  • Internally mounted collimators for stereotactic radiosurgery and stereotactic radiotherapy
    Patent number: 8890100
    Abstract: A beam filter positioning device includes a first and a second axes operable to move a body supporting one or more collimators, one or more photon flattening filters, one or more electron foils, and field light mirror etc. The collimators may be configured to collimate radiation to define a treatment beam suitable for radiosurgery. A controller is programmed to control the servo motor of the first and second axes to accurately position the beam filters. Radiation apparatuses and systems incorporating the beam filter positioning device or assembly are also provided.

  • System and method for facilitating electronic commerce transactions at an automatic teller machine
    Patent number: 7546274
    Abstract: A method and system facilitate an electronic commerce transaction between an ATM and an electronic commerce merchant via a global communications network. Transaction data is received at a server and verified with a processing network. The transaction data is reformatted, such that the data can be utilized by a server located on a global communications network, and transmitted over the global communications network to the servers of an electronic commerce merchant. Data is then received from the merchant, reformatted into a format that is capable of being utilized by the ATM, and transmitted back to the ATM.
