| 20100149121 | SYSTEM AND METHOD FOR INTERFACING APPLICATIONS PROCESSOR TO TOUCHSCREEN DISPLAY FOR REDUCED DATA TRANSFER - System and method for substantially reducing an involvement of an applications processor in receiving data from a touchscreen display. In one aspect, the system includes a controller may be configured in an autonomous mode where it automatically measures the touchscreen display based configuration information received from the applications processor, determines notable events based on the measurement data, stores data and event identifiers related to the notable events in a memory, and sends a notification to the applications processor when event data is available In another aspect, the system includes a controller that filters user interactions events and transmits data related to only notable events to the applications processor. Because of the autonomous and event filtering operations of the touchscreen controller, there are substantially less communications between the controller and the applications processor. This improves the speed and efficiency of the applications processor. | 06-17-2010 |

| 20090149267 | Golf club grip alignment using laser aligning device - A laser aligning device is mounted on the flat side of a putter grip or other cylindrically asymmetric surface of a club grip and emits a fan shaped light sheet. The light sheet is perpendicular to the flat side of the putter grip. The light sheet projects a visible laser line on a plane such as the ground when the head is on the same plane. The alignment of the grip relative to the putter head's face can be inspected by visually inspecting the orientation of the projected line on the plane relative to the head's face. The grip can be adjusted and fixed so that it is properly oriented to the face. | 06-11-2009 |
