Abstract: Apparatus for measuring reflected or transmitted light is described. The apparatus comprises filter type spectrophotometer having a wavelength range of from about 200 nm (nanometers) to about 1,100 nm which includes a sample illuminating light source capable of producing an extremely intense light of short duration; light diffusing means; a light filter for transmission of a selected wave-length; at least two independent light sensing means; and separate means defining light transmission paths for the passage of light from the light source to one light sensing means and from the illuminated sample to the other light sensing means.

Abstract: A method and apparatus for converting radiant energy levels to digital data wherein an image sensor is provided having at least one row of sensor elements each including a light sensitive capacitor and an access switch and which changes state and produces a corresponding binary output signal when a predetermined charge threshold is exceeded by the capacitor whose charge is a function of intensity and period of an illumination. The row of elements is first calibrated by illuminating same with a reference light source and sensing at a first frequency (F) such that approximately one half of the elements change state and counting the digital output signals corresponding to the changes of state to obtain a first number (B). Thereafter, the row is illuminated with an unknown light source which has a lower radiant energy level than that of the reference light source and senses at a frequency F/2. The digital output signals corresponding to the changes of state are counted to obtain a second number (A). The numbers A and B are compared to produce a digital "1" signal when A > B and a digital "0" when A 1 . The sensing and comparing are repeated for each successive bit N 2 , N 3 ...N k of a K bits of digital data at successive sensing frequencies in accordance with

In a preferred embodiment the apparatus includes a light diffusing integrating sphere. In another embodiment, a replaceable or repositionable module can be used to convert the apparatus from reflectance to transmittance spectrophotomer.

Abstract: Test device apparatus is disclosed containing a electrically conductive region which provides information concerning the nature of the test device and/or its position. In a preferred embodiment a conductive strip is applied to a test device and used to determine the identification of the test device, the position of the test device and/or calibrate an instrument which is used to read the test device. The conductive strip generates a signal by measuring the resistance ratio of the electrical path through its conductive region using three or more electrodes or probes. The signal obtained by the electrodes is used to determine the characteristics indicated above or to program operational parameters within an instrument used to analyze the test device.

Abstract: A sensor-integrator utilizes a light sensing diode directly connected to the inputs of an operational amplifier. The operational amplifier forms part of a dual-slope integrator and directly integrates the current generated by the light sensing diode thereby eliminating the need for preamplifiers and diode switching circuitry.
