Abstract: A decentralized digital identity exchange (IDX) is provided. In response to receiving a request for identity verification of a user, the IDX transmits, to a digital wallet associated with the user, a request for current biometric data. The current biometric data is received from the digital wallet and a biometric liveness check is performed. In response to the biometric liveness check succeeding, the IDX generates a verification transaction ID (VTID) and a verifiable credential for the user. The VTID is a unique identifier that comprises a representation of when the identity of the user was verified by the IDX. The verifiable credential and VTID are transmitted to the digital wallet which sends them to a relying party computing system to verify the identity of the user to the relying party computing system.

Abstract: A firearm platform and method of connecting an upper receiver to a lower receiver. The upper receiver has a pivot lug and a takedown lug with perimeter openings in opposite directions. The lower receiver has a locking member that pushes against the takedown lug which causes the upper receiver to displace forward. As a result of the forward displacement, a pivot pin in the lower receiver exerts an opposing force against the pivot lug. The locking member is displaced between a locked and unlocked position through a lever located on an exterior surface of the lower receiver. When the locking member is in the locked position, the lower receiver and uppers receiver form a connection that is tight and free from slop.

A first signaling path includes a first delay circuit to dynamically delay a first set of the multiple sets of signals by a first delay that is based on a phase difference between a reference clock and an as-received version of the first set of the multiple sets of signals fed back from the on-chip clocked-device circuitry. A second signaling path is disposed in parallel with the first signaling path and includes a second delay circuit to dynamically delay a second set of the multiple sets of signals by a second delay and is based on a phase difference between the reference clock and an as-received version of the second set of the multiple sets of signals fed back from the on-chip clocked-device circuitry.

Abstract: A flowmeter system including a flowmeter having a body defining a flow channel and a recess. A paddle wheel is positioned in the recess and is rotatable in response to gas flow through the channel. An optical source provides a light beam on an input cable that crosses the recess and is received by an output cable. A light detector receives the light beam from the output cable. The light beam is intermittently interrupted by the paddle wheel as the paddle wheel rotates so that the light beam on the output cable is a pulsed light beam. Processing electronics converts the pulsed light beam to a rotational speed of the paddle wheel that is then converted to a gas flow rate through the flow channel. The flowmeter is positioned in the hazardous environment of a painting robot and the processing electronics is positioned outside of the hazardous environment.

Abstract: An integrated circuit (IC) chip includes transmit circuitry including multiple transmitters to launch parallel data in response to a transmit clock signal. The transmit clock signal is based on a reference clock signal. Receiver circuitry includes multiple receivers to receive the parallel data in response to a receive clock signal. The receive clock signal is based on the reference clock signal. Bus circuitry includes multiple data paths arranged in parallel between the transmit circuitry and the receiver circuitry.

A first data path of the multiple data paths includes a delay circuit to dynamically delay first data of the parallel data propagating along the first data path by a first delay that is based on a channel delay exhibited by a second data path of the multiple data paths.

Abstract: A device for extracting arterial and pulmonary embolisms. Blood containing unwanted material is suctioned out of a patient, is filtered in the reservoir, and is returned to the patient. The device includes a suction catheter and a return catheter attached to a filter reservoir. The device may also include a daughter catheter to reach smaller spaces and a fishing catheter to catch and reel the unwanted material toward the suction catheter. The reservoir is a two-stage filter that filters out any unwanted material from the blood and de-airs the blood prior to returning the blood back to the patient. The suction system can be manual or controlled by a console integrated with computer readable instructions and algorithms to safely return the filtered and de-aired blood.

Abstract: A spiral wound membrane module is suitable for use with high temperature water that may also have a high pH, for example steam injection produced water. The module uses a membrane with a polyphenylene sulfide (PPS) backing material. The feed spacer of the module may be made from polyphenylene sulfide (PPS) or ethylene chlorotrifluoroethylene (ECTFE). The permeate carrier may be made of a woven nylon (i.e. nylon 6, 6) fabric coated with high temperature epoxy. The core tube and anti-telescoping device may be made of polysulfone. In some examples, the module may be used at a temperature of up to 130° C. Optionally, the module may be used at a pH of 9.5 or more. In a filtration method, the module may be operated at a pressure in the range of 150 to 450 psi. The module may be operated at a generally constant pressure.
