  • Publication number: 20080115638
    Abstract: A cutter-sealer (10) and a method (300) for cutting and sealing layers of film (70) together. The cutter-sealer (10) provides a heated blade (20), part of which moves through sheets of tautly held layers of film (70) into a slot defined by the seal pad (40). The blade's (20) motion is arrested by a set of blade shoulders (26) that press against the layers of film (70) for a period of time, thereby sealing the layers of film (70) together. The method (300) provides a means of cutting layers of film (70) without liquefaction and a means of sealing the newly cut edges of the layers of film (70) together, also without liquefaction of the layers of film (70).

  • Publication number: 20060060041
    Abstract: A cutter-sealer (10) and a method (300) for cutting and sealing target materials (70) together. The cutter-sealer (10) provides a heated blade (20), part of which moves through sheets of tautly held target materials (70) into a slot defined by the seal pad (40). The blade's (20) motion is arrested by a set of blade shoulders (26) that press against the target materials (70) for a period of time, thereby sealing the sheets of target materials (70) together. The method (300) provides a means of cutting target materials (70) without liquefaction and a means of sealing the newly cut edges of the target materials (70) together, also without liquefaction of the target materials (70).

  • Patent number: 5896452
    Abstract: A two-wire line and a four-wire line telephone system interface with each other through a hybrid (12). After a connection between the two and four-wire line systems is made, an echo canceler (10) provides training signals to the hybrid on the transmit path an generates echo cancellation signals on the receive path. An adaptive filter (16) is employed to provide the proper echo cancellation signals, while a controller (22) provides filter coefficients based on an error signal. The training signals include the convolution of an impulse function with a sin(x)/x function. Once the filter coefficients are determined for the particular call, the transmit path of the four-wire line system is switched in and voice data between the two systems my commence.
