Patent number: 11959860Abstract: The present document describes a method for the detection of off-flavor maple syrup made from buddy maple sap or maple sap contaminated with buddy maple sap, or off-flavor maple sap. The method involves the measurement of a spectrophotometric property of a nanoparticle reactive with a buddy maple sample having a size of from about 1 nm to about 250 nm contacting a maple syrup or maple sap sample. A change in the spectrophotometric property is associated with an off-flavor maple syrup or maple sap sample, and no change in the spectrophotometric property is associated with a good flavor maple syrup or maple sap sample.Type: GrantFiled: May 2, 2019Date of Patent: April 16, 2024Assignee: PRODUCTEURS ET PRODUCTRICES ACÉRICOLES DU QUÉBECInventors: Jean-Francois Masson, Julie Barbeau

Patent number: 9850842Abstract: A controller for a common-rail injection system includes a plurality of fuel injectors, a common fuel supply line for the fuel injectors, a high-pressure pump for supplying the common fuel supply line with fuel, and a pressure sensor for determining the pressure in the common fuel supply line. A determination unit evaluates data of the pressure sensor and, from the pressure drop caused by an injection in the common fuel supply line, determines the fuel quantity actually injected during this injection or a value derived therefrom. An adaption unit uses the results of the determination unit in order to adapt the actuation of the fuel injectors. The determination unit carries out at least one test injection, and the actually injected fuel quantity or a value derived therefrom is effected by way of the test injection or injections.Type: GrantFiled: April 18, 2014Date of Patent: December 26, 2017Assignee: Liebherr Machines Bulle SAInventors: Konrad Christ, Francois Masson, Richard Pirkl

Patent number: 9334823Abstract: A controller for an injection system having a plurality of fuel injectors includes a map controller. From a desired injection value, the map controller generates a control value for actuating a fuel injector with reference to a specified map. A determination unit determines the actual injection value for at least one injection made, and an adaption unit uses results from the determination unit in order to adapt actuation of the fuel injectors. The adaption unit determines an adaption value for injector actuation from the at least one actual injection value. In engine operation, the adaption unit receives the control values generated by the map controller as input. From this input, the adaption unit generates adapted actuation values as output by applying a mathematical function to the control values generated by the map controller. The at least one adaption value is included in the first mathematical function as parameter.Type: GrantFiled: April 18, 2014Date of Patent: May 10, 2016Assignee: Liebherr Machines Bulle SAInventors: Konrad Christ, Francois Masson, Richard Pirkl
