Title: Micrometric direct-write methods for patterning conductive material and applications to flat panel display repair
Inventor: AMRO NABIL
IPC: B81C99/00
Filed: 2005-02-25
Abstract: A new, low temperature method for directly writing conductive metal traces with micron and sub-micron sized features. In this method, a flat beam is used, such as an AFM cantilever, with or without a tip, to draw traces of metal precursor ink onto a substrate. The dimensions of the metal traces can be directly controlled by the geometry of the cantilever, so that one can controllably deposit traces from 1 micron to over 100 microns wide with microfabricated cantilevers. Cantilevers with sharp tips can be used to further shrink the minimum features sizes to sub-micron scale. The height of the features can be increased by building layers of similar or different material. To obtain highly conductive and robust patterns with this deposition method, two general ink formulation strategies were designed. The key component of both ink systems is nanoparticles with diameters less than 100 nm. Because nanoparticles typically have significantly lower melting points than the bulk material, one can fuse, sinter, or coalesce collections of discrete particles into continuous (poly)crystalline films at very low temperatures (less than about 300 ~C, and as low as about 120 ~C). In the first strategy, one can disperse hydrocarbon-capped nanoparticles in a suitable solvent, deposit them on a surface in the form of a pattern, and then anneal the film by heating to form continuous metallic patterns. In the second strategy, one can deliver metal compounds to the surface in the presence of a reducing matrix and then form nanoparticles in situ by heating that subsequently coalesce to form continuous metallic patterns. In studies with platinum and gold inks, both nanoparticle-based methods yield micron sized traces on glass and oxidized silicon that have low resistivity (4 microohm.cm), and excellent adhesion properties.

Title: Improving bone formation and preservation by surgically inducing an increase in osteoblast activity coupled with the effect of administering a bone anabolic agent
Inventor: VIGNERY AGNES
IPC: A61K38/22
Filed: 2005-05-12
Abstract: A method of inducing bone formation in a subject in need of such inducement comprises the steps of mechanically inducing an increase in osteoblast activity in the subject and elevating blood concentration of at least one bone anabolic agent in the subject. The method steps may be performed in any order, but in sufficient time proximity that the elevated concentration of the anabolic agent and the mechanically induced increase in osteoblast activity overlaps. The method may additionally comprise providing the subject with an elevated blood concentration of at least one antiresorptive agent, wherein the elevated concentration is sufficient to prevent resorption of new bone growth produced due to the osteoblast activity. Use of the method permits targeting of specific bones of the subject for bone production and preservation, faster bone production and earlier discontinuation of bone anabolic pharmaceuticals.  Kits adapted for performing the method are provided.

Abstract: A method and system for creating and authenticating a document are disclosed.  According to the method, a user of a document creation system is registered to ensure the creation of an authentic document. A document is then created having a user discernable portion and an encoded portion. The encoded portion includes identification data identifying the registered user of the document creation system, as well as contents data corresponding to at least part of the user discernable portion of the document, and authentication data. A  central record of the document is created, the record comprising data which corresponds at least partially to the data in the encoded portion of the document. To authenticate the document subsequently, an image of the encoded portion of the document is acquired, for example using fax machine or a camera of a mobile telephone and transmitted to an authentication centre. The data in the encoded portion of the document is extracted and the document is authenticated by comparing the extracted data with data in the respective central record. Preferably, the encoded portion of the document contains instructions relating to the authentication process for obtaining biometric data from the respective user of the document creation system. For example, the encoded portion of the document may comprise a password, and the document creator is contacted to generate a live voiceprint of the password to be compared with a stored voiceprint for verification purposes. A system for creating and authenticating a document by the above method are also disclosed.

Title: System and method for creating cheap efficient high-speed home networks
Inventor: MAYER YARON
IPC: H04L12/413
Filed: 2007-04-23
Abstract: Broadband connections of end users to the Internet are becoming more and more common today, and the most common types of these fast connections are ADSL and Cable modems. These connections are typically still very slow compared to the speeds that are expected in the next few years and typically also highly asymmetric and allow typically 750-2000 Kbit per second (most typically 1500 Kbit) for the downlink and typically for example 96Kbit or 128Kbit per second for the uplink (although standard ADSL can in principle support up to 8Mbit per second download speed and up to 800Kbit per second upload speed), based on the assumption that most users download much more data than they upload. However, for many users these limitations are highly undesirable, and these are for example home users or small businesses or organizations who want to use the connection also for example for VOIP (voice over IP) communications and/or Video-over IP communications and/or conferences and/or for example running web servers and/or for example various p2p applications, and in fact the low uplink also many times slows down the downlink due to the overhead needed for dealing with relatively small packets, so that any additional uplink by the user can severely limit the real downlink that can be achieved below the downlink bandwidth which the user is paying for.  Actually ADSL is beginning to be replaced in some places by VDSL where the distance to the nearest street switchboard is about 1.2 Kilometers or less, which in principle allows up to 52 Mbit per second Download speed and up to 16 Mbit per Second Upload speed. However, these modems are expensive and are only slowly entering the market and only in a few countries. On the other hand there is no need to upgrade typical cable modems for enabling faster speeds, such as for example 20Mbit downlink and 2Mbit uplink, as is offered for example in France, when the ISPs start offering such speeds - since the typical common cable modem is already capable of such speeds. The present invention enables an improved Ethernet-over-coax solution which enables using one or a few very high speed modems, each for multiple users or apartments, preferably in combination with very cheap and very fast home networks (offering preferably at least up to 100Mbit per second for each computer, preferably at full duplex), preferably based on the Cable TV coax cables, so that multiple computers can share the same internet connection for example in the same apartment and/or communicate between themselves. This preferably includes using a different frequency for the Ethernet-over coax channel for each computer in the apartment. Also shown are for example improved home networks using the second set of normally unused 2 phone wires and for example some improvement in HPNA networks, such as for example using HPNA also to connect between the street switchboard and the home or office instead of having to use also for example an ADSL or VDSL modem.
