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: 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 when the eye of the subject is properly aligned with regard to an interrogation signal source and/or response signal sensor.

Abstract: Methods and system 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 gaze direction of the eye of the subject is determined and an interrogation signal source and/or response signal sensor are moved into alignment with the eye using an actuator to facilitate detection of the signal from the eye of the subject.

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 system includes a gaze attractor for attracting the gaze of the subject to cause an eye of the subject to move into alignment with regard to an interrogation signal source and/or response signal sensor to facilitate detection of a signal from the eye of the subject.

Abstract: A system for altering water properties in an outdoor body of water includes a holding vessel configured to hold water. The holding vessel has at least one wall extending above a mean surface water level. The system also includes at least one conduit extending downward from the holding vessel. The at least one conduit has a length extending to a depth at which at least one property of water at the depth differs substantially from that of water at the surface. The system further includes at least one aperture formed in at least one of the holding vessel or the at least one conduit and located at a distance below the mean surface water level. Further still, the system includes at least one one way valve coupled to the at least one aperture and allowing flow of water in only one direction.

Abstract: A system is described generally for providing a structure or structures for altering water surface temperature. The system includes a holding vessel configured to hold water. The holding vessel has at least one wall coupled to a lowermost portion. The at least one wall extends above the water level and the lowermost portion is configured to be submerged. At least one conduit extends from the lower side of the holding vessel. The at least one conduit has a length extending to a depth at which a property of water at the depth is substantially different from that of the water at the surface.

Abstract: A method is generally described which includes environmental alteration. The method includes determining a placement of at least one vessel capable of moving water to lower depths in the water via wave induced downwelling. The method also includes placing the at least one vessel in the determined placement. Further, the method includes generating movement of the water adjacent the surface of the water in response to the placing.
