摘要:
A scanning system enables efficient and selective downloading of files. A scanning mechanism associated with the scanning system captures images of documents. Then, a translator analyzes the captured images to produce data files. When desired, a system controller of the scanning system transmits sufficient data from the data files such that thumbnail images of the data files can be produced. After viewing the thumbnail images, a user selects one of the data files, and the system controller transmits or downloads the selected data file in response. The selected data file can be transmitted to a computer system, which renders the selected data file to a user, or the selected data file can be transmitted directly to a printer, which prints an image of the selected data file.

The switching transistors in multiple switching regulators sharing the same input power source are coordinated to lower the peak current drain on the input power source. The turn on times of the transistors in each regulator are set so that each switching transistor turns on at a predetermined time in a cycle. The predetermined time for each regulator is chosen so that the maximum peak current drain on the input power source is minimized. The predetermined times may be changed on-the-fly by inputs to the system when information about current or projected output loads are known. The transistors in each regulator may also be turned on when the transistor in the previous regulator in a sequence turns off. Another embodiment lets the regulator with the largest change in input current over a cycle run independently. The other regulators then switch in a designated order, or at designated times after the first regulator turns its switch off.

Disclosed is an optical disk handling system having two control system to provide the motions necessary to move optical disk cartridges from storage holding cells to an optical drive. During initialization, the cartridge handling system uses shaft encoders, along with current or voltage feedback from the motors, to calibrate the home locations of the mechanisms. The system determines the home position for vertical movement of the transport as well as the top and bottom positions used for the translate operation. The system then calibrates the plunge movement, the flip movement, and the translate movement. Finally, the system determines whether the path for all the movements is free of obstructions.

A virtual closet stores and presents virtual representations of physical items. The virtual representations may include virtual representations of items owned by a user, items the user would like to own, and memorabilia items for the user. The virtual closet may provide a number of functions. In some embodiments, the virtual closet may be used to facilitate selling items on online selling platforms by providing information (including virtual representations of the items) from the virtual closet to the online selling platforms to place the items for sale. The virtual closet may also be used in some embodiments to facilitate providing advertising targeted to the user based on information available to the virtual closet.
摘要:
Pixels in an array of image sensor pixels contain photo-sensors and circuits having inputs connected to the photosensors. The circuits have feedback loops for reducing fixed pattern noise in the array. Output from each pixel is used to latch a multibit counter value supplied by a global counter. Each feedback loop preferably includes a pair of alternately-toggling switching transistors to minimize unwanted charge injection. An image sensor according to the invention can be used for, e.g., motion sensing.
摘要:
Pixels in an array of image sensor pixels contain photo-sensors. In response to illumination of a photo-sensor, an initial signal is generated. Multiple comparison signals are also generated based on the initial signal. One of the comparison signals remains internal to the pixel, and other comparison signals are transmitted to neighboring pixels. Within a pixel, the internal comparison signal is compared to a sum of comparison signals received from neighboring pixels. Based on the comparison, a data value may be latched and used for indicating a relative difference in pixel illumination.
