Abstract: A beam profile measurement detector is a tool to efficiently verify dose distributions created with active methods of a clinical proton beam delivery. A Multi-Pad Ionization Chamber (MPIC) has 128 ionization chambers arranged in one plane and measure lateral profiles in fields up to 38 cm in diameter. The MPIC pads have a 5 mm pitch for fields up to 20 cm in diameter and a 7 mm pitch for larger fields, providing an accuracy of field size determination of about 0.5 mm. The Multi-Layer Ionization Chamber (MLIC) detector contains 122 small-volume ionization chambers stacked at a 1.82 mm step (water-equivalent) for depth-dose profile measurements. The MLIC detector can measure profiles up to 20 cm in depth, and determine the 80% distal dose fall-off with about 0.1 mm precision. Both detectors can be connected to the same set of electronics modules, which form the detectors' data acquisition system.

Abstract: A bag is has an opening defined by a pair of walls and a pair of gussets. The walls are joined by the gussets. The bag has two slits. Each of the two slits is formed adjacent a wall and a gusset. Each of the two slits is adjacent the opening. A zipper comprises a pair of interlocking sections. The zipper is inserted through the slits. The interlocking sections are secured to at least a portion of each of the walls.

Abstract: A method is presented which uses Augmented Reality for visualization of text and other messages sent to an EFR by an incident commander. The messages are transmitted by the incident commander via a computer at the scene to an EFR/trainee in an operational or training scenario. Messages to an EFR/trainee, including (but not limited to) iconic representation of hazards, victims, structural data, environmental conditions, and exit directions/locations, are superimposed right onto an EFR/trainee's view of the real emergency/fire and structural surroundings. The primary intended applications are for improved safety for the EFR, and improved EFR-incident commander communications both on-scene and in training scenarios.
