| 20100106225 | Transcutaneous Power And/Or Data Transceiver - A device for communicating electric signals across the skin layer ( | 04-29-2010 |
| 20100185280 | ROTARY BLOOD PUMP AND CONTROL SYSTEM THEREFOR - A pump assembly and estimation and control system therefor, the pump adapted for continuous flow pumping of blood. In a particular form, the pump is a centrifugal pump wherein the impeller is entirely sealed within the pump housing and is exclusively hydrodynamically suspended therein against movement in three translational and two rotational degrees of freedom as the impeller rotates within the fluid urged by electromagnetic means external to the pump cavity. Hydrodynamic suspension is assisted by the impeller having deformities therein such as blades with surfaces tapered from the leading edges to the trailing edges of bottom and top surfaces thereof. | 07-22-2010 |

| 20080258657 | Tuning Dc Brushless Motors - A method of tuning a DC brushless motor, wherein measurement of back EMF voltage is used to detect changes in the torque requirements caused by variation in the operating conditions of the DC brushless motor, the method including varying the timing of the driving signals to the motor to compensate for the changes in the torque requirements. | 10-23-2008 |
| 20100036487 | Blood Pump With An Ultrasound Transducer - A blood pump including a ultrasonic sensor mounted in or on a blood contacting surface of said blood pump. The ultrasonic sensor measures blood velocity and reports information to a blood pump controller and wherein the ultrasonic sensor is directed to measure blood velocity in an inflow cannula connected to the blood pump. | 02-11-2010 |

| 20110015465 | CONTROL SYSTEMS FOR ROTARY BLOOD PUMPS - The present invention generally relates to a control system for a rotary blood pump adapted to move blood in a patient. The control system comprises a means for measuring and varying the speed of the pump and a means for measuring the pulsatility index of a patient, and the control system is adapted to maintain the pulsatility index at or near a predetermined value by varying the speed of the pump. The pulsatility index is derived from the amplitude of the actual pump speed over a predetermined time period. Optionally, also, the control system can calculate the second derivative of instantaneous speed of the rotary blood pump and use the calculation of the second derivative of instantaneous speed to detect a suction event, and help prevent it. | 01-20-2011 |

| 20090162144 | Tidal Flow Power Generation - A structure for a tidal flow energy generation system is fabricated from tubular framework having tubular modules with mounts for respective tidal flow turbine nacelles. The node modules include tubular limbs extending in transverse directions and elongate tubes and provided to interconnect with the tube limbs of the node modules. The structure can be pre-fabricated and transported to a location for deployment. The structure can be deployed by means of hovering the assembled structure to the seabed, for example by means of flooding the structure. | 06-25-2009 |

| 20110284323 | ROPE HANDLING DEVICE WITH SECONDARY LOCKING FEATURE - Rope handling devices that can be used for belaying, descending and rappelling are disclosed and provide a secure lock off without requiring the use of specialized knots. A secondary rope lock off feature, which provides for locking the ends of two ropes using a single snap link is also disclosed. In general, rope handling devices of the present invention have a body with at least one closed-ended slot and at least one open-ended slot. A loop of rope may be passed through the closed-ended slot(s) from an upper area and retained within the closed-ended slot by attachment of a first snap link to the loop of rope from below the lower area of the slot. A brake strand of rope may be positioned within the open-ended slot to aid in arresting a fall or lowering a climber. Further, the brake strand may be entrapped within the open-ended slot by attaching a second snap link through at least one aperture proximal to the open-ended slot. | 11-24-2011 |
