Processes and devices for equalizing an audio system that is adapted to use a loudspeaker to transduce test audio signals into test sounds. The processes and devices can involve the use of infrared signals to convey information in one or both directions between the audio system and a portable computer device that captures test sounds, calculates audio parameters that can be used in the equalization process, and transmits these audio parameters back to the audio system for its use in equalizing audio signals that are played by the audio system.

An optoelectronic module includes a transceiver operable to transmit data optically. The transceiver includes a light emitter to emit light from the module, and a light detector to detect light entering the module. The light detector is disposed at a rotationally symmetric position with respect to a central axis of the module. Such modules can help facilitate the exchange of data optically between two devices.

The present invention relates to an NADP(H) nanosensor comprising i) a nucleic acid sequence to which a regulator is capable of binding, wherein the oxidation state of the regulator depends on the NADP(H) availability; ii) a promoter sequence following the nucleic acid sequence i), to which an RNA polymerase is capable of binding, wherein the affinity of the RNA polymerase for the promoter sequence is influenced by the oxidation state of the regulator; iii) a nucleic acid sequence which is under the control of the promoter sequence ii) and which codes for an autofluorescent protein.

The present invention also relates to a cell, a method for isolating genes which code for NADP(H)-dependent enzymes, and the use of an NADP(H) nanosensor.

Systems and methods for optical narrowcasting are provided for transmitting various types of content. Optical narrowcasting content indicative of the presence of additional information along with identifying information may be transmitted. The additional information (which may include meaningful amounts of advertising information, media, or any other content) may also be transmitted as optical narrowcasting content. Elements of an optical narrowcasting system may include optical transmitters and optical receivers which can be configured to be operative at distances ranging from, e.g., 400 meters to 1200 meters. Additionally, the elements can be implemented on a miniaturized scale in conjunction with small, user devices such as smartphones. Moreover, optically narrowcast content may be filtered using at least identification data extracted from optical beacons received from optical transmitters such that only optically narrowcast content of interest is presented on a display and/or stored in a persistent storage.
