  • Patent number: 8373306
    Abstract: An uninterruptible power supply (UPS) system that may incorporate a battery subsystem including at least one battery for generating electrical power, and a UPS subsystem including at least one power module. At least one first bus system may couple the battery subsystem to the UPS subsystem to supply electrical power to the UPS subsystem. An input and output (I/O) subsystem is in communication with an output of the UPS subsystem for generating an output signal. At least one second bus system may be used for coupling the output of the UPS subsystem to the I/O subsystem. At least one of the first and second bus systems may include a pair of parallel coupled, independent busses, and may further have a tie bar for enabling the pair of busses to be reconfigured as a single bus.

  • Publication number: 20110230730
    Abstract: A method or system is provided for diagnosing convulsions of a subject. The method or system may include two general components. First, a device or apparatus that measures and accumulates an electronic data stream representing the physical movements of the human limb(s) and presents that data to a suitable computational device or system for further processing. Second, a set of software or firmware algorithms that operates within the computational device on the data stream for the purpose of describing and characterizing the statistical properties of the movement signal during clinical seizure episodes. The system comprised of both components serves to distinguish and diagnose the movement features of ES events from those of PNES.

  • Patent number: 5484167
    Abstract: A label is formed onto packaging substrate and has a differential release coupon portion formed integrally therein. The packaging substrate is generally a label substrate such as a plastic, metal foil or paper as known in the art. The differential release coupon is defined by a tear outline consisting of a first arcuate section comprising a continuous radius cut; a second section comprising a plurality of overlapping, outwardly extending herringbone cuts defining a first taper; a third section comprising a plurality of straight cuts; a fourth section comprising overlapping vertical hash cuts defining a second taper; and transition cuts intermediate to the second and third sections and intermediate to the third and fourth sections. The tear pattern results in a coupon which is easily released in a single motion, and which leaves the remaining label intact, preserving valuable product information. The coupon is of a size and shape to facilitate redemption and handling by retail personnel.
