Abstract: Methods for authenticating a genuine presence of a human involve directing one or more modulated probes towards a body part of the human, receiving a response to the probes from the body part, and analyzing the response to determine whether it contains spectral characteristics that match a class of responses to such probes for the human body part in a human population. Replay attacks are countered by varying the modulation of the probe temporally, spatially, and spectrally each time authentication is performed. The probes may include electromagnetic radiation, acoustic beams, or particle beams that generate a detected reflection, absorption pattern, scintillation, or fluorescence response of the body part. The analysis of the response may be directed to one or more of temporal, spatial, and spectral variations in accordance with the nature of the probes and the modulation.

Abstract: A user is guided to move a device equipped with an illuminator and a camera with respect to a document whose genuineness is to be assessed. The motion includes changing the distance between the device and the document by moving the device or moving the document. Imagery of the document is captured during the movement and analyzed to determine a likelihood that the document includes features indicative of genuineness, such as a hologram, an original photograph, and other regions matching those of a genuine document. The analysis may include identifying regions exhibiting large changes in appearance over relatively small distance changes which characterize holograms, and obtaining the spatial extent of document features.

Abstract: The dual tank beard care multi-tool disclosed herein is intended to be carried by a user and provide a mobile source of beard care grooming tools. The device provides two distinct tanks, one for oils and one for balms, and a plurality of tools required by beard wearers. Among these tools may be a switched beard comb, which may be manually or semi-automatically switched so that a user may carry the device without the comb teeth being exposed. The first tank and second tank may be integrated into the device main body or may be removably attached. The device may further comprise a plurality of receivers for receiving a folding comb, a scissor, and a beard brush. A mirror may also be installed within the device, and a heating element may be incorporated in some embodiments.

Abstract: Systems, methods, and computer program products provide near real-time feedback to a user of a camera-enabled device to guide the user to capture self-imagery when the user is in a desired position with respect the camera and/or the display of the device. The desired position optimizes aspects of self-imagery that is captured for applications in which the imagery is not primarily intended for the user's consumption. One class of such applications includes applications that rely on illuminating the user's face with light from the device's display screen. The feedback is abstracted to avoid biasing the user with aesthetic considerations. The abstracted imagery may include real-time cartoon-like line drawings of edges detected in imagery of the user's head or face.

Abstract: The system enables the observer(s) to record video and audio received from the remote location. The systems and methods enable the capture, storage, and management of metadata linked to the observation video and audio. The systems and methods enable communication between users and enables sharing of metadata. The systems and methods enable the immediate sharing of metadata and performance feedback between the observer(s) and the observed. The systems and methods also allow for delayed sharing of metadata and performance feedback. The systems and methods use technology to overcome the barriers of distance, enabling feedback that occurs in context, with high frequency, distributed over time and that is individualized. The system manages the presentation of all data types to the users. The system can also manage the scheduling of people and resources allocated to the systems and methods implementation.

Abstract: A method for reducing both reagent consumption and scale formation in a mineral separation circuit employing sulfoxy compounds as reagents. The method involves introducing into the mineral separation circuit a non-oxidizing gas in a quantity sufficient to reduce the degree of oxidation of the sulfoxy radical. Preferably the gas is introduced during the reagent conditioning and flotation stages, the stages where the presence of dissolved oxygen in a slurry is most likely to create the conditions conducive to oxidation of the sulfoxy radicals which result in reagent consumption and scale formation problems. The process is suitable for a wide range of mineral separation circuits which use sulfoxy reagents for the separation of sulfidic minerals including chalcopyrite, pentlandite, pyrite, sphalerite, pyrrhotite or galena.

Abstract: A process for recovery of a precious metals containing mineral from a non-sulphidic gangue mineral comprising:preparing a pulp of a material containing the precious metals containing and gangue minerals;conditioning the pulp with an oxidizing gas containing a gas selected from oxygen and ozone; andsubjecting the conditioned pulp to a flotation operation for recovery of the precious metals containing mineral.

Abstract: A process for recovering a secondary base metal mineral from a material containing it involving treatment of a pulp of the material with surface modifying reagent such as a water soluble sulphide. The pulp is subjected to deaeration by introduction of a non-oxidising gas to prevent oxidation of the reagent. The process is applicable to recovery of secondary minerals such as azurite, malachite, cerussite, anglesite and zinc ferrites from host materials.

Abstract: A flotation process for the separation of a mineral of non-sulphidic character, such as a talcose mineral, from a mineral of sulphidic character, for example a base metal sulphide, characterized in that a slurry containing a mixture of the minerals is subjected to a sequence of mineral dressing operations in which a non-oxidizing gas or gas mixture and a reducing agent are added to the slurry to maintain an electrochemical potential conducive to the separation of the minerals by flotation.
