In one embodiment, a system includes an interface and a communicatively coupled processor. The interface is configured to receive first future location information of a first user and receive second future location information of a second user. The processor is configured to determine that the first and second future location information each correspond to a future location and determine that a characteristic related to the first user corresponds to a preference related to the second user. In response to these determinations, the processor is configured to cause information to be presented to the second user, the information to be presented to the second user comprising the future location and that the first user and the second user have the future location in common.

A system comprises a portable device, a plurality of sound sensors installed in the portable device, an alarm element installed in the portable device, and a controller coupled to the plurality of sound sensors and the alarm element. The controller receives a signal indicating a sound detected by at least one of the plurality of sound sensors, determines whether the sound indicates the presence of a potentially hazardous event, ascertains the direction of the sound based on the received signal indicating the sound, activates the alarm element if the sound indicates the presence of the potentially hazardous event, and does not activate the alarm element if the sound does not indicate the presence of the potentially hazardous event.
