摘要:
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.
摘要:
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 analysing the detected values to determine a rate of change of light emissions during the subsequent measurement period, due to cell-bound ATP being released and reacting with the reagent, and at least where the thus determined rate of change of light emissions indicates a level of bacteria and/or somatic cells in the sample above a threshold, generating a signal (33).
