Patent number: 7403783Abstract: The present invention relates to a method of determining the location of a target. The method includes initializing a set of base stations to determine their location relative to each other. At the target, the time of arrival of at least one signal from each of the plurality of base stations Is measured. From this, the location of the target relative to the plurality of base stations may be directly calculated using a closed solution. In one embodiment, a time of arrival technique is used and in another embodiment a time difference of arrival technique is used. Preferably an ultra-wide band frequency is utilized.Type: GrantFiled: February 17, 2005Date of Patent: July 22, 2008Assignee: Jadi, Inc.Inventors: Ka C. Cheok, G. Edzko Smid

Publication number: 20060188399Abstract: A piezoelectric analytical sensor system is provided that includes a piezoelectric crystal having a sensing surface. The piezoelectric crystal is driven at a base oscillation frequency that is responsive to an analyte interacting with the sensing surface of the crystal. A crystal resonator in mechanical communication with the crystal drives the crystal at the base oscillation frequency. An electronic circuit is provided for measuring a vibrational frequency of the crystal and relating the vibrational frequency to a quantity of the analyte in contact with the sensing surface of the piezoelectric crystal. A modular interface in electrical communication with the electronic circuit is provided to engage an electronic device and derive power from that electronic device.Type: ApplicationFiled: February 3, 2006Publication date: August 24, 2006Applicant: JADI, Inc.Inventor: G.
