Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
101 words
A method for the examination of a condition of a ruminant animal comprising sampling odors from at least one part of the animal with an electronic olfactory sensor thereby identifying a specific aspect of the animal's condition, including establishing an examination region in the air around a part of the animal to be examined, purging the region, drawing a sample of air from the region, applying the sample to the sensor and providing a sensor output indicative of any response of the sensor to said sample which determines whether the animal is to be one of milked, cleaned or examined further.
Claim 2
Independent Claim
101 words
A method for the examination of a condition of a ruminant animal comprising sampling odors from at least one part of the animal with an electronic olfactory sensor thereby identifying a specific aspect of the animal's condition, including establishing an examination region in the air around a part of the animal to be examined, purging the region, drawing a sample of air from the region, applying the sample to the sensor and providing a sensor output indicative of any response of the sensor to said sample which determines whether the animal is to be one of milked, cleaned or examined further.
Claim 3
Dependent Claim
18 words
A method according to claim 1 including providing the examination region as a vessel to receive a teat.
Claim 4
Dependent Claim
16 words
A method according to claim 1 including providing the examination region as a structured air flow.
Claim 5
Dependent Claim
35 words
A method according to claim 1 including examining the condition of a milking animal presenting for milking and controlling the progress of the milking process thereafter in dependence on the identified condition of the animal.
Claim 6
Dependent Claim
16 words
A method according to claim 4 including examining the animal before entry to a milking position.
Claim 7
Dependent Claim
68 words
Apparatus for examining the condition of a ruminant animal comprising means for establishing an examination region in air around a part of the ruminant animal to be examined, means for purging the region, means for drawing a sample of air from the region, means for applying said sample to an electronic olfactory sensor and means for supplying a sensor output indicative of the condition present in the animal.
Claim 8
Dependent Claim
68 words
Apparatus for examining the condition of a ruminant animal comprising means for establishing an examination region in air around a part of the ruminant animal to be examined, means for purging the region, means for drawing a sample of air from the region, means for applying said sample to an electronic olfactory sensor and means for supplying a sensor output indicative of the condition present in the animal.
Claim 9
Dependent Claim
21 words
Apparatus according to claim 6 in which the examination device is an open-top vessel into which a teat can be inserted.
Claim 10
Dependent Claim
15 words
Apparatus according to claim 6 in which the examination device is a teat-cup like structure.
Claim 11
Dependent Claim
47 words
Apparatus according to claim 6 in which the purging is arranged to at least reduce the inclusion of general ambient air in the sample, ensuring that the sample is representative of material diffusing from the teat or other part of the ruminant animal or a substance thereon.
Claim 12
Dependent Claim
21 words
Apparatus according to claim 6 in which the purging air is a reference for the sensor before a sample is taken.
Claim 13
Dependent Claim
31 words
Apparatus according to claim 6 in which the sensor is based on a conducting polymer, a metal oxide or other sensing material for olfactory purposes, with associated electronic signal processing circuitry.
Claim 14
Dependent Claim
53 words
Apparatus according to claim 6 in which the sensor is arranged to sense diffusion from the teat or another part of the animal or a substance thereon of organic material characteristic of one or more of faecal material, blood, earth, the state of the metabolic process and the conditions of oestrus or ketosis.
Claim 15
Dependent Claim
12 words
Apparatus according to claim 6 arranged for manual operation by an operator.
Claim 16
Dependent Claim
13 words
Apparatus according to claim 6 arranged for operation by an automatic milking apparatus.
Claim 17
Dependent Claim
22 words
Apparatus according to claim 6 including means to control a sequence of operations including a purge operation and a sample taking operation.
Claim 18
Dependent Claim
26 words
Apparatus according to claim 6 including means to cause flow of said purge and said sample and means to control the means to cause said flows.
Claim 19
Dependent Claim
55 words
Apparatus according to claim 6 including means to collect breath or other flow containing an odor of the animal as a sample, means to purge said collecting means, sensing means to receive said sample and identify at least one specific condition of the animal and means to supply an indication of said condition being present.
Claim 20
Dependent Claim
19 words
Apparatus according to claim 6 arranged to sense for at at least one of the conditions ketosis and oestrus.
Claim 21
Dependent Claim
15 words
Apparatus according to claim 17 arranged for mounting on a stall for a ruminant animal.
Claim 22
Dependent Claim
16 words
Apparatus according to claim 6 arranged to produce a structured air flow to collect an odour.
Claim 23
Dependent Claim
21 words
An apparatus according to claim 6, wherein said sensor output indicates whether the animal should be milked, cleaned or examined further.
