Abstract: A system and method for providing cardiac pulmonary nerve stimulation (CPNS) with therapy titration, a goodness indicator, and therapy weaning. Therapy titration can include using physiological measurements of contractility, lusitropy, and chronotropy to determine therapy efficacy and adjust therapy delivery. For example, the electrode position and stimulation intensity can be adjusted based on the physiological measurements. Therapy titration can include closed-loop therapy delivery, in which therapy is automatically adjusted based on the measured physiological parameters. A goodness indicator can be used to monitor cardiovascular parameters such as contractility, preload, lusitropy, systolic function, and/or chronotropy. The goodness indicator can determine whether the change in these parameters from nerve stimulation is positive, and further indicate optimal stimulation. Therapy weaning can include gradually reducing stimulation while ensuring no significant reduction in therapeutic efficacy ensues.

Abstract: A cable assembly is used to connect elements of a computing system. The cable assembly may include a first cable and a connector.

Further, the first cable includes an internal portion comprising a second conductor and a connector disposed on an end of the second conductor. However, the internal portion lacks an EMC shielding jacket for the second conductor. The external portion of the first cable and the internal portion of the first cable form a continuous cable. The connector device comprises a shield area configured to electrically couple with a chassis of a node of a computer system and a retainer configured to physically couple the cable assembly with the chassis.

Abstract: A cassette for insertion and removal of an edge-connected printed circuit card connectable to a server chassis is disclosed. The cassette includes a housing comprising a bottom wall having at least one elongated slot and a catch formed thereon. The cassette further includes a connector sub-assembly overlying the bottom wall having an edge connector socket formed thereon and configured to receive the edge-connected printed circuit card.

Abstract: The disclosure relates to systems and methods for cardiac rhythm management. In some cases, a system may include a pulse generator for generating pacing pulses for stimulating a heart of a patient; a memory; and a sensor configured to sense a response to an unwanted stimulation and to produce a corresponding sensor signal. A processing circuit may receive the sensor signal for a time after one or more pacing pulses, and may derive a time-frequency representation of the sensor signal based on the received sensor signal. The processing circuit may use the time-frequency representation of the sensor signal to help identify unwanted stimulation. Once unwanted stimulation is detected, the processing circuit may change the pacing pulses to help reduce or eliminate the unwanted stimulation.
