Abstract: Methods and systems for operating a moving platform to determine an identity of an unidentified target are disclosed. In an example method to determine the identity of the unidentified target, a first moving platform, configured with a first type of sensor, is caused to move to an area associated with the target. An attempt is made to determine, via the first moving platform and the first type of sensor, the identity of the target. Based on the attempt, a second moving platform, configured with a second type of sensor, is caused to move to the area. The identity of the target is determined via the second moving platform and the second type of sensor.

Abstract: A card connector that is removably fixable to a main body of a carrier system. For example, an outer flange of the card connector may be removably fixed (e.g., with fasteners, such as bolts) to the main body of the carrier system. A protrusion of the card connector may include a connector configured to electrically couple to the plugin card. The protrusion may extend into an interior of the main body when the card connector is removably fixed to the main body, such that the plugin card is disposed entirely within the main body. The card connector provides for a user to easily remove the card connector from the main body (e.g. by unfastening bolts and sliding the card connector out of the main body) and removably fix a new card connector to the main body. The new card connector may include different internal electronics or external porting than the original card connector.

Abstract: A system may be configured to provide a main body, configured to house a plugin card, and a card connector, including a first printed circuit board (PCB) having a backplane configured to electrically couple to the plugin card, a third PCB having a plurality of ruggedized connectors configured to couple to an external system, and a second PCB interposed between the first and third PCBs. The processor may be mounted on the second PCB and may determine a state of at least a portion of the system based on a sensor output, an input signal and/or an output signal, and an internal data value. The state may comprise at least one of operational, less than operational, tampered, needing maintenance, needing repair, and not working. And the determination may be performed via one or more criteria being satisfied.

Abstract: A system may include a plurality of rack-mountable, ruggedized drawers, each comprising a main body, a set of fans, a power supply, and a card connector. Connections may be provided, via a backplane of each of the card connectors, to a set of plugin cards each installed in the respective main body. A processor of the card connector of one of the drawers may represent the drawers by communicating information with an external third party.

Abstract: Systems and methods are provided for detecting user-object interaction in mixed-reality environments. A mixed-reality system detects a controller gesture with an associated controller orientation in the mixed-reality environment. The mixed-reality system then determines an interaction region for the controller gesture and identifies one or more virtual objects within the interaction region. The virtual objects each have an associated orientation affinity. Subsequently, the mixed-reality system determines an orientation similarity score between the controller orientation and the orientation affinity for each virtual object within the interaction region. In response to determining that at least one orientation similarity score exceeds a predetermined threshold, the mixed-reality system executes an interaction between the controller and the virtual object that has the greatest orientation similarity score.

The first and second mating features may be dovetail elements.

Abstract: A method of assuring integrity of range measurements and position solutions comprises obtaining range measurement statistics between nodes in a network, performing a snapshot integrity test for the range measurement statistics, and performing a sequential integrity test using the range measurement statistics. The snapshot integrity test comprises using Gram matrices along with a current configuration of the nodes; performing a singular value consistency check using the Gram matrices against a user selected threshold; and detecting/excluding range measurement statistics with instantaneous errors that cause the singular value to exceed the threshold.

Abstract: A compact firearm has a frame including a barrel defining a chamber, the frame being movable between a closed condition in which the firearm is operable to discharge a cartridge in the chamber, and an open condition in which the chamber is open for loading, a latch movable between a latched condition to retain the frame in the closed condition, and an unlatched condition to enable movement of the frame to the open condition, a firing mechanism connected to the frame and operable in response to actuation to discharge the cartridge in the chamber, and a trigger element operably connected to the firing mechanism to selectably actuate the firing mechanism, and operably connected to the latch to move the latch to the unlatched condition. The trigger element may be operable to selectably actuate the firing mechanism in response to movement in a first direction.

Abstract: A head-mounted display comprises a display device and an outward-facing depth camera. A storage machine comprises instructions executable by a logic machine to present one or more virtual objects on the display device, to receive information from the depth camera about an environment, and to determine a position of the head-mounted display within the environment. Based on the position of the head-mounted display, a position of a joint of a user's arm is inferred. Based on the information received from the depth camera, a position of a user's hand is determined. A ray is cast from a portion of the user's hand based on the position of the joint of the user's arm and the position of the user's hand. Responsive to the ray intersecting with one or more control points of a virtual object, the user is provided with an indication that the virtual object is being targeted.

Abstract: In one embodiment, a method of tracking multiple objects with a probabilistic hypothesis density filter is provided. The method includes obtaining measurements corresponding to a first object with at least one sensor, the at least one sensor providing one or more first track IDs for the measurements. A Tk+1 first predicted intensity is generated for the first object based on a Tk first track intensity. A Tk+1 measurement from a first sensor of the at least one sensors is obtained, the first sensor providing a second track ID for the Tk+1 measurement. The second track ID is compared to the one or more first track IDs, and the Tk+1 first predicted intensity is selectively updated with the Tk+1 measurement based on whether the second track ID matches any of the one or more first track IDs to generate a Tk+1 first measurement-to-track intensity for the first object.

Abstract: A sound isolation assembly comprising: a center ferrule; a top grommet isolator; a bottom grommet isolator; a spring; and a furring channel engagement portion. The sound isolation assembly is configured to engage with a structure and a furring channel, which itself is connected to a ceiling panel, such that the noise passing from one floor to the other is lessened as compared to a control system that does not use the sound isolation assembly. The spring may be steel and the grommet isolators may be rubber or the like, and the combination of the steel spring and grommet isolators reduces noise.
