Abstract: A method and device for providing one-step payment approval and confirmation are disclosed. The device concurrently displays a data entry region and a confirmation region in a user interface of the device, where the data entry region is to accept user entry of payment data associated with a payment operation and the confirmation region is to require a sliding input to cause execution of the payment operation. While displaying the data entry region containing payment data received from a user, the device detects a user input in the confirmation region of the user interface. The device determines, in accordance with a predetermined criterion, whether the detected user input qualifies as a sliding input that follows a predefined motion path. Upon determining that the detected user input qualifies as the required sliding input, the electronic device executes the payment operation in accordance with the received payment data.

Abstract: Described herein is a method and system for characterizing in-ground rock types from measurement-while-drilling data in a mining environment. The method includes the steps of drilling holes at a plurality of selected locations within a region of interest; collecting measurements while drilling to obtain an array of data samples (162) indicative of rock hardness at various drilling depths in the drill hole locations; obtaining a characteristic measure (163) of the array of data samples; performing Gaussian Process regression (164) on the characteristic measure; and applying boundary detection (166) to the rock hardness output data obtained from the Gaussian process model to identify the distribution (280) of at least one cluster of rock type within the region of interest.
