Philip J. Ralli - Sudbury MA, US

International Classification:

G03B 21/56
H04N 9/31
G02B 5/20

Abstract:

A display screen includes a filter layer, a fluorescent layer having parallel fluorescent stripes, and an attachment layer between an excitation side of the fluorescent layer and a first side of the filter layer to attach the excitation side of fluorescent layer to the filter layer while providing vertical separation therebetween. The attachment layer includes attachment regions that are separated from each other by lateral spacings such that excitation-side air gaps are formed between areas of the fluorescent layer and the filter layer that correspond to the lateral spacings. During display operation, excitation light received on a second side of the filter layer propagates through to the first side of the filter layer, and at least a portion of the excitation light that propagates from the second side of the filter layer travels through the excitation-side air gaps to excite the fluorescent stripes.

Abstract:

A hand-warmer assembly and method of using the same. According to one embodiment, the hand-warmer assembly includes a hand-warmer and a leash connector. The hand-warmer may include a sleeve or a mitt having an open end for receiving a user's hand and a closed end. A pocket for holding personal effects may be provided on the exterior of the hand-warmer. A closure mechanism, such as a drawstring, may be provided to close the open end around the user's wrist or arm. The leash connector may include a strap and a clasp. The strap passes through the closed end of the hand-warmer, with a first end external to the hand-warmer and a second end within the hand-warmer. The first end of the strap is coupled to the clasp, which may be secured to a pet collar or leash. The second end of the strap forms at least one loop.
