  • Publication number: 20120022606
    Abstract: A system is disclosed wherein patient data, such as an electrocardiogram (“ECG”) signal or a chest impedance measurement signal, collected by a defibrillator device during a resuscitation event is analyzed and processed by a computing device to provide an assessment of CPR administered during the event. The CPR assessment results in one or more CPR figures of merit that relate to temporal characteristics of the CPR relative to the duration of the event. In one embodiment, the CPR figure of merit represents a percentage of the event period during which chest compressions were administered to the patient.

  • Patent number: 8090441
    Abstract: An external defibrillator is customized for at least one person, i.e., an anticipated patient, through creation of a profile for the anticipated patient that allows the defibrillator and users of the defibrillator to provide customized treatment to the patient. The profile may include treatment parameters for the anticipated patient, such as defibrillation therapy parameters selected for the patient. The profile may also include a baseline recording of a physiological parameter of the patient, and medical history and personal information regarding the patient. In some embodiments, the external defibrillator stores a profile for each of one or more anticipated patients within a memory. In other embodiments, a profile for an anticipated patient is stored within a medium associated with that anticipated patient. The medium may, for example, be a removable medium for external defibrillators.

  • Patent number: 8069355
    Abstract: A data path controller, a computer device, an apparatus and a method are disclosed for integrating power management functions into a data path controller to manage power consumed by processors and peripheral devices. By embedding power management within the data path controller, the data path controller can advantageously modify its criteria in-situ so that it can adapt its power management actions in response to changes in processors and peripheral devices. In addition, the data path controller includes a power-managing interface that provides power-monitoring ports for monitoring and/or quantifying power consumption of various components. In one embodiment, the data path controller includes a power-monitoring interface for selectably monitoring power of a component.

  • Patent number: 7913338
    Abstract: A pad (10) of interleaving linear cells (2) has loop straps (1) to hold the central section of the cells (2) linearly in parallel with the cell axis (11), whilst the opposite ends (3) of each cell (2) are secured a pre-determined distance (4) off-set from the cell axis (11). The distance (4) can vary along the length of the pad. By fixing of the ends (3) of the cells (2) at a distance (4) away from the cell axis, each end (3) of the cell (2) is pulled away from the centre axis of the cell, the loop straps (1) and the cell (2) become tensioned, preventing the central cell section from moving or rotating. The resulting cell has been seen to dramatically reduce the movement of a user along the pad with improved user comfort and enhanced pressure relief.

  • Patent number: 7779191
    Abstract: A system and method for transitions a computing system between operating modes that have different power consumption characteristics. When a system management unit (SMU) determines that the computing system is in a low activity state, the SMU transitions the central processing unit (CPU) into a low power operating mode after the CPU stores critical operating state of the CPU in a memory. The SMU then intercepts and processes interrupts intended for the CPU, modifying a copy of the critical operating state. This effectively extends the time during which the CPU stays in lower power mode. When the SMU determines that the computing system exits a low activity state, the copy of the critical operating state is stored in the memory and the SMU transitions the CPU into a high power operating mode using the modified critical operating state.

  • Publication number: 20080047717
    Abstract: One or more flapper valve assemblies are placed in a casing string extending through one or more hydrocarbon bearing intervals. The flapper valve assemblies are placed between some of the hydrocarbon bearing intervals. In an open or inoperative position, the flapper valve assemblies are full opening compared to the casing string. The hydrocarbon bearing intervals are stimulated, typically by fracing, starting with the bottom zone. The flapper valve assembly immediately above the stimulated interval is manipulated to allow it to close, preventing downward flow in the well and thereby isolating the lower stimulated interval so an upper interval can be stimulated. The well is easy to put on production because the flapper valves will normally open simply by opening the well at the surface.

  • Patent number: 7302512
    Abstract: A computer device, an input/output (“I/O”) communication subsystem, a chipset and a method are disclosed for implementing interrupt message packets to facilitate peer-to-peer communications between a device controller and a coprocessor. Advantageously, the various embodiments of the invention obviate a requirement for specialized circuitry on a motherboard to establish peer-to-peer communications. In one embodiment, an I/O communication subsystem includes a bus interface for coupling the I/O communication subsystem to a general-purpose bus. It also includes a device controller being configured to generate an interrupt as an interrupt message packet for a coprocessor, which, in turn, interrupts processing functions that otherwise are performed by the host processor. The device controller can reside either internal or external to the I/O communication subsystem.
