Abstract: This disclosure relates to a projection system in which images are projected onto a surface at close proximity to the surface. The projection systems comprise a projection portion, an attachment portion, and a stand. The systems can further comprise a film that is placed onto the surface where the image will be projected. Methods are also disclosed for the use of such systems to attain a desired behavior in an individual such as a child.

Abstract: A process for the extraction of alumina from an aluminum-bearing ore or concentrate, comprising the steps of leaching the aluminum-bearing ore or concentrate with a lixiviant of hydrochloric acid and magnesium chloride at atmospheric pressure at a temperature of from 90° C. to the boiling point of the solution and at an Eh of at least 200 mV. After a liquid/solids separation step, the solution obtained is subjected to steps for removal of iron and for recovery of alumina.

Abstract: A method is provided for analysing the self-similarity of an audio file. The method involves obtaining the audio spectrum envelope data of an audio file to be analysed; performing a clustering operation on the spectrum envelope data to produce a clustered set of data; for a first portion of the clustered data, performing a string matching operation on at least one other portion of the clustered data; and based on the results of the string matching operation, determining the at least one other portion of the clustered data most similar to said first portion of the clustered data. There is also provided a method of repairing an audio stream received over a network using similarity data to replace damaged or missing portions of data with similar “good” portions of data.

Abstract: A broadband digital video recorder (BDVR) system allows cable or satellite television (TV) viewers to cause a copy of a selected TV show to be downloaded via a broadband Internet network and stored for viewing on a designated computer or a portable media player. Television viewers make a selection of a TV show to record using their remote control device. In response, the BDVR system causes a copy of a video file corresponding to the selected television show to be automatically downloaded from a remote server to the user's computer over a broadband Internet connection. Users may conveniently select a television show to record via a conventional television network but automatically download a digital video file corresponding to the television show to their computer via a broadband Internet network without complicated user interaction and without searching for the video files on the Internet.

Abstract: This invention provides novel devices and methods for the heating of air with solar radiant energy. The devices of the present invention feature a housing partitioned into essentially isolated sections wherein the sections are in fluid communication with each other through a plurality of channels located within the partitions. The two unique features of the invention, essentially isolated sections and partitions comprising a plurality of channels, increase the temperature achieved by the solar heater by 1) creating multiple, sequential sections that function independently of each other providing a higher starting temperature in each section and, therefore, a higher final temperature, 2) providing second means of heating the air within the channels located within the partitions and, 3) by virtually eliminating the mixing of incoming cold air with the heated air of the solar air heater.

Abstract: A closure valve for the filler neck of a vehicle fuel tank includes a plastic ball with a vapor impermeable plate attached to it to form part of its surface. The ball is held between a carrier on the inside and a seal carrier on the outside, the seal carrier being held against the ball by a screw cap, a spring washer and a vapor seal. When the valve is closed the plate, the seal carrier, the vapor seal and ring seals form a relatively impermeable barrier covering the end of the fuel filler pipe and preventing the escape of significant amounts of fuel vapor.
