  • Patent number: 10656085
    Abstract: Systems for the monitoring of bacterial levels in samples, using spectral analysis of the light diffracted from a substrate with an ordered array of pores having diameters enabling the targets to enter them. The trapping pore array is cyclically illuminated by light of different wavelengths, and the light diffracted from the pore array is imaged by a 2-dimensional detector array, with one pixel, or a small group of pixels receiving light from each associated pore. The temporal sequence of frames provides a series of images, each from the reflection of a different wavelength. A time sequenced readout of the signal from the pixel or pixels associated with each pore region, provides a spectral plot of the reflected light from that pore region. Spectral analysis of the light intensity from this series of different wavelength enables the effective optical thickness (EOT) of each pore to be extracted.

  • Patent number: 10620447
    Abstract: A coherent beam moves across a stationary line generator, allowing the speckle pattern projected through the diffuser onto the surface—for example using a MEMS mirror, or another arrangement that is free of a moving mass, such as solid state beam deflector (e.g. an AOM). Where an image sensor is employed, such as a DS, the beam is moved at a speed of at least ½ cycle per image frame so that the full length of the line within the imaged scene is captured by the image sensor. The distance traversed on the diffuser provides sufficient uncorrelated speckle patterns within an exposure time to average to a smooth line. The MEMS mirror can be arranged to oscillate in two substantially orthogonal degrees of freedom so that the line is generated along a first direction and the line moves along the working surface in a second direction.

  • Patent number: 10168207
    Abstract: In an approach to monitoring sunscreen effectiveness, a computer receives input from a user. The computer receives data corresponding to ultraviolet radiation exposure from a first ultraviolet radiation sensor and a second ultraviolet radiation sensor. The computer determines an amount of ultraviolet radiation received by the first ultraviolet radiation sensor and the second ultraviolet radiation sensor. The computer determines whether the amount of ultraviolet radiation received by the first ultraviolet radiation sensor is similar to the amount of ultraviolet radiation received by the second ultraviolet radiation sensor. The computer determines whether the amount of ultraviolet radiation received by the first ultraviolet radiation sensor is below an alert threshold. In response to determining the amount of ultraviolet radiation received by the first ultraviolet radiation sensor is not below an alert threshold, the computer transmits an alert message to the user.
