Patent number: 7191413Abstract: A method and apparatus for thermal testing of semiconductor chip designs is provided. One embodiment of a novel method for performing thermal testing of a semiconductor chip design includes calculating full-chip temperatures over the semiconductor chip design (e.g., to identify steep thermal gradients) and positioning temperature sensors within a corresponding semiconductor chip in accordance with the calculated full-chip temperatures (e.g., in the regions of steep thermal gradients). Thus, temperature sensors are strategically placed in the regions where they are most likely to be needed, according to calculated temperatures, rather than randomly positioned throughout a test chip.Type: GrantFiled: March 11, 2005Date of Patent: March 13, 2007Assignee: Gradient Design Automation, Inc.Inventors: Rajit Chandra, Lucio Lanza

Patent number: 6081239Abstract: A planar antenna that includes a high dielectric constant superstrate lens having a plurality of air holes that vary the actual dielectric constant of the lens to provide an effective dielectric constant superstrate lens. The holes can take on any shape and configuration in accordance with a particular antenna design scheme so as to optimize the effective dielectric constant for a particular application. In one particular design, the holes are formed in a random manner completely through superstrate lens, and the holes have an opening diameter less than 1/20th of the operational wavelength of the antenna. The holes act to vary the dielectric constant of the superstrate lens so that the resonant waves do not form in the lens, thus reducing power loss in the antenna. The holes are formed by a suitable mechanical or laser drilling operation.Type: GrantFiled: October 23, 1998Date of Patent: June 27, 2000Assignee: Gradient Technologies, LLCInventors: Kazem F.

Method for processing materials to change their texture, apparatus therefor, and resulting materials
Patent number: 5855941Abstract: Materials, for example, plant-based food products, are subjected to heat and pressure in a processing enclosure, wherein the pressure is greater than the pressure of the atmosphere. The heated, pressurized materials are then subjected to a pressure-reduction phase during which the pressure in the processing enclosure is reduced at a rate greater than 500 millibars per second and by an amplitude greater than 1 bar. The rapid pressure-reduction phase of the invention contributes to the production of processed materials having a slightly spongy structure that is due to the presence of micro-cavities that promote the recapture of subsequent moisture.Type: GrantFiled: July 12, 1996Date of Patent: January 5, 1999Assignee: GradientInventors: Karim Allaf, Nicolas Louka, Francis Parent, Jean-Marie Bouvier, Michel Forget -
