  • Patent number: 11980955
    Abstract: Circular saws with lock assemblies are disclosed herein. The circular saws include a motor including a motor shaft configured to rotate about a shaft rotational axis. The circular saws also include an arbor configured to operatively attach a circular saw blade to the circular saw. The circular saws further include a switch configured to selectively apply an electric current to the motor and a switch lever configured to be selectively actuated, by a user of the circular saw and via an actuation force, to actuate the switch and direct the switch to apply the electric current to the motor. The lock assemblies include a switch lock, which defines a switch-locked configuration, in which the switch lock resists actuation of the switch lever by the user, and a switch-unlocked configuration, in which the switch lever is free to be actuated by the user.

  • Publication number: 20240142213
    Abstract: A measurement device includes a measurement head configured to capture dimensional measurement data of a measurement object. A guide structure is configured to move and guide at least one of the measurement head and the measurement object in a measurement volume of the measurement device. A measurement unit is configured to capture positional data of the guide structure based on which a pose of the measurement head can be calculated. Multiple temperature sensor units are configured to capture temperature data about the measurement volume. Each temperature sensor unit includes a carrier element, a temperature sensor connected to the carrier element, and a heating element connected to the carrier element. A control system is configured to process the dimensional measurement data and the positional data and, based on the temperature data, correct at least one of the dimensional measurement data and the positional data.

  • Publication number: 20230158702
    Abstract: Handheld circular saws with improved cutting capabilities are disclosed herein. The handheld circular saws include a motor and an arbor, which is configured to operatively attach a circular saw blade to the handheld circular saws. In some examples, the handheld circular saws include the circular saw blade, the circular saw blade has a blade diameter, the handheld circular saw has a maximum depth-of-cut, and a ratio of the maximum depth-of-cut to the blade diameter is at least 0.35 and at most 0.45. In some examples, the handheld circular saw includes a base plate that defines an arbor-facing side. In some such examples, at least 95% of the handheld circular saw is fully contained within a footprint of the handheld circular saw. In some such examples, an entirety of the handheld circular saw may be contained within a base plate width of the base plate.

  • Publication number: 20180259856
    Abstract: An optical projection unit includes first and second optical element modules. The first optical element module includes a first housing unit and a first optical element received within the first housing unit and having an optically used first region defining a first optical axis. The second optical element module is located adjacent to the first optical element module and includes a second optical element which defines a second optical axis of the optical projection unit. The first housing unit has a central first housing axis and an outer wall extending in a circumferential direction about the first housing axis. The first optical axis is laterally offset and/or inclined with respect to the first housing axis. The first housing axis is substantially collinear with the second optical axis.

  • Patent number: 7551375
    Abstract: The invention relates to processes for connecting an optical element of a microlithographic projection exposure apparatus to a mount, and also relates to an assembly. A process includes the following steps: forming a substance mixture at a processing temperature from at least a first component, which is solid at the processing temperature, and a second component, which is liquid at the processing temperature, the first component being dispersed in the second component, introducing the substance mixture in the unset state between the optical element and the mount, and setting the substance mixture so as to form a diffusion alloy from the first and second components.
