Abstract
Abstract A device for monitoring the gait of a horse comprises a device (4) for measuring displacement parameters of the horse (2) along at least one axis (Z), processing device (5, 8) for processing the signals coming from the measuring device (4), microprocessor for comparing the amplitude of the output signals from the processing device means with at least one given value characterizing a gait error of the horse (2), and a device (10) for indicating a gait error.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
195 words
Device for monitoring the gait of a horse to indicate if the horse has committed a gait error by changing its gait from trotting to galloping, comprising: measuring means (4) for measuring displacement parmaters of the horse (2) along at least one axis (Z), said measuring means producing an output signal having an amplitude corresponding to the measured parameters, processing means (5, 8) for processing the signals from the measuring means, comprising means (16, 17) for comparing the amplitude of the output signals from the processing means with at least one predetermined value which corresponds to an output signal characterizing a given gait of the horse, thereby to determine whether the horse is trotting or galloping and indicating means (10) for inidicating if the horse is trotting or galloping, said measuring means (4) being arranged in a first unit (1) carried by the horse (2) and additionally comprising independent means (11) for supplying electrical energy to the circuits of this first unit and means (6) for transmitting data to means (7) for receiving these data, provided in a second unit (3) separated from the first unit and in which the indicating means (10) are arranged.
Claim 2
Dependent Claim
195 words
Device for monitoring the gait of a horse to indicate if the horse has committed a gait error by changing its gait from trotting to galloping, comprising: measuring means (4) for measuring displacement parmaters of the horse (2) along at least one axis (Z), said measuring means producing an output signal having an amplitude corresponding to the measured parameters, processing means (5, 8) for processing the signals from the measuring means, comprising means (16, 17) for comparing the amplitude of the output signals from the processing means with at least one predetermined value which corresponds to an output signal characterizing a given gait of the horse, thereby to determine whether the horse is trotting or galloping and indicating means (10) for inidicating if the horse is trotting or galloping, said measuring means (4) being arranged in a first unit (1) carried by the horse (2) and additionally comprising independent means (11) for supplying electrical energy to the circuits of this first unit and means (6) for transmitting data to means (7) for receiving these data, provided in a second unit (3) separated from the first unit and in which the indicating means (10) are arranged.
Claim 3
Dependent Claim
42 words
Device according to claim 1, wherein the processing means (5, 8) comprises first selecting means (14) for selecting signals from a first frequency range of the parameters from the measuring means in order to determine a change of gait of the horse.
Claim 4
Dependent Claim
16 words
Device according to claim 1 or 2, wherein the said axis is a vertical axis (Z).
Claim 5
Dependent Claim
18 words
Device according to claim 2, wherein the first frequency range is from 1.5 to 2.5 Hz 1 .
Claim 6
Dependent Claim
32 words
Device according to claim 2, wherein the processing means (5, 8) comprises second selecting means (15) for selecting signals from a frequency band, twice the first, of displacement parameters of the horse.
Claim 7
Dependent Claim
91 words
Device according to claim 5, wherein output signals from the first and second selecting means (14, 15) are passed to the inputs of the comparing means (16, 17) for comparing these signals with predetermined values corresponding to the gallop and the trot of the horse respectively, the outputs from these comparators then being processed in a data processing unit in order to determine a gait error of horse, a correct trotting gait (19) or a questionable gait (21) of the latter as a function of the result of the comparing means.
Claim 8
Dependent Claim
14 words
Device according to claim 1, wherein processing means arranged in the first unit (1).
Claim 9
Dependent Claim
18 words
Device according to claim 1, wherein the comparing means (16, 17) are arranged in the second unit (3).
Claim 10
Dependent Claim
29 words
Device according to claim 1, 7 or 8, wherein the second unit (3) comprises means (9) for recording the data, connected to the output of the receiving means (7).
Claim 11
Dependent Claim
39 words
System for monitoring the gait of horses during a trotting race wherein the gait of each horse is monitored by means of a device according to claim 1, and wherein each device transmits its data on a separate frequency.
Claim 12
Dependent Claim
34 words
System according to claim 10, wherein the second units of each of the devices are grouped together in a common unit comprising means for scanning the various frequencies and error-indicating means for each horse.
