Smartphone-based methods and systems
First Claim
1. In a lighting fixture comprising:
- a connection to a power line;
at least one LED light emitter to illuminate an environment; and
a control unit to receive a first signal and vary intensity of light output by the light emitter in response to the first signal;
an improvement wherein;
the first signal is a digital control signal received over the power line, and the fixture also includes;
a content sensor for capturing audio or image information;
a data processing unit coupled to the sensor to generate content identification information based on the captured audio or image information, said content identification information being different than the captured information; and
a modulator to encode light output by the light emitter with a second signal, where the second signal is based on the content identification information;
wherein the fixture is adapted to vary light output by the emitter in accordance with both the first and second signals.

Abstract
Arrangements involving portable devices (e.g., smartphones and tablet computers) are disclosed. One arrangement enables a content creator to select software with which that creator'"'"'s content should be rendered—assuring continuity between artistic intention and delivery. Another utilizes a device camera to identify nearby subjects, and take actions based thereon. Others rely on near field chip (RFID) identification of objects, or on identification of audio streams (e.g., music, voice). Some technologies concern improvements to the user interfaces associated with such devices. Others involve use of these devices in connection with shopping, text entry, sign language interpretation, and vision-based discovery. Still other improvements are architectural in nature, e.g., relating to evidence-based state machines, and blackboard systems. Yet other technologies concern use of linked data in portable devices—some of which exploit GPU capabilities. Still other technologies concern computational photography. A great variety of other features and arrangements are also detailed.
