating between handoff and insertion; and using either forward integration or electronic gearing of the overhead transport motor to the collating transport motor up until the collating transport motor is first determined to be decelerating between handoff and insertion, and using forward integration when the collating transport motor is first determined to be decelerating between handoff and insertion and continuing the forward integration until insertion. In some applications, the forward integration is used when the collating transport motor is first determined to be decelerating between handoff and insertion and continuing the forward integration until the end of the cycle.

An X-ray apparatus for digital radiography has a rotating arm where the X-ray source and X-ray sensor cassette are oppositely mounted. The source has a primary collimator to adjust the X-ray beam size according to the selected imaging modality. The sensor cassette encloses a first X-ray detector for a first imaging mode, while a second X-ray detector usable for a second imaging mode is detachably mounted on the external side of the sensor cassette. The sensor cassette accommodates a second collimator to create a fan shaped X-ray beam for a third imaging modality. The sensor cassette has a linear motorized movement which is used for: aligning the X-ray beam with respect to the first and second detector; positioning the first detector in the first imaging mode to achieve an extended view; and scanning movement during the third imaging modality synchronized with the horizontal movement of a third X-ray detector.

An exemplary method includes receiving a measurement corresponding to a particle motion in water surrounding an ROV and synchronizing motion of a docking station with a motion of the ROV based at least in part on the measurement corresponding to the particle motion.

Embodiments of the invention provide for a motion-synchronized virtual reality experience. In particular, in some embodiments, the invention includes a motion platform to impart a shared motion experience to a plurality of passengers, individual head-mounted displays providing for personalized viewpoints, and a variety of immersion-enhancements. A common ride model to controls the motion platform in order to simulate a ride for a plurality of passengers. The passengers' virtual-reality headsets depict the progress of the ride through the virtual-reality world. These headsets track the individual passenger's head or gaze to allow the user to adjust their angle of view in the virtual world simply by looking around. As such, different passengers can be looking in different directions simultaneously, allowing a much greater immersion than the single fixed perspective of prior ride simulations.
