  • Patent number: 7424937
    Abstract: A first method for estimating a torque/force exerted by a load against an actuator driven by an electric motor against the load includes measuring motor current of the electric motor and measuring a position/angle or speed/angular speed of the actuator and includes calculating the torque/force exerted by the load against the actuator using at least a difference between a calculated motor torque/force and a calculated actuator-experienced torque/force. A second method includes measuring input voltage of the electric motor instead of measuring motor current. A third method includes measuring both motor current and input voltage. In one example, without limitation, the actuator is an automotive electromechanical brake caliper.

  • Patent number: 6869939
    Abstract: The present invention provides aqueous parenteral formulations containing an antiarrhythmic agent, such as amiodarone, and a sulfoalkyl ether cyclodextrin. The liquid formulations are clear, sterilizable, and chemically and physically stable. The liquid formulations do not require a surfactant and do not precipitate upon dilution with distilled water or other pharmaceutically acceptable liquid carrier. The sulfoalkyl ether cyclodextrin-containing formulation provides significant advantages over other cyclodextrin-containing formulations of amiodarone. The formulation can be prepared in acidic, neutral and slightly basic medium while providing acceptable concentrations of amiodarone suitable for parenteral administration. An SAE-CD-containing formulation of amiodarone can be provided in liquid form or as a reconstitutable powder. Moreover, highly concentrated solutions exceeding 200 mg of amiodarone per mL can be prepared.
