Title: Iris acquisition using visible light imaging
Inventor: Lawrence A Willis
IPC: G06V10/143
Filed: 2016-03-29
Abstract: A method, device and system for iris acquisition using visible light imaging are claimed, suitable for use when a user is wearing spectacles. The method comprises steps of determining that a user of a mobile device is wearing glasses 208 using ambient light or projected visible light and determining the centre point 222 of a lens of the glasses. Near infra-red light (NIR) 204 is projected to illuminate at least one eye of the user ensuring it encompasses the determined centre point of the lens effective to illuminate the pupil 228 of the eye. The pupil of the eye is located based on a reflection of the NIR light from the pupil at approximately the determined centre point of the lens. The determination of the centre point and location of the pupil based on reflection of infra-red light may occur approximately simultaneously. An IR imager 108 may be activated to capture an image of the pupil for iris authentication. An alignment indicator 122 may be displayed on the mobile device to show the direction to turn the device for alignment. The device and system include LEDs 106 for NIR lighting.

Title: Method for computational fluid dynamics and apparatuses for jet-effect use
Inventor: YURI ABRAMOV
IPC: F03D80/00
Filed: 2016-06-07
Abstract: A convergent-divergent nozzle 610 is defined with a specific shape, claimed to provide linear change in Mach number, pressure, temperature or density, for more efficient acceleration of a fluid. The nozzle may be real or imaginary, defined by streamlines in the fluid flow, caused by aerofoils of limited extent. Described uses for the nozzle include propulsion for a flying saucer which does not require fuel, and systems which, in addition to producing thrust, also provide low temperature air. The nozzle is also described with powered, contra-rotating propellers for propulsion or fluid extraction. The application also describes a proposed hydrophobic jet effect produced by specifically shaped, hydrophobic bodies. Also described is a method for computational fluid dynamics which claims to be based on the kinetic theory of matter, thermodynamics, continuum mechanics, and generalized equations of fluid motion. Methods can be applied to airfoil shape optimization for bodies flying separately as well as in a cascaded sequence. Water harvesting from air is also discussed.

Inventor: JASON MAROOTHYNADEN
IPC: H04M7/00
Filed: 2016-11-30
Abstract: Peer-to-peer selective streaming for a collaboration session between peer computing devices of a plurality of users via a server which receives multiple information sources from one or more of the peer computing devices, and simultaneously broadcasts the multiple information sources to other peer devices in the collaboration session over a communication network. In addition to shared information source streams 114, each peer computing device of a user also transmits a user information source stream 118 representing an information source of the user captured by the peer computing device, which are also streamed 120 to peer computing devices of users in the collaboration session. Although the users of each of the peers may be in the same virtual "room" or common space, not every user may receive the same information sources/streams. The information sources may include video, audio, multimedia, data representative of files or documents, or any other information source representing information that a user of a peer device may select for transmission to other peers in the collaboration sessions. Thumbnails of shared information source streams may be presented 120 on a peer device which are selectable and selection results in an enlarged view of that stream being displayed 122.

Title: Handheld dimensioning system with feedback
Inventor: FRANCK LAFFARGUE
IPC: G06T7/62
Filed: 2015-09-28
Abstract: Handheld dimensioning system comprising receiving range data, creating depth map from range data, processing depth map to determine its quality and generating error feedback if depth map quality is below quality threshold. Depth map quality may be null-data pixel count of pixels having insufficient information to determine depth. Depth map quality below threshold may be when null-data pixel count is above threshold count. Error feedback may indicate a colour is too dark or insufficient lighting. Confidence feedback may be displayed, with indication of standard conformation. User-guidance feedback may facilitate measurement geometry or lighting adjustment. Structured light pattern may be used for dimensioning. Logistics and shipping companies need to compute package volume to facilitate storage, handling, transporting and/or invoicing because vehicles have volume and weight capacity limits and space inefficiencies result if vehicle is full before its weight capacity is reached. Dimensioning system environments can be harsh because of lighting and object positioning / colouring issues. This invention involves hands-free measurement of object volume with feedback minimising dimensioning errors.
