This invention provides binocular eyeglasses that have linear polarizing lenses to be employed by a golfer to examine the surface of a putting green as an aid in deciding the speed and direction of a puffing stroke. The planes of maximum transmission for the lenses are preferably complementary each lens 45 to horizontal. The polarizing lenses are supported to permit the golfer to rotate the lenses to “tip-up” position out of the line of sight, which enables the golfer to alternatively see a direct view and a polarizer altered view of the putting surface without significant delay of play.

In a sailboat, signals representing relative wind speed and slot wind speed are differentially compared to obtain a signal that represents the increase in wind speed in the slot over the relative wind speed approximately independent of incremental changes in relative wind speed approximately independent of incremental changes in relative wind speed. By observing the differential quantity upon relative adjustment of the sails, a sail setting can be selected to give maximum slot effectiveness. An instantaneously responsive thrust indicator is provided as a guide to overall sail trim effectiveness for maximum driving force on the hull.

A secure communication system uses narrow beam laser transmissions from a relay station high above the surface of the earth and another station which may be a submerged submarine. Position reporting by a laser transmission from the other station or submarine to the relay station provides for acquisition, tracking and data transmission between the stations. For strategic use transmissions to the submarine for one way data transmission is achieved by radio relay to the relay station and laser down link transmission to the submarine. Transponding mode operation is provided for a two-way transmission data link.

A secure communication system uses narrow beam laser transmissions between an orbiting satellite and another station which may be a submerged submarine. Position reporting by a laser transmission from the submarine to the satellite provides for tracking and data transmission between the stations. For strategic use tracking of the submarine for one way data transmission is achieved from a single laser transmission from the submarine while transporting mode operation is provided for a two-way transmission data link.

1. Apparatus for communicating with a mobile vehicle comprising means for transmitting a laser beam toward an orbiting satellite from a vehicle within the portion of the earth's surface beneath said satellite, means for detecting said laser beam received at said satellite to determine the angular orientation of said vehicle from said satellite, means for utilizing the angular orientation data so obtained to establish a narrow beam communication link from said satellite to said vehicle, and means for communicating with said vehicle from a remote point via said satellite and said narrow beam communication link.

This invention provides binocular eyeglasses that have linear polarizing lenses to be employed by a golfer to examine the surface of a putting green as an aid in deciding the speed and direction for a putting stroke. The planes of maximum transmission for the lenses are preferably complementary 45 to horizontal. A modified use and a modified embodiment provide for alternate angles of inclination relative to horizontal.
