Abstract: An individualized therapy session can be delivered to a patient using a virtual reality headset and system. In one example, the system can include an accelerometer and a processor. The processor can receive data detected by the accelerometer. The data can include head position data and head movement data. The processor can then determine a view direction of a user of the VR device using the head position data, determine a heart rate of the user by using the view direction of the user to process the head movement data, and output the heart rate of the user to a remote device. The processor can receive, from the remote device, a command to adjust a VR session presented by the VR device to the user. Based on the command, the processor can adjust one or more parameters of the VR session presented by the VR device.

Abstract: Aspects and features of this disclosure relate to delivering individualized mental health therapies via networked computing devices. A mental-health-treatment-delivery server outputs a module with video content in connection with a mental health treatment protocol for a user. The mental-health-treatment-delivery server outputs a request for the user to respond to a question or to stimuli. The mental-health-treatment-delivery server receives a response from the user to the question or the stimuli. The mental-health-treatment-delivery server compares the response to stored data to determine information to present to the user. The mental-health-treatment-delivery server receives a command from the server device to present the information to the user. The mental-health-treatment-delivery server outputs the information to an interface of the user device.

Abstract: Described are systems and methods for communicating between a primary database and a standby database of a high availability data recovery (HADR) system. A plurality of primary partitions in a primary database and a plurality of standby partitions in a standby database are configured to communicate with each other. A transition of the plurality of primary partitions from a first HADR state to a second HADR state is synchronized.

Abstract: Techniques for initializing an arbitrary portion of memory with an arbitrary pattern includes using a memory controller for performing sequenced read and write operations. The memory controller receives address data, length data and pattern data on a data bus connected to a processor. The address data indicates a location in memory. The length data indicates an amount of memory to be initialized. The pattern data indicates a particular series of bits that is much shorter than the amount of memory indicated by the length data. The memory controller performs multiple write operations on memory beginning at a first location based on the address data and ending at a second location based on the length data. Each write operation writes the pattern data to a current location in memory, thereby initializing the arbitrary portion of memory with an arbitrary pattern based on the pattern data.

Abstract: There is disclosed a valve comprising a valve body, a bonnet, a bellows assembly and a translator assembly. The bellows assembly comprises a bellows and a bellows flange. The bellows flange is positioned between the bonnet and the valve body. The bellows flange defines a bellows flange opening, around which the bellows is attached. The translator assembly extends through the bellows flange opening. The bellows is attached to a periphery of the translator assembly. The invention also provides a power generating system comprising at least one turbine and at least one combustion system which comprises at least one fuel supply, at least one combustion canister, and at least one valve according to the present invention. There is also provided a method of constructing a valve.

Abstract: There is disclosed a valve comprising a valve stem threaded with a translator having a flow modulating region, in which rotation of the valve stem about its axis causes the translator to move axially relative to the valve stem. In one aspect, the threads on the translator and the valve stem threads have substantially similar coefficients of thermal expansion. In another aspect, a protrusion limits axial movement of the valve stem in one direction, the valve stem has at least one protuberance, at least one gland is engaged with the valve body, and at least one shim is positioned between the protuberance and the gland so as to limit axial movement of the valve stem relative to the valve body in an opposite direction. There are also disclosed power generating systems including such valves, and methods of constructing such valves.
