Apple has been granted patents for a variety of technology ranging from heart rate sensors to electronic drink coasters and tracking systems. Earlier patents detailed sensors and systems geared for sports such as skiing and snowboarding, while the latest documents outline movement-tracking sensors that can be attached to the feet, hands, head, knees and chest.

Apple's illustrations show two individuals competing in martial arts, with sensors placed around the body to track strikes or body positioning. The sensors can also be placed in a boxing glove. Where motion-tracking systems such as the Wii controller serve as input for a virtual environments, the Apple systems integrate with many real-world activities that do not typically involve electronics.

After practicing karate, a teacher could review the impact strengths and reaction times from a customized Apple TV interface. Direct competitors could potentially compare match statistics or progress over time. Other possibilities for Apple TV include NASCAR statistics, enabling viewers to observe real-time data throughout a race.

Along with personal monitoring, the patents describe ski passes that can track a wearer's speed, jumps or flips. Ski patrol could use the data to enforce rules on the slopes. Apple expanded the possibilities to include a wide range of sports such as surfing, motocross, rodeo events, hockey, soccer, biking, and more.

Although Apple has remained quiet regarding any plans to produce a tablet or netbook, one of the recent patents covers new antenna technology for an ultraportable. The examples cover devices such as the iPhone, along with small notebooks.

Apple also appears to be working on technology geared for businesses. An electronic drink coaster could notify restaurant staff when a beverage needs refilled. Customers could also place drink orders directly from the coaster. A shipment tracking system provides a way to monitor shipments for excessive force, with a log showing g-forces at specific levels.
