Abstract: Systems and methods for delta state tracking for event stream analysis. Events at a device are tracked and stored locally or forwarded to a server. The events collectively form an event stream. When an event of interest occurs, the precise configuration of a device at the time of the event of interest can be determined by applying the event stream in chronological or reverse chronological order to a snapshot of the device's configuration. Thus, the snapshot can be taken at any time. Tracking the deltas to the device's configuration enables the precise configuration at the time of the event of interest to be determined.

Abstract: An apparatus for calming a baby in an interior of a vehicle has a heartbeat sensor device (11, 12, 13) configured to capture a heartbeat input signal that depends on the heartbeat of an occupant in an interior (18) of a vehicle (10).

Abstract: An electronic device includes first device housing and a second device housing. The hinge housing is coupled to a first hinge arm extending into to the first device housing a second hinge arm extending into the second device housing. The first hinge arm has a first pin extending from a terminal edge of the first hinge arm that engages a first slot defined by a first bracket fixedly coupled to the first device housing. The second hinge arm has a second pin extending from a terminal edge of the second hinge arm that engages a second slot defined by a second bracket fixedly coupled to the second device housing. The first pin translates with the first slot and the second pin translates within the second slot, respectively, when the first device housing and the second device housing pivot to change a displacement between the hinge housing and the device housings.

Abstract: Disclosed are examples for providing functions to receive a media file to be stored in a media repository. In the examples, a location in the media repository may be assigned to the media file. A media file address in a blockchain platform may be assigned to the media file. Metadata including the assigned location in the media repository and the assigned media file address in the blockchain platform may be added to the media file. A media file hash value may be generated by applying a hash function to the media file including the metadata. The media file hash value may be included in a message and uploaded to the assigned media file address in the blockchain platform as a transaction in the blockchain. An indication that the media file is uploaded to the media repository may be delivered to a subscriber device from which the media file was received.

Abstract: A gas supply system for providing high pressure (HP) gas to a low pressure (LP) gas destination, having a primary HP gas unit and a reserve HP gas unit, which provide regulated lower-pressure gas to a supply manifold, and an LP destination regulator that provides an LP regulated gas supply to a consumption subsystem. A one-way flow valve in fluid communication from the primary HP gas unit to the reserve HP gas unit, ensures that the reserve HP gas unit remains substantially full, even after numerous cycles of depletion and replacement of the primary HP gas unit, during which the HP supply is provided by the reserve HP gas unit, which helps to avoid the risk that the reserve tank pressure and supply might mistakenly, unexpectedly or unintentionally be depleted.

Abstract: A grip assembly for an archery bow including an incrementally adjustable hand grip that can accommodate several customizable wrist positions for one or more archers without the use of separate attachments.

Abstract: Annotation techniques are implemented in an augmented reality environment. A user is presented with a GUI configured to place three-dimensional virtual annotations in an environment displayed via the user's computing device. The GUI presents a central GUI element that is center-locked with respect to the environment displayed via the user's computing device. The central GUI element is coplanar to a detected surface of the environment on which the central GUI element is virtually located. The annotation may be a three-dimensional arrow. While viewing the environment, a preview of the three-dimensional arrow pointing towards the central GUI element is presented to the user. Upon providing user input, the arrow is placed on the detected surface. The user may provide additional input that rotates the three-dimensional arrow around the central GUI element before placing the arrow.

Abstract: A power supply comprises voltage regulation circuitry, a load-share controller, and overcurrent protection circuitry. The voltage regulation circuitry is configured to output a regulated voltage. The load-share controller is configured to control the voltage regulation circuitry to adjust the regulated voltage responsive to a load-share voltage signal (LSV) that indicates an amount of load current being delivered to a load. The overcurrent protection circuitry is configured to selectively couple the regulated voltage to the load. When the load current exceeds a threshold current, the overcurrent protection circuitry is configured to decouple the regulated voltage from the load. While the regulated voltage is decoupled from the load, and when the LSV signal indicates that load current is being delivered to the load by a different power supply, the overcurrent protection circuitry is configured to recouple the regulated voltage to the load.
