Latest Patents

One of Cruickshank's latest patents is titled "Methods and apparatus for full I/O functionality and blocking of backdrive current." This invention describes an input/output (I/O) port designed for electrical interconnection with multiple similar ports. It includes an input read circuit, an output drive circuit, and a control circuit that allows the port to switch between input and output modes. A key feature of this patent is the back drive current protection circuit, which prevents backdrive currents from other active processors when the processor is in a powered-down state, while still allowing full functionality when powered up.

Another significant patent is for an "Apparatus with reconfigurable counter includes memory for storing." This invention features a reconfigurable counter that includes first and second memories connected via a common bus to a microprocessor. The microprocessor controls the configuration and reconfiguration of the counter. The programmable hardware array can emulate various counter types, and the first memory stores multiple counter configuration profiles. This allows users to select different counter modes, such as up-down counter mode and pulse direction counter mode, enhancing the versatility of the counter.
