Provided is a battery charger. The battery charger comprises a power converter, an input power connector, and an output power connector. The input power connector is configured to be connected to a power source such that the input power connector is arranged between the power converter and the power source. The output power connector is configured to be connected to an electronic device such that the output power connector is arranged between the power converter and the electronic device. The battery charger further includes a power control relay configured to connect the power converter to the input power connector. The battery charger further includes a timer device configured to disconnect the power converter from the input power connector after a predetermined amount of time has elapsed.

Aspects of the present invention disclose a method for securely storing data. The method includes one or more computer processors receiving, by one or more computer processors, a request to store data, wherein the data includes a plurality of elements. The method further includes generating a plurality of elements of encoded data by on applying one or more encoding algorithms to the data, wherein a quantity of the plurality of elements of the encoded data is equal to a quantity of the plurality of elements of the data. The method further includes distributing the plurality of elements of the encoded data into two or more subsets of the encoded data, without duplication. The method further includes transmitting the two or more subsets of the encoded data to a corresponding quantity of two or more storage systems.

A method and Web server for verifying a Web service request originating from a Web page is provided. The method includes matching the Web service request with a Web service. A sequence ID contained in the request is identified. The Web service request is verified if the identified sequence ID does not correspond with a previous sequence ID for the matched Web service. Additionally, the Web service does not verify a same Web service request twice.

Embodiments of the present invention provide systems and methods for controlling a mobile device of interest. In order to automatically turn or keep the ringer off for the mobile device of interest, the number of other mobile devices within a defined proximity and maintaining a minimum time threshold in the presence of the other mobile devices within the defined proximity are evaluated. Upon determining there is at least a minimum number of other mobile devices within the defined proximity and the mobile device of interest maintains the minimum time threshold in the presence of the other mobile devices within the defined proximity, the mobile device of interest automatically turns the ringer off.

Embodiments of the present invention provide a method, computer program product, and system for a uni-directional and multi-directional interchangeable screen. The system includes a screen and an opaque micro-tube connected at one end to the screen. A bottom backlight is connected to the other end of the opaque micro-tube and a top backlight is connected to the screen. The system is controlled by an automated screen selection program, which activates the bottom backlight and deactivates the top backlight for uni-directional screen view. Automated screen selection program activates top backlight for multi-directional screen view.

A method and associated device for moving an image displayed on a touchscreen of the device. It is determined that an object previously moving on the touchscreen toward a first outer edge of the touchscreen has traversed the first outer edge in a first direction perpendicular to the first outer edge so as to no longer be touching the touchscreen. The displayed image had moved in the first direction toward the first outer edge in synchronization with the previous movement of the object toward the first outer edge. In response to the object having traversed the first outer edge, one or more motion sensors are activated to monitor the object for continuing movement of the object. The one or more motion sensors ascertain the continuing movement of the object away from the first outer edge, and in response, the displayed image is moved toward the first outer edge.

A navigation system which includes a central processing unit; a nonvolatile storage for storing digitized map data; a road sinuosity S(R) of a route including a plurality of digitized road segments calculated from a starting point to a destination point to be traveled by a user by summing the rotation angle of each of the road segments divided by the distance of each of the road segments; a module to determine an estimated travel time of the route; a module to determine a corrected travel time using the road sinuosity S(R); and a display to display the corrected travel time.

A method and system for verification of a pattern based passcode. User input of a series of key inputs to a keyboard is received from a user. A registered pattern for the user of a sequence of keyboard direction movements is retrieved, wherein the pattern based passcode is the registered pattern. A first character in a first key input of the series of key inputs is identified, wherein the first key input is the first key, of the series of key inputs, that was inputted by the user. It is determined is made that that the identified first character is not in an excluded group of characters and in response, it is verified that a pattern of directional movements from the first character to the remaining characters after the first character in the series of key inputs matches the registered pattern for the user.

A method and associated device for moving an image of displayable content displayed on a touchscreen of the device. Movement of an object along the touchscreen of the device toward an outer edge of the touchscreen is detected, and in response, the displayed image is moved toward the outer edge in synchronization with the detected movement of the object. It is determined that the object has traversed the outer edge of the touchscreen so as to no longer be touching the touchscreen, and in response, one or more motion sensors are activated to monitor the object for continuing movement of the object. The one or more motion sensors ascertain the continuing movement of the object away from the outer edge, and in response, the displayed image is moved toward the outer edge in synchronization with the ascertained continuing movement of the object.

A method and system for verification of a pattern based passcode. A user input of a series of key inputs is received. A registered pattern for the user of a sequence of keyboard direction movements is retrieved. A first character input in the series of key inputs is identified. It is determined that the identified first character is not in an excluded group of characters, wherein the excluded group of characters are previously used first characters in a defined period or number of instances for the user. In response to having determined that the first character is not in the excluded group of characters, the series of key inputs after the first character input is compared with the registered pattern for the user.

This invention relates to a method, system and computer program product for selecting an optimized solution in a computerised multiple-constraint problem space, comprising: receiving a linear function for optimization; receiving a set of constraints for the linear function; determining a first optimal solution for the linear function and initial constraints using linear programming solver; creating a new set of constrains using the first optimal solution as a constraint in addition to the initial constraints; creating a new quadratic function by adding a quadratic objective of slack variables to the linear function; and determining a solution to the quadratic function and new constraints using a quadratic programming solver.
