safety device for checking the vigilance and geographical game for use in this device.

摘要

A safety alertness monitoring system is provided for maintaining an operator alert. A switching means is provided which must be actuated by the operator within an adjustable time period to prevent a first alarm from being activated. Upon detection of this first alarm, the driver must actuate the switching means, indicating his alertness and restarting the first time period, otherwise after expiration of a second time period a second alarm will be activated to further alert the operator and passengers. This second alarm will remain activated until the switching means is actuated restarting the process. The present invention also includes a waiting mode whereby the timer can be deactivated while driving in congested traffic. During the waiting mode, a third alarm is activated to provide some alerting function. The device also includes a first electrical output which is usually ON, but is turned OFF when the buzzer sounds. This output can be used to supply power to, for example, games for the enjoyment of children. Since the driver in effect "controls" the power supplied to the first output, additional interaction of passengers with the driver is ensured, thus further raising the alertness of the driver. Additionally, an entertainment/educational game is provided which teaches players thereof about geography. The safety alertness monitoring system can be used as a timer with the game. The game includes a playing surface having a geographical area divided into subregions illustrated thereon, the geographical area and subregions having geographically significant shapes. A plurality of elongated, flexible members (e.g., colored strings) having fixed, equal lengths are provided as playing pieces, one for each player (or team). An object of the game is to accumulate points while attaching ones playing piece to the playing surface within subregions to achieve some predefined goal (e.g., extending one's playing piece across the geographical area or forming a loop with one's playing piece), while attaching one's playing piece to at least a minimum number of subregions. Players draw cards which include indicia corresponding to one of the subregions. Players attach a portion of their playing piece to the playing surface within a subregion if they can locate the subregion within a preset time period. Players accumulate points by identifying the subregions on the playing surface and by reciting additional information about the selected subregion (e.g., if the subregion is a state or country, by reciting the capital of the state or country) also within the preset time period. When played within an automobile, the operator can actuate the timer, which assists in maintaining a level of alertness in the operator. IMAGE
