Patent number: 10463820Abstract: Systems, methods, and/or apparatuses for acclimatizing a user to positive airway pressure (PAP) therapy are provided. Generally, a sub-therapeutic treatment pressure is provided initially. It may be ramped up to a full treatment pressure over the course of one or more therapy sessions. The pressure level may be ramped up based on, for example, sleep state, sleep phase, patient compliance with types of treatment (e.g. bilevel vs. CPAP, etc.), clinician input (either at the site, remotely, via pre-programmed smartcards, etc.), etc. Such techniques may be used alone or in combination.Type: GrantFiled: August 11, 2016Date of Patent: November 5, 2019Assignee: ResMed Pty LtdInventors: David Mulcahy, Philip Kwok, William Mcinnes Somerville, David Vorreiter

Publication number: 20070261697Abstract: A nasal cushion (30) comprises a substantially triangularly frame (32) from which extends a membrane (34). The frame (32) has a scalloped edge (36) by which the cushion (30) is affixed to a mask body. The member (34) has an aperture (38) into which the wearer's nose is received. The membrane (34) is spaced away from the rim (40) of the frame (32), and its or surface (41) is of substantially the same shape as the rim (40). Respective notches (42,44) receive the bridge of the wearer's nose. The wearer's nose is received through the aperture (38) into the chamber within the mask body (46). The seal forming portion (45) thus contacts both the surface of the wearer's nose and a portion of the wearer's face in the region between the base of the nose and the upper lip, and around the sides and over the bridge of the nose. The shape of the seal forming portion (45) is particularly suited to effectively seal the difficult region of the facial contour that is the crease between the sides of the nose and the face.Type: ApplicationFiled: July 13, 2007Publication date: November 15, 2007Applicant: ResMed LimitedInventors: Philip Kwok, Robert Styles

Patent number: RE42335Abstract: A low-dropout regulator with a single-transistor-control providing improved transient response and stability is disclosed. The single-transistor-control provides a dynamic resistance at the output of the regulator for minimizing undershoot and overshoot, and hence improves transient response. Since the single-control transistor reduces the output resistance of the regulator, the output pole is pushed to a sufficiently high frequency without affecting stability. Therefore, the limited choice of combinations of the output capacitance and its equivalent-series-resistance is substantially relaxed.Type: GrantFiled: October 23, 2009Date of Patent: May 10, 2011Assignee: The Hong Kong University of Science and TechnologyInventors: Tsz Yin Man, Chi Yat Leung, Ka Nang Leung, Philip Kwok Tai Mok, John Man Sun Chan
