The data interpretation unit may query a database to determine the product grade of the electronic product based on the sensor data and to determine an estimated product value. The data interpretation unit may query a database to determine an estimated warranty cost of an extended warranty based on the condition of the electronic product and historical warranty value.

A method for trading securities including options. A trader generates a variable derivative product order that identifies at least a derivative product, an underlying financial product or instrument, a pricing formula, and values of price determination variables needed by the pricing formula to establish a price for the derivative. The variable product order is transmitted electronically to an exchange. The exchange calculates the offered price of the derivative using a value of the underlying product and publishes offers to potential traders. The offered price is recalculated as the value of the underlying products changes and republished to potential traders. Trades may then be executed based on the offered prices. Hedging trades may be executed in combination with trades made based on the variable derivative product orders.

A leakage detecting apparatus includes a re-circulating passage for re-circulating an exhaust gas from an exhaust system to an air intake system in the engine, a re-circulating valve disposed in the re-circulating passage to control a flow rate of the re-circulating exhaust gas, and an A/F ratio sensor for detecting an A/F ratio of the exhaust system. An electronic control unit detects an operation amount of the re-circulating valve and calculates correlation between the operation amount and output of the A/F ratio sensor to determine a leakage in the re-circulating passage. The correlation is obtained by an inner product calculation of a vector of deviations of a time-sequence vector of the operation amount relative to a moving average and a vector of deviations of a time-sequence vector of the output of the A/F ratio sensor relative to a moving average. Leakage in the re-circulating passage is detected when an accumulated value of the inner product values over a predetermined period exceeds a threshold value.

The present invention provides a method for avoiding rounding errors during rounding of values after performing an inverse discrete orthogonal transformation. In a first step, a block of coefficients (F′[u][v]) is transformed into a block of image pixel values (f′[y][x]) by means of an inverse discrete orthogonal transformation, wherein each image pixel comprises an image pixel value. In a second step, a product of the block of image pixel values (f′[y][x]) with a first pixel pattern (A[y][x]) is calculated. In a third step, the product values of the second step are summed up to a first sum (Sum1′). In a fourth step, it is determined whether the first sum (Sum1′) is even or odd. In a fifth step, if the first sum (Sum1′) is even, a block of manipulation values (C[y][x]) is added to or subtracted from the block of image pixel values (f′[y][x]) for generating a manipulated block of image pixel values (f[y][x]), wherein the block of manipulation values (C[y][x]) is formed in such a way that rounding errors are avoided in a subsequent rounding operation.
