Figure Lengend Snippet: (A) Intravaginal Transducer Assembly and (B) Instrumentation Module circuit board with added BLE 113 Bluetooth Module. A rechargeable battery is placed in the contacts on the left side of the board, which can hold enough charge for approximately ten hours of continual use. (C) Intravaginal Transducer and Instrumentation Module combined with parallel bar speculum to measure vaginal closure force. Forces placed on the distal end of the upper dynamic bill are transferred to IVT at the proximal end of the upper bill and is measured as pressure by the IVT.

Article Snippet: To reduce the design cycle time of incorporating live data streaming, we decided to incorporate a stand-alone Bluetooth Low Energy (BLE) module (BLE113, Bluegiga).

Figure Lengend Snippet: (A) Screen layout of the companion app for the speculum. (B) Companion App signal processing flowchart. The “Connect” buttons at the top of the screen establish Bluetooth connections to either the Instrumentation Module (which initiates data streaming from the speculum) or the Remote Pedal (which marks the beginning of activities). The Force Graph displays force in real-time and changes color from red to yellow when actively recording an activity. The Force Readout and Force Magnitude bars show the live measurement. When a recording session is initiated all of the Event Labels are greyed out (inactive). The Event Labels then turn red (ready for measurement) as the participant protocol progresses. They then turn yellow when actively recording an event. The recording is initiated using the foot pedal switch and then continues for 10 seconds. The Event Labels then turn green when event recording is complete. The app automatically runs through the events from left to right and after all events are recorded, the calculate button becomes available (shown unavailable). After selecting the calculate button, the tracing for the kegel rep activity is plotted and the user selects the three repetitions for analysis. Once the repetitions have been selected the calculate button is pressed again and the results of the visit are calculated and displayed for the user.
