Abstract: This disclosure describes techniques and systems for encoding instructions in audio data that, when output on a speaker of a first device in an environment, cause a second device to output content in the environment. In some instances, the audio data has a frequency that is inaudible to users in the environment. Thus, the first device is able to cause the second device to output the content without users in the environment hearing the instructions. In some instances, the first device also outputs content, and the content output by the second device is played at an offset relative to a position of the content output by the first device.

Abstract: A method and apparatus for an adaptable vehicle light mount is provided. A recess created within an interior of a heat sink fin array of the vehicle light allows associated mounting hardware to be embedded within the recess. A physical offset between the vehicle light and the associated vehicle may therefore be minimized to provide a shallower mounting profile. A tube may be incorporated into the recess so as to allow one or more vehicle lights to be mounted to a single mount point on a vehicle where the tube and associated mounting hardware are incorporated and function as part of the heat reducing components of the vehicle light.

Abstract: An axial flow electrolytic cell includes an outer layer made of a polyolefin material and formed as a tube. An outer layer liner lines an inside surface of the outer layer. The outer layer liner is formed as a metal tube. A middle layer is mounted inside the outer layer. The middle layer further includes a middle flow inlet and a middle flow outlet. The middle layer is formed as a metal tube. An inside layer is mounted inside the middle layer. The inside layer has an inside flow inlet and an inside flow outlet. The inside layer is formed as a middle tube. The first electrical connector is mounted to the middle layer at a middle layer connection. The first electrical connector passes through the outer layer and outer layer liner at an outer layer opening. A second electrical connector mounts to the outer layer liner and the inside layer.
