Abstract: Presently disclosed embodiments are directed to a process and mechanism for reducing human error and manual labor used to sweep pockets on a mail sorting machine. Specifically, the disclosed embodiments utilize a sliding drawer holding a receiving container that can mate in a flush arrangement with an output pocket of a mail sorting machine. Thus, sweeping of mail product from the output pocket to the receiving container can be accomplished in one motion that empties the entire output pocket into the receiving container. This sweeping may be performed by an operator without any errors caused by sweeping to an incorrect receiving container or issues caused by dropping sorted mail product and picking it back up in a different order.

Abstract: In accordance with presently disclosed embodiments, a 5-switch power conversion circuit that improves the power conversion efficiency (PCE) of a DC-DC converter with a double chopper topology is provided. The power conversion circuit adds minimal complexity through an additional switch, while preserving the benefits of a 3-level boost converter topology. The disclosed power conversion circuit uses four switches that are arranged in a 3-level boost converter arrangement, and a fifth switch that is connected in parallel with two of the other switches. The fifth switch helps to reduce the conduction power losses through the DC-DC converter by providing a one-switch ON-state conduction path instead of a two-switch path during part of the DC-DC power conversion cycle.

Abstract: The preferred embodiments of the present invention provide two advantageous features, which are especially beneficial in combination, but which can be advantageously and beneficially employed independently of one another: (1) firstly, a self-cooling motor bearing system; and (2) secondly, a self-lubricating motor bearing system. In the preferred embodiments, one or both of these two advantageous features are integrated inside an electric motor (e.g., within the electric motor's enclosure housing) in such a manner as to greatly enhance bearing operating conditions (e.g., maintaining adequate bearing lubrication and/or bearing operating temperature) without the use of external lubrication units and/or external cooling units.

Abstract: An inductor-capacitor (LC) filter designed to comply with EMC (Electromagnetic Compatibility) standards comprises capacitors; switches for coupling capacitors; differential-mode inductors for coupling capacitors and switches; and common-mode inductors or a combination of differential-mode inductors and common-mode inductors, where an input signal changes the inductance of differential-mode inductors in the LC filter to modify a frequency response of the LC filter. In the LC filter, differential-mode inductors further comprise identical multiple-winding inductors, and the input signal, which biases the plurality of differential-mode inductors, includes a DC signal or a combination of DC and AC signals. A corner-frequency of the LC filter is adjusted and approximated as: fc=1/(2×pi×sqrt(L×C)), where fc is the corner-frequency, L is a composite value of inductance, and C is a composite value of capacitance.

Abstract: A bank note processing system having a combined florescence and phosphorescence detection system. The bank note processing system includes a detection module which has a detector housing having a first compartment and a second compartment separated by a light baffle. An illumination source and a first sensor module are disposed in the first compartment of the detector housing and a second sensor module is disposed in the second compartment of the detector housing. The illumination source directs light to the bank note and the first sensor module measures the bank note's florescence at a first point in time. The second sensor module measures the bank note's phosphorescence at a second point in time and the detection module determines whether the bank note is a counterfeit bank note using the measured florescence and the measured phosphorescence.

Abstract: Presently disclosed embodiments are directed to systems and methods for bundling smaller stacks of bank notes into larger sized bundles that are efficient for transportation. The system may include an in-line bundler disposed along pockets of a currency processor for receiving stacks of bank notes directly from the pocket. That way, the smaller stacks of bank notes do not have to be removed from the currency processor and transported to a separate bundler machine. Instead, the currency processor features a desired number of bundler machines disposed in-line with the corresponding pockets where the bank notes are initially received and stacked. This arrangement may enable efficient stacking and bundling of bank notes sorted via the currency processor.
