CIO - If you love tech gadgets -- and who doesn't? -- all sorts were on display at the Churchill Club's annual gadget fest this week in Santa Clara. Devices included a collar that tracks your dog's daily exercise, a fork that vibrates when you've eaten too much and a basketball filled with sensors.

For athletes, basketballs and soccer balls have sensors that give feedback to players, such as ball speed and rotation, in order for them to improve their techniques. Some European sports teams are putting sensors into jerseys and football helmets to count and measure the impact of collisions, in hopes of avoiding concussions and other injuries by taking out at-risk players.
For audiophiles, Harper showed off wireless speakers that are great for airplane trips because they cancel out the noise of the engine, although quality of sound suffers with noise cancellation headphones, he says. Harper brought out super small wireless speakers with good sound and plush stuffed animals that danced as music played.
