Abstract: A biodegradable food-grade polyvinyl alcohol (PVA) paper substrate and a method for making the same are provided. The method includes: providing a paper substrate; preparing a first coating material by rendering PVA with a degree of alkalization of 90%-100% and a molecular weight of 100,000-300,000 into an aqueous solution in which the PVA has a weight ratio of 3%-15%; preparing a second coating material by rendering sodium trimetaphosphate into an aqueous solution in which the sodium trimetaphosphate has a molar concentration of 0.05-1 Mol/l; forming a coating layer on a surface of the paper substrate; forming a surface cross-linked layer on the coating layer; and drying. The resulting PVA paper substrate is biodegradable, of food-grade quality, and resistant to water and grease, with a grease resistance higher than or equal to that corresponding to kit No. 6 in a TAPPI T559 pm-96 standard test.

Abstract: This invention relates to a cup sleeve structure with hanging ears, which comprises a cup sleeve which has an annular wall body having a top opening and bottom opening on the two sides of the annular wall body, and at least two hanging ears, which can be bent and combined to the outer surface of the annular wall. By the implementation of the present invention, the cup sleeve structure having hanging ears can completely take up the least space while being stored, and can also be conveniently carried, and can support the filter cup body in use.

Abstract: The present invention discloses a device and a method useful for the provision of secure payment and certification of digital content access, while the devise comprises: at least one IC chip containing an operating system and memory provisions, an interface of a plurality of N plated electrical input contacts (PEICs); interconnected to said IC chip; N is an integer number equal or higher than 1; and, at least one operating system able to process information and recall it, stored on said IC chip; at least one encoding mathematical formula stored on said IC chip that generates a response to input provided by entering a prescribed sequence of electrical inputs to said PEICs by means of said card reader; at least one human interface that prompts the end user to enter data and enables the entry of said data, e.g., by means of an interconnected keypad.

Abstract: The invention herein disclosed provides means and methods for monitoring the condition of infants, young children, the elderly and the incapacitated from a remote location simply and efficiently and can be regarded as a remote babysitting system.
