Publication number: 20140033990Abstract: A remotely activated reward dispenser. The remote dispenser delivers consumable rewards in response to a trigger signal from a remote triggering device. The reward dispenser uses a two stage delivery system to prevent unintentional release of the consumable reward. A vibration stage moves a portion of the consumable reward from a reservoir to a staging platform without crushing the consumable reward. The second stage transfers the consumable reward from the staging platform to an area accessible by the animal. A vibration damping system reduces the noise generated by the reward dispenser. An adjustable transition varies the feed rate for the consumable reward.Type: ApplicationFiled: August 6, 2013Publication date: February 6, 2014Applicant: Radio Systems CorporationInventors: Jeffrey Brown, Steven Schrick, Matthew Strong, John Rowlands

Patent number: 7323692Abstract: The present invention is an indirect AMFPI wherein a phosphor such as a structured cesium iodide (CsI) is used to convert x-ray energy to optical photons or a charge, which is then detected by a two-dimensional array of either thin-film transistors (TFTs) such as an amorphous a-Se TFTs or a photodiode array. A scanning control circuit generates pulses to turn on the TFTs one row at a time, and thus the charge in the individual arrays is transferred from the TFT to one or more external charge-sensitive amplifiers. The charge-sensitive amplifiers are shared by all the pixels in the same column. The two-dimensional array can be read in real time.Type: GrantFiled: August 10, 2005Date of Patent: January 29, 2008Assignees: Research Foundation of State University of New York, Sunnybrook and Woman's College Health Sciences CenterInventors: John A.

Patent number: 7297914Abstract: The present invention provides a practical design of a megavoltage x-ray detector with both high quantum efficiency (QE) and high resolution. The x-ray detector includes an optical-fiber taper (OFT) made from a large number of optical fibers, each of which is aligned with the incident x-rays from an x-ray source hitting a top surface of the optical fiber taper. The optical-fiber taper is a matrix of optical fibers with the core material made of, e.g., silica and coated with a cladding glass or polymer such that light created within the core of each optical fiber will be guided to the bottom ends of the fiber with the ends of the fibers at the bottom being optically coupled to and optical image read-out device. Each optical fiber in the optical fiber taper is fully aligned with the incident x-ray source so that x-rays entering the top of the fiber travel directly towards the bottom of the same fiber.Type: GrantFiled: January 4, 2007Date of Patent: November 20, 2007Assignee: Sunnybrook Health Sciences CentreInventors: Geordi G.

Publication number: 20070201616Abstract: The present invention provides a digital x-ray radiographic imaging system. The system is based on a photoconductive detector and an electro-optic light modulator, where the photoconductive detector layer absorbs x-rays that have passed through an object to form an exposure of the object. The absorbed x-rays create a static optical image, which is stored in the electro-optic light modulator, allowing the capture of the optical image to continue over longer time. The optical image is digitized using a scanning system and an external light source. The image is then processed and stored by a computer. After the optical image is recorded, an erasing mechanism is used to reset the system before a new exposure is made.Type: ApplicationFiled: February 9, 2007Publication date: August 30, 2007Inventors: John Rowlands, Christie Webster, Ivaylo Koprinarov, Peter Oakham, Stephen Germann, James Stiles
