Publication number: 20250144351Abstract: A headgear assembly for a full-face under-nose respiratory mask can include a flexible headgear connector element. A free end of each of upper straps of the headgear is coupled to the headgear connector element, which is configured to extend laterally across and be removably fastened to a frame of the respiratory mask below a tip of a user's nose. A respiratory mask assembly can include a bias vent in communication with a cushion module and configured to allow air to be exhausted from the cushion module through the bias vent. The bias vent can be provided with a diffuser including a diffuser material configured to extend over the bias vent. The diffuser material provides a tortuous air path from the bias vent through the diffuser. The bias vent and/or the diffuser can be provided on various components of the assembly.Type: ApplicationFiled: January 9, 2025Publication date: May 8, 2025Inventors: Abby Rebecca FARROW, Peter David Alexander BEARNE, Dana WILLFROTH, Jae Yun LIM, Matthew James PEDERSEN, Roheet PATEL, Birgit WUESTENHAGEN, Paul Mathew FREESTONE

Patent number: 12251518Abstract: An interface assembly includes an interface, such as a mask, that is secured to a head using a headgear assembly. The headgear assembly can include at least one halo portion and a plurality of straps. The headgear assembly can include both a front halo portion and a rear halo portion. In some arrangements, the headgear and mask define an adjustable closed loop. In some arrangements, the headgear can include one or more rigid portions that contact the user's face to at least partially isolate a seal of the mask from tightening forces applied to the headgear. In some arrangements, the mask is an oral-nasal mask and the headgear applies a force to the mask comprising an upward force component. In some arrangements, the headgear can be contoured to the user's head.Type: GrantFiled: June 26, 2023Date of Patent: March 18, 2025Assignee: Fisher & Paykel Healthcare LimitedInventors: Peter David Alexander Bearne, Roheet Patel, Kirstin Elizabeth Middelkoop, Fadi Karim Moh'd Mashal, Michael John Henri Cox, Blair Raymund Dadson Murphy

Patent number: 12232906Abstract: A method of determining a measure of wave speed or intensity in a fluid conduit uses ultrasound measurements to determine the conduit diameter and fluid velocity in a volume element, each as a function of time, and each at a same longitudinal position of the conduit. The ultrasound measurement to determine fluid velocity is effected by tracking objects within the fluid flow in successive frames sampling the volume element, and obtaining displacement vectors for the objects. A wave speed may be determined from a ratio of the change in fluid velocity at the longitudinal position as a function of time and the change in a logarithmic function of the conduit diameter as a function of time. A measure of wave intensity may be determined as a function of change in determined conduit diameter and corresponding change in fluid velocity.Type: GrantFiled: February 10, 2022Date of Patent: February 25, 2025Assignee: IMPERIAL COLLEGE INNOVATIONS LIMITEDInventor: Peter David Weinberg

Patent number: 12204648Abstract: Embodiments described herein are directed to transferring the ownership of a computing device from one entity to another entity. For example, a security processor is utilized to boot the computing device. During a boot session, the security processor loads and executes boot code, which determines whether specialized firmware authorized by the current owner indicates whether a transfer of ownership is to occur. In response to determining that the specialized firmware indicates that a transfer of ownership is to occur, the secure processor loads and executes the specialized firmware. The specialized firmware, when executed, causes the security processor to program a set of fuses with the public key of the new owner. Execution of the specialized firmware also causes the security processor to invalidate the public key of the original owner, which is stored in another set of fuses.Type: GrantFiled: December 22, 2023Date of Patent: January 21, 2025Assignee: Microsoft Technology Licensing, LLCInventors: Md. Nazmus Sakib, Bryan David Kelly, Ling Tony Chen, Peter David Waxman

Publication number: 20250023735Abstract: Methods, systems, apparatuses, and computer-readable storage mediums described herein enable executable code of a hardware security platform (HSP) circuit to communicate with a hypervisor in a separate processor. The hypervisor generates and manages virtual machines. The HSP code comprises trusted platform module (TPM) logic, that processes TPM commands received via the hypervisor, and in response to the processing, communicates security information (e.g., measurements, keys, authorization data) with the virtual machines via the hypervisor. The TPM logic receives security information related to a virtual machine from the hypervisor and stores the security information in non-volatile memory of the HSP circuit, where security information from a particular VM is distinguishable from security information from another VM in the HSP memory.Type: ApplicationFiled: August 23, 2024Publication date: January 16, 2025Applicant: Microsoft Technology Licensing, LLCInventors: Md.

Patent number: 12144674Abstract: A method of determining a measure of wave speed intensity in a fluid conduit uses ultrasound measurements to determine the conduit diameter, as a function of time, at a longitudinal position of the conduit, and to determine a measure of fluid velocity, as a function of time, in a volume element at said longitudinal position of the conduit. The ultrasound measurement to determine the measure of fluid velocity is effected by decorrelation of scattering objects within the fluid flow in successive frames sampling the volume element. A wave speed may be determined from a ratio of the change in fluid velocity at the longitudinal position as a function of time and the change in a logarithmic function of the conduit diameter as a function of time. A measure of wave intensity may be determined as a function of change in determined conduit diameter and corresponding change in fluid velocity.Type: GrantFiled: January 11, 2019Date of Patent: November 19, 2024Assignee: IMPERIAL COLLEGE INNOVATIONS LIMITEDInventor: Peter David Weinberg
