  • Patent number: 9959422
    Abstract: Techniques and technologies for providing limited-access functionality accessible at a “login screen” (or “lock screen”) of a device are described. In at least some embodiments, a system includes a user interface operatively coupled to a processing component; and one or more instructions stored on a memory that, when executed by the processing component, are configured to: (a) generate a login portion displayed on the user interface, the login portion configured to receive at least one user access credential to determine whether to provide access to one or more authorized-access functionalities; and (b) generate a limited-access functionality access portion displayed on the user interface concurrently with the login portion, the limited-access functionality access portion configured to provide access to at least one limited-access functionality without requiring receipt of the at least one user access credential.

  • Patent number: 8860793
    Abstract: The present Invention relates to a camera system suitable for use in minimally invasive surgery (MIS), among other applications. In at least one embodiment, the camera system includes an autonomous miniature camera, a light source assembly providing features such as steerable illumination and a variable radiation angle, and a control and processing unit for processing images acquired by the camera Io generate improved images having reduced blurring using a deblurring algorithm.
