The invention relates to a cutting tool apparatus comprising a tool head rotatingly drivable about an axis of rotation, which tool head has a tool slide adjustable along an adjustment axis and an electrical measuring device for detecting an adjustment path of the tool slide, and comprising an external display device which is mechanically and electrically releasably connectable to the tool head and has a display unit for displaying the adjustment path of the tool slide. In order to further develop the cutting tool apparatus such that its handling is simplified, it is proposed according to the invention that the display device is mechanically securable on the stationary tool head in order to set the tool slide and is automatically releasable from the tool head if a predeterminable rotational acceleration of the tool head is exceeded.

An electrical apparatus includes first and second battery interfaces disposed on a housing for electrically and mechanically connecting first and second battery packs in series. A controller is disposed within the housing and includes an apparatus microprocessor that receives first and second communication signals respectively outputted from respective microprocessors of the first and second battery packs. A first signal communication path communicates the first communication signal from the first battery pack microprocessor to the apparatus microprocessor by shifting a first voltage range of the first communication signal to a second voltage range that is suitable for inputting into the apparatus microprocessor. A second signal communication path communicates a third communication signal from the apparatus microprocessor to the first battery pack microprocessor by shifting the second voltage range of the third communication signal to a first voltage range that is suitable for inputting into the first battery pack microprocessor.

The present disclosure is directed to a cordless power tool vibration isolation system. A solution to negative impacts of vibration on a removable battery pack caused by operation of a cordless power tool. Isolating the battery pack from the power tool reduces wear and tear on the battery pack including the pack housing, the pack terminals and internal pack components. A battery pack interface of the power tool including a discrete interface housing that mates with the battery pack and a vibration isolation element that separates and isolates the combination of the discrete interface housing and the battery pack from the power tool and the power tool's associated motor induced vibrations.

A cutting tool includes: a cutting section having a cutting edge; a sensor provided in the cutting section; and a communication unit provided in the cutting section. The communication unit transmits, to a processing device provided outside the cutting tool, measurement information relating to measurement results of the sensor and including serial numbers corresponding to the measurement results after a timing of a start of cutting by the cutting edge.

An electrical device, such as a power tool, includes a first battery pack receptacle configured to receive a first battery pack and a second battery pack receptacle configured to receive a second battery pack. The second battery pack is electrically connected in a series-type configuration with the first battery pack. The electrical device also includes circuitry with an electronic processor. The circuitry is configured to alter a first signal output from the electronic processor to at least one selected from a group consisting of the first battery pack and the second battery pack, and to alter a second signal received by the electronic processor from at least one selected from the group consisting of the first battery pack and the second battery pack.

An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.

A motorized drapery system having an elongated rotating drive element that has a non-circular cross-sectional shape such as square, rectangular, trapezoidal, cross shaped or any other non-circular shape that is twisted. In one arrangement the drive element is twisted in one direction along its entire length. In another arrangement the drive element is twisted in one direction in a first section and twisted in an opposite direction in a second section thereby providing a center opening/center closing drapery. A plurality of rings are positioned around the drive element including at least one driver ring that includes a feature that connects to the drive element and is configured to facilitate movement along the drive element, and a plurality of idler rings that are configured to slide along the drive element. A curtain is connected to the rings and opens and closes as the rings move along the drive element.

Described herein are a system and methods for implementing a tool-agnostic device. In examples, the system may determine location and state information using sensors of the tool-agnostic device. Based on this information, the system may communicate with a virtual reality system for display and user interaction with a virtual reality environment. The tool-agnostic device may be removed and re-attached to a number of different tools. The tool-agnostic device allows tracking of a number of different tools without customization or retrofitting each tool. The tool-agnostic device may serve as a safety-shutoff device in addition to tracking tool use and movement. When the system determines that a tool is operating in an unsafe manner the tool-agnostic device may interrupt the power to the tool.
