20100061034 | Low Voltage Power Supply for Spark Igniter and Flame Sense - A low voltage power supply circuit for intermittent pilot and/or direct spark ignition systems utilized in gas burning appliances is provided. The circuit utilizes a single transformer and a resonant circuit to supply power to both a flame sense circuit as well as the spark generation circuit. The resonant circuit allows the use of low power sources such as batteries or self-supplied voltage systems such as thermopiles or hydro generators. Recognizing that power draw from the low power source is high during a sparking event and recharging of a sparking capacitor, the flame sensing is suspended during the sparking event and for a short recharge time thereafter. | 03-11-2010 |
20100075264 | Redundant Ignition Control Circuit and Method - A redundant ignition control system and method for gas burning appliances is provided. The system utilizes a main processor and a supervisory processor to provide the redundant, fail safe operation of both the pilot valve and the main gas valve of the appliance. Three switching elements under the control of the two processors, as well as the use of high pass filters to block DC from the gas control valves provide redundant, fail safe operation. The use of variable duty cycle or frequency pulse width modulated signals enables use in low power applications and ensures system safety. Inclusion of a gas valve verification sequence, ignition sequence, burner monitoring sequence, and heat shutdown and standby sequences ensures safe, low power operation during normal control, and fail safe operation upon the failure of any component of the system. | 03-25-2010 |

20100101903 | VIBRATION ISOLATORS - Vibration isolators are provided that include a shaft, a first bushing, a second bushing, a first outer annular member, a second outer annular member, a first elastomeric member, a second elastomeric member, and a shim. The first elastomeric member is adapted to provide a first stiffness for damping a first vibration, and the second elastomeric member is adapted to provide a second stiffness for damping a second vibration, the second stiffness being greater than the first stiffness. | 04-29-2010 |
20100320358 | TWO STAGE VIBRATION ISOLATOR - A vibration isolating system is disclosed. The vibration isolating system comprises a passive mechanical system comprising a damping assembly, a first resilient member coupled in series with the damping assembly, and a second resilient member coupled in parallel with the series combination of the damping assembly and the first resilient member. The vibration isolating system further comprises a support member coupled in series with the passive mechanical system, a viscoelastic mount coupled to the support member, and a motion limiter coupled to the support member such that the passive mechanical system transmits a force to the support member when the passive mechanical undergoes longitudinal displacement greater than a predetermined displacement. | 12-23-2010 |
20120267506 | THREE PARAMETER, MULTI-AXIS ISOLATORS, ISOLATION SYSTEMS EMPLOYING THE SAME, AND METHODS FOR PRODUCING THE SAME - Embodiments of a three parameter, multi-axis isolator configured to limit the transmission of vibrations between a mass and a base are provided. In one embodiment, the three parameter, multi-axis isolator includes an isolator housing configured to be mounted to the base, opposing bellows sealingly mounted within the isolator housing, and a damper piston movably suspended within the isolator housing between the opposing bellows. The damper piston is configured to be coupled to the mass. The opposing bellows deflect with movement of the damper piston along multiple axes to limit the transmission of vibrations between the mass and the base. | 10-25-2012 |

20100331974 | Intraocular Kinetic Power Generator - An implantable kinetic power generator has an oscillating weight that is physically coupled to a first gear. A second gear with a rotor at its center of rotation is coupled to the first gear. A generating coil is located in close proximity to the rotor. An energy storage unit is electrically coupled to the coil. A shell suitable for implantation in the eye encloses these components. When the rotor rotates, energy generated by the coil is stored in the energy storage unit. | 12-30-2010 |
20100331977 | Electrical Amplification of Physiologic Signals For Accommodative IOL Control - A control system for an accommodative intraocular lens includes a sensing circuit for sensing a signal that controls a ciliary muscle of an eye and an amplifier circuit for amplifying the sensed signal. The output of the amplifier circuit is used to control an accommodative IOL. At least one electrode located in the vicinity of cranial nerve III, the ciliary ganglion, or the ciliary muscles is used to receive the signal that controls the ciliary muscles. A filter may also be included. | 12-30-2010 |
