Abstract: Embodiments relate to a method for generating an image comprising a graphical representation. The method includes determining a transformation relationship for a unit cell of a graphical representation of an original image. The transformation relationship is based on position information of grid vertices of the unit cell of the original image graphical representation and position information of grid vertices of a unit cell of a reference grid arrangement of the image to be generated. The method further includes determining position information of a one or more pixels of the unit cell of the original image graphical representation based on the transformation relationship. The method further includes applying data information sampled at the one or more pixels of the unit cell of the original image graphical representation to one or more pixels of the unit cell of the reference grid arrangement.

Abstract: Systems and methods for use in measuring sympathetic nervous system activity or blood vessel autoregulation corrected for sympathetic activity. The choroid in the human eye is imaged and, using the resulting image, the vascular perfusion density (VPD) in the choroid is measured. VPD provides a measurement that is directly related to sympathetic nervous system activity. The effect of stimuli on sympathetic nervous system activity can be measured by comparing pre-stimuli VPD measurements with post-stimuli measurements. Quantifying VPD can be performed by determining pixel density within specific areas of the choroid image. Altered sympathetic nervous system activity can be detected in a subject by comparing that subject's VPD measurements to baseline VPD measurements from healthy individuals. Blood vessel autoregulation can be measured by imaging changes in other blood vessels in the eye and correcting with choroid VPD measurements of sympathetic activity.

Abstract: Systems and methods for use in measuring sympathetic nervous system activity or blood vessel autoregulation corrected for sympathetic activity.

Abstract: Systems and method of mapping spaces include a head-mounted sensor array. The array includes sensors configured to both measure distances within spaces and capture images of the spaces. This data may be used to generate continuously navigable virtual simulations of the spaces. Mapping of the spaces may include movable objects such as doors, transparent objects such as windows, and transitions between floors.

Abstract: Touchscreen-enabled devices are provided to display images of either real or virtual environments, the devices having user interfaces including a graphical overlay laid over the images for navigating the environments. The device can interpret gestures made by the user on the touchscreen as commands, and the graphical overlay guides the user as to where to make the gestures to achieve intended maneuvers such as translations of the point of view and rotations of the point of view within the displayed environment. The graphical overlay can comprise only a single symbol, and gestures that originate within the area of the display marked by the symbol are differentiated from those gestures originating from outside of the symbol, where the differentiated gestures control translation and rotation, respectively. This allows for one-finger navigation of the environment.

Abstract: A real estate sign lighting system for selectively illuminating a real estate sign hanging from a real estate sign post. The real estate lighting system includes a real estate hood that is secured to a horizontal bar of the real estate sign post. Bright white light emitting diodes are secured to the underside of the real estate hood and operate to illuminate the real estate sign. A housing is mountable on the real estate hood, and supports thin-filmed solar panels secured to the top side of the housing. The thin-filmed solar panels provide charging power to rechargeable batteries located within the housing. A control circuit uses input from a light sensor to selectively apply power from the rechargeable batteries to the bright white light emitting diodes.

Abstract: A detection system includes a collector for capturing a first particle, a first device for determining a class of a second particle, a second device for determining an identity of the first particle, and a control system. The control system is configured to select a test to be performed by the second device based on the class determined by the first device.

Abstract: Systems and methods treat plasma carrying contaminants and cellular matter that are capable of entraining contaminants. The systems and methods separate cellular matter from the plasma by filtration, thereby removing contaminants entrained within the cellular matter. The system and methods add to the plasma a photoactive material. The systems and methods emit radiation at a selected wavelength into the plasma to activate the photoactive material and thereby eradicate the contaminant that is free of entrainment by cellular matter.

Abstract: A system for generating a liquid sample includes a chamber adapted to hold a fluid, an air filter configured to be received in the chamber, a mechanism for releasing at least a portion of a particulate disposed on the filter into the fluid located in the chamber, and a structure for removing at least a portion of the particulate containing fluid from the chamber.
