92 results about "Mouth roof" patented technology

[edit on Wikidata] The palate /ˈpælɪt/ is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but, in most other tetrapods, the oral and nasal cavities are not truly separate.

Devices, systems, and methods using magnetic force systems in or on soft palate tissue

An implant system places magnetic structures in or on tissue that develop a magnetic repelling force between a soft palate a posterior pharyngeal wall. The magnetic repelling force has a magnitude F-mag, where F-mag=f (F-sep, F-nat), and where F-sep is a force required to separate soft palate tissue from pharyngeal wall tissue during sleep, and F-nat is a force exerted by native muscle on the soft palate during swallowing and / or drinking and / or speech. In another embodiment, a palate implant uses attractive magnetic force to keep the airway open.

Automatic cup type beverage vending machine

An automatic cup type beverage vending machine capable of mixing small pieces of ice and a liquid material finely and uniformly through the entire beverage. A liquid material (sugar and cream diluted with diluent hot water and a coffee solution) and small pieces of ice are agitated by an agitation mechanism and the cup is shaken by a shaking mechanism. Mixing of the liquid material and small pieces of ice can be performed not only by agitation of the liquid material and small pieces of ice but also by shaking of the cup. Therefore, the liquid material and small pieces of ice can be mixed uniformly and finely with each other in the entire beverage and any parts of them are not left in an insufficiently mixed state. The machine can therefore prepare a beverage which is not inferior in terms of touch to the tongue and palate and appearance to one prepared by mixing a liquid material and crushed ice while crushing ice by a mixer as in a beverage store.

Modified tooth positioning appliances and methods and systems for their manufacture

The present invention provides improved devices, systems and methods for producing dental molds, each having portions representing a patient's oral soft tissue and a desired tooth configuration. These molds are designed for use in the fabrication of appliances used in orthodontic treatment, particularly, elastic repositioning appliances. However, they may also be used in the fabrication of traditional appliances, such as retainers and positioners, used, for example in the final or finishing stages of an otherwise conventional treatment. The dental molds are comprised of a mold or relief of the patient's soft tissue, such as a palate, facial gingival tissue and / or lingual gingival tissue, and a separate or separable mold or relief of the patient's dental arch having teeth in a desired tooth configuration. Since, the tooth configuration will change as a patient progresses through orthodontic treatment, the relief of the dental arch will be fabricated separately from the relief of the oral soft tissue. Typically, the dental arch relief will be fabricated using rapid prototyping methods. The soft tissue relief may also be fabricated using rapid prototyping, however it may also be fabricated using traditional mold making methods, i.e., casting with plaster or other mold making materials. In either case, the resulting dental mold with be comprised of a “split-mold” having fixedly or removably joined arch and soft tissue reliefs.

Intra-oral tissue conduction microphone

Intra-oral tissue conduction microphone apparatus and methods are described for internal, but non-surgically installed microphones located in the oral cavity. An intra-oral tissue conduction microphone may be attached, adhered or integrated with a removable dental appliance which is positioned against the inside surfaces of the cheek, palate or gingiva. The sensor serves as a component in a non-observable hearing, body sound monitoring or communications device that can operate in environments incompatible with most existing devices. Generally, a piezoelectric film serves as the sensor that is well matched to tissue and which directly converts to an electrical signal by the piezoelectric effect signals which are received through the oral mucosa, gingiva or palate.

Method for welding railway vehicle side wallboard

The invention discloses a method for welding side wall plates of a train lorry, including the steps: (a) the side wall plates are stretched along the direction of the welding edges of the side wall plates so as to cause the side wall plates to be elastically deformed; and (b) a plurality of elastically deformed side wall plates in the step (a) are respectively paired to be welded, and the drawing force causing the side wall plates to be elastically deformed is maintained during welding. The method has the technical scheme that before the side wall palates are welded, certain. stretching stress is applied to both ends of each side wall plate along the direction of one welding edge so as to elastically deform each side wall plate to a certain degree. When the side wall plates are elastically deformed, pull stress is generated in each side wall plate; in the process of welding, crystal grains are heated to be expanded and are mutually extruded; and the existence of the pull stress counteracts the thermal expansion pressure stress among the crystal grains, thus the plastic deformation of the crystal grains can be eliminated or lessened, thereby preventing a welding seam from being retracted, and effectively reducing the planeness of the side wall plate.
