Abstract: Devices and methods for fabrication of a multiscale porous high-temperature heat exchanger for high-temperature and high-pressure applications are disclosed. The heat exchanger can include a core with macrochannels formed in a checkerboard pattern to facilitate alternative flow of working fluid having hot and cold temperatures between adjacent macrochannels. Each macrochannel can include a two-dimensional microchannel array that further distributes flow throughout the heat exchanger to enhance heat transfer and mechanical strength without significant pressure drop penalty. The heat exchanger can further include a header integrated therewith to distribute working fluid flowing through the heat exchanger through the outlets such that it flows evenly therethrough. Methods of fabricating heat exchangers of this nature are also disclosed.

Abstract: A computerized method for an electronic game includes starting a round of play of the electronic game, and during the round of play monitoring a physiological attribute of a user's body. The method includes determining whether a value of the physical attribute exceeds a threshold level, and changing a chance of winning the round of play if the value of the physical attribute exceeds the threshold level. Changing a chance of winning the round of play may include increasing the chance of winning the round of play from a first chance to a higher second chance, where the round of play is for a game of chance.

Abstract: An automatic scent dispersion device for providing an automatic scent dispersion system that automatically disperses hunting, cover, and training scent. The automatic scent dispersion device generally includes a waterproof case which houses the motor driven pump which derives its power from the battery source that delivers the power first to the switch which in turn delivers the power to the circuit board mounted precise angle sensor and when the precise angle switch circuit is open the self-priming pump is engaged which causes fluid to pass from the reservoir bottle through the rubber pick up line, through the prime relief T connector, into the pump and out the dispersion hose and exiting the dispersion nozzle.
