Abstract: Multiple wireless sensor assemblies are individually attached to standard biopotential electrodes, which are placeable on a subject's body at locations for biopotential signal recording. The sensor assemblies, which are electrically isolated, simultaneously measure potential voltages from the body sites in accordance with a synchronization. The measured signals are amplified, digitized, and filtered, and then sent wirelessly to a monitoring system. The monitoring system receives multiple sensor signals and constructs biopotential vectors depending on the placement and number of the sensors. The sensor signals are referenced to a common virtual center bias to synthesize a common mode rejection.

Abstract: High resolution full disclosure ECG data is transferred from a body sensor device to a handheld device via a wireless protocol. The handheld device transfers the full disclosure ECG data via a network to a center for analysis.

Abstract: A central server controls the receipt and analysis of patient medical data and patient information. The central server receives patient medical data and patient information from a sensor or a remote computer. A storage system of the central server stores the received patient medical data, patient information, and the associated medical report prepared by the analysis software on the central server after analysis of the patient medical data. The medical report associated with the patient medical data is transmitted from the central server to the remote computer. Also, a method controls the acquisition and analysis of patient medical data over a network by a central server from a remote computer operably interconnected by the network with the central server.

Abstract: High resolution full disclosure ECG data is transferred from a body sensor device to a handheld device via a wireless protocol. The handheld device transfers the full disclosure ECG data via a cellular network to a data center for analysis. A monitoring center communicating with the data center facilitates technician and physician review and interactions.

Abstract: A central server controls the receipt and analysis of patient medical data and patient information. The central server receives patient medical data and patient information from a remote computer. A storage system stores the received patient medical data, patient information, and the associated medical report prepared at analysis workstations at any location after analysis of the patient medical data. A processor controls access to and analysis of the patient medical data by analysis workstations and controls access to the medical report. The central server transmits the patient medical data to and receives the associated medical report from analysis workstations. The central server transmits the medical report associated with the patient medical data to the remote computer. Also, a method controls the acquisition and analysis of patient medical data over a network by a central server from a remote computer operably interconnected by the network with the central server.

Abstract: The invention is a central server configured to control the receipt and analysis of patient medical data and patient information. The central server controls access to the patient medical data by an analysis workstation that is responsive to a medical specialist. The analysis workstation analyzes the patient medical data and prepares a medical report associated with the patient medical data. The central server comprises a first communication interface for receiving patient medical data and patient information from a remote computer and for transmitting the medical report associated with the patient medical data to the remote computer. A storage system stores the received patient medical data, patient information, and the associated medical report. A processor is configured to control access to and analysis of the patient medical data by the analysis workstation and the medical specialist and is configured to control access to the medical report.

Abstract: A heat exchanger with an internal bypass valve wherein the open end of a bypass tube mounted within a heat exchanger tube forms a valve seat for the bypass valve. A valve head mounted on a valve rod is spring loaded against the valve seat in the preferred design. The length of the contact arms on the valve body controls the valve activation pressure. The heat exchanger tubes may be mounted in parallel and the bypass valves may be mounted in the same direction or in opposite directions to permit bidirectional bypass flow.
