Multi-Source Autonomous Response for Targeting and Monitoring of Volcanic Activity

This concept has great relevance to Earth science and future planetary exploration. The study of volcanoes is important for both purely scientific and human survival reasons. From a scientific standpoint, volcanic gas and ash emissions contribute significantly to the terrestrial atmosphere. Ash depositions and lava flows can also greatly affect local environments. From a human survival standpoint, many people live within the reach of active volcanoes, and therefore can be endangered by both atmospheric (ash, debris) toxicity and lava flow.

Software Suite to Support In-Flight Characterization of Remote Sensing Systems

A characterization software suite was developed to facilitate NASA’s in-flight characterization of commercial remote sensing systems. Characterization of aerial and satellite systems requires knowledge of ground characteristics, or ground truth. This information is typically obtained with instruments taking measurements prior to or during a remote sensing system overpass. Acquired ground-truth data, which can consist of hundreds of measurements with different data formats, must be processed before it can be used in the characterization. Accurate in-flight characterization of remote sensing systems relies on multiple field data acquisitions that are efficiently processed, with minimal error.

Visual Image Sensor Organ Replacement

This innovation is a system that augments human vision through a technique called “Sensing Super-position” using a Visual Instrument Sensory Organ Replacement (VISOR) device. The VISOR device translates visual and other sensors (i.e., thermal) into sounds to enable very difficult sensing tasks.

Integrating Force Sensors into Robotic Surgery

Force sensing resistors provide tactile feedback during robotic surgery. Due to advances in electronics and technology, robotic surgery has become increasingly popular. Surgeons no longer have to operate directly on a patient, but instead can control a robot to carry out the procedure. Robotic surgery has benefits to both the surgeon and the patient. For the surgeon, robots display 3D visualization for enhanced viewing of the operative area and improve the control, precision, and range of motion of smaller instruments. While robotic surgery may seem like the future of the medical industry, it still has obstacles to overcome. One significant disadvantage to robotic surgery is the lack of haptic technology, which provides physical sensations that enable electronics to give their users force feedback.
