A new digital image/video camera that directly acquires random projections of the incident light field without first collecting the pixels/voxels. In one preferred embodiment, the camera employs a digital micromirror array to perform optical calculations of linear projections of an image onto pseudorandom binary patterns. Its hallmarks include the ability to obtain an image with only a single detection element while measuring the image/video fewer times than the number of pixels or voxels—this can significantly reduce the computation required for image/video acquisition/encoding. Since the system features a single photon detector, it can also be adapted to image at wavelengths that are currently impossible with conventional CCD and CMOS imagers.

An intervertebral implant is provided for insertion between a first vertebral body and a second vertebral body defining an intervertebral space. The implant includes a first anchoring part for anchoring at the first vertebral body, a second anchoring part for anchoring at the second vertebral body, and a joint configured to connect the first and second anchoring parts together. The joint includes a first joint part carried by the first anchoring part, and a second joint part carried by the second anchoring part. The implant further includes at least one restoring device adapted to exert a restoring force on the first or second joint part. The restoring force of the at least one restoring device transfers the first or second joint part from a deflected position back to a normal position and/or limits movement of the first or second joint part away from the normal position.

A stent, or device for repair and reconstruction of the spinal disc wall, or annulus fibrosus, after surgical incision or pathologic rupture, which is inserted through an aperture into the subannular space. The stent has radial extensions which are caused or allowed to expand into an expanded configuration to bridge the aperture. The stent thereby occludes the defective region from the inside of the vertebral disc and prevents the migration of nucleus pulposus therethrough, while also providing a scaffold for tissue growth.

A computerized aircraft system, such as an unmanned aircraft system (UAS) is provided with a cloud detection system. The UAS includes a monocular electro-optic or infra-red camera which acquires consecutively, in real time, a plurality of images within a field of view of the camera.

A plurality of master desktop images for a plurality of users are stored at a plurality of geographically diverse data centers. At a first one of the data centers, a virtual desktop is constructed for a remote client. The virtual desktop is constructed from a given one of the master desktop images at the first one of the data centers and an individualized delta image for a user associated with the remote client. When it is determined that the remote client is at a geographical location wherein the first one of the data centers is not the closest one of the data centers to the remote client, the virtual desktop for the remote client is reconstructed at a second, closest, one of the data centers. The virtual desktop is reconstructed from a given one of the master desktop images at the second one of the data centers and the individualized delta image for the user associated with the remote client. A copy of the individualized delta image is moved from the first one of the data centers to the second one of the data centers to facilitate reconstructing the virtual desktop.

Dynamic projection of at least first and second patterns contributes detectable disparity onto a scene that includes a target object. The scene is imaged with two-dimensional cameras whose acquired imagery includes disparity contributions whose presence enable a three-dimensional reconstruction depth map to be rapidly and accurately generated. In one embodiment coherent light is input to a first DOE within whose near range output is disposed a second DOE, whose far range output projects an image. Electronically varying effective optical distance between the two DOEs varies the pattern projected from the second DOE. A processor system and algorithms enable dynamic intelligent selection of projected patterns to more readily discern target object characteristics: shape, size, velocity. Patterns can implement spatio-temporal depth reconstruction, spatio-temporal depth reconstruction, and even single-camera spatio-temporal light coding reconstruction. Target objects may be scanned or may make gestures that are rapidly detected and recognized by the system and method.
