Latest Patents

Fossaceca's latest patents include a "Clear channel selection system for a cordless telephone." This invention features a radio frequency (RF) signal transmitter/receiver system that comprises a pair of transmitter/receiver units. A microcomputer-based RF carrier detect system determines when an RF signal is present or absent. The RF carrier detect system is also responsive to noise interference signals at or near its currently-tuned receiving channel. During periods of inactivity, the RF signal receiver monitors its currently-tuned channel. Upon detection of noise interference or a determination that the currently-tuned channel is occupied, it initiates a fast scan operation to identify an unoccupied and relatively interference-free channel. It then transmits a command to its paired transmitter/receiver unit, causing it to tune to the newly-identified unoccupied channel.

Another significant patent is the "Microcomputer-based carrier detection system for a cordless telephone." In this invention, a microcomputer in a radio frequency (RF) signal receiver, such as a cordless telephone set, periodically samples a received baseband audio signal to determine its frequency content. The microcomputer uses at least one predetermined frequency threshold value. It determines that the RF signal is present if the output signal contains signals no higher in frequency than the frequency threshold value. Conversely, it determines that the RF signal is absent if the output signal contains signals higher in frequency than the frequency threshold value. This circuit is useful in either a base unit or a hand unit of a cordless telephone set.
