Title: Local position indicator for subsea isolation valve having no external position indication
Inventor: WADE A MILLER
IPC: F16K37/00
Filed: 2017-02-15
Abstract: A local position indicating device for a subsea isolation valve that has no other visual signals of its position integrates to the hydraulic actuation system for the isolation valve. Three way valves, connected to an operating control line and a force closed balance line leading to opposed ends of an operating piston, are located by the isolation valve and redirected by a diver or ROV, to locally operate the valve. The balance line has a piston that is displaced with fluid pushed by the operating piston when the isolation valve is opened with hydraulic pressure in the operating control line local connection. The piston connected to the balance line moves an indicator out of its housing for the local indication that the isolation valve is open. Displaced fluid from movement of the piston in the position indicator moves a floating piston to keep seawater away from the indicating piston.

Title: Smart reordering in recursive block partitioning for advanced intra prediction in video coding
Inventor: YAOWU XU
IPC: H04N19/593
Filed: 2016-12-22
Abstract: The application relates to encoding a frame via both inter-prediction and intra-prediction. The application involves first encoding a first group of blocks which are to be inter predicted 610. This is followed by encoding sub-blocks of a second group of blocks which are to be inter predicted 614, before using the decoding pixel values of the inter predicted blocks or sub blocks to encode the intra prediction sub-blocks of the second group of blocks 618. The availability of data from the inter-predicted blocks can improve the performance of intra-prediction over processing the blocks in the scan order since more pixel data is available for intra-prediction. Preferably there is a third group of blocks which is encoded using intra prediction and the decoding pixel values of the inter-predicted blocks or sub blocks 620. Preferably the blocks of the frame are processed in raster scan order. Preferably the first group of blocks is encoded before the second group of blocks, and the second group of blocks is encoded before the third group of blocks.

Title: An active imaging system
Inventor: JOHN BARR
IPC: H04N13/10
Filed: 2021-02-02
Abstract: The system comprises first and second laser illuminators 132, 133 to illuminate a scene, including a target. The pulses of light emitted from the first laser illuminator 150 having a relatively broad spectral linewidth and a relatively long pulse duration compared with pulses of light from the second laser illuminator 160. A camera system 137 uses a relatively long gate period for receiving returns from the first laser illuminator to obtain a first image of the scene and to use a relatively short gate period together with ranging information of the target to receive returns from the second laser illuminator to obtain a second image of the target that selectively excludes non-target elements within the scene. Through image processing 121, the second image is used as a template to selectively remove the non-target elements from the first image. In this way the final image benefits from the high image quality possible from the returns of the first illuminator and the good clutter rejection from the returns of the second laser illuminator.

Title: Circuit
Inventor: Juan Mario Michan
IPC: H05H1/24
Filed: 2021-07-16
Abstract: Dielectric barrier discharge (DBD) device 10 drive circuit 20, comprising an inductance 42. The inductor and DBD’s dielectric discharge gap, which provides a capacitance 12, form a resonant LC (tank) circuit. Power is supplied to the tank in a pulse train whose frequency is tuneable to the tank’s resonant frequency. The pulse train gradually charges the tank thus reducing power loss and component stress. Discharge ignition events of the DBD are limited to a maximum number. A phase meter may detect power supply phase shifts indicating a discharge event. A drive circuit may use phase shifts to determine when the maximum number of discharge events is reached. Power may be supplied to the tank via an inverter 30 and transformer 50. The secondary windings 54 and leakage inductance of the transformer 56 may contribute to the tank’s inductance. The transformer’s primary winding 52 may be shorted by the inverter to inhibit ringing. The tank may be discharged by phase shifting the pulse train 180-degrees and discharged energy directed to a power storage device 24. A system may comprise a plurality of DBD devices and drive circuits.
