Abstract: A light source package for selectively interrupting power to a light source is provided. An optical element is positioned to reflect a reflected portion of the light from the light source. The reflected portion impinges upon a base that includes a roof panel with a light source side and a sensor side that is opposite to the light source side. The light source side of the roof panel receives the reflected portion of the light and transmits a transmitted portion of the light through the roof panel. The sensor side of the roof panel includes a recess in which a sensing component is located. The sensing component receives the transmitted portion of the light and is configured to interrupt power to the light source when the transmitted portion of the light is below a threshold.

Abstract: Content signaturing is provided by a display receiver device comprising one or more source inputs, where each source input is configured to receive a content signal from a corresponding content source. The display receiver device further comprises a content identification module to send sample information derived from each received content signal to a signature processor and to receive from the signature processor content information for each corresponding content source, the content information for a particular content source indicating a content item embodied by the content signal received from that particular content source. The display receiver device further comprises an association module to associate the content item corresponding to the particular content source with one or more associated content items not corresponding to the particular content source.

The display device further comprises a content identification module to send sample information derived from each received content signal to a signature processor and to receive from the signature processor content information for each corresponding content source. The display device further comprises a user interface module to produce a unified user interface including a menu option for each content source, where each menu option includes content information identified via the content identification module for the corresponding content source. The display device further comprises a display to visually present the unified user interface.
