Abstract: The present invention relates to a housing clamp for a power tool housing, such as a drill, router, grinder, impact wrench, ratchet wrench, screwdriver, or other powered tool. The housing clamp includes a circumferential flange and recess that extends at an angle. When the housing clamp is installed, the housing clamp couples two portions of a power tool housing together. As the housing clamp is tightened onto the housing portions, the flange loads the housing with even pressure around its circumference providing a clamping load. The housing clamp provides even pressure around a large area at a working end of the tool, allowing the tool to be thinner in a dimensionally critical area.

Abstract: A surgical instrument may have multiple operating modes. An instrument operation mode may be selected from multiple operation modes, which may be preconfigured, dynamically updated, semi-dynamically updated, periodically updated, or preset. Multi-modal instrument operation may control the availability, access, level of use, level of interaction and/or support for one or more capabilities available through an instrument. A multi-modal surgical instrument may be fully operational in multiple modes of operation while varying one or more capabilities based on a mode of operation, such as one or more of sensors, communications, user-instrument interaction, displays, data storage, data access, data aggregation, data analytics, surgical support, feedback, surgical recommendations, etc.
