Abstract: Devices that use additively-manufactured connectible unit cells are described in which each unit cell comprises materials and voids. The materials occupy a certain volume of the unit cell with the voids occupying the balance of the volume. The unit cells form a lattice structure, which exhibits smooth transitions between each of the adjacent unit cells. The lattice structure exhibits periodicity along one (1), two (2), or all three (3) dimensions. The materials have a thickness that is a function of the material location within the device.

Abstract: The disclosure relates to a system and method for valuation and publication of a diamond's market value that connects diamond purchasers to diamond sellers and provides to both a reasonable estimate of the diamonds fair market value. The invention analyzes a diamond's physical properties and compares it to international wholesale prices for similar stones, adjusts the price based on these criteria, stores this information in an accessible means, and then provides the information to buyer of the diamond.

Abstract: A method for determining an angle of incidence of periodic optical signals is provided. The method includes detecting whether the periodic optical signals are present; generating a pulsed output when the periodic optical signals are present, the pulsed output corresponding to peaks in the periodic optical signals; predicting a timing of the periodic optical signals from the pulsed output; controlling a gated detector array to take a first reading and a second reading of the periodic optical signals based upon the timing, the first reading being out of phase with the timing and the second reading being in phase with the timing; and generating the angle of incidence by filtering the first reading from the second reading.

Abstract: A combat maneuver training system includes a shooter platform (1) and a target platform (2). A first step is performed at the shooter platform, and operates a rangefinder (18) to determine a laser range of a shooter platform weapon (1A). At the target platform, the operation of the rangefinder is detected, and a controller (10) of the target platform transmits a current location (e.g. from GPS) of the target platform. At the shooter platform, when the target platform is in range, the controller (10) calculates an impact point of a simulated ordinance on the target platform and an impact time, and then transmits this and other information to the target platform. Meanwhile, an operator of the target platform, detecting the rangefinding operation, begins to maneuver the target platform to evade the simulated ordinance.
