Abstract: A technology is described for a repeater comprising a modem configured to function as a time division duplex (TDD) uplink/downlink modem configured as a scanning sync detection module (SDM) configured to determine an UL/DL configuration information and scan channels for monitoring information. The modem can be configured to: identify one or more frequency ranges associated with a plurality of cellular carriers; scan the one or more frequency ranges; identify monitoring information that includes cellular carrier specific information for the one or more frequency ranges associated with the plurality of cellular carriers; and provide the monitoring information to the repeater for communication to the remote server.

Abstract: Computer display privacy and security for computer systems. In one aspect, the invention provides a computer-controlled system for regulating the interaction between a computer and a user of the computer based on the environment of the computer and the user. For example, the computer-controlled system provided by the invention comprises an input-output device including an image sensor configured to collect facial recognition data proximate to the computer. The system also includes a user security parameter database encoding security parameters associated with the user; the database is also configured to communicate with the security processor. The security processor is configured to receive the facial recognition data and the security parameters associated with the user, and is further configured to at least partially control the operation of the data input device and the data output device in response to the facial recognition data and the security parameters associated with the user.
