  • Patent number: 11600084
    Abstract: A method of price text detection by an imaging controller comprises obtaining, by the imaging controller, an image of a shelf supporting labels bearing price text, generating, by the imaging controller, a plurality of text regions containing candidate text elements from the image, assigning, by the imaging controller, a classification to each of the text regions, selected from a price text classification and a non-price text classification. The imaging controller, within each of a subset of the text regions having the price text classification: detects a price text sub-region and generates a price text string by applying character recognition to the price text sub-region. The method further includes presenting, by the imaging controller, the locations of the subset of text regions, in association with the corresponding price text strings.

  • Publication number: 20220354377
    Abstract: Provided are a wearable device, as well as a heart rate tracking method and a heart rate tracking apparatus thereof. The method includes obtaining a photo pethysmo graphic (PPG) signal of the wearable device within a preset time, obtaining a frequency spectrum corresponding to the PPG signal by a short-time Fourier transformation of the PPG signal, generating a curve cluster according to the frequency spectrum, and in response to determining a curve that meets a preset condition in the curve cluster, acquiring a jumped heart rate according to the curve that meets the preset condition to track the heart rate.

  • Publication number: 20210106257
    Abstract: The present disclosure provides a wearable device, a signal processing method and a signal processing apparatus, the signal processing method is applied to the wearable device, the wearable device is provided with a biosensor and a motion detector group, and the signal processing method includes the following steps. The human physiological signal collected by the biosensor is acquired, the human physiological signal is divided into multiple signal frames, each of the multiple signal frames corresponds to the time range; for each signal frame, it is determined whether the user wearing the wearable device is in the body motion state according to the body motion signal collected by the motion detector group within the time range corresponding to the signal frame, and when the user wearing the wearable device is not in the body motion state, the signal frame is stored into the preset buffer.

  • Patent number: 8647278
    Abstract: Disclosed embodiments include a system and a method for determining intracranial pressure (ICP) of a subject that comprises: (a) applying transcranial Doppler (TCD) to determine the middle cerebral artery (MCA) velocity of the subject and estimating changes in the ICP continuously based on a functional mapping that relates arterial blood pressure (ABP) and cerebral blood flow velocity (CBFV) to ICP, resulting in an estimated ICP trend; (b) generating a flash visual evoked potential (FVEP) on the subject, processing a detected FVEP signal and obtaining an estimated ICP; and (c) combining the estimated ICP trend from TCD CBFV and ABP with the estimated ICP obtained by signal processing of the detected FVEP signal to periodically correct the trend and obtain a non-invasive measure of ICP.

  • Patent number: 6001510
    Abstract: The present invention provides a method for producing double-card anti-counterfeit marks with interlock protection based on the technique which combines nuclear technology with computer-generated hologram (CGH) technology and inspecting apparatus for the mark. The invention relates to the technical field of optical information processing in physics. The technical feature of the invention is to insert potential images R,T and matched potential images R',T' in the anti-counterfeit identification marks and in the inspecting identification marks respectively by means of charged particle track image in sampling coincidence with CGH. When R coincides with R', a certain message of genuineness for an identification mark will be shown, and when T coincides with T', different specific information in thousands of ways appears to prove the genuineness of the protected objects.
