Latest Patents

One of his latest patents is an amplitude modulation detector. This device utilizes peak detection to identify signals effectively. It includes a Customer Premise Equipment Alert Signal (CAS) detection apparatus and a caller information detection apparatus. The CAS detection apparatus comprises a mixing unit, an amplitude modulation detection unit, and a frequency discriminating unit. The mixing unit combines multiple frequency components of the input signal to create an amplitude modulated signal. The amplitude modulation detection unit measures the envelope of this signal, while the frequency discriminating unit determines if the frequency of the envelope falls within a predetermined range, allowing for accurate detection of the CAS.

Another significant patent is the caller-ID demodulation apparatus and method using multiple thresholds. This apparatus features a zero crossing detector that generates pulses at points where the modulated caller ID information crosses zero. It also includes a data extractor that computes the zero crossing interval and compares it with multiple thresholds to generate extracted data. A clock generator is responsible for producing a data recovery clock signal, which is crucial for accurately recovering the extracted data.
