Abstract: A device includes a first camera and a second camera respectively supported by a first and a second assemblies coupled via a hinge. The first and the second cameras are configured to respectively capture a first image and a second image that include a common reference object. A controller is coupled to the first and the second cameras, and configured to change an operating mode of the device in response to a comparison between the first and the second images. Additional cameras may be used in further embodiments and may be mounted onto the front and back surfaces of the first and the second assemblies.

Abstract: A shutter system includes an electronic device having a camera with a lens. A shutter is supported by the electronic device to block light transmission through the lens in a first state and permit light transmission in a second state. The shutter includes a shutter body containing electrically charged light blocking particles in suspension, a first pair of electrodes positioned to move the electrically charged light blocking particles to achieve the first state in response to a first voltage being applied to the first pair of electrodes, and a second pair of electrodes positioned to move the electrically charged light blocking particles to achieve the second state in response to a second voltage being applied to the second pair of electrodes.

Abstract: Access to a system is permitted by first polling a low-power device/connection on a user device for a low-power multifactor authentication (MFA), and; refraining from polling a high-power device/connection on the user device for a high-power MFA. An indication is received from a user that the user would like to access the system. The low-power MFA is identified via the polling of the low-power device/connection, and the user is authenticated via the low-power MFA. After authenticating the user via the low-power MFA, the high-power device/connection is woken and polled for the high-power MFA. The high-power MFA is identified via the polling of the high-power device/connection, and the user is authenticated via the high-power MFA. Access to the system is permitted when the user has been authenticated using the low-power MFA and the high-power MFA.
