20100047753 | Vascular-Access Simulation System with Receiver for an End Effector - The illustrative embodiment is a simulation system for practicing vascular-access procedures without using human subjects. The simulator includes a data-processing system and a haptics interface device. The haptics device provides the physical interface at which an end effector (e.g., medical instrument, such as a needle, catheter, etc.) is manipulated to simulate needle insertion, etc. In accordance with the illustrative embodiment, the haptics device includes a receiver. The receiver receives the end effector when it's inserted by a user into the haptics device. Sensors that are associated with the receiver monitor the motion and position of the end effector, generate signals indicative thereof, and transmit the signals to the data processing system. The signals are processed to determine the effects of manipulation of the end effector. In some embodiments, the signals are processed to determine the various resistive forces that would arise if the user were manipulating a needle/catheter through actual human anatomy. Responsive to this determination, the receiver generates forces that the user experiences as a resistance to continued advance (insertion) of the end effector. Simulated results are displayed by the computer system. | 02-25-2010 |

20090004981 | HIGH EFFICIENCY DIGITAL TRANSMITTER INCORPORATING SWITCHING POWER SUPPLY AND LINEAR POWER AMPLIFIER - A novel apparatus and method of improving the power efficiency of a digital transmitter for non-constant-amplitude modulation schemes. The power efficiency improvement mechanism of the invention leverages the high efficiency of a switched-mode power supply (SMPS) that supplies the high DC current to the transmitter's power amplifier, while compensating for its limitations using predistortion. The predistortion may be achieved using any suitable technique such as digital signal processing, hardware techniques, etc. A switched mode power supply (i.e. switching regulator) is used to provide a slow form (i.e. reduced bandwidth) of envelope tracking (based on a narrower bandwidth distorted version of the envelope waveform) such that the switching regulator can use a lower switching rate corresponding to the lower bandwidth, thereby obtaining high efficiency in the switching regulator. The resulting AM-AM and AM-PM distortions in the power amplifier are compensated through predistortion of the digital amplitude modulating signal which dictates the envelope at the PA input. Similarly, the phase modulation is also compensated prior to the PA, such that once it undergoes the distortion in the PA, the end result is sufficiently close to the desired phase. | 01-01-2009 |
20100244976 | Clock Spreading Systems and Methods - Clock spreading systems and methods are disclosed. In one embodiment of the invention, a clock spreading system is provided in an integrated transceiver system that comprises a base band control system and a transceiver coupled to the base band control system.

20100187324 | Method and System for Scent Delivery - A scent-delivery system is disclosed that utilizes as least one of (1) a venturi-effect delivery device for promoting evaporation of volatile compounds or (2) a pendulum for energy-efficient movement of solid or liquid forms containing the volatile compounds. When the venturi-effect delivery device is used, a flow of air therethrough drives the evaporation of volatile compounds. The pendulum can be used to move the venturi-effect delivery device to generate the relative movement between the air and the device, hence creating a “flow” of air. | 07-29-2010 |

20150251351 | REMOVE AND REFILL METHOD AND APPARATUS FOR LAMINATED OBJECT MANUFACTURING - An apparatus and method of manufacture for an integral three-dimensional object of unlimited complexity formed from individually contoured laminations (layers) produced from thin sheet materials that are stabilized on a removable carrier and formed both along and across the sheet material prior to stacking the contoured laminations in precise registration to one another. The waste material surrounding the laminations and the carrier is separated from the desired object. An optional method includes refilling the space surrounding the layers with another material and leveling the upper surface of the laminations. The process of forming the contoured laminations, separating the waste material, bonding, and stacking is continued until the construction of the desired three-dimensional object is complete. | 09-10-2015 |

20100232878 | Universal Framed Cofferdam - Universal Framed Cofferdam has prefabricated skeletal steel space framing formed from multiple steel vertical pipes and two levels of horizontal diaphragm trusses rigidly connected to pipe columns. Beams of each diaphragm truss are attached to vertical pipes of the framing with rigid moment connections creating a rigid space frame of the perfectly round form that is used as a false work of the Cofferdam. Wales of the Cofferdam and short pieces of the flat sheet piling are attached to the vertical pipes forming a skeleton of the Cellular structure. The Skeleton of the Universal Framed Cofferdam is prefabricated in the convenience of the Dry Dock and than floated to the site. Buoyancy of the framing allows Cofferdam skeleton transportation without using the barge or otherwise necessary floating devices. Once brought to the site of installation Cofferdam skeleton is installed vertically in position and leveled on the bottom of the river bed. If necessary river silt can be jetted and pumped out of pipe annular space and pipe columns of framing can be simultaneously lowered in position by using vibro—hummer. After space framing installation, rock sockets are predrilled through the annular space of vertical pipes and rock anchors installed. Sheet pile skin of the Cofferdam installed between pipe columns concludes Cofferdam Can erection. Universal Framed Cofferdam Can than filled with compacted gravel and becomes a Hybrid Gravity Caisson/Columnar water front or marine structure that has the best features of the Conventional Cellular Cofferdam and of Columnar Dolphin structure. It has enhanced sliding and overturning stability provided by Rock anchors preloaded by Cofferdam granular fill and has effective mechanism that prevents concave or convex surface of rupture failure that may be suffered by conventional Cellular Cofferdams, and has mechanism that more effectively resists deep surface sliding failure of the Cofferdam base. | 09-16-2010 |
