A battery assembly includes a battery that has a top surface surrounded by a circumferential edge; and a removable tab attached to the top surface. The removable tab includes a first tab end and an oppositely disposed second tab end; a gripping region disposed adjacent to the first tab end; and a battery cell attachment region disposed adjacent to the second tab end and attached to the top surface of the battery. The battery cell attachment region has first and second oppositely disposed sidewalls, wherein the second tab end is curved inwardly away from the circumferential edge of the battery such that a portion of the top surface of the battery is exposed between the second tab end and the circumferential edge of the battery

Provided is a PSA sheet that can combine bonding reliability and peeling removability, and further can be peeled off without causing deformation or damage to the adherend in various peeling modes. The PSA sheet provided by this invention has a PSA layer. The PSA sheet has a water-peel strength of 2 N/10 mm or less. The PSA sheet further has a stress at 100 % elongation of less than 30 MPa as well as a multiplication product (σf-εf) of fracture stress σf (MPa) and fracture strain εf (%) of 250 or greater.

Film stacks are described. In particular, film stacks including a base overlaminate film layer and a removeable skin layer disposed on the base overlaminate film layer are described. Because the removable skin layer develops haze before the point of irreversibly damaging the base overlaminate layer, the film stack can prevent unintentional overstretching when the film stack is stretched together.

A substrate-free adhesive tape that is excellent in adhesive physical properties and is suitable for a continuous process is provided. The substrate-free adhesive tape includes a release film, and an adhesive layer provided on one surface of the release film and the adhesive layer containing a cured product of an adhesive composition, wherein when the release film is fixed on the outer surface of a semicircular tip part of a jig, the semicircular tip part having a radius of 22.5 mm, a breaking distance of the adhesive layer is 110 mm or less when the adhesive layer is stretched at a rate of 20 m/min from a semicircular center of the semicircular tip part toward an outermost direction of the semicircular tip part.

The present invention relates to an adhesive tape comprising at least one carrier that has a thickness of 20 to 250 μm, preferably 50 to 150 μm, and has at least one layer (i) based on preferably uncrosslinked thermoplastic polyurethane that has been produced by means of extrusion, wherein the polyurethane is based on aromatic polyisocyanate, such as aromatic diisocyanate in particular, or (ii) based on preferably uncrosslinked polyurethane that has been produced from a dispersion, wherein a pressure-sensitive adhesive layer is disposed on at least one side, preferably both sides, of the carrier. The invention also relates to processes for producing the adhesive tape and to the use thereof for bonding of components in electrical, electronic, optical or precision mechanical devices, such as, in particular, of windows or lenses in housings of precision mechanical, optical and/or electronic devices.

The pressure sensitive adhesive tape is superior in moisture resistance because of its high peel strength and is easy to peel from an adherend by including a filler in the adhesive layers.

The invention relates to an adhesive strip which can be detached substantially on the adhesion plane in a residue-free and nondestructive manner by stretching, said strip consisting of one or more adhesive material layers and optionally one or more intermediate carrier layers, at least one of the adhesive materials layers containing at least one filler, the primary particles of which can be individually separated, wherein the primary particles (i) are substantially spherical and (ii) have an average diameter d(0.5) of less than 10 μm, and the ratio of the average diameter d(0.5) of the primary particles to the thickness of the adhesive material layer in which the primary particles are contained is less than 1:2. The invention also relates to the production and use of said adhesive strip.

A portable information device includes: a chassis; a decorative plate fixed to a part of an outer face of the chassis with stretch releasable double-sided adhesive tape; and a cover member that covers the outer face and the decorative plate. The double-sided adhesive tape has: an adhesive portion including adhesive layers on first and second faces of a substrate for adhesively fixing between the decorative plate and the outer face; and a tab including release paper partially covering the adhesive layers to let a user hold the tab for stretch release of the adhesive portion from between the decorative plate and the outer face. The double-sided adhesive tape has a first groove and a second groove on the first face and the second face, respectively, that are positioned not to overlap in a thickness direction of the substrate.

Brain motion monitoring systems and methods are disclosed that can detect interpret and/or display normal and abnormal brain motions. The devices and methods can detect Cerebrovascular Stenosis and provide for Noninvasive Intracranial Pressure Measurement.

A battery assembly includes a battery that has a top surface surrounded by a circumferential edge; and a removable tab attached to the top surface. The removable tab includes a first tab end and an oppositely disposed second tab end; a gripping region disposed adjacent to the first tab end; and a battery cell attachment region disposed adjacent to the second tab end and attached to the top surface of the battery. The battery cell attachment region has first and second oppositely disposed sidewalls, wherein the second tab end is curved inwardly away from the circumferential edge of the battery such that a portion of the top surface of the battery is exposed between the second tab end and the circumferential edge of the battery
