An improved system and method of fairly and securely enabling timed-constrained competitions over the Internet among millions of competitors while compensating for the variable network communication latencies experienced by client machines used by the competitors. The system employs globally time-synchronized Internet information servers and client machines in order to synchronize the initial display of each invitation to respond (e.g. stock price to buy or sell, query to answer, or problem to solve) on a client machine so each competitor can respond to the invitation at substantially the same time, regardless of his or her location on the planet, or the type of Internet-connection used by his or her client machine. Also, by using globally time-synchronized client machines, each competitor's response is securely time and space stamped at the client machine to ensure that competitor responses are resolved within microsecond accuracy.

An ultra-wide band (UWB) waveform generator and encoder for use in a UWB digital communication system. The UWB waveform is made up of a sequence of shaped wavelets. The waveform generator produces multi-amplitude, multi-phase wavelets that are time-constrained, zero mean, and can be orthogonal in phase, yet still have a −10 dB power spectral bandwidth that is larger than the frequency of the peak of the power spectrum In one embodiment, the wavelets are bi-phase wavelets. The encoder multiplies each data bit by an n-bit identifying code, (e.g., a user code), resulting in a group of wavelets corresponding to each data bit. The identifying codeword is passed onto the UWB waveform generator for generation of a UWB waveform that can be transmitted via an antenna.

The invention, which is an embodiment of what the inventor calls, “Active behavior Fingerprint Authentication” is one which employs a sequential reading of fingerprints of various fingers, in a way that may or may not be time constrained, as a means to improve authentication security. Authentication security is strengthened based upon the reduced likelihood that a potential intruder would 1.) Know what the correct sequence of fingerprints were associated with the control authentication template; 2.) 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.

A mobile device (10) manages tasks (18) using a scheduler (20) for scheduling tasks on multiple processors (12). To conserve energy, the set of tasks to be scheduled are divided into two (or more) subsets, which are scheduled according to different procedures. In a specific embodiment, the first subset contains tasks with the highest energy consumption deviation based on the processor that executes the task. This subset is scheduled according to a power-aware procedure for scheduling tasks primarily based on energy consumption criteria. If there is no failure, the second subset is scheduled according to a real-time constrained procedure that schedules tasks primarily based on the deadlines associated with the various tasks in the second subset. If there is a failure in either procedure, one or more tasks with the lowest energy consumption deviation are moved from the first subset to the second subset and the scheduling is repeated.

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.

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.
