    摘要： An electroimpedance tomograph is provided with a plurality of electrodes placed on a body, measuring circuits that process the voltage signals recorded by the electrodes, and a control unit that supplies two, preferably adjacent electrodes each with an alternating current. The control unit has a preset feed frequency performed in different states and different preset feed frequencies performed at different frequencies. The control unit processes the processed voltage signals of all other electrodes to reconstruct the impedance distribution of the body in the electrode plane. To make the EIT more insensitive to electromagnetic interferences, the control unit provides for an automatic setting of the current feed frequency/frequencies to record a background frequency spectrum by detecting the electrode voltage signals over a preset period of time and record them as a voltage time series and transform them into a frequency spectrum. The control unit searches in the background frequency spectrum for a frequency (different states) or frequencies (different frequencies) that leads to a useful signal to background ratio above a preset threshold value when used as a feed frequency.

    摘要： There is described a decodable indicia reading terminal which in one embodiment can capture and process a certain (e.g., a first) and a subsequent (e.g., a second) frame of image data, wherein the certain and the subsequent frames have different imaging attributes. In one embodiment the attributes between certain and subsequent frames are differentiated in that the certain frame represents light incident on pixels of a first image sensor and the subsequent frame of image data represents light incident on pixels of a second image sensor spaced apart from the first image sensor. Additionally, or in the alternative, the attributes between certain and subsequent frames can be differentiated in that the first frame represents light incident on an image sensor under a first illumination profile and the subsequent frame represents light incident on pixels of an image sensor under a second illumination profile. In one embodiment imaging attributes of a frame subject to decoding are maintained constant for each frame subject to processing during a time that a trigger signal remains active. In one embodiment the certain and subsequent frames can be processed to yield partial decoding results and the partial decoding results can be combined to form a complete decoding result.

    摘要： An indicia reading terminal can include a multiple setting imaging lens assembly and an image sensor having an image sensor array. In one embodiment, an indicia reading terminal in an active reading state can cycle through a set of different lens settings, expose pixels of an image sensor array during an exposure period when each new lens setting is achieved, and attempt to decode decodable indicia represented in frames of image data captured corresponding to each exposure period. In one embodiment, movement of an imaging lens assembly lens element can be provided with use of a hollow stepper motor.

    摘要： Systems, methods and apparatus relate to handling and processing glass, such as glass for use in liquid crystal displays, involving a measurement device, such as a distortion gauge, residing in an environmentally controlled measurement room, and a cassette loading device for storage and conveyance of glass between the measurement device and other components of a glass handling and processing system residing with the cassette loading device in a preparation room. A mail-slot opening may be present in a wall separating the measurement room from the preparation room. A gauge conveyor may convey glass between the cassette loading device and the measurement device. A distortion gauge may measure a reference value of the product glass with respect to reference marks on a glass reference plate of the distortion gauge. Other examples of a measurement device include a warp gauge, a stress gauge, a thickness gauge, and a compaction gauge.
