Title: Metatarsal safety guard for footwear
Inventor: BISSON MICHEL
IPC: A43B7/32
Filed: 1999-01-26
Granted: 2004-01-06
Abstract: A metatarsal guard for footwear comprises an arched body which covers a dorsal surface of a wearer's metatarsal foot area. The arched body has lateral bottom edges for engaging a footwear sole to transmit loads from the arched body to the footwear sole. Slits are defined in a rear portion of the arched body so as to form a longitudinally extending central T-shaped tongue and two longitudinally extending lateral tongues in order to increase the flexibility of the metatarsal guard. The T-shaped tongue has a rear edge extending in a concave curved line transversally of the footwear so as to prevent transmission of punctual loads to the wearer's foot. By optimizing the number and the configuration of the tongues, both the wearer's comfort and protection are maximized.

Title: System for teleconferencing in which collaboration types and participants by names or icons are selected by a participant of the teleconference
Inventor: BURNS EMMETT R
IPC: H04L12/18
Filed: 1994-10-03
Granted: 2001-07-24
Abstract: A multimedia collaboration system that integrates separate real-time and asynchronous networks--the former for real-time audio and video, and the latter for control signals and textual, graphical and other data--in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations and their interconnecting LANs and WANs. In a particular preferred embodiment, a plurality of geographically dispersed multimedia LANs are interconnected by a WAN. The demands made on the WAN are significantly reduced by employing multi-hopping techniques, including dynamically avoiding the unnecessary decompression of data at intermediate hops, and exploiting video mosaicing, cut-and-paste and audio mixing technologies so that significantly fewer wide area transmission paths are required while maintaining the high quality of the transmitted audio/video.

Abstract: A method of printing an ink or meltable ink layer which comprises dyes or pigments or other colorants. The ink or ink melt layer comprises compounds with functional groups capable of reacting with active hydrogen, and compounds with functional groups containing active hydrogen, or functional groups capable of conversion to active hydrogen containing groups.
