Latest Patents

One of Crews' latest patents is titled "Method and system for hot docking a portable computer to a docking." This invention allows a portable computer to be inserted into or removed from a docking station without concern for the operational state of either device. The hot docking sequence is performed by establishing a direct connection to the primary PCI bus, minimizing the risk of system damage, file damage, or data loss. This process can be executed while the portable computer is powered on and actively running. Additionally, the invention prevents glitches in pre-existing pins and introduces four new pins to facilitate this novel hot docking sequence. The reverse process, known as hot undocking, can also be performed easily by reversing the docking sequence.

Another significant patent by Crews is the "Dynamic arbitration system and method." This invention provides a dynamic arbitration system for controlling data transfer between primary and secondary buses in a personal computer. It features master and target components on both buses, with primary and secondary bus arbiters included in a bridge circuit. Initially, these arbiters operate independently in a concurrent arbitration mode, which avoids interruptions on the primary bus during secondary-to-secondary transfers and optimizes bandwidth. When a secondary-to-primary bus data transfer is detected, the bridge circuit switches the arbiters to an interlocked mode, maintaining this mode until the next secondary-to-secondary cycle is detected.
