A system and method for optical communication between multiple UUVs, more specifically, for leader-follower formations between UUVs. The system focuses on the characterization and modeling of a 1-dimensional and/or 3-dimensional light field produced from a light source mounted on a Leader UUV, which is detected by one or more follower UUVs. Communication algorithms are used to monitor the UUV's motion and orientation utilizing simulators, look up tables, and the like. A variety of detectors arrays can be used in a variety of wavelengths depending on the desired application.

A system for moving a barrier includes a motor with an integrated encoder operative to generate pulses as a function of rotation of the rotatable shaft of the motor. A preferred form of encoder is a rotary optical encoder to generate optical pulses as a function of rotational movement of the rotatable shaft. Both a microcontroller to determine door status and a controller to control door movement receive the pulses and separately execute methods in response thereto.

According to one configuration, a remote controller device wirelessly controls a remote media system. The remote controller device includes multiple selectable control buttons, multiple optical sources, and controller hardware. Each optical source individually back-illuminates a respective selectable control button of the multiple selectable buttons. The controller hardware selectively activates different groupings of the multiple optical sources depending upon a current operational mode of the remote media system. For example, a respective user of the remote controller device selects a particular button of the remote controller device corresponding to the first operational mode. The remote controller device, in turn, transmits a wireless signal to the remote media system to control the remote media system to the first operational mode. Rather than illuminating all buttons, the remote controller device then back-illuminates only a relevant group of multiple selectable control buttons applicable to the first operational mode.

Provided is an information-providing system whereby a variety of information can be provided using a sound to a portable terminal device used by a user. The information-providing system includes a sound output device outputting, as a sound wave, identifying information modulated into a sound signal, an identifying-information resolution server, connected to an information-communication network, for identifying, based on the identifying information, address information for accessing a content server connected to an information-communication network; and a portable terminal device including a sound receiving section for receiving the sound wave outputted by the sound-emitting device, a demodulating section for demodulating the identifying information from the received sound wave, a resolution section for sending the demodulated identifying information to the identifying-information resolution server and acquiring the address information, and an accessing section for accessing the content server using the acquired address information.
