The controller places the first transceiver and the second transceiver in a low-power mode when no transmissions are expected from the base unit or from the sensor units listed in the sensor identification table.

Alignment accuracy between two or more patterned layers is measured using a metrology target comprising substantially overlapping diffraction gratings formed in a test area of the layers being tested. An optical instrument illuminates all or part of the target area and measures the optical response. The instrument can measure transmission, reflectance, and/or ellipsometric parameters as a function of wavelength, polar angle of incidence, azimuthal angle of incidence, and/or polarization of the illumination and detected light. Overlay error or offset between those layers containing the test gratings is determined by a processor programmed to calculate an optical response for a set of parameters that include overlay error, using a model that accounts for diffraction by the gratings and interaction of the gratings with each others' diffracted field. The model parameters might also take account of manufactured asymmetries. The calculation may involve interpolation of pre-computed entries from a database accessible to the processor. The calculated and measured responses are iteratively compared and the model parameters changed to minimize the difference.

Systems and methods utilized a wireless transceiver (5008) having a low power radio frequency (LPRF) component (5010) that powers down to conserve energy and powers up in response to a signal; and a second receiver (5014) that provides the signal via line (5018) in response to receipt of a radio frequency broadcast.

A transceiver may include one or more identifications and may include a unique identification of the transceiver itself. The LPRF component may be a Bluetooth radio, but in such case the overall transceiver itself only draws about 10 to 15 μA while actively awaiting and screening for a targeted broadcast.

An ad hoc emergency interoperability communication network is established by providing universal temporary incident area network modules that communicate with each other on an open network, with the network being established when vehicles containing the temporary incident area network modules are within range of each other.

A method of forming an ad hoc hierarchical communication network among a plurality of wireless transceiver includes assigning to each of the transceivers one or more common designations. A network organization routine of the transceivers operates to establish hierarchical networks based on the transceivers' common designations, resulting in a logical network organization that provides efficiencies for acquiring information from particular transceivers that share a common designation. Each transceiver's common designation is used by a digital processor of the transceiver to selectively receive data packets that are intended for receipt by transceivers sharing the particular common designation. Such a “common designation” network reduces power consumption and signal interference, which increases battery life in the transceivers. The transceivers may include a query handling routine in communication with a memory of the transceiver for serving as a dynamic distributed hierarchical database system of information such as, for example, sensor-derived information and time-sensitive information.
