Abstract: A portable wireless data transfer and display device comprises a user interface, a communication module, a display, and a short-range wireless communication module configured to wirelessly receive vehicle data from a data acquisition device mounted inside a vehicle when in close proximity to the data acquisition device. The device is configured to accept inputs of driver information from a user via the user interface. The device is configured to associate the inputs of driver information with the vehicle data, and further includes a long-range wireless communication module configured to send the vehicle data and the driver information, and the association of the vehicle data and the driver information through the communication module to a remote network device via a long-range wireless network. The device is further configured to present at least one of: the vehicle data, the driver information, processed data, driver communications to a user via the display.

Abstract: A data acquisition device includes a wired module configured to provide a wired connection to a vehicle for gathering vehicle data from the vehicle during operation of the vehicle. The data acquisition device is configured to be mounted inside the vehicle. The data acquisition device further includes short-range wireless communication module configured to wirelessly send the vehicle data in real-time to a portable wireless data transfer and display device in close proximity to the data acquisition device during operation of the vehicle.

Abstract: A brake stroke sensor is disclosed. In particular, a digital brake stroke sensor capable of indicating a position of pushrod linear displacement is disclosed. The brake stroke sensor includes a prism attached to the pushrod. The prism includes a number of markers to code position information. Sensors read the coded position information and electronics convert the position information to a form useable humans.

Abstract: A brake stroke sensor and an steering sensor are individually and collectively provided. A brake stroke sensor includes a force-receiving plate, a second plate movable relative to the force-receiving plate, a spring disposed between the plates and operatively connected to the pushrod, a strain gauge bridge mounted on the force-receiving plate and a microcontroller capable of converting the strain gauge bridge signal into digital data. A steering sensor includes a mechanical interface operatively connected to a nonmoving member and a moving member, an encoder capable of transforming the rotational motion of the mechanical interface into an electrical signal, and a microcontroller capable of calculating, from the electrical signal, a count indicative of the relative positions of the members. A combined brake stroke and steering sensor may include individual and common elements of both the brake stroke and steering sensors described above.

Abstract: A pressure/force transducer having a sensor body with a load-receiving member at one end, a load button positioned within the sensor body and having a curved surface in surface-to-surface continuous contact with the load-receiving member, a piezoelectric plate positioned within the sensor body and in contact with the load button, and a signal processor for converting the electrical charge produced by the piezoelectric plate into a humanly perceivable signal. A preloading member is connected to the sensor body so as to adjustably force the load button into surface-to-surface contact with the load-receiving member. The load-receiving member is integrally formed with the sensor body. This load-receiving member has a radiused corner connecting the member to the sensor body. The load button is a generally cylindrical member with a generally curved surface in contact with the load-receiving member.

Abstract: A foot-strike measuring system and method using a pair of tandem plates each having at least two sensors along the direction of travel for measuring force. By monitoring the signals on the sensors at the adjacent edges and comparing with those on the nonadjacent sensors, the system determines whether one foot is on both plates or one foot is on each plate. This allows collecting and tracking sensor signals for each foot separately. Center of pressure is also calculated using the speed of the treadmill.
