Patent number: 11344230Abstract: Embodiments of the invention disclosed herein are directed to articles of clothing that allow for monitoring of different analytes (e.g., electrolytes and molecules) in human sweat during fitness activity, while training, or simply in everyday life. The clothing includes a sensor system completely integrated in textile such that every sensing part is made of textile fibers. The clothing is able to control, collect, analyze, and expel the sweat over time. The textile sensor allows a spontaneous absorption of body sweat directly from the skin, while it is produced, using the hydrophilic natural properties of the textile. Then, once adsorbed, the flux of sweat is controlled and guided through the textile using a gradient of the textile's hydrophilic properties. The sweat guided through the textile is analyzed through an electrochemical sensor woven into the textile. Finally, the sweat is collected in a reservoir and expelled for evaporation.Type: GrantFiled: April 2, 2018Date of Patent: May 31, 2022Assignee: HFT Smart Sensors, IncorporatedInventors: Nicola Coppedè, Andrea Zappettini

Patent number: 7099069Abstract: An electro-optic (EO) device having a high-resistivity semiconducting crystal and a method of operating such a device. The local shielding of the externally applied field lowers the EO effect, which can be partially or completely inhibited particularly in the low-frequency regime, i.e., less than about 105 Hz. By holding a high-resistivity semiconducting crystal at a suitable temperature, EO response and efficiency are improved, in particular for light signals that are non-modulated or modulated at low frequencies. Preferably, the temperature at which the semiconducting crystal is held during functioning is between 50 and 150° C. Enhancement of the EO effect has been demonstrated also for EO devices operating at relatively large optical powers, i.e., larger than about 0.1 mW.Type: GrantFiled: December 18, 2001Date of Patent: August 29, 2006Assignee: Pirelli & C.

Patent number: 7014702Abstract: A heat treatment chamber (30) is provided comprising a treatment region containing a charge (5) of compound material comprising a plurality of n atomic species, each atomic species being associated with at least one gas species. The chamber (30) is placed in a furnace (7). The chamber has a gas permeable barrier, constituted by a plug (4) and wadding (6), which partially encloses the treatment region. The barrier serves as an effusive hole to inhibit, but not prevent, gas vapour release, thereby to elevate the gas vapour pressure in the treatment region. Application of inert gas through a valve (8) is also used to increase background pressure in the treatment region during heat treatment. The elevated gas pressures present in the treatment region during treatment are measurable in an absorption cell (3) adjacent to the treatment region. It is thus possible to monitor the gas pressures during heat treatment and thereby stop the heat treatment once a desired charge stoichiometry is achieved.Type: GrantFiled: May 30, 2001Date of Patent: March 21, 2006Assignee: Pirelli Cavi e Sistemi S.p.A.Inventors: Andrea Zappettini, Lucio Zanotti, Mingzheng Zha, Francesco Bissoli

Publication number: 20040052456Abstract: A crystal made of CdxZn1−xTe provides an electro-optical switch that performs consistently at high and low switching frequencies for signals of the 1000-1650 nm wavelength window. Preferably, a crystal of Cd0.9Zn0.1Te is driven with an electrical voltage to cause polarization rotation and switching action for a passing optical signal. Despite having a higher light absorption coefficient than CdTe:In, Cd0.9Zn0.1Te surprisingly exhibits a weak auto-inhibition effect, giving it better electro-optic performance when used in conjunction with optical wavelengths and optical powers characteristic of optical communication systems. Optical switch matrices and optical cross-connect switches in optical communication systems may effectively use Cd0.9Zn0.1Te crystals.Type: ApplicationFiled: September 12, 2003Publication date: March 18, 2004Inventors: Pierpaolo Boffi, Mario Martinelli, Antonella Milani, Andrea Zappettini

Patent number: 6584261Abstract: An apparatus for gating an optical signal comprising: an input stage arranged to receive and combine first and second optical control signals (ON, OFF) of first and second wavelengths, and an optical signal (SIGNAL IN) to be gated of a third wavelength. A gain medium is arranged to receive the signals SIGNAL IN, ON and OFF from the input stage. The gain medium (e.g. YAG) comprises a transition metal dopant (e.g. Cr4+) that has an excited state populatable by the first control signal and depopulatable by the second control signal to allow selective amplification of the optical signal to be gated by stimulated emission from the excited state responsive to the control signals. The amplification process has a very fast switch-on time that is several orders of magnitude faster than in prior art devices based on the rare earth dopant Er3+.Type: GrantFiled: November 20, 2001Date of Patent: June 24, 2003Assignee: Pirelli Cavi e Sistemi S.p.A.Inventors: Mario Martinelli, Andrea Zappettini
