Patent CA-2271469-A1 (CA)
Title: Self contained breathing apparatus
Inventor: GIORGINI EUGENE
IPC: A62B7/02
Filed: 1998-03-27
Abstract: A self contained breathing apparatus (10, 130) includes a pressure vessel (12) which holds a supply of breathing air. The pressure vessel is in fluid communication through a first stage pressure regulator (22) with a second stage breathing regulator (40). The breathing regulator is operatively connected to a face mask (42) which is worn by a user. When the pressure available in the supply is at a suitable pressure pressure regulator (22) provides pressure to breathing regulator (40) at a first pressure. When the pressure in the supply falls to a value indicative of impending depletion of the air supply, a transfer piston (94) in a step up valve (24) shifts. A change in condition of the step up valve causes a step up piston (127) to increase the output pressure from regulator (22). This increased pressure moves a sensing piston (60) and causes indicating devices (68, 78) in an alarm circuit (64) to be activated. In alternative embodiments, an electronic alarm module (132) is used to provide indications of the impending depletion of the air supply.

Title: Surgical navigation system and method using audio feedback
Inventor: KARRON DANIEL B
IPC: A61B17/00
Filed: 1998-01-21
Abstract: A computer based system and method is disclosed for positional guidance in real-time surgical applications using audio feedback. The invention is based on translating the 5 spatial parameters of a surgical instrument or device, such as its position and velocity with respect to a given coordinate system, into a set of audio feedback parameters along the coordinates of a generalized audio space. Error signals which correspond to deviations of the actual instrument trajectory from an optimal trajectory stored in a computer memory are translated into a set of audio signals that indicate to the user whether correction is required. Accordingly, the system and method can be used in a variety of applications that require accurate special positioning. The audio feedback system and method of this invention employ a rich and comparatively unburdened sensory modality in the operating room and can be practiced independent from or along with standard visually-oriented systems and techniques used in medical pre-planning and/or virtual reality devices.
