Abstract: Methods and systems for determining whether a particular individual is to be granted, among other things, access to information, access to a particular room or other space, or permission to perform a given act or transaction are disclosed. For example, disclosed is an exemplary method that includes performing multiple biometrics tests on the individual to retrieve multiple biometrics test results, performing at least a first data fusion operation on the multiple biometrics test results to determine an identity result, performing at least one biological state test to determine one or more biological state test results of the individual, and conditionally granting authority to the individual based on the identity result and the one or more biological state results.

Abstract: An alarm adapted to be mounted on an object to be protected is provided with sensing means for sensing any one of (a) a movement of the protected object, (b) a disruption of an applied voltage source, and (c) a disruption of an alarm ground path. The alarm is further provided with signal generating and timing means to produce a two-frequency alarm signal for a selectable length of time.
