Abstract: The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The invention disclosed is related to measurement of properties, particularly temperature (thermister), of gases flowing through a heated tube, supplying gases to a patient, which utilises the heating wire within the tube.

Abstract: A mill for the comminution of particulate material by impact means including a shell rotating at super critical velocity and a gyrating mandrel. Material introduced to the mill forms a bed on the inner surface of the shell and is then crushed by the impact of the gyrating mandrel. The axis of rotation of the shell is in angularly displaced from the axis of gyration of the mandrel to transport material through the mill.

Abstract: A breathing assistance apparatus user interface is described which presents animated information related to the management of the apparatus. The user interface is provided on a display screen of the apparatus. The animated illustrations can correspond to operational modes, warnings, user instructions, fault conditions, status, menu options, and the like. The animations can include a sequence of images shown in rapid succession which depict moving icons or objects, scrolling text, flashing colors, or any combination of these or the like. The user interface can combine static information along with animations.

Abstract: A technique for controlling access to one or more attractions is achieved using a number of access keys, each being issued to one or more users. An electronic queue management part manages a virtual queue in respect of each attraction and receives electronic requests for attraction access, each request relating to an access key and being for the users associated with it to access a particular attraction. Receipt of each request causes the respective users to be added to a corresponding virtual queue. A time at which each group of users reaches the front of the virtual queue and can access the attraction is determined. The users access the attractions by presenting an access key to an access control part, in communication with the electronic queue management part. Only a user presenting an access key at the correct time for accessing the attraction is allowed access to the attraction.

Abstract: A heat exchanger assembly that in a preferred embodiment comprises: an inlet duct lower wall interfacing with a bypass duct; an outlet duct lower wall interfacing with a bypass duct; a heat exchanger coupled between the inlet duct lower wall and the outlet duct lower wall wherein the heat exchanger is at a compound angle with respect to an inlet duct air flow direction; and a fairing coupled to the top of the heat exchanger wherein the fairing forms the inlet duct upper wall and the outlet duct upper wall.

Abstract: A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.

Abstract: The present invention relates to a process for preparing a tubular article, comprising (a) providing a carrier tube, (b) providing a metal coating on the carrier tube by applying a liquid metal phase onto the carrier tube and solidifying the liquid metal phase, (c) applying a contact pressure to the metal coating by at least one densification tool, and moving the densification tool and the metal coating relative to each other.

Abstract: A motor brush quick change assembly that includes brush units and electrical spring contacts. The brush units include a carrier with a housing and a brush. The electrical spring contacts are connected to an electrical device. Each of the brush units is configured to be removably attached to the electrical device to contact one of the electrical spring contacts. The brush unit thus provide for both a mechanical and electrical connection to the electrical device. The brush units are configured to prevent the need for separate electrical leads that require separate attachment and detachment to the electrical device. This design provides for straight-forward removal and replacement that can be performed by a robotic device or an operator.

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.

Abstract: A machine (1) for packaging an object, notably a sterilization basket (B), with at least one sterilization packaging material, notably a sterilization sheet (F), the machine comprising: a plate (10) configured to receive the sterilization packaging material (F) and the object to be packaged (B) placed on top, a gripping tool (110) configured to grasp hold of a corner (F1; F2; F3; F4) of the sterilization packaging material (F), the gripping tool (110) and the plate (10) being able to move relative to one another so as to allow the gripping tool (110) to bring the corner over the top of the object (B) and thus form at least one fold covering the object (B).

Abstract: The breathing assistance apparatus of the present invention includes a manifold that is provided with or retrofittable to gases supply and humidifying devices. The manifold allows gases from an oxygen concentrator to be combined with the flow through a gases supply and humidifying device, most usually air The combined output of oxygen and other breathing gases (air) is then humidified. The breathing assistance apparatus and manifold of the present invention provides a safe method to add oxygen to the input air stream of a gases supply and humidifying device and reduces the amount of accumulation of oxygen within the gases supply device, reducing fire risk should sparking occur within the device.

Abstract: A method, system, and preform for liquid forming of the preform into a final-shaped container using the liquid to be contained in the final-shaped container. The preform undergoes a stretching step to a size less than the size of a base of the final-shaped container, before being relocated and stretched to the final shape by the liquid. A stretch rod sealably connects with an interior surface of the preform to partially isolate a gate portion of the preform. The isolation is effected by a portion of the inner surface of the preform extending inwardly, or by a deformable member on the stretch rod which can selectively extend outwardly to contact the interior surface of the preform. The stretch rod includes a selectively heatable tip to heat the gate portion of the preform. The gate portion of the preform includes inner, outer, and core layers which comprise a material configured to affect the thermal properties of the gate portion.

Abstract: Systems and methods for generating and validating certified electronic credentials are disclosed. A publisher may receive a certified electronic credential order from a credentialer and prepare a plurality of certified electronic credentials. The publisher may associate each credential with authentication information and a credential record, and retain a database of associated authentication information and credential records. The publisher may provide validation services, receiving a validation request through a credentialer's validation portal, and provide a response through the credentialer's portal indicative of the validity, additional information about the credential and/or the credential holder. The credential holder may assign a personal access key to control or limit the validation of a credential. A validating entity may receive credential validation through the credentialer with a heightened degree of confidence in the validation and lack of forgery.
