Electronic device for analyzing aqueous solutions
First Claim
1. A device for analyzing a plurality of characteristics of an aqueous solution, comprising:
- a portable hand-held housing having an interior;
a test element receiving port configured to receive a wetted test element;
circuitry in the housing for selectively generating radiation for interrogating a plurality of different portions of a wetted test element when placed within the test element receiving port, for receiving radiation reflected from the test element, and for generating a display responsive to the reflected radiation and indicative of the plurality of different characteristics of the aqueous solution; and
,wherein the test element receiving port is proximate portions of the circuitry generating the radiation and receiving the reflected radiation and the radiation-transmissive test element receiving port comprises;
a slot formed in the housing proximate portions of the circuitry generating the radiation and receiving the reflected radiation;
a radiation-transmissive test element placement member attached to the housing toward a bottom of the slot, closing the slot and isolating an interior of the housing and the circuitry from an exterior of the housing while permitting the generated radiation to pass out of the housing and the reflected radiation to pass back into the housing.

Abstract
An electronic device for analyzing an aqueous solution may comprise a housing, one or more measurement circuits and a control circuit all arranged inside the housing. The housing may be configured to receive a test element. The one or more measurement circuits may be configured to produce one or more corresponding sets of measurement signals relating to an aqueous solution received on the test element. The control circuit may include a memory having instructions stored therein that are executable by the control circuit to process the one or more sets of measurement signals to determine one or more corresponding characteristics of the aqueous solution.

17. A device for analyzing characteristics of an aqueous solution, comprising:
-
a portable hand-held housing having an interior; a test element receiving port configured to receive a wetted test element; a plurality of radiation sources within the housing arranged to transmit radiation through a plurality of different spaced apart portions of a test element receiving port; a plurality of radiation detection circuits within the housing, wherein each radiation detection circuit is associated with a corresponding radiation source to detect radiation reflected from a corresponding portion of a test element and each radiation detection circuit being associated with a different characteristic of the aqueous solution; wherein each radiation detection circuit is configured to generate one or more measurement signals indicative of the associated different characteristic of the aqueous solution in response to detected, reflected radiation; a control circuit disposed within the housing and associated with the radiation detection circuits for determining the different characteristics of the aqueous solution based at least in part on the measurement signals; wherein the test element receiving port is proximate portions of the radiation sources and radiation detection circuits, and the radiation-transmissive test element receiving port comprises; a slot formed in the housing proximate portions of the radiation sources and radiation detection circuits; and
,a radiation-transmissive test element placement member attached to an underside of the housing juxtaposition to the slot thereby closing the slot and isolating the interior of the housing including the radiation sources, radiation detection circuits and control circuit from an exterior of the housing while permitting the generated radiation to pass out of the housing and the reflected radiation to pass back into the housing. - View Dependent Claims (18, 19, 20, 21)
