  • Patent number: 10718509
    Abstract: A light fixture and directional assistive listening device includes a portable lamp fixture, a parabolic sound membrane, and a light and acoustic transducer assembly. The portable lamp fixture includes a stand, a light socket, and a primary power cord. The primary power cord is electrically connected to the light socket through the stand. The parabolic sound membrane is concentrically attached to the light socket. The light and acoustic transducer assembly is electrically connected to the light socket and concentrically positioned within the parabolic sound membrane. When the light and acoustic transducer assembly is communicably coupled with an external audio device, the light and acoustic transducer is able to output greater clarity of speech and directionality of sound due to the configuration and positioning of the light and acoustic transducer assembly and the parabolic sound membrane.

  • Patent number: 5665186
    Abstract: An absorbent article includes a moisture barrier formed of a formable, liquid impermeable material. The moisture barrier defines a basin having a width dimension, a length dimension greater than the width dimension, and a volume. The basin includes a floor having corrugations formed therein parallel to the width dimension. The absorbent article also includes an absorbent assembly disposed within the basin and a liner formed of a liquid permeable material bonded to the moisture barrier and sandwiching the absorbent assembly therebetween. The corrugations permit the absorbent article to bend inwardly, for example to conform to the shape of the wearer, without bunching the moisture barrier along the portions facing the wearer and without substantially stretching or deforming the floor of the moisture barrier.
