Abstract
Abstract The detector is mounted on a fishing line carrying a fish-hook and includes a fish-bite detection sensor operable in response to pressure applied by a fish's mouth on a worm rigged onto the fish-hook. The detector includes an oscillator disposed near the fish-hook, which outputs a signal in response to actuation of the sensor, and a receiver disposed away from said fish-hook, thus enabling an angler on the shore to detect that a fish has bitten the worm.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
A detector for detecting a bite of a fish, on a fishing line, said detector comprising: a fish-bite detection sensor for sensing a pressure caused by a bite of said fish on at least one of a fish-hook connected to said fishing line and a bait rigged on said fish-hook to thereby detect a bite of said fish, an oscillator electrically connected to said sensor for emitting an output signal responsive to said sensor sensing said pressure, said oscillator being disposed in the proximity of said fish-hook and including a power source, a receiver for receiving said output signal from said oscillator, said receiver being disposed away from said fish-hook.
Claim 2
Dependent Claim
110 words
A detector for detecting a bite of a fish, on a fishing line, said detector comprising: a fish-bite detection sensor for sensing a pressure caused by a bite of said fish on at least one of a fish-hook connected to said fishing line and a bait rigged on said fish-hook to thereby detect a bite of said fish, an oscillator electrically connected to said sensor for emitting an output signal responsive to said sensor sensing said pressure, said oscillator being disposed in the proximity of said fish-hook and including a power source, a receiver for receiving said output signal from said oscillator, said receiver being disposed away from said fish-hook.
Claim 3
Dependent Claim
28 words
A detector for detecting a bite of a fish as set forth in claim 1 wherein said sensor is embedded in a worm rigged on said fish hook.
Claim 4
Dependent Claim
33 words
A detector for detecting a bite of a fish as set forth in claim 1, wherein said sensor and oscillator are separate from each other and connected with each other through a connector.
Claim 5
Dependent Claim
25 words
A detector for detecting a bite of a fish as set forth in claim 1, wherein said sensor and oscillator are integral with each other.
Claim 6
Dependent Claim
23 words
A detector for detecting a bite of a fish as set forth in claim 1, wherein said sensor is mounted on said fish-hook.
