Title: Aerial vehicle with fender cage rotatable about two perpendicular axis
Inventor: ANDREW NORMAN MACDONALD
IPC: A63H27/00
Filed: 2016-01-25
Abstract: An aerial vehicle has a lift assembly and a fender cage that can rotate about two mutually perpendicular axes. The fender cage is supported by an endless annular track 14 in which a rotary bearing is engaged that connects the lift assembly to the track. This permits rotation of the lift assembly about axis L. The fender cage has opposing hubs 15. Within these are rotary bearings that allow the fender cage to rotate about a second axis H, perpendicular to the first.

Title: Method and apparatus for synchronizing auto exposure between chromatic pixels and panchromatic pixels in a camera system
Inventor: BY-HER RICHARDS
IPC: H04N9/04
Filed: 2016-09-06
Abstract: Method/apparatus to synchronize auto-exposure between chromatic (R,G,B-fig1) and panchromatic pixels (P-fig1) in a single or multi-camera system (110-fig1). An exposure 930 is determined for different chromatic pixels which detect different colour (R,G,B chromatic) light. The type of illumination for a particular scene 940, for example sunlight, shaded light, tungsten, is detected (e,g white balance algorithm). An exposure ratio 950 between chromatic and panchromatic pixels is then determined based on the determined illumination type. A different exposure is ascertained 960 for the panchromatic pixels which detect panchromatic (monochromatic, white, clear, unfiltered) light. Images of the scene may then be captured 970 and the images generated 980-990 using the exposure for the different chromatic pixels and the second exposure for the panchromatic pixels. The chromatic pixel exposure time may be longer in time than that of the chromatic pixels. The exposure ratio may equate to either an un-weighted or a weighted ratio of received light in the chromatic and the panchromatic pixels, and for a given light source in an illuminated scene. Weighting may be based on the relative percentage of the number of pixels present for each colour of the chromatic pixels and the relative number of the panchromatic pixels. The pixel received light is based on a summed area of a product curve of a spectral response of colour channel pixels, spectral response of the illuminated scene and a transmittance of an infra-red cut-off filter. The sensor gain may be the same for the chromatic and panchromatic pixels and chromatic and panchromatic pixel exposure times based on first and second exposures respectively. Alternatively the same exposure times may be set for the chromatic and panchromatic pixels whilst the sensor gain for each pixel type may vary dependent on the first and second exposures. The chromatic and panchromatic pixels may be associated with different sensors or same sensors and also associated with the same camera or two different cameras in which case the instantaneously captured images are combined. The apparatus may further comprise one or more camera units, a lens a controller and a sensor (figure-1).

Title: Method and apparatus for dynamic location-based group formation for a movable incident scene
Inventor: ALEXEI VLADIMIROVICH IGUMNOV
IPC: H04W4/10
Filed: 2014-03-24
Abstract: ﻿Dynamic location-based group formation is provided for a movable incident scene (MIS) in a wireless radio communication system comprising a plurality of first subscriber units. A controller receives, from a requesting device, a request for a new group call for a MIS. The controller receives an initial location associated with the MIS and an indication of a speed and direction of travel of the MIS, and then determines one or more potential future locations of the MIS. The controller identifies a set of one or more inclusion threshold rules for each of the one or more potential future locations, and forms a location-based group including first subscriber units meeting at least one inclusion threshold rule for any one of the one or more potential future locations. The controller causes audio and/or data transmitted by the requesting device to be provided to the first subscriber units in the formed group.

Title: Motion vector reference selection through reference frame buffer tracking
Inventor: YUXIN LIU
IPC: H04N19/52
Filed: 2016-12-19
Abstract: Encoding or decoding a video signal includes storing 602 a reference frame identifier with a reference buffer index for each of a plurality of reference frames after encoding a first frame and updating 604 a reference frame associated with one of the identifiers after the storing. Multiple candidate motion vectors are determined 606 for a current block, the candidate motion vectors including a first motion vector used to predict a co-located block within a first frame. A reference buffer index stored with a frame identifier associated with the first motion vector can be compared 610 to a reference buffer index of a reference frame used to predict the current block of a second frame. On the condition that the reference buffer indices of the frames match, the first motion vector is advanced 614 ahead of remaining ones of the plurality of candidate motion vectors for encoding or decoding the current block. The first motion vector may be used as a motion vector predictor.

Chat device 1001 encodes a message to be sent using the Unicode cipher table with the hash value and sends it to the chat server 1005. Chat device 1002 receives the Unicode cipher table and obtains a decryption key from the homomorphic key server. Chat device 1002 obtains the message from the chat server 1005 and decodes the message without requiring the hash value. The hash value may be generated from keywords sourced from a conversation using a machine learning algorithm. The hash used may be derived from the word with the maximum influence on subsequent words.

Title: Methods and apparatuses for deriving wellbore fluid SAG from thermal conductivity measurements
Inventor: DALE E JAMISON
IPC: G01N25/18
Filed: 2014-12-19
Abstract: Thermal conductivity measurements of a wellbore fluid may be used to derive the sag of the wellbore fluid (i.e., the inhomogeneity or gradation in particle distribution in the fluid as a result of the particles settling). For example, a method may include measuring a thermal conductivity of a fluid at two or more locations along a height of a vessel containing the fluid that comprises particles dispersed in a base fluid; and calculating a sag of the fluid based on the thermal conductivity at the two or more locations. In some instances, the temperature and pressure of the fluid may be changed and/or the fluid may be sheared to investigate their effects on sag.
