Abstract: Methods and apparatuses for dynamic power reduction in ultrasound systems are described. Subsystems including a first subsystem to be placed in a reduced power consumption state are determined. The first subsystem includes a receive path having a receiver to receive acoustic signals representing echoes. A control subsystem to control clocking of the receive path in response to at least one of a plurality of real-time signals is determined. The control subsystem is configured to provide one or more clocks to the receive path to turn on the receiver while valid echo signals are expected to arrive at the receiver At least one of the plurality of real-time signals indicates a state of imaging operations. The control subsystem is configured to provide one or more clocks to the receive path during a first mode based on the state of the imaging operations.

Abstract: Discrete particles of cellulosic material are flowable and meterable. They are easily dispersible in an aqueous or a dry medium. The particles comprise singulated cellulose fibers that have been densified. The particles have a density of at least 0.3 g/cc.

Abstract: Fiber treated with an organic nonpolymeric binder is combined with superabsorbent particles in order to bind the particles to the fiber. The nonpolymeric organic binder comprises binder molecules that include at least one functional group capable of forming a hydrogen bond or a coordinate covalent bond with the particles and at least one functional group capable of forming a hydrogen bond with the fiber. The superabsorbent particles have a hydrogen or coordinate covalent bonding functional site. The binder serves to bind the particles to the fiber through formation of hydrogen and/or coordinate covalent bonds.

Abstract: A binder is applied to particles which are then combined with fibers to bind the particles to the fibers. The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

Abstract: A process for making singulated pulp flakes is provided. The process includes dewatering liquid pulp stock to a consistency of about 30 to about 50% solids. The process includes initial flaking to break up the dewatered pulp bundles into semi-uniform flakes having a median size of from about 3 to about 5 mm3 and a consistency of from about 33 to about 55% solids. The process includes drying the flaked pulp to a consistency of from about 85 to about 97% solids. The process includes flaking a second time to separate the flakes that may have bonded during drying. The product “singulated” flakes then go to a baler for packaging. In another embodiment, the process includes blending the liquid pulp stock with at least one adjuvant prior to dewatering.

Abstract: The present invention is directed to a new form of pulp that is a flake having a specific size, density, and wet dispersibility. The flakes are easy to meter in specified quantities when adding to cementitious products, because bulk quantities of the flakes flow well in conduits and other enclosed containers. The pulp flakes can supply sufficient cellulose fiber to an extrusion process due to the flakes' high fiber density. The pulp flakes have a wet dispersability that is comparable to some pulp sheets that have not been hammermilled. In one embodiment of the invention, a pulp flake is provided that has a wet dispersion of from about 60 to about 240 counts as measured by a standard British disintegrator. Another embodiment of a pulp flake has a density of from about 0.3 to about 0.7 g/cc. In one embodiment, the pulp flake has a size of from about 3 to about 5 mm3.

Abstract: A highly densifiable wood pulp product is disclosed. In one embodiment, the densifiable product includes fibers having low coarseness, preferably having a fiber coarseness less than about 22 mg/100 m, and a densifying agent. In another embodiment, the densifiable product further includes fibers having coarseness greater than about 22 mg/100 m. Juvenile wood fibers are the preferred source of fibers having low coarseness. A densified pulp product formed by compacting a fibrous composite that includes fibers having a fiber coarseness less than about 22 mg/100 m, a densifying agent, and optionally, fibers having coarseness greater than about 22 mg/100 m is also disclosed. The pulp products can be advantageously incorporated into absorbent articles and can optionally further include superabsorbent material. Methods for forming the densifiable and densified fibrous products are also disclosed.

Abstract: Wet laid webs of cellulose fibers are treated with a fiber treatment composition that includes a polysaccharide. The polysaccharide is introduced into the web using a fiber treatment composition and a process that produces a wet laid web that exhibits desirable tackiness properties between adjacent sheets and within the web. Airlaid webs produced from the wet laid webs of the present invention are useful in absorbent articles such as diapers, feminine hygiene products, and wipes.
