A toothbrush system includes a toothbrush having a floss pick with position sensors. The position sensors can be used to create a digital representation of the user's mouth and by monitoring the movement of the toothbrush while in use, the system can determine if all surface areas of the teeth have been properly brushed based upon the measured brush time and force. The system can determine if the teeth have been properly flossed based upon the measured floss time and position. If any areas of the teeth have not been properly brushed or flossed, the system can emit a signal informing the user of the areas that need additional brushing or flossing.

The invention relates to a low-density coated ceramsite proppant and a preparation method thereof, and belongs to the field of petroleum proppants. A ceramsite base material and mixed resin coating the surface of the ceramsite base material are adopted, so that compared with the traditional proppant, the breaking-resistant capacity is greatly improved, the breaking rate is much lower under the condition of the same consumption of resin, and the low-density coated ceramsite proppant can be suitable for deeper well fracturing. Compared with the traditional proppant, the production cost is lower, the chemical inertness is better, the fracturing effective period can be prolonged, and the low-density coated ceramsite proppant is suitable for the fracturing construction under various complicated stratum environment conditions and is higher in flow conductivity.

A light emitting diode device can include a pair of opposed electrodes and a thin film multilayer structure interposed between the pair of electrodes. The device can include one or more light emitting layers each having an emission interface. In the device, there can be adjacent layers having an interfacial plane therebetween. The interfacial plane being disposed in a position where an optical path length from the emission interface to the interfacial plane is substantially equal to, or less than, the coherent length of light emitted from the emission interface. Furthermore, the difference in refractive index between the adjacent layers is substantially equal to, or less than, 0.6. This can eliminate an interference effect within the thin film multilayer structure, thereby enhancing light emitting efficiency and achieving intended light color.

Provided is a light-emitting element, and a direct-view type display, capable of expanding a color-reproduction range. A plain-surface light source (1) is capable of emitting light in an area corresponding to pixels by a variable light-emitting amount. A liquid crystal cell (2b) is formed in such a manner as to correspond to each pixel on the plain-surface light source (1). On the liquid crystal cell (2b), a birefringent plate (3) is provided. On the birefringent plate (3), a quantum dot layer (4) is formed. The quantum dot layer (4) is coated in such a manner as to have a first quantum dot layer (4a) (grain size A), and a second quantum dot layer (4b) (grain size B: A<B). During a 1-field period, it is possible to form a state that ultraviolet rays are guided only to the first quantum dot layer (4a) a state that the ultraviolet rays are guided to the both dot films (4a), (4b) at an arbitrary ratio, and a state that the ultraviolet rays are guided only to the second quantum dot layer (4b). This, in a case of light in red color, allows each of pixels for respective colors to create light in red color in which different red colors are mixed, for example.

A tamper evident closure (1) includes a housing (5) containing a blister pack (2) and a substrate (3), wherein the blister pack (2) contains a first reagent which is visible prior to first opening and the substrate (3) contains a second reagent. First opening of the closure ruptures the blister pack thereby exposing the first reagent to the second reagent and effecting a reaction that causes a visual change that signals the closure has been opened. The tamper evident closure of the present invention is primarily intended to be used as an anti-counterfeit measure on a spirit or pharmaceutical bottle. In the preferred embodiment, the closure incorporates a liquid that when brought into contact with a reagent chemical contained in an absorbent pad, effects an irreversible color change. This color change will indicate to a consumer the bottle has been previously opened or tampered with. The design makes it very difficult for a counterfeiter to cover up or eradicate the visible effects. In particular, the only way a counterfeiter could do this would be to put in a replacement blister and an absorbent pad. Filling a blister pack with a liquid is a highly specialist task which makes replication very difficult. The ability to control the color change to complement the branded goods provides a way of building up consumer recognition of the product and thereby establishing confidence in those products that carry the tamper evident closure of the present invention.
