Abstract: The subject invention provides a method of allowing access to an electronic device (218) disposed in a working space (14) by a user (16) having a remote device (212). An initial signal is transmitted from an access point (20) instructing the remote device (212) to respond after a delay period. The remote device (212) responds upon the expiration of the delay period. The access point (20) measures a period interval from the transmission of the initial signal to the detection of a response signal. A distance of the remote device (212) is determined based upon the period interval and the known positions of the access point (20) and the electronic device (218). In another embodiment, a fixed device (256) transmits locating signals detected by three access points (220, 221, 223) and the access points (220, 221, 223) measure a time differential. The position of the remote device (212) is determined based upon a time of arrival, the location of each of the access points (220, 221, 223), and the time differential.

Abstract: A chime cover assembly (10) comprising a box-like housing for supporting the electrical components of a door chime and including a cover (12) presenting a front wall (18) and a base (14) for mounting to a wall (16). The assembly characterized by a decorative plate (30) for being covered with wallpaper (32), or the like, and secured to the front wall (18) of the cover (12). The front wall (18) has holes (34) therein and the plate (30) includes integral projections (36) extending therefrom for insertion into the holes (34) for securing the plate (30) to the front wall (18). The cover (12) presents slanted trim areas (44) at the top and bottom of the front wall (18) and trim strips (46, 48) attach to the housing in the trim areas (44).
