Abstract: A track tension system including a hydraulic cylinder coupled between a drive frame and idler of a track system, an accumulator and a hydraulic valve that controls flow between the cylinder and accumulator. The cylinder extends and retracts to change the distance between the drive frame and idler which increases and decreases, respectively, tension on the track system. The hydraulic valve can be opened to allow flow between the cylinder and accumulator, and closed to block flow between the cylinder and accumulator. Control factors can be monitored to control valve position. An overload pressure relief can allow flow between the cylinder and accumulator when the hydraulic valve is closed and pressure in the cylinder reaches overload pressure. An orifice can allow constricted flow between the cylinder and accumulator when the hydraulic valve is closed. A check valve can connect the track tension system to a vehicle hydraulic system.

Abstract: Systems, apparatus, and methods for providing humidity in a positive airway pressure (PAP) device. In one embodiment, a humidifier is configured to periodically provide vapor to a flow of pressurized gas to produce flows of pressurized gas with added humidity. Each of the flows of pressurized gas with added humidity may be timed to reach a user interface primarily during a first portion of a breath cycle (e.g., during inspiration). Portions of the flow of pressurized gas that reach the user interface during a second portion of the breath cycle (e.g., during expiration) may include little or no added humidity.

Abstract: An apparatus and method for synchronized content display across a plurality of devices are disclosed herein. Content specified at a first device is deployed to the rest of the plurality of devices that are of diverse device types to each other. The first device instructs the other devices to render the content at each of the respective devices according to the respective device's content viewer and configuration. The first device also instructs the other devices to achieve a certain setting or state pertaining to true rendering of the content depending on the type of content to be rendered.

Abstract: An apparatus and methods for the administration of positive airway pressure therapies. The apparatus can include a housing, a blower and a mask. The housing is configured to be stably secured on the head of a patient. The blower is secured relative to the housing. A mask in fluid communication with the blower is configured to communicate pressurized air produced at least in part by the blower to the airways of a user.

Abstract: A respiratory therapy apparatus that introduces water into the pressurized air delivered to a user during various positive airway pressure therapies and corresponding methods. The respiratory therapy apparatus may be configured to administer one or more positive airway pressure therapies, including: continuous positive airway pressure therapy (CPAP), hi-level positive airway pressure therapy (BPAP), auto positive airway pressure therapy (autoPAP), proportional positive airway pressure therapy (PPAP), and/or other positive airway pressure therapies. The respiratory therapy apparatus may include a user interface that defines an interface passage to communicate pressurized air to the user for inhalation and a humidifier that introduces water into the pressurized air generally at the interface passage. Methods may include introducing water into the interface passage at one or more humidifier ports disposed about the interface passage.

Abstract: Elements of the geometry of the image of a webpage as rendered on at least one target browser are compared with elements of a baseline geometry of the webpage to determine the differences between elements of the baseline geometry of the webpage and elements of the respective geometries of the image of the webpage as rendered on the at least one target browser. The elements of the image may be determined by a software tool for determining elements of a document geometry, such as a DOM geometry service. Code such as JavaScript may be injected into the webpage for use in determining the elements of the geometry of the image of the webpage. A list of issues that web developers face may be generated and the above differences between respective elements may allow arriving at a solution for at least some of the issues in order to provide testing of webpage information in real time.

Abstract: An apparatus and method for automatically inventorying a plurality of devices is disclosed herein. A secure, trusted connection is established between a remote device each device of a plurality of devices. The remote device automatically extracts device information from each device of the plurality of devices. The remote device creates an inventory of the plurality of devices based on the extracted device information. The remote device automatically maintains the inventory including automatically extracting at least updated device information associated with an update event of the first device.

Abstract: In one embodiment, a method of connecting to a client computing device is provided. The method is performed at a computing device, and in this method a connection is made to the client computing device. An inventory of the client computing device is then accessed. This inventory is stored in a storage device accessible by way of a computer network. Here, the storage device is separate from the client computing device and the computing device. A connection failure between the computing device and the client computing device is detected and thereafter, the inventory from the storage device is retrieved by way of the computer network. A reconnection to the client computing device can then be made based on the retrieved inventory.
