Abstract: A method and an assembly for sensing moisture (20) on the exterior surface (22) of a sheet of glass (14) by positioning an imaging lens (16) adjacent to the interior surface (18) of the sheet of glass (14), passing light rays from moisture (20) on the exterior surface (22) of the sheet of glass (14) through the imaging lens (16) and producing first and second successive images of the moisture (20) on the glass (14), and successively directing the first and second images from the lens (16) onto a focal plane detector (12). The focal plane detector (12) is divided into rows of pixels (24) which are ligned into columns. The assembly and method are characterized by scanning the pixels (24) of each row in a first scan (FIG. 4) and producing a reference value X for each pixel (24) in response to an initial image in that pixel (24), scanning the pixels (24) of each row in a second scan (FIG.

Abstract: A local video game (310) including a communicating controller (326). The controller (326) receives local command signals created by a set of player controls (316). The controller (326) also receives remote command signals received through a modem (324) which were created by a remote video game (320) through a similar set of player controls. The controller (326) includes a synchronizer (328) which produces synchronizing codes to be sent to the remote video game (320) to synchronize the games. The synchronizer (328) synchronizes the local and remote command signals such that both are received by a game microprocessor (322) simultaneously. Memory (336) stores the player parameters and are retrieved whenever the synchronization codes of the local (310) and remote (320) video games have not matched for a predetermined number of iterations.
