  • Publication number: 20200237214
    Abstract: Introduced here are retinal cameras having optical stops whose size and/or position can be modified to increase the size of the space in which an eye can move while being imaged. In some embodiments, an optical stop is mechanically moved to recover retinal image quality as the subject shifts their eye. In some embodiments, an optical stop is digitally created using a pixelated liquid crystal display (LCD) layer having multiple pixels that are individually controllably. In some embodiments, multiple non-pixelated LCD layers are connected to one another to form a variable transmission stack, and each LCD layer within the variable transmission stack may be offset from the other LCD layers. In such embodiments, the optical stop can be moved by changing which LCD layer is active at a given point in time.

  • Publication number: 20200100675
    Abstract: Methods, sensors, and systems that prevent or reduce data loss when more than one external sensor transceiver is used with a sensor. A sensor may receive a transceiver identification (ID) of an external transceiver conveyed from the external transceiver and determine whether the received transceiver ID is a new transceiver ID. If sensor determines the received transceiver ID to be a new transceiver ID, the sensor may store the received transceiver ID in a nonvolatile storage medium of the sensor and convey, using the sensor, measurement information stored in the nonvolatile storage medium to the external transceiver.
