Abstract: A head unit device for controlling motion of an object includes a chamber filled with a shear thickening fluid (STF) and a piston. The piston is housed within the chamber and exerts pressure against the STF from a force applied to the piston from the object. The STF is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates. The piston includes at least one piston bypass between opposite sides of the piston that controls flow of the STF between the opposite sides of the piston to selectively react with a shear threshold effect of the first range of shear rates or the second range of shear rates.

Abstract: As banking transactions are processed by a bank teller, all of the relevant information with respect to the transaction (e.g., dollar amount) is captured in an electronic file. Each of the electronic files from the various branches of the bank are forwarded to a central back office processing center where the electronic files are combined into a single Transaction Repository. At the end of the branch day, all of the paper associated with the transactions is forwarded from the branches to the back office processing center. The paper transactions are imaged in the conventional manner and the Magnetic Ink Character Recognition (MICR) data is read from the paper. The present invention then automatically correlates the images and MICR data captured from the paper with the complete transaction record contained in the Transaction Repository. Most of the conventional back office processing can now be performed without the need to perform character recognition and without the need for excess human intervention.
