Abstract: A method and system for obtaining orientation of a core sample core drilled from underlying rock. A core orientation recording device (116) records its orientation at random and/or non-predetermined time intervals from a reference time during a drilling operation. The time intervals are generated to be within a range of minimum and maximum time intervals. After a time interval elapsed from the reference time plus a wait time of at least the minimum random or non-predetermined time interval, the core sample is separated from the underlying rock and brought to the surface and its original orientation is determined from orientation data recorded closest in time to the elapsed time plus the minimum time interval. A remote communicator (160) having the elapsed time interrogates the core orientation recordal device (116) to identify the required orientation data and requires the core orientation recordal device to identify a correct orientation of the core sample.

If the degree of inclination is smaller than a predetermined threshold value, then the measurement data on a measurement point having a largest distance measurement value among the n number of measurement points is identified as noise data.

Abstract: A method is presented for estimating population from sample proportions that produces margins of error narrower for any specific sample size or that requires a sample size smaller for any specific margin of error than do previously existing methods applied to the same data. This method applies an unbiased estimator of the squared correlation between population and sample proportions to determine point and interval estimates of population proportions in a regression context involving simple random sampling with replacement. In virtually all reasonable applications, assuming a Dirichlet prior distribution, the margin of error produced by this method for a population proportion is shown to be 1.96 times the posterior standard deviation of the proportion.

Abstract: A battery monitoring system includes a current sensor and a voltage sensor coupled to a battery cell. It also includes a microcontroller that opportunistically computes many estimates of the cell's ohmic resistance and filters these estimates to arrive at a stable value. Each estimate is traditionally computed from a delta change in voltage divided by delta change in current measured before and after a significant change in current magnitude. An improvement in accuracy of each resistance estimate is achieved by only computing an estimate if the rate of change of voltage and the rate of change of current exhibited by the values making up the delta voltage and delta current are tightly consistent and of the same polarity. This approach significantly minimizes errors induced in estimates not preselected in this manner by the different and also asynchronous sample rates of the cell's voltage and current.
