Abstract: A system for the online sorting of ore samples based on mineralogy analysis includes a conveyor moving a stream of the ore samples along a conveying path, a LIBS module, a height measuring device, a focus controller and an airflow system. The LIBS module projects a LIBS laser beam along an optical path focused on an analysis spot of dimensions of the order of one or a few mineral components of the ore samples, and collects a returning LIBS light signal. The height measuring device and focus controller collaborate to adjust in real-time the focus of the LIBS laser beam to move the analysis spot perpendicularly to the conveyor according to a height of the ore samples crossing the optical path. The air flow system moves particles away from the optical path. A processing unit performs the mineralogy analysis of the ore sample based on the LIBS light signal.

Abstract: Example data leakage detection apparatus disclosed herein include a fingerprinter to generate a first data fingerprint of a first data item accessed from a data source. Disclosed example data leakage detection apparatus also include a blockchain scanner to scan a blockchain to detect whether a first blockchain record includes a second data fingerprint that matches the first data fingerprint of the first data item. Disclosed example data leakage detection apparatus further include a blockchain writer to write a second blockchain record to the blockchain when the second data fingerprint matches the first data fingerprint, the second blockchain record to indicate the first data item is associated with a data leak of a protected data item represented by the second data fingerprint. In some examples, the second blockchain record is to include the first data fingerprint and a first timestamp.

Abstract: In one embodiment, an apparatus includes an interface and a queue generator. The interface obtains a plurality of submissions associated with a conference call. The submissions include at least one text-based submission and at least one audio-based submission. The queue generator manages a queue that has representations of at least some of the submissions, and is accessible to a speaker associated with the conference call. The representations include a first representation of the text-based submission and a second representation of the audio-based submission.
