Patent number: 7555084Abstract: The present invention performs a digital computation with a lower than worst-case-required clock period (i.e., a faster clock), and at the same time performs the same computation with a larger, worst-case-assumed, clock period (i.e., a slower clock) on a second system with identical hardware. The outputs from the computations are compared to determine if an error has occurred. If there is a difference in the two answers, the faster computation must be in error (i.e., a miscalculation has occurred), and the system uses the answer from the slower system. In one embodiment, the present invention utilizes two copies of the slower system that each run half as fast as the main system. However, the two copies produce results in the aggregate at the same rate as the main system, which is running at a much faster rate than possible without the invention. Hence the present invention improves performance (e.g., speed), albeit with more hardware.Type: GrantFiled: August 11, 2005Date of Patent: June 30, 2009Assignee: The Board of Governors for Higher Education, State of Rhode Island and Providence PlantationsInventor: Augustus K.

Patent number: 7489965Abstract: A dynamically configurable clamping device for applying a desired electrical current to a tissue membrane includes an input lead electrically connected to the tissue membrane to provide a sensed signal indicative of voltage across the membrane. An input circuit includes an analog-to-digital converter, and is responsive to the sensed signal and provides a digitized signal indicative of the sensed signal. A digital signal processor executes selected program instructions to operate in a selected one of (i) a voltage clamp mode, (ii) a current clamp mode or (iii) a dynamic clamp mode based upon the state of a mode selection signal indicative of the selected operating mode. The digital signal processor provides a digital current command signal indicative of the current to be applied to the tissue membrane. An output circuit receives the digital current command signal, and generates a current signal indicative thereof. An output lead receives and applies the current signal to the tissue membrane.Type: GrantFiled: October 4, 2004Date of Patent: February 10, 2009Assignee: Board of Governors for Higher Education, State of Rhode Island and Providence PlantationsInventors: Ying Sun, Jiang Wu, Leon P.
