Abstract: A method for configuring a calibration mechanism in a force sensor (100) has the steps of: coupling an end of the calibration lever (1071) to a loading end (102) of the force sensor; adjusting, in a no-load condition, the center of gravity (G0) of the unloaded calibration lever (1071), so that the center of gravity (G0) lies on a horizontal line (H) through the center of a calibration lever fulcrum (1031) at a fixed end (103) thereof; and adjusting, in a full-load condition, the center of gravity (G1) of the calibration lever (1071) loaded with the calibration weight (106), so that the center of gravity (G1) lies on the horizontal line (H) through the center of the calibration lever fulcrum. The calibration error caused by inclination in the force sensor is reduced by practice of this method.

Abstract: Techniques for detecting instances of external fraud by monitoring digital activities that are performed with accounts associated with an enterprise are disclosed. In one example, a threat detection platform determines the likelihood that an incoming email is indicative of external fraud based on the context and content of the incoming email. To understand the risk posed by an incoming email, the threat detection platform may seek to determine not only whether the sender normally communicates with the recipient, but also whether the topic is one normally discussed by the sender and recipient. In this way, the threat detection platform can establish whether the incoming email deviates from past emails exchanged between the sender and recipient.

Abstract: A computer implemented method for managing datasets for a histogram. The method uses a number of processor units to determine a first span for first bins containing first datapoints in a first dataset in the datasets. The first span is determined based a distribution of the first datapoints in the first dataset and a desired number of bins. The number of processor units adjusts a second span for second bins containing second datapoints in a second dataset in the datasets to form an adjusted span that matches the first span for the first bins. The number of processor units merges the first datapoints in the first bins having the first span with the second datapoints in the second bins having the adjusted span to form a merged dataset for the histogram.

Abstract: A device is described that performs an image processing technique. The device includes a first camera and a second camera, which are responsive to distinct spectra of light, such as the visible light spectrum and the infrared spectrum.
