    摘要: Determining matching degrees of information categories and displayed information is disclosed. In some embodiments, recorded user selection action information with respect to displayed information is analyzed to determine which pieces of displayed information have been selected and which pieces were displayed but not selected. In some embodiments, a matching degree for an information category is determined based on the recorded user selection information with respect to displayed information. In some embodiments, based on this matching degree determined for the information category, it is determined whether the information to be displayed for the information category is to be adjusted for a subsequent event in which information of the information category is to be displayed.

    摘要: In a method and system for controlling gain in an RF receiver, an RF signal is analyzed over different attack and decay windows, from which the receiver determines (1) if the signal is in an attack condition with dip values below a threshold level thus indicating a need for increasing signal gain, or (2) if the signal is in a decay condition with threshold values above a threshold level thus indicating a need for decreasing signal gain. The receiver applies attack and decay windows of different sizes and in an asynchronous manner to create a gain control scheme that is insensitive to transient effects such as channel interference and deep fading that affect the intensities of an in-band signal.

    摘要: A vision system is provided to determine a positional relationship between a photovoltaic device wafer on a platen and a printing element, such as a printing screen, on a remote side of the photovoltaic device wafer from the platen. A source emits ultraviolet light along a path that is transverse to a longitudinal axis of an aperture through the platen, and a diffuser panel is located along that path. A reflector directs the light from the diffuser panel toward the aperture. A video camera is located along the longitudinal axis of the aperture and produces an image using light received from the platen aperture, wherein some of that received light was reflected by the wafer. A band-pass filter is placed in front of the camera to block ambient light. The use of diffused ultraviolet light enhances contrast in the image between the wafer and the printing element.

    摘要: A method of identifying a reset condition includes the steps of determining if a stored value is equal to a specified value, executing a first mode if the stored value is not equal to the specified value, and executing a second mode if the stored value is equal to the specified value. The second mode also includes the step of setting the stored value to a value different than the specified value.
