The mid-range loudspeaker is arranged between the first tweeter and the second tweeter. The mid-range loudspeaker is a non-directional loudspeaker that radiates sound towards a driver’s seat and towards a passenger seat in equal parts. The first tweeter is a directional loudspeaker that radiates sound primarily towards the passenger seat, and the second tweeter is a directional loudspeaker that radiates sound primarily towards the driver’s seat.

Abstract: An apparatus for re-distributing acoustic energy. The apparatus comprises a first concave surface defined as a surface of revolution of a line or curve. This curve of revolution is rotated beyond 230 degrees and thus defines a rather small opening, which has advantages in the frequency response output. Additionally or alternatively, edges of the concave surface may be rounded to provide advantageous effects in the sound output.

Abstract: This device is a balance board used for core exercise, balance training, and training for rotational motion applicable to various board sports. The invention consists of a board or deck upon which the user stands having the shape and contours of a traditional skateboard deck. On the underside of the board are three half spherical fulcrum points fixed at specific locations. The primary fulcrum point is the largest and is located in the center of the board. The additional two fulcrum points are smaller and are located one each at the nose and tail of the board. This orientation allows the user to spin freely on the board on a horizontal axis. Rotational motion is possible on any of the three fulcrum points depending on the user's ability.

Abstract: A method and system for providing information to a user positioned in a room with two independent listening areas where, in one area, an audio signal is output compensating for the sound from the other area, and where a position between the two areas is indicated to a user. When the user moves about, the position and size of one listening area may change, and the user may be made aware of any conflict with the other listening area. The areas may be defined by boundaries where a compensation quality is at a threshold quality.

Abstract: A universal bracket allowing secure attachment of accessories to paddleboards or similar watercraft. Said bracket consists of two identical assemblies of three components. The first is a rectangular plastic tube that rests on the top surface of the paddleboard. Said tube is open at each end and acts as a receiving tube for two smaller rectangular plastic tubes. The smaller tubes each having a molded hook on one end that attaches to the outer edges of the paddleboard. The width of the assembly is adjustable to accommodate varying paddleboard sizes. The adjustable nature is such that the outer tubes slide freely into the center tube and are locked in place by a removable pin. The pin locking system allows for customization and a variety of settings. The center receiving tube contains a mechanism for securing accessories that expand the capabilities of a paddleboard.

Abstract: The invention combines systems and methods for heat containment and cold air isolation for managing airflow and temperature in data centers. The data center contains at least two rows of cabinets containing heat-generating equipment and arranged to form a cold aisle and a hot aisle. The data center system includes panels or doors at both ends of the cold aisle and an optional cover over the cold aisle to inhibit cooled air supplied by an air conditioning system from exiting the cold aisle and inhibit air warmed by the heat-generating components from entering the cold aisle. A chimney coupled to the top, rear, or top and rear of the cabinets is configured to exhaust the warmed air into a region above the rows of cabinets. The chimneys may be ducted to a plenum or suspended ceiling or to the intake of the air conditioning system. Baffles and/or fans may be included in the chimneys, ducts, and/or plenums to control the air pressure.
