Abstract: Additive manufacturing or 3D printing produces considerable quantities of waste ink or resin during the course of additive manufacture. The waste ink is a hazardous substance and must be collected and disposed of accordingly. The present embodiments provide a waste ink collection device that collects the waste ink from the printing process, or from head cleaning and other incidental operations, stores the waste and cures it. The waste ink is thus rendered safe for conventional disposal. A waste ink disposal cartridge collects the waste ink and carries out curing.

Abstract: An engine speed of work vehicle can be controlled automatically based on various conditions. For example, an excavator can include a first sensor for detecting a vehicle characteristic and transmitting an associated first sensor signal, and a second sensor for detecting an engine characteristic and transmitting an associated second sensor signal. The excavator can include a control circuit for receiving the sensor signals. The control circuit can determine the vehicle characteristic based on the first sensor signal and the engine characteristic based on the second sensor signal. The control circuit can determine that at least one vehicle condition of multiple vehicle conditions is satisfied based on the vehicle characteristic, and that at least one engine condition of multiple engine conditions is satisfied based on the engine characteristic. The control circuit can transmit a signal configured to cause the excavator to reduce an engine speed to a low idle engine speed.

Abstract: There is provided herein an encoded information reading terminal such as may be provided for by a bar code reading terminal for operation in a network such as a retail store network that is configured in one embodiment to automatically enter a unique association mode of operation subsequent to wirelessly receiving a radio address from one computer of a plurality of computers, e.g., a cash register address from one cash register out of a plurality of cash registers. In one embodiment a bar code reading terminal can be configured to wait for a cash register address to be wirelessly received as part of a connection request initiated from one cash register out of a plurality of cash registers. A bar code reading terminal can be configured so that when operating in a unique association mode, a bar code reading terminal transmits all decoded bar code messages output by the bar code reading terminal to an external device to the one cash register sending its cash register address.

Abstract: A retail store network comprising a cash register, server, and hand held optical reader for reading a bar code symbol of an item and generating a decoded out bar code data message. The hand held bar code reader has an electrical connector and a wireless transceiver. The optical reader can be used with a base unit also having an electrical connector and a wireless transceiver. The network is configured so that the hand held bar code reader and the base unit have one linking mode in which the address of the base unit is sent to the hand held bar code reader through their respective electrical connectors. The linking process is completed by way of wireless communication, including the transmission of the address of the hand held bar code reader to the base unit.

Abstract: An attenuator for optical signals includes a base. A first ferrule has a first optic fiber passing through a central bore therein and attached to a first lens at an end of the first ferrule. The first ferrule is fixed in position relative to the base. A second ferrule has a second optic fiber passing through a central bore therein and attached to a second lens at an end of the second ferrule. The second lens faces the first lens. The second ferrule is fixed to the base and can be moved relative to the base by a user adjustment feature, so that the second lens may be moved relative to the first lens. The relative placement between the first and second lens controls the attenuation of the attenuator.

Abstract: The invention is a system and method for providing optimized accuracy and precision in analog-to-digital conversions of data. In an embodiment of the invention, an AID converter is configured by setting two separately definable reference voltages that are controlled by a microprocessor. The A/D converter range is as wide as, or slightly greater than, a dynamic range of the analog signal to be converted. The microprocessor adjusts at least one reference voltage. The A/D converter receives analog signals from a sensor. The dynamic range of the signal from the sensor, or the sensor operating conditions, are used to define the reference voltages. The converted data is provided to a data processor at a rate controlled by a clocking signal. In a method according to the invention, the A/D converter is operated using the features described above. The accuracy and the precision of the converted data are thereby optimized.
