Title: Fire damper
Inventor: Mike Backham
IPC: F24F13/10
Filed: 2019-04-05
Abstract: A fire damper for closing ventilation ducting in the event of fire has two or more sets, e.g. concentrically, of partial openings such as pilot holes, bores, centre-punch dimples or punch-outs to assist in connecting the fire damper to different types of supporting structure. The damper comprises a central flow opening and an outer flange 16 for mounting to the support structure; the outer flange having at least two sets of the partial openings 50, 52. Dampers installed in ducting where it passes through walls require fixing to the wall and fastener size spacing requirements vary depending on the wall type e.g. drywall (smaller fastener, closer to the opening) or masonry (larger fastener, further away). The where the pilots are holes they are of smaller diameter or partial depth or combinations thereof to avoid unused pilots compromising fire performance of the damper and to maintain visual appearance. The installer drills-out or punches-out to provide a fastener bore. The pilots may also be used to guide the pitch of ad-hoc mounting holes should on-site modification be required.

Title: Method and apparatus for simultaneous multi-user and direct link transmissions with reduced interferences
Inventor: MICKAËL LORGEOUX
IPC: H04W88/04
Filed: 2020-12-04
Abstract: A triggering frame in a wireless network. grants a medium to an access point AP for a transmission opportunity TXOP. The frame defines resource units RUs and allocates Uplink RUs to UL transmissions for an UL duration and Direct Link DiL RUs to P2P transmissions. All the P2P exchanges are nested within the UL duration, hence avoiding an acknowledgment frame in the DiL RUs to interfere with a block-ack frame of the AP after the UL transmissions. This is relevant for DiL RUs adjacent, in frequency, to the other defined RUs. The block ack frame is duplicated over the DiL RUs The RU immediately adjacent to the DiL RUs is declared, in the triggering frame, as being unused and no non-AP station is allowed to use it during the UL duration, or even the TXOP. Such empty RUs may be declared only in case the DiL transmission requires a response frame from the destination P2P station.

Title: Method and system for detecting peaks in a heartrate signal
Inventor: DAVID ROBERTAUD
IPC: A61B5/352
Filed: 2021-01-07
Abstract: Obtain a series of heartrate values which represent a heartrate signal. Determine an upper percentile value (Upv) and a lower percentile value (Lpv) from the series of heartrate values. Identify segments 400 from the series of heartrate values where in each segment the heartrate signal first exceeds the upper percentile value and then goes below the lower percentile value, e.g. using a hysteresis comparator. A heartrate value within each segment is selected as a peak for the heartrate signal. For example, the first value in a segment is selected as a peak. The upper percentile value may be between the 80th and 99th percentile. The lower percentile value may be between the 70th and 50th percentile. An inter-beat interval (IBI) may be calculated from the peak values. The upper and lower percentile values may act as dynamically changing, adaptive thresholds because they depend on the heartrate values.

Title: System for determining the cleanliness of mass spectrometer ion optics
Inventor: DAVID GORDON
IPC: H01J49/06
Filed: 2021-08-26
Abstract: A mass spectrometer is disclosed comprising ion optics for guiding ions to an ion detector. The spectrometer is repeatedly switched between a first mode of operation in which the ion optics are unable to transmit ions having a first mass to charge ratio or first polarity to the ion detector, and a second mode in which the ion optics are able to transmit said ions to the detector for a time period (the dwell time). The intensity of an ion signal 12 detected at first and second times 16 & 20 in each of the time periods that the ion optics are in the second mode is determined, and how said intensities vary with time is monitored. An output indicating that the ion optics are dirty is then produced if the intensities obtained at said first time 16 vary with time in a different manner to the intensities obtained at said second time 20.

Abstract: A building ventilation system for extracting stale air from within the building 1 and introduces fresh ambient air from outside the building. The ventilation system is operable to remove a predetermined amount of moisture from the building environment, and takes account of the difference in moisture content between the extracted and introduced air.
