Abstract:
Embodiments enable a mobile device to execute an action analogous to a user-defined action in response to receipt of a gesture analogous to a user-defined gesture. In a first embodiment, a computer-implemented method executes an action on a mobile device. A lock screen view is displayed on the mobile device to prevent unauthorized and inadvertent access to the mobile device's data. While the mobile device is locked, a touch gesture having a pre-defined shape is detected on a touch screen of the mobile device independently of the initial position of the touch gesture on the touch screen. In response to detection of the touch gesture, a particular action is executed on the mobile device while the mobile device stays locked. The particular action determined according to the pre-defined shape. In this way, detection of the touch gesture causes the particular action to execute while keeping the mobile device locked.
Abstract:
A photoionization detector includes a housing, electrical contacts within the housing and an easily removable and replaceable photoionization chamber within the housing. The photoionization chamber includes a cathodic electrode and an anodic electrode which may be coated with a thin layer of material. The photoionization chamber and the associated cathodic electrode and anodic electrode are removable from within the housing as a unit. The photoionization chamber makes electrical connection with the contacts when seated within the housing regardless of the orientation of the photoionization chamber about an axis.
Abstract:
Embodiments enable a mobile device to execute an action analogous to a user-defined action in response to receipt of a gesture analogous to a user-defined gesture. In an embodiment, a method automatically interprets touch gestures on a mobile device. In the method, a user input is received that defines a first touch gesture to initiate a first action on an application of the mobile device. A second touch gesture is received on a touch screen of the mobile device. The second touch gesture is similar, but not identical, to the first touch gesture, and has a different orientation, size or position from the first touch gesture. In response to receipt of the second touch gesture, a second action is determined on the application of the mobile device according to a difference between the first and second touch gestures in orientation, size or position on the screen of the mobile device. Finally, the second action is initiated.
