Patent number: 9634183Abstract: A solution for designing and/or fabricating a structure including a quantum well and an adjacent barrier is provided. A target band discontinuity between the quantum well and the adjacent barrier is selected to coincide with an activation energy of a dopant for the quantum well and/or barrier. For example, a target valence band discontinuity can be selected such that a dopant energy level of a dopant in the adjacent barrier coincides with a valence energy band edge for the quantum well and/or a ground state energy for free carriers in a valence energy band for the quantum well. Additionally, a target doping level for the quantum well and/or adjacent barrier can be selected to facilitate a real space transfer of holes across the barrier. The quantum well and the adjacent barrier can be formed such that the actual band discontinuity and/or actual doping level(s) correspond to the relevant target(s).Type: GrantFiled: March 14, 2016Date of Patent: April 25, 2017Assignee: Sensor Electronic Technology, Inc.Inventors: Maxim S.

Patent number: 9617071Abstract: A non-contact lid sensor is provided for use with an oil field thief hatch and a latch. The sensor is mounted to the latch and comprises a reed switch. The latch pin is removed and embedded with a magnet with the magnet's north-south poles parallel to the pin's length so that the magnet triggers the reed switch. The reed switch is oriented so that it is perpendicular to the lower latch pin and the face of the sensor. The magnet and reed switch are aligned so that when the lid is closed the reed switch never sees the 0 Gauss line of the magnet. When the latch is in a closed position the reed switch allows the current to pass through the sensor and signal that the hatch is closed. The sensor system also allows for a Hall effect sensor to be used.Type: GrantFiled: January 27, 2015Date of Patent: April 11, 2017Assignee: SENSOR SOLUTIONS CORP.Inventor: David Lorenzen
