  • Patent number: 11976610
    Abstract: A constant density heat exchanger and method of operating are provided. The constant density heat exchanger includes a housing extending between a first end and a second end and defining a chamber having an inlet and an outlet. A first plate is positioned at the first end of the housing and rotatable about an axis of rotation such that the first plate selectively allows a working fluid to flow into the inlet of the chamber. A second plate is positioned at the second end of the housing and rotatable about the axis of rotation such that the second plate selectively allows the working fluid to flow out of the outlet of the chamber. The first plate and the second plate are rotatable about the axis of rotation so as to hold a volume of the working fluid at constant density as a heat source imparts thermal energy thereto.

  • Publication number: 20240108847
    Abstract: A breathing assistance apparatus and method of controlling a breathing assistance apparatus is disclosed. Particularly, the breathing assistance apparatus is controlled such that it has a drying cycle to enable drying of the tubing that supplies gases to a user and prevent the harbouring of pathogens within the tube. The drying cycle is preferably operated automatically by internal controllers in the apparatus. However, it may be manually activated by pressing a button on the apparatus. The drying cycle is preferably activated at the end of a user's treatment session.

  • Publication number: 20240022590
    Abstract: In an embodiment, a vulnerability scanner component determines one or more target software objects of a remote file system for a vulnerability scan, and performs, via a file system application programming interface (API), a file system decoding procedure based on information associated with the remote file system to determine a subset of disk blocks of the remote file system that comprise the one or more target software objects. The vulnerability scanner component transmits, to a remote device, a read request associated with the subset of disk blocks, and obtains, in response to the read request, the subset of disk blocks (e.g., rather than a full disk image). The vulnerability scanner component extracts the one or more target software objects from the subset of disk blocks, and performs the vulnerability scan on the extracted one or more target software objects.

  • Publication number: 20230256831
    Abstract: A technique provides power-limiting regenerative braking to a utility vehicle. The technique involves detecting that the utility vehicle is moving in a forward direction at a first speed. The technique further involves applying a first regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the first speed. The technique further involves detecting that the utility vehicle is moving in the forward direction at a second speed which is less than the first speed. The technique further involves applying a second regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the second speed. The second regenerative braking power level is lower than the first regenerative braking power level.

  • Patent number: 11673474
    Abstract: A technique controls regenerative braking to reduce skidding of a vehicle. Such a technique involves imparting rotation to an alternating current (AC) electric motor to move the vehicle to a first commanded vehicle speed; applying a regenerative braking power to the AC electric motor to bring the vehicle to a second commanded vehicle speed; while applying the regenerative braking power, adjusting the level of regenerative braking power applied to follow a predetermined speed reduction rate; while adjusting the level of regenerative braking power applied, provide a limit to the maximum level of regenerative braking power available; and while providing the limit to the maximum level of regenerative braking power available, adjusting the limit to the maximum level of regenerative braking power available based on a current speed of the vehicle.
