Abstract: Battery enclosures and electronic devices having a battery enclosure are described herein. In one example, a battery enclosure includes a shell, a battery positioned within an internal volume of the shell, and a fire-retardant composition positioned on an outer surface of the shell, a first inner surface of the shell, between the first inner surface of the shell and the battery, or a combination thereof. In certain examples, the shell and/or fire-retardant composition are configured to provide a thermal seal or protection barrier between components (e.g., a battery) positioned within the battery enclosure and components of the electronic device positioned outside of the battery enclosure.

Abstract: A computer device may include one or more electronic components located in a passive cooling zone. A wall divides the passive cooling zone from an active cooling zone and acoustically isolating the active cooling zone from the passive cooling zone. A heat sink attached to at least one of the one or more electronic may extend from the passive cooling zone to the active cooling zone through the wall. At least one noise emitting component may be located in the active zone. A method of controlling noise in the computer device may include determining, by a processor of the computer device located in the passive cooling zone, a noise frequency of a noise emitting component located within an active cooling zone of the computer device. The processor may control a speaker within the active cooling zone to emit anti-noise cancelling the noise frequency.

Abstract: A thermal venting device is provided that includes a plenum including an inlet port and a plurality of outlet ports, the plenum being substantially fluidically sealed except for the inlet port and the plurality of outlet ports, the inlet port including an inlet fan configured to pressurize the plenum, each of the plurality of outlet ports being configured to direct airflow from the pressurized plenum toward different electronic components of a plurality of electronic components, and each of the plurality of outlet ports including respective resistive elements having varied airflow resistances configured to bias airflow through the plurality of outlet ports.

Abstract: Honeycomb body interdigitating mixers have parallel cells extending along a common direction, the mixer comprising a first fluid path extending within a honeycomb body perpendicular to the common direction, at least a high aspect ratio portion of the first fluid path having an aspect ratio of height in the common direction to width perpendicular to the common direction and to the first path direction of at least 3:1, and a second fluid path extending perpendicular to the common direction, the second fluid also having a high aspect ratio portion having an aspect ratio of at least 3:1, wherein the first fluid path is fluidically connected to the second fluid path within their respective high aspect ratio portions via a group of apertures, the group extending in the common direction, the group of apertures taken together having a ratio of height to width of at least 3:1.

Abstract: A honeycomb extrusion body has multiple cells extending along a common direction from a first end of the body to a second end of the body. The cells are separated by cell walls, and the body has at least one fluid path defined within a plurality of said cells. The fluid path includes one or more apertures, through respective cell walls between cells of one or more respective pairs of said plurality of cells. Each aperture has an aperture width measured perpendicular to the common direction of 90% or less of a cell wall width of the respective cell wall measured perpendicular to the common direction. Optionally one or more of the plurality of cells has at least two cell walls each having an aperture at the same position in the common direction. As a further option, these apertures may be offset from the respective centers of their respective walls in the same rotational direction about a central axis of the cell.

Abstract: A honeycomb extrusion body (20) is provided having multiple cells (22) extending along a common direction from a first end (26) of the body to a second end (28) and separated by cell walls, the body having at least one fluid path (32) defined within a plurality of said cells, the fluid path having including at least one direction—reversing bend (14) at which the path on entering the bend includes two or more separate cells (22A) and at which the path on leaving the bend includes only one cell (22B). The body desirably includes first and second input ports, the first fluid input port being in fluid communication with one of the two or more separate cells and the second fluid input port being in fluid communication with another of the two or more separate cells.

Abstract: A method of bonding an electrical component to a substrate includes applying solder paste on to a substrate. Solder preform has an aperture is formed therethrough and is then urged into contact with the solder paste, such that solder paste is urged through the aperture. An electrical component is then urged into contact with the solder preform and into contact with the solder paste that has been urged through the aperture, thereby bonding the electrical component, the solder preform, and the substrate together to define a reflow subassembly.

Abstract: Honeycomb body interdigitating mixers are disclosed along with methods for producing them, the honeycomb body having parallel cells extending along a common direction, the mixer comprising a first fluid path extending within the honeycomb body along a first path direction perpendicular to the common direction, the first fluid path defined within a first plurality of said cells, at least a high aspect ratio portion of the first fluid path having an aspect ratio of height in the common direction to width perpendicular to the common direction and to the first path direction of at least 3:1, and a second fluid path extending within the honeycomb body along a second path direction perpendicular to the common direction, the second fluid path defined within a second plurality of said cells, at least a high aspect ratio portion of the second fluid path having an aspect ratio of height in the common direction to width perpendicular to the common direction and to the second path direction of at least 3:1, wherein the f

Abstract: The invention provides devices and methods for increasing the degree of mixing of fluids, including under conditions of laminar flow and turbulent flow. In one embodiment, mixing of fluids using the invention's devices and methods is increased by splitting the flow of at least one of the fluids into two or more inlet channels. This is optionally followed by further splitting and merging (e.g., using one or more split and merge (SAM) mixer) the fluids.
