Abstract

A touchpad useful in timing competitive sporting events such as swim meets includes a touch plate having a front surface and a back surface, one or more accelerometers coupled to the touch plate, electrical circuitry in communication with the accelerometers to detect motion indicative of a user'"'"'s touch, and communications circuitry to transmit information indicative of a user'"'"'s touch to a display, storage device or other remote unit. The back surface of the touch plate may have resilient ridges or a backing structure that more positively ensures contact recording. The circuitry may battery powered with rechargeable batteries. The communications circuitry may use wireless RF technology such as WiFi synchronized absolute time to transmit the touch information to a central timing system. In competitive swimming events, the communications circuitry utilizes a standard Colorado Timing systems banana plug.

Claims

1. A touchpad useful in timing competitive sporting events, comprising:

a touch plate having a front surface and a back surface;

one or more accelerometers coupled to the touch plate;

electrical circuitry in communication with the accelerometers to detect motion indicative of a user'"'"'s touch; and

communications circuitry to transmit information indicative of a user'"'"'s touch to a display, storage device or other remote unit.

2. The touchpad of claim 1, wherein the accelerometers are one-, two- or three-axis accelerometers.

3. The touchpad of claim 1, wherein the back surface of the touch plate has resilient ridges or backing structure.

4. The touchpad of claim 1, wherein the circuitry is battery powered.

5. The touchpad of claim 4, wherein the batteries are rechargeable.

6. The touchpad of claim 1, wherein the communications circuitry utilizes wireless WiFi technology.

7. The touchpad of claim 1, wherein the communications circuitry utilizes wireless technology synchronized absolute time to transmit the touch information to a central timing system.

8. The touchpad of claim 1, wherein the communications circuitry utilizes a standard Colorado Timing systems banana plug signals associated with competitive swimming events.
