摘要： A method for calibrating a clock and data recovery circuit may include configuring a phase detector as a bang-bang phase detector. The bang-bang phase detector may be used to determine a phase difference between a sampling clock provided by an interpolator and a calibration signal. The phase detector may also be configured as a linear phase detector. While using the linear phase detector, a linear phase detector parameter may be adjusted such that the phase difference between the calibration signal and the sampling clock is zero, while keeping the phase of the sampling clock fixed.

摘要： Apparatus and methods for rotational frequency detection are disclosed. In one embodiment, a rotational frequency detector is configured to receive samples taken from a serial data stream and to generate a frequency up error signal or a frequency down error signal. The rotational frequency detector processes a first set of samples to generate first transition data, which may be stored in a memory. The rotational frequency detector processes a second and third set of samples to generate second and third transition data. The frequency up or frequency down error signal is generated based at least partly on the first, second or third transition data. This configuration can reduce the maximum operating frequency of the rotational frequency detector, thereby simplifying the rotational frequency detector design to a point that a conventional static digital CMOS circuit design flow can be used to design the rotational frequency detector.

摘要： A signal is transmitted into a computer in response to an image on a display screen of the computer such that the computer operates in response to the signal; this includes moving a scanner in optical communication with the display screen such that the scanner detects an image (for example, a bar code) displayed on the screen and generates the signal in response. One or more computers may be used, and this may be used for vending a product or other purposes. With or without such scanning, a portion of a store environment may be displayed on a screen of a computer, including showing images of actual products for sale at the store, in which images of actual products are accessed via the computer from a database containing in-store images recorded in the store during a period of non-existent or minimal customer presence in the store. A vending system is also disclosed.
