  • Publication number: 20240024978
    Abstract: A process for producing a 3D article by additive manufacture is provided. The method includes the steps of: forming a meltpool on an already-existing part of the article using heat supplied to the article by a gas metal arc welding device having one or more consumable electrodes, and moving the meltpool relative thereto; simultaneously feeding into the moving meltpool: (i) the one or more consumable electrodes of the gas metal arc welding device to provide a first material feed rate into the meltpool, and (ii) a non-electrode, supplementary feedstock to provide a second material feed rate into the meltpool, whereby a layer of material is deposited and fused on the already-existing part; and repeating the forming and moving, and the feeding steps to build up successive layers of material, and thereby produce the 3D article. The ratio of the first material feed rate to the second material feed rate is varied in performance of the feeding step. A related process for surface cladding an article is also provided.

  • Publication number: 20240016412
    Abstract: Monitoring apparatus for measuring the respiratory rate of a subject comprises an upper arm unit attached to a subject's upper arm in use and containing at least one movement sensor and a photoplethysmograph configured to monitor blood volume within the subject's upper arm while the upper arm unit is worn on the subject's upper arm. The output from the photoplethysmograph and movement sensor(s) are processed to calculate and output an estimate of the rate of respiration of the subject. Respiratory cycle induced variations in the photoplethysmograph signal and movement sensor signals can be independently determined and there is a greater confidence in the calculated respiratory rate when these independent calculations give consistent readings. If there is insufficient confidence, no rate of respiration is displayed.

  • Publication number: 20120144979
    Abstract: The free-space gesture MIDI controller technique described herein marries the technologies embodied in a free-space gesture controller with MIDI controller technology, allowing a user to control an infinite variety of electronic musical instruments through body gesture and pose. One embodiment of the free-space gesture MIDI controller technique described herein uses a human body gesture recognition capability of a free-space gesture control system and translates human gestures into musical actions. Rather than directly connecting a specific musical instrument to the free-space gesture controller, the technique generalizes its capability and instead outputs standard MIDI signals, thereby allowing the free-space gesture control system to control any MIDI-capable instrument.
