Abstract: In analyzers where a patient sample is to be dispensed on to a test element from a container, there is a risk that the test elements may be contaminated by spillage of samples within the analyzer. One way of overcoming this problem is to stopper the container whilst it is being handled in the analyzer. However, this introduces a further problem of removing the stopper from the container to enable the patient sample contained therein to be dispensed. Described herein is stopper detector apparatus (30) which can be used in combination with a stopper remover (70) so that stoppered containers (10) of liquid can be automatically unstoppered in an analyzer. The stopper detector apparatus (30) includes a discriminating mechanism (40, 46, 48, 50, 52) for discriminating between a container (10) having a stopper (12), and an unstoppered container, including one with a cup (16) inserted into the top of the container (10). It also includes signal generating means (68) for generating a signal in response to the discriminating mechanism (40, 46, 48, 50, 52) detecting the presence of a stopper (12) in a container (10), the signal being used to actuate the stopper remover (70).

Abstract: An analog-to-digital converter (ADC) includes successive approximation control logic for generating ten-bit binary numbers, a digital-to-analog converter (DAC) (205) having a resistor string (301) and a weighted-capacitor array (303) for converting the ten-bit binary output of the control logic to a known analog voltage, and an analog comparator (207) for comparing the output of the DAC (205) to a reference voltage provided via a tap (305) to the mid-point of the DAC resistor string (301). The unknown analog voltage input to the ADC and the reference voltage are provided to the capacitor array (303) to precharge the array (303) to a voltage equal to the reference voltage minus the unknown analog voltage. The output of the DAC (205) is equal to the known analog voltage plus the reference voltage minus the unknown analog voltage.

Abstract: The present invention provides methods and systems for encoding digital data in the angular orientation of circularly asymmetric halftone dot patterns that are written into the halftone cells of digital halftone images. In keeping with standard practices, the sizes of these halftone dot patterns are modulated in accordance with the grayscale data sample values that are provided to define the image, so the average reflectance or transmittance of each of the halftone cells is modulated to provide a more or less standard halftone rendering of the image. In accordance with this invention, however, provision is made for modulating the angular orientation of the halftone dot patterns in accordance with digital data values, thereby embedding the digital data in the halftone image.
