Abstract: This disclosure includes plunger pumps having leak detection systems. Some pumps include a housing having a bore, an inlet, and an outlet, a plunger disposed within the bore and a first seal engaged with the plunger to divide the bore into first and second chambers, the plunger configured to reciprocate within the bore to expel liquid from the first chamber out of the outlet, and a sensor for detecting a presence of liquid in at least a portion of the second chamber. Some pumps have a reservoir for collecting liquid that leaks into the at least a portion of the second chamber, where the sensor is for detecting a liquid level in the reservoir. Some pumps include a second seal engaged with the plunger to divide the second chamber into first and second portions, and the sensor is for detecting a presence of liquid in the second portion.

Abstract: In a preferred embodiment, systems and methods for delivering oxygen to a passenger of an aircraft via an oxygen mask having one or more sensors involve analyzing blood oxygen saturation measurements from the sensor(s) to determine a current oxygen saturation level, determining the current oxygen saturation level is insufficient, and adjusting an oxygen flow rate to the mask to compensate for the current blood oxygen saturation level.

Abstract: Techniques are described for enabling users of a cloud provider network to launch compute instances with the option to dedicate networking paths between the compute instances in an otherwise shared networking environment. A user can send, for example, a request to launch two or more compute instances, where the request further indicates a request for a dedicated networking path between the instances. A hardware virtualization service launches the requested compute instances and further sends signals to the computing devices at which the instances are launched indicating the request for a dedicated networking path. A computing device, upon receiving such a signal for a hosted instance, configures routing information at the computing device to dedicate, to the identified instance, an available network link accessible to the computing device and further propagates the signal to additional networking devices as needed to form a dedicated networking path between the associated compute instances.

The cantilever spring may have a spring bearing face, and the cantilever spring may apply a force to the cupholder member pivot portion. The resettable cupholder apparatus may be in a stowed position when the spring bearing face is located in the stowed detent. The resettable cupholder apparatus may be in a deployed position when the spring bearing face is located in the deployed detent.

Abstract: In one embodiment of an aircraft emergency oxygen delivery system, power can be generated by the flow of gas over a transducer disposed inside an oxygen delivery tube. A pressure differential gives rise to a temperature difference across the transducer, and the temperature difference can be converted to a voltage. The voltage can be quadratically dependent upon the Mach number M (e.g. flow velocities from 1 to 140 m/s) and proportional to a Seebeck coefficient of the transducer. The power thus generated may be used to operate LED indicators visible from the exterior of the tube, a variety of sensors, and wireless communication with a central control system. Oxygen flow to a mask may be adjusted based on ambient oxygen content and data collected from a passenger wearing the mask, including a blood oxygen saturation level, pulse or respiration rate.

Abstract: Examples described herein generally relate to displaying an image on a display device where a motion during a latency between a first time associated with activating a first portion of the display device and a second time associated with activating a second portion of the display device is predicted. At least a second portion of an image, to be displayed at the second time, is distorted based at least in part on a function of the motion and the latency to compensate for the latency. A first portion of the image is displayed at the first time by activating the first portion of the display device. The second portion of the image, as distorted, is displayed at the second time by activating the second portion of the display device.

Abstract: Methods and devices for managing first-in first-out (FIFO) queues in graphics processing are described. A write operation can be executed by multiple write threads on a graphics processing unit (GPU) to write data to memory locations in the multiple pages of memory. Similarly, and/or simultaneously, a read operation can be executed by multiple read threads to read data from the memory locations. The write and read operations include updating a pointer or multiple pointers indicating the point at which all preceding data has been fully written, or fully read. The read and write operations can also include maintaining and advancing one or more allocation pointers, and performing comparisons with the read and write done pointers, and/or various methods of synchronization, to handle overflow and underflow scenarios, to ensure read operations only read valid data, and write operations do not attempt to write to locations which are already in use.

Abstract: Examples described herein generally relate to performing frame extrapolation in image frame rendering. A vertex mesh as a set of vertices is generated, and each vertex is mapped to a screen space position for defining a texture. One or more motion vectors for one or more regions in a first image frame of a stream of image frames can be determined. The screen space positions associated with at least a portion of the set of vertices within the texture can be modified based at least in part on the one or more motion vectors. A graphics processing unit (GPU) can render the first image frame into the texture. The extrapolated image frame is displayed after the first image frame and before a next image frame in the stream of image frames.

Abstract: Methods and devices for processing image frames is described. The techniques presented herein leverage known characteristics of the optical transfer component in order to modify the resource allocation for rendering the subset of pixels whose contribution to the final rendered image is less than a contribution threshold. Thus, in situations where the deflection of light from the lens may impact the contribution of the one or more subset of pixels of an image frame towards the final rendered image, the image processing techniques presented here may either omit or deprioritize the identified subset of pixels in order to conserve valuable resources (e.g., dedicate less processing time and memory to rendering the identified subset of pixels).
