  • Patent number: 11952967
    Abstract: Various embodiments of a vortex hybrid motor are described herein. In some embodiments, the vortex hybrid motor may include a housing with a solid propellant positioned within the housing, and an injector ring positioned at a proximal end of the housing. The injector ring can include a plurality of angled injector units each including a first injector and a second injector angled towards an impingement point. A first fluid stream of a liquid propellant dispensed from the first injector can collide with a second fluid stream of the liquid propellant dispensed from the second injector to atomize the liquid propellant and form a spray fan formation. At least one of the first injector and the second injector can be positioned at an injection angle relative to the sidewall to create a swirl flow of the atomized injector fluid.

  • Publication number: 20240073003
    Abstract: A method of data transfer from a tenant to a service provider comprises encrypting the data with a public key of a key pair generated by a secure device within the service provider system. The data thus cannot be accessed by the service provider during transmission. The data is generated with a corresponding access control list, which specifies that a valid certificate must be presented in order to grant a particular use of the data once stored. The tenant can thus retain control of the use of the data even though it has been transferred out of the tenant system. A method of controlling use of data securely stored in the service provider system comprises issuing a use certificate having an expiry time to the party requesting use of the data. The use certificate must be validated before use of the stored data is granted. This enables the tenant to grant use of the stored data for a limited time period.

  • Publication number: 20210022659
    Abstract: A wearable device comprising a data logger, a motion sensor, and a memory component is disclosed for recording motion data. The motion sensor may detect movement of the device when worn by a subject, and the memory component may store motion data from the motion sensor. A casing may be included for retaining the data logger and providing a contact barrier between at least part of the data logger and the subject. The contact barrier may substantially prevent contact contamination of at least part of the data logger while the device is worn by the subject for collection and storage of subject-specific motion data.
