Title: Sea floor boost pump and gas lift system and method for producing a subsea well
Inventor: LANCE PORTMAN
IPC: E21B43/36
Filed: 2015-08-13
Abstract: A method and system for producing a subsea well includes installing a pump and a gas/liquid separator on a sea floor. The system flows well fluid up the well to the pump, boosting the pressure of the well fluid. The system flows the well fluid from the pump into the gas/liquid separator and separates gas from the well fluid. The stream of liquid flows up a flow line to a remote production facility. The stream of gas is injected back into the well at a selected depth to mix with the well fluid flowing up the well. The injection of gas creates a gas lift system that lightens the hydrostatic pressure of the well fluid in the well.

Title: Systems, methods, and devices for syncronization of vehicle data with recorded audio
Inventor: Jon thomas mullen
IPC: G11B27/10
Filed: 2017-04-28
Abstract: A method for post-processing to synchronize audio data 204 with vehicle data 202 includes generating an artificial or proxy sound data 208 based on time-series vehicle data. The method includes determining an offset that maximizes cross-correlation 210 between the artificial sound data and recorded audio data. The method also includes shifting one or more of the time-series data and the recorded audio data relative to each other in time based on the offset. The shift may be used to generate or render a synchronized set of time-series data and recorded audio data. The proxy sound data may modify an amplitude of a looping generic sound that replicates engine noise, internal cabin noise, external wind noise or tire noise. The proxy sound data may be based on engine speed or the vehicle speed. Video data may be rendered corresponding to the audio data.

Title: Method and apparatus for enabling a single sign-on enabled application to enforce an application lock
Inventor: ADAM C LEWIS
IPC: H04L29/06
Filed: 2015-12-04
Abstract: A single sign-on server associated with a single sign-on client authenticates a user of a device. Subsequent to the authenticating, the single sign-on client receives a request for an authentication token from a single sign-on enabled application operating on the device. The single sign-on client determines whether an application lock flag for the single sign-on enabled application is set. Responsive to the determining, the single sign-on client provides the authentication token to the single sign-on enabled application when the application lock flag is not set and withholds the authentication token from the single sign-on enabled application when the application lock flag is set.

Title: Guided tape applicator
Inventor: JOE AUGUSTINE S T LAM
IPC: B65H35/07
Filed: 2016-02-09
Abstract: A tape applicator system that employs an extendable arm to carry and control the movement of a tape applicator mounted at its moveable or free end. The tape is dispensed from a essentially fixed location remote from the applicator which permits the use of larger roll (Machine rolls) without the necessitating moving the roll as is required in a normal hand operated device. The movement of the tape applicator mounted on the arm is restricted to straight line movement by the linkage of the extendable arm. If desired a parallel linkage mechanism may be used in the arm to maintain the angular orientation of the applicator which is particularly important when the tape applicator is a common tape head normally use in taping machines. Using a constant height system the height of the tape applicator can be maintained constant when in operation.

Title: System and method for providing adaptive synchronization of LTE communication systems
Inventor: AMR EL-KEYI
IPC: H04W56/00
Filed: 2017-08-17
Abstract: The following relates to adaptive synchronization for communication systems and more particularly to adaptive synchronization of long-term evolution (LTE) communication systems. It is known that OFDM-based systems (such as LTE) are sensitive to timing and frequency synchronisation errors. This can be exploited for jamming attacks to cause denial of services for devices joining an LTE network. To mitigate this a signal receiver is provided with multiple parallel adaptive filters to eliminate the contribution of an interference signal to a timing metric of an LTE signal. Coefficients of each of the parallel adaptive filters are determined using a Linearly Constrained Minimum Variance (LCMV) criterion to minimize output power of each filter subject to the LCMV criterion that preserves received signal vectors corresponding to all possible Primary Synchronization Signal (PSS) signatures. The LCMV criterion are updated iteratively using a Recursive Least Squares (RLS) algorithm. A blocking matrix may be used to preserve the possible primary synchronization signal signatures.

Abstract: A hot wire sensor 10, fig. 3, comprises a hot wire module 14, wherein a measuring hot wire 26 and a compensation hot wire 28 can be detachably connected to a circuit of the hot wire sensor. A first contact pair 52, 54 is associated with the measuring wire 26 and a second contact pair 56, 58 is associated with the compensation wire 28. The contacts of the second contact pair are configured as leading contacts in relation to at least one of the contacts of the first contact pair, such that the contacts of the compensation wire are contacted electrically chronologically before at least one of the contacts of the measuring wire during connection. This may be achieved by different length contact pins 52, 54, 56, 58. This ensures no flow of current through the measuring wire before the compensation wire is electrically contacted and prevents undesired premature energisation. Anaesthesia apparatus and a ventilator comprising the hot wire sensor and hot wire module are also claimed.

Filed: 2018-11-13
Abstract: An alkali metal vapour chamber (cell) has an internal surface 202 comprising nanostructures 204. The cell has a window to enable the internal surface to be illuminated. An alkali metal vapour 209 may adsorb 208 onto the internal surface 202. Illumination 208 of the internal surface via the window optically excites the nanostructures 204 (light induced atomic desorption, LIAD). This raises their temperature, which induces desorption of adsorbed alkali metal atoms 208. This increases the density of the alkali metal vapour 209 in the cell. The nanostructures 204 may be quantum dots or other nanoparticles. The cell may be used in atomic clocks, magnetometers, etc.
