Patent CA-2280696-A1 (CA)
Inventor: GREEP DARCY W
IPC: A61B18/10
Filed: 1998-06-02
Abstract: An electrosurgical electrode member for performing operative procedures includes a conducting electrode having a main body (22') configured to communicate radio-frequency electrical energy to patient tissue.  The main body has a sharpened portion (23'), such as an elongated edge or point, with a width of approximately 0.2 millimeters or less. The sharpened portion concentrates the radio-frequency electrical energy transferred from the main body to the patient tissue. In one embodiment, a non-stick insulating coating (20') covers the main body of the electrode including the sharpened portion. The insulating coating has a thickness to permit transmission of the radio-frequency electrical energy from the main body to the patient tissue by capacitive coupling. In an alternative embodiment, an operative portion of the sharpened portion extends outwardly from beneath the insulating coating.

Title: A multi-user communication system architecture with distributed transmitters
Inventor: MILLER DAVID S
IPC: H04B1/707
Filed: 1998-03-04
Abstract: A new signal processing architecture for base stations and gateways (124, 126) used in spread spectrum communication systems (100) that simplifies data transfer, reduces required bus capacity, and does not require special synchronization of signals that are to be combined.  A series of transmission modules (508l-508M) are used to transfer data to corresponding ones of a series of analog transmitters (412l-412M) used to form communication circuits for each system user. Each transmission module (508l-508M) employs a series of encoders (502MR) and modulators (504MS) to form spread communication signals, using appropriate PN spreading codes. Spread spectrum communication signals from each module (508) for each system user (D), are summed together (510l-510M) and transferred to a single analog transmitter (412) associated with that module. The signals being combined are automatically synchronized by common timing signals used for elements within each module. The number of processing elements within each module is such that at least one processing path is available for each user or user channel over which it is desired to transmit information through the connected analog transmitter (412l-412M). Data is output from the modules (508l-508M) at a greatly reduced transfer rate which can be more easily accommodated using current technology. This is very useful for satellite based communication systems, or high capacity cellular systems, and this system architecture can be accomplished cost effectively using a series of easily manufactured circuit modules.

Patent CA-2288950-A1 (CA)
Title: Nurse receiver header for air seeders
Inventor: HUNDEBY DAVID ROBERT
IPC: A01C7/04
Filed: 1999-11-04
Abstract: A nurse receiver header for an agricultural planting implement is cooperable with a nurse mechanism that conveys a stream of seeds entrained in an air stream from a central hopper. A receiver is positioned at the planting mechanism to receive the seeds entrained in the air stream and accumulate a supply of the seeds for utilization by the associated planting mechanism. The receiver header may include a vent for dissipating the air stream when receiving the seeds for distribution to the receiver. The vent is provided with a hood to keep contaminants from entering the vent and passing into the planting mechanism. The receiver header is positioned so that an appropriate supply of seeds for the planting mechanism fills the tube between the receiver header and the receiver including the vent, resulting in a decreased volume of discharged air for the air stream and a diminished ability for the nurse mechanism to convey seeds. The receiver header can be configured to service multiple receivers. The receiver header is mounted at an angle inclined to the vertical when in an operating position such that the receiver header can be rotated through an angle in the range of 70 - 110 degrees to a transport position without inverting the receiver header, thereby retaining the seeds accumulated in the receiver.

Title: Apparatus and method for determining a person's sobriety
Inventor: GAMMENTHALER ROBERT SCOTT
IPC: G01N33/497
Filed: 1999-08-12
Abstract: An apparatus and method for determining the concentration of alcohol present in a gaseous mixture wherein an electronic device employing a fuel cell (24) determines the concentration of al-cohol present in the gaseous mixture is disclosed.  In particular, the device may be used to determine a person's sobriety by determining alcohol con-centration in a breath sample exhaled by the same person. To determine alcohol concentration, the device must be able to accurately determine the volume of breath in the breath sample. The de-vice controls the volume of the breath sample by measuring the pressure of the breath flow through the device and, in response to the pressure sensed by pressure sensor (16), electronically controlling (22) a valve (20) diverting a portion of the breath flow into the fuel cell (24). Invention functions as sobriety interlock (40) for a machine where the machine remains disabled unless the operator is first determined to have an alcohol concentra-tion below a predetermined level.

Inventor: TRAVASSOS LUIZ RODOLPHO RAJA G
IPC: C07K14/44
Filed: 1998-02-16
Abstract: A chemiluminescent (CL)-ELISA method with purified and complex antigens of Trypanosoma cruzi is proposed for the specific and sensitive diagnosis of Chagas' disease in patients and blood bank samples. A trypomastigote specific antigen (A \A T) together with an epimastigote extract (EpEx), used as a control of sensitivity, are the preparations used. The high sensitivity of the CL-ELISA method permits the use of extremely small amounts of antigen and allows a serum dilution in routine tests as high as 1:2,000, thus reducing the nonspecific or false-positive reactions to a minimum. The use of the A \A T purified antigen eliminates cross-reactivities with other infectious agents, detects active infection, and serves to monitor chemotherapy in chronic patients. The use of the EpEx antigenic preparation not only confirms the positive results with A \A T but also, in case of discrepancy suggests other infections such as leishmaniasis. In comparison with current tests used in major blood banks, the CL-ELISA method with A \A T and EpEx antigens, tested in parallel, proved to be clearly superior either by eliminating indeterminate results or by increasing the statistics of diagnosed positive samples.

Abstract: There is disclosed a liquid supply method in which a bubble is prevented from being retained or accumulated in a communication part. An upper wall surface of a joint pipe for connecting a negative pressure control chamber container to an ink container is inclined upward to the ink container from the negative pressure control chamber container. Since the upper wall surface of the joint pipe is inclined, the bubble flows into the ink container without being retained or accumulated on the upper wall surface of the joint pipe during gas-liquid exchange.
