  • Patent number: 12216926
    Abstract: A method for dispatching input-output in a system. The system may include a centralized processing circuit, a plurality of persistent storage targets, a first input-output processor, and a second input-output processor. The method may include determining whether the first input-output processor is connected to a first target of the plurality of persistent storage targets; determining whether the second input-output processor is connected to the first target; and in response to determining that both the first input-output processor is connected to the first target, and the second input-output processor is connected to the first target, dispatching a first plurality of input-output requests, each to either the first input-output processor or the second input-output processor, the dispatching being in proportion to a service rate of the first input-output processor to the first target and a service rate of the second input-output processor to the first target, respectively.

  • Patent number: 12208822
    Abstract: Four-wheel steering of a vehicle, e.g., in which leading wheels and trailing wheels are steered independently of each other, can provide improved maneuverability and stability. A first vehicle model may be used to determine trajectories for execution by a vehicle equipped with four-wheel steering. A second vehicle model may be used to control the vehicle relative to the determined trajectories. For instance, the second vehicle model can determine leading wheels steering angles for steering leading wheels of the vehicle and trailing wheels steering angles for steering trailing wheels of the vehicle, independently of the leading wheels.

  • Patent number: 12195221
    Abstract: A cleaner assembly for an apparatus for making pouch products includes a cleaner roller and a poker roller. The cleaner roller may counter rotate with a rotatable drum of the apparatus, in contact with an upper surface of a first elastic layer on the rotatable drum, and at a greater tangential speed than at least one surface of an outer circumferential surface of the rotatable drum or an upper surface of the first elastic layer. The poker roller includes projections that are each configured to extend into one or more divots of the rotatable drum. The poker roller may counter rotate with the rotatable drum and at a same tangential speed as the at least one surface such that the projections extend into and out of separate, respective divots of the rotatable drum based on the counter rotation of the poker roller and the rotatable drum.

  • Patent number: 12162500
    Abstract: Techniques for accurately predicting vehicle state errors for avoiding collisions with objects detected in an environment of a vehicle are discussed herein. A vehicle safety system can implement a model determine a representation of the vehicle usable in a scenario. The model may dynamically determine a size and/or a heading of the vehicle representation based on differences between a candidate trajectory and a current trajectory of the vehicle. The safety system can identify a potential collision between the vehicle and the object based at least in part on an overlap of the vehicle representation and an object representation.

  • Patent number: 12145618
    Abstract: Four-wheel steering of a vehicle, e.g., in which leading wheels and trailing wheels are steered independently of each other, can provide improved maneuverability and stability. Steering angle constraints may be used to limit or prevent saturation of steering by only one set of wheels as well as to reduce sideslip. The steering angle constraints are vehicle independent and applicable across a fleet of different vehicles based on vehicle speed. For instance, the steering angle constraints establish angle limits that dynamically adjust based on vehicle speed to ensure vehicle velocity and acceleration remain within predefined limits as established by autonomous vehicle system design.

  • Patent number: 12137976
    Abstract: An ophthalmic optical coherence tomography instrument, method, and computer-readable medium. The instrument includes a scanner defining an apparent point source for scanning sample light across a subject position and an objective having a posterior imaging configuration to project the apparent point source onto a pivot point between the objective and the subject position. The objective is settable between the posterior imaging configuration for scanning the sample light across a retina of an eye at the subject position and an anterior imaging configuration for scanning the sample light across a pivot plane. An axial region from which an interferogram is detectable extends across the pivot plane while the objective is in the anterior imaging configuration. A pupil alignment method uses the anterior imaging modality to obtain a structure position of a structure of an eye's anterior segment and then an offset between the structure position and a reference position.

  • Publication number: 20240358949
    Abstract: An improved system and method of determining a low water and/or water-out condition in a humidifier chamber of a respiratory or surgical humidifier system can use a specific frequency band to detect changes in a temperature of a heater plate. The temperature changes can correlate to the specific heat capacity value of the humidifier chamber. The low water and/or water-out detection process can be performed without having to determine the gases flow rate and/or can be run continuously. A heater plate assembly of the system can include a compliant insulation sheet to improve thermal coupling between the heating element and the top heating plate of the heater plate assembly, thereby improving the low water and/or water-out detection process.

  • Publication number: 20240309923
    Abstract: Some embodiments relate to an electro-mechanical coupled to a first mounting point and a second mounting point. The electro-mechanical actuator includes a screw, a first nut on the screw, a sensor assembly, a first motor, and a backup motor. The first nut is coupled to the first mounting point. The sensor assembly generates signals indicative of (a) the position of the first nut on the screw or (b) changes in the position of the first nut on the screw. The first motor can rotate the first nut about a screw axis of the screw. The backup motor can rotate the first nut about the screw axis of the screw. A controller module can control the first motor or the backup motor based on the signals generated by the sensor assembly.
