Patent number: 10608699Abstract: Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Today's leading edge modulated sinusoidal wave wireless communication standards and systems achieve power efficiencies of 50 nJ/bit employing narrowband signaling schemes and traditional RF transceiver architectures. However, such designs severely limit the achievable energy efficiency, especially at lower data rates such as below 1 Mbps. Further, it is important that peak power consumption is supportable by common battery or energy harvesting technologies and long term power consumption neither leads to limited battery lifetimes or an inability for alternate energy sources to sustain them. Accordingly, it would be beneficial for next generation applications to exploit inventive transceiver structures and communication schemes in order to achieve the sub nJ per bit energy efficiencies required by next generation applications.Type: GrantFiled: May 31, 2016Date of Patent: March 31, 2020Assignee: Transfert Plus Societe en CommanditeInventors: Frederic Nabki, Dominic Deslandes, Mohammad Taherzadeh-Sani, Michiel Soer

Patent number: 10534137Abstract: Unlike most MEMS device configurations which simply switch between two positions in many optical devices the state of a MEMS mirror is important in all transition positions. It may determine the characteristics of an optical delay line system and by that an optical coherence tomography system in one application and in another the number of wavelength channels and the dynamic wavelength switching capabilities in the other. The role of the MEMS is essential and it is responsible for altering the paths of the different wavelengths in either device. It would be beneficial to improve the performance of such MEMS and thereby the performance of the optical components and optical systems they form part of. The inventors have established improvements to the design and implementation of such MEMS mirrors as well as optical waveguide technologies to in-plane optical processing as well as the mid infrared for optical spectroscopy.Type: GrantFiled: July 30, 2018Date of Patent: January 14, 2020Assignee: Transfert Plus Societe en CommanditeInventors: Michael Menard, Frederic Nabki, Mohamed Rahim, Jonathan Briere, Philippe-Olivier Beaulieu

Patent number: 10477469Abstract: Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2 V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction.Type: GrantFiled: January 24, 2019Date of Patent: November 12, 2019Assignee: Transfert Plus, Societe en CommanditeInventors: Frederic Nabki, Dominic Deslandes, Alexandre Desmarais, Anh-Kiet Vuong, Anis Bounif, Wang Yu Hao, William Pham

Patent number: 9917650Abstract: Photonic integration has primarily sought to exploit optical parallelism through wavelength division multiplexing whilst in many instances “brute-force” time division multiplexing offers benefits through reduced complexity and cost. However, photoreceivers are primarily the same now for operation at 10 Gb/s, 20 Gb/s, 40 Gb/s and above as 20 or 25 years ago and exploit the same optical detection—amplification—logic processing design. However, high speed low cost electronics ca be leveraged in conjunction with optical time sampling and logic to provide a new design paradigm. An incoming XGbs?1 optical data stream is sampled and processed by N photodetectors each operating at (X/N)Gbs?1 rather than the current direct XGbs?1 front-end of the prior art. Flexibility for the designer in establishing N within optical layer constraints, electronics capabilities etc.Type: GrantFiled: August 26, 2016Date of Patent: March 13, 2018Assignees: TRANSFERT PLUS, SOCIÉTÉ EN COMMANDITE, THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/ MCGILL UNIVERSITYInventors: Odile Liboiron-Ladouceur, Md.

Publication number: 20080286253Abstract: Compositions for the selective delivery of an agent comprising an uncrosslinked starch modified by an acidic group and an agent are described. The compositions are substantially resistant to degradation and thus result in no or substantially no release of the agent in a first environment, and are capable of degradation in a second environment thereby allowing release of the agent. The pKa of the acidic group of the uncrosslinked starch used is higher than the pH of the first environment and lower than or equal to the pH of the subsequent environment. Also described herein are methods of preparing the compositions, methods of using the compositions and the uncrosslinked starch modified by an acidic group, and corresponding commercial packages.Type: ApplicationFiled: February 9, 2005Publication date: November 20, 2008Applicant: Transfert Plus Societe En CommanditeInventors: Jérôme Mulhbacher, Mircea Alexandru Mateescu, Carmen Calinescu
