Patent CA-2109557-A1 (CA)
Title: Auto-piercing vaporizer adaptor
Inventor: LAVIMODIERE MAURICE
IPC: A61M16/18
Filed: 1993-11-19
Abstract: ABSTRACT A novel and useful adaptor for anaesthetic vaporizers is illustrated in which a sealed especially prepared refill bottle is placed with its coded cap in a cavity on a rotating body and is rotated into an inverted position, while a cam within the rotating body pulls the bottle onto sharp tubes and the bottle is pierced. Fluid then flows through aligned channels through the rotating body into a main body of the adaptor, and hence into the vaporizer. Equalizing air flows in the opposite direction. Major advantages include that no fluid may leave the vaporizer without a bottle being in position, and no bottle may be pierced unless it is coded correctly to fit into the adaptor; hence there are no open fluids during surgical procedure, and only the correct anaesthetic may be used. Additionally, a yoke on the bottle holds the bottle firmly enough that it may be left unattended, so that an additional bottle may be rotated into position to feed a full vaporizer and hence may serve as a reservoir, reducing the human attention required to deliverlarge amounts of anaesthetic during long surgery.

Title: Electron detector device for spectroscopic analyses of surfaces under x-ray excitation
Inventor: GOULON JOSE
IPC: G01N23/227
Filed: 1991-09-17
Abstract: 2118921 9306470 PCTABS00021 This invention concerns an electron detector device for spectroscopic analyses of surfaces under monochromatic X-ray excitation, this detector comprising: (i) a silicon diode (9) which is able to detect with a gain ã 1 accelerated secondary electrons; (ii) a microchannel plate (5) to pre-amplify the conversion photoelectrons emitted by the sample (1), and which is used at extremely low gain but with excellent linearity characteristics. The key component is a cooled Si-diode made of high resistivity n-type silicon with an ion implanted p+ layer (11) which is about 1300 Å thick. Its performances in detecting energetic electrons result from the absence of additional dead layers (passivated SiO2 or protective aluminium coating), only a few aluminium strips (14) being designed to optimize the charge collection. A different method exploiting the excellent performances of this detector but requiring two successive scans, allows to discriminate the contribution of the surface sensitive conversion photoelectrons against the radiative contribution, i.e. that of the X-ray fluorescence emission which contains structural information on the bulk sample.

Title: Dual mode portable digital signal transmit/receive device
Inventor: AUVRAY GERARD
IPC: H04W88/06
Filed: 1994-06-23
Abstract: The invention relates to a portable, dual-mode digital radio communication device allowing communications, on the one hand via a terrestrial network (first mode) and, on the other hand, via a satellite network (second mode). This device comprises means (215) for synthesising a first modulation frequency (213i) for modulating (211i, 211Q) the signals transmitted in the two modes, and a second transposition frequency (229) used for demodulating (228i, 228Q) the signals received in the said two modes, and means (245) for dividing the said second transposition frequency (229) delivering a third transposition frequency (244) for demodulating (241) signals received in one of the said modes employing a signal reception frequency band which is very far from the other frequency bands used. Thus it is possible, from a single pure synthesised carrier (229), in a first mode, to perform transposition with direct conversion and, in the second mode, to perform transposition to intermediate frequency followed by the same transposition with direct conversion. <IMAGE>

Patent CA-2127611-A1 (CA)
Title: Portable radio frequency enclosure for a smart card
Inventor: MANDELBAUM RICHARD
IPC: G07B15/00
Filed: 1994-07-07
Abstract: A pocket-size jacket or enclosure for a smart card is provided for facilitating two-way radio frequency read/write communications with a remotely associated interrogation station. The jacket includes a sleeve-like opening adapted to receive and position a smart card for providing power from the jacket to the card and also for enabling read/write communications between the card and the associated interrogation station. Power for circuitry both within the jacket and on the smart card is provided by an internal battery operated power supply in the jacket. Normally held in the off-state, radiated energy from an interrogation site associated with the interrogation station turns on the jacket's internal power supply when the smartcard/jacket combination is within a few feet of the radiation source at the interrogation site. A holder of the smart card/jacket combination is thus able to conduct a data transaction with the interrogation station either while standing near or moving past the interrogation site for such station. When the smart card/jacket combination is outside of the field of the radiated energy from the interrogation site, power to all the circuitry in the jacket and the card are turned off, thereby providing an extended operating life for the battery operated power supply.
