Abstract: A multi-spectral imager useful for weather mapping, comprising an array of filters on at least one focal plane array (FPA) including pixels. Each of the filters are associated with a different set of the pixels, and each of the filters transmit a portion of electromagnetic radiation, comprising a different band of wavelengths, to the set of the pixels associated with the filter. A circuit connected to the pixels reads out a signal outputted from each of a plurality of different pixels in the set and outputs the signals to an adder. The adder sums the signals from each of the plurality of different pixels in the set to form a sum used for generating a weather map.

Abstract: A walk-behind lawn mower having a cord guide system for routing a recoil starter cord relative to a handle assembly of the mower. The guide system may include a cord guide operable to hold the starter cord to a non-interfering position such that a rear collection hopper can be easily removed from the lawn mower for dumping of collected grass clippings. The cord may be moved from the non-interfering position back to a starting position by application of a pulling force to the cord.
