Method and apparatus for discriminating and counting documents
InactiveUS6915893B2Simple and compactEasy to usePaper-money testing devicesCoin/currency accepting devicesEngineeringMechanical engineering
A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack. The device includes an input receptacle for receiving a stack of bills to be evaluated and a single output receptacle for receiving the bills after they have been evaluated. A transport mechanism transports the bills, one at a time, from the input receptacle to the output receptacle along a transport path. The device further includes a discriminating unit that evaluates the bills. The discriminating unit comprises two detectors positioned along the transport path between the input receptacle and the output receptacle. The detectors are disposed on opposite sides of the transport path so that they are disposed adjacent to opposite sides of the bills. The discriminating unit counts and determines the denomination of the bills. The evaluation device also includes means for flagging a bill when the denomination of the bill is not determined by the discriminating unit.

Microscale capacitive deionization apparatus
ActiveUS20080023333A1Little chanceFlexibility in production sizeElectrolysis componentsElectrostatic separatorsCapacitanceCapacitive deionization
The present device is a microchannel separator that uses a separation driving force created by an electric field. An ionic fluid flows through the microchannels and is subjected to an electric field by two spaced apart parallel electrodes possessing an electric charge. The ions in the ionic fluid are attracted towards the charged electrodes and thus are concentrated in the region of flow near the charged electrodes and depleted from the central region of flow between the charged electrodes. The charged electrodes are insulated from the ionic fluid by an impermeable barrier which prevents arcing and adherence of the ions to the charged electrodes. After a sufficient length of passage of the ionic fluid through a main channel two blocking plates separate the flow into a central and two outer output channels. The central channel draws a portion of the ionic fluid from the central region of the main channel that has fewer ions than the ionic fluid in the regions near the charged electrodes. The concentrated ionic fluid in the outer channels is discharged separately from the central channel.

InactiveUS20060251204A1Small sizeGenerating large amountElectrical apparatusReaction to electrical energyElectric forceElectricity
The invention describes a product and a method for generating electrical power directly from nuclear power. More particularly, the invention describes the use of a liquid semiconductor as a means for efficiently converting nuclear energy, either nuclear fission and / or radiation energy, directly into electrical energy. Direct conversion of nuclear energy to electrical energy is achieved by placing nuclear material in close proximity to a liquid semiconductor. Nuclear energy emitted from the nuclear material, in the form of fission fragments or radiation, enters the liquid semiconductor and creates electron-hole pairs. By using an appropriate electrical circuit an electrical load is applied and electrical energy generated as a result of the creation of the electron-hole pairs.

A simulation device for simulating and exploring the effects of different policies used on a machine in a manufacturing system. The simulation device representing the machine includes controls to allow the participation of an operator in simulation modeling. The operator initiates the simulation process by, for example, loading a block into the simulator according to a hypothesis policy. During the simulation, a computer records all the changes in the system and those changes are transmitted to the computer. When the simulation stops, the total number of items completed by the system represents the throughput of the system during the simulation time. The operator can view the results of the simulation and change the policies and repeat the simulation using the same system structure or parameters.

Electromagnetic active vibration control system and electromagnetic actuator
InactiveUS6974006B2Accurate and robust and efficientEasy constructionPortable framesMechanical oscillations controlControl systemFeedback control
A multi-sensor, multi-actuator control system for controlling vibration in a mechanical structure. The system employs feedforward and feedback control strategies in tandem. Outputs from adaptive feedforward and modal feedback control loops are added to each other. The control system may be dynamically adapted to the changing physical characteristics of the controlled structure. For example, the plant transfer function estimates for the feedforward unit and the gain for the feedback unit may be calculated as functions of sensed physical parameters (location, mass, etc.), and the plant transfer function estimates may be dynamically modified to reflect time-varying feedback control gains. If desired, the control system may be used to cancel low frequency vibrations (<20 Hz) in industrial processes. The actuators may be formed of electromagnets, fixed armatures and interposed flux sensors. In a preferred embodiment of the invention, the robust actuators are sealed so as to be impervious to fluids and dust.
