Peter A Budni, Peter A Ketteridge: Low quantum defect holmium fiber laser. Daniel Long, BAE Systems, January 4, 2007: US20070002905-A1

A directly pumped, un-sensitized, holmium, quasi-two level fiber laser is disclosed that is doped with Holmium active ions between 0.1 and 2.0 percent by atomic weight. This yields greater energy efficiency from the laser because up-conversion losses are minimized, mismatches created by sensitizer i ...

Peter A Budni: Spectral modulation in an optical wavelength converter. Daniel Long, BAE Systems, February 20, 2003: US20030035201-A1

Wavelength conversion apparatus is described that utilizes a Kerr cell to modulate the polarization of a pump laser beam having a first wavelength before the beam is input to a optical parametric oscillator/amplifier wavelength converter to generate a laser beam having a second wavelength. By modula ...

Rachel E Learned: Method and apparatus for optimizing tree pruning in a multiuser detector. Daniel Long, BAE Systems, January 29, 2004: US20040017863-A1

A multi-user decoder is disclosed in which interfering users are assigned to levels of a decoding tree constructed in the decoder dependent on the power levels of the user's received signals and for each symbol interval. By building the decoding tree in this manner for each symbol interval, a reduce ...

Diane G Mills: Method and apparatus for random shuffled turbo multiuser detector. Daniel Long, BAE Systems, October 30, 2003: US20030204808-A1

A multi-user turbo decoder combining multi-user detection and forward error correction decoding is disclosed in which randomly ordered indices are assigned to interfering users before a decoding tree is constructed in the multi-user decoder for each symbol interval for every iteration and for each n ...

Diane G Mills: Method and apparatus for improved turbo multiuser detector. Daniel Long, BAE Systems, October 16, 2003: US20030193966-A1

A multi-user turbo decoder combining multi-user detection and forward error correction decoding is disclosed that utilizes iterative decoding of received, interfering signals, and the construction of a decoding tree of the decoder is changed for each iteration of the decoding based on the previous c ...

Jonathan Maimon, Murty S Polavarapu: Integrated resistor having aligned body and contact and method for forming the same. BAE Systems Information and Electronic Systems Integration, Daniel Long, Graybeal Jackson Haley, March 4, 2003: US06529403

An integrated resistor includes a resistor body region and a resistor contact region that is aligned with the body region. Because the resistor includes an aligned body and contact, it often occupies a smaller area than prior integrated resistors having a similar resistance value. A method for formi ...
