Abstract: Compact logic evaluation gates are built using null convention logic (NCL) circuits. The inputs to a null convention circuit include a NCL true input and a NCL complement input. The NCL circuit includes a gate coupled to the pair of inputs, where the gate comprises a plurality of transistors. The transistors allow for logical signal capture, provide a pair of cross-coupled inverters for data storage, and include a first and second pull-down device. The first pull-down device causes a first side of the pair of cross-coupled inverters to go to a “0” state when a “1” is applied to the NCL true input, and the second pull-down device causes a second side of the pair of cross-coupled inverters to go to a “0” state when a “1” is applied to the NCL complement input.

Abstract: The described embodiments present techniques for recovering from syntax errors. These techniques correct potential errors while preserving the shape of the parse tree, and the specific implementation of the techniques can be automatically generated from the grammar. These techniques may operate by looking back at states associated with previously-received tokens to determine pair matching status, when a synchronizing symbol is received. The techniques can respond to the pair matching status determination by potentially adding a synthesized token or by deleting a token that has already been received. The techniques may use a structure referred to herein as a tuple to assist with the evaluation of the pair matching status. Some of the techniques utilize indentation information to evaluate the pair matching status, while other techniques ignore such information. The described embodiments also include a technique for automatically generating the tuples from a set of grammar rules associated with the parser.

Abstract: A system, method, and computer program product are provided for performing a join operation between a local table at a local server and a remote table at a remote server. In accordance with an embodiment of the present invention, a query instruction to join the local table and the remote table is received at the remote server. Qualifying rows of the local table are then retrieved to the remote server, and the remote table is joined with the qualifying rows to generate a result table, which is then sent to the local server.

Abstract: Aspects of the subject disclosure may include, for example, a system that applies magnetic resonance elastography to a sample to obtain uncorrected k-space data where the magnetic resonance elastography utilizes a multi-shot spin-echo sequence with variable density spiral readout gradients, and adjusts the uncorrected k-space data to corrected k-space data by adjusting a k-space trajectory by shifting a center point for each shot to a new center point according to signal intensity and by adjusting a phase for each shot based on a phase offset that is determined according to the signal intensity. Other embodiments are disclosed.

Abstract: A filter for use within a baghouse for filtering particulate material from fluid flow. The filter is to be supported by a tubesheet of the baghouse. The filter includes an elongate bag that has an open end adapted to be disposed adjacent to the tubesheet and an encircling sidewall that extends from the open end to a distal end of the bag. The sidewall permits passage of fluid there through so that the fluid may pass through the bag and blocks passage of particulate material. The filter includes an elongate cage that is located within and supporting the bag and that has a variable effective length. The filter includes cage-associated structure for increasing the effective length of the cage to maintain the sidewall to be taut adjacent the cage. The cage may include structure inhibiting movement of the cage. The filter may be part of a baghouse assembly.

Abstract: A machine having an operator interface for requesting an action from an actuator of the machine includes a movable component of the operator interface. The movable component is movable among at least two positions. One of a magnet and a Hall effect sensor is positioned to move in response to movement of the movable component. The other of the magnet and the Hall effect sensor has a stationary position relative to the movable component. A pulse width modulator is operably coupled to the Hall effect sensor for producing a first pulse width modulated signal. The first pulse width modulated signal is altered in response to movement of one of the Hall effect sensor and the magnet relative to the other. An electronic controller is in communication with the pulse width modulator and the actuator and is configured to actuate the actuator in response to evaluation of the first pulse width modulated signal.
