Abstract: A vision screening device for administering vision screening tests to a patient, including an oversampling sensor allowing operation of the device at various distances from a patient, is described herein. The vision screening device may include associated methods and systems configured to capture a series of oversampled images, detect the patient's face and eyes in the images, track the eyes, and output a stabilized eye image for performing the vision screening tests. The device may also be configured to determine measurements related to the positions of the eyes in the eye image, and determine, based on the measurements, if the eye image satisfies criteria for use in the vision screening tests being performed. Methods associated with the device may be configured to provide guidance to an operator of the device to adjust either the device or the patient's position so that an eye image meeting the criteria can be generated.

Abstract: Software of devices, such as medical devices or other constrained devices configured to implement specific functions, can use content files to determine text strings or other content values to present in association with user interface elements. Devices can receive relevant content files, such as new versions of previously-stored content files or new content files containing text in different languages, from a remote content file repository. The software of the devices can accordingly update content values presented in user interfaces based on newly received content files, without the software being re-coded, the software being restarted, or the devices rebooting.
