Abstract: A method of testing an organic sample to provide an indication of the level of bacteria and/or number of somatic cells present in the sample, the method including collecting the sample and contacting the sample with a reagent which reacts with ATP to produce light emissions, and subsequently, at the beginning (O) of a measurement period (A, B), contacting the sample with an extractant in the presence of the reagent, the extractant rupturing cells present in the sample to release cell-bound ATP to react with the reagent to produce light emissions, and immediately after contacting the sample with the extractant, detecting the light emissions with a light detecting device (18), and the method includes during an initial measurement period (A) immediately after contacting the sample with the extractant, detecting the level of light emissions, and in a subsequent measurement period (B), detecting the level of light emissions, statistically analyzing the detected values to determine a rate of change of light emissio

Abstract: The present invention is electronic eye-pointing assisted alternative and augmented communications device that stores communicated characters in electronic memory and displays them on display panels on the device. The device has a library of phrases stored in electronic memory that can be called up and displayed using two character codes. The device can be connected to a computer to display the communicated characters on a large screen and to enable the device to be used as an input device for an application or to edit the library of phrases or change the language of use.
