Title: Multi-rate wireless communication network
Inventor: LEI ZHANG
IPC: H04L27/26
Filed: 2016-11-30
Abstract: Transmitting and receiving data in a wireless communication network is described. Data is transmitted 305 by transforming 301 plural data symbols ak to be transmitted on a plurality of subcarrier frequencies within a frequency sub band into a time-domain multicarrier signal, upsampling 302 the time-domain multicarrier signal at a selected appropriate upsampling rate, filtering 303 the upsampled signal to remove upsampling images, and transmitting the filtered upsampled signal over a wireless communication channel. A complementary receiver (Figure 4) converts the received signal to a digital signal at a selected sampling rate, which may be selected according to signaling provided by the network, transforms the digital signal from the time-domain into a plurality of frequency-domain subcarrier signals, and performs equalization on the frequency-domain subcarrier signals to obtain an estimated data symbol. Methods of cancelling interference between sub-bands (inter-subband interference) are also disclosed. The arrangement may take as input sub-bands of data of different sampling rates (i.e. multi-rate data) and converts the data such that the signals received in the multiplexing stage 304 have the same sampling rate as each other (i.e. different upsampling rates may be selected for each sub-band).

Title: Subsea manifolds
Inventor: MORGAN CORREC
IPC: E21B43/017
Filed: 2017-07-04
Abstract: A subsea manifold layout interconnects subsea pipelines 22 that extend beside each other to convey hydrocarbon production fluids in use. Each of the pipelines has an in-line manifold portion 44 that is installed with the pipeline and lowered with the pipeline from the surface, for example using S-lay, J-lay or reel-lay techniques. Thus, the in-line manifold portions of the respective pipelines are structurally separate from each other. Bridging pipes 50 complete a subsea manifold structure comprising two or more of the in-line manifold portions, providing for production fluids to flow between the pipelines via the manifold portions of the respective pipelines. Connections to subsea wells are by jumper lines 26 and valved 32 sub-branches 30 which, together with the bridging pipes, allow production fluid from any well branch to flow to either or both pipelines. The individual manifold structures are lighter than comparable unitary dual manifolds and may be laid on separate and mudmat foundations.

The trained parameters comprise core parameters 123 received from a server 103, shared parameters 131 received from another computer in the network, and parameters 127 local to the computer in question. The trained parameters may, for example, be weights in an artificial neural network. At least two of the computing nodes may calculate different predicted outputs to the same input attributes, taking account of a user’s individual circumstances. The output of the model may identify temporally-dependent attributes of a perishable unit, e.g. tickets for a travel service, hotel rooms, restaurant reservations, or physical goods.

Title: Breathing function examining instrument
Inventor: SHINYA KUROSAWA
IPC: A61B5/08
Filed: 2016-07-12
Abstract: This breathing function examining instrument (1, 2, 3, 50, 70) measures the internal pressure of the oral cavity of a subject which varies with breathing and is provided with a main body (5, 6), a resistance setting unit (40, 60, 80) and a pressure measuring unit (32).

The main body (5, 6) is further provided at one end with a one-way valve (11) for preventing air from flowing thereinto from the outside and allowing the subject to intake air through the other end without a one-way valve. The resistance setting unit (40, 60, 80) variably sets the degree of inflow resistance to which air flowing into the main body is subjected. The pressure measuring unit (32) measures the pressure of air flowing in the tube of the main body as an oral cavity internal pressure.

Title: Measurement method
Inventor: STEPHEN BEAUMONT
IPC: H04B3/46
Filed: 2018-03-29
Abstract: A method of determining the effectiveness of an intervention (i.e. repair/change) in a metallic access network, such as an ADSL, is described. The effectiveness measure (E) is determined based on the maximum achievable data rate (MAR), attenuation (ATT) and signal to noise ratio (SNR) values, measured before and after the intervention, and is used to determine whether a further network intervention is required. The effectiveness (E) may be based on a ratio of the measured values and compared to one or more threshold values to categorise the impact/improvement of the intervention such as negative, negligible or positive to indicate whether a further intervention is required. The ratio values may be defined as the vertices of a triangle, and used to calculate the area of said triangle. The area of the triangle is the measure of effectiveness of the invention (see fig.3). The effectiveness may be determined by an Operational Support System, OSS, 200 and may be transmitted to a mobile terminal 400 used by a network engineer. Alternatively the mobile terminal may calculate the effectiveness in conjunction with ‘before’ values supplied by the OSS. The aim is to give a test engineer an indication whether a repair has been successful or further work is required.

Title: Packet data convergence protocol (PDCP) duplication deactivation
Inventor: OLIVIER MARCO
IPC: H04W88/06
Filed: 2018-04-05
Abstract: A user equipment (UE) performing Packet Data Convergence Protocol (PDCP) duplication, where the Protocol Data Units (PDUs) are transmitted to the PDCP receiver over first and second radio links, implicitly deactivates the process when specified conditions of the duplication process are met. The conditions may be associated with various quantities exceeding respective thresholds, such as the number of PDUs being buffered before transmission (not including duplicates), the transmission window size of the duplication process, the queuing time of the Service Data Units (SDUs), and the time difference between transmission of duplicate PDUs on the first and second radio links. The specified conditions may apply only to the duplicate link or to the control bearer of either the first or second radio links. The UE may revert to split bearer operation following the deactivation. The system avoids wasting radio resources in situations where PDCP duplication is not required but would otherwise remain active, and finds application with URLLC services in 5G NR networks.

A holder sensor 122 may detect a sample carrier 160 in a holder 120, perhaps for a swab or probe, which may be attachable to the device. The device may be handheld, and have a user interface 103; a user may provide input to initiate or control desorption. The device or the sample carrier may comprise the desorber and/or the controller.
