Abstract: Various aspects include ported wearable audio devices. In certain implementations, a wearable audio device includes: a first cavity; a second cavity; a third cavity; a driver disposed between the first cavity and the second cavity, the driver configured to provide an acoustic output; a first mass and/or resistive port connecting the second cavity and the third cavity; and a second mass and/or resistive port connected to the third cavity.

Abstract: This application describes a process for the preparation of flexible electrode-separator elements or assemblies, which includes the application of an electrode material on the separator. The electrode material comprises graphene, for instance produced by graphite exfoliation. The electrode-separator elements obtained by the process as well as their use in electrochemical cells are also described.

Abstract: A process for recycling an electrode material comprising graphene and an electrochemically active material is described. The process comprises a step of adding, in any order, water and a non-miscible solvent to the electrode material, thereby forming a biphasic system comprising an organic phase and an aqueous phase; and a step of separating and filtering the organic phase to recover graphene. The process optionally comprises additional steps of washing, drying, and/or thermally treating. Also described are electrodes including the recycled graphene, as well as the electrochemical cells and their uses.

Abstract: Described is a method or process for modifying the surface of carbon-coated electrochemically active materials such as complex oxides like olivine-type cathode materials. For instance, the surface of the carbon-coated powder material is modified to increase its hydrophobic characteristics. Also, specific groups may be grafted on the carbon surface of cathode material using the diazonium chemistry, for instance, by the spontaneous grafting of aryl ions generated in situ by the diazotization of an arylamine compound.

Abstract: A process for fabricating an electrochemical supercapacitor is disclosed herein. The process comprises depositing a carbon nanotube layer onto a first substrate; depositing a layer of metal oxide material onto the substrate forming a first electrode; depositing an electrolytic material onto the electrode; and joining the electrode to a first face of a solid electrolyte membrane such that the electrolytic material is disposed between the electrode and the electrolytic membrane. The carbon nanotubes, the metal oxide and the electrolytic material comprise distinct layers. An electrochemical supercapacitor fabricated by the above-referenced process is also disclosed.

Abstract: An improved rifle sling comprising of three buckles on an adjustable belt. An adjustment buckle having two serrated openings, a hooked buckle having two serrated openings and a hook at one end and a sliding buckle angled or bent at the middle with two smooth openings. The adjustment buckle allows the user to adjust the belt to a desired length. The sliding buckle is attached to one end of the belt and slides about the rest of the belt. The sliding buckle hooks onto the hooked buckle that is attached close to the other end of the belt when carrying the rifle close to the body. The sliding buckle is unhooked from hooked buckle adding slack to the belt as it slides across it allowing the rifle to be raised normally when it is to be deployed rapidly into a shooting position. The rifle can be carried across the back or front of a user's body.

Abstract: An electrochemical method and system for removing nitrate and ammonia in effluents, using an undivided flow-through electrolyzer, said electrolyzer comprising at least one cell, each cell comprising at least one anode and one cathode, the cathode being in a copper/nickel based alloy of a high corrosion resistance and a high electroactivity for nitrate reduction to ammonia and the anode being a DSA electrode of a high corrosion resistance and a high electroactivity for ammonia oxidation to nitrogen in presence of chloride.

Abstract: The present invention provides a method and system for processing media data on a host processor. The method and system involve receiving media data, generating clocking signals, transferring media data to host processor buffers, generating media transfer done interrupts for each media data stream and generating an override interrupt to indicate to the host processor to process the media data. The override interrupt has high priority and effectively indicates to the host processor to forgo all other scheduled tasks and to start processing the media data.
