Abstract: An authentication server verifies the initiating device of a request for authentication is a trusted endpoint prior to proceeding with the authentication process to prevent an Adversary in the Middle (AiTM) attack on a deployed Multi-Factor Authentication (MFA) system. The server may verify that the initiating device is a trusted endpoint based on matching Internet Protocol (IP) addresses for the initiating device and a confirming device associated with an authorized user or by verifying the identity of the user based on video of the user captured by the initiating device. Verification that the initiating device is a trusted endpoint may be performed prior to sending a request for confirmation of the requestion for authentication to the confirming device or may be used to establish trust before issuing or updating a certificate to the initiating device for a certificate based authentication procedure.

Abstract: A water heater including a cabinet having an inlet, an outlet, and a flow path disposed between the inlet and the outlet and having a plurality of upper and lower junctions to redirect the flow path. Each lower junction includes a drain port. A flow rate sensor measures the flow rate of the fluid through the flow path, an inlet temperature sensor measures an inlet temperature, an and outlet temperature sensor measures the outlet temperature. Heating elements are disposed along the flow path between the inlet and outlet temperature sensors, and intermediate temperature sensors are disposed adjacent respective heating elements to measure an intermediate temperature within the flow path. A controller operates the heating elements to heat a fluid within the flow path to a predetermined set point temperature based on the measurements of the flow rate sensor and temperature sensors.

Abstract: As a farming machine travels through a field of plants, the farming machine operates in a normal operational state to perform one or more farming operations. The farming machine detects an operational failure of a component of the farming machine using measurements obtained from one or more sensors coupled to and monitoring the farming machine. The operational failure of the component impacts performance of a first farming operation of the farming operations. The farming machine configures the farming machine to operate in a remedial operational state. In the remedial operational state, the farming machine diagnoses the operational failure of the component using the obtained measurements. In the remedial operational state, the farming machine selects a solution operation to address the operational failure of the component based on the diagnosis. The farming machine performs the determined solution operation.

Abstract: Electrostimulation systems and methods are contemplated in which a high current level, charge balanced alternating current electrical signal is generated for delivery to the cortex region of a patient's brain for treating opioid use disorder and substance use disorder. By stimulating this region of the brain with a charged balanced stimulation current with a stimulation current envelope defining one or more series of pulses at particular frequencies and durations designed to evoke metabolic response in the neurons, significant improvements in efficacy and reductions in patient discomfort may be achieved relative to earlier methods of transcranial electrical stimulation. Further advantages, especially in promoting neural entrainment, may be realized as well via utilizing multiple series of pulses at different frequencies, and via the dynamic adjustment of the stimulation waveform via incorporation of feedback signals in order to maintain charge balance in real-time.

Abstract: Electrostimulation systems and methods are contemplated in which a high current level, charge balanced alternating current electrical signal is generated for delivery to a patient's brain for the treatment of mild traumatic brain injury (mTBI) and post-concussion symptoms. By stimulating the brain with a charged balanced stimulation current with a stimulation current envelope defining one or more series of pulses at particular frequencies and durations designed to evoke metabolic response in the neurons, significant improvements in efficacy and reductions in symptoms and pain may be achieved relative to earlier treatment techniques. Further advantages, especially in promoting neural entrainment, may be realized as well via utilizing multiple series of pulses at different frequencies, and via the dynamic adjustment of the stimulation waveform via incorporation of feedback signals in order to maintain charge balance in real-time.

Abstract: Systems and methods are provided for processing a set of multiple serially acquired magnetic resonance spectroscopy (MRS) free induction decay (FID) frames from a multi-frame MRS acquisition series from a region of interest (ROI) in a subject, and for providing a post-processed MRS spectrum. Processing parameters are dynamically varied while measuring results to determine the optimal post-processed results. Spectral regions opposite water from chemical regions of interest are evaluated and used in at least one processing operation. Frequency shift error is estimated via spectral correlation between free induction decay (FID) frames and a reference spectrum. Multiple groups of FID frames within the acquired set are identified to different phases corresponding with a phase step cycle of the acquisition. Baseline correction is also performed via rank order filter (ROF) estimate and a polynomial fit.

Abstract: Methods and systems disclosed herein enable tracking user actions by generating different visually scannable codes (e.g., QR codes) for combinations of user, operator, and action(s). Each visually scannable code may be stored with user action data and an operator identifier and linked to another visually scannable code corresponding to the user. When a visually scannable code is scanned, all data associated with the visually scannable code and data associated with other linked visually scannable codes is generated for display. By generating the visually scannable codes and storing the codes in a linked state, the system is able to provide quick and efficient data retrieval.

Abstract: An atomic object confined in a particular region of a confinement apparatus is cooled via a simultaneous sideband and Doppler laser cooling operation. A controller controls first and second manipulation sources to provide first and second two-photon transition manipulation signals to the particular region. The controller controls a third manipulation source to provide a repump manipulation signal to the particular region.

The repump manipulation signal is configured to repump the atomic object from the second ground state to the first ground state via an excited state. The repump manipulation signal is red detuned from a transition from the second ground state to the excited state by a repump detuning configured to cause Doppler cooling of the atomic object.
