Abstract: Apparatuses and methods are provided for determining whether a user intends to provide an input using an image of a control appearing on a surface. An apparatus may include first and second cameras to capture set and second sets of two or more images of the surface, and a unit to determine whether various conditions are true. A first condition is that a particular number of skin-color pixels are present within one cell of the two or more images. A cell location substantially coincides with the image of the control. A second condition is that the skin-color pixels persist for at least a particular time period. A third condition is that a region of skin-color pixels has a substantially rectangular shape. A fourth condition is that corresponding edges of skin-color pixels in the first and second sets of images are within a predefined offset distance. Additional conditions are disclosed.

Abstract: Apparatus and methods for determining whether a user intends to provide an input using an image of a control appearing on a surface. An apparatus may include a first camera to capture two or more images of the surface, and a unit to determine whether various conditions are true. A first condition is that a particular number of pixels classified as skin color are present within one cell of the two or more images. A cell has a location substantially coinciding with the image of the control. A second condition is that the pixels classified as skin color persist for at least a particular time period. A third condition is that the pixels classified as skin color have a first shape. Additional conditions are disclosed. A signal indicative of an intent of a user to provide an input may be provided if the each of the first, second, and third conditions are true.

Abstract: Various embodiments are disclosed. A cooking vessel may include a cover, thermionic power converter, and a handle having a memory, a transmitter, and an IR light emitting diode. An infrared image sensor may be used with the IR light emitting to determine a location of the cooking vessel. A sensor and a transmitter may be disposed in the vessel cover to detect and transmit an indication of a boil condition. A system may include a sensor to detect a weight of a cooking vessel and a receiver to receive from the cooking vessel a memory-stored property of the cooking vessel, and a processing unit. The processing unit may determine a weight of the food and a predicted cooking time. The system may include a projected user interface and a proximity sensor. An apparatus may include an image sensor to capture a reference image and current images of a surface. A location of a cell on the surface may be determined from the images.

Abstract: This invention relates to methods and apparatus for detecting errors in transmitted data. In one embodiment, a method includes the steps of transmitting data, accumulating a transmit sum, receiving the data, accumulating a receive sum, comparing the transmit and receive sums; and evaluating the result of the comparison for determining a transmission accuracy metric.

Abstract: A graphics controller including a display pipe and a first-in-first-out (FIFO) buffer within the display pipe is provided. The FIFO buffer stores pixel data representing an image for display. The pixel data includes a pixel value and a corresponding repeater value. The repeater value indicates the number of times the pixel value is successively repeated within the image. The selection logic counts a number of times a pixel value is output and is configured to pause fetching of a next pixel value from the FIFO buffer until the pixel value has been output as many times as indicated by the repeater value.
