Abstract: A reflecting prism has an input surface, an output surface, a first reflection surface, a second reflection surface, and a third reflection surface. The reflecting prism has a first refractive index, such that the first, second, and third reflection surfaces interface with an external medium having a second refractive index less than the first refractive index. This interface defines a critical angle for total internal reflection for each of the first, second, and third reflection surfaces. Light is received at the input surface of a prism body of a reflecting prism and is transmitted along a first internal optical path segment of an optical path to the first reflection surface. The angle of incidence of the first internal optical path segment with respect to the first reflection surface is greater than the critical angle for the first reflection surface, thereby causing the light to be reflected via total internal reflection.

The flexible connection also contains internal and external pressure across the connection. The flexible connection includes an articulation mechanism that interconnects the vertical cold water conveying pipe and the platform or a pipe on the platform, and a flexible, fluid impermeable bellows.

Abstract: A system and method for using a receiving wireless device to passively detect target wireless devices or access points, quantify signal strengths of the target wireless devices or access points, and accurately identify a position for, or geolocate, the target wireless devices or access points. A position of the receiving wireless device is determined and correlated with a signal strength received from a target wireless device taken from multiple positions of the receiving wireless device. A trilateration algorithm is applied to the correlated date to obtain coarse geographic positions for the target wireless device, then a filtering algorithm is applied to obtain an accurate position for the target wireless device, which is in turn displayed to a user of the receiving wireless device.

Abstract: Mechanisms for spatially isolating a region of interest (ROI) in a scene are disclosed. A first sensor generates sensor data that quantifies energy received from a scene within a field of view (FOV) of the first sensor to generate a real-time FOV full motion video.
