  • Patent number: 9955880
    Abstract: A physiological parameter measurement device comprising a processor and a video processing module coupled to the processor to divide each of a plurality of frames of a video into a plurality of blocks, where the video is of a body part of a subject whose physiological parameter is to be determined. The video processing module further is to select a block having highest peak signal to noise ratio (PSNR) from amongst the plurality of blocks. Further, the video processing module is to extract a photoplethysmogram (PPG) signal from the video based on a block identifier associated with the block. The physiological parameter measurement device further comprises a signal enhancement module coupled to the processor, to process the PPG signal to obtain an enhanced PPG signal for determining a value of the physiological parameter for the subject.

  • Patent number: 9703582
    Abstract: A method or network system able to efficiently redistribute information, data, and/or context between virtual machines (“VMs”) using an in-memory file system (“IMFS”) is disclosed. After requesting memory access by an application program, a process of VM using IMFS is able to forward the memory allocation request from a VM kernel operating under a VM environment to an emulator. The emulator, which operates between the VM kernel and the hypervisor, again redirects the memory allocation request to the hypervisor for storage allocation. The hypervisor subsequently allocates at least a portion of storage space in the IMFS in accordance with the memory allocation request.
