Abstract: Sensors and methods for detecting attachment to a surface are disclosed. The sensors include a housing having an inner surface, an outer surface and a passage extending through the housing. An elongated member or fastener extends though the passage and protrudes from the outer surface of the housing to attach the sensor to a surface. First and second electrical contacts are disposed within the housing so that when the sensor is attached to the surface an electrical path is formed between the first and second electrical contacts.

Abstract: A security system having a frame with an upwardly facing support surface, a hanger for an article of clothing having a downwardly facing edge that can be placed against the upwardly facing support surface to thereby maintain the hanger in a display position, a cover, and first structure cooperating between the cover and the frame for mounting the cover for movement relative to the frame selectively between a) a first position wherein the hanger can be placed into and removed from the display position and b) a second position wherein the cover closely captively maintains the hanger in the display position.
