Abstract: FIGS. 1-16D & 66A-92D disclose a large variety of methods of forming the headgear for use in combination with a breathing apparatus including a unitary plastic core within textile casings. In some configurations, the plastic core material penetrates or bursts-through the textile casing of the straps. Some configurations include over moulding, alignment posts, T-joints and joint housings with injection aperture. FIGS. 17-65 & 93A-94C disclose a large variety of different headgear arrangements including top strap, front strap, rear strap and pairs of straps extending from the mask above and below the ear to meet behind the ear. FIGS. 95-121B disclose a large variety of connectors connecting the headgear assembly to the mask assembly where the headgear, mask and connector form a closed loop the connector is disengaged with the mask assembly.

Abstract: A respiratory mask system is provided. The respiratory mask system has a patient interface that is secured to a user's head by a headgear. The patient interface includes a seal, a frame and a gas delivery conduit. The frame is configured to secure the seal and gas delivery conduit together. The frame includes a recessed channel and/or headgear retaining features configured to connect the headgear to the patient interface. The frame can include an inlet collar that connects to a gas delivery conduit. The inlet collar can include bias flow holes. The headgear includes a top strap, a pair of side arms, a yoke and a rear strap. The yoke is configured to connect to the recessed channel of the frame. The top strap, side arms and yoke form an integrally formed closed loop. The top strap can include two portions adjustably connected to each other.

The first porous electrode, the eggshell membrane, and the second porous electrode are stacked on each other in that order. The present application also relates to an electrical energy generating device, a method for generating electrical energy, and a decorative ring.

Abstract: A decorative ring includes a body having a hollow tubular structure and defining a body space. A plurality of electrical energy generating elements is located in the body space and spaced apart from each other. The body space is divided into a plurality of sub-body spaces separated from each other. Each of plurality of electrical energy generating elements includes a first porous electrode, an eggshell membrane, and a second porous electrode stacked on each other in that order. A light emitting element is located on the body and electrically connected to one of the plurality of electrical energy generating elements. A liquid having positive ions and negative ions in the body space.

Abstract: An electrical energy generating device includes an electrical energy generating element, a first container, a second container, and a liquid having positive and negative ions. The electrical energy generating element includes a first porous electrode, an eggshell membrane, and a second porous electrode stacked on each other in that order. The first container is located on a side of the first porous electrode away from the eggshell membrane. The second container is located on a side of the second porous electrode away from the eggshell membrane. The liquid is located in at least one of the first container and the second container, and the liquid is configured to penetrate from one of the first container and the second container to another through the electrical energy generating element.

Abstract: A method for generating electrical energy includes providing an electrical energy generating element. The electrical energy generating element includes a first porous electrode, an eggshell membrane, and a second porous electrode stacked on each other in that order. The electrical energy generating element has a first side and a second side opposite to the first side. A liquid having positive ions and negative ions is allowed to penetrate the electrical energy generating element from the first side to the second side.

Abstract: An epigenome editing system generally includes three exogenous coding regions. The first exogenous coding region encodes a first polypeptide that includes an epigenetic editing domain and a domain that, in the presence of an inducer, forms a complex with a second polypeptide. The second exogenous coding region encodes the second polypeptide, which includes a dCas9 domain and a domain that, in the presence of the inducer, forms a complex with the first polypeptide. The third exogenous coding region encodes an sgRNA sequence that targets the dCas9 domain to a genomic locus.

Abstract: Disclosed is an apparatus for measuring turbidity, which includes a body case and includes a light source device, a light path absorption cell, a light path reception and detection module, a screen and a central processing unit, all of which are disposed on the body case. Spectrum of the light ray emitted by the light source device mainly has wavelengths in a range of 350 nm to 1000 nm. The spectrum has two peak wavelengths, one of which is in a range of 400 nm to 500 nm and has a half-peak width in a range of 5 nm to 50 nm, and the other of which is in a range of 550 nm to 750 nm and has a half-peak width in a range of 50 nm to 150 nm. Also disclosed is a method for rapidly measuring turbidity. By means of the present invention, turbidity of water sample can be measured accurately, simply, steadily and in high sensitivity.
