20080251077WIRELESS MEDICAL GASES MANAGEMENT SYSTEM - The present invention generally provides methods and systems for managing a medical gas system by using wireless sensors located at the point of use. In one embodiment, a wireless sensor is fixed to a gas outlet, and is configured to measure gas flow, and to detect whether the gas outlet is connected to a medical device. The gas flow and connection data is included in a wireless signal that is transmitted to a remote server. The data received by the server may be analyzed to determine if any local or system leaks are occurring. In addition, the data may be used to monitor patient therapies, to calculate costs, and to determine replenishment points.10-16-2008

20090011403MICROPOROUS MATERIALS, METHODS OF MAKING, USING, AND ARTICLES THEREOF - Described herein are methods for separating one or more analytes present in a fluid sample. The methods involve passing the fluid through or into a microporous material, wherein the analytes are localized near the surface of the microporous material. Additional processing steps such as hybridization and amplification can be performed once the analyte is localized. In one method, once the analyte is localized, the analyte can be detected, counted, and correlated in order to determine the concentration of the analyte in the sample. In another method, the localized analyte is destabilized to make the localized analyte more accessible for chemical manipulation. Modified microporous materials and composite materials are also disclosed that can be used in any of the methods and articles described herein. The composite is composed of a microporous material and a pigment, wherein the pigment is incorporated in the microporous material. The pigments alter the optical properties of the microporous material, which enhances the detection of analyte once it is localized. Methods for making pigmented composites are also disclosed. In a further aspect, various kits and articles such as filtration devices containing any of the microporous materials described herein are provided.01-08-2009

20080266152Digital radio frequency memory - A digital radio frequency memory (DFRM) which converts an incoming analog radio frequency signal to a fourteen bit digital signal allowing for digital signal processing and then retransmitted as an analog RF signal. The DFRM provides a time delay for RF signals by storing the signal. The DFRM also changes the signal frequency in the range of plus or minus 100,000 KHz which places a doppler on the signal. The signal phase is changed in a range of 0 to 359 degrees by the DFRM.10-30-2008

20080304976TEMPERATURE MANAGEMENT FOR ELECTRIC MOTOR DRIVEN PUMP - A hydraulic pump system is provided that includes a pump driven by an electric motor. The electric motor includes windings that receive power from a power source. In one example, a temperature sensor is arranged in proximity to hydraulic fluid associated with the pump, such as at an input of the pump. In another example, the temperature sensor measures the ambient temperature to predict the viscosity of the pump based upon cool down rates of the system. A controller monitors a temperature at the temperature sensor and commands power to be provided to the windings to generate heat. Electric motor power consumption can be monitored to determine viscosity. The heat reduces the viscosity of the hydraulic fluid. Bleed air may be selectively provided to a casing associated with the hydraulic fluid in response to a command from the controller. The controller actuates a valve to regulate the flow of bleed air to the casing to provide supplemental heat to the heat provided by the windings. In this manner, the viscosity of the hydraulic fluid is more efficiently managed to provide desired startup of the pump in cold conditions.12-11-2008
