Abstract: A vibratory screening machine includes replaceable screen assemblies. Compression mechanisms are used to secure replaceable screen assemblies to the vibratory screening machine. Each compression mechanism applies a force to a replaceable screen assembly that includes both a horizontal component and a downward vertical component. Each replaceable screen assembly is typically substantially flat prior to installation on a vibratory screening machine. The force applied to a screen assembly by one or more compression mechanisms causes the screen assembly to be pushed into engagement with underlying concave support members such that the screen assembly itself assumes a concave shape with the center of the screen assembly being lower than the side edges. The vertical downward component of the force helps to secure the screen assembly to the screening machine.

Abstract: A roller-and-rail cargo handling system that includes tracked rollers and side rails for receiving cargo pallets. A trolley system is used to move the pallets along the tracked rollers, which includes a trolley movable along a trolley track by one or more cables. The trolley includes (1) a body sized and configured for sliding beneath the pallet located on the tracked rollers, and (2) a pawl in a cavity of the body which is mounted for rotation between closed and open positions. In the open position the pawl extends above an upper surface of the body to engage a cutout of a pallet and exert a moving force thereto, and in the closed position the pawl is sufficiently within the cavity to permit the trolley to slide beneath the pallet without engagement thereof.

Abstract: Joint noise and echo suppression may be performed for enhancing two-way audio communications. Audio data is captured at a communication device and audio data transmitted to the communication device from another communication device are used as input features to a trained machine learning model that uses the transmitted audio data as a reference signal to eliminate residual echo in the captured audio data when also suppressing noise in the captured audio data.

Abstract: Described are exemplary embodiments of a syringe identification system for use with a positive displacement pipette, such as a handheld powered positive displacement pipette. An exemplary syringe identification system may include a sensor, such as a color sensor, that is located at or near a distal end of the pipette and arranged such that the sensor is operative to read an identifying marking(s) on a syringe that has been installed to the pipette. The sensor may be a color sensor having an illumination source and configured to read a color code on the syringe. The color code may be usable to identify the syringe to the pipette.

Abstract: One embodiment described herein provides a system and method for simulating behavior of a quantum circuit that includes a plurality of quantum gates. During operation, the system receives information that represents the quantum circuit and constructs an undirected graph corresponding to the quantum circuit. A respective vertex within the undirected graph corresponds to a distinct variable in a Feynman path integral used for computing amplitude of the quantum circuit, and a respective edge corresponds to one or more quantum gates. The system identifies a vertex within the undirected graph that is coupled to at least two two-qubit quantum gates; simplifies the undirected graph by removing the identified vertex, thereby effectively removing the two-qubit quantum gates coupled to the identified vertex; and evaluates the simplified undirected graph, thereby facilitating simulation of the behavior of the quantum circuit.
