Abstract: Linoleic acid and related cardiolipin products are used as dietary supplements that provide cardiac benefits against a variety of cardiac related symptoms and diseases. For example, the disclosed compositions and methods may be used to treat or prevent hypertension, ischemic cardiomyopathy, heart disease, Barth Syndrome and heart failure.

Abstract: A system is provided for determining range to a wave energy source. The system includes a transmitter for transmitting a burst of pulses of wave energy in response to a trigger signal. A receiver is provided for determining a time of arrival of the burst and from such determined time of arrival, the range to the wave energy source. The receiver includes: an envelope detector for detecting an envelope of the burst; a network for producing an output in response to an early point on the detected envelope occurring prior to a peak in the detected envelope; a timer, responsive to the trigger signal and the network output for determining the time of arrival of the burst; and a processor, responsive to such determined time of arrival, for determining the range of the wave energy source from the transmitter.

Abstract: A ring communications network which is automatically reconfigured based on the detection of system defects.

Abstract: A ring communications system having a double ring format where the integrity of both rings is continuously checked, and where repair of the network is automatically accomplished upon the detection of the return to operation of a defective ring.

Abstract: The present disclosure describes a circuit arrangement wherein a clock signal generator generates two sets of time-period, separated enable signals and wherein there is controllable first direction current flow circuitry and controllable second direction current flow circuitry. One set of said enable signals is connected to said first circuitry to cause current flow in a first direction during a first period of time while the other set of said enable signals is connected to said second circuitry to cause current flow in a second direction during a second period of time which is separated from said first period by a predetermined period. The arrangement insures that the circuitry will not attempt to drive current in both directions at the same time.
