Abstract: A biaxially oriented polyethylene film structure comprises at least three layers, including a core layer, wherein the core layer comprises: i) from 50 to 99.5 weight percent of a first polyethylene which is an ethylene copolymer having a density of greater than 0.940 g/cm3; and ii) from 0.5 to 50 weight percent of a second polyethylene which is a polyethylene homopolymer composition having a density of at least 0.950 g/cm3; wherein the polyethylene homopolymer composition further comprises a nucleating agent or a mixture of nucleating agents. The biaxially oriented film has very good optical properties.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for student accountability systems. School buses can be equipped with a bus system that executes a driver application. Students carry student identification (ID) systems that identify the students to the bus system, which in turn reports a geographic location to a student accountability system. The bus system is configured to permit rapid boarding and easy usage by drivers. The student accountability system provides a parent portal and an administrator portal to monitor the students and provide other useful functions.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for vehicle inspection and passenger tracking. In one aspect, a portable vehicle data input device includes an electronic display and a data processor coupled to the display and containing instructions configured to cause the device to: display information related to inspection of different portions of a vehicle, receive driver input indicating completion of vehicle inspection tasks, display information related to a plurality of passengers associated with the vehicle, receive input identifying specific passengers as the specific passengers board or exit the vehicle, and update a roster of passengers in response to receiving the input.

Abstract: A method of decreasing the concentration of certain contaminants in liquids by the chemical reduction of the contaminant using a hydride. A suitable reactor is charged with the contaminated liquid. An amount of catalyst and then an amount of hydride are added to the reactor. The hydride reacts with the contaminant in the liquid, chemically reducing and thus destroying a portion of the contaminant and thereby reducing the concentration of the contaminant in the liquid. Additional hydride can be added to further reduce the concentration to meet a desired level.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for tracking students on school buses. In one aspect, a method includes storing, in an onboard computing device, a list of students associated with respective stops on a bus route, storing, in the onboard computing device, a list of students on the bus, determining that the bus has reached a designated stop, and presenting on a display a list of students associated with the designated stop. As each student enters or exits the bus, the methods include receiving an electronic signal identifying the student entering or exiting the bus and adding or removing the student to or from the list of students on the bus.

Abstract: A cylindrical reactor has walls and a base, forming a chamber in which permanently manufactured micelle array nanoparticles may be manufactured. The reactor has a disk impeller inside the chamber which serves to mix reagents in the chamber and a collar which facilitates the mixing process. The reactor is effective to input an amount of energy to the mixed reagents such that particle coagulation is prevented but formation of PCMA nanoparticles is permitted. A method for manufacturing PCMA nanoparticles is disclosed. Reagents, beginning with prepared core particles, are stepwise added to a reactor and mixed. A high sheer mixing unit is used to input an amount of energy to the mixed reagents such that particle coagulation is prevented but formation of PCMA nanoparticles is permitted.

Abstract: Various methods and systems for facilitating online shopping at multiple retailer websites using a single login identifier are provided. The techniques disclosed herein allow prospective consumers to access various retailer websites on the Internet without the need to remember multiple logins and passwords or log into such retailer websites each time the consumers uses a new electronic device. The prospective consumers may log into a common website, such as a social networking website using a single user identifier and password. An example method for facilitating online shopping at multiple retailer websites using a single login identifier comprises receipt of the login information that corresponds to one or more login websites from a user device. The method may further include retrieving an internal user login identifier based on the received login information.

Abstract: A teaching aid comprising a plurality of counting elements, different counting elements being used to represent different powers of number, such that, when operating in base 10: (i) a first counting element incorporates a representation of a single unit or symbol; (ii) a second counting element incorporates a representation showing ten of the units or symbols shown on the first counting element; (iii) a third counting element incorporates a representation showing ten of the second counting elements; (iv) a fourth counting element incorporates a representation of ten of the third counting element; and so on.
