Abstract: Described herein are battery modules and methods of fabricating thereof. In some examples, a battery module comprises an enclosure, separated into two enclosure portions and a thermal portion, positioned between the two enclosure portions. Two enclosure portions are in part defined by side walls, which can be tapered. The thermal portion comprises two thermal walls, which are operable as the bottoms of the two enclosure portions and form a thermal cavity between these thermal walls. In some examples, the enclosure is a monolithically cast component. Alternatively, the enclosure can be partially cast with one thermal wall welded thereafter to a cast subassembly. The battery module also comprises two sets of batteries, each positioned into a corresponding enclosure portion. Each battery set is interconnected with an interconnecting assembly, positioned between the battery set and the corresponding cover, for this enclosure portion.

Abstract: Described herein are battery packs and electric vehicles using these packs. In some examples, a battery pack comprises two portions/covers and a set of battery modules positioned within the enclosed cavity formed by these portions. A battery pack may comprise a set of pressure-relief valves positioned in and protruding through a wall of at least one portion. Each valve can be coaxial with a corresponding gap provided between two adjacent modules. The valve is configured to provide a fluid path (to the exterior of the battery pack) when the pressure inside the pack exceeds a set threshold. In some examples, the battery pack comprises an inlet tube fluidically coupled to the inlet port of each module and an outlet tube fluidically coupled to the outlet port of each module. A set of specially configured orifices or controllable valves is positioned on the fluid path through each module.

Abstract: A program is executed using a call stack and shadow stack. The call stack includes frames having respective return addresses. The frames may also store variables and/or parameters. The shadow stack stores duplicates of the return addresses in the call stack. The call stack and the shadow stack are maintained by, (i) each time a function is called, adding a corresponding stack frame to the call stack and adding a corresponding return address to the shadow stack, and (ii) each time a function is exited, removing a corresponding frame from the call stack and removing a corresponding return address from the shadow stack. A backtrace of the program's current call chain is generated by accessing the return addresses in the shadow stack. The outputted backtrace includes the return addresses from the shadow stack and/or information about the traced functions that is derived from the shadow stack's return addresses.

An example co-polymer includes H2DPP-co-ProDOT. The related synthesis pathway displays significant simplicity and eliminates needs for reaction pathways, reagents, conditions, and the like associated with waste, toxicity, and other undesired properties.

Abstract: A glass including silica and titania is disclosed. An average hydroxyl concentration of a plurality segments of the glass is in a range from about 20 ppm to about 450 ppm, an average titania concentration of the plurality of segments is in a range from about 6 wt. % to about 12 wt. %, and each segment of the plurality of segments has a length of about 12.7 mm, a width of about 12.7 mm, and a height of about 7.62 mm. The hydroxyl concentration of each segment is measured using a Fourier transform infrared spectroscopy in transmission, the refractive index is measured using an optical interferometer with a 633 nm operating wavelength and a resolution of 270 microns×270 microns pixel size, and the average titania concentration is determined based upon the measured refractive index.

Abstract: The techniques herein are directed generally to a “zero-knowledge” data management network. Users are able to share verifiable proof of data and/or identity information, and businesses are able to request, consume, and act on the data—all without a data storage server or those businesses ever seeing or having access to the raw sensitive information (where server-stored data is viewable only by the intended recipients, which may even be selected after storage). In one embodiment, source data is encrypted with a source encryption key (e.g., source public key), with a rekeying key being an encrypting combination of a source decryption key (e.g., source private key) and a recipient's public key. Without being able to decrypt the data, the storage server can use the rekeying key to re-encrypt the source data with the recipient's public key, to then be decrypted only by the corresponding recipient using its private key, accordingly.

Abstract: An apparatus for generating and providing a pressurized breathable gas to a patient's airways includes a respiratory pressure therapy (RPT) device having an engagement port pneumatically and electrically coupled to the RPT device, and an air delivery tube configured to engage the engagement port so as to pass a flow of breathable gas to a patient interface. The air delivery tube includes electric contacts associated with a heating and/or a sensing arrangement. The air delivery tube includes a locking collar rotatably movable between (1) an unlocked position to allow connection/disconnection of the air delivery tube to/from the engagement port, and (2) a locked position to releasably lock the air delivery tube to the engagement port. The air delivery tube is structured and arranged to, when the locking collar is rotated into the locked position, pneumatically connect to the engagement port and define an operational configuration of the apparatus.

Abstract: Methods and systems employing augmented reality techniques via real-world objects for various purposes. Computer implemented methods are provided for animated augmentation of real-time video of static real-world objects. A computing device receives first data defining features and movements of a human subject, captures a video image of an object having features corresponding to human features, maps features defined by first data to corresponding features of the object, and uses the first data to animate the corresponding features of the object to correspond with the movements of the human subject defined by the first data. The object may be a physical 3D object. Embodiments may include positioning and orienting a 3D mesh representation of the object in registration with the object video image, prior to mapping the features defined by the first data to corresponding features on the 3D mesh. Recorded audio messages may be played in synchronism with the object.
