    Abstract: Disclosed is a method of providing a proximity warning using a head-worn device. A distance is determined between the head worn device and a relevant object, such as a cyclist, jogger or vehicle, using image-processing techniques. A speed of the head-worn device is determined using a GPS receiver or other position components located in the head-worn device or an associated user-device. A braking distance for the head-worn device is determined based on the speed of the head-worn device, and compared to the distance to the relevant object. A warning notification is provided by the head-worn device if the distance to the relevant object is less than the braking distance.

    Abstract: Systems, methods, and computer readable media for decentralized two-phase commit in a datastore or database where the methods include determining pre-validating a transaction, writing first metadata to a leader partition, the first metadata including a state indicating preparing and mutations of the transaction, and writing second metadata of a follower partition to indicate the follower partition is locked by the leader partition. The methods further include updating the state of the first metadata to indicate committed and performing the transaction on the leader partition, performing the transaction on the follower partition and unlocking the follower partition, and updating the first metadata to remove the mutations of the transaction and updating the state of the first metadata to indicate the transaction is completed. The methods may further include selecting a leader partition key and updating the state of the first metadata to indicate committed unapplied.

    Abstract: Systems and methods herein describe a system for context triggered augmented reality. The proposed systems and methods receive first user input indicative of a selection of a user interface element corresponding to a recipient user, generate an augmented reality content item based on second user input from the first computing device, generate a contextual trigger for the generated augmented reality content item, the contextual trigger defining a set of conditions for presenting the generated augmented reality content item on a second computing device, generate a multi-media message comprising audio data recorded at the first computing device, detect at least one condition of the set of conditions being satisfied, and in response to detecting at least one of the set of conditions being satisfied, causing presentation of the augmented reality content item and the multi-media message at the second computing device.

    Abstract: Methods and systems are disclosed that access relationship data of a first user of an interaction system to identify a second user of the interaction system associated with the first user, cause presentation of identification information for the second user within an interaction interface and, responsive to identifying an event pertaining to the second user, cause presentation of a call-to-action graphical element associated with identification information of the second user within the interaction interface. Responsive to detecting user selection of the call-to-action graphical element, the methods and systems invoke an interaction function to facilitate an interaction between the first user and the second user. The interaction function includes at least one of a communication function enabling the first user to communicate digital content to the second user using the interaction system, and an augmentation function enabling the first user to augment the digital content using an augmentation graphical feature.

    Abstract: A system, circuit, and method for implementing a low power common electrode voltage for a display (e.g., LcoS display) having transistors with low to moderate breakdown voltages may include a first and a second low voltage amplifier, wherein the first amplifier generates a pixel voltage and the second amplifier generates a predetermined voltage. The circuit may include a common electrode circuit coupled to the first and second amplifier to generate a common electrode voltage. Particularly, the circuit may include a control circuit coupled to the common electrode circuit, wherein, during a first phase, the control circuit selectively controls the common electrode circuit to generate a low common electrode voltage based upon a negative value of the predetermined voltage. Further, during a second phase, the control circuit selectively controls the common electrode circuit to generate a high common electrode voltage based upon the sum of the predetermined voltage and the pixel voltage.
