Patent CA-2330269-A1 (CA)
Inventor: HENIG YENIG
IPC: F01N13/02
Filed: 2001-01-05
Abstract: A method of monitoring exhaust gas flow through an exhaust system of an internal combustion engine comprising the steps of generating a flow efficiency value (K E), comparing the flow efficiency value to a reference efficiency value, and if the reference efficiency value is exceed by a predetermined amount, then setting a flow fault indicator flag. In one aspect of the invention, the flow efficiency value is generated as a ratio of the magnitude of the exhaust gas flow restriction, and the mass flux through the engine. The magnitude of the exhaust gas flow restriction is represented by the pressure drop across the exhaust system, and the mass flux through the engine is determined as a function of the mass airflow rate and exhaust gas density. The resulting flow efficiency value (K E) is a non-dimensional parameter that characterizes the level of restriction in the exhaust system independent of the engine operating conditions.

Title: Quadriphase spreading codes in code division multiple access communications
Inventor: POPOVIC BRANISLAV M
IPC: H04J13/18
Filed: 1999-06-11
Abstract: Optimal code sequences are generated for use in spreading and de-spreading functions in a code division multiple access (CDMA) communications system. In particular, a family of quadriphase spreading codes is employed that provides a maximal number of spreading codes to achieve a high capacity in the CDMA communications system while at the same time having a minimal peak cross-correlation between any two spreading codes within that family to ensure cross-correlation interference is kept at or below acceptable levels. That optimal quadriphase spreading code family is the S(2) family of four phase code sequences of length L = 2m-1, where m is an integer greater than or equal to 5. The size of the S(2) family of quaternary spreading codes is (L + 2)(L + 1)2, and the maximum cross-correlation is 1 + 4.sqroot.(L + 1). The spreading codes are preferably allocated to base stations using specific code subsets of the S(2) family having the same cross-correlation properties of the S(0) and/or S(1) family of codes.  Spreading codes are advantageously extended by one or more code symbols as necessary or otherwise desirable. For example, to support variable transmission rate services, it is desirable to employ spreading codes whose length may be expressed as an integer multiple of each spreading factor in the mobile communications system.  Since individual spreading codes have a length of 2m - 1, one code symbol is added to the generated spreading code.

Title: Pressure washer with duty cycle temperature controller and method
Inventor: PAULEY STEPHEN J
IPC: G05D23/19
Filed: 2001-07-23
Abstract: A pressure washer for use by an operator. A heat exchanger has a water input adapted to connect to a water source and has a water output providing discharge water. A water pump supples water to the heat. A temperature selector is responsive to operator. A burner in thermodynamic communication with the heat exchanger applies heat to the heat exchanger and the water in the heat exchanger. The burner has a fuel input connecting a fuel source to the burner. A fuel switch selectively allows fuel from the fuel source to be supplied to the combustion chamber via the fuel input. A duty cycle timer has a uniform duty cycle and is energized when water flows through the heat exchanger. The duty cycle timer is responsive to the temperature selection switch to vary its duty cycle as a function of the operator input provided to the temperature selector. The duty cycle timer controls the fuel switch to supply fuel to the combustion chamber according to the duty cycle of the duty cycle timer whereby the duty cycle timer controls the burner and thereby controls temperature of the water in the heat exchanger. Preferably, the duty cycle has a minimum on time to maintain burner efficiency.
