    Abstract: Streaming content using a data streaming device having limited power is described. A data streaming device receives streaming content from a network and provides the streaming content for display on a content display device. Data streaming device includes power supplies that receive power from the content display device. The power supplies use the power to operate components of data streaming device that process the streaming content. A measuring module measures the power provided to the data streaming device. When the power is insufficient, a controller generates an indication that there is insufficient power to operate the components of the data streaming device. The controller may also modify functionality of the components to operate using available power or disable a component of the data streaming device.

    Abstract: Disclosed herein are system, method, and computer program product embodiments for a USB-based media device upgrading system. An embodiment operates by receiving a fetch command from a first instance of an application executing locally on a host device physically connected to media device. The fetch command is provided to a media device executing a second instance of the application. At the host device, metadata corresponding to the file that was retrieved by the media device is received. A rendering command is determined from the first instance of the application corresponding to displaying the interface including the fetched file as indicated by the metadata. The rendering command is provided to the media device that is configured to display the interface of the application responsive to executing the rendering command.

    Abstract: Disclosed herein are system, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for generating a long exposure composite image (LECI) frame, wherein the LECI frame provides a summary of activity in a monitored environment over a duration of time. An embodiment captures, using an image-capturing device, a sequence of image frames over the duration of time using an optical sensor of the image-capturing device. The embodiment then generates the LECI frame, using an embedded low-power processor coupled to the optical sensor and dedicated to generating LECI frames, by combining the sequence of image frames. The embodiment then transmits the LECI frame to a network device using a transceiver coupled to the low-power processor.

    Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for detecting downstream devices connected to an electrical load controlling device. An example embodiment operates by detecting an association signal from a downstream smart device responsive to a downstream smart device detection signal. The example embodiment further operates by determining whether the downstream smart device is coupled to an electrical terminal of an electrical switching device and configured to receive electricity in response to an actuation of the electrical switching device. If so, the example embodiment further operates by generating a control signal configured to instruct the electrical switching device to prevent a deactuation of the electrical switching device and transmitting the control signal to the electrical switching device.
