Abstract: A power coupler for transferring rotary power from a rotary power device to a load device includes a shear thickening fluid (STF) and a chamber that contains the STF. The power coupler further includes a drive shaft housed radially within a drive side section of the chamber and protruding outward from an end of the chamber for coupling to the rotary power device. The power coupler further includes a load shaft housed radially within a load side section of the chamber and protruding outward from another end of the chamber for coupling to the load device. The power coupler further includes a drive turbine housed radially within the drive side section and coupled to the drive shaft. The power coupler further includes a load turbine housed radially within the load side section at a fixed operational distance from the drive turbine and coupled to the load shaft.

Abstract: A head unit system for controlling motion of an object includes a secondary object sensor, shear thickening fluid (STF), and a chamber configured to contain a portion of the STF. The chamber further includes a front channel and a back channel. The head unit system further includes a piston housed at least partially radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second piston bypasses to control flow of the STF between opposite sides of the piston. The chamber further includes a set of fluid manipulation emitters to control the flow of the STF to cause selection of one of a variety of shear rates for the STF within the chamber.

Abstract: The instant disclosure provides antibodies that specifically bind to CTLA-4 (e.g., human CTLA-4) and antagonize CTLA-4 function. Also provided are pharmaceutical compositions comprising these antibodies, nucleic acids encoding these antibodies, expression vectors and host cells for making these antibodies, and methods of treating a subject using these antibodies.

Abstract: A method of determining the time delay between echoes of an ultrasound pulse emitted by an ultrasound inspection device into an object, the method including: with the ultrasound probe in engagement with a front-wall feature of the object such that the ultrasound inspection device's ultrasound axis is arranged at an angle relative to the nominal surface normal of the front-wall feature, taking an ultrasound measurement which includes the ultrasound inspection device emitting an ultrasound pulse and recording echoes thereof; and determining the time delay between echoes of the pulse via a time delay determination process which adjusts the time delay calculation based on the angle of the ultrasound inspection device's ultrasound axis with respect to the nominal surface normal of the front-wall feature.

Abstract: A method of determining the time delay between echoes of an ultrasound pulse emitted by an ultrasound inspection device into an object, the method including: with the ultrasound inspection device in engagement with a front-wall feature of an object at a point to be measured, taking an ultrasound measurement, which includes the ultrasound inspection device emitting an ultrasound pulse and recording an ultrasound measurement signal including a front-wall echo and at least one interface echo reflected by an internal or back-wall feature of the object; and determining the time delay between the front-wall echo and the at least one interface echo via autocorrelation of at least a segment of the ultrasound measurement signal which comprises the front-wall echo and the at least one interface echo.

Abstract: An apparatus for crushing sugar cane to extract the juice has opposed crushing rolls at least one of which is formed with juice channels which are temporarily plugged by bagasse after the juice has entered into the channel. Further rotation of the rolls removes the trapped juice away from the cane blanket and the bagasse plug is then scraped out of the top of the channel to allow the juice to drain. The juice is drained away from the cane blanket and is not reabsorbed thereby. Efficiency of juice removal is improved. Further efficiency improvements are obtained by having pairs of crushing rolls positioned above each other such that the cane blanket moves in a generally vertical direction.
