Abstract: A disclosed battery powered security monitoring system provides a security system that monitors validation signals detected by a sensor at least twice during each oscillation of the validation signal. This technique may be applied both while the main power to the gaming machine is on and while a backup power source (e.g., a battery) is on. Preferably, the security system of this invention employs a custom integrated circuit (e.g., an end-user programmed complex programmable logic device) to perform some the security functions such as supplying the validation signal to the sensor and comparing a sensor output signal to the validation signal to determine whether access to a gaming machine device has occurred.

Abstract: The present invention distinguishes door closing actions between the one effected when an object leaves a prescribed area (i.e. the door closing action resulting from “signal discontinuation due to the exit of an object”) and the one effected when an object remains stationary within the area for a certain period of time (i.e. the door closing action resulting from “forced signal discontinuation in the presence of a stationary object”). Regarding the latter case, the present invention protects a person who stops in the area, by setting the door to close at a low speed and/or issuing a vocal warning. This door closing action can reduce the risk of hitting the person with the door.
