Abstract: An apparatus and method for sensing load current of an envelope tracking (ET) modulator enables load impedance of a power amplifier to be measured. Impairments associated with the load impedance characteristic can be suppressed by calibration and predistortion instead of by feedback (as done in the prior art). The ET modulator provides a switching regulator that can be reconfigured as a linear regulator for the purpose of sensing the load current. This allows the ET modulator to be operated open-loop, thereby eliminating the power consumption overhead resulting from utilization of a loop filter and error amplifier (used in the prior art) and achieving a higher overall efficiency.

Abstract: Method and apparatus for half folding sequentially and nesting a plurality of paper sheets. The apparatus includes a buckle chute folder, the folder having a first pair of feed rollers rotatable at a given velocity, and a device for continuously feeding the paper sheets in shingled relationship at a second velocity greater than the given velocity to the feed rollers. The shingled relationship is defined by an overlap of the sheets of at least one-half of the length of the sheets. By using the apparatus and method, any desired number of sheets may be folded sequentially and nested one inside the other.

Abstract: A reversible collating machine for stacking sheets of paper being fed seriatim thereto from a singulating feeder in the same or reverse order as the sheets appear in the singulating feeder. The reversible collating machine includes a housing, apparatus secured to the housing for rotatably mounting endless, elastic belts, at least one upper, endless, elastic belt rotatably mounted to the mounting apparatus, and at least one lower, endless, elastic belt rotatably mounted to the mounting apparatus. Each of the belts includes an upper and a lower reach, the lower reach of the upper belt being situated slightly above the upper reach of the lower belt to thereby frictionally engage and transport the sheets of paper.

Abstract: A collating station is disclosed for a machine intended to insert first and second documents into an envelope. Prior to the insertion operation, the first and second documents are advanced serially in a common plane. At a predetermined location, each first document is intercepted and lifted above the common plane and moved to a holding platform spaced above the common plane. The holding platform has a transverse terminal edge downstream from where the first document comes to rest. Thereupon, the first document resting on the holding platform and a following second document which continues to advance along the common plane as the first document travels toward the holding platform are advanced together in a parallel spaced relationship, toward a downstream station. As the documents are advanced, the first document drops off the terminal edge of the holding platform and onto the second document thereby completing the collating operation.

Abstract: A document collating and inserting system having displays for document count verification. A plurality of bank checks belonging to a check set are fed, counted and stacked at a stacking station while simultaneously an associated statement is fed to an imaging station where a number imprinted thereon is imaged by a video camera and displayed on a video monitor. The number represents a predetermined number which should equal the actual number of checks counted, the actual count also being displayed. An operator makes a visual comparison of the two displayed numbers and, if they are in agreement, initiates a cycle of the system thereby forming a collation of the statement and checks and transporting them to a holding station. From the holding station the collation is inserted within an envelope provided by an envelope feeder during the next cycle of the system. If the two numbers are not in agreement a mismatch switch is provided for the operator to activate before cycling the system.

Abstract: An improved separator assembly for document feeders comprises a retarding roller and a cooperating opposed feed roller.

The retarding roller includes at least one cylindrical portion and another portion which has an interfering member projecting outwardly from the roller. Other surfaces of the retarding roller may comprise different materials in order to avoid scratches on the documents to be fed or to change the frictional force on the documents.

Abstract: A bursting machine is provided for separating discrete sheets from a continuous strip of sheets having uniformly spaced perforation lines across the width of the strip. A gauging device with numerical increments in the form of a linear scale is manually compared to the length of the discrete sheets to provide a predetermined number corresponding to a pulse count for entering into a control device through a manually settable device. The control device in turn is operatively connected to an electronic pulse counter. When the leading edge of the strip advances a predetermined increment after passing through a sensing device located downstream in the path of travel with respect to a first pair of feed rollers, a pulse generator attached to the driven first feed roller is actuated to generate pulses for counting to reach the preset number in the pulse counter.
