Abstract: A lifting system for a binder jetting additive manufacturing printer including a lift enclosure having a sealable access port and an aperture between an interior of the lift enclosure and a printing chamber. At least one lift column fixed to the interior of the lift enclosure is configured to vertically traverse a build box lift plate from a retracted position to a raised position, wherein in the raised position the build box lift plate indexes against at least one indexing stop. A platen lift is affixed to the box lift plate and is configured to traverse a build platen in a z-lift axis.

Abstract: A carriage unit for binder jetting additive manufacturing of components. A carriage body is movably mounted to a carriage frame within a printer unit and configured to traverse relative to a work surface. Two compaction rollers are mounted to the carriage body. Each is configured to move between a retracted position disengaged from build material powder to a deployed condition to recoat build material powder over a work surface. A powder dispensing unit is mounted to the carriage body and configured to dispense a metered amount of the build material powder as the carriage body traverses over the work surface. A print head mounted to the carriage body is configured to deposit a predetermined pattern of binder as the carriage unit traverses relative to the work surface.

Abstract: A method and apparatus are provided relating to a secure bag assembly to secure cash in transit (“CIT”). In some implementations, the secure bag assembly is installed in a lockable, removable cassette that is fitted to a bill validator. The cassette and bill validator can be installed in an enclosure like those found in retail kiosks, self-checkout terminals, retail safes or gaming machines. In such an implementation, bank notes are deposited in the bill validator and once identified and validated, are securely stacked in the bag assembly within the cassette. The bag assembly can be used for capacities of one banknote up to the maximum capacity allowed by the cassette. The bag assembly is secured in place when installed and is sealed automatically upon removal from the cassette.

Abstract: A bill acceptor module may receive configuration data from at least one of an interface board, a programming tool, a plug-in memory, a memory on a currency cassette, and a host machine, store the configuration data in a memory, and process signals according to the configuration data to enable operation of the bill acceptor module with a host machine. The operation of the bill acceptor module may include communication with a currency cassette.

Abstract: A motorized shade control system is described in which electrostatic charges, generated by a shade fabric being reeled on to and off of a roller are conducted to and grounded by the shaft of a remote drive motor. The drive motor is ultraquiet, and includes a worm gear drive and single-stage reduction gear assembly which delivers about 0.010 to 0.005 horsepower, with motor output shaft rotational velocity limited to no more than about 30RPM. The motor is mounted within a two-part housing and is clamped between elastomeric acoustic dampers connected between pedestals extending from opposite interior wall surfaces to opposite sides of the motor. An H-bridge drive circuit powers the motor under the control of a microprocessor which can be addressed by an infrared remote transmitter or by a wall mount control. Soft start and soft stop circuits are employed to further reduce noise.
