Abstract: The invention is directed to an ornamental pond fish feeding indicator that has a housing with an indicator end. A first LED is enclosed in the housing at the indicator end of the housing. A second LED is also enclosed in the housing at the indicator end of the housing. A temperature sensing circuit is enclosed in the housing. The temperature sensing circuit transmits a signal to the first LED and the second LED. A float is attached to the housing. Using this invention, a pond owner can simply glance at his or her pond and determine whether or not to feed their fish based on the color of the light on top. The light on top of the indicator is red when pond water is below 50 degrees Fahrenheit. If the pond water is 50 degrees or over, the light is green.

Abstract: A light fixture (100) comprises a base (101) and at least a first arm (102) having a first end (103) that couples to this base. A housing (105) then couples to the second end (203) of this first arm and can serve to house both a light source (901) (such that emanated light will tend to be directed towards a primary area of coverage) and an animate object detector (902) (such that the latter will be aimed towards, and will tend to be sensitive to, objects that move within the primary area of coverage). By one approach, this arm couples to the base and/or the housing in a manner that permits an end user to adjust a position of the housing with respect to the base without requiring any hand tools. The housing can comprise a heat sink (906) if desired.
