  • Publication number: 20240131271
    Abstract: A drive train for a wind-up injection device is described. The drive train includes a torsional energy storage adapted to be loaded or unloaded by a rotatable element, a rotatable user handle, a rotationally driveable expelling mechanism adapted to expel the liquid drug, and a clutch element coupled with the torsional energy storage via the rotatable element and including a ratchet for maintaining the rotatable element at one of a number of discrete angular positions against the torque of the torsional energy storage. The clutch element is adapted to transmit the torque from the user handle to the torsional energy storage, or alternatively from the torsional energy storage to the expelling mechanism. The ratchet is switchable from one position to an adjacent position by a torque transmitted from the user handle to the torsional energy storage. The drive train is adapted to dampen torque peaks visco-elastically and/or visco-frictionally.

  • Patent number: 11967922
    Abstract: A universal adapter for enabling truss foundations to support conventional single-axis trackers. In some cases, the adapter has a main body with an upper portion that presents a standard I-beam interface with pre-drilled holes to interface to a specific single-axis tracker. A pair of connecting portions point down and away from the main body and enable upper leg sections to connect the adapter to a pair of driven screw anchors located below it. The connecting portions may orient the truss so that the rotational axis of the single-axis tracker is aligned with the work point of the truss foundation made from the adapter, upper legs, and driven screw anchors. This will enable to the truss to interface with many different trackers much like conventional plumb-driven H-pile foundations.

  • Patent number: 11953041
    Abstract: A machine for rotary driving screw anchors into underlying ground and related. The machine has a mast with a rotary driver and a mandrel driver oriented on a common axis. The mandrel driver passes a mandrel through the rotary driver and the screw anchor to allow the mandrel to be actuated ahead of the screw anchor while the rotary driver drives the screw anchor into the ground. Alternatively, the mandrel driver may also drive a hammering drill through the screw anchor to clear a path ahead of it through subsurface rocks.

  • Patent number: 11951941
    Abstract: According to one aspect, a method includes determining when a vehicle has arrived at a destination and performing a first authentication process when it is determined that the vehicle has arrived at the destination. The first authentication process being arranged to authenticate a first party to enable the first party to interact with the vehicle. The method also includes determining when the first party has successfully completed the first authentication process, performing a second process when it is determined that the first party has successfully completed the first authentication process, determining whether the second process is successfully completed, and enabling the first party to interact with the vehicle when it is determined that the second process is successfully completed. Performing the second process includes determining when the first party is present within the sensing zone. The first authentication process and the second process are contactless with respect to the vehicle.

  • Publication number: 20240091757
    Abstract: A method for activating a catalyst is described comprising the steps of: (i) installing a reduced and passivated catalyst containing crystallites of a catalytic metal comprising nickel, cobalt or iron in elemental form encapsulated by a layer comprising an oxide of the catalytic metal in a reactor, such as a steam methane reforming reactor, in which it is to be used, and (ii) heating the reduced and passivated catalyst in the reactor under a vacuum or an inert gas to a temperature in the range (TT?X) to (TT+Y), where TT is the Tammann temperature of the catalytic metal in elemental form in degrees Centigrade, X is 400 and Y is 200, to form a catalytically active surface on the catalyst without requiring the application of a reducing gas.

  • Publication number: 20240077781
    Abstract: Conventional high performance computer connections are electron-based systems, which require the memory packages to be as close as mechanically possible to the computation engine. Low power and high bandwidth communication, e.g. photonic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication and augment existing memory systems to allow them to be both high capacity and high bandwidth simultaneously.

  • Publication number: 20240070013
    Abstract: Systems and methods for are provided for predicting impending failure of a database and preemptively initiating mitigating failover actions, for example by shedding connections or redirecting connection requests to an alternate database that can fulfill resources being requested. In an example embodiment, to detect a slow or unstable database, connection wait times are monitored over a rolling window of time intervals, a quantity of intervals in which at least one excessive wait time event occurred are counted during the time window, and if the quantity exceeds a threshold, the database is deemed unavailable, thereby triggering connection adjustments.

  • Publication number: 20240071593
    Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

  • Patent number: 11826749
    Abstract: A pyrolysis reactor (12) and method for the pyrolysis of hydrocarbon gases (e.g., methane) utilizes a pyrolysis reactor (12) having a unique burner assembly (44) and pyrolysis feed assembly (56) that creates an inwardly spiraling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a burner conduit (46) with a constricted neck portion or nozzle (52). At least a portion of the swirling gas mixture forms a thin, annular mixed gas flow layer immediately adjacent to the burner conduit (46). A portion of the swirling gas mixture is combusted as the swirling gas mixture passes through the burner conduit (46) and a portion of combustion products circulates in the burner assembly (44). This provides conditions suitable for pyrolysis of hydrocarbons or light alkane gas, such as methane or natural gas.

  • Publication number: 20230256406
    Abstract: A reactor and method for the conversion of hydrocarbon gases utilizes a reactor (12, 312, 412, 512, 612, 712) having a unique feed assembly with an original vortex combustion chamber (40, 340, 436, 536, 636, 736), a diverging conduit (48, 348, 448, 548, 648, 748), and a cylindrical reactor chamber (40, 340, 436, 536, 636, 736). This design creates a compact combustion zone and an inwardly swirling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a diverging conduit (48, 348, 448, 548, 648, 748). The feed streams can be introduced into the reactor at any angle (perpendicular, axial, or something between, or a combination of the above forms) with swirling flow components. This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.
