Latest Patents
One of Patrick's latest patents is a flow control system for ink cartridges. This innovative system includes a reservoir maintained at a negative pressure, which is in communication with a printing system. As the printing system is activated, ink is expelled from the cartridge, drawing ink from the reservoir through capillary action. To prevent the reverse flow of air and ink into the reservoir, a control unit is integrated. This control unit features an ink conduit that communicates with a standpipe, and a medial section that includes an opening designed to receive a ball within the ink conduit. The ball is freely movable but larger than the opening, allowing for the outward flow of ink while preventing backflow.
Another significant patent by Patrick is a shipping package for semiconductor devices. This package is designed for flat lead transistors and features a raised flange that provides structural rigidity, preventing damage to the flat leads of the transistor. This innovation showcases Patrick's ability to address practical challenges in the packaging of sensitive electronic components.
