US Classification:

2502081, 2502082, 382199, 348371

Abstract:

A camera includes a set of sensing elements. Each sensing element is arranged at an image plane in an energy field to measure a magnitude and sign of a local gradient of the energy field. Each sensing element includes at least two energy intensity sensors. Each energy sensor measures a local intensity of the energy field. Logarithms of the intensities are subtracted from each other to obtain the magnitude and sign of the gradients. A Poisson equation is solved using the gradients to obtain an output image of the energy field.

Abstract:

A system including a reference data server that stores a first set of data used in the plurality of processes, a load balancer that reconfigures the transactional data, a first stage processing system and a second stage processing system. The first stage processing system includes one or more first processing modules that execute at least one process of a first set of the plurality of processes on the reconfigured transactional data to generate first stage processed transactional data, each of the one or more first processing modules comprising an in-memory cache that stores a second set of data used in the at least one process, and a first stage data storage system that stores the first stage processed transactional data. The second stage processing system includes one or more second processing modules that execute at least one process of a second set of the plurality of processes on the first stage processed transactional data to generate second stage processed transactional data, each of the one or more second processing modules comprising an in-memory cache that dynamically stores a third set of data related to the at least one process, and a second stage data storage system that stores the second stage processed transactional data.
