Patent number: 9674615Abstract: A linear moving coil magnetic drive system includes a continuous loop coil of flat, thin, rigid construction which levitates inside a quadrupole permanent magnet assembly with minimum gap. The linear coil may be a flat, racetrack-shaped, continuous loop, which may be constructed with single or multilayers PCB, flex-circuit, or other membrane process. The linear coil may include a coating of permeable magnetic material along the insulated conductor traces. The linear coil may be sandwiched between carbon fiber fabrics and cured to create a long, flat, thin and perfectly straight, extremely stiff, light-weight, load-bearing tee-shaped structure. This structure is levitated inside a quadrupole permanent magnetic assembly with minimum air gap between the high gauss magnets. In additional to the bare conductor traces inside this coil, also integrated into this PCB structure, is simple second-order equalizer electronic circuitry, comprised of surface-mounted resistors, capacitors, and IC chips.Type: GrantFiled: December 31, 2014Date of Patent: June 6, 2017Assignee: WALL AUDIO INC.Inventor: Chiko Fan

Publication number: 20080077802Abstract: Described herein are systems and methods that test authentication information on a fuel cartridge. A controller on a device that interfaces with the cartridge tests and validates the authentication information before permitting fuel provision from the cartridge. The authentication information can be used to prevent unauthorized cartridges from providing fuel. This permits the device to ensure that the cartridge, its manufacturer, and/or its contents are acceptable. Authentication information stored in a cartridge memory may also be encrypted.Type: ApplicationFiled: August 6, 2007Publication date: March 27, 2008Applicant: ULTRACELL CORPORATIONInventors: Robert Richardson, Ian Kaye, Chiko Fan, Theodore Prescop

Patent number: 6900059Abstract: An analytical device that can be used to conveniently and accurately assay plural vessels. In one exemplary embodiment, a pair of LED sources provides illumination through a pair of radial waveguides to plural vessels arranged in a pair of substantially concentric and circular rows about the LED sources. A light pipe receives light transmitted through a vessel from each radial waveguide and reflects the received light downward to a single printed circuit board that contains a photodiode for each light pipe, as well as processing circuitry. The first LED source/radial waveguide optical is used to confirm the presence of a vessel, and the second is used to perform, e.g., turbidometric and/or calorimetric assays upon an analyte within the vessel. The vessel is incubated in a vessel support that includes a heat conducting base and a heat insulating cover. Heat is supplied by a DC heater.Type: GrantFiled: November 27, 2000Date of Patent: May 31, 2005Assignee: Associates of Cape Cod, Inc.Inventors: Alan Shinn, Chiko Fan, Elias R. Elias, Thomas J. Novitsky, Michael Dawson, Keith Richardson
