Apparatus and method for rotary die x, y, and theta registration

A rotary die apparatus and method for three-axes registration error correction. The rotary die apparatus includes a rotary die for applying patterns to a strip of material, a sensor for sensing fiducials on the strip of material, actuators to adjust the rotary die, and a control system. ... Preco Inc

Method and apparatus for producing information indicative of cardiac malfunctions

An apparatus for producing information indicative of cardiac malfunctions, for example atrial fibrillation, includes a processing system for processing an analysis signal produced by a sensor system responsive to motion including cardiovascular motion. The processing system is configured to form a first indicator quantity indicating degree of concentration of the autocorrelation of the analysis signal to a point corresponding to zero time difference between analysis signal samples whose mutual correlation is expressed by the autocorrelation and a second indicator quantity indicating the spectral entropy of the analysis signal. ... Preco Inc

Treating postoperative nausea and vomiting

Methods, compositions, systems, and packaging are disclosed for reducing postoperative nausea and/or vomiting (ponv) in a human patient in need of general anesthesia for surgery. Such methods may include scheduling a surgery for the human patient, and administering to the patient one or more series of prescribed medicines for at least three successive days during a regimen immediately preceding general anesthesia. ... Preco Inc

Under material air purge

An assembly and method of reducing discoloration of a foam material resulting from laser processing the material comprising an assembly configured for positioning below the material being processed and for directing air into open cells of the open-cell foam material to pressurize the material during laser processing. The assembly comprises an air delivery mechanism comprising one or more apertures for an air chamber positioned directly below the material travel path. ... Preco Inc

Galvo cooling air bypass to reduce contamination

A system and method of cooling and purging a laser processing system comprising at least one galvo system for directing at least one laser beam to a work piece and a protection window mounting plate comprising at least one protection window secured in a corresponding cavity of the mounting plate where the plate is configured with at least one air flow passageway in the mounting plate for each protection window such that an airflow used to cool each galvo systems is directed through the mounting plate vis the passageway and further directed past the window cavity to purge the cavity, where the purging air flow is then vented or exhausted from the laser system.. . ... Preco Inc

Variable distance eddy current braking system

An apparatus includes a flywheel, a first pivotable caliper, a first magnet supported by the first caliper opposite the flywheel, a second pivotable caliper and a second magnet supported by the second caliper opposite the flywheel. In one implementation, the apparatus further includes a first cam follower coupled to the first caliper, a second cam follower coupled to the second caliper and at least one cam member including a first cam surface against which the first cam follower moves and a second cam surface against which the second cam follower moves, wherein movement of the at least one cam member pivots the first caliper and the second caliper to move the first magnet and the second magnet relative to the flywheel. ... Preco Inc

Exercise apparatus with eddy current rail

An apparatus and method operably coupled a movable member of an exercise apparatus to a carriage such a movement of the movable member moves the carriage along a rail. A magnetic portion carried by the carriage induces eddy currents in the rail to resist movement of the carriage along the rail to resist movement of the movable member.. ... Preco Inc

Selectable stride elliptical

An exercise apparatus comprises a frame, left and right foot link supporting left and right foot pads. The left and right foot pads synchronously move out of phase through an elliptical path having an adjustable step height. ... Preco Inc

Optic heating compensation in a laser processing system

A laser beam is applied to optics to focus the laser beam into a focal point substantially on a piece of working material. An expected shift in a focal plane due to heating of the optics by the laser beam is determined. ... Preco Inc
