Wireless sensor device and software system for measuring linear position of a rotating object

A computer system comprising:

• a sensor device that is affixed to an object comprising:
• one or more processors;
• a gyroscopic sensor coupled to the one or more processors and configured to measure rotational motion of the sensor device;
• a wireless network transceiver coupled to the one or more processors;
• a non-transitory computer-readable storage medium coupled to the one or more processors and storing one or more sequences of instructions which when executed by the one or more processors cause the one or more processors to perform:
• using the gyroscopic sensor, detecting rotational movement of the sensor device, the rotational movement of the sensor device being determined by the rotational movement of the object to which the sensor is affixed;
• generating one or more signals that represent rotational movement based on the detected rotational movement from the gyroscopic sensor;
• transmitting the one or more signals that represent rotational movement via the wireless network transceiver to a mobile computing device that is separate from the sensor device;
• the mobile computing device comprising a second non-transitory computer-readable storage medium storing downloadable application instructions which when downloaded to and executed by the mobile computing device cause the mobile computing device to perform:
• receiving the one or more signals that represent rotational movement from the sensor device;
• receiving object parameter information that describes one or more attributes of the object to which the sensor device is affixed;
• assigning, to the one or more signals that represent rotational movement, a timestamp value obtained from an internal clock of the mobile computing device;
• generating one or more angular velocity datasets comprising a plurality of values representing a plurality of measurements based on the one or more signals that represent rotational movement and the timestamp values that have been assigned to the one or more signals that represent rotational movement;
• generating one or more object datasets describing motion or position of the object over a particular period, each of the one or more object datasets comprising calculated data values with associated timestamps based on the object parameter information and the one or more angular velocity datasets, wherein the calculated data values are associated with timestamp values that were assigned to the one or more signals that represent rotational movement used to generate the plurality of values of the one or more angular velocity datasets;
• generating two or more sets of graphical representations from one or more sets of the calculated data values within the one or more object datasets, wherein each graphical representation of the two or more sets of graphical representations includes a subset of the one or more sets of the calculated data values and is associated with a particular timestamp value of the timestamp values;
• displaying, on a display device communicatively coupled to the mobile computing device, two or more graphs, each of the graphs obtained from a distinct set of the two or more sets of graphical representations.
