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: A method for execution by a computing entity includes interpreting a fluid flow response from fluid flow sensors to produce a piston position of a piston associated with a head unit device. The head unit device includes a chamber filled with a shear thickening fluid (STF). The method further includes determining a door position based on the piston position. The method further includes determining parameters for wireless signals based on the door position. The method further includes facilitating utilization of the parameters for the wireless signals to promote successful communication of status and/or control of the door via the wireless signals.

Abstract: A mechanism is provided for automatically closing a file or a device. A service routine monitor monitors a request received from either an application that opened the file or a device driver that readied the device. The service routine monitor determines whether the file or the device has been accessed within a predetermined time interval. Responsive to the file or the device failing to be accessed within the predetermined time interval, the service routine monitor sends a call to the application that opened the file or the application or a higher level device driver that requested that the device driver ready the device. Responsive to a response from the application or the higher level device driver indicating that the use of the file or the device is no longer needed, the service routine monitor closes the file or quiesces the device.

Abstract: A bus interface for transfer of SONET/SDH data that supports a plurality of SONET/SDH flows. The invention supports two line coding schemes: 8B/10B encoding of STS-12, and SONET scrambled coding for STS-12, STS-48, and STS-51. The invention additionally supports two modes of line testing: entire links can be tested by inserting and checking PRBS sequences, and the SPE payload of the largest concatenated STS-Nc which the link can carry (STS-12c, STS-48c, STS-51c) can be individually tested by inserting and checking PRBS sequences.

Abstract: This invention provides a bus interface to connect SONET/SDH termination devices with payload processing devices while utilizing a minimum number of signals. The bus interface of this invention can scale with future advances in bandwidth in serial link technology.

Abstract: A method of interfacing between a non-continuous stream of cells of data and a continuous stream of frames of data, which includes transforming an incoming non-continuous cell stream into a continuous transmitted stream by inserting idle or non-assigned cells into the data stream during idle periods. The cells in the continuous stream are then mapped sequentially and contiguously onto the payload portions of frames. The frames are then transmitted synchronously.

Abstract: A method of detecting a pulse density violation in the T1 transmission of digital signals, which includes counting bits in sets of "k" successively in n serial stages generating an empty-out signal on detection of an "empty" set of "k" bits, and generating a pulse density violation on detecting a second set of "k" zero bits in the "n" stages of bits at a time when the empty-out signal is present.
