Abstract: The invention relates to modified Dda helicases which can be used to control the movement of polynucleotides and are particularly useful for sequencing polynucleotides.

Abstract: Techniques are disclosed for providing a navigation mode in electronic touch sensitive devices. The navigation mode can be used to advance forward and backward through displayed pages of content on a page-by-page or multi-page basis, such as pages of an eBook, photos, lists such as search results and files, or other consumable content that can be displayed in a page-like fashion. The user can engage the navigation mode with a particular gesture that includes a combination of contact points that uniquely and/or globally identify that the navigation mode is desired. The combination may include, for example, a press-and-hold activation contact point by one hand of the user, and one or more additional moving gesture contact points that indicate the desired navigation using the other hand of the user. Horizontal and/or vertical paging speeds correspond to the number of moving contact points, which can be effected with swiping or circular gestures.

Abstract: Techniques are disclosed for recording secure notes from the lock screen of a computing device. A note recording user interface may be accessed from the lock screen to allow a user to leave a note, such as a text, video, audio, or drawn note, or some combination thereof. The notes left using the note recording user interface may be saved such that only the intended recipient can access them, for example, after unlocking the computing device, thereby preventing others from seeing previously saved notes. The secure note system may include a retrieve notes function that allows users and/or recipients to retrieve the recorded notes directly from the lock screen of the computing device used to record them. The secure note system may also be configured to send notifications to inform the recipient when a secure note has been recorded (e.g., email or text message including copy of note).

Abstract: A method of operating a fuel injector including a piezoelectric actuator having a stack of piezoelectric elements, comprises applying a discharge current (IDISCHARGE) to the actuator for a discharge period so to discharge the stack from a first differential voltage level across the stack to a second, lower differential voltage level across the stack so as to initiate an injection event, and applying a charge current (ICHARGE) to the actuator for a charge period (T3 to T4?) so as to charge the stack from the second differential voltage level to a third differential voltage level so as to terminate the injection event. The method includes determining at least one engine parameter (e.g. common rail pressure) of the injection event prior to applying the charge current (ICHARGE) to the actuator and selecting the third differential voltage level in dependence on the at least one engine parameter.
