Patent CA-2165000-A1 (CA)
Title: Insect bait
Inventor: FELL RICHARD D
IPC: A01M1/20
Filed: 1995-12-12
Abstract: An insect bait specifically formulated for the biology, feeding behaviour and food preferences of carpenter ants preferably includes the following ingredients: sucrose and/or fructose sugars; alkali or alkaline earth salts such as sodium chloride, potassium chloride, magnesium chloride, and calcium chloride; urea; and amino acids and/or proteins. Ideally, the bait has a matrix material that has a gelatinous consistency, and, most preferably, the matrix material is agar. Fats and oils are not preferred by carpenter ants; therefore, the use of these materials in the insect bait should be minimized or eliminated. By combining an insecticide with the bait, the material is used to effectively control and eliminate carpenter ant infestations.
Patent CA-2167099-A1 (CA)
Title: Particulate analysis of fluid samples
Inventor: REENTS WILLIAM DAVID JR
IPC: G01N1/02
Filed: 1996-01-12
Abstract: The present invention provides apparatus and methods for analyzing the particulate content of liquid samples. In an exemplary embodiment, the invention relates to a particle-analyzing apparatus comprising a liquid removal portion and a particle analyzing portion. In the liquid removal portion, the apparatus comprises a droplet formation portion for generating a droplet-laden gas stream from a liquid sample to be analyzed. Communicating with the droplet formation portion is a liquid removal portion. The liquid removal portion receives the droplet-laden gas stream generated by the droplet formation portion and substantially removes the liquid from the received droplet-laden gas stream to create a particle-laden gas stream. The particle-laden gas stream is transported to a particle analyzer for evaluating the particles entrained in the particle-laden gas stream. Particle evaluation can range from rudimentary particle counting to more sophisticated real-time analysis of particle quantities and compositions.

Title: Methods of detecting and combating disorders of the central nervous system
Inventor: ROGERS SCOTT W
IPC: G01N33/53
Filed: 1994-08-10
Abstract: A method of screening a subject for a central nervous system disorder caused by autoimmune disease (e.g., an inflammatory seizure disorder) comprises collecting a sample from the subject and then detecting the presence or absence of anti-glutamate receptor autoantibodies (e.g., anti-GluR3 glutamate receptor autoantibodies) in the biological sample. The presence of such autoantibodies indicates the subject is afflicted with a central nervous system disorder caused by autoimmune disease. Methods of treating such disease by reducing the number of autoantibodies available to bind to glutamate receptors in the subject are also disclosed.

Title: Modem communication interoperability with call waiting services
Inventor: CIVANLAR MEHMET REHA
IPC: H04M3/428
Filed: 1996-03-08
Abstract: A novel modem communication method provides interoperability between modems and call waiting services. The method operates in conjunction with a first modem adapted for communications with a second modem over a telephonic communications link. Upon receipt of a call waiting alerting tone corresponding to a third party incoming call, the first modem sends the second modem a call waiting notification signal. In response to the call waiting notification signal, the second modem sends the first modem a call waiting acknowledgment signal, and the first and second modems enter an idle state. In the idle state, the modems remain connected to the telephonic communications link, but stop sending and receiving data. The first modem remains in the idle state until the third party incoming call is terminated, whereupon, in response to such termination, the first modem sends a resumption signal to the second modem. Upon receipt of the resumption signal, the second modem exits the idle state and resumes the sendingand receiving of data.
Patent CA-2176454-A1 (CA)
Title: Pacemaker pulse detection and artifact rejection
Inventor: DONEHOO ROBERT F
IPC: A61B5/366
Filed: 1996-05-13
Abstract: A method and apparatus for detecting a pacemaker pulse in an electrocardiogram signal (ECG signal) from characteristic artifacts introduced into said ECG signal by the filtering process to allow identification and removal of the pacemaker pulse from the ECG signal.  Upon detection of the pacemaker event, the amplitude threshold used in the detection of the QRS complex is raised to a higher level following the pacemaker pulse so that the characteristic artifacts do not exceed the threshold. The amplitude threshold is decayed to the normal QRS threshold level over a time interval determined in accordance with the characteristics of the filter which introduced the artifacts so that the artifacts will remain below the amplitude threshold.  This technique is desired since prior art techniques requiring removal of the pacemaker pulse and any artifacts associated with the pacemaker pulse before QRS complex detection also remove any QRS complexes  occurring in the blanking window.  By using a variable threshold, the amplitude of the QRS complex will exceed the threshold while the artifacts caused by the pacemaker pulse will remain below the threshold so that no blanking is necessary.
Patent CA-2178967-A1 (CA)
Title: Tree planting attachment
Inventor: KOSTKA PAUL
IPC: A01C5/04
Filed: 1996-09-10
Abstract: Planting tree seedlings, to the best of my knowledge, is mostly done manually. This invention will do four things by means of hydraulic cylinders, 1) provide a hole for the seedlings, 2) automatically plant tree seedlings, 3) tamper the seedlings after planting and, 4) provide nutrients to the newly planted seedlings.  The seedlings are manually loaded into individual compartments. The compartments are conveyed over a chute and the tree seedlings fall down the chute and into a hole in the ground which has been made by a hydraulic cylinder. After the seedlings are in, other tampering cylinders will pack the plant securely in the ground. As the tampering cylinders leave two holes near the newly planted tree seedlings, this invention will also distribute nutrients to either one or both sides of the seedlings. All of these components are mounted on a heavy, steel base and is attached to crawler-type equipment. All functions are electronically synchronized.
