Inventor: PATRICK HO WAI SUNG
IPC: H04L12/26
Filed: 2017-09-12
Abstract: Methods and systems for transmitting data packets through a selected connection that the first data packet of a data session satisfies a match condition. The match condition is received through a user interface. When data packets of the data session are received, the data packets will then be transmitted through a selected connection. The selected connection is selected from connections based on a connection selection criteria. Further differentiated services code point (DSCP) of first data packet is changed when sent by a computing device. After a network node receives the first data packet, then resets the DSCP value before sending the first data packet.

Title: Automated luminaire identification and group assignment devices, systems and methods using dimming function
Inventor: Simon Coombes
IPC: H05B37/02
Filed: 2018-05-01
Abstract: A system and method to automatically identify, locate, and assign luminaires into groups such that lighting systems may be more efficiently configured, used, and maintained especially in large buildings etc., in which a gateway 102 is configured to control a dimming level of at least a first luminaire 112, a first sensor subsystem 108 is configured to measure a direction of and a change in the illumination received by the sensor subsystem and a server 106 is in data communication with the gateway. The gateway is configured to dim the first luminaire and then gradually reduce the dimming level. The sensor subsystem continuously measures the direction of and change in illumination as the dimming level is reduced and transmits measured data to the server, which uses the data to determine a location of the first luminaire relative to the sensor subsystem. The sensor subsystem may include a low-resolution imaging sensor, capable of detecting light patterns from individual and groups of luminaires to form virtual maps of luminaire locations which may be correlated with actual luminaire floor plans to efficiently identify, locate, and group the luminaires.

Title: Determining position of a vehicle on a rail
Inventor: Mariena Somasundaram
IPC: B61L25/02
Filed: 2018-07-26
Abstract: The position of a vehicle on a rail is determined using one or more characteristics of the rail. The characteristics of the rail adjacent to the vehicle are determined and correlated with a reference that correlates the characteristics with a plurality of positions on the rail. The characteristics may be chemical, electrical, electro-mechanical, electromagnetic, mechanical, acoustic, geometric or optical. Speed or velocity may also be determined by change in position. Determining the characteristic may comprise receiving a signal emitted or reflected off the rail. The rail may be modified at selected positions to modify the characteristic. Difference in the determined acoustic characteristic and the reference characteristic can be used to assess rail or track condition. The position for the reference characteristic may be determined from a satellite navigation system, a beacon or a map. The invention eliminates the need for active track-side equipment and provides accurate real-time estimates of vehicle position.

Title: Slotted anti-extrusion ring assembly
Inventor: GUIJUN DENG
IPC: E21B33/128
Filed: 2017-01-04
Abstract: A sealing element is flanked by wedge-shaped extrusion ring assemblies. The extrusion rings are continuous for 360 degrees and are slotted from the outside dimension and alternatively from the inside dimension to allow the diameter to increase to the surround tubular or open hole. The extrusion rings climb a ramp on an adjacent pedestal ring on the way out to the borehole wall. Depending on the dimension of the gap to be spanned the extrusion ring slides a variable distance up the pedestal ring ramp. An optional anchor ring is initially forced up an opposite ramp of the pedestal ring. If the sealing gap is short the anchor ring can be eliminated. For larger gaps the anchor ring moves out far enough toward the borehole wall to contact the extrusion ring located on an opposing ramp of the pedestal ring so that reaction forces are directed to keep the anchor ring wedged in position for support of the extrusion ring assembly.

Title: Acoustic illumination for flow-monitoring
Inventor: MAHMOUD FARHARDIROUSHAN
IPC: E21B47/14
Filed: 2013-11-01
Abstract: In methods and apparatus for monitoring a fluid flow carrying structure such as a pipe, well, or borehole 12, an acoustic wave is coupled into the structure being monitored at the same time as data logging required to undertake the monitoring is performed. By synchronising the sensing and storage of the data with the generated acoustic wave, the data collection and recording can be active only while the acoustic wave is incident on the structure, allowing the amount of data that need be collected to be reduced. An optical fibre distributed acoustic sensor (DAS) 10, 14 is used to detect the incident acoustic wave or pulse. The acoustic wave may be caused by a seismic source 90 or an acoustic source internal to the structure, such as a passive clapper or spinner (figure 10, 110), or valve.

Title: A switching device
Inventor: BERND SPRITZENDORFER
IPC: H01H71/52
Filed: 2019-07-16
Abstract: A switching device 1 comprises a contact arm 3 carrying a movable contact 4 which contacts a fixed contact 6, a switch lock 2 connected with the contact arm, a hand-switching lever 7 connected to the contact arm, and a connecting rod 10. The switch lock comprises a latch 20 and a latch support 22. The connecting rod is mounted movably on the latch support and has an end portion 12 which bears against a first projection 11 of the lever when in a stationary (final) position in which the contacts are closed. The connecting rod further comprises an actuating shoulder 29 which bears against a second projection of the lever when in a non-stationary position (non-final position) in which the contacts are still closed. When actuating the lever to separate the contacts, the contact rod is moved to release the latch. Thus, when the lever is moved to open the contacts while in the non-stationary position, the second projection passing over the shoulder activates the jump-off function so that the contacts are opened at high speed, ensuring an arc is not generated. The second projection may be arranged on the first projection.

Title: Document authentication by attitude-independent determination of surface appearance using controlled illumination
Inventor: ANDREW BUD
IPC: G07D7/20
Filed: 2020-04-08
Abstract: A user is guided to relatively move 114 a device equipped with an illuminator 106 and a camera 104, such as a smartphone 102, with respect to a document 110 whose genuineness is to be assessed. The motion may include changing the distance between the camera and the document by moving the camera or moving the document. Imagery of the document is captured by the camera during the movement and images are analysed to determine a likelihood that the document includes features indicative of genuineness, such as a hologram, an original photograph, or other regions matching those of a genuine document. The analysis may include identifying regions exhibiting large changes in appearance over relatively small distance changes and obtaining the spatial extent of document features. The user may be provided with movement instructions for the camera or document. The illuminator may be a display screen. The image analysis may determine changes in appearance of the document resulting from the illumination incident on the document and the position of the camera caused by the changing distance. Alternatively, the intensity or colour of the illumination and the spatial arrangement of the document and camera may be changed while images are captured.

Title: Colour slider
Inventor: INON BEISER
IPC: H04S7/00
Filed: 2020-06-22
Abstract: Adjusting gains of an audio mix. Audio tracks using respective gains are individually analysed to compute a first metric of frequency content. A user input specifies a desired second metric of the frequency content. Responsive to the user input, respective gains of the audio tracks are collectively and simultaneously adjusted to produce respective adjusted gains of the audio tracks. A second audio mix when played of the audio tracks with the respective adjusted gains has a third metric of frequency content different from the first metric of frequency content. The third metric is closer to the second metric than said first metric. Preferably, a previously determined frequency-dependent audio filter is applied to the audio tracks and measures respective loudness values, and the gains of the audio tracks are then adjusted in response to the loudness values. Preferably the adjusting of gains involves normalisation thereby maintaining the loudness of the audio mix.
