  • Publication number: 20180047157
    Abstract: Systems and methods for identifying body joint location includes obtaining skeletal data, depth data and red, green, and blue (RGB) data pertaining to a user, obtaining, using input data, an estimate of body joint locations (BJLs) and body segment lengths (BSLs), iteratively identifying, based on the depth data and RGB data, probable correct BJLs in a bounded neighborhood around BJLs that are previously obtained, comparing a body segment length associated with the probable correct BJLs and a reference length, identifying candidate BJLs based on comparison, determining a physical orientation of each body segment by segmenting three dimensional (3D) coordinates of each body segment based on the depth data and performing an analysis on each segmented 3D coordinate. A corrected BJL is identified based on a minimal deviation in direction from the physical orientation of a corresponding body segment along with a feature descriptor of the RGB data and depth data.

  • Publication number: 20170296048
    Abstract: Disclosed herein is a system that uses an eye tracker for diagnosing and facilitating rehabilitation therapy of a patient suffering from disability. The system creates a human machine interface (HMI) that integrates various low cost biosensors and artificial sensors for conducting rehabilitation therapy. The system combines spinal and supra-spinal feedback of the patient with the operant conditioning to facilitate visuomotor balance therapy (VBT), thereby reducing fall risk in disability survivors. The operant conditioning setup for shaping of visuomotor learning to bring about new behavior or to modify a certain aspect of an existing behavior is used for rehabilitation therapy that includes a behaviour response apparatus, a reward delivery module, a stimulus delivery system, and a behaviour control system. The system can also be extended to the patient's home for providing telerehabilitation therapy.

  • Publication number: 20150281131
    Abstract: A system and method for providing multi-processor data plane architecture have been provided. The method comprises selecting several processing units for performing an egress data process and an ingress data process. A number of processing units are selected for performing an egress data process based on a type of switch and data rate. Several processing pipes are provided for each processing unit. Each processing pipe is divided into several processing stages based on a number of lookup tables used in the egress data process and the ingress data process to absorb a response time of a memory device. The data is stored in several databases in each processing unit, and the databases are copied into several banks to increase an access time with a storage device, such as DDR-SDRAM. Several headers are resynchronized using a fixed delay time through an ACL unit.
