An active road noise control system and method for a vehicle includes generating a microphone sense signal representative of road noise occurring in or at a wheel well of the vehicle, and iteratively and adaptively processing the microphone sense signal to provide a noise reducing signal. The system and method further include generating from the noise reducing signal with a headrest loudspeaker arrangement disposed in a headrest in an interior of the vehicle, noise reducing sound at a listening position in the interior of the vehicle.

A system such as a vehicle, building, vessel, aircraft, or electronic device system may have a layer of material with invisible laser-drilled openings. The layer of material may include an outer layer of fabric overlapping an inner layer such as an inner foam layer. Laser-drilled openings may include outer openings in the fabric layer and inner openings in the foam layer. Each of the inner openings may be overlapped by multiple outer openings. The exposed surface of the fabric layer may have strands of material of different appearances and/or may otherwise be configured to help visually hide the laser-drilled openings. Laser-drilled openings may also have small sizes to help make the laser-drilled openings invisible. Laser-drilled openings may overlap components such as audio components, heating and cooling components, and/or light-emitting components.

A ventilation system for a seat cushion comprises a reticulated ventilation manifold disposed in the seat cushion. The ventilation manifold has an inlet disposed adjacent a first side of the cushion and a plurality of manifold ducts extending from the inlet to terminate in outlets disposed at or near openings in a second side of the cushion. A fan motor is attached adjacent the first side of the cushion and has a fan outlet in fluid communication with the inlet of the ventilation manifold. The fan motor operates to apply a positive or a negative pressure, via the fan outlet to the ventilation manifold to supply air through the ventilation manifold and the cushion.

A pillow includes a support body. A shape-adapting frame is within the support body. The shape-adapting frame is configured to be moved into and maintained in a desired position. At least one sensor is configured to detect at least one condition. The sensor(s) may be in communication with a monitoring control unit of a monitoring system.

A ventilated airline seating component including a porous air pad disposed in an interior volume of a housing and configured to collect air to be conditioned and ultimately forced out through the seating component to heat or cool a passenger to enhance comfort. The housing can serve as or be incorporated into a seating component such as an arm rest, leg rest or head rest, among other seating components within a passenger seating environment.
