Abstract: A system and method for compressing synthetic aperture radar (SAR) images with enhanced phase recovery and unwrapping capabilities is disclosed. The system performs preprocessing on input SAR images, applies discrete cosine transform (DCT) to create subbands, and utilizes a multi-pass amplitude compression technique. A specialized neural network performs phase unwrapping using compressed amplitude information and interferogram wrapped phase data. The system employs a channel-wise transformer fusion block (CTFB) for feature fusion and a multi-stage context recovery subsystem with optimized loss functions for both amplitude and phase recovery. The method achieves improved compression efficiency and phase recovery accuracy, particularly beneficial for Interferometric SAR (InSAR) applications.

Abstract: An electromagnetic intramedullary nail screw positioning system is used to assist an orthopaedic surgeon to correctly aligned a screw drill guide with a screw receiving aperture in an intramedullary nail during surgery. However due to the large number of different types of intramedullary nail, the system must be calibrated during each surgery. An improved calibration system is described that no longer requires the surgeon to perform the calibration during the surgery in order to save time and improve robustness. The system is periodically calibrated and a memory stores offset information for a range of nails types relative to a reference nail. During surgery, the surgeon enters a nail identifier, and the system looks up the associated offset and applies this offset to the measured signals to guide alignment of the screw drill guide with the screw receiving aperture.

Abstract: In an exemplary embodiment, a security sensor is present in a POS terminal between the keypad and a processor. The security sensor is configured to detect an unauthorized probe through the keypad and implement a security protocol. In an exemplary embodiment, the security sensor is a serpentine conductive circuit screen printed on the polyester film. The serpentine conductive circuit may cover almost all of the polyester film. For example, the serpentine conductive circuit may cover 90% to 100% of the film. Furthermore, in an exemplary embodiment, the serpentine conductive circuit limited to a section of the polyester film. For example, the serpentine conductive circuit may be on only ¼ of the film. This embodiment has the advantage of printing the serpentine conductive circuit on the critical security areas and leaving the non-critical areas with blank polyester film.

Abstract: In an exemplary embodiment, a stylus operates with a capacitive touch screen only when the stylus tip is in contact with the touch screen. The stylus is used as a sensor to determine the location where a user is touching the surface of a capacitive touch screen, but is not active until the stylus tip is pressed against the touch screen. In an exemplary embodiment, pressing the stylus tip against the touch screen activates the stylus by creating a physical separation in the circuit and disconnecting the stylus tip from ground. When the stylus tip is no longer grounded, it becomes active and is able to operate with a capacitive touch screen. In an exemplary embodiment, signal attenuation may be performed by diverting the sense signal to ground via a capacitor or other electronic component.

Abstract: Apparatus and associated methods for actuating variable stiffness material (VSM) structures and achieving deformation of the structures. The apparatus and the associated methods use internal embedded actuation elements and/or externally attached elements to the VSM structures to achieve the desired deformation. In particular, the actuation can be changed due to the variable stiffness nature of the materials. That is, the invention provides the ability to control the deformation of structures using local stiffness control over subregions of the component in addition to or in substitution for actuation. Furthermore, the invention exploits the variable stiffness properties of the VSM structures to enable new functionalities impossible to realize with conventional constant stiffness materials.
