  • Patent number: 6367975
    Abstract: A packaging web is disclosed. The web is an elongate, flattened plastic tube having face and back sides delineating the faces and backs of a set of side by side bags. The tube includes an elongated top section and spaced sets of side seals each extending transversely from the bottom to a location near the top section. The side seals of each set delineate sides of adjacent bags such that the sides and bottoms delineate the perimeters of a set of open top bags. The top section is essentially a bottom open tube for providing bag support when the web is fed into a bag loading machine. The web includes superposed, spaced lines of weakness in each of the face and back sides delineating tops of the bags. Each such spaced line of weakness extends substantially across an associated bag top and terminates in spaced relationship with an associate one of the spaced lines of weakness to leave solid sections in the face and back sides.

  • Patent number: 5804894
    Abstract: A low voltage battery pack monitoring circuit for a battery powered electronic device is disclosed. The circuit utilizes low battery and power failure set point voltages and first and second comparison circuits to compare voltage across the device battery pack to the set point voltages. If the battery pack output voltage falls below the low battery pack set point voltages, the first comparison circuit sends a signal to a microprocessor causing a low battery indicator light to be actuated. If the battery pack output voltage continues to decrease below the power failure set point voltage, the second comparison circuit includes a comparator which changes output state and turns off selected electronic systems of the device and the device enters a suspend mode. The low battery pack set point voltage value and the power failure set point voltage value are determined using an empirical look up table.
