Abstract: An LED light source module is disclosed, which can replace a halogen bulb. The LED light source module includes an LED light source, a heat sink, an electric fan unit, a driver circuit, and an attachment, and all of these constituent elements are integrated. A structure of the attachment is the same as that of an attachment of a halogen bulb generally used as a light source of a lighting apparatus for a vehicle. The LED light source module can replace a halogen bulb. When the LED light source module needs replacement, unlike the conventional LED head light where the whole lamp main body is replaced, only the LED light source module can be replaced.

Abstract: A navigation device with dual airflow sensors. The navigation device includes a first sensor to detect a first airflow in response to movement of the navigation device in approximately a first direction. The navigation device includes a second sensor to detect a second airflow in response to movement of the navigation device in approximately a second direction. The navigation device also includes first and second airflow directors which are aligned with the first and second sensors, respectively. Each airflow director includes multiple openings to direct the first and second airflows across the first and second sensors, and to maintain the first and second airflows substantially independent of one another. The navigation device also includes a microcontroller to generate a two dimensional navigation signal based on input signals from the first and second sensors.

Abstract: Advantage is taken of the fact that as a player tires, the high frequency components of the player's movement typically decreases in comparison with the low frequency components of the player's movement. By analyzing the frequency components of the player's motion, as obtained from signals generated by the motion input device, the system is able to determine changes in a player's response level and change the game accordingly. In one embodiment, wavelet analysis of an input device signal is used to control or adjust a program.

Abstract: A system and method for tracking the x, y and z coordinates of a position of an input device in an interactive computer system is disclosed. An image sensor situated on the input device captures images of an electronic marker displayed on a display screen. As the position of the input device changes, the features of the electronic marker as captured by the image sensor also change. Images of the electronic marker captured during game play are compared to a calibration image of the electronic marker to determine current x, y and z coordinates of positions of the input device. The game display is updated to reflect the movements of the input device.

Abstract: Images are constructed by compositing a plurality of sequential images. The sequential images are obtained by moving the image capture device and storing the positional attribute data (focal attributes) in association with each captured image. For example, wide-angle views, 3D views and/or video views of a subject can be constructed by compositing a plurality of sequential images.

Abstract: A system and method for performing an optical tracking operation computes a translated movement value of a displacement values using a relationship between a reference displacement value derived using a reference surface and a corresponding displacement value using a target surface. The displacement value is produced using image correlation by optically sensing the target surface. The translated movement value is used for the optical tracking operation.

Abstract: A system and method for performing optical navigation addresses M×N photosensitive elements of an image sensor array to capture first frames of image data of a navigation surface when set to a first operational mode such that each of the first frames of image data includes M×N sampled signals, and addresses at most the M×N photosensitive elements of the image sensor array to capture second frames of image data of the navigation surface when set to a second operational mode such that each of said second frames of image data includes less than M×N sampled signals.

Abstract: A pointing device includes a light source, an aperture member, and a detector. The light source provides incident light for illuminating an obverse surface of a plate at a predetermined incident angle. The plate has the obverse surface and a reverse surface and is transparent to the wavelength of the incident light. The aperture member has an opening through which speckle light from the obverse surface and speckle light from the reverse surface pass. The speckle light results from the incident light. The detector detects the intensity of the speckle light passing through the opening. In order that the speckle light from the obverse surface and the speckle light from the reverse surface overlap each other at the detector, the opening has a longitudinal dimension in a direction in which the incident angle is formed.
