Abstract:
Exemplary embodiments enable an enhanced direct-viewing optical device to include customized adjustments that accommodate various optical aberrations of a current user. Customized optical elements associated with an authorized current user are incorporated with the direct-viewing optical device to produce a specified change in optical wavefront at an exit pupil. Possible replacement optical elements may have refractive and/or reflective and/or diffractive and/or transmissive characteristics based on current performance viewing factors for a given field of view of the direct-viewing optical device. Some embodiments enable dynamic repositioning and/or transformation of replaceable corrective optical elements responsive to a detected shift of a tracked gaze direction of a current user. Replaceable interchangeable corrective optical elements may be fabricated for current usage or retained in inventory for possible future usage in designated direct-viewing optical devices.

Embodiments disclosed herein are directed to fluid spraying apparatuses, and related systems and methods. The disclosed fluid spraying apparatuses may be used, for example, to spray a medically suitable fluid on a target region of a living subject such as for treating or removing tissue. In an embodiment, a fluid spraying apparatus includes a target designation unit having a target sensor configured to sense a target region of a living subject, a spray mechanism, and a controller. The spray mechanism includes at least one reservoir configured to hold fluid, and a spraying device operably coupled to the at least one reservoir, the spraying device configured to spray the fluid in the at least one reservoir onto the target region. The controller includes control electrical circuitry operably coupled to the spray mechanism and the target designation unit, and configured to control the spray mechanism responsive to the target sensor sensing the target region.

Different embodiments of the heat engine may also incorporate different materials in and/or proximate to the cathode, gate, suppressor, and anode.
Abstract:
An electrical device includes a winding, a primary cooling system, a secondary cooling system, and an actuator. The winding includes an interior portion and an exterior surface. The primary cooling system cools the exterior surface of the winding. The secondary cooling system cools the interior portion of the winding. The actuator is configured to actuate the secondary cooling system in response to a sensed condition of the electrical device or a predicted condition of the electrical device.
Abstract:
Described embodiments include a system, method, and computer program product. A described system includes a receiver circuit that receives a first reference image that includes an objective landmark subsurface feature of a mammalian body part, and a second reference image that includes a present-location landmark subsurface feature of the mammalian body part. A feature matching circuit determines a substantial correspondence between the objective landmark subsurface feature and a first atlas subsurface feature, and a substantial correspondence between the present-location landmark subsurface feature and a second atlas subsurface feature. A location analysis circuit determines a fourth spatial relationship between the destination region of interest and a distal end portion of the body-insertable device deployed operationally proximate to the mammalian body part. An indicator circuit generates informational data indicative of the determined fourth spatial relationship. The system includes a computer-readable media configured to maintain the informational data.
