Publication number: 20210162240Abstract: An image-guided radiotherapy system adapted to be juxtaposed adjacent a CT scanner comprises a frame having an orifice adapted to permit passage therethrough of a couch on which a patient is positioned, together with a gantry assembly rotatably mounted on the frame in which the gantry assembly comprises a shielding cylinder having an orifice therethrough in alignment with the orifice in the frame. The shielding cylinder has affixed thereto a linac-based treatment head configured to provide radiotherapy, and a beamstop positioned angularly opposite the treatment head to absorb radiation from the treatment head. The shielding cylinder provides sufficient shielding of radiation scattered from the patient and the remainder of the system to not require a conventional vault. In some embodiments an arch may be used instead of a cylinder.Type: ApplicationFiled: August 10, 2020Publication date: June 3, 2021Applicant: ETM Electromatic, Inc.Inventors: Georg WEIDLICH, William L. NIGHAN, Dennis DORE

Patent number: 9661734Abstract: A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of interleaved pulses having different energy levels, for example alternating 4 MeV and 6 MeV pulses or other energies where the difference in levels is at least approximately 1 MeV and less than approximately 5 MeV. The pulse repetition rate can be 100-400 pulses per second or more. In an embodiment, a cool down calculation is combined with automatic frequency control to provide stable energy and dose per pulse even upon restarting of pulsing after an “off” period of indeterminate duration.Type: GrantFiled: February 27, 2015Date of Patent: May 23, 2017Assignee: ETM Electromatic, Inc.Inventors: William L.

Patent number: 8625315Abstract: An inverter control is used to control the output of a distributed power generating station, such as a photovoltaic (PV) solar power station, connected to a power grid. The power station is connected to an inverter output. Pulse width modulation is used to shape the output in order to maximize power output within power quality parameters and provides control of a switching frequency of the inverter responsive to a sensed parameter. The technique allows an increase in output efficiency and provides for adjustment of power output to meet power quality parameters to an extent required in order to connect to the power grid.Type: GrantFiled: May 9, 2008Date of Patent: January 7, 2014Assignee: ETM Electromatic IncInventors: William L. Erdman, Jackson Moore

Patent number: 8401706Abstract: A group of solar power stations with inverters are adjusted in order to achieve optimum power output in accordance with maximum power-point tracking (MPPT). The MPPT data is used to perform adjustments. Power measurement factors, including Maximum Power Points (MPPs) are established to represent a bus-voltage setting that produces the maximum power output from an individual photovoltaic panel. These settings are established for the group so as to optimize power output under a variety of operating conditions.Type: GrantFiled: August 28, 2008Date of Patent: March 19, 2013Assignee: ETM ElectromaticInventors: Jackson Moore, William L. Erdman, Edward Robert Nelson

Patent number: 8295989Abstract: A power source affected by a geographically propagating condition (e.g. a weather-related condition) is monitored to detect changes in its power output. Characteristics of the monitored changes are analyzed to detect whether the changes are being caused by a geographically-propagating condition that could affect other power sources nearby. The information obtained from the measurements is used to extrapolate impending power-output changes in the same source, in one or more other sources, or in a collection of sources subject to effects of the propagating condition. The extrapolations enable one or more power generating systems associated with the source(s) to maintain the changes in its total power output within operating requirements.Type: GrantFiled: February 12, 2009Date of Patent: October 23, 2012Assignee: ETM Electromatic, Inc.Inventors: Philip Rettger, Marvin Keshner, Alexandra Katrina Pligavko, Jackson Moore, Bodo W.
