  • Patent number: 10299872
    Abstract: A robotic surgical method comprises providing an instrument chassis having a proximal mounting section and a distal mounting section rigidly coupled to the proximal mounting section, an instrument guide assembly movably coupled to the distal mounting section, a pair of proximal actuators coupled to the proximal mounting section, and a linkage system operably interconnecting the proximal actuators and the instrument guide assembly. The method further comprises providing first control signals to one of the proximal actuators to cause the linkage system to move the instrument guide assembly in a first rotational degree of freedom, providing second control signals to the other proximal actuator to cause the linkage system to move the instrument guide assembly in a second rotational degree of freedom, and providing third control signals to the proximal actuators to cause the linkage system to move the instrument guide assembly in a third rotational degree of freedom.

  • Patent number: 10100754
    Abstract: A system and method for dynamically varying an amount slippage of a Torque Converter Clutch (TCC) provided between an engine and a transmission of a vehicle in response to non-powertrain factors. By varying a slippage output signal, the amount of TCC slippage between the engine and the transmission can be adjusted. Small amounts of slippage, relative to large amounts of slippage, provide (a) improved vehicle fuel economy, but (b) induce more powertrain noise and vibration in the vehicle cabin. By dynamically adjusting the slippage, a tradeoff between improved fuel economy vs. a satisfying driver experience can be realized.

  • Publication number: 20040092410
    Abstract: A high viscosity synthetic ester base stock of about ISO 68 to 400 is formed from a neopentylpolyol condensed with at least one monocarboxylic acid selected from the group consisting of linear acids having between 4 to 10 carbon atoms and branched chain acids having from 5 to 10 carbon atoms in an excess of hydroxyl to carboxylic acid groups to form a partial polyneopentylpolyol ester that is further reacted with the same or similar acid to form a high viscosity polyneopentylpolyol ester. Lubricants formed from the base stocks have satisfactory miscibility with standard highly or fully fluorinated refrigeration fluids.

  • Publication number: 20040092411
    Abstract: This invention generally relates to a high temperature stable polyol ester lubricant composition containing short chain carboxylic esters and a process for making the same. The polyol ester lubricant compositions are preferably formed from pentaerythritol and a mixture of C2 to C10 carboxylic acids in which (1) from 95 to 80 mole %, based on total acids, are C5 to C10 carboxylic acid, and (2) from 5 to 20 mole %, based on total acids, are at least one C2 to C4 carboxylic acid The polyol ester lubricant compositions of the present invention, specifically those using at least one C2 to C4 carboxylic acid, are useful as base stock for high temperature application such as Aviation Turbine Oils and exhibit enhanced anti-deposition and oxidation stability compared with the base polyol ester compositions while maintaining a good viscosity index.
