Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
98 words
System for performing skip-rope exercises comprising: a. a skip-rope having a mid-portion that has a metallic component; and b. a floor mat having a generally flat surfaced major portion for being tread upon by an exerciser while using said skip-rope, said major portion embodying an electrical coil wherein an electrical response is thereby created in said coil when said mid-portion passes in close proximity to said coil, and a read-out display portion adjoining said major portion having instrumentation which is responsive to, and which reads out the number of passes to said coil made by said skip-rope mid-portion.
Claim 2
Dependent Claim
98 words
System for performing skip-rope exercises comprising: a. a skip-rope having a mid-portion that has a metallic component; and b. a floor mat having a generally flat surfaced major portion for being tread upon by an exerciser while using said skip-rope, said major portion embodying an electrical coil wherein an electrical response is thereby created in said coil when said mid-portion passes in close proximity to said coil, and a read-out display portion adjoining said major portion having instrumentation which is responsive to, and which reads out the number of passes to said coil made by said skip-rope mid-portion.
Claim 3
Dependent Claim
12 words
System as defined in claim 1 wherein said metallic component is ferrous.
Claim 4
Dependent Claim
12 words
System as defined in claim 1 wherein said metallic component is magnetized.
Claim 5
Dependent Claim
30 words
System as defined in claim 1 wherein said instrumentation includes a high-gain af amplifier connected to said coil, said amplifier feeding to a relay which feeds to a counter circuit.
Claim 6
Dependent Claim
27 words
System as defined in claim 1 wherein said instrumentation includes a rf oscillator which will shift frequency in response to a change in inductance of said coil.
Claim 7
Dependent Claim
24 words
System as defined in claim 1 wherein said instrumentation includes a resonant rf tank circuit responsive to a change in inductance of said coil.
Claim 8
Dependent Claim
20 words
System as defined in claim 1 wherein the upper surface of said major portion has a smooth, low friction finish.
Claim 9
Dependent Claim
28 words
System as defined in claim 1 wherein said display portion has a display panel which lies generally horizontally in close vicinity to said major portion and faces upwardly.
Claim 10
Dependent Claim
27 words
System as defined in claim 1 wherein display portion has a display panel which lies in close vicinity to said major portion and which faces obliquely upwardly.
Claim 11
Dependent Claim
16 words
System as defined in claim 1 wherein said display portion includes a pulse-rate sensor and read-out.
Claim 12
Dependent Claim
17 words
System as defined in claim 1 wherein said major portion is composed of cushioned, shock absorbing material.
Claim 13
Dependent Claim
47 words
System as defined in claim 1 including means embodied in said skip rope for sensing an exerciser's pulse rate and for transmitting a signal carrying said pulse rate information, and means located in said display portion for receiving and processing said signal and displaying said pulse rate.
Claim 14
Dependent Claim
16 words
System as defined in claim 12 wherein means for receiving said signal includes said electrical coil.
Claim 15
Dependent Claim
23 words
System as defined in claim 12 wherein said sensing means includes instrumentation embodied in the hub of a handle of said skip rope.
Claim 16
Dependent Claim
43 words
System as defined in claim 1 including means embodied in said skip rope sensing an exerciser's pulse rate and instrumentation connected to said sensing means and contained in the hub of a handle of said skip rope for reading out said pulse rate.
