Title: Soft error protected dynamic circuit
Inventor: CHU SAM GAT-SHANG
IPC: H03K19/096
Filed: 1999-01-18
Granted: 2001-05-28
Abstract: A method and apparatus is effective to preserve logic state potential levels in logic circuitry notwithstanding alpha particle collisions. Cross-coupled circuitry, including active devices, are implemented in a complementary logic circuit arrangement to hold current logic values in the event of a premature switching such as a switching that may be induced by alpha particle collision with the semiconductor logic circuit. Stabilizing transistor switching devices are arranged to sense an inappropriate or premature switching initiation and respond thereto by operating to maintain the appropriate logic levels within the logic circuitry. In one embodiment, the internal node of an upper circuit in a dual-rail logic circuit is connected to a gate terminal of a cross-coupled PFET device in the lower circuit. The cross-coupled PFET device is operable to sense an initiated untimely switching action in the upper circuit and effect a re-application of the holding PFET in the upper circuit to re-establish the appropriate logic potential levels in the upper circuit.

Title: Combustion dynamics control for variable fuel gas composition and temperature based on gas control valve feedback
Inventor: VANDERVORT CHRISTIAN L
IPC: F02C9/00
Filed: 1999-03-26
Granted: 2002-05-21
Abstract: An actual Wobbe Index is calculated for a turbine and compared to a reference Wobbe Index. By comparing the actual and reference Wobbe Indices and recognizing that the reference Wobbe Index has acceptable combustion dynamics, a measure of the combustion dynamics of the operating turbine can be obtained. To lower the possibility of combustion dynamics, causing combustor distress, a feedback signal is provided to change the temperature of the fuel gas provided the combustor. Since the Wobbe Index is a function of temperature and fuel composition, the variation in temperature can be effected to change the Wobbe Index to a reference Wobbe Index having known low combustion dynamics.

Abstract: An ophthalmic lens mold includes a first mold half having a front side and a back side. The front side defines an optical surface. A second mold half has a front side defining an optical surface. Upon alignment of the first mold half with respect to the second mold half so that the front oppose each other, a mold cavity is formed between the front sides to form an ophthalmic lens therein from a moldable material. The first mold half includes a first section that transmits during light and that extends from the back side to the front side. The first section includes at an area of the first mold half optical surface enclosed by an outermost circumstance of the ophthalmic lens. A second section is co-molded with the first section and blocks the light. The second section is disposed with respect to the first section so that the second section prevents the curing light incident to the back side from passing through the first mold half front side to the second mold half front side surrounding and extending radially outward of a boundary that includes the ophthalmic lens circumference and so that the first section passes the incident light to an area of the mold cavity bounded by and within the boundary.
