Abstract: An aquarium system includes a tank, a motion sensor, and a light source. The motion sensor is adapted to sense motion within a predetermined distance from the tank. The light source has a controllable intensity projecting light into the tank. The intensity varies responsive to motion sensed by the motion sensor. When the motion sensor senses movement, the light is on at 100% intensity. After some period of no-motion, such as about 60 seconds, the lighting slowly dims to around 20% of full brightness. When it senses movement again, the lighting slowly ramps up to 100% intensity.

Abstract: A system is disclosed for using an audio time and level difference renderer (TLDR) to generate spatialized audio content for multiple channels from an audio signal received at a single channel. The system selects an audio TLDR from a set of audio TLDRs based on received input parameters.

The system applies the configured audio TLDR to an audio signal received at the single channel to generate spatialized multiple channel audio content for each channel of the multiple audio channel and presents the generated spatialized audio content at multiple channels to a user via a headset.

Abstract: Techniques are described for generating spatialized audio content based on head orientation information and torso orientation information obtained from a drift compensation system. The drift compensation system compensates for drift in measurements performed by an inertial measurement unit (IMU), based on biological constraints pertaining to a user. The head orientation information is applied to a first set of filters to generate intermediate audio content. In turn, the torso orientation information and the intermediate audio content are applied to a second set of filters to generate the spatialized audio content. The first set of filters includes one or more audio filters that receive an input audio signal corresponding to a left channel. The second set of filters includes one or more audio filters that receive an input audio signal corresponding to a right channel. The spatialized audio content includes separate output signals for the left channel and the right channel.
