Title: A mass-selective ion trap with a toroidal ion trapping region
Inventor: GILES KEVIN
IPC: H01J49/42
Filed: 2012-08-22
Abstract: Mass selective ion traps are disclosed having increased space charge capacities. In one embodiment, the ion trap comprises a toroidal ion trapping region, ions being trapped in a first (y) direction by a pseudopotential well and in a radial direction (r) by a quadratic DC potential well. Ions are excited in said radial direction (r) so as to mass selectively eject ions in said same direction. In other embodiments (see Figures 3A-4C), an expanded three dimensional array of electrodes is arranged in two horizontal layers. A RF voltage acts to confine ions in a first (y) direction within a non-quadrupolar pseudopotential well, while a DC voltage and/or an RF voltage acts to confine ions in a second (x) direction within the ion trap. Ions are excited in a third z-direction within a quadratic potential well so as to be mass-selectively ejected in said third (z) direction.

Title: Methods, devices and computer programs for tracking targets using independent tracking modules associated with cameras
Inventor: JOHANN CITERIN
IPC: G06T7/292
Filed: 2015-12-18
Abstract: A target trajectory is determined from two image streams obtained from two sources, a sub-image of each image of the streams representing an overlapping area of a real scene. After obtaining a target path for each of a plurality of targets, each target path being obtained from a target tracker associated with a source of image, each of the obtained target paths is split into a plurality of tracklets 310-1, 310-2, 315-1 and 315-2 as a function of each potential target switch along the obtained target path. Then, the trajectory is generated as a function of a plurality of the tracklets. Preferably the tracklets are grouped into sets, where each individual target path portion of a set being obtained from a different target tracker. Preferably the step of splitting each of the obtained target paths is based on an iterative process. Preferably the iteration process comprises a step of determining whether the target location belongs to a current tracklet or is to be considered as a first location of a new tracklet. Preferably a penalty is applied when considering creating a new tracklet. The application seeks to solve the problem of keeping track of targets when their paths intersect.
