Latest Patents

One of St Jacques' latest patents is for a Magnetic Induction Type Transducer Means. This invention is designed to convert mechanical forces into corresponding electrical signals. In one embodiment, the transducer takes the form of a writing instrument used in a user identification system. The time-varying force between the instrument and a writing surface generates a waveform characteristic of the individual writing. The transducer consists of first and second core members interconnected by a resilient member, operatively coupled to a coil whose inductance varies according to the forces generated during writing. This coil is linked to an oscillator, producing a frequency that changes in accordance with the varying inductance, ultimately generating the waveform.

Another significant patent is for a Thermal Printer System. This system includes a means for generating heated air and controlling its application to a thermally sensitive recording medium. In one embodiment, the invention features a means for ionizing a column of gas and a method for attracting or repelling the ionized gas along a desired path in response to a control signal. Along this path, there is a means for heating the gas, with a thermally sensitive recording medium positioned to intercept the column of heated gas, creating a record based on the control signal.
