Patent number: 5556029Abstract: A method of dissipating hydrometeors (clouds) that includes transmitting electromagnetic radiation (e.g., light energy, from the sun, for example) that is absorbed by water vapor into the cloud to be dissipated and continuing the transmission of such energy into the cloud until it dissipates. The source of electromagnetic radiation can be a large mirror located on the surface of the earth, that reflects sunlight into the cloud to be dissipated. In a still more specific embodiment of the invention, the wind speed, direction, cloud altitude and sun movement relative to the earth is tracked to determine the mirror orientation and tracking necessary to disperse a particular cloud or clouds. In addition, an array of earth-mounted mirrors could be utilized in a coordinated fashion to dissipate a group or larger volume of clouds.Type: GrantFiled: September 12, 1994Date of Patent: September 17, 1996Inventor: Gary B.

Patent number: 5554937Abstract: A highly accurate system to measure the level of material in a vessel. A probe is provided in the vessel. The vessel and the probe are at different potentials so as to create a capacitance therebetween. The air and materials in the vessel act as dielectrics. As the material level varies, so does the capacitance. This capacitance is subjected to a charge-discharge-charge cycle yielding integrated net neutral charge. The duration of the cycle is compared to a reference time to determine capacitance, which is proportional to the level of material in the vessel.Type: GrantFiled: May 15, 1995Date of Patent: September 10, 1996Assignee: Penberthy, Inc.Inventors: Gary G.

Patent number: 5535502Abstract: An improved explosively operated separation joint as well as a process for manufacturing it are disclosed. In the present invention, a hollow-form extrusion is used to provide both sides of a separation joint, each side being attached to both of the two structures. Each end of the joint is attached to a respective one of the two structures. A stainless steel tube is inserted into the hollow portion of the extrusion. The extrusion then is rolled to form a portion of a ring. An explosive core covered by an elastomeric sheath is inserted into the length of the tube. The ends of the ring then are connected to and sealed by an initiation manifold. The manifold provides an interface between each of two flexible confined detonating cords ("FCDCs") with a respective end of the explosive core. The manifold includes a barrier between the ends of the explosive core and the two FCDCs that prevents sympathetic damage to either end of the explosive core and the associated FCDC by the detonation of the other.Type: GrantFiled: September 2, 1994Date of Patent: July 16, 1996Assignee: Orbital Sciences CorporationInventor: Gary N.

Patent number: 5524888Abstract: A gaming machine uses a time-based method for generating game results having nonuniform probability. The gaming machine employs an addressable memory in cooperation with a counter and a clock. The clock generates a very fast series of pulses, and includes a digital-to-analog converter. The counter holds a number representing one of the possible reel stop positions and counts the clock's pulses, so that with each pulse, the value of the counter advances by one. To vary the odds that a particular reel stop position will be selected, the clock's pulses do not come at even intervals. Rather, the clock is responsive to a digital input signal to control how long it will allow a particular number to remain in the counter before the next clock pulse. The binary numbers which are used to control the clock are stored in memory. The memory accepts as input the current value of the counter. Thus, when the counter is incremented, the memory provides the binary number associated with the new counter value.Type: GrantFiled: April 28, 1994Date of Patent: June 11, 1996Assignee: Bally Gaming International, Inc.Inventor: Raymond Heidel
