Abstract: A portable media device holder has a mounting plate with corner mounting brackets to hold a portable media device such as a smart phone or tablet computer. A ball joint is used to connect the mounting plate to a forearm mounting portion that enables the user to position the device at a selected angle. A hook and loop fastening strap is used to releasably hold the forearm mounting portion to the user's forearm. A handle projects downward from the forearm mounting portion that allows a user to hold and control the portable media device holder. In one embodiment, a plurality of cooling holes are provided to enable the device to operate at a cooler temperature. Additionally, breathing holes may be provided to make the forearm mounting portion more comfortable to wear. The forearm mounting portion may be padded for additional comfort.

Abstract: A subsurface reservoir may be characterized and/or monitored based on fluid injection. For example, fluid may be injected into the reservoir, and data (e.g., seismic data, geodetic data, pressure data) relating to the injected fluid in the reservoir may be used to identify characteristics of the reservoir and/or to monitor the injected fluid in the reservoir. In some aspects, air or another type of surrogate fluid is injected into the reservoir, and the reservoir's viability as a carbon dioxide sequestration site can be analyzed based on response data collected from the reservoir. In some aspects, carbon dioxide is sequestered in the subsurface reservoir, and three-dimensional geodetic response data is collected and used to monitor and/or facilitate quality control.
