| 20090105679 | Hydrophilized Compositions Comprising Normally Hydrophobic Thermoplastic Polymers/Anionic Surfactants and Articles Shaped Therefrom - The invention concerns a method for preparing thermoplastics to obtain a hydrophilic behaviour of the surface of objects made from said thermoplastics. The invention also concerns the additives used to obtain said surface hydrophily, said additives being mixed and jointly melted with the thermoplastics (mass-additivation process). The melted mixtures of thermoplastics and additives are shaped by any conventional means (extrusion, injection film stretching) to obtain the desired objects. The invention further concerns the uses of said thermoplastic objects with hydrophilized surfaces. | 04-23-2009 |

| 20090161885 | Component for noise reducing earphone - An active noise reduction (ANR) component for provision in an earphone housing is disclosed. The device includes a driver and a sensing microphone, the driver and sensing microphone being housed in a component housing. The earphone housing has an outlet passageway from the ANR component to an auditory canal. The ANR component is adapted for use with a controller to provide active noise reduction to the auditory canal over a predetermined range of physical dimensions or acoustic parameters of the housing outlet passageway. The ANR component can thus be used with different housings which simplifies the design process for producing ANR earphone products. | 06-25-2009 |
