Abstract: One example of a device includes a sensor, a memristor code comparator, and a controller. The sensor is to provide a sensor signal. The memristor code comparator is to compare the sensor signal to a reference signal. The controller is to determine a status of the sensor signal based on the comparison.

Abstract: A hand-held device and method for operating a single pointer touch sensitive user interface of a hand-held electronic device are provided. The method includes defining as being active a first one of a set of two or more controllable interface functions including at least a first controllable interface function and a second controllable interface function. A control gesture is then detected and the control gesture is associated with the active one of the set of two or more controllable interface functions, where the detected pattern adjusts the performance of the active controllable interface function. A transition gesture is then detected including a pointer pattern movement, which is not included as a control gesture for any of the two or more controllable interface functions, where upon detection of the transition gesture, the transition gesture defines a second one of the set of two or more controllable interface functions as being the active one of the set of two or more controllable interface functions.

Abstract: The present invention provides a hand-held device including a split touch sensitive input surface, the touch sensitive input surface including a first touch sensitive array, which has a position sensor adapted for detecting a relative position of a first pointer device, and a second touch sensitive array which has a position sensor adapted for detecting a relative position of a second pointer device. The second touch sensitive array is separate from the first touch sensitive array and is located on a common side with the first touch sensitive array.

Abstract: A display interface and method for presenting visual feedback of a user interaction with an image being presented via an electronic device are provided. The display interface includes a display adapted for visually presenting to the user at least a portion of an image. The display interface further includes a user input adapted for receiving a gesture including a user interaction with the electronic device. The display interface still further includes a controller. The controller is adapted for associating the gesture with a function, determining whether the associated function has reached a limit which would preclude execution of the associated function, and executing the function associated with the detected gesture. If the associated function has not reached the limit which would preclude execution of the associated function, then controller is adapted for executing the function associated with the detected gesture.

Abstract: A method for enabling asset tracking that includes the steps of: receiving (910) a first excitation signal at a first power level using a first frequency band; and (920) upon determining that a first set of parameters is satisfied, awakening from an inactive mode to an active mode, transmitting data at a second power level that is greater than the first power level using a second frequency band that is different from the first frequency band, and returning to the inactive mode, wherein determining that the first set of parameters is satisfied comprises at least determining that the first excitation signal corresponds to a first wake-up circuit.
