Abstract: Disclosed is an electronically adjustable joint, and associated systems and methods. A joint position of a multiple-axis joint, e.g., a 3-axis joint, can be tracked, as the joint moves through two or more dimensions. In an illustrative embodiment, the joint can provide a mechanical equivalent of a physical joint, e.g., a shoulder, elbow, hip, or knee, which can accommodate motion in rotational angle and/or tilt angle. In some embodiments, the joint includes electronically adjustable friction. An illustrative application provides electronically adjustable joints for an aging simulation suit, wherein one or more joints can be controllably stiffened in selective ranges, such that a wearer of the suit can experience the effects of aging, arthritis and/or other ailments. In an illustrative embodiment, a sensor can use four discrete 2-axis magnetometers to calculate the position of the magnet on the arm of the joint, to continuously sense and track the angle of the joint.

Abstract: Methods, devices and systems are disclosed for improved depth perception in stereoscopic night vision devices. Among these are embodiments for aligning information overlays in the stereo view with associated objects, and for generating stereo information from single lenses or intensifiers. In some illustrative embodiments, a camera and position sensor are provided for at least two viewers, e.g., a pilot and a copilot, such that when a scene overlaps between viewers, the system produces a stereoptic scene, in which the users can more accurately determine a difference in depth between two or more distant objects. An illustrative binocular night vision system uses a high-resolution depth map to present binocular images to a user. In some embodiments, supplementary content can be overlaid, with an appropriate binocular disparity that is based on the depth map.

Abstract: Disclosed are improved methods, systems and devices for color night vision that reduce the number of intensifiers and/or decrease noise. In some embodiments, color night vision is provided in system in which multiple spectral bands are maintained, filtered separately, and then recombined in a unique three-lens-filtering setup. An illustrative four-camera night vision system is unique in that its first three cameras separately filter different bands using a subtractive Cyan, Magenta and Yellow (CMY) color filtering-process, while its fourth camera is used to sense either additional IR illuminators or a luminance channel to increase brightness. In some embodiments, the color night vision is implemented to distinguish details of an image in low light. The unique application of the three-lens subtractive CMY filtering allows for better photon scavenging and preservation of important color information.

Abstract: A gaming machine includes a cabinet at least partially defining a cavity opening and an internal cavity at least partially visible through the cavity opening, a primary display, a secondary display positioned within the internal cavity and visible through the cavity opening, a display movement assembly coupled to the primary display, and logic circuitry. The display movement assembly selectively moves the primary display between an open position and a closed position in which the primary display blocks visibility through the cavity opening. The logic circuitry causes the primary display in the closed position to present a first portion of a game, causes the display movement assembly to move the primary display to the open position to expose the cavity opening and the secondary display, and, in response to the secondary display being exposed, causes the secondary display to present a second portion of the game.

Abstract: Various embodiments relate to apparatuses and methods of using light transmission thought compressed living tissue to detect force. Transmission of light through living tissue such as a finger is affected by how much the tissue is compressed, for example by the finger being pressing on a surface. Light is introduced into the tissue, passes through the tissue, and a sensor receives the light exiting the tissue. The compression of the tissue can be determined using various characteristics of the received light, such as the light intensity, as determined based at least partly on sensor readings.
