Abstract: A command processing method to reduce a system delay and system complexity while ensuring system consistency. A server receives from a client a target request that carries a target command. The server uses a current time as a target timestamp of the target request, adds a local associated command corresponding to the target context number and a local conflicted command corresponding to the target command to a target dependency set, and forwards the target request to a replica server. The server updates the target dependency set according to a feedback from the replica server, and stores an updated target dependency set synchronously with the replica server. And the server determines a target execution sequence of the target command and each command in the updated target dependency set.

Abstract: An image sensor includes a time-resolving sensor and a processor. The time-resolving sensor outputs a first signal and a second signal pair in response detecting one or more photons that have been reflected from an object. A first ratio of a magnitude of the first signal to a sum of the magnitude of the first signal and a magnitude of the second signal is proportional to a time of flight of the one or more detected photons. A second ratio of the magnitude of the second signal to the sum of the magnitude of the first signal and the magnitude of the second signal is proportional to the time of flight of the one or more detected photons. The processor determines a surface reflectance of the object where the light pulse has been reflected based on the first signal and the second signal pair and may generate a grayscale image.
