David Merrill - Somerville MA, US

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

G06F 17/00

US Classification:

700 94

Abstract:

A system for interactive audio recording and manipulation may include a controller having at least one two-axis analog control and plurality of control buttons. The controller may be coupled to a computing device including a processor, a memory, and an audio interface including at least one audio input port to accept an input audio signal and at least one audio output port to provide an output audio signal. The system may perform actions in response to inputs from the controller. The actions may include recording the audio input signal as a recorded track, playing the recorded track to provide an audio output signal, scrubbing the recorded track in response to activation of the two-axis analog control along a first axis, and pitch-shifting one of the input audio signal and the output audio signal in response to activation of the two axis analog control along a second axis.

Abstract:

An assembly for creating a fire display from a liquid fuel comprises a fuel receiving reservoir connected to a burner by a conduit, the conduit providing a flow channel for a liquid fuel from the reservoir to the burner. When a container of liquid fuel is placed in a bottle receiving tray the fuel is dispensed into the reservoir and in turn flows into the burner. Flammable vapors over the liquid fuel in the burner can then be ignited. The arrangement provides a continuous feed of fuel to the burner and allows safe replacement of the fuel container and replenishment of the fuel in the burner while the flame is present.
