International Classification:

H04L 9/00
H04L 9/12

US Classification:

380 44

Abstract:

An apparatus for generating a shared quantum key between a sender and a receiver comprises a sending apparatus which generates entangled photon pairs, and a receiving apparatus. A shared quantum key can be generated using temporal coincidences between photon detection events. For example, coincidences may be determined between sender and receiver photon detection events using detection data shared through a non-secure communications link between the sender and receiver. The quantum key can be used in encrypted communications. Similar apparatus and methods can be used for quantum imaging.

International Classification:

H04N 13/00

US Classification:

348 42

Abstract:

A system and method of determining three-dimensional data for an object by performing optical flow analysis to calculate surface profile analysis for a group of monocular component images that vary wavelength distribution, and determining three-dimensional data relating to the object from the component images and the surface profile analysis. Stereo image features are obtained from a single monocular polychromatic raw image or multiple monocular grayscale images having known spectral imaging collection data. Apparatus are described which allow three-dimensional data for an object to be determined from one or more two-dimensional images of the object.

Inventors:

Ronald Everett Meyers - Columbia MD, US
David Lawrence Rosen - Rockville MD, US

International Classification:

H01J 65/06

US Classification:

2504591

Abstract:

A method and system for investigating properties of an object comprising: a transmitter, including a radiation source, the transmitter providing incident radiation having a plurality of predetermined polarization states; the incident radiation illuminating an object and thereby causing the object to emit photoemission; a receiver, receiving photoemission from the object when the object is illuminated by the incident radiation, the receiver including a detector, the detector providing photoemission intensity data; and signal processing circuitry, in electrical communication with the detector, the signal processing circuitry determining three-dimensional information relating to the object from the photoemission intensity data for each of the plurality of incident polarization states.

International Classification:

G01J 1/58

US Classification:

2504581, 2504591, 2504611, 2502521

Abstract:

An apparatus for determining the depolarization efficiency of a environment includes a transmitter, a receiver, and signal processing circuitry. A reference object is located within the environment at a reference distance. The transmitter includes a radiation source providing incident radiation that has an initial polarization as it enters the environment. The receiver receives returned radiation from the reference, which may be diffuse reflection or photoluminescence. The signal processing circuitry calculates the depolarization efficiency of the environment from the initial polarization, luminescence or final polarization, and the reference distance. A method of determining depolarization efficiency includes directing incident radiation having initial polarization through an environment onto a reference, detecting returned radiation from the reference, and calculating the depolarization efficiency using the initial polarization and the luminescence or final polarization.

US Classification:

705 2, 705 35

Abstract:

Systems, methods, and computer program media for creating, managing, backing, and transferring health care credits are described. Health care credits may be implemented as freely transferable financial instruments whose initial value is based on costs or savings generated by an individual, or by a health care provider, that are associated with a health-related metric or a health benefiting behavior(s).

US Classification:

705 2, 705 4

Abstract:

Systems and methods for exchanging health care credits are described. Health care credits are transferable units of value representing good health, an improvement in health, or maintenance of health by an individual. The health care credits may be bought, sold, exchanged for goods and services, gifted or otherwise conveyed from one owner to another. Also disclosed are exchanges and markets for buying, selling, and trading health care credits, as well as derivative securities. The derivative securities or products are based on either the flow of health care credits through the system, or on health care information, which may have been generated to implement health care credit awards.

US Classification:

705 4

Abstract:

Systems and methods to manage health insurance are described. A subscriber of a health insurance plan with an insurance provider can receive health treatment from a health care provider. The subscriber can further have an account established with an account servicer, wherein the account comprises an amount of health care credits acquired or earned by the subscriber. The health care credits can be accepted as payment and can be applied to a balance due for the health treatment. When the health care credits are redeemed by the subscriber, the account servicer can deduct an appropriate amount of health care credits from the account of the subscriber.
