Abstract:
A method and system for selecting and connecting to an access point in a wireless network of devices, such as a Bluetooth network. Initially, an initiator device is preconfigured with a list of available access point addresses. The initiator device broadcasts an inquiry message that is received by available wireless devices which, in turn, respond with their respective addresses, occupancy level and device classification. The initiator device compares the respondent addresses with the preconfigured access point addresses and connects to a match, thus terminating the inquiry, provided certain fitness functions are satisfied. The fitness functions might include such considerations as occupancy rate, device classification, signal strength, or physical distance of separation. The list of addresses on the initiator device is updated automatically upon connecting with a network server whenever a new device is added or an old one removed from the network server's access point address list.

Abstract:
The barrier properties of a water soluble gas barrier material are improved if the material is blended with a nanoparticle calcium carbonate having a size of from 10 to 250 nanometers. The barrier material is on a substrate to provide a substrate with gas barrier properties. A layer of heat sealable material may be applied to the exposed surface of the barrier material. A method for making the barrier coated substrate is disclosed.

Abstract:
An active matrix display panel comprises a substrate, array of pixel circuits being arranged in a matrix of at least one column and a plurality of rows on the substrate, each pixel circuit comprising a light-emitting element, capable of emitting light of an intensity determined by the value of a current passed through it, and at least one column line, each column line arranged to conduct a reference current, provided by a current driving circuit, when connected to the panel. The pixel circuits in a column are divided into a plurality of groups of at least one pixel circuit. The active matrix display panel comprises at least one current mirror circuit associated with a first group, comprising a first current mirror, arranged to mirror a reference current flowing through a column line to a first current mirror output. Each pixel circuit in the first group comprises at least a first current-memory stage, having an output terminal connected to the light-emitting element, wherein the first current-memory stage is capable of drawing a current determined at least partly by the current mirrored to the first current mirror output through the output terminal. Each current mirror circuit comprises at least one additional current mirror, arranged to mirror a reference current flowing through an associated column line to an additional current mirror output, wherein each additional current mirror output is connected in parallel to the first current mirror output.
Abstract:
Each pixel of an active matrix electroluminescent display device has a first amorphous silicon drive transistor for intermittently driving a current through the display element and a second amorphous silicon drive transistor for intermittently driving a current through the display element. The aging effect of amorphous silicon TFTs can be reduced by sharing the driving of the display element between two drive transistors. Providing a duty cycle reduces the on-time for each drive transistor, but also provides a period during which there can be some recovery of the TFT characteristics.
Abstract:
An active matrix display device uses an amorphous silicon drive transistor for driving a current through an LED display element. First and second capacitors are connected in series between the gate and source of the drive transistor, with a data input to the pixel provided to the junction between the first and second capacitors. The second capacitor is charged to a pixel data voltage, and a drive transistor threshold voltage is stored on the first capacitor. This pixel arrangement enables a threshold voltage to be stored on the first capacitor, and this can be done each time the pixel is addressed, thereby compensating for age-related changes in the threshold voltage.

The invention, in various embodiments, provides systems and methods directed to tiered delivery of content to viewers. At each tier of the delivery process, content providers and/or authors may modify and/or customize a portion of the content based, at least in part, on tags associated with the content and user profiles of the viewers. In particular, the invention includes a method for providing content over a network from a provider to a plurality of user groups, including a first user group and a second user group, comprising managing and publishing the content, from the provider, being provided to the first user group, receiving and managing, by at least one member of the first user group, the published content, identifying, by at least one member of the first user group, a second user group for receiving the content, the second user group being different from the first user group; accessing, by at least one member of the second user group, the content; and tagging, by at least one of the provider and one member of the first user group, one or more portions of the content with one or more tags, each tag being associated with at least one portion of the content.

A colour electroluminescent, EL, display device comprising an array of pixels (11) each comprising sub-pixels (1) of two or more colours (R, G, B). For at least one of the colours (R, G, B), the pixel (11) comprises a first sub-pixel (RL, GL, BL) comprising a first EL material and a second sub-pixel (Rc, Gc, Bc) comprising a second EL material.
