  • Patent number: 11571115
    Abstract: The present invention describes an electromagnetically positioning system, which can measure a position and orientation of a remote object in an isolated targeted examination area with time. Specifically, the remote object is a remote miniaturized examination device. During the location process, both the electromagnetically positioning system and the remote miniaturized examination device can have expected or unexpected, controlled and can-not-be-controlled movement. By implementing the electromagnetically positioning system, disclosed herein, position and orientation information of the remote miniaturized examination device can be linked with time, any information collected by the remote miniaturized examination device, for example, the photo images collected, can be associated kinetically with time and positioning information of the examination device, when the remote miniaturized examination device travels inside an isolated target examination area.

  • Patent number: 11497414
    Abstract: A pump-less breath analysis device regulates the flow of breath past a nanoparticle sensor (or other semiconductor sensor) by dynamically adjusting the state or position of a valve as the user exhales into the device. The valve controls the flow of incoming breath between two flow paths: a venting path through which breath exits the device without passing by the nanoparticle sensor, and a sensing path that includes the nanoparticle sensor. In some embodiments, the valve is controlled by a processor that monitors pressure produced by the user's exhalation force. Based on these real-time pressure measurements, the processor adjusts the valve to maintain the pressure, and thus the flow rate, in the sensing path within a desired range. The processor may also use the pressure measurements to determine whether the characteristics of the user's exhalation are sufficient to generate a valid measurement.

    Abstract: The present disclosure describes systems and methods that enable eye-tracking by steering a light signal in a high-density Lissajous pattern over a region of an eye and detecting light reflected from the eye using a non-imaging photodetector configuration. The light signal is scanned by driving each axis of a two-axis MEMS scanner with a periodic signal having a frequency that is based on the resonant frequency of that axis. By choosing periodic signals having frequencies that give rise to precession of the Lissajous pattern at a high rate, a high-density scan pattern is quickly generated, thereby enabling eye tracking with high spatial resolution and low latency.

  • Patent number: 11435233
    Abstract: In part, the invention relates to systems and methods of calibrating a plurality of frames generated with respect to a blood vessel as a result of a pullback of an intravascular imaging probe being pullback through the vessel. A calibration feature disposed in the frames that changes between a subset of the frames can be used to perform calibration. Calibration can be performed post-pullback. Various filters and image processing techniques can be used to identify one or more feature in the frames including, without limitation, a calibration feature, a guidewire, a side branch, a stent strut, a lumen of the blood vessel, and other features. The feature can be displayed using a graphic user interface.
