Abstract: A latch mechanism, which is coupled to a window sash that travels within a window frame, is adapted for being coupled to a pocket brace, which extends across the channel opening of the jamb pocket of the side jamb. The latch mechanism includes a main housing, a bolt, and a tension device. The main housing has a sidewall, which includes one or more sidewall sections which extends around at least a portion of the housing and defines an interior space, and has an opening in said sidewall at one end of said housing. The sidewall forms a channel within the interior space of the main housing having an end that coincides with said opening. The bolt is substantially located within the housing and travels along the channel, and has a first end which is adapted for extending through the opening of the housing and extending into the side jamb of a window frame. A first end of the bolt has a protrusion, which projects in the direction of travel of the window sash within the window frame.

Abstract: The present invention provides a method and apparatus for generating time of arrival estimates for use by a wireless communication network for locating the position of a wireless or mobile source (102) within the service area of the wireless communication network. The mobile source generates time of arrival estimates from data bursts received from base sites (100) operating within the network. In at least one embodiment, the mobile source (102), then, communicates the time of arrival estimates for each of the base sites (100) to the network, from which the location of the mobile source (102) is determined. In at least some instances, the mobile units additionally determine a variance estimate for each time of arrival estimates, which is representative of the degree of confidence in the time of arrival information being supplied to the network.
