Abstract: The present disclosure is a battery capacity testing interface (BCTI) module. The BCTI module may be configured to test capacity of a battery unit, such as an individual battery or string of batteries. In one aspect of the present disclosure, the BCTI module may instruct a battery unit under test to release a controlled electrical discharge that is measured by the BCTI module. Once determined, battery capacity can provide insight into the battery life of the battery, as well as the ability of the battery to deliver a specified amount of current at a constant rate to a specified end voltage for a specified time. Advantageously, the BCTI module may operate with various types of battery monitors and may be employed to test various types of batteries, including lead-acid batteries and lithium-ion batteries.

Abstract: A substrate processing tool capable of detecting a gap and/or shifting of a substrate clamped to a clamping surface in a processing chamber based on observed behavior of RF power delivered to the processing chamber during processing. The behavior of the RF power is observed by comparing a voltage-current phase angle difference and/or impedance magnitude change between a real RF power component and a reactive RF power component of the RF power delivered to the processing chamber.

Abstract: A drill cuttings diverter system for distributing downhole drill cuttings inside a cuttings box, where the drill cuttings diverter system is equipped with a diverter conduit having a bottom that is concaved toward a side opening. The diverter conduit is rotatably inserted through an opening in the cuttings box so that the operator can rotate the side opening at the bottom of the diverter conduit to change the direction of the drill cuttings being fed into the cuttings box, and thereby prevent the drill cuttings from accumulating in a single pile inside the cuttings box.

Abstract: A microelectromechanical systems (MEMS) based heat engine capable of converting thermal energy gradients into mechanical or electrical energy, as well as its fabrication process is disclosed. This heat engine design consists of a stressed oscillating beam formed from a shape memory alloy (SMA) thin film. As the temperature of the beam changes, its shape changes due to the phase transformation of the shape memory alloy, causing it to oscillate between a hot source and a cold source. Due to the hysteretic behavior of the phase transformation, the oscillating SMA cantilever beam produces a net mechanical work output that may be either converted to electrical energy or mechanically linked to other MEMS devices.

Abstract: An aluminosilicate ceramic product or article and a method of forming the article from as-mined ore. The product is useful as a proppant in gas and oil well fracturing. The ratio, on a calcined basis, of alumina to silica is between approximately 2.2 to 4.0. The amount of iron in the product is controlled as a function of the alumina to silica ratio so as to produce products having less than ten percent (10%) crush loss when subjected to a force of 10,000 psi.
