摘要： A method and system for evaluating geophysical survey data is provided. Two neighboring flight paths of a geophysical survey are likely to have geophysical characteristics in common because neighboring flight paths cover geographic areas in a close proximity to one another. As such, neighboring flight paths will likely have similar geophysical characteristics and similar recorded data. Therefore, errors in data can be estimated by comparing data recorded from neighboring flight paths. If data from a flight path differs significantly from data recorded from a neighboring flight path, then the data from one or both flight paths may be corrupted and at least one of the survey lines may need to be repeated. This auto evaluate method allows field personnel to judge data close to real time to determine whether to repeat a flight path while still out in the field.

摘要： An OFDM wireless communication system with an access point and a plurality of remote user terminals estimates an uplink channel. The access point receives training symbols transmitted by the user terminals. Each training symbol includes pilot symbols associated with phase offset estimation OFDM sub-carriers. The phase offset estimation sub-carriers include subsets of sub-carriers associated with each respective user terminals. Each subset is used exclusively by the associated user terminal during channel estimation. The channel estimation sub-carriers are used by all user terminals. For each terminal the access point estimates symbol-specific phase offsets specific to the user terminal using the received pilot symbols associated with the user specific subset of the phase offset estimation sub-carriers. The access point also estimates the uplink channel using the user-terminal-symbol-specific phase offset estimates and the received symbols.

摘要： Disclosed is a method of measuring time of arrival of a signal transmitted from a transmitter (120) to reciever (110-n). The method comprises: modulating a plurality of narrowband signal portions onto different carrier frequencies; transmitting by the transmitter, each modulated signal portion to the receiver; receiving, by the receiver, the transmitted signal portions; estimating the channel impulse response by combining (610) the received signal portions; and measuring (620) the time of arrival using the estimated channel impulse response. Further disclosed is a method of measuring a time of arrival of a signal transmitted from a transmitter to a receiver. The method comprises: estimating a noise level (1310) in an impulse response of a channel between the transmitter and the receiver; finding a first peak (1330) in the channel impulse response that is not noise or a side lobe of a subsequent peak, using the estimated noise level; and measuring the time of arrival (1220) using the first peak.

摘要： An electrical component includes a conductive substrate, a tin layer formed on the substrate, and a multi-phase coating formed on the tin layer to impede tin whisker growth. The multi-phase coating comprises a polymer matrix having pores dispersed therethrough, with the pores constituting at least 30% by volume of the coating. To form the multi-phase coating, the tin plating or finish is covered with a coating comprising a polymer matrix having a second material mixed therein. The second material is subsequently removed from the polymer matrix to produce a coating having pores in the matrix where the second material was disposed before being removed.
