    摘要： A method in a combustion engine 100 for determining a desired fuel setting λ+. The method comprises configuring a fuel setting λ, determining a combustion engine parameter β in dependence of the configured fuel setting λ, wherein the combustion engine parameter is related to the fuel setting by a convex function relationship, and updating the fuel setting λ towards the desired fuel setting λ+, based on the determined combustion engine parameter β and on the convex function relationship between the fuel setting λ and the combustion engine parameter β.

    摘要： A replacement mobility assembly for a walk-behind, powered device (10) may include first and second drivable components, a mobility assembly frame, and an adaptation assembly. The powered device may be provided with an original mobility assembly (40) that is to be removed from coupling with a drive assembly and a chassis (15) of the powered device prior to installation of the replacement mobility assembly. The first and second drivable components may each be of a different type than corresponding drivable components of the original mobility assembly. The first and second drivable components may be operably coupled to the mobility assembly frame. The adaptation assembly may be configured to enable the mobility assembly frame to be operably coupled to the chassis and the first and second drivable components to be operably coupled to the drive assembly.

    摘要： A security device is provided that includes an electronic article surveillance tag that may be configured to resonate to provide a wireless response signal to a deactivator to trigger generation of a deactivation field. Further, the security device may include tamper detection circuitry which may include a tamper sensor configured to generate a tamper signal in response to detecting a tamper event, a deactivation sensor configured to generate a deactivation signal in response to detecting the deactivation field, and a sounder. In this regard, the tamper detection circuitry may be configured to deactivate the tamper detection circuitry in response to receiving the deactivation signal from the deactivation sensor such that receipt of the tamper signal after deactivation of the tamper detection circuitry does not trigger the sounder to emit the alarm.

    摘要： A method of producing a measuring tape may include providing a tape measure blade having a first end configured to extend from a housing and a second end configured to be wound on a reel assembly, defining a first non-critical region from the first end to a start of a critical region, defining a second non-critical region from the second end to an end of the critical region, and modifying a mass per unit length of a portion of the blade such that a mass per unit length of the first and second non-critical regions is less than a mass per unit length of the critical region.

    摘要： A method of interference mitigation may include receiving a desired signal from an asset of the system at an antenna assembly and associating the desired signal with relative phase distribution information based on a relative location of origin of the desired signal where the relative phase distribution information is predetermined for the antenna assembly. The method further includes receiving an interfering signal and associating the interfering signal with relative phase distribution information based on a relative location of origin of the interfering signal where the desired signal and the interfering signal forming a received signal set. The method further includes normalizing signals of the received signal set to respective relative phases associated with each respective relative location of origin, and performing interference cancellation of the interfering signal based on the normalized signals.

    摘要： A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around which a chain is rotatable. The guide bar (120) includes a first side plate (200) and a second side plate (210) facing each other and extending away from the housing (110) to a nose of the guide bar (120), the first and second side plates (200 and 210) each including an inner sidewall (224 and 222) facing inwardly toward each other. Each of the inner sidewalls (224 and 222) includes a recessed portion (230) at which material of the inner sidewalls (224 and 222) has been removed.
