Abstract: Systems comprising a combination of the handheld imaging system with a nanoparticle multimodal contrast agent are disclosed. The imaging system exploits the advantages of both near-infrared emission and the photoacoustic effect by employing calcium phosphosilicate nanocolloid that encapsulates NIR and CT/MRI contrast agents for enhanced deep tissue imaging as well as a portable NIR/PA system using a tunable pulsed laser, CCD imaging technology and acoustic transducer arrays. Methods for using the system, for example in rapid diagnosis of trauma such as that inflicted on a battlefield, are provided.

Abstract: A collision avoidance system for an airplane under tow may include a sensing device configured to capture image data of at least a portion of the airplane and an object while the airplane is being towed. The sensing device may be located remotely to both the airplane and the object. Positions of two or more features of the airplane may be determined based on the image data. A bounding box encompassing the airplane may be generated based, at least in part, on the positions of the two or more features. Additionally, based on a comparison of the position of an object relative to the bounding box, it may be determined whether the object is within a predetermined distance from the airplane.

Abstract: An example ultrasound device, such as a transducer array, includes a plurality of ultrasound transducers, each ultrasound transducer having a first electrode, a second electrode, a thin piezoelectric film located between the electrodes, and a substrate supporting the plurality of ultrasound transducers. In some examples, the electrode separation is less than 10 microns, facilitating lower voltage operation than conventional ultrasound transducers.
