    摘要： An exemplary air cushion inflation machine includes: a first terminal connected to a direct current input; a second terminal; a reference resistor powered by the direct current input; an op-amp; and a transistor. The first terminal of the op-amp is connected to a variable voltage source and the second terminal of the op-amp is connected to the reference resistor. The transistor has a base connected to an output of the op-amp, an emitter connected to the reference resistor, and a collector connected to a first terminal of a sealing band apparatus having first and second terminals. A meltable material placed between the first and second terminals is melted by resistance of current flowing between the first and second terminals. The variable voltage source changes voltage based on a voltage drop measured across the first and second terminals by a voltage measurement device and the constant current.

    摘要： A bagger safety system includes a controller, a heating element, a light-emitting device, a light-detecting device and a backing assembly. The backing assembly includes a backing bar, a pair of reflectors and a seal backing element movably coupled to the backing bar by at least one mechanical force generating member so as to create a space between the seal backing element and the backing bar when no external force is applied to the mechanical force generating member. Light emitted from a light-emitting device reflects off the reflectors to the light-detecting device when no external force is applied to the mechanical force generating member. Movement of the seal backing element toward the backing bar prevents light emitted from the light-emitting device from reaching the light-detecting device and the controller controls movement of the backing assembly toward the heating element based on whether light from light-emitting device reaches the light-detecting device.
