Method and system for detecting urine and/or feces
First Claim
1. A method of detecting urine and feces comprising:
- detecting the concentration of a gas component indicative of urine and the concentration of a gas component indicative of feces by;
registering, for each detected gas component, a characteristic corresponding to variation over time of the concentration of each detected gas component;
determining whether each registered characteristic conforms to a predetermined characteristic corresponding to variation over time of a concentration of a corresponding gas component, wherein the predetermined characteristic is independent of the concentration of the detected gas component and the determination is dependent upon how the concentration of the detected gas component varies over time;
indicating a presence of urine if the registered characteristic of the detected gas component indicative of urine generally conforms with the predetermined characteristic of the corresponding gas component; and
indicating a presence of feces if the registered characteristic of at least one gas component indicative of feces generally conforms to the predetermined characteristic of the same gas component.

Abstract
A method of detecting urine and/or feces is disclosed, which includes detecting the concentration of at least one gas component indicative of urine and the concentration of at least one gas component indicative of feces. The method also includes registering, for each gas component, a characteristic corresponding to the variation over time of the concentration of each gas component; comparing the registered characteristic with a predetermined characteristic for the corresponding gas component; indicating a presence of urine if the registered characteristic of at least one gas component indicative of urine generally conforms with the predetermined characteristic of the same gas component; and indicating a presence of feces if the registered characteristic of at least one gas component indicative of feces generally conforms to the predetermined characteristic of the same gas component. A system for detecting urine and/or feces is also disclosed.

12. A system for detecting urine and feces, comprising:
-
a sensor unit comprising a gas sensor for detecting the concentration of a gas component indicative of urine and a gas sensor for detecting the concentration of a gas component indicative of feces; and a receiving unit connectable to the sensor unit, and; wherein said receiving unit is arranged for registering based on said detected concentration for each gas component, a characteristic corresponding to variation over time of the concentration of each detected gas component, and determining whether each registered characteristic conforms to a predetermined characteristic corresponding to variation over time of a concentration of a corresponding gas component, wherein the predetermined characteristic is independent of the concentration of the detected gas component and the determination is dependent upon how the concentration of the detected gas component varies over time, and wherein the receiving unit is arranged for providing an indication of any presence or urine and/or feces based on information from said gas sensors if the registered characteristic of said gas component indicative of urine/feces generally conforms to the predetermined characteristic of the same gas component, and the registered characteristic is determined to conform to the predetermined characteristic if the registered characteristic follows the variation over time of the predetermined characteristic. - View Dependent Claims (13, 14, 15)
