Abstract: The present disclosure relates to systems and methods for guiding emergency personnel to a location in a facility proximate to an alarm that has been generated. In one aspect, a method may include detecting an alarm condition at a facility protected by a security system and determining a location at the facility of the alarm condition. The method may further include causing at least one indicator at the facility, which is proximate to the determined location of the alarm condition, to generate an identifying alert that is humanly perceivable from an exterior of the facility such that emergency personnel can identify the facility based at least in part on the identifying alert. In some aspects, the method may also include notifying a security representative of the alarm condition, and receiving a notification from the security representative indicating that emergency personnel are dispatched to the facility.

Abstract: A selectively removable module, such as a PCMCIA card, inserted into a host computer system, such as a notebook computer, is provided that has a electrical interface between the module circuitry and the host computer circuitry, A wireless data channel is implemented between the module circuitry and the host computer system circuitry that is independent of the electrical interface. This wireless communications channel is implemented entirely within the confines of the external housing of the host computing system. One embodiment uses an infrared LED or emitter to transmit infrared signals from the module circuitry to an infrared sensitive phototransistor located within the host and electrically connected to the host circuitry.
