Abstract: A device includes an image sensor, first optics, second optics, and a processor. The first optics are configured to form a first optical pattern (OP) on the image sensor. The first OP is associated with a first wavelength. The second optics are configured to form a second OP on the image sensor. The second OP is associated with a second wavelength that is longer than the first wavelength. The processor is configured to generate a first turbulence estimate based on relative motion of the first OP, to generate a second turbulence estimate based on relative motion of the second OP, and to generate error correction data. The processor is also configured to adjust the first turbulence estimate based on the error correction data and the second turbulence estimate to determine an estimated turbulence value. The processor may also be configured to estimate a wind profile, a turbulence profile, or both.

Abstract: A communication system comprises a mobile unit that generates mobile unit position signals and message signals. A base station is wireless two-way coupled to the mobile unit. The base station has a GPS receiver that generates base station position signals, a master wireless modem that receives the mobile unit position signals, and the mobile unit message signals. The base station includes a base display changing in response to the mobile unit position signals and the base station position signal.

Abstract: The present invention is directed to devices, systems, and methods for intelligent or ‘smart’ exercise equipment to indicate the location, the intent to use, and/or the amount and/or type of use of a piece of exercise equipment. More specifically, one embodiment of the invention may be used to locate or indicate the location of a portable piece of exercise equipment. Such an indicator may also indicate to other users, a particular user's intent to use the piece of equipment such that other users will not attempt to use the equipment or the current user may end their use of the equipment and pass it to the intended user. In a further embodiment, the indicator may not be activated if the piece of exercise equipment is already in use by a current user. In another embodiment of the invention, the amount of use of, e.g., repetitions done on, a piece of exercise equipment may be indicated to the user or may be logged for later viewing, downloading, or transmission.
