Patent number: 7999226Abstract: A portable infrared sensor and speaker assembly is described which, in one form, includes an elongated array of infrared sensors along respective first and second side portions of a speaker. Infrared reflective surfaces, which may include a portion of the side surface of the speaker, enhance the detection of infrared signals by the sensors. This technology can be used, for example, in infrared signal amplification systems for amplifying a speaker's voice in a classroom or auditorium.Type: GrantFiled: May 25, 2007Date of Patent: August 16, 2011Assignee: Lightspeed Technologies, Inc.Inventors: Thomas J.

Patent number: 6438208Abstract: A window and cooling plenum for use with x-ray devices. The x-ray device includes an x-ray tube at least partially immersed in coolant contained within a reservoir. The coolant is continuously circulated through the reservoir by an external cooling unit. The window is brazed into a vacuum enclosure of the x-ray tube and includes a plurality of extended surfaces that are integral with the window. A compensating window is also provided and is disposed substantially proximate to the extended surfaces of the window so that a fluid passageway is defined. The compensating window and window are substantially enclosed within a cooling plenum having fluid inlet and outlet connections in fluid communication with the fluid passageway and the reservoir. A flow of coolant generated by the external cooling unit enters the fluid passageway so that the coolant is able to absorb heat dissipated by the window. Upon exiting the fluid passageway, the coolant returns to the reservoir to repeat the cycle.Type: GrantFiled: September 8, 2000Date of Patent: August 20, 2002Assignee: Varian Medical Systems, Inc.Inventor: Thomas J. Koller

Patent number: 6060100Abstract: A pet chew treat made from the gastro-intestinal organs of a bison wherein the gastro-intestinal organs are cleaned of any fat, cut into strips, arranged on a drying rack, smoked in a smokehouse at preferably about 110.degree. F., and then maintained at a temperature of preferably between about 110.degree. F. and about 150.degree. F. until the strips reach about 2% to about 20% moisture. The resulting chew treat is not human food grade and is preserved so that it can be stored at room temperature without a danger of spoilage.Type: GrantFiled: January 5, 1999Date of Patent: May 9, 2000Inventor: Thomas J. Koller

Patent number: 4969172Abstract: An x-ray tube rotor structure wherein a target support stem has an externally threaded end portion engaged with an internally threaded surface of an encircling bushing and fixedly attached thereto by an interposed brazed joint. The stem is made of predominantly molybdenum material having a linear thermal expansion coefficient of 58.times.10.sup.-7 per degree Fahrenheit and is thermally matched with the bushing which is made of an iron cobalt nickel alloy material having a linear thermal expansion coefficient of 60.times.10.sup.-7 per degree Fahrenheit. The bushing has an outer surface fixedly attached through a welded joint with an inner surface of an annular plug which has an outer marginal portion fixedly attached to an adjacent end portion of a coaxial rotor skirt. The annular plug is made of an iron chrome nickel alloy material having a linear thermal expansion coefficient of 84.times.10.sup.Type: GrantFiled: August 15, 1988Date of Patent: November 6, 1990Assignee: Machlett Labs. Inc.Inventors: Albert F. Fengler, Raymond A. Daly, Ming-Wei P. Xu, Steven Tavoletti, Thomas J. Koller

Patent number: 4767961Abstract: An X-ray generator system comprising a pressurized fluid source disposed for directing dielectric coolant fluid through a housing wherein an X-ray source may be electrically connected for generating X-rays, the system including a venturi device having a restricted passage through which the fluid flows and which is disposed in communication with portions of the housing where gas bubbles may accumulate in the fluid. Thus, the fluid flowing through the restricted passage of the venturi device produces a reduction in pressure which draws fluid from said portions of the housing so that any gas bubbles accumulated therein may be purged from the system.Type: GrantFiled: October 3, 1983Date of Patent: August 30, 1988Assignee: The Machlett Laboratories, Inc.Inventors: Thomas J. Koller, John D. Weaver, Sr.

Patent number: 4736400Abstract: A rotatable x-ray target assembly and process for manufacturing the same is provided for an x-ray tube. The x-ray target assembly comprises an x-ray target member having an opening disposed therethrough and a support member having: a mounting surface disposed transversely to the axis of rotation, a lower surface of the target member being disposed on the mounting surface; and, a threaded stem extending from said mounting surface through the opening of the target member. The support member also comprises a nut adapted to receive the threaded stem, the nut engaging an upper surface of the target member. The target member is secured to the support member by brazing material disposed between the lower surface of the target member and the mounting surface, a first portion of the brazing material being diffused into the target member and a second portion of the brazing material being diffused into the mounting surface of the support member.Type: GrantFiled: January 9, 1986Date of Patent: April 5, 1988Assignee: The Machlett Laboratories, Inc.Inventors: Thomas J. Koller, Steven Tavoletti

Patent number: 4611777Abstract: A stand for a computer display terminal is described which enables the terminal to be tilted in a vertical direction, swiveled in a horizontal plane and adjusted in height. The height adjustment is accomplished by a pair of telescoping posts attached between a swivel base member and tilt carriage arms on opposite sides of the computer terminal. A gas cylinder is provided to counterbalance the weight of the terminal and is connected to the telescoping posts by flexible connectors, such as metal cables. As a result, the user adjusts the height by merely overcoming the friction of the telescoping posts the pulley system and the gas spring since the weight of the computer terminal is counterbalanced by the gas cylinder. A releasable brake is provided on the base member which also includes a glide means for enabling gliding movement of the stand over a support surface only when the brake means is released.Type: GrantFiled: October 15, 1984Date of Patent: September 16, 1986Assignee: Tektronix, Inc.Inventors: Thomas M. Ireland, Thomas J. Koller, Michael T. Lancaster

Patent number: 4511235Abstract: A paper loading mechanism for a copier or the like is disclosed. A paper guide member and a foam pressure roller rotatably coupled to a paper drive roller feeds a web of paper to the drive roller, thereby semi-automatically feeding the paper along a predetermined path. A paper canister, having the webs of paper disposed therein, is affixed to a front cover of said paper loading mechanism. This structural arrangement simplifies the procedure of loading paper into the paper loading mechanism of the present invention.Type: GrantFiled: December 6, 1982Date of Patent: April 16, 1985Assignee: Tektronix, Inc.Inventor: Thomas J. Koller
