Abstract: A cast film inducing a bimodal ethylene-based polymer having a high density fraction (HDF) from 3.0% to 10.0%, an I10/I2 ratio from 5.5 to 7.0, a short chain branching distribution (SCBD) less than or equal to 10° C., a density from 0.910 g/cc to 0.920 g/cc, and a melt index (I2) from 1.0 g/10 mins to 8.0 g/10 mins.

Abstract: A toothbrush provides a head with bristles, a neck and a handle. An eccentrically rotational weight is engaged for rotation with a motor. The motor and weight are disposed within the handle. The handle, neck and head each have a different intensity of vibration. The toothbrush houses an electrical circuit, which includes a processor and at least two LEDs (light emitting diodes) at least one of which illuminates the neck and optionally also the head and the ends of the bristles attached to the head. At least two of the LEDs in the circuit are capable of emitting different colored light with respect to each other. The at least two LEDs are switched on for a predetermined time in a predetermined sequence under the control of the processor.

Abstract: An electronic device as provided here includes a primary housing, an acoustic transducer, a lower layer of acoustic mesh material, and an upper layer of acoustic mesh material. An interior volume is defined within the primary housing. The primary housing includes an interior mounting surface, an exterior mounting surface, and an acoustic port. The transducer is located within the interior volume, and the lower layer of mesh material is coupled between the interior mounting surface and the transducer to cover a lower opening of the acoustic port. The upper layer of mesh material covers an upper opening of the acoustic port. Each layer of mesh material provides an amount of acoustic transparency and an amount of visual obscurity such that the transducer is effectively hidden from view without adversely impacting the audio performance characteristics of the transducer.
