Abstract:
A topography detection mechanism may measure surface height of a side read/write track while the read/write head is interacting with a current read/write track. A memory may store the measured surface height.
Abstract:
Described embodiments include a portable electronic device. The device includes a shell housing components of the portable electronic device and a heat-generating component. The device includes a contact sensor configured to determine a user touch to the shell. The device includes a temperature sensor configured to determine an exterior temperature of the shell. The device includes a thermal manager configured to reduce the exterior shell temperature by regulating heat generation by the heat-generating component. The regulating heat generation is responsive to the determined user touch and the measured determined temperature of the shell.

A method of converting user-selected printed text to a synthesized image sequence is provided. The method includes capturing a first image of printed text and generating a model information associated with the text.
Abstract:
A mold may include a plurality of nanostructures configured to form a lithographic pattern when imprinted into a material. Imprinting may include imprinting the mold a first predetermined distance, modifying a temperature of the material, and altering a position of the mold based on the temperature modification. One or more thermal elements may alter a temperature of a first section of the material and/or one or more nanostructures for a predetermined pulse time less than an equilibrium time required for the mold and/or material to reach a stable temperature state. A first thermal element may selectively alter the temperature of a first section of the material and/or a first nanostructure and a second thermal element may selectively alter the temperature of a second section of the material and/or a second nanostructure. The one or more thermal elements may include one or more thermoelectric elements.
Abstract:
An active torso support that controls force applied to one or more portions of a torso of a subject in response to detected gait of the subject is described. For example, the torso support can be a back brace for providing support to the back of a subject to limit or prevent injury or discomfort. The active torso support includes one or more elements for applying force to the torso of the subject, positioned on the torso of the subject by a positioning element, which may include a belt, for example. Gait of the subject can be determined through analysis of signals from one or more sensors located on the active torso support and/or at a location remote from the active torso support.
Abstract:
An improved heat engine is disclosed. The heat engine comprises at least one heat pipe containing a working fluid flowing in a thermal cycle between vapor phase at an evaporator end and liquid phase at a condenser end. Heat pipe configurations for high-efficiency/high-performance heat engines are disclosed. The heat pipe may have an improved capillary structure configuration with characteristic pore sizes between 1μ and 1 nm (e.g. formed through nano- or micro-fabrication techniques) and a continuous or stepwise gradient in pore size along the capillary flow direction. The heat engine may have an improved generator assembly configuration that comprises an expander (e.g. rotary/turbine or reciprocating piston machine) and generator along with magnetic bearings, magnetic couplings and/or magnetic gearing. The expander-generator may be wholly or partially sealed within the heat pipe. A heat engine system (e.g. individual heat engine or array of heat engines in series and/or in parallel) for conversion of thermal energy to useful work (including heat engines operating from a common heat source) is also disclosed. The system can be installed in a vehicle or facility to generate electricity.
Abstract:
Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The physiological parameter is determined from a signal sensed from the eye of a subject according to a schedule, under the control of a scheduling controller.
Abstract:
A field emission device is configured as a heat engine. Different embodiments of the heat engine may have different configurations that may include a cathode, gate, suppressor, and anode arranged in different ways according to a particular embodiment. Different embodiments of the heat engine may also incorporate different materials in and/or proximate to the cathode, gate, suppressor, and anode.
Abstract:
A system for directing a bird away from equipment includes an item of equipment and a detector configured to detect a bird that could be harmed by or that could harm the equipment and to determine the proximity of the bird to the equipment. The system also includes an unmanned aerial vehicle and a pilot system configured to control the unmanned aerial vehicle.
Abstract:
A system for facilitating cloud formation and cloud precipitation includes a controller and a beam emitter that is responsive to the controller. The beam emitter is configured to emit a beam to form charged particles within an atmospheric zone containing water vapor. The charged particles enhance the formation of cloud condensation nuclei such that water vapor condenses on the cloud condensation nuclei forming cloud droplets. The system further includes a sensor configured to detect a cloud status and output a signal corresponding to the cloud status to the controller.
