Navigation wristwear |
摘要 |
A navigation wristwear device comprises a GPS receiver fully disposed in a wrist watch type housing. A transparent microwave patch antenna is patterned of indium-tin-oxide on sapphire in front of an LCD time, position and velocity display. A bezel provides a protective window. A low-noise amplifier, downconversion, code processing and navigation processing are all provided on a single integrated circuit. Photovoltaic solar cells to each side of the LCD help keep a battery charged.
