Abstract: The present disclosure is directed to devices and methods for synchronizing capturing of spectral images, capturing of thermal images, and capturing of panchromatic images. A thermal imaging device of an aerial vehicle captures a sequence of thermal images. Capturing of spectral images by a spectral imaging device of the aerial vehicle is synchronized with the capturing of the thermal images. Capturing of panchromatic images is synchronized with the capturing of thermal images. Irradiance data indicative of a background temperature is sensed. A digital surface model of an area of interest is generated based on the sequence of spectral images. An emissivity of a target is estimated and a temperature of a pixel of the digital surface model of the target is estimated based on the sequence of thermal images, the irradiance data indicative of the background temperature and the estimated emissivity of the target.

Abstract: An online game of chance and methods of conducting and playing the game on a virtual instant ticket are disclosed. The game is based on a map having multiple branches and nodes, where a desired path is selected by clicking on the branch or node as play progresses between a starting point and multiple finishing points. Each available branch or node that is selected results in a prize value being increased, decreased, or a token being awarded for later use in the game. In a single player mode, a final prize is awarded to the player. In multiple player modes, the final prize is divided among the players according to predetermined criteria.

Abstract: An online game of chance that produces a multi-player extension to an individual, instant lottery-type game and a method of playing the game are disclosed. The game comprises a first, individual phase of play using a virtual game substrate and a second, group phase of play comprising a plurality of virtual game substrates from first phase of play that are arrayed in a matrix. The first, individual phase of play is based on in instant lottery version of the well-known game of tic-tac-toe; the object being to match a plurality of game pieces, e.g., three, in one of a contiguous row, column, and diagonal. The object of the second phase of play is to use the combination of virtual game substrates to produce a match with one or more predetermined winning array combinations. This provides each individual participant with a second chance of winning. With the second phase of play, the combination of virtual game substrates is also movable, which produces even more opportunities for participants to win a prize.

Abstract: An inflator for automatically inflating an inflatable article, such as a personal flotation vest, upon immersion in water. A plunger is mounted in a housing and is movable with respect to a pressurized gas canister attached to the housing. An actuator mechanism, mounted within the housing, acts on the plunger to move the plunger to pierce the canistor to release the pressurized gas through the housing to the inflatable article attached to the housing. A pair of spaced water sensor probes provide a signal to a control device mounted within the housing when immersed in water. The control device automatically activates the actuator to drive the piercing end of the plunger into the canister. A manual lanyard is extensibly mounted within the housing and is connected to a link and lever to drive the plunger into the canister when the lanyard is pulled outward from the housing.
