Abstract: A first mobile station (102) can be wirelessly linked to a second mobile station (104). A physical location of the second mobile station with respect to a physical location of the first mobile station can be determined. A first player (112) using the first mobile station can be presented an icon (402) representing a second player using the second mobile station. The icon can be presented from a perspective of an eye level view. At least one targeting icon (410) can be presented to the first player to facilitate targeting of the second player. A physical stimuli can be generated from the first mobile station and/or the second mobile station in response to a simulated weapon activation on the first mobile station. The physical stimuli can be a narrowly focused ultrasound beam (302) modulated to generate an audible sound when a propagation of the ultrasound beam is disrupted by a physical object.

Abstract: A method for periodically removing water from cathode flow channels in a fuel cell stack that includes looking at the resulting cell voltage patterns in response to selectively pulsing the cathode airflow during. If the fuel cell stack has been in an extended low power condition for a predetermined period of time, the cathode airflow is pulsed, and the output voltage of each cell is measured to determine the difference between the cell voltages. If the cell voltages significantly vary, then the cathode airflow is pulsed more frequently, and if the cell voltages cells are sufficiently close, then the cathode air is pulsed less frequently. The propose water management diagnosis can be used in a control system to determine the frequency of cathode air pulsing.
