| 20080294729 | EMAIL OBJECT FOR OPEN MOBILE ALLIANCE DATA SYNCHRONIZATION USAGE - An email object is provided that fulfills requirements defined in the OMA MEM Enabler, where email messages are represented as extensible markup language documents. Filters created using XPath allow an email client to indicate what email messages are to be advertised as new and later downloaded. Table of content information can also be provided without the need for downloading an entire email object first, as well as additional information about each body part. Therefore, referencing body parts for downloading email body parts step-by-step or for use in a reply/forward without download use case, as well as allowing for the downloading of alternative content (e.g., content-adaptation) is provided. Data synchronization protocols are used to allow the email client to keep an equivalence relationship between main email storage on the email server and local mail storage on the email client side when transferring email messages between the email client and email server. | 11-27-2008 |
| 20090106437 | Method and device for handling different addressing schemes in session initiation protocol communication - A method including sending a request for a Session Initiation Protocol (SIP) service, the request including at least one Universal Resource Identifier (URI) according to a first addressing scheme. The method further includes receiving a response including the URI of the first addressing scheme, a corresponding SIP URI for each URI of the first addressing scheme, and information associating each URI of the first addressing scheme with the corresponding SIP URI. The method further includes mapping each SIP URI to the corresponding URI of the first addressing scheme on the basis of the associating information. A device and a computer program product relating to the method are also described. | 04-23-2009 |

| 20080277718 | 1T MEMS scalable memory cell - This invention relates to the use of a gate dielectric placed under the mobile gate electrode of MOS transistor, without the need of a conductive floating gate. The invention exploits the electromechanical hysteretic behavior of the mobile gate when down contacting (pull-in) and up separating (pull-out) from the gate dielectric, based on the (non)equilibrium between electrical and elastic forces. | 11-13-2008 |
| 20100140589 | FERROELECTRIC TUNNEL FET SWITCH AND MEMORY - A Ferroelectric tunnel FET switch as ultra-steep (abrupt) switch with subthreshold swing better than the MOSFET limit of 60 mV/decade at room temperature combining two key principles: ferroelectric gate stack and band-to-band tunneling in gated p-i-n junction, wherein the ferroelectric material included in the gate stack creates, due to dipole polarization with increasing gate voltage, a positive feedback in the capacitive coupling that controls the band-to-band (BTB) tunneling at the source junction of a silicon p-i-n reversed bias structure, wherein the combined effect of BTB tunneling and ferroelectric negative capacitance offers more abrupt off-on and on-off transitions in the present proposed Ferroelectric tunnel FET than for any reported tunnel FET or any reported ferroelectric FET. | 06-10-2010 |
| 20100171569 | ACTIVE DOUBLE OR MULTI GATE MICRO-ELECTRO-MECHANICAL DEVICE WITH BUILT-IN TRANSISTOR - The present invention exploits the combination of the amplification, provided by the integration of a FET (or any other active device with two or more terminals), with the signal modulation, provided by the MEM resonator, to build a MEM resonator with built-in transistor (hereafter called active MEM resonator). In these devices, a mechanical displacement is converted into a current modulation and depending on the active MEM resonator geometry, number of gates and bias conditions it is possible to selectively amplify an applied signal. This invention integrates proposes to integrate transistor and micro-electro-mechanical resonator operation in a device with a single body and multiple surrounding gates for improved performance, control and functionality. Moreover, under certain conditions, an active resonator can serve as DC-AC converter and provide at the output an AC signal corresponding to its mechanical resonance frequency. | 07-08-2010 |

| 20090072279 | Capacitor-less memory and abrupt switch based on hysteresis characteristics in punch-through impact ionization mos transistor (PI-MOS) - The present invention exploits the impact ionization induced by drain voltage increase and the onset of a bipolar parasitic in an Ω-gate field effect metal oxide insulator transistor (called PI-MOS), in order to obtain a memory effect and abrupt current switching. | 03-19-2009 |
| 20090146194 | SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE - The local bending of a silicon nanowire induces tensile strain in the wire due to the stretching of the silicon lattice. This in turn enhances the mobility of the free carriers (electrons) in the direction of transport along the wire. Thus, for example, when Gate-All-Around MOSFETs are fabricated along the nanowire, the mobility enhancement will translate into an improvement in the performance (current drive, speed) of the silicon nanowire MOSFETs. In summary, a semiconductor device comprises a substrate and a nanowire in connection with the substrate at a drain and at a source region, and the nanowire is bent to achieve enhanced mobility of charge carriers. | 06-11-2009 |

| 20110282859 | IDENTIFYING UNIVERSAL RESOURCE LOCATOR REWRITING RULES - A computer-implemented process for identifying universal resource locator rewriting rules may receive input of universal resource locators of an application, to form received universal resource locators, may represent the received universal resource locators in a specialized graph and may apply analysis algorithms and heuristics to properties of the specialized graph. The computer-implemented process may further identify universal resource locator rewriting patterns using the specialized graph to form detected patterns and may generate rewrite rules corresponding to the detected patterns. | 11-17-2011 |
