Patent number: 8721559Abstract: A system comprising a housing containing a signal generator coupled to an antenna and a dielectric material disposed about the antenna. The device is adapted to generate and direct a plurality of signals towards the heart of the person and measure a magnitude of a signal returned from the heart. The device further comprises a processor to compare differences between a magnitude of a signal propagated and the magnitude of the signal returned off the heart and determine a signal frequency having a maximum return loss value based on those differences. The processor also estimates a change in the amplitude of motion of a portion of a wall of the heart based on the differences between the magnitude of the signal propagated by the device and the magnitude of the signal returned off of the portion of the heart.Type: GrantFiled: January 5, 2009Date of Patent: May 13, 2014Assignee: Raytheon CompanyInventors: Stephen C.

Patent number: 6223075Abstract: The present invention provides methods and apparatus permitting rapid and thorough hydration of an initially dry hydratable matrix element contained within an iontophoretic bioelectrode. The apparatus of the invention comprises a bioelectrode system for iontophoretic delivery of medicaments having at least one hydratable matrix element and associated removable hydration assembly. The preferred embodiment of the present invention comprises two hydratable matrix elements each having an associated removable hydration assembly and each being associated with an electrical current distribution element. The removable hydration assembly includes an initially sealed liquid-storage component which maintains the desired hydrating liquid in isolation from the hydratable matrix element until such time as hydration is desired.Type: GrantFiled: December 9, 1996Date of Patent: April 24, 2001Assignee: Iomed, Inc.Inventors: Jon E.

Patent number: 6198394Abstract: A system for remotely monitoring personnel status includes a plurality of sensors disposable on a soldier or other person for developing signals which may be used to determine the physiologicalal status. The sensors communicate with a soldier unit which can process the information to ensure that the sensor data falls within acceptable ranges and communicate with remote monitors. The soldier unit also includes a global positioning system. By using the sensor data and the global positioning system, leaders and medics can quickly and accurately track and treat casualties in battle. The system enables more rapid location of the casualty, as well as remote triage/initial diagnosis, thereby assuring that those who are most in need of treatment are attended to first. Typically, the system monitors both body surface and ambient temperature, heart rate, shivering, motion status and body condition.Type: GrantFiled: December 5, 1996Date of Patent: March 6, 2001Inventors: Stephen C.

Patent number: 6165155Abstract: A low-profile multipathway automatic drug delivery system utilizing a battery powered control pad coupled to a disposable drug storage and delivery system and strapped to a patient's limb or torso. A preprogrammed or on-demand drug administration sequence is input to the control pad. When a drug is to be administered, the control pad ignites a high energy density propellant charge in the drug delivery system. Expanding propellant gas exerts pressure on a drug in a second chamber and forces it from the storage reservoir.Type: GrantFiled: January 16, 1999Date of Patent: December 26, 2000Assignee: Sarcos, LCInventors: Stephen C. Jacobsen, Roland Wyatt, Stephen C. Peterson, Tomasz J. Petelenz

Patent number: 6160478Abstract: A system for remotely monitoring a person's physical activity includes at least one accelerometer capable of measuring both the magnitude and direction of an acceleration. The acceleration data is processed to determine motion/position status and to decide whether there is a likelihood that the person has fallen, and if so, the likely direction that the person has fallen. Based on this data, the likely severity of the fall is calculated. If the severity of the fall is outside an acceptable limit, an alert state is reached upon which a signal is communicated to a remote monitoring unit. Likewise, various physiological conditions may be measured to determine the existence of any anomalous vital signs that would trigger an alarm state. If so, the remote monitoring unit will sound or otherwise communicate an alarm to a person associated with the remote monitoring unit.Type: GrantFiled: October 27, 1998Date of Patent: December 12, 2000Assignee: Sarcos LCInventors: Stephen C Jacobsen, Tomasz J. Petelenz, Stephen C. Peterson

Patent number: 6086562Abstract: An automatic injection device includes a drug-filled vessel having a flexible membrane over a first opening thereof and a puncturable seal in a wall thereof, a hollow needle attached at a first end to the flexible membrane and having a sharp end positioned proximate the puncturable seal housing. A pressure source such as a combustible propellant provides a compressed gas above the flexible membrane to force the membrane into the drug-filled vessel, forcing the hollow needle through the puncturable seal and the drug contained in the vessel through the hollow needle. After the drug has been substantially evacuated from the vessel, the membrane is allowed to return to its pre-expanded state thus retracting the hollow needle into the vessel. Preferably, the flexible membrane is an elastomeric material having a plurality of concentrically configured corrugations to allow expansion of the membrane into the vessel.Type: GrantFiled: October 1, 1998Date of Patent: July 11, 2000Assignee: Sarcos, Inc.Inventors: Stephen C. Jacobsen, Aaron M. Best, Tomasz J. Petelenz

Patent number: 6045534Abstract: An automated injection module is comprised of a housing, a piston drug capsule disposed within the housing, a piston core including a puncture seal membrane defining a reservoir for holding a drug between the puncture seal membrane and the piston drug capsule, an injection device having at least one sharp end for puncturing the puncture seal upon activation of the device, an end cap on a distal end of the housing, and a pressure source on a proximal end of the housing. The pressure source is preferably a propellant that ignites and forces the piston toward the distal end. Substantially simultaneously, the injection device pierces the puncture seal membrane, the piston core is forced into the piston drug capsule, and the drug is evacuated from the reservoir through the injection device and into a patient.Type: GrantFiled: October 27, 1997Date of Patent: April 4, 2000Assignee: Sarcos, Inc.Inventors: Stephen C.
