Abstract: The End-to-End Encryption and Hot Wallet Key Recovery Apparatuses, Processes and Systems (“E2EEHWKR”) transforms key backup request, key recovery request datastructure/inputs via E2EEHWKR components into key backup response, key recovery response outputs. A key backup request datastructure specifying a wallet private key, a private key backup server identifier, a PIN shard fracture scheme definition, and a plurality of PIN shard backup devices is obtained. A user security PIN is obtained and utilized to encrypt the wallet private key. A symmetric key is calculated from a public key associated with the private key backup server identifier and an app private key. The encrypted wallet private key is encrypted utilizing the symmetric key. The twice encrypted wallet private key is sent to a private key backup server. The user security PIN is encrypted utilizing an asymmetric keypair. Encrypted user security PIN shards are generated and sent to PIN shard backup devices.

Abstract: Automatic dry sprinkler assemblies for fire protection systems. Preferred embodiments of the automatic dry sprinkler assemblies include a tubular outer housing having an inlet, an outlet opening, and an internal surface configuration proximate the outlet opening that defines an internal landing surface and a cantilevered centering wall. A fluid deflection member is spaced from the outlet opening along a fluid flow path of the assembly. A fluid control assembly disposed within the outer housing for axial translation from an unactuated state to an actuated state of the sprinkler assembly to control fluid flow from the inlet to the outlet for fluid discharge along the fluid flow path to the deflection member. The internal landing surface and cantilevered centering wall are axially spaced from one another proximate the outlet opening to circumscribe and confront components of the fluid control assembly to facilitate centering and axial translation of the fluid control assembly.

Abstract: Systems for transitioning a user interface arrangement from a display of a two-dimensional image of a user to a rendering of a three-dimensional representation of the user is provided. A system can start with a UI including a rendering of a user that is based on a 2D image file.

To display the rendering of the 3D representation of the select user, the system uses permission data and a three-dimensional model defining a position and orientation to display the 3D representation of the user. The system allows users to switch between viewing modes to allow users to interact with content using the most effective type of hardware.

Abstract: A smartphone casing with an LED flashlight unit and battery pack. The casing is sized to partially encapsulate the shell of a smartphone. The back wall includes an LED light unit coupled to a battery pack. An LED activation button provides a direct coupling between the battery pack and the LED light unit. The power pack independently stores electrical power in its lithium-ion pack. There are 5 sequential modes. The first three modes initiate light emission at 600* lumen, 400* lumen and 200* lumen. The fourth mode is termed a Strobe Self-Defense to stifle and hinder an assailant in a hostile situation. The fifth mode is a Beacon to give a signal of emergency.

Abstract: System and methods to provide ceiling-only suppression fire protection of up to fifty feet (50 ft.) of rack storage of cartoned unexpanded plastic commodities and less hazardous commodities, such as for example, Class 1, Class 2, Class 3, Class 4 and/or combinations thereof beneath a ceiling having a maximum ceiling height up to fifty-five feet (55 ft.). The systems and methods provide for hydraulic and system parameters that include a hydraulic design area based upon five to no more than twelve hydraulically most remote sprinklers spaced at a preferred sprinkler-to-sprinkler spacing of eight to ten feet (8-10 ft.) coupled to two to four branch lines tied to a common cross main supply pipe of firefighting fluid.

Abstract: This disclosure describes, in part, devices and methods for deactivating tags. For instance, an electronic device may include antennas that transmit signals and/or fields for deactivating the tags. In some examples, the electronic device includes a first gate that includes a first portion of the antennas and a second gate that includes a second portion of the antennas. To deactivate the tags, the electronic device may detect locations of an object relative to the electronic device. The electronic device may then activate a respective tag and/or a respective group of tags based on the location of the object. For example, the electronic device may activate a first tag and/or a first group of tags when the object is at a first location, activate a second tag and/or a second group of tags when the object is at a second location, and/or so forth.

Abstract: A system provides automated transitions between presenters of a communication session. During a meeting, a system can provide a user interface that includes a primary presenter region configured to display a rendering of a presenter and the presenter's shared content. When the system determines that an individual raises their hand, either by a video input gesture or a button selection, the system automatically add a video stream of that individual in a secondary display region, and also displays an ordered queue of presenters. The system can also automatically change permissions for users that initiate a transition to a presenter role.

Abstract: A laminated glass article comprises a core layer comprising a core glass composition having an average core coefficient of thermal expansion (CTEcore) and a clad layer directly adjacent to the core layer and comprising a clad glass composition having an average clad coefficient of thermal expansion (CTEclad) that is less than the CTEcore such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer increases with increasing distance from the outer surface of the clad layer, transitions to a minimum tensile stress as a step-change at an interface region between the core layer and the clad layer, and a magnitude of the tensile stress increases continuously to a maximum tensile stress in the core layer. Other stress profiles, and methods of preparing laminated glass articles are also disclosed.
