    Abstract: A system comprises magnetorheological fluid clutch apparatuses, each magnetorheological fluid clutch apparatus including a first rotor having at least one first shear surface, a second rotor rotating about a common axis with the first rotor, the second rotor having at least one second shear surface opposite the at least one first shear surface, the shear surfaces separated by at least one annular space, magnetorheological (MR) fluid in an MR fluid chamber including the at least one annular space, the MR fluid configured to generate a variable amount of torque transmission between the rotors when subjected to a magnetic field, and coil(s) actuatable to deliver a magnetic field through the MR fluid such that each said magnetorheological fluid clutch apparatus is actuatable to selectively transmit actuation by controlled slippage of the rotors with respect to one another. The MR fluid chambers of the second magnetorheological fluid clutch apparatuses are in fluid communication for the MR fluid to circulate between the magnetorheological fluid clutch apparatuses.

    Abstract: A telepresence controller is provided for interaction with a remote telepresence session to control haptic interactions between an end effector and the remote telepresence session. Force sensor(s) monitor force(s) applied to an end effector. Position sensor(s) monitor a position of the end effector. The telepresence controller communicates with the remote telepresence session to exchange position data and force data indicative of concurrent haptic movements of the end effector and an object in the remote telepresence session. Magnetorheological fluid clutch apparatus(es) have an input adapted to be connected to a power source and configured to receive a degree of actuation (DOA) therefrom, the magnetorheological fluid clutch apparatus(es) having an output being actuatable to selectively transmit the received DOA to the end effector by controlled slippage. A force controller module determines a force input required on the end effector as a function of haptic events for the object in the remote telepresence session. A clutch driver module drives the magnetorheological fluid clutch apparatus with the controlled slippage being as a function of the force input.

    Abstract: A braking control apparatus comprises at least one torque source. At least one magnetorheological (MR) fluid clutch apparatus having an input coupled to the at least one torque source to receive torque from the torque source, the MR fluid clutch apparatus controllable to transmit a variable amount of torque via an output thereof. A modulation interface couples the output of the at least one MR fluid clutch apparatus to a braking power transmission of a brake system. At least one sensor provides information indicative of a braking state of the load. A processing unit receives the information indicative of the braking state of the load and for outputting a signal to control the at least one MR fluid clutch apparatus in exerting a desired force on the braking power transmission to assist in braking the load. A method for assisting a manually-actuated braking of a vehicle is also provided.

    Abstract: An active suspension system comprises at least one biasing device configured to support a body from a structure, and at least one motor. A magnetorheological (MR) fluid clutch apparatus(es) is coupled to the at least one motor to receive torque from the motor, the MR fluid clutch apparatus controllable to transmit a variable amount of torque. A mechanism is between the at least one MR fluid clutch apparatus and the body to convert the torque received from the at least one MR fluid clutch apparatus into a force on the body. Sensor(s) provide information indicative of a state of the body or structure. A controller receives the information indicative of the state of the body or structure and for outputting a signal to control the at least one MR fluid clutch apparatus in exerting a desired force on the body to control movement of the body according to a desired movement behavior.
