Patent ID: 7478563

Claim:
A portable apparatus for use with a portable computer in measuring the tension of a stressed cable, the apparatus comprising: a. two clamps, wherein each clamp comprises two clamping members pivotally joined and capable of being actuated into an open and closed position by a distal actuator, the pivot further comprising a first torsion spring biased to retain the clamping members in a closed position except when the distal actuator is actuated, and the proximal ends of the two clamping members, when in the closed position, defining at least one interior space sized to receive the stressed cable; b. a circuit board connected to the clamps and comprising: i. an accelerometer for measuring the transverse acceleration of the stressed cable; ii. a converter for receiving the transverse acceleration data of the stressed cable and converting it into an analog signal based on variations in voltage; and iii. a circuit that receives the analog signal from the converter and is capable of transmitting said analog signal; and c. a portable power source, such as a battery or a photo cell.
