Abstract: A method, system, and computer program product for frame and frequency synchronization in packet-based Orthogonal Frequency Division Multiplexing (OFDM) in wireless digital communication systems. An OFDM packet includes a preamble preceded by a Cyclic Prefix (CP). The method includes computing a timing metric for packet-based OFDM. The timing metric yields a sharp peak at a preamble boundary. The preamble boundary is detected, based on a threshold. The threshold is determined a priori, based on mean and variance of the timing metric at the preamble boundary and in its neighborhood. The mean and the variance are evaluated for an Additive White Gaussian Noise (AWGN) channel. The detection of the preamble boundary enables frame synchronization in packet-based OFDM. The method further involves the task of frequency-offset estimation, using the preamble. The frequency-offset estimation enables frequency synchronization in packet-based OFDM.

Abstract: The present invention relates to a device and a method for utilizing a control module as an interfaced control of a dually configured AC/DC control coil comprising monitoring a coil voltage of the control coil, determining if the coil voltage is greater than a predetermined dropout voltage, and determining if the coil voltage is greater than a predetermined pickup voltage. Further, a generated astable pulse is reset in the event that the coil voltage is determined to be less than the predetermined dropout voltage.

Abstract: In one aspect, the present disclosure is directed toward a fastener tightening system. The system has a tightening tool configured to apply a torque to a fastener. Additionally, the system has a fastener data storage device located on the fastener and configured to store data related to the associated fastener. The system further has at least one component data storage device located on a component receiving the fastener to store data related to a tightening process. A data sensor is also included and is configured to sense data stored on the fastener data storage device and the at least one component data storage device. The system also has a controller configured to regulate operation of the tightening tool based on the sensed data and the sensed parameter.

Abstract: A method of cooling and lubricating an interface between a tool and a workpiece. A transiently stable emulsion is prepared including a water insoluble lubricant in water. The transiently stable emulsion, while stable, is introduced to the tool and/or the workpiece.

Abstract: A computationally efficient method and system for decoding shortened cyclic codes is presented. The increase in computational efficiency is achieved by improvement of the syndrome calculation step. Two embodiments of the present invention are described; the first embodiment is optimized for a hardware implementation and the second embodiment is optimized for a Digital Signal Processor (DSP) implementation. The present invention is applicable to decoding of all the binary shortened cyclic codes, including Fire codes used for Coding Scheme-1 (CS-1) for GSM.

Abstract: The invention provides a business method and a system to perform focused online shopping and sharing the online shopping experience with other users. The shopping-related information from various sources, and the search query, is converted into directed acyclic graph forests. These graphs are then compared to identify the search results that correspond to the shopping criteria. The sharing of online shopping experience includes sharing of search results between multiple users, discussing the search results through instant messaging (IM), revision of relevant items by any or all users and the flexibility of online-purchase by any user.

Abstract: A method in which a fluid is driven into a process unit through utilization of a propulsion unit operating in a process mode. A process is performed which utilizes the fluid in the process unit. The propulsion unit is set to operate in a recycle mode and fluid contaminated by the process is driven into a recycling unit through utilization of the propulsion unit. A system comprises a process unit that utilizes a liquid to perform a process. A recycling unit recycles fluid contaminated by the process. A propulsion unit coupled to the process unit and the recycling unit is adjustable between a process mode and a recycle mode.

Abstract: A system and method are provided for delivering financial services in a substantially automated and efficient manner. In one embodiment, an integrated Internet-based common digital platform automates and simplifies a mortgage closing process by receiving transaction information and merging the same with a set of electronic documents. The common digital platform then selectively permits users to access and edit certain ones of the documents, permits electronic signature of the documents, records transfers of negotiable instruments associated with the transaction, and stores the electronic documents in an electronic vault. The common digital platform also includes a dynamic pricing engine containing updated cost estimates for various closing cost elements in multiple geographical regions and generates closing cost estimates based on the geographical location of the real estate.

Abstract: A general purpose expert system architecture for diagnosing faults in any one of a plurality of machines includes a machine information database containing information on characteristics of various components of the machines to be diagnosed and a sensory input database which contains vibration data taken at predetermined locations on each of the machines. The system knowledge base contains a plurality of general rules that are applicable to each of the plurality of machines. The generality of diagnosis is accomplished by focusing on components that make up the machine rather than individual machines as a whole. The system architecture also permits diagnosis of machines based on other parameters such as amperage, torques, displacement and its derivatives, forces, pressures and temperatures. The system includes an inference engine which links the rules in a backward chaining structure.
