Abstract: Improved methods and systems for automated, self-service issuing of a card or other object to an individual. The system can include a self-service issuing machine that is configured to issue a card or object to a user, allow return of the card or object back into the machine, and later reissuing of the card or object to the same or different user. The machine can be used in a number of applications, including with an access control system that controls access into and throughout a building(s). The machine can be configured to dispense temporary re-usable badges to employees, contractors, and visitors. The badges can be returned to the machine, which stores the returned badges for later re-issuance to a later user needing a temporary badge. The machine can also integrate with an enterprise access control system that controls access to a number of dispersed building sites.

Abstract: A system and method is disclosed for radiation dose calculation within sub-volumes of a particle transport grid. In a first step of the method voxel volumes enclosing a first portion of the target mass are received. A second step in the method defines dosel volumes which enclose a second portion of the target mass and overlap the first portion. A third step in the method calculates common volumes between the dosel volumes and the voxel volumes. A fourth step in the method identifies locations in the target mass of energy deposits. And, a fifth step in the method calculates radiation doses received by the target mass within the dosel volumes.

Abstract: The Evaluated Teletherapy Source Library (ETSL) is a system of hardware and software that provides for maintenance of a library of useful phase space descriptions (PSDs) of teletherapy sources used in radiation therapy for cancer treatment. The PSDs are designed to be used by PEREGRINE, the all-particle Monte Carlo dose calculation system. ETSL also stores other relevant information such as monitor unit factors (MUFs) for use with the PSDs, results of PEREGRINE calculations using the PSDs, clinical calibration measurements, and geometry descriptions sufficient for calculational purposes. Not all of this information is directly needed by PEREGRINE. It also is capable of acting as a repository for the Monte Carlo simulation history files from which the generic PSDs are derived.
