The first and second balloons may conform to a shape of a vaginal cavity when in their inflated conditions. A radiation detecting sensor and a motion detecting sensor may be positioned with the apparatus. | 06-10-2010 |
| 20100145379 | Rectal Balloon Apparatus with Pressure Relieving Lumen and Sensors - A rectal balloon apparatus comprises a shaft having a fluid passageway extending therethrough. A rectal gas relieving lumen may be positioned with the shaft for removal of rectal gas. A motion detecting sensor and a radiation detecting sensor may be positioned with the balloon, the shaft, and/or the rectal gas release lumen. | 06-10-2010 |
| 20100179582 | Minimally Invasive Rectal Balloon Apparatus - A rectal balloon apparatus has a shaft with a fluid passageway extending therethrough. A balloon is affixed over an end of the shaft such that the fluid passageway communicates with an interior of the balloon. The balloon has a laterally flat surface thereon when inflated. The laterally flat surface of the balloon has a longitudinal groove formed thereon. A valve assembly is affixed to the shaft at an end opposite the balloon. The valve assembly selectively allows a fluid to pass therethrough to move the balloon from a non-inflated condition to an inflated condition. A fluid introducing means is removably attached to the valve assembly to introduce the fluid into the valve assembly. | 07-15-2010 |

| 20100079175 | PHASE DOUBLER - A phase doubler driver circuit includes a first input for receiving a input PWM drive signal. First control logic generates a first output PWM drive signal and a second output PWM drive signal responsive to the input PWM drive signal. In a first mode of operation, alternating pulses of the input PWM drive are output as the first output PWM drive signal and the second PWM output drive signal respectively. In a second mode of operation, the input PWM drive signal is provided as the first output PWM drive signal when a second phase current associated with the second output PWM drive signal exceeds a first phase current associated with the first output PWM drive signal and the input PWM drive signal is provided as the second output PWM drive signal when the phase current associated with the first output PWM signal exceed the phase current associated with the second output PWM signal. Second control logic adds an offset to a falling edge of the first output PWM drive signal responsive to a difference between a first current associated with the first phase current and an average current and for adding the offset to a falling edge of the second output PWM signal responsive to a difference between a second current associated with the second phase current and the average current, wherein the average current comprises the average of the first current and the second current. Drive circuitry generates drive signals responsive to each of the first output PWM drive signal and the second output PWM drive signal. | 04-01-2010 |
