Abstract: An earpiece for real-time audio processing of ambient sound includes an ear bud that provides passive noise attenuation to the earpiece such that exterior ambient sound is substantially reduced within an ear of a wearer, an exterior microphone that receives ambient sound and converts the received ambient sound into analog electrical signals, and an analog-to-digital converter that converts the analog electrical signals into digital signals representative of the ambient sounds. The earpiece further includes a digital signal processor that performs a transformation operation on the digital signals according to instructions received from a mobile device, the transformation operation transforms the digital signals into modified digital signals, a digital-to-analog converter that converts the modified digital signals into modified analog electrical signals, and a speaker that outputs the modified analog electrical signals as audio waves.

Abstract: According to one aspect of the invention, a method for directing the use of a sprayer includes the step of directing a user to affix a sprayer to a neck of a water bottle (114) via an attachment mechanism (112). The method further includes the step of directing the user to adjust the attachment mechanism (112) to change the internal geometry thereof and attach the sprayer to the neck of the bottle.

Abstract: Ambient sound is converted into digital signals. A processor performs active noise cancellation and/or a transformation operation that is distinct from the active noise cancellation on the digital signals. The active noise cancellation and the transformation operation transform the digital signals into modified digital signals. The modified digital signals are converted into modified analog signals. The modified analog signals are outputted as audio waves. An interior microphone is configured to output an output signal to the processor in response to receiving the modified analog signals. In response to receiving the output signal from the interior microphone, the processor is configured to determine whether the modified digital signals produce desired audio waves.

Abstract: There is disclosed a passive acoustical filter including two or more filter elements coupled between an ambient and a listener's ear, each of the filter elements selected from the group consisting of a low pass filter element, a high pass filter element, a band reject filter element, and a band pass filter element.

Abstract: A dispensing system includes a manifold adapted to be fluidly coupled to a valve stem of a container. The manifold includes first and second members extending outwardly from the manifold. The dispensing system also includes a shroud having first and second shroud portions on opposing sides of the shroud. The dispensing system further includes at least one enclosed track. The enclosed track receives and permits sliding of at least one of the first and second members.

Abstract: There is disclosed a passive acoustical filter including a first filter element coupled between an ambient and an ear of a listener, at least a portion of the first filter element filled with a material in which a speed of sound is lower than a speed of sound in air.
