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.

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: In various embodiments, a touch surface may comprise multiple individual sensors, each of which is capable of mechanical deflection in a direction parallel to the surface, with the device using the touch surface being able to detect such deflection in each sensor. With this capability, the device may be able to detect intended movement of a touch over the touch surface even if no additional sensors are activated by that movement. Such sensors may be useful for detecting very small motions, and may be especially useful for motions in which the shape of the user's thumb results in the same touch area being in contact with the thumb even though the thumb is executing an extension or retraction movement.

Abstract: Various embodiments relate to apparatuses and methods of using light transmission thought living tissue, such as a finger, to detect the flexure of a joint. Light is introduced into the tissue at one point, passes through the tissue, and exits the tissue at a second point where a sensor receives the light as it exits the tissue. Transmission of light through living tissue such as a finger can be affected by movement of the finger. As the finger flexes and, for example, the joints of the finger change angle, the characteristics of the light exiting the tissue, such as the intensity of the light, can change. These changes in characteristics can be used as an indirect means of determining the flexure 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 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 provide 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.
