The present invention relates to a micro-lattice and, more particularly, to an ultra-light micro-lattice and a method for forming the same. The micro-lattice is a cellular material formed of interconnected hollow tubes. The cellular material has a relative density in a range of 0.001% to 0.3%, and a density of 0.9 mg/cc has been demonstrated. The cellular material also has the ability to recover from a deformation exceeding 50% strain.

Systems and methods for controlling an electrical drive such as is used with electric submersible pumps used in downhole oil production, wherein the drive automatically determines the proper phasing to drive the pump motor in a forward direction. In one embodiment, a method includes generating a drive signal having an initial phasing and driving the pump to establish a column of fluid in the borehole. The drive signal is then discontinued, allowing the column of fluid to fall through the pump and cause the pump to backspin and generate a signal having phasing corresponding to the reverse rotational direction. The forward phasing is then determined to be the opposite of the phasing corresponding to the reverse rotational direction. The pump can be restarted in the forward direction, or an operator can be notified of the proper phasing to produce forward rotation of the pump.

According to one embodiment of the present invention, a semiconductor device includes a first layer of dielectric material disposed upon an upper surface of a substrate of a semiconductor device and a first non-conductive layer of metal disposed upon an upper surface of the dielectric material. The first layer of dielectric material and the first non-conductive layer of metal act as an optical trap for electromagnetic radiation received by the first non-conductive layer of metal. In particular embodiments, the semiconductor device may further comprise a second layer of dielectric material disposed upon an upper surface of the first non-conductive layer of metal and a second non-conductive layer of metal disposed upon an upper surface of the second layer of dielectric material.
