Abstract: This disclosure provides techniques for treatment of aqueous matrices using electrolysis to produce soluble metals. An aqueous matrix of interest is passed through an electrolysis device with at least one consumable electrode, which dissolves under applied current, transferring a desired reagent to the aqueous matrix of interest. In one embodiment, the electrolysis device is used in a water delivery network to passivate hexavalent chromium (Cr6) and/or convert it to trivalent chromium; the electrode can be made of food-grade metal tin, which is electrolyzed to form a stannous reagent, which then reacts with the Cr6. The disclosed techniques provide for Cr6 passivation without requiring the use of concentrated acids or other harmful substances. Long term reagent generation efficiency can be enhanced through the use of cleaning processes which maintain a fresh electrode surface in contact with the aqueous matrix of interest.

The method additionally includes receiving, via the API and from an application running on the computing device, one or more values for one or more parameters of the plurality of parameters. The method further includes adjusting, by the operating system, the plurality of audio channels based on the received one or more values for the one or more parameters.

Abstract: A cutting assembly for a rock excavation machine having a frame includes a boom and a cutting device supported on the boom. The boom includes a first portion and a second portion, the first portion supported for pivotable movement relative to the frame. In some embodiments, the first portion includes a first structure extending along a longitudinal base axis and a second structure moveable relative to the first portion in a direction parallel to the longitudinal base axis, and at least one bearing supports the second portion for movement relative to the first portion. In some embodiments, the second portion is pivotably coupled to the first portion by a universal joint, and a suspension system including a plurality of biasing members may be coupled between the first portion and the second portion.

Abstract: Provided is a method that includes determining a device geolocation based on a satellite signal received by a weapon-tracking device and receiving a sensor reading using a sensor attached to the weapon-tracking device, wherein the sensor is sensitive to a use of the weapon. The instructions include determining that a change in the sensor reading satisfies a change threshold and, in response to a determination that the change threshold is satisfied, transmitting device state data to a wireless signal receiver via a wireless signal, wherein the device state data comprises a device identifier and the device geolocation. The instructions further include storing the device identifier and the device geolocation in a data server in communication with the wireless signal receiver and transmitting a message based on the device identifier and device geolocation to a client from the data server.
