20120126829 | METHODS AND SYSTEMS FOR MONITORING COMPONENTS USING A MICROWAVE EMITTER - A method for measuring a proximity of a component with respect to a microwave emitter is provided. The method comprises transmitting at least one microwave signal to the microwave emitter. At least one electromagnetic field is generated by the microwave emitter from the microwave signal. Moreover, the method comprises inducing a loading to the microwave emitter by an interaction between the component and the electromagnetic field, wherein at least one detuned loading signal representative of the loading is reflected within a data conduit from the microwave emitter. The detuned loading signal is received by at least one signal processing device. The signal processing device then measures the proximity of the component with respect to the microwave emitter based on the loading signal. An electrical output is generated by the signal processing device. | 05-24-2012 |
20130137378 | METHOD FOR REDUCING POWER CONSUMPTION IN NODE DEVICES OF A CONDITION MONITORING SYSTEM - This disclosure describes examples of condition monitoring systems with node devices that can adjust the power level of a radio. Embodiments of the node device can dynamically vary the power level for the radio in response to communication with other node devices. In one example, the node devices measure the strength of a signal received from the other node devices. The node devices can, in response to this value, vary the power level of the radio to optimize power consumption and extend the battery life for the node device. | 05-30-2013 |

20090071911 | Safety Vent Structure for Extracorporeal Circuit - A vent assembly is described for use in an extracorporeal fluid unit. A vent structure adjacent to a micro-porous membrane forms the assembly. The vent structure is porous, but expands when the vent structure becomes wet, thereby closing off the pores and inhibiting (e.g., preventing) fluid from flowing through the vent structure. The vent structure also protects the membrane from becoming wet, such as from condensation. | 03-19-2009 |
