Abstract: A device configured to move in a viscoelastic media, the device comprising: a main-body comprising a first material, configured to respond to a first threshold of a stimulus field; and one or more memory shaped elements comprising a second material, configured to respond to a second threshold of a stimuli field; wherein the first material is selected to enable manipulation of the main-body's direction in the viscoelastic media; and wherein second material is selected to enable manipulation of the configuration of the memory shaped element.

Abstract: A carrier device and methods of use are described. The device and methods are directed toward implanting in biological tissue and optionally for propelling in a biological tissue and for releasing a medical payload in a biological tissue according to remote trigger. The carrier device includes at least one element sensitive to the external stimuli. When external stimuli are sent through the tissue, the responsive element provides release of the functional material. In some embodiments, payload release can be started, stopped, and restarted at a later time or place. Individual carrier devices can be selectively triggered by implementing different elements in the devices, each element is sensitive to different stimuli. In addition to payload release, devices of this invention are equipped with a propelling element, the propelling element is responsive to external stimuli that enables propulsion and navigation of the device.

Abstract: A computer-implemented method includes receiving a depth map (30) of a scene containing a body of a humanoid subject (28). The depth map includes a matrix of pixels (32), each corresponding to a respective location in the scene and having a respective pixel value indicative of a distance from a reference location to the respective location. The depth map is segmented so as to find a contour (64) of the body. The contour is processed in order to identify a torso (70) and one or more limbs (76, 78, 80, 82) of the subject. An input is generated to control an application program running on a computer by analyzing a disposition of at least one of the identified limbs in the depth map.
