Title: System and method for regulating RMS voltage delivered to a load
Inventor: VALENTI LEO F
IPC: G05F1/45
Filed: 2011-04-19
Abstract: A system and method for regulating the root mean square (RMS) voltage delivered to a load by an alternating current (AC) electrical circuit having a line voltage. To avoid radio frequency interference (RFI), the load is disconnected from the AC electrical circuit when energy stored in the load is at or near zero and is reconnected when the line voltage is at or near zero. Inductive loads are disconnected when the line current is at or near zero while capacitive loads are disconnected when the line voltage is at or near zero. The duration of the disconnection does not exceed one half-cycle of the fundamental frequency. Disconnections alternate between removing positive voltage half-cycles and negative voltage half-cycles to avoid a direct current (DC) bias. A system incorporating digital logic elements is provided for implementing the method and for detecting whether the load is inductive or capacitive.

Title: Ultrasonic detection of a change in a surface of a wall
Inventor: CEGLA FREDERIC BERT
IPC: G01B17/02
Filed: 2013-04-08
Abstract: A change in a surface of a wall is detected by transmitting a pulse of input ultrasonic vibrations into a proximal surface of the wall and then receiving ultrasonic vibrations from that proximal surface. The received ultrasonic vibrations are compared with a previously detected pulse of output ultrasonic vibrations that have been received from the proximal surface in order to identify, for example, a time of arrival of a current pulse of output ultrasonic vibrations. The time of arrival of this current pulse of output of ultrasonic vibrations may be used to detect a change in the surface of the wall, such as a change in the thickness of the wall. Other embodiments can detect a change in the roughness profile of the wall using changes in the received ultrasonic vibrations other than arrival time. Figure 6 illustrates how the received ultrasonic vibrations from the detected pulse reflected from the distal surface wall may be compared with a previously detected pulse of output ultrasonic vibrations using a technique such as cross-correlation to determine the arrival time of the current pulse of output ultrasonic vibrations in the received ultrasonic vibrations.

Title: Digitally generated communication on power based on separately modulated power and data signals
Inventor: PUCHIANU SILVIU
IPC: H04B3/54
Filed: 2013-08-29
Abstract: A method of data communication on a power line in a deep sea hydrocarbon well facility where above sea a power signal half H-bridge A and a data signal half H-bridge B comprising respective DC supplies 12, 13 output respectively a power signal and data signal for combination and transmission over an umbilical line 20. Switches 15, 16, 18, 19 are independently operated by digital signal processors 14, 17 to generate AC waveforms from the DC supplies 12, 13 to form power and data signals using pulse width modulation. The low frequency power signal and high frequency data signal are combined and the voltage difference between them forms a communication signal that is transmitted to a subsea facility where data is extracted by discriminator 21 and power is provided to load 25. A data half H-bridge C at subsea level may transmit data topside using the same method. The system overcomes the problem of losses and data distortion inherent in systems using filters. Field programmable gate arrays or microcontrollers may alternatively be used as the modulation means.

Filed: 2013-10-10
Abstract: A method for loading data into a target system, the data comprises entities having a corresponding unique primary data value and one or more corresponding secondary data values. At least a portion of the secondary data values has associated foreign key relationships. Each foreign key relationship links the corresponding secondary data value to the corresponding primary data value of another entity. The method comprises the following steps: splitting the entities into insertion leaf groups by execution of an iteration process comprising execution of consecutive iterations, wherein execution of each iteration involves generation of a respective set the insertion leaf groups, the respective set of the insertion leaf groups containing all entities whose secondary data values have either no foreign key relationships or only one or more foreign key relationships with the primary data values of the entities of the insertion leaf groups generated during execution of any prior iteration, wherein the iteration process is executed until there are no entities left whose secondary data values have either no foreign key relationships or only one or more foreign key relationships with the primary data values of the one or more entities of the insertion leaf groups generated during execution of any previous iteration, wherein a sequence of generation of the sets of the insertion leaf groups is recorded; and consecutively loading the sets of the insertion leaf groups of the entities and the foreign key relationships linking their secondary data values with the corresponding primary data values into the target system according to the sequence.

Title: Lever actuated compression latch
Inventor: BENNETT NICHOLAS PAUL
IPC: F24C15/02
Filed: 2013-02-06
Abstract: A lever operated compression latch has an elongated, hook-ended pawl carrying a longitudinal slot, and is cam guided and pin rotated while translated to engage and withdraw from a keeper cup. The compound movement of the pawl includes a lateral translation towards the keeper cup while rotating there into, followed by a lateral withdrawal to exert a compression force between the latch body which is attached to a door and the keeper cup which is attached to a door frame. A series of interconnected links is operated by a lever handle to fold into one another to provide a compact envelope when the latch is closed and to expand outwardly to open the latch and disengage the pawl from the keeper when operated by the lever. Of this series of links, a pair of release links operates in contact with one another, and rotates on respective individual pivot points to extend outwardly from the latch envelope to engage a striker plate portion of the keeper cup. This striker engagement causes the release links to push the latch and the door from a sealing engagement with the keeper and door jamb for a short distance, prior to the latch and the door thereafter being fully opened. This striker engagement of the release links also causes the latch links to fold inwardly which rotates and translates the pawl into keeper engagement and compression. This operation is facilitated with a floating spring having one end operating as a pivot member. A detent engages one of the links to provide a physical indication to the handle lever between the hard closed position and the closed about to open position.

Title: Circuits for generating sweep frequency signal
Inventor: ZHAO ZIRAN
IPC: H04B1/7136
Filed: 2014-05-08
Abstract: The circuit comprises a reference frequency source 110 coupled to two (or more, fig.3) signal sources 121 & 122. The signal sources, described as frequency combination circuits, may use phase locked loops (PLLs). The first signal source 121 is operable to generate a sweep frequency in a first frequency band. The second signal source 122 is operable to generate a sweep frequency in a second frequency band different from the first band. A selector switch 130 is operable to select the output of signal source 121 or 122. A controller 140 may operate the signal sources 121 & 122 and the switch 130 to provide e.g. a first frequency in a first band, then a first frequency in a second band, then a second frequency in the first band. The sweeping speed is enhanced, and the hopping frequency width is extended while the sweep frequency signal has a highly pure spectrum with a low noise level. The switch 130 may contain multiple stages of cascaded switches to provide low feed-though at the operating frequency. The circuit may find application at microwave and millimetre wave frequencies; the description refers to imaging systems.
