Abstract: A temperature control unit may include one or more thermoelectric cooling elements coupled to a conditioned space heat exchanger and an unconditioned space heat exchanger. The unit may further include one or more conditioned air fans configured to move air from a conditioned space over the conditioned space heat exchanger. The unit may also include one or more unconditioned air fans configured to move air from an unconditioned space over the unconditioned space heat exchanger. The unit may further include a power supply configured to change a polarity and level of power to the one or more thermoelectric cooling elements.

Abstract: A system, method, and article of manufacture for facilitating the administration of physical therapy to a patient located remotely from a prescribing therapist in which a processing device instructions is adapted to providing to the patient an instructional exercise video(s) related to a prescribed exercise regimen; track in three dimensions movement of the patient's body or body parts using a motion sensing device when the movement is related to the prescribed exercise regimen; and provide information related to the movement to the prescribing therapist located at location remote from the patient.

Abstract: A swivel elbow includes a conduit pathway separated from a vent airflow pathway for conducting respective gas flow streams in use. The swivel elbow further includes baffle structure that separates the respective gas flow streams so that they do not interfere with each other within an interior (e.g., breathing chamber) of a mask to which the elbow is connected in use.

Abstract: A forehead pad for use in a respiratory mask with a forehead support, which includes a base portion to contact a user's forehead, a support post connected to the base portion, and a head adapted to connect the support post to a forehead support. A pair of forehead pads may be joined with a connector.

Abstract: A variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.

Abstract: A mask system for treating sleep disordered breathing, comprising headgear, a shell/cushion including a channel adjacent a front aperture, a frame, an elbow including at least one undercut on a proximal end, a retaining ring including a rear flange adapted to be retainably insertable in the channel of the shell/cushion, and a front flange adapted to retainably engage with the at least one undercut of the elbow.

Abstract: A double-ended variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the double-ended blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.

Abstract: A multiple stage variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the multiple stage blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.

Abstract: A respiratory mask assembly for use in the delivery of non-invasive positive airway pressure to a user. The assembly includes a rigid shell having a channel portion defined by an inner wall, an outer wall and a channel floor, a face-contacting cushion acting to space the shell away from the user's face and a sealing tab extending from the cushion to engage a portion of the shell to provide a continuous airtight seal between the cushion and the shell. A retaining ring within the mask assembly is configured to secure the cushion to the shell. The retaining ring has a first portion including at least one clip configured to pass through at least one slot portion such that an underside surface of the at least one clip engages a section of the shell when the retaining ring is positioned within the channel.

Abstract: A multi-story transverse shifting type automatic parking device is described which is suited for a multi-story parking building. Each floor of the building is divided into at least one row of equal blocks, each row of equal blocks being formed with an elevator passage way centrally located and at least two parking units on the opposite sides of the elevator passage way. At least one lifting gearframe is installed in the elevator passage way and is driven horizontally from one row to another with a lifting gear mainframe which includes a mother elevator driven vertically and a multi-story daughter elevator driven to move vertically in the mother elevator. A plurality of pairs of transverse shifting mechanisms respectively fastened in each floor of the building are provided and each pair of which are fastened at opposite sides of the elevator passage way.
