IPC: G01N21/86
Filed: 1994-08-26
Abstract: Abstract A video test strip reader uses a video imager or camera for viewing a viewing field containing reagent test strips each having test pads reacted with a specimen containing constituents of interest. The video imager produces an analog signal representing an image of the viewing field. An image handler coupled to the video imager converts or digitizes the analog signal into a digital signal representing the image and stores the image in the form of an array of pixels representing the image. Each pixel contains color information broken down into red, green or blue (RGB). A processor coupled to the image handler analyzes the array of pixels, determines the location and orientation of a test strip, identifies the test areas on the test strip, measures the corresponding test areas on the strip at the proper times and calculates the test results, such as the concentration of the constituents of interest in the specimen or other measurable properties of the specimen such as color or specific gravity, etc. Accordingly, the video test strip reader can simultaneously locate, color analyze and time track multiple test strips on the viewing field.

Patent CA-2146648-A1 (CA)
Title: Transmission network and filter therefor
Inventor: BROWN PAUL ANTHONY
IPC: H04B3/54
Filed: 1993-10-20
Abstract: A power transmission network (40) is disclosed which includes input means (52) for the input of telecommunication signals having carrier frequen-cies greater than 1MHz onto the network (40), and a means for removing similar speech and/or data signals from the network. Preferably a network conditioning element (52) is used which includes a low pass filter portion for filtering out a low frequency high amplitude mains power signal, and a coupling element for input and/or removal of telecommu-nication signals from the ne-twork. In this way both speech and data signals can be trans-mitted at carrier frequencies of greater than 1MHz along a standard electricity distribution and/or transmission network which when conditioned pro-vides a larger available spectrum per unit length of network and greater transmission capacity than previously known. The quies-cent noise level of the conditioned network is also much reduced thus permitting lower signal injection levels for a given signal-to-noise ratio and a consequential reduction in spurious radiation from the network.

Title: Spark plug with automatically adjustable gap
Inventor: CONWAY SCOTT R
IPC: H01T13/26
Filed: 1994-06-20
Abstract: In spark ignited engine configurations, it is common to provide a spark plug that has a spark gap that has dimension that will accommodate good starting capabilities for the engine. In some cases, this spark gap is larger than required for the engine to run efficiently, especially at high loads. As a result, the voltage required to bridge the gap when the engine is running at high loads is much higher than necessary and causes erosion of the electrode and a build up of deposits on the ground strap. Ultimately, this greatly reduces the life of the spark plug. The present invention provides a spark plug (10) that utilizes an adjusting means (50) that is connected to the electrode (42) of the spark plug (10) and functions to move the electrode (42) with respect to the ground strap (20) to adjust the gap (48) therebetween. The adjusting means (50) is responsive to the temperature of the spark plug (10) which will vary with engine loads or an increase in pressure within the combustion chamber (64).
