  • Patent number: 8281686
    Abstract: An eddy-current actuated balancer includes a barrel having a locating wall at one end thereof; two balancing wheels mounted around the barrel and carrying a respective counterweight at the border, a washer set between the balancing wheels, an elastic ring and a lock ring and a pulsed magnetic field generator mounted on each balancing wheel. The balancing wheels, the washer and the elastic ring are clamped between the locating wall of the barrel and the lock ring. Each pulsed magnetic field generator is controlled to generate a pulsed magnetic field acting upon the associating balancing wheel during its rotation for inducing an eddy current that causes the associating balancing wheel to make an angular displacement relative to the barrel for balance adjustment.

  • Publication number: 20120253679
    Abstract: Methods of and apparatus to perform a drawdown of a formation fluid in a downhole environment are disclosed. An example method includes contacting a borehole wall with a fluid communication device of a formation testing tool and performing a first type of drawdown to draw fluid into the fluid communication device. The method also includes detecting a breach of a mudcake on the borehole wall during performance of the first type of drawdown and performing a second type of drawdown to draw fluid into the sample probe in response to detecting the breach of the mudcake. The second type of drawdown is different than the first type of drawdown. Furthermore, the example method includes confirming the breach of the mudcake on the borehole wall during performance of the second type of drawdown.

  • Patent number: 8280380
    Abstract: Disclosed is a method and system for transmitting/receiving a neighbor base-station information message in a broadband wireless access system. A base station sets and transmits a neighbor base-station information message, which includes a specific flag field for limiting neighbor base-station information and a reserved field and omits iterative neighbor base-station information depending on a value set in the specific flag field, thereby increasing a transmission efficiency. A mobile terminal receives the neighbor base-station information message from the base station, checks the received message, and then updates an operator ID according to the value set in the specific flag field.

  • Patent number: 8268581
    Abstract: Compositions and methods are provided that are useful for predicting and controlling the stability of expressed polypeptides. The compositions and methods may be used to predict and as desired, increase or decrease the stability of proteins recombinantly expressed in mycobacteria, for example DesA3 expressed in Mycobacterium smegmatis. At the C terminus and the penultimate position, substitution to residues with charged side chains, large non-polar side chains, or no side chains can be used to reduce or inhibit the protein degradation. At the antepenultimate position from the C terminus, residues with no side chain or acidic side chains can increase the stability, i.e. reduce or inhibit the protein degradation. The combinational substitution of only the last three residues of polypeptides can make the polypeptides more stable during heterologous expression in mycobacterial hosts.

  • Publication number: 20120226145
    Abstract: A robotic system for overlapping radiofrequency ablation (RFA) in tumor treatment is disclosed. The robot assisted navigation system is formed of a robotic manipulator and a control system designed to execute preoperatively planned needle trajectories. Preoperative imaging and planning is followed by interoperative robot execution of the ablation treatment plan. The navigation system combines mechanical linkage sensory units with an optical registration system. There is no requirement for bulky hardware installation or computationally demanding software modules. Final position of the first needle placement is confirmed for validity with the plan and then is used as a reference for the subsequent needle insertions and ablations.
