Abstract: A tri-wheel commuter device is convertible between a tricycle configuration and a three wheeled cart configuration. The tri-wheel commuter device has a pair of wheels, a drive wheel, a seat, a seat hanger, handlebars, at least one cupholder, and a basket assembly having left and right upper and lower baskets. The tri-wheel commuter device also has a first frame section, a second frame section, and a hinge, which allows for inline folding and unfolding of the tri-wheel commuter device between tricycle and three wheeled cart configurations. The configuration of the handlebars and the basket assembly allows for conversion.

Abstract: System and method for tracking and control in medical procedures. The system including a device that deploys fluorescent material on at least one of an organ under surgery and a surgical tool, a visual light source, a fluorescent light source corresponding to an excitation wavelength of the fluorescent material, an image acquisition and control element that controls the visual light source and the fluorescent light source, and captures and digitizes at least one of resulting visual images and fluorescent images, and an image-based, tracking module that applies image processing to the visual and fluorescent images, the image processing detecting fluorescent markers on at least one of the organ and the surgical tool.
