Multi-cell battery packs can be made safer with certain features that mitigate the consequences of cell failure. Parameters of a cell are monitored to determine when the cell should be disconnected from the pack in case of a fault. The battery is reconfigured to continue operating in a safer mode. An over-charging prevention system reduces the maximum voltage that remaining battery pack can be charged to, so that the cells do not overcharge. Additional circuitry allows the disconnected cell to be periodically reconnected to the battery pack to determine if its conditions have sufficiently improved. The cells also include components for self-powering these cell functions while it is disconnected from the rest of the circuit.

Medical dressings are provided that minimize the disruptive forces directed at the device-skin interface during the processes of dressing changes. The instantaneous disruptive force, imparted to a healing skin wound by an adhesive dressing as it is being de-adhesed from the vicinity of the skin wound, is determined, in part, by the yield strength (force/unit area) of the adhesive/skin interface and, in part, by that portion of surface area (area) of skin-dressing adhesion participating in traction of the skin at said instant. A method to minimize the disruptive force of a medical dressing is to reduce the surface area of skin-dressing adhesion being de-adhesed at a specific instant by dividing the total surface area of skin-dressing into substantially smaller subareas, each of which, when being de-adhesed, would impart disruptive forces to the healing skin wound which are smaller than the tensile strength of the skin wound. 1.

Steady flow hydrodynamic performance testing is performed on a valved prosthesis mounted in a test conduit. The system is configured with prescribed test condition inputs into control software. Upon test initiation, a steady flow pump is activated and automatically adjusts its flow based on the software logic to meet the prescribed first test condition. During forward flow pressure drop testing, the flow pump is automatically adjusted to achieve and hold a particular flow rate. During back flow leakage testing, the steady flow pump is automatically adjusted to achieve and hold a particular differential pressure across the test prosthesis while a flow rate of the leakage flow is measured. After a first test condition has been achieved, the system control software then automatically adjusts the pump flow rate to meet a second test condition. This process then continues until all conditions set by software inputs are evaluated. 1.
