  • Signal correcting method and signal correcting device
    Patent number: 9524692
    Abstract: A signal correcting method and a signal correcting device. The signal correcting method includes sampling a signal to be corrected at different sampling times, and comparing a signal value at each of the sampling times in one signal period with a preset signal value corresponding to the sampling time. When the signal value at the sampling time is equal to the corresponding preset signal value, the signal value at the sampling time is kept unchanged. When the signal value at the sampling time is not equal to the corresponding preset signal value, the signal value at the sampling time is corrected to be the preset signal value corresponding to the sampling time.

  • Pictorial methods for application selection and activation
    Patent number: 9501694
    Abstract: Methods and devices provide a quick and intuitive method to launch a specific application, dial a number or send a message by drawing a pictorial key, symbol or shape on a computing device touchscreen, touchpad or other touchsurface. A shape drawn on a touchsurface is compared to one or more code shapes stored in memory to determine if there is a match or correlation. If the entered shape correlates to a stored code shape, an application, file, function or keystroke sequence linked to the correlated code shape is implemented. The methods also enable communication involving sending a shape or parameters defining a shape from one computing device to another where the shape is compared to code shapes in memory of the receiving computing device. If the received shape correlates to a stored code shape, an application, file, function or keystroke sequence linked to the correlated code shape is implemented.
