Latest Patents

Among his latest patents is the "Apparatus for safe installation and removal of a circuit board for hot swap applications." This invention provides a method for indicating and allowing the hot swapping of a circuit board. During both the insertion and extraction of a circuit board from a system, two input signals are generated from staggered pins located on the circuit board's connector. These inputs are processed through a NAND function implemented with transistors and output to two Schmitt trigger inverters connected in series. The output of this series connection goes high when both input signals are high and goes low when one of the input signals goes low. Additionally, a resistor-capacitor combination connected to the input of the first Schmitt trigger inverter ensures that the output signal remains high for a period of time after one of the input signals goes low. This feature prevents any damage or disruption of signaling caused by transient current and voltage fluctuations during the insertion or extraction of the circuit board. The output signal can be utilized in both single-ended and differential SCSI applications.

Another significant patent is the "State activated one shot with extended pulse timing for hot-swap applications." This invention shares similar functionality with the previous patent, focusing on the safe hot swapping of circuit boards. The design and operation are consistent with the principles outlined in his first patent, ensuring reliability and safety in electronic systems.
