Abstract: Described is a portable recorder for use by first-response emergency service personnel while providing care to a human subject. The recorder includes memory for storing data and sensor circuitry for sensing physiological signals through electrodes attached to a human subject and for converting the physiological signals into electrical signals. The recorder also has a transducer for converting sound waves into electrical signals and analog-to-digital converter circuitry for converting the electrical signals corresponding to the physiological signals and the electrical signals corresponding to the sound waves into digital data. A processing unit stores the digital data corresponding to the sound waves and the digital data corresponding to the physiological signals in the memory. The data stored in the memory are transferred to a remote computing system. An application program on that computing system automatically generates a report based on the data transferred from the memory.

Abstract: A heating system includes a first fluid circulation system having tubing for conveying fluid, a pump for moving the fluid through the tubing of the first fluid circulation system, and a microwave system that heats the fluid passing through the tubing. The amount of fluid circulating in the first fluid circulation system approximates less than a gallon. A second fluid circulation system has tubing for conveying fluid and a pump for moving this fluid through the tubing of the second fluid circulation system. A heat exchanger, connected to the tubing of the first fluid circulation system and to the tubing of the second fluid circulation system, the heat exchanger transfers heat from the fluid in the first fluid circulation system to the fluid in the second fluid circulation system.

Abstract: A cost-effective, lightweight, durable, and high-quality Holter cardiac monitor with extensions enabling a single device to also provide loop recorder and event recorder functions. The system provides near real-time patient monitoring, twenty-four hours a day, seven days a week, anytime, anywhere, and is always ON. The patient worn device is one component of a complete system. The device portion of the system combines ease of use, excellent battery life, low cost, and the best features of telementry, Holter recorders, and event/loop recorders while eliminating the hassles of hookup, lost/overwritten data, and user intervention required to send in data.
