Abstract: A firearm has an emitter that propagates a light beam to a receiver and at least two finger position beams that propagate horizontally along the firearm on either side of a switch that provides detection of a position of a finger when the finger blocks and unblocks the finger position beam. Further, when only two finger position beams are blocked, this indicates proper positioning of the finger placing the firearm into a dischargeable condition.

Abstract: Exemplary embodiments relate to the secure storage of security questions through an immutable log, such as a blockchain. The security questions may be stored in a centralized location, accessible from an application or browser tab running on the user's device. When a security question is required, such as to perform a password reset on a website, the website may interact with the application or browser tab, which retrieves the question(s) from the blockchain. The user may enter their answers to the question(s), which may be hashed by the application or tab. The hashed answers may be entered into the original requesting website, which may verify with the blockchain that the correct answers have been provided. Thus, the requesting website sees neither the questions nor the answers. Additional security features may include logging requests for questions, so that a user can determine if a security question may have been compromised.

Abstract: A charging function (CHF) receives, from a policy control function (PCF), a first request for charging policy information for a packet data unit (PDU) session of a wireless device. The charging policy information is determined for the PDU session of the wireless device. The charging policy information indicates a charging method comprising one or more of: online charging; offline charging; and converged charging. A message comprising the charging policy information is sent to the PCF. The CHF receives from a session management function (SMF), a second request to establish a charging session. The second request comprises the charging method. A confirmation for the charging method is sent to the SMF.

Abstract: A system to optimize the operation of counter pulsatile cardiac assist devices includes a collection of intracorporeal and extracorporeal physiologic sensors that generate data. A control system in electrical communication with the collection of intracorporeal and extracorporeal physiologic sensors generates control signals for the counter pulsatile cardiac assist device based on a counter pulsating aortic pumping element based on the data. A low power transmitter is in electrical communication with the collection of sensors and the control system and sends the generated data and the control signals to an external computer for aggregation and analysis. The analysis is based on a set of inputs from an implanted counter pulsatile cardiac assist devices.

Abstract: A system for recoating a powder bed includes a platform holding a powder bed, a brush and an electrode assembly including an electrode and insulating shield. After powder is distributed on the powder bed the top surface of the powder bed is smoothed by the brush. A voltage supply produces a high voltage alternating current and communicates with the powder bed and the electrode. When the electrode assembly is positioned over the powder bed, the shield is between the electrode and powder bed top surface. The voltage supply produces a high voltage alternating current that creates an alternating electric field between the electrode and the powder bed that causes the powder on the top surface to oscillate in a region between the shield and the bed and then reposition themselves on the bed such that the top layer of the powder bed is smoother than it was prior to when the powder particles began oscillating.
