An acoustic wave device is provided comprising a substrate and at least one resonator structure of a first type and at least one resonator structure of a second type mounted on the substrate. The resonator structures of the first type are configured to operate as capacitors and have a first thickness, causing the resonator structures to have a first passband frequency range. The resonator structures of the second type have a second thickness that is different from the first thickness, causing the resonator structures to have a second passband frequency range. A method for forming such an acoustic wave device is also provided. A die comprising such an acoustic wave device, a filter comprising such an acoustic wave device, a radio-frequency module comprising such an acoustic wave device, and a wireless mobile device comprising such an acoustic wave device are also provided.

A system and method for monitoring a vehicle uses a wireless mobile device. The wireless mobile device, such as a cell phone, smart phone, PDA, etc., includes some of the hardware that could be utilized to monitor and analyze data and transmit the data (or summaries, statistics or analyses of the data) to a central server. This can greatly reduce the overall cost of the system. The data can be used to determine an insurance rate or as a speed probe for creating traffic maps, for example.

Techniques for coordinating a frame of reference between wireless devices may comprise determining a displacement vector of a wireless mobile device with respect to its local coordinate system, the displacement vector indicative of a displacement of the wireless mobile device between a first time and a second time. Techniques may further comprise the wireless mobile device receiving, from a first wireless reference device, an indication of a displacement vector of the wireless mobile device with respect to a common reference direction, and adjusting an estimated alignment of the common reference direction with respect to the wireless mobile device's local coordinate system, based at least in part on correction information determined from a comparison of (i) the displacement vector of the wireless mobile device with respect to its local coordinate system with (ii) the displacement vector of the wireless mobile device with respect to the common reference direction.

A method and system for generating an aircraft cockpit display for a mobile device has been developed. First, a graphical data display is generated on a cockpit display system (CDS) of an aircraft during flight operations. The CDS uses an Aeronautical Radio, Inc. (ARINC) display architecture standard. A duplicate of the graphical data display is transmitted to a wireless mobile device located onboard the aircraft. The duplicate of the graphical data display is then displayed on the wireless mobile device.
