Abstract: Devices, systems, and techniques can be provided for processing an oil-containing material with an alcohol-based solvent to extract oil from the material. In some examples, a system includes an extractor configured to process an oil-containing feedstock. The extractor receives the oil-containing feedstock and conveys the material from an inlet to an outlet through the extractor. The extractor also receives an alcohol-based solvent at a solvent inlet and conveys the solvent through the extractor to a solvent outlet. The alcohol-based solvent may be ethanol. A concentration of oil in the feedstock may decrease as the feedstock moves through the extractor from the inlet to the outlet while the concentration of the oil in the solvent increases.

Abstract: An anti-theft device for securing an article of merchandise against unauthorized removal from a display counter. The anti-theft device comprises a latch plate and a pedestal having a quick-release interface. The latch plate is configured to selectively couple to the quick-release interface. A latch bolt is disposed within the pedestal. The latch bolt locks the latch plate relative to the quick-release interface. A plurality of retaining arms is configured to receive and retain an article of merchandise. The retaining arms cannot be disengaged from the article of merchandise while the latch plate is locked relative to the quick-release interface. A solenoid is housed within the pedestal and operationally connected to the latch bolt. The solenoid is configured to retract the latch bolt into a position in which the latch bolt disengages the latch plate, thereby releasing the latch plate from the quick-release interface.

Abstract: A continuously tunable radio frequency (RF) sensor system is provided. The system includes a pump laser system that includes first and second pump lasers, at least one frequency modulator to modulate frequencies of first and second laser light from the pump lasers to first and second select frequencies, a switch system to selectively pass one of the first and second laser light, an amplifier to amplify the passed laser light, a frequency doubler to double the frequency of the amplified laser light to generate pump light. A laser source lock system is in communication with the pump laser system to ensure a frequency of the pump light is referenced to atoms in a vapor cell and provide a probe light. The pump light and probe light are transmitted through the vapor cell. A detector measures the probe light that passed through the vapor cell.

Abstract: A method of printing a multi-material part in a layer-wise manner with an extrusion-based 3D printer includes providing a sliced digital model of a multi-material part and determining a number of materials in each of the slices of the digital mode. The method includes utilizing a digital model of a purge tower having N subdivisions having a closed geometry, wherein N is the number of print heads needed to print the part that is greater than or equal to three, each adjacent subdivision contact one another along an interface and assigning each print head to one subdivision and to tool paths forming the one subdivision in each layer. The method includes reassigning the assigned subdivision within the purge tower of an inactive print head in a layer to a print head that is active in the layer of the multi-material part.

Abstract: Techniques for reducing the bias error present in optical gyroscopes is disclosed. Such techniques include at least one path length adjustment member placed in an optical gyroscope resonator, which are configured to modulate the optical path length of the resonator so that bias errors attributable to the optical path length are shifted outside of the bandwidth of the optical gyroscope. In some embodiments, the at least one path length adjustment member includes a plurality of microheaters coupled to the resonator, in which case optical path length modulation is achieved by heating the resonator via the microheaters. Alternatively, a plurality of piezo-electric regions can be placed in the resonator, which enables optical path length modulation through electric field gradients applied to the piezo-electric regions.

Abstract: The invention provides a device and method for displaying chords in a musical scale based upon one or more selected root notes. The device includes planar members representing a fretboard of a stringed instrument and fingering positions for playing chords in a selected root note in a selected musical scale. The planar members are adapted to be connected to one another and permit multiple chords in multiple root notes to be displayed simultaneously in an easy to understand format.

Abstract: A holding apparatus for use in selectively securing an article includes a shaft having opposed first and second ends and a generally linear configuration. A first mounting member is attached to the first end of the shaft, the first mounting member including a magnet configured to attach to one of another magnet or metal surface. A second mounting member is attached to the second end of the shaft. In some embodiments, the second mounting member includes a magnet such that the apparatus may be selectively attached to a metal object. In another embodiment, the second mounting member may include a bore through the shaft configured to selectively receive a key ring.

Abstract: An unloading auger for an agricultural harvester includes an inner auger having an outer end and a first coupler at the outer end. The first coupler includes a first engagement cog. An outer auger is pivotally attached to the outer end of the inner auger. The outer auger has an inner end and a second coupler at the inner end. The second coupler includes a second engagement cog. The first coupler or second coupler includes at least one engagement assistor configured to rotate the outer auger prior to engagement between the first engagement cog and the second engagement cog.

Abstract: According to one embodiment, a system for enforcing physical access control and logical access control may include a physical access control system, a logical access control system, a location detection system, and a convergence system. The convergence system may be communicatively coupled to the physical access control system, the logical access control system, and the location detection system and configured to: (i) receive information from the physical access control system regarding a physical access credential; (ii) receive information from the logical access control system regarding a logical access credential; (iii) receive information from the location detection system regarding a location of a location detection tag; and (iv) based on analysis of information regarding the physical access credential, information regarding the logical access credential, and the information regarding the location of the location detection tag, determine the approximate location of a person.

Abstract: A method for enforcing physical access control and logical access control may include: (i) controlling access of a person to a physical location based on a physical access credential associated with the person provided to a physical access control system; (ii) controlling access of the person to an information system and an enterprise service based on a logical access credential associated with the person provided to a logical access control system; (iii) receiving information from the physical access control system regarding the physical access credential; (iv) receiving information from the logical access control system regarding the logical access credential; (v) determining an approximate location of the person based on the physical access credential and the logical access credential; and (vi) blocking unauthorized access between the physical access control system and the logical access control system by a first firewall.

Abstract: An interface system prevents operational interference between a vehicle power door and a ramp of an access system by interrupting power to the motors and actuators responsible for operating the door. The interface system includes a relay system that does not interrupt, read, signal, or otherwise interfere with the communication lines between a body control unit, door control unit, or remote control transmitter or receiver. Thus, the interface system functions without the need to receive and transmit signals on the vehicle's communication bus. The interface system enables the ramp controller of the access system to be a separate module, which controls the ramp and kneel functions, because the only input the ramp controller provides to the power door system is to a ground signal that mimics that of a switch included in the vehicle.
