  • Publication number: 20220001556
    Abstract: Sensor-based shaving systems and methods of analyzing a user's shave event are described for determining a unique threshold value of the user. A grooming device comprises a handle having a connecting structure connected to a hair cutting implement. A shave event sensor associated with the grooming device measures a user behavior, which includes collecting a first dataset comprising shave data defining a shave event. The first dataset is transmitted via a communication device and is analyzed to determine baseline behavior data of the user, and a unique threshold value of the user is determined from the baseline behavior data. One or more subsequent datasets, each comprising shave data of one or more corresponding shave events, is compared to the unique threshold value to determine comparison data. An indication is provided, based on the comparison data, to indicate a deviation from the threshold value and to influence the user behavior.

  • Patent number: 9068065
    Abstract: The invention at hand provides hydrolytically degradable ionic copolymers. These ionic copolymerizates are composed of one cyclic ketene acetal A, one anionic or cationic methacrylic acid derivative B, selected from 2-methyl-methacrylate, [2-(2-methyl-1-methylene-allyloxy)]ethanesulfonate, [2-(2-methyl-1-methylene-allyloxy)ethyl]phosphonate or a quaternary amine of the N,N-dimethylaminoethylmethacrylic acid (DMAEMA) and, optionally, a neutral methacrylic acid derivative C. The hydrolytically degradable anionic copolymers according to the present invention are produced by polymerizing the components A, B and C in the presence of a radical initiator under inert gas atmosphere and subsequent purification. All copolymers according to the present invention are hydrolytically degradable. Copolymers comprising a maximum of 40 mol-% of ester groups in the backbone are additionally biodegradable, wherein in the case of cationic copolymers a maximum of 20 mol-% of quaternized DMAEMA is allowed to be available.

  • Publication number: 20120148493
    Abstract: The invention relates to composite materials comprising polymer nanofibers and polymer nanoparticles, wherein at least one of the two polymer materials is loaded with a substance selected from therapeutic and diagnostic agents. Fibers and nanoparticles can comprise identical or different polymers; the polymer materials are, however, biocompatible in every case. Therapeutic and diagnostic agents can be hydrophilic or lipophilic and the two polymer materials likewise. The at least one polymer material and the substance with which said material is loaded are either both hydrophilic or both lipophilic. The polymer nanoparticles of the composite materials have a diameter of 10 nm to 600 nm. The polymer fibers have diameters of 10 nm to 50 ?m and lengths of 1 ?m to several meters. The invention further relates to a method for producing said composite materials.

The system is highly stable, protects the DNA in the pulmonary environment, has a low zeta-potential and a low aggregation tendency in a medium with a high ionic strength. Furthermore, it is characterized by a low in vitro and in vivo cytotoxicity and allows for a very high transfection efficiency. The vector system according to the present invention is used for a transfection by inhalation in local pulmonary therapy.
