Front End Integrated Antenna for use in Wireless Communication Systems
This portfolio of patents covers the use of quantum tunneling in metal insulator devices to make high speed electronics. These low cost, nano-scale devices take performance beyond the physical limits of semiconductors. This metal-insulator technology can be integrated into supporting CMOS chip dies, or manufactured on a wide range of other substrates. Natively operating from DC to 3 THz, this technology is a compact, practical replacement for costly compound semiconductors in GHz applications and cryogenic devices in the emerging THz field.
Rotatable Head for Scanning Probe Microscopy
A new technology developed by the Navy, consolidating numerous circuit boxes onto one rotating measurement array. The new multi-tip scanning probe can rotate tips rather than requiring the changing out of tips to make each measurement, allowing more information to be accurately obtained for each sample by allowing the numerous different tips to interact with the same measurement location. A cost savings may be realized also as the consolidation of circuity during production will also occur.
Biomimetic Flapping-Wing Micro Air Vehicles US Patents 9,428,269 and 8,700,233
A tail-less, biomimetic FWMAV that is controlled by utilizing the motion of the flapping wings themselves. By manipulating a few variables that govern the periodic motion of two wings, the time-averaged forces and moments that are applied to the FWMAV can be directly controlled. A resulting implication is that the number of vehicle degrees of freedom controlled can exceed the number of actuators that physically exist on the FWMAV, thereby shifting complexity from mechanical elements to software. Present levels of development allow roll and yaw rotations and horizontal and vertical translations to be controlled using two brushless DC motors or piezoelectric actuators that drive each wing independently.
Solid electrolyte rechargeable lithium battery
A lithium ion battery cell. The lithium ion battery cell includes a lithium-based anode, a cathode, and a solid-state electrolyte positioned between the lithium-based anode and the cathode. The cathode comprises an alkylammonium cation lithium phthalocyanine anion complex. The solid-state electrolyte comprises an alkoxyalkylammonium cation lithium phthalocyanine anion complex.
Amplifying a Digital Signal
This technology enables all-digital power amplification suited for small, battery operated devices. Utilizing a sleep mode for the switching amplifier prolongs the battery life and increases efficiency in power usage. Reduced electromagnetic interference (EMI), which can degrade performance in surrounding elements, allows the amplifier to be employed without additional shielding. Both of these qualities make the system easier to conceal and reduce the cost of production.
Apparatus and method to prevent side channel power attacks in advanced encryption standard
The present invention provides an apparatus and method for obscuring round one power consumption of hardware i mplementation of the AES algorithm. Additional hardware circuitry will provide consistent power consumption during round one of the AES algorithm. This prevents the opportunity to determine the AES key value during a side channel p ower attack.
Seeded Raman amplifier in linear configuration for laser applications in the 1100-1500 nm spectral range
AFRL has developed a Raman amplifier having a novel design enabling high Raman conversion efficiencies and output powers in addition to linewidths, which can be controllable by a seed source. In this technology, a rare-earth-doped Raman amplifier can be spliced directly onto a Raman resonator system. To increase the efficiency of the system, a highly reflective Bragg grating centered at the pump wavelength can be included downstream from the Raman fiber to enable reflection of any unused pump light back through the Raman fiber. This offset can be accomplished in various ways to include temperature, bending, stretching, etc.
High efficiency, low voltage, low L-band, mega-watt class magnetron
AFRL has developed a conventional (non-relativistic) magnetron that provides megawatt-levels of power. The magnetron includes a fourteen vane slow wave structure that surrounds a fourteen turn helical cathode.
