Abstract: Methods, articles, and devices for evaluating the contribution of a food item(s), recipe(s), and meal plan to nutritional requirements are disclosed. Nutritional criteria for a person, which may be based upon general or specific dietary recommendations or customized for a particular individual's dietary needs, include reference value(s) or ranges for each of a plurality of nutrients, including vitamins, minerals, or food groups with a common profile. Indicia of satisfying the person's nutritional criteria are generated for a given food item, recipe, or meal plan provided to or selected by the user. The indicia include a plurality of bars arranged along a circumference of a circle, the length, direction and other aspects of each bar corresponding to the extent to which the one food item, recipe, or meal plan meets a nutritional criterion's reference value.

Abstract: A Bluetooth filter driver sends non-native, Bluetooth configuration data via a USB port to a Bluetooth controller by commanding a Bluetooth USB driver to change the state of the USB port to a power-up state in a Bluetooth-enabled, wireless mobile device.

Abstract: Methods and systems are provided for automatically calibrating a pointing device, such as a stylus, with a writing surface, such as a touch screen. In one example, an automated method is implemented to calibrate the writing surface based user inputs attempting to use the computer for functions other than calibration of the writing surface. The user inputs may be, for example, a user selecting a button within a non-calibration software application. The automated method may generate a miscalibration vector based upon where the user input was received and where the user input was expected. In yet another example, a bias field may be generated for the writing surface from the collected user inputs. In yet other examples, a computing device may comprise computer-executable instructions for performing one or methods of calibrating the writing surface.

Abstract: A tablet PC having an interactive display, which is touchscreen enabled, may be enhanced to provide a user with superior usability and efficiency. A touchscreen device may be configured to receive multiple concurrent touchscreen contacts. The attributes of the multiple concurrent touchscreen contracts may be mapped to operations performed on the computing device. As a result, a user can trigger the execution of the toggle accessibility aid operation and the screen rotation operation with greater convenience. Moreover, the tablet PC may be configured to map an operation to a hand gesture or input.

Abstract: Systems and methods are provided for controlling the appearance of application windows on a computer display screen. A user identifies either an application window currently running on the computer or a new application to be started. The user also identifies a size, shape, and screen location by inputting a geometric shape, such as by drawing a rectangle with a pen or stylus input device, on the display screen. The appearance of the application window is set based on the geometric shape. The application window is resized and moved, for a currently running application, or created, for a new application, on the display screen.

Abstract: A system for enabling a tablet input object is described. A tablet input object can take various inputs from touch, a mouse, and a pen and send their information to an application.

Abstract: Systems, methods, and computer-readable media process and distinguish user input device gestures, such as gestures input via a pen in a pen-based computing system, e.g., to quickly and reliably distinguish between electronic ink entry, single taps, double taps, press-and-hold actions, dragging operations, and the like. Systems, methods, and computer-readable media also are provided for dynamically calibrating a computer system, e.g., calibrating a displayed input panel view based on input data recognized and received by a digitizer. Such systems and methods may operate without entering a dedicated or special calibration application, program, or routine.
