Abstract: A fuel cell tube 100 includes a substrate with a major surface 110a across which a plurality of, preferably solid oxide, fuel cells 130, 140, 150 extend laterally. One or more of the fuel cells 140, 150 is laterally segmented, each including fuel cell portions 140a-b, 150a-b that are electrically isolated from one another. Preferably, a segmented fuel cell is located at each end of the tubular substrate. When assembled into a stack, pairs of secondary interconnects (12a-b, 34a-b, 56a-b; figure 6) electrically connect adjacent fuel cell tubes via each separate portion of their respective laterally segmented fuel cells. Fuel cells are preferably located on opposed planar major surfaces of a flattened tubular substrate, with laterally segmented fuel cells 140, 150 on one surface being coupled to laterally segmented fuel cells (160, 170; figure 2) on the other surface.

Title: Audio processing
Inventor: TONI HENRIK MÄKINEN
IPC: H04S7/00
Filed: 2019-11-11
Abstract: An audio focusing system receives multi-channel audio signals representing a spatial audio image from a mic array (112) and an indication from a user of an audio focus direction (120) corresponding to a first beam pattern. The overlap between two beam patterns (eg. the hatched area in fig. 3) is calculated and a primary beamformed sound direction is emphasized (125) in the output audio signal compared to sounds from other directions. The beamformer may be dynamic or static based on the distance to a centre point of the image area. This process results in sharper audio focus by avoiding sidelobe and attenuation effects which would emphasize multiple objects.

Title: Improved tap assembly
Inventor: Jed Taylor
IPC: F16K21/00
Filed: 2021-07-01
Abstract: A tap assembly may have two conduits 110, 120. The first conduit 110 may be a resilient tube. When the tap is closed, component 130 may simultaneously pinch shut the first conduit and block off the second conduit 120 (shown in Fig. 1). No beverage can then flow from the tap. Moving the component 130 into a first position (Fig. 2), the first conduit 110 may be opened while keeping the second conduit 120 shut. This conduit 110 may comprise a pigtail to enable dispensing high-pressure beverage at a controlled flow rate, i.e. without excessive fobbing. Moving the component 130 into a second position (Fig. 3), both conduits 110,120 may be opened. As beverage is tapped, the pressure in the container drops to where the first conduit 110 may become ineffective at dispensing. Dispensing may proceed at lower pressures by additionally opening the second conduit 120.
