Abstract: A timing apparatus for an aquatic timing system includes a rigid and planar primary portion, a flange portion extending at an angle from the primary portion, a vibration sensor coupled with the flange portion, and a controller. The vibration sensor is operable to detect a touch event occurring on the primary portion and respond to the touch event by generating a signal. The controller is in communication with the vibration sensor and is configured to receive the signal from the vibration sensor and identify a touch event from the signal. The vibration sensor may be operable to detect the touch event by detecting a vibration on the flange portion that originated from the touch event on the primary portion.

Abstract: An aquatic timing system includes a plurality of timing apparatuses, each timing apparatus including a primary portion with a front touch area and a display for presenting visual information, the display forming part of the front touch area. Each timing apparatus further includes a flange portion extending from an edge of the primary portion and a sensor for detecting a touch event occurring on the front touch area of the primary portion. An enclosure is mounted on the flange portion and contains a controller in communication with the sensor. The controller is configured to receive a signal from the sensor and identify a touch event from the signal, communicate a wireless signal to an external device including event time information associated with the timing apparatus, and receive a wireless signal containing event information and cause the display to present the event information.

Abstract: The present invention relates to time measurement apparatus and method for measuring, with picosecond precision, intervals between single edged events, where each measured interval comprises the summation of a rough clock count and fine or calibrated vernier counts of measured fractional clock periods before and after each START and STOP event selected from a calibrated vernier memory. The calibrated vernier memory takes the form of a table of linear voltage versus time developed using pseudo-random generated measurement events of random duration and random separation.
