Latest Patents

One of her latest patents is titled "Fast frequency hopping spread spectrum for code division multiple access communication networks (FFH-CDMA)." This invention presents an improved method and apparatus for optical and radio frequency implementation of fast frequency hopping spread spectrum communication for code division multiple access systems. The method effectively eliminates the need for frequency hopping synthesizers in both the transmitter and receiver. In this system, a pool of CDMA users shares a channel characterized by a number of available frequencies. Each user is assigned a subset of frequencies, which are selected and ordered in time according to their unique code. The transmitter modulates a broadband source, concentrating the energy assigned to a data bit within a short interval of the bit period. The resulting output is an FFHSS signal composed of sub-pulses, each centered at different frequencies.

Another significant patent is the "Active cooperative tuned identification friend or foe (ACTIFF)." This optical identification friend-or-foe system for vehicles includes a responder optical head located on each friendly vehicle. The responder head consists of small panels arranged in an array, with surfaces angled to each other. These panels are coated with laser paint that emits radiation at selective wavelengths when exposed to an interrogation pump beam. This system allows for the identification of vehicles through the detection of these wavelengths.
