  • Patent number: 11067673
    Abstract: Techniques of designing an image sensor particularly useful in lidar applications are described. According to one aspect of the present invention, an image sensor is designed to take advantage of the architecture of CMOS sensor with correlated double sampling, or CDS, to avoid the sensing speed being halved in order to cancel background light interference. It is commonly known that a photosensor is read twice (i.e., first and second readouts) in CDS for removing the inherent noises from the photosensor itself. Instead of subtracting a pixel's dark or reference output level from an actual light-induced signal, a background image is managed to be captured before the second readout of the sensor and subtracted from an actual image, where the actual image is defined to include an target. As a result, the readout speed of an image sensor is maintained while the background light interference is removed.

  • Patent number: 11068700
    Abstract: A method for enhancing an image for facial recognition comprises capturing an image of the face with a polarizer and correcting the polarized image for non-uniformity. Stokes Parameters S0, S1, S2 are obtained by weighted subtraction of the polarized image to form Stokes images. DoLP is computed from the Stokes images, and facial recognition algorithms are applied to the DoLP image. A system for enhancing images for facial recognition comprises a polarimeter configured to record polarized image data of a subject's face, a signal processing unit and logic configured to receive and store in memory the image data from the polarimeter, calculate Stokes parameters from the image data, and compute a DoLP image from the Stokes parameters.

  • Publication number: 20210214214
    Abstract: An optoelectronic module includes an optical filter and can have a relatively small overall height. The module includes a semiconductor die for the optical filter, where the die has a cavity in its underside. The cavity provides space to accommodate an optoelectronic device such as a light sensor or light emitter. Such an arrangement can reduce the overall height of the module, thereby facilitating its integration into a host device in which space is at a premium.

  • Publication number: 20210193275
    Abstract: An apparatus, system, and method for the measurement, aggregation and analysis of data collected using non-contact or minimally-contacting sensors provides quality of life parameters for individual subjects, particularly in the context of a controlled trial of interventions on human subjects (e.g., a clinical trial of a drug, or an evaluation of a consumer item such as a fragrance). In particular, non-contact or minimal-contact measurement of quality-of-life parameters such as sleep, stress, relaxation, drowsiness, temperature and emotional state of humans may be evaluated, together with automated sampling, storage, and transmission to a remote data analysis center. One component of the system is that the objective data is measured with as little disruption as possible to the normal behavior of the subject. The system can also support behavioral and pharmaceutical interventions aimed at improving quality of life.
