Title: Method for acquiring geophysical data by dynamically manipulating survey spread
Inventor: MICHAEL MALLING
IPC: G01V3/17
Filed: 2016-02-11
Abstract: A target 170 for a marine geophysical survey system is located beneath a bottom 165 of a body of water 110. An energy source 120, perhaps seismic or electromagnetic, is actuated in the body of water, and energy is detected. A position of a survey spread 155, the spread maybe comprising a plurality of spaced-apart streamers 135 comprising geophysical sensors 125, is manipulated in response to a change in distribution of the target (e.g. depth below the bottom; depth, lateral position or width of a portion relative to another portion). A data processing system (500, Fig. 5) receives measurements of detected energy and determines the manipulation, maybe while detecting the energy or prior to data acquisition. The manipulation may comprise changes to a position of the energy source; changes to lateral position or spacing, depth, or fanning of at least one streamer; or relative positioning of two or more survey vessels 105.
Patent GB-2548592-A (GB)
Title: Transmitter outage reporting
Inventor: DALIA ABOUELMAATI
IPC: H04W88/08
Filed: 2016-03-22
Abstract: If a cellular base station detects that it is about to shut down, either because no mobile terminals are within range (64), or because of a loss of power (66), for example because a user has deliberately switched it off, it first broadcasts a report that it is about to shut down (65, 67). This broadcast signal is picked up by the neighbouring cells (44,46) and used to update their neighbour lists, thus avoiding a false alarm which would otherwise be generated by the neighbours and transmitted to a centralized Operation Administration and Maintenance system when the shut-down cell fails to be detected on the next sampling cycle. The neighbours can then retain the shut-down base station in the neighbour list. The cause of the shut-down may be identified in the shut- down report (65, 67), and a self-organising frequency reuse plan adjusted if the base station is shut down altogether (68) (for example because of a loss of power) but remain unchanged if the base station is continuing to operate in receive-only mode (60) because no mobile terminals are within its range. The base station has a standby battery which allows a "graceful" shutdown even if the main power supply is cut off.

Title: Measurement of the electric current profile of particle clusters in gases and in a vacuum
Inventor: UWE RENNER
IPC: H01J49/06
Filed: 2016-04-14
Abstract: The invention relates to the measurement of current profiles of ion or electron clusters. The faraday detector electrode consists of a large number of structural elements 15, 16 in a bipolar arrangement, where neighboring structural elements have opposite polarities and structural elements with the same polarity are electrically connected. A voltage is applied between neighboring structural elements so that before ions or electrons impinge on the detection electrode, they are deflected onto the structural elements with one of the two polarities. The current profiles on the structural elements of the two polarities are measured separately and subtracted from each other providing a current profile which corresponds to the pure ion or electron current profile. This overcomes the issue of image/mirror current generated in the detector by the approaching charged particles.

Utilizing machine learning, deep neural networks, and other computer vision techniques, attributes of images, such as color 212, composition 214, font, style 216, and texture 218 can be extracted .from a given image. A user can then select a specific attribute from a sample image 210 the user is searching for and the search can be refined to focus on that specific attribute from the sample image. In some embodiments, a negative attribute may be selected for one or more images that indicates an attribute the user does not want the result images to include. In some embodiments, the search includes specific attributes from more than one image.

Title: Radar systems and methods
Inventor: EUAN THOMAS
IPC: G01S13/78
Filed: 2016-11-09
Abstract: An electronically-scanned SSR (secondary surveillance radar) interrogator may comprise amplifier line-ups, and may be capable of Mode S All-Calls with a simultaneous ISLS (interrogation side lobe suppression) pulse in which a control beam (transmitted as a difference pattern) is added to a main beam (transmitted as a sum beam) in each amplifier line-up. One aspect of the invention introduces a 90º phase offset between the main and control beams, thereby enabling the full power capability of the TRU (transmit receive unit) to be effectively utilized, and the effective beamwidth in Mode S to be sharply defined. The system allows the transmission of the simultaneous ISLS pulse of a Mode S all-call interrogation to be transmitted using the same array as is used by the main beam. The interrogator may comprise class AB amplifiers, improving power efficiency and thermal management. The interrogator may be used within a radar system, and/or an air traffic control (ATC) system.

Title: Method and apparatus for imaging
Inventor: Richard Bayford
IPC: A61B5/06
Filed: 2017-06-19
Abstract: Electromagnetic radiation such as in the high-frequency or UHF band, e.g. 2.599 GHz at 5W radiant flux, is directed 106 towards a body part, e.g. human breast 104, to stimulate nanoparticles e.g. which have attached to a cancer biomarker and produce a temperature differential in the part, e.g. between 0.1ºC and 70ºC higher than surrounding tissue. Electrical impedance tomography (EIT) is then used to image the part of the body to identify regions having a greater temperature. The production of heat by the stimulation will disrupt the ion flow in tissue where there are nanoparticles, resulting in an impedance change detectable by EIT 38, e.g. a-EIT or td-EIT. The nanoparticles may be conductive and/or metallic and may comprise gold or iron atoms. A pharmacologically active substance may be attached to the nanoparticles. The invention may be used for example in cancer imaging and treatment, drug discovery (e.g. vectorization) or neuron imaging.
