  • Patent number: 11733225
    Abstract: An oxygen sensor for a gas, coal, oil or wood fired kiln that is orders of magnitude cheaper than the current state of the art oxygen sensors. It uses a TiO2 tip sintered between and bridging a 1 mm spacing between a pair of 22 gauge Nichrome® series 90 round annealed resistance wires (0.64 mm diameter and having 0.648 Ohms/ft resistance). The Nichrome® 90 wires do not contact each other. One of the wires is a signal wire that resides down the center of an insulating sheath and the other wire is a ground wire that is wound around the outside of a high temperature ceramic insulating sleeve. The sensor needs no temperature compensation and exhibits an approximate 50,000 ohms of resistance change from a neutral (ambient) atmosphere and a fully reduced atmosphere.

  • Patent number: 11241591
    Abstract: An acoustic module with a transducer and a solid waveguide. The transducer and waveguide may be curved to focus the acoustic energy along a focal line. The transducer, the top surface of the waveguide and the bottom surface of the waveguide may extend along coaxial curves. The waveguide may include a recess closely receiving the transducer. The waveguide may include an integral skirt that provides a thermal mass. The acoustic module may include a space to accommodate thermal management options. For example, the acoustic module may include a heatsink, an active ventilation system and/or a phase change material. The ultrasound device may include a controller configured to perform a uniformity scan sweep during supply of operating power to the transducer. The uniformity scan sweep can extend through a frequency range that includes the operating point of the acoustic module and does not exceed an acceptable efficiency loss.

  • Patent number: 8820489
    Abstract: An electric motor for driving a vehicle wheel includes a parking brake that is selectively applied to provide a park brake condition. The parking brake is a clutch style brake and includes a sliding brake disk that is mounted for rotation with a motor shaft. A brake piston is used to move the sliding brake disk into engagement with a motor housing to achieve a park applied position. The parking brake is held in a release position by a hydraulic system that exerts a fluid pressure force against the brake piston. A resilient mechanism cooperates with the brake piston to apply the parking brake once the fluid pressure force is diminished.

  • Publication number: 20120080430
    Abstract: A cooking vessel with a selectively configurable condensation collector. In one configuration, the condensation collector collects condensation impeding it from reaching the content of the cooking vessel. In another configuration, condensation is allowed to reach the content of the cooking vessel. A movable reservoir can be configured to either be flush with the lid preventing condensation from reaching the reservoir or configured to form a gap between the reservoir wall and the lid so that condensation can collect in the reservoir. Alternatively, a condensation collector can be detachably connected to a cooking vessel lid so that when it is attached condensation collects and when it is detached condensation reaches the content of the vessel. Alternatively, a condensation collector can be permanently attached to a replacement cooking vessel lid that is swappable with a conventional cooking vessel lid.

  • Patent number: 7873614
    Abstract: Role is a comprehensive grouping mechanism. In a client-server directory system, roles transfer some of the complexity to the directory server. A role is defined by its role definition entry. Any client with appropriate access privileges can discover, identify and examine any role definition. A “managed” role is one that can be configured to provide search results similar to those available with a static grouping mechanism, i.e., to create a group entry that contains a list of members. Managed roles allow a user to create an explicit enumerated list of members. A managed role is a label stored with a directory entry.

  • Patent number: 7845445
    Abstract: An electric drive unit for a vehicle wheel includes an electric motor that powers a planetary drive having a first stage gear set and a second stage gear set. Each of the first and second stage gear sets includes a sun gear that is driven by a motor output shaft. Each of the first and second stage gear sets also includes a plurality of planet gears that are in meshing engagement with a respective one of the sun gears. The first and second stage gear sets share a common ring gear. A planet carrier of the second stage gear set provides driving output to a wheel shaft that drives the vehicle wheel.

  • Publication number: 20100096116
    Abstract: A heat diffuser for use with a cooking implement is disclosed. The heat diffuser may be positioned using its handle between a heat source and a cooking container to counteract high temperature zones within the cooking container. The diffuser thus aids in even heat distribution throughout a cookware container for more even cooking and provides the user with more control over the heat applied to the cookware container.

  • Publication number: 20090079278
    Abstract: A cooling jacket for an electric motor includes a plurality of jacket portions that are attached to each other to surround a motor stator. Each jacket portion is an extruded component that includes an outer peripheral wall and an inner peripheral wall spaced inwardly from the outer peripheral wall to form a cooling space between the inner and the outer peripheral walls. A plurality of connecting walls extends between the inner and the outer peripheral walls. The connecting walls cooperate with each other to define a plurality of discrete cooling passages within the cooling space of each jacket portion. First and second end caps are mounted to the plurality of jacket portions to enclose the plurality of discrete cooling passages such that a continuous cooling loop is provided through the plurality of jacket portions and the first and second end caps.

  • Publication number: 20080224428
    Abstract: A vehicle suspension includes a plurality of pneumatic suspension elements with each pneumatic suspension element being associated with one pneumatic control valve. A common manifold is fluidly connected to each of the pneumatic control valves. The manifold includes a supply valve that is connected to an air supply, an exhaust valve, and a single pressure sensor. The single pressure sensor is used to measure a pressure level at each of the pneumatic suspension elements. A controller cooperates with the manifold to individually adjust pressure levels of each of the pneumatic suspension elements based on the individually sensed pressure levels. The controller can use the sensed pressure levels to adjust suspension ride height, identify system leaks and isolate defective suspension elements, identify uneven pressure distribution, and to determine a load supported on the pneumatic suspension elements.
