Abstract: Systems and methods for predicting interactions between objects and predicting a trajectory of an object are presented herein. A system can obtain object data associated with a first object and a second object. The object data can have position data and velocity data for the first object and the second object. Additionally, the system can process the obtained object data to generate a hybrid graph using a graph generator. The hybrid graph can have a first node indicative of the first object and a second node indicative of the second object. Moreover, the system can process, using an interaction prediction model, the generated hybrid graph to predict an interaction type between the first node and the second node. Furthermore, the system can process, using a graph neural network model, the predicted interaction type between the first node and the second node to predict a trajectory of the first object.

Abstract: A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.

Abstract: The invention proposes the design of a pyrotechnic initiator applied in the aerospace field, including three main components: the housing, the burning bridge and the pyrotechnic dose. The housing has a protective effect and increases the power of the pyrotechnic dose, in which the number of threads and the thread length are calculated to ensure to withstand the fire pressure. The burning bridge generates heat to ignite the ignition dose, the diameter of the bridge is calculated to ensure the resistance of the burning bridge. The pyrotechnic dose consists of 3 ingredient doses, which are the ignition dose, the intermediate dose, and the fire-boosting dose. In which, the mass, composition and density of the doses are calculated to ensure that the required working pressure is created.

Abstract: Systems and methods are described for providing wireless power. In some embodiments, a method for wireless power transmission comprises sending, via an antenna of a first wireless power receiver client and during a first tone time block, a beacon signal to a wireless power transmission system. During a first power tick time block of a plurality of power tick time blocks, a wireless power signal is received from an antenna array of the wireless power transmission system. When not sending the beacon signal and when not receiving the wireless power signal, a low power mode is entered that is configured to consume less power than a power consumed by the first wireless power receiver during either the sending of the beacon signal or the receiving of the wireless power signal.

Abstract: A combination of capillary forces and gas pressure is used to control the movement of liquid samples within a microfluidic device. A liquid sample introduced to a proximal portion of a capillary channel of a microfluidic device moves by capillary action partway along the capillary channel. As the liquid sample moves, a pressure of a gas acting upon a distal gas-liquid interface of the liquid sample increases by an amount sufficient to stop further movement of the liquid sample. To initiate further movement of the liquid sample, a pump connected to a distal portion of the capillary channel decreases the pressure of the gas acting upon the distal gas-liquid interface of the liquid sample by an amount sufficient to permit the liquid sample to move by capillary action further along the capillary channel of the microfluidic device.
