摘要： A method of constructing an E-puck includes forming at least one trench into a lower substrate, depositing an electrode material onto the lower substrate and into the at least one trench, removing excess electrode material from the lower substrate to leave the electrode material within the at least one trench to form an electrode, and forming a dielectric on the lower substrate and the electrode. The electrode is between the lower substrate and the upper substrate. Forming the at least one trench into the lower substrate forms at least one standoff portion adjacent to the at least one trench and the at least one standoff portion reduces dishing of the electrode material during removal of the excess electrode material from the lower substrate.

摘要： Temperature sensing probes for sensing the temperature of a substrate based on fluorescence are disclosed. The temperature sensing probes include a fiber optic cable having at a cold end an optical interface and at a hot end a temperature sensing element for contacting a substrate. A sheath surrounds at least a portion of the hot end of the fiber optic cable. A retaining member securely and removably engages the sheath with a support member. The sheath forms a vacuum seal around the contact between the temperature sensing element and the substrate.

摘要： An exhaust gas heater system for an exhaust system of an internal combustion engine includes a housing and a heating element. The housing includes an outer peripheral wall disposed about a central axis and defining an interior hollow space configured to receive exhaust gas from an exhaust pipe of the exhaust system such that the exhaust gas flows through the interior hollow space. The heating element is positioned within the hollow space and including a first end and a second end. The heating element forms a zig-zag shape extending in a radial direction relative to the central axis.

摘要： A method of predicting temperature of at least one location in a fluid flow system that has a heating system for heating fluid. The method includes obtaining a mass flow rate of fluid flow of the fluid flow system, obtaining at least one of a fluid outlet temperature and a fluid inlet temperature of a heater of the heating system, obtaining power provided to the heater, and calculating temperature at the at least one location based on a model of the fluid flow system and the obtained mass flow rate, fluid outlet temperature, and fluid inlet temperature.

摘要： A control system for operating a heater includes a controller configured to determine an operational power level based on a measured performance characteristic of the heater, a power set-point, and a power control algorithm, determine a bake-out power level based on a measured leakage current at the heater, a leakage current threshold, and a moisture control algorithm, and select a power level to be applied to the heater. The selected power level is the lower power level from among the operational power level and the bake-out power level.

摘要： A heater includes a flow guide and electrical resistance heating elements. The flow guide defines a continuous geometric helicoid disposed about a longitudinal axis and defines perforations that extend in a longitudinal direction through a first longitudinal length of the geometric helicoid. The first longitudinal length is less than a full longitudinal length of the geometric helicoid. The electrical resistance heating elements extend through the perforations. For each electrical resistance heating element, a length of that electrical resistance heating element and a pitch of the geometric helicoid at a distal end of that electrical resistance heating element are such that the distal end of that electrical resistance heating element is a distance X from the geometric helicoid at the distal end of that electrical resistance heating element. The distance X is less than or equal to 40% of the pitch at the distal end of that electrical resistance heating element.

摘要： An exhaust gas heating unit for an engine includes a housing and a heating element. The housing includes a tubular peripheral wall and has an interior hollow space. The heating element has first and second ends and extends longitudinally therebetween to form a spiral shape within the interior hollow space. The heating element includes a thermally conductive sheath, an electrically conductive resistance element that extends longitudinally within the external sheath, and an electrically insulating material disposed about the resistance element between the resistance element and the sheath. A heat transfer member is positioned within the interior hollow space and is formed from one or more strips of thermally conductive material. The strips contact the external sheath at a plurality of locations between the first end and the second end. The heat transfer member has a corrugated shape that follows the spiral shape of the heating element.
