Latest Patents

Coleman's latest patents include a method of making an improved pyroelectric sensor. This device features a thin strip of pyroelectric material, with one side coated in a continuous layer of metallic material to form an electrode. The opposite side is equipped with at least a pair of electrodes, which are electrically connected to a differential amplifier. An energy filter material is applied over the continuous electrode, allowing it to be sensitive to a specific energy frequency band while absorbing and converting other energy into heat. This heat is quickly conducted into the pyroelectric material, resulting in a voltage change that can be used to energize an alarm signal or indicate the size and movement of an energy source, such as a human body. The novel method of fabrication reduces handling problems and costs, making the device more efficient.
