A method is disclosed for detecting and locating a blast, including muzzle flash, created by the launch of a projectile from a gun barrel, rocket tube or similar device, generally associated with weapons fire. The method is used in conjunction with electro-optical imaging sensors and provides the azimuth and elevation from the detecting sensor to the launch location of the blast and also provides the weapon classification.

Systems and methods for capturing an orbiting image of a subject are disclosed. The system includes a rotatable turntable mountable to an overhead surface with a spindle formed therein and a retractable line extending therefrom at a proximal end thereof. First and second lines extend from a distal end of retractable line in opposite directions as retractable line is extended from an exterior of rotatable turntable. The system further includes an imaging assembly with a housing and an interior compartment in which housing includes first and second rotors at first and second ends thereof such that first and second lines are connected to first and second rotors. Interior compartment receives a multimedia device attached thereto and is at least partially visible from an exterior of housing. A remote control is configured to control the rotatable turntable to in turn control speed of rotation of imaging assembly, and the length of line extended or retracted from/to spindle, and further configured to control first and second rotors to in turn control angle of multimedia device. Imaging assembly is rotated from above the subject along a rotation path to enable 360 degree orbiting image capture while the subject is in motion or static during operation.

Augmented reality apparatus and methods of use are provided with secure persistent digital content linked to a location coordinates. More specifically, the present invention links a physical location with digital content to enable a user interface with augmented reality that combines aspects of the physical area with location specific digital content. According to the present invention, digital content remains persistent with a location even if visual aspects of the location change. Access to the digital content may be constrained to Agents physically located in an area of digital content interaction based upon location coordinates of the Agent.

The disclosure provides an example of a system including a radio frequency (RF) wireless communication network (network) including a plurality of nodes in an area and a computer coupled to the network. Each of the nodes includes a transmitter and a receiver. At plurality of times, each transmitter transmits RF spectrum signals (signals) and each receiver receives the signals and also generates an indicator data of a signal characteristic of the received signal propagated in the network. When each time among the plurality of times is a current time, the computer obtains the indicator data of the signal, determines a modification in the indicator data at the current time from the indicator data at a preceding time due to a movement of an occupant in the area and detect an occupancy condition in the area based on the modification in the indicator data and a parameter of a configuration of the network.

Systems that enable observing celestial bodies during daylight or in under cloudy conditions.

A method for calibrating a value of sampling precision of an optical sensor for tracking includes: reading a precision variance and a setting precision value from a memory device; measuring the sampling precision of the optical sensor under a normal mode to generate an actually measured precision value; calculating a normalized value that is proportional to the actually measured precision value according to the precision variance, the actually measured precision value, and the setting precision value; and, calibrating the actually measured precision value by using the normalized value.

Provided are methods and systems for identifying location of light sources from airborne aircraft. Light sources are ground based and may be low power lasers and other like devices. An aircraft equipped with a detecting module, such as a camera of a ground maneuver camera system, may defect light source output and associate this output with the relative position of the aircraft to the light source. This information may be analyzed together with aircraft location information (at the time of light source detection) to generate a light source location estimate. In some embodiments, other information, such as transmission from other aircraft and/or ground based nodes can be used. The estimate may be transmitted to a ground based node, such as a law enforcement unit. The data from multiple aircraft and/or ground based nodes may be aggregated to more precisely identify the light source location.
