Know the correct timing characteristics associated with successive fingerprint readings; 3.) Be able to successfully “hack” the authentication server in order to gain access to minutia or image information, and finger sequence information, and timing information, which would be required in order to fully compromise the authentication system. The technique embodied by the invention represents an overlay of a known, ordered sequence, which may or may not be timed, over the fingerprint authentication process itself.

Systems and methods are provided in which optimized driving trip schedules are generated, optimized, optionally scored according to multiple criteria including fatigue, and provided to a driver or other personnel. Trip schedules are generated from route plans connecting start and end waypoints and optionally intermediate waypoints. Hours-of-service (HoS) regulations and business objectives (fuel efficiency, time-constrained waypoints, etc.) are considered, where a forward greedy algorithm may be used to solve the problem of on-time delivery under such constraints. Driver sleep and fatigue are then determined from the generated trip schedules using sleep prediction models and fatigue prediction models. Trip schedules may then be scored, modified, and optimized in accordance with several other constraints.

The principles of the present invention provide for providing contention free quality of service to wireless stations. A station indicates to an access point that higher priority data (e.g., time constrained data) is to be sent to the access point. The access point receives the indication and selects a slot time for the station based on the number of other stations that have also indicated higher priority data. A slot time is selected such that the station can check for access to a common wireless link before any stations with lower priority data (e.g., data without time constraints). The access point sends the selected slot time to the station and the station receives the slot time. When the station receives an indication that an application has higher priority data to send, the station checks the common wireless link for availability at the selected slot time.

The invention provides a modulation method based on an elliptically spherical function. With the design of the multiplexing time-domain orthogonal base band modulation waveform, a multiplexing base band premodulation is carried out. Signals after the base band premodulation at each branch are superimposed and synthesized in a time domain to form a path of signals, and then sine-wave carrier modulation is carried out to move the frequency spectrum of the signal to radiation frequency band and then the frequency spectrum is output. The waveform of the base band modulation adopts the elliptically spherical function with limited time-domain duration time and approximately finite frequency band. The frequency band of a communication system can rapidly approach to the Nyquist rate with the increase in the number of the time-domain orthogonal base band modulation waveform. Simultaneously, the system has better power utilization rate and is convenient and easy to realize.

In addition, a sender or system administrator may grant preferred end-users pre-release authority to replicate the sender's original content within the server so that it may later be compared against the sender's original content sent to a website display or gallery.

When an IC layout is to include time-constrained signal paths, a placement plan defining positions of cells forming the IC is analyzed to estimate lengths of nets needed to interconnect the cells based on the positions of cells included in those signal paths. A capacitance and resistance of each net is then estimated based on its estimated length. The delay through each time-constrained signal path is then estimated based on the estimated capacitance and resistance of each net to be included in the time-constrained signal path and on the terminal impedances, switching speeds and driving strengths of the cells included in the signal path. The estimated path delay for each signal path is then compared to its timing constraint to determine whether that signal path is a “critical signal path” likely to fail to meet its timing constraint following development of a detailed routing plan. A non-linear programming technique is then employed to determine how, with minimal disturbance to the placement plan, to reposition cells forming the critical paths so that when the nets are routed between the cells, all critical paths will be more likely to satisfy their timing constraints.

The invention provides a multi-underwater robot communication-oriented energy-saving routing method. The method comprises three main links of route searching, route restoring and route maintenance and particular comprises the following steps of: judging whether routing exists between two robot nodes or not; if yes, judging whether a broken link exists in the routing or not, and otherwise, selecting and searching the routing between the two robots by a link life time limit-based route searching algorithm; if the broken link exists in a network, performing route restoring by an energy-saving route restoring algorithm; if the broken link does not exist in the network, detecting whether better routing exists or not by an algorithm, if yes, updating the current routing by an energy-saving route maintenance algorithm, and otherwise, judging whether a task ends up or not; and if the task ends up, finishing the process. The multi-underwater robot communication-oriented energy-saving routing method is applied to a multi-underwater robot system. The multi-underwater robot communication-oriented energy-saving routing method has the advantages of taking energy of communication into direct consideration in the steps of route researching, route restoring and route maintenance, greatly saving the energy and the response time of underwater robot communication and guaranteeing that the underwater robot task can be performed successfully.

Method for correcting seismic simulations, RTM, and FWI for temporal dispersion due to temporal finite difference methods in which time derivatives are approximated to a specified order of approximation. Computer-simulated seismic data (51) are transformed from time domain to frequency domain (52), and then resampled using a mapping relationship that maps, in the frequency domain, to a frequency at which the time derivative exhibits no temporal dispersion (53), or to a frequency at which the time derivative exhibits a specified different order of temporal dispersion. Alternatively, measured seismic data from a field survey (61) may have temporal dispersion of a given order introduced, by a similar technique, to match the order of approximation used to generate simulated data which are to be compared to the measured data.

A video compression process speeds the optimal choice of quantizers for compressing a data stream by setting up the optimization problem as a path-optimization problem in configuration space and finding the lowest cost path through the configuration space. The process begins with a starting node (or “state”) and propagates least-cost waves through the space until a path is completed to the end. The process may continue using uncompleted paths while their costs are less than the end state, beginning with the lowest cost incomplete path, until an improved path is found. The process may further continue, for a time constrained process, until time runs out or all useful possibilities are exhausted.
