Abstract: A computer-implemented method, computer program product and system for password verification are provided. A preset password and at least one condition for applying the preset password is received from device of a user. It is then determined whether the preset password is eligible. Responsive to the preset password being eligible, the preset password is registered. An input password from a device of a vendor can, therefore, be verified based on the registered preset password.

Abstract: Methods, systems, and devices for determining a person's location and for presenting navigation instructions are provided. In an embodiment, a method for determining a user's location includes obtaining an image of a graphical indicator at a first location. The graphical indicator is located on a surface of an object in an area and the graphical indicator includes mapping and location information encoded in the graphical indicator. The method also includes determining a map and a user's location on the map according to the graphical indicator.

Abstract: A computer-implemented method includes detecting that a first script has been modified to an updated script and that the first script is currently running. A data key point is selected from among a set of data key points available in the first script. At the selected data key point in the first script, a current state of the first script is saved in a storage object external from the first script, responsive to detecting that the first script has been modified. An execution point is selected in the updated script. The current state of the first script is loaded into the updated script. The updated script is run from the execution point, with the current state of the first script.

Abstract: A method and system for determining causes. The method includes generating a set of cause indices. Each cause index includes a cause, at least one pattern, and a probability of the cause for the pattern. The method also includes receiving a data set, and determining that one or more indexed patterns match a pattern in the data set. Further, the method includes retrieving causes for the indexed patterns that match the pattern in the data set, as well as determining probabilities of the retrieved causes for the pattern in the data set.

Abstract: A noise source emits an acoustic noise wave with a noise frequency corresponding to an attribute of a control-status signal associated with the noise source. A method to reduce the noise comprises generating, based on the noise frequency corresponding to the attribute, an anti-noise signal having the noise frequency. The method further comprises phase-shifting the anti-noise signal to output a phase-shifted anti-noise signal that can be used to generate a noise-cancelling acoustic wave. The method can include aligning the first anti-noise signal to be in-phase with the acoustic noise wave. An anti-noise apparatus to implement the method includes an anti-noise generator, to generate the anti-noise signal, and a phase shifter to generate and output the phase-shifted anti-noise signal. The anti-noise apparatus can include a phase detector and phase alignment element to align the anti-noise signal to be in-phase with the acoustic noise wave.
