An electronic device includes a display including an emission unit, a light sensor configured to generate a signal indicative of ambient light level, a memory in which filtering instructions and emission control instructions are stored, and a processor configured to implement the filtering instructions to generate at least one filtered representation of the ambient light level in accordance with the signal. The processor is further configured to implement the emission control instructions to determine whether the ambient light level is increasing or decreasing, and to generate a control signal that, based on the at least one filtered representation, increases a brightness level of the emission unit at a first rate if the ambient light level is increasing and that decreases the brightness level at a second rate if the ambient light level is decreasing. The first rate is greater than the second rate.

Emission unit brightness adjustment

Embodiments related to network video messaging are disclosed. One disclosed embodiment provides a method that comprises receiving a video message from a client application of a source client; associating a navigation link with the video message; transmitting a notification message to the recipient client including the navigation link; receiving a retrieval request from the recipient client to access the video content via the navigation link; and transmitting the video content to the recipient client responsive to receiving the retrieval request by providing a persistent download of the video content from the storage server if the download condition indicates that a persistent download of the video content is permissible; and providing a transient download of the video content to the recipient client while prohibiting a persistent download of the video content if the download condition indicates that a persistent download of the video content is not permissible.

Network video messaging

An electronic device can be locked and secured by activating a hardware locking mechanism on the device. The locking mechanism is controlled by a locking policy that is defined and implemented from the client side. If the locking mechanism is activated, then the device operates in a limited mode of operation instead of in a normal mode of operation. The locking mechanism can be deactivated, placing the device into the normal mode of operation, when a specified condition is satisfied.

Time managed read and write access to a data storage device. As a part of time managed read and write access to a data storage device, a request for read and/or write access to the data storage device is accessed and it is determined whether the request for read and/or write access to the data storage device is to be granted. Based on the determination, read and/or write access to the data storage device is either allowed or blocked. If read and/or write access is allowed, read and/or write access is terminated after passage of a predetermined period of time.

The claimed method and system monitors computer system timer(s) relative to other timers to detect discrepancies and/or may capture an offset to provide a method of more accurately determining a current time. The invention may also provide a method to detect power source tampering using a last known good time and may provide a means to securely initialize system time using an encrypted time stamp.

Method to securely initialize, protect and recover system date/time

Techniques to provide a secure execution environment are described. In an implementation, a method includes initiating a hardware interrupt by an embedded controller of a computing device. In response to the interrupt, a module is executed that is stored in a basic input/output system (BIOS). The module, when executed, determines whether constrain functionality of the computing device based on a balance.

BIOS based secure execution environment
