Publication number: 20080077016Abstract: A system for monitoring physical properties of structures within animate and inanimate objects, including internal organs and bones of humans. The system includes sensing and readout devices. The sensing device is adapted to be implanted in a body and attached to a structure within the body, and includes an electrical circuit containing a first inductor coil formed at least in part by a conductor with portions thereof separated by gaps. The first inductor coil is adapted to be physically coupled to the structure so that changes in shape and size of the structure cause changes in shape and/or size of the first inductor coil and/or changes in the gaps, which alter the inductance of the first inductor coil when current flows through the electrical circuit. The readout device is not adapted to be implanted in the patient, and includes an inductor coil capable of electromagnetic telecommunication and/or electromagnetic powering of the sensing device.Type: ApplicationFiled: September 24, 2007Publication date: March 27, 2008Applicant: INTEGRATED SENSING SYSTEMS, INC.Inventors: Douglas Sparks, Nader Najafi

Publication number: 20070151335Abstract: A microfluidic device a micromachined freestanding member adapted to sense one or more properties of a fluid flowing through the freestanding member. The freestanding member is supported by a substrate and spaced apart and separated from the substrate to enable the freestanding member to move relative to the substrate under the influence of a vibration-inducing element. Movement of the freestanding member relative to the substrate is then sensed by a sensing element. The freestanding member has an inlet, an outlet, an internal passage that fluidically couples the inlet and outlet, and a wall that defines and separates first and second passage portions of the internal passage that are arranged in fluidic series so that a fluid flowing through the internal passage flows through the first and second passage portions in opposite directions.Type: ApplicationFiled: January 5, 2007Publication date: July 5, 2007Applicant: INTEGRATED SENSING SYSTEMS, INC.Inventors: Douglas Sparks, Nader Najafi

Publication number: 20060213552Abstract: A fluid system installed on a vehicle and a method for assessing a property of a fluid flowing in the fluid system. The fluid system and method entail flowing at least a portion of the fluid through a passage within a freestanding portion of a micromachined tube supported above a substrate so as to define a gap therebetween, vibrating the freestanding portion of the micromachined tube at a resonant frequency thereof, sensing the movement of the freestanding portion of the micromachined tube so as to measure at least one of the vibration frequency and deflection of the freestanding portion relative to the substrate and produce therefrom at least one output corresponding to at least one of the mass flow rate, specific gravity, and density of the portion of the fluid flowing through the passage, and then using the output to compute the property of the fluid.Type: ApplicationFiled: May 26, 2006Publication date: September 28, 2006Applicant: INTEGRATED SENSING SYSTEMS, INC.Inventors: Douglas Sparks, Nader Najafi

Publication number: 20060211981Abstract: A medical treatment procedure and system that makes use of a bidirectional flow sensor unit to monitor, detect, and control the flow of one or more fluids to and from a patient. The sensor unit measures both flow rate and flow direction of a fluid of a conduit through which a first fluid flows to or from the patient in a first direction, and through which it is possible that the first fluid or a second fluid may flow in a reverse direction through the conduit from or to, respectively, the patient. The sensor unit measures the flow rate of the first fluid as the first fluid flows through the bidirectional flow sensor unit, and senses if the first fluid or the second fluid flows through the bidirectional flow sensor unit in the reverse direction. A signal is relayed to indicate the occurrence of a reverse flow condition.Type: ApplicationFiled: December 27, 2005Publication date: September 21, 2006Applicant: INTEGRATED SENSING SYSTEMS, INC.Inventors: Douglas Sparks, Nader Najafi

Publication number: 20060175303Abstract: A process for producing a tube suitable for microfluidic devices. The process uses first and second wafers, each having a substantially uniform doping level. The first wafer has a first portion into which a channel is etched partially therethrough between second and third portions of the first wafer. The first wafer is then bonded to the second wafer so that a first portion of the second wafer overlies the first portion of the first wafer and encloses the channel to define a passage. The second wafer is then thinned so that the first portion thereof defines a thinned wall of the passage. Second and third portions of the second wafer and part of the second and third portions of the first wafer are then removed, and the thinned wall defined by the second wafer is bonded to a substrate such that the passage projects over a recess in the substrate surface. The second and third portions of the first wafer are then removed to define a tube with a freestanding portion.Type: ApplicationFiled: February 20, 2006Publication date: August 10, 2006Applicant: INTEGRATED SENSING SYSTEMS, INC.Inventors: Douglas Sparks, Nader Najafi
