Patent CA-2276883-A1 (CA)
Inventor: DAVIES ROBERT J
IPC: H04B1/62
Filed: 1999-07-02
Abstract: A method and apparatus for harmonically upconverting a phase and/or amplitude modulated subcarrier signal to a higher frequency through a non-linear optical link is disclosed. The method requires that a bandpass signal, with a earner frequency at a submultiple of the desired radio transmission frequency, be frequency translated in a non-linear two-port device. To avoid the inherent distortion inflicted on the information signal in harmonic upconversion, a predistortion technique is outlined. This consists of phase compression in the case of a phase modulated signal, amplitude scaling in the case of amplitude only and combined phase-amplitude predistortion for QAM type signals. With predistortion on the subcarrier signal input to the non-linear two-port, the resulting upconverted signal may be transmitted in a standard form suitable for demodulation at the signal destination without special equipment.

Patent CA-2279898-A1 (CA)
Inventor: GELOTTE KARL M
IPC: C08F6/28
Filed: 1998-02-04
Abstract: A novel process has been developed for the treatment of cross-linked ethylenepropylene diene monomer (EPDM) elastomer material to decrease its residual peroxide levels. EPDM is used to form the seats and neck gaskets of metering valves used in metered-dose inhalers (MDI). For filled and inverted MDI units these EPDM components are in direct contact with the pharmaceutical formulation media. The process involves exposing the EPDM valve components to a solution of 2-mercaptoethanol, a chemical reducing agent. The 2mercaptoethanol greatly diminishes the residual peroxide levels in EPDM by reducing the peroxide functional groups to the corresponding hydroxyl groups. EPDM components treated in this manner have demonstrated very low peroxide levels and, consequently, greatly improved compatibility with the pharmaceutical formulation in the inhaler. An advantage of this approach is that the treated EPDM would likely retain its favorable physical properties and its good performance in metering valves. In this work 2-mercaptoethanol was used as the model reducing agent. It is believed, however, that similar positive results can be obtained using other reducing agents, notably other volatile compounds containing sulfur in one of its lower valence states (i.e. other thiol compounds or sulfur dioxide).

Title: Cloaking circuit for use in a radio frequency identification and method of cloaking rfid tags to increase interrogation reliability
Inventor: KRUEST JAMES R
IPC: B42D15/10
Filed: 1998-05-29
Abstract: The antenna of an RFID tag (100) is disconnected from the balance of the RFID  chip by means of a series switch (24) activated in response to a logic command, CLOAK. Activation of the switch (24) disconnects the antenna (16) of the RFID tag for the remainder of the chip and effects a high impedance resistance across the antenna terminals (12, 14). An RC circuit (36, 38) is charged by activation of the CLOAK signal and thereafter discharges during a predetermined time period as determined by a high impedance series antifuse leakage transistor (34). The antenna is thus disconnected for a time sufficient to allow the remaining RFID tags to be identified.

Analog telephone service is provided over a first twisted wire pair drop cable, while the high speed data service is provided over a second twisted wire pair drop cable. In an alternate embodiment, the BDT's cell based signal is transported to two separate terminals.  Analog telephone service is provided to a subscriber location from the first terminal, while high speed data service is provided to a second subscriber location from the second terminal. Yet another embodiment provides analog telephone and high speed data services from a single linecard located in an access multiplexor. The analog telephone and high speed data signals are generated on the linecard and combined using a diplexor. At the residence, a receiving diplexor is used to separate the combine signal. Still another embodiment generates a high speed data signal at an access multiplexor which contains a digital representation of the analog telephones signal. The high speed data signal is sent to the residence, where a receiving device generates an analog telephony signal and transmits the high speed data signal to appropriate terminal equipment.

Abstract: A vacuum-assisted venous drainage reservoir of cardiopulmonary bypass surgery with both hard and soft shell reservoirs. The system creates regulated negative pressure of approximately -70 to -25 mmHg within a sealed hard shell reservoir, or within a sealed housing surrounding a soft shell reservoir. The reservoir has a blood inlet for supplying blood removed from the patient and a blood outlet leading to an oxygenator. A  vacuum regulator subassembly for manually setting the predetermined desired vacuum, a valve subassembly for manually enabling and disabling the negative pressure, a pressure relief valve, and/or a vacuum stabilizer to reduce the severity of large changes in vacuum pressure may be provided. A flexible membrane in the hard shell reservoir may expand to contact the blood surface and reduce blood/air interactions. A  volume sensor for the hard shell reservoir may be used in a feedback loop for controlling the vacuum, circulation pump, or other device. A  piece of air-permeable in the venous return line enables the use of smaller cannulas suitable for minimally invasive surgery. The reservoir need not be positioned well below the patient as in conventional gravity venous drainage configurations, thus adding flexibility to the operation room layout and enabling a reduction in the required extracorporeal blood prime volume.
