  • Publication number: 20200306107
    Abstract: The foam and fiber composite can provide an absorbent article with improved dryness and an improved liquid distribution capability. The foam and fiber composite can be formed from at least two materials. The first material is an open cell foam material and the second material is a fibrous material. A plurality of the fibers forming the fibrous material can be fluid inserted into the open cell foam material thereby forming the foam and fiber composite. In various embodiments, the foam and fiber composite can be incorporated into an absorbent article as a component of an absorbent system located between a topsheet layer and a backsheet layer of the absorbent article.

  • Publication number: 20180209094
    Abstract: A method (10, 110) for cleaning fibers from a contaminated article is disclosed. The method (10, 110) can include providing a contaminated article comprising contaminates and at least one of fibers and filaments. The method (10, 110) can further include adding a plurality of magnetic particles (18, 118) to a first solution and pulping (20, 120) the contaminated article to separate the at least one of fibers and filaments from the contaminated article to provide dissociated pulped fibers. The method (10, 110) can further include applying a magnetic field (22, 122) to the suspension including the dissociated pulped fibers and removing (26, 126) at least some of the plurality of magnetic particles and at least some of the contaminates from the suspension. The dissociated pulped fibers can be dried (34, 134) to provide clean fibers.

  • Publication number: 20180202102
    Abstract: A method (10) for cleaning fibers from a contaminated article is disclosed. The method (10) can include pulping (20) a contaminated article to separate the fibers or filaments from the contaminated article in a first solution to provide dissociated pulped fibers. The method (10) can also include washing (26) the dissociated pulped fibers by forming a suspension comprising the dissociated pulped fibers from the contaminated article and a detergent, applying a magnetic field to the suspension, and mixing the suspension to wash the dissociated pulped fibers while applying the magnetic field to the suspension thereby forming washed pulped fibers. Contaminates can be removed from the suspension while washing (26) the dissociated pulped fibers. The washed pulped fibers can be rinsed and dried to provide clean fibers.

  • Patent number: 8762759
    Abstract: To reduce power consumption, a processor can be placed into a reduced power state. Before doing so, interrupt events can be designated as wakeup events. While the processor is in the reduced power state, if an event designated as a wakeup event occurs, then a signal is directed to a wakeup event handler instead of to an interrupt handler. In response to the signal, the wakeup event handler causes power to be restored to the processor, so that the event can be subsequently serviced.

  • Publication number: 20090204837
    Abstract: An efficient and effective power control system method are described with expedited recovery from a reduced power state. In one embodiment, a present invention power control system includes performing a reduced power detection process for detecting a reduced power state, wherein the reduced power state is associated with an expedited recovery; performing a reduced power state entry process; performing a recovery detection process for detecting a recover indication event; and performing an expedited recovery process in accordance with detection of a recovery indication event. The reduced power state entry process comprises saving an expedited recovery information in registers of an always on domain and putting an external memory in self refresh mode to preserve a system context while a chip is turned off.
