Title: Intermediate two-dimensional scanning with a three-dimensional scanner to speed registration
Inventor: Oliver Zweigle
IPC: G01S17/48
Filed: 2014-12-09
Abstract: A method for measuring and registering 3D coordinates has a 3D scanner measure a first collection of 3D coordinates of points from a first registration position. The 3D scanner collects 2D scan sets as 3D measuring device moves from first to second registration positions. A processor determines first and second translation values and a first rotation value based on collected 2D scan sets. 3D scanner measures a second collection of 3D coordinates of points from second registration position. Processor adjusts the second collection of points relative to first collection of points based at least in part on first and second translation values and first rotation value. Processor identifies a correspondence among registration targets in first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of first and second collection of 3D coordinates.

Title: Mobile communications system
Inventor: Mark W Rayne
IPC: H04W92/02
Filed: 2017-08-24
Abstract: A method for performing end-to-end encryption in a communications system comprising two or more interworking communications systems, particularly between LTE (Long Term Evolution) and TETRA (Terrestrial Trunked Radio) communication systems. TETRA systems use frame stealing techniques to insert encryption synchronisation information in place of one or more encrypted speech frames. LTE systems generally have sufficient bandwidth that frame stealing is not required. To provide end-to-end encryption between the two systems, a communications device generates encrypted speech frames and one or more encryption synchronisation frames for transmission. The device associates each of the one or more encryption synchronisation frames with one or more corresponding encrypted speech frames of the encrypted speech frames and transmits a set of frames comprising the encrypted speech frames and the one or more associated encryption synchronisation frames. System infrastructure of the communications system receives the set of frames, replaces (or steals) one or more of the encrypted speech frames with a corresponding encryption synchronisation frame. This produces a modified set of frames which can be transmitted to one or more TETRA communications stations. Particularly applicable to the 3GPP Mission Critical Push-to-Talk (MCPTT) protocol.

Scheduling data may be used in determining RF conduction path active periods. Alternatively, an antenna tuner control modem 220 may be woken to receive a status communication signal which determines the activation of the first or second RF conduction paths. The antenna tuner 216 may have a separate power supply to that of the second transceiver 214. An efficient multiple band communication system with reduced current drain may be provided.

Title: Gas treatment process and gas treatment apparatus
Inventor: EWAN MCADAM
IPC: C10L3/10
Filed: 2019-06-12
Abstract: Hollow fibre membrane contactors in series can be used to remove carbon dioxide from input gas (e.g. biogas from an aerobic digester), using an ammonia solution, to purify the methane gas recovered. A first carbon dioxide absorption solution, comprising ammonia, absorbs some of the carbon dioxide in a first gas-liquid contact stage. In a second stage, a second carbon dioxide absorption solution, comprising ammonia, absorbs carbon dioxide from the intermediate gas. The volume of the second carbon dioxide absorption solution may be at least twice the volume of the first carbon dioxide absorption solution. The hollow fibre membrane may be PTFE or polypropylene. Recirculated ammonium bicarbonate solution can be chilled to help prevent fouling of the membrane. Lumen-side crystallisation can be precluded, and shell-side crystallisation facilitated, by suppressing ammonia volatility through absorbent refrigeration and shifting the ammonia-ammonium equilibrium.
