Abstract: Handle configurations are disclosed for powered implements having a shaft, allowing the implements to be holdable by both hands of a user. An exemplary implement has an elongated shaft having first and second end portions. A first handhold is adjustably mounted to the shaft and extends outwardly therefrom. A second handhold is adjustably mounted either to the shaft or to an elongated member coupled to the shaft. The elongated member can include a mounting portion and a handle portion providing the second handhold. The mounting portion mounts to the first end portion at a mounting location. The first and second handholds allow operation of the implement by a user with arms in respective neutral arm positions and hands in respective neutral gripping positions. The elongated member allows transmission of a force applied to the second handhold by the user through the elongated member and to the elongated shaft at the mounting location.

Abstract: Relationships between components in an application and the services they provide are identified, including redundant caller-callee sequences. Specific components of interest are instrumented to obtain data when they execute. Data structures are created which identify the components and their dependencies on one other. To avoid excessive overhead costs, redundant dependencies are identified. A dependency data structure can be provided for each unique dependency. When repeated instances of a dependency are detected, the associated dependency data structure can be augmented with correlation data of the repeated instances, such as transaction identifiers and sequence identifiers. Sequence identifiers identify an order in which a component is called. A flag can be used to force the creation of a new dependency data structure, and a calling component's name can be used instead of a sequence identifier. Agents report the dependency data structures to a manager to provide graph data in a user interface.
