20120179045 | Fetal Scalp Doppler Device and System - A fetal pulse monitor includes an ultrasound crystal. An ultrasound controller is electrically connected to the ultrasound crystal and operates the ultrasound crystal to produce ultrasound signals and receive reflected ultrasound signals. A wireless transmitter is electrically connected to the ultrasound controller. A biocompatible housing at least partially surrounds the ultrasound crystal, ultrasound controller, and the wireless transmitter. A system for monitoring fetal heart rate includes a fetal pulse monitor configured for insertion into a womb of a patient and for attachment to a fetus within the womb. The fetal pulse monitor includes an ultrasound crystal, an ultrasound controller electrically connected to the ultrasound crystal, and a wireless transmitter electrically connected to the ultrasound controller. A patient monitoring device is external to the womb and includes a wireless receiver and a processor that detects instantaneous fetal heart rate from the received ultrasound signal. A graphical display is communicatively connected to the patient monitoring device. The graphical display is operated by the patient monitoring device to present the determined fetal heart rate. | 07-12-2012 |
20120123995 | POWER CONSUMPTION COMPLIANCE MONITORING SYSTEM AND METHOD - Systems and methods for monitoring compliance with a request not to run a type of load (e.g., a high-power-consuming appliance) during a demand response event are provided. One such system may include storage containing a load profile representative of a pattern of power consumption by a type of load and data processing circuitry. The data processing circuitry may compare a power usage profile representing power consumption by a consumer at least over a period of time to the load profile to determine whether the consumer is running the type of load over the period of time. | 05-17-2012 |

A phase change material is disposed around an external surface of the combined cycle power generation system component. | 07-07-2011 |
20090076354 | COMPENSATION OF HUMAN VARIABILITY IN PULSE OXIMETRY - The invention relates to a method of calibrating a pulse oximeter, in which the effects caused by tissue of a subject can be taken into account. A detector output signal is measured when living tissue of the subject is present between emitters and the detector in a sensor. Nominal calibration and nominal calibration characteristics are read from a memory, whereupon values for the same nominal characteristics for the sensor on living tissue of the subject are established using the detector output signal. Then, changes in the nominal calibration characteristics induced by the living tissue are calculated and a subject-specific calibration is formed by correcting the nominal calibration with the changes. Finally, the hemoglobin fractions are solved using the corrected nominal calibration. The invention also relates to a pulse oximeter having pre-stored data in a memory comprising data of initial characterization measurements, data of nominal characteristics describing calibration conditions under which a predetermined calibration of the apparatus has been applied, and data of nominal calibration and nominal calibration characteristics. An extinction coefficient compensation block is operatively connected to the first signal processing means and to the memory for reading data, said block comprising first calculation means adapted to correct the nominal characteristics of the sensor on living tissue of the subject. A transformation compensation block is operatively connected to the first signal processing means for receiving the DC signals and to the memory for reading data, said block comprising second calculation means adapted to correct the transformation values based on the changes in the DC signals induced by tissue of the subject. Alternatively, said data may be stored in the sensor part of the pulse oximeter. | 03-19-2009 |
