Patent ID: 7505374

Claim:
An integrated electronic timer-clock comprising (A) a housing; (B) a face mounted in said housing; (C) an analog display comprising a plurality of circumferentially placed, spaced apart symbols on said face; (D) at least one hand continuously moving along a circular path past said symbols to indicate one of a group consisting of hours and minutes; (E) an electronic control unit mounted in said housing and operatively associated with said face to produce said analog display on said face, said control unit having at least two operative modes, (1) a first operative time-of-day mode with a spaced apart first group of circumferentially placed symbols ( 314 ) formed on said face, used to indicate the time-of-day and including (a) an hours track with a plurality of radial segments ( 281 , 282 , 283 ) that sequentially cumulatively illuminate or de-illuminate to indicate the hours of time that have passed such that during the majority of times of day a plurality of said radial segments are illuminated and (b) a minutes track concentric with said hours track and with a plurality of radial segments ( 316 , 317 , 318 , 319 ) separate from said hours track and that sequentially cumulatively illuminate or de-illuminate to indicate the minutes of time that have passed such that during the majority of times of day (i) a plurality of said radial segments of said minutes track are illuminated, and (ii) a proportion of said minutes track is illuminated that is different from the proportion of said hours track that is illuminated; and (2) a second operative timer mode with a spaced apart second group of circumferentially placed symbols ( 214 , 994 ) formed on said face, different from and replacing said first group of indicia, and used as a timer to indicate the passage of a selected period of time and not to indicate the time of day, said second group of indicia including a radial track with a plurality of radial segments that sequentially cumulatively illuminate or de-illuminate to indicate time that has passed such that during the greater portion of said selected period of time at least a plurality of said radial segments of said radial track of said second group of indicia are illuminated.
