Patent number: 11858723Abstract: A modular portable storage container system includes a storage container having first and second sections. The first section defines a first partial volume of storage space and the second section defines a second partial volume of storage space. The system further includes a lock mechanism with a lock arm, lock handle, and pivot shaft defining an axis of rotation. The lock arm and handle are fixed for common rotation with the pivot shaft. The arm extends radially outward from the pivot shaft to a roller assembly. A lock track is disposed within the second section and extends from a fluted open portion to a closed end, with a continuous track portion disposed therebetween. The first and second sections are movable between at least closed and open positions. In the closed position, the roller assembly engages with the lock track and retains the first section in contact with the second portion.Type: GrantFiled: August 24, 2021Date of Patent: January 2, 2024Assignee: QT-System LLCInventors: Stuart Fletcher, Scott Owen

Publication number: 20230067327Abstract: A modular portable storage container system includes a first container section and a second container section, each of the first and second container sections having a structural frame. A blocking frame is sized and shaped to fit within a vehicle cargo compartment. A latch mechanism selectively retains the structural frame of each of the first and second container sections in contact with the blocking frame. A position sensor is in communication with a position indicator. The position sensor detects a position of the first and second container sections relative to the blocking frame. The position indicator indicates a position of the first and second container sections relative to the blocking frame. A plurality of casters affixed to a bottom surface of the first and second container sections allows the first and second container sections to roll over the floor.Type: ApplicationFiled: October 19, 2022Publication date: March 2, 2023Inventors: Stuart Fletcher, Scott Owen

Patent number: 8774424Abstract: Apparatus for reproducing sound including at least three loudspeakers (5, 6, 7) mounted in a substantially sealed enclosure. The three loudspeakers may be mounted to a wall of the enclosure so that they are all directed away from, and evenly spaced around, a common point. Two speakers may be driven with the respective out of phase signals comprising the difference between two stereo channels and another speaker with the sum of those channels.Type: GrantFiled: November 18, 2009Date of Patent: July 8, 2014Assignee: Airsound LLPInventor: Stuart Fletcher

Patent number: 8767984Abstract: Apparatus for reproduction of stereo sound from a two channel signal, having one or more first transducers (3a, 3b) for reproducing a signal comprising one of or the sum of the two channels, and one or more second transducers (5) for reproducing a signal comprising the difference between the two channels. The apparatus is arranged such that the signal generated by the one or more first transducers (3a, 3b) is transmitted from an output plane in a direction substantially orthogonal to the output plane. The apparatus also has a duct (6) associated with the one or more second transducers (5) and is arranged to conduct the signal generated by the one or more second transducers (5) such that it is transmitted along a direction substantially parallel to the output plane from a point spaced from the plane in the direction in which the signal generated by the one or more first transducers (3a, 3b) is transmitted.Type: GrantFiled: December 8, 2008Date of Patent: July 1, 2014Assignee: Airsound LLPInventor: Edward Stuart Fletcher

Patent number: 8553914Abstract: Apparatus for reproducing stereo sound having a housing (1, 25) defining an at least partially enclosed space. A first transducer (7) or pair of transducers (28, 29) is provided and arranged to reproduce one, both or the sum of two audio signals. A pair of transducers (10, 32) is also provided and arranged to reproduce a signal comprising the difference of the two audio signals. As the transducers communicate with the at least partially enclosed space, and the transducers arranged to reproduce the difference between the two audio signals are each arranged to direct their output primarily in a direction generally at right angles to the direction in which the first transducer or pair of transducers primarily direct their output. The apparatus may be arranged to be placed on or adjacent a generally flat surface, and the transducers arranged to reproduce the difference of the two audio signals may be arranged to direct their output towards the flat surface.Type: GrantFiled: August 21, 2007Date of Patent: October 8, 2013Assignee: Airsound LLPInventor: Edward Stuart Fletcher

Patent number: 8391516Abstract: A method of using an audio device (2) for improving a user's (1) listening experience. The audio device has a transducer (12) for producing output sound and the method comprises the steps of driving the transducer to produce an output sound and placing the audio device against the body of the user so that the user experiences a physical response to the sound while simultaneously listening to the audio device. The audio device may be arranged to produce a resonance in a part of the user's body. Preferably the audio device is positioned on the user's chest to produce a resonance in the chest cavity of the user's body. The audio device may comprise a sum and difference speaker system.Type: GrantFiled: August 14, 2008Date of Patent: March 5, 2013Assignee: Airsound LLPInventor: Edward Stuart Fletcher

Publication number: 20090067635Abstract: An apparatus and method for reproducing stereo sound. A transducer (14) is provided for reproducing two audio signals which are substantially out of phase with each other. Means, such as duct (11), are associated with the transducer to conduct at least one of the audio signals to a location such that the two substantially out of phase signals are transmitted from respective spaced apart locations. The duct (11) may lead to ports (4). These may be elongate and arranged to transmit sound across a flat surface. A second transducer (8) may be provided for transmitting a second audio signal. A conventional two channel stereo audio signal may be reproduced by the sum and difference system.Type: ApplicationFiled: August 21, 2008Publication date: March 12, 2009Applicant: Airsound LLPInventor: EDWARD STUART FLETCHER
