Abstract: An improved detector device for locating studs and other objects behind a substrate (such as a wall) uses one or more light emitting diodes (LEDs) in combination with a photochromic compound to mark the locations on the substrate behind which objects are located.

Abstract: A desktop laser cutter configured to cut a cylindrical workpiece includes a laser, a cutting head that receives an electromagnetic beam from the laser and emits a cutting beam, and a gantry that supports the cutting head relative to a base plate of the laser cutter housing. The gantry can be actuated to move the cutting head within a plane that is parallel to the baseplate. The cutting head emits the cutting beam in a direction parallel to the plane. In use, the cutting head is disposed side-by-side with the workpiece and the cutting beam is applied to a side of the workpiece that faces a sidewall of the laser cutter housing. The workpiece is supported by the gantry to rotate an amount that is a function of movement of the cutting head in a direction parallel to the plane.

Abstract: A hand-held rotary tool includes a housing that encloses a motor having an output shaft. The tool includes a quick connect adaptor configured to connect an accessory to the output shaft. The adaptor includes a driver that is connected to the output shaft and rotates in concert with the output shaft. An outer surface of the driver has a first flat. The adaptor includes a receiver that includes a connector configured to detachably connect with the housing, and a torque transfer device configured to receive the driver. An inner surface of the torque transfer device includes a second flat that engages with the first flat in such a way that rotation of the driver results in rotation the torque transfer device relative to the connector. The adaptor includes an output device that supports the accessory and that is driven by the torque transfer device to move relative to the connector.

Abstract: A smart power hub having a number of electrical connections for power electric power tools. The smart power hub comprises a controller, a processor, and a number of sensors operable to measure operational behavior of the electrical connections or connected electric power tools. The processor may utilize data from the sensors to generate control commands for the controller to control the current output of the number of electrical connections. Additional functions of the processor may provide smart feature operation to connected tools.

Abstract: A hand-held rotary cleaning tool includes a housing that encloses an electric motor and a gear set that connects the motor to an output shaft. The rotary cleaning tool includes at least one cleaning accessory that is detachably connected to the output shaft, and a flexible splash guard. The splash guard surrounds the output shaft and cleaning accessory so as to prevent liquid splash during tool use. The splash guard includes a reinforcing ring that is formed of a material that is less flexible than the material used to form the splash guard body. The reinforcing ring prevents the splash guard from excessive deformation, whereby interference of the splash guard with the cleaning accessory or the output shaft is minimized or avoided. The reinforcing ring may also include other features which enhance the cleaning function of the rotary cleaning tool.

Abstract: By providing a unique housing member within which a plurality of separate display and holding members are operatively interconnected for sequential display relative to each other in a unique, cooperative, continuous, extending manner, a unique, hands-on, visually exciting and interest generating multi-panel display and holding system is realized. In the preferred construction of the present invention, a plurality of separate and independent display and/or holding members are cooperatively interconnected to each other for sequential movement relative to each other. Furthermore, each of the display/holding members are also constructed for being automatically positioned in a precisely desired continuous array in response to the receipt of pulling or movement force applied to one of the display/holding members or to a designated lead element.

Abstract: By providing a housing member within which all of the required elements are pre-formed and constructed as a display system which enables any desired graphics to be inserted therein to form an integral part of the assembly, a unique, printed, visually exciting and interest generating foldable, three-dimensional display system is attained. In accordance with the present invention, the interest generating, foldable display system of the present invention is quickly and easily automatically erected from its flat, generally two-dimensional configuration into a three-dimensional display. Furthermore, the housing preferably comprises an enlarged internal cavity for receiving any desired display element. In this way, the display assembly is easily, and automatically converted from a two-dimensional, substantially flat configuration into a three-dimensional fully erected, interest generating, visually exciting display.

Abstract: Method and apparatus for fault management of computer networks which utilizes a proxy or recruit network device to test the responsiveness of a network device. When a first network device loses contact with a second network device, the first network device uses a proxy network device to determine if the second network device can be reached and reports back to the first network device whether the contact attempt was successful. The proxy network device may contact the second network device through a different path and/or protocol than used by the first network device.

Abstract: A system determines that a frame relay connection exists between an interface on a first interface device and an interface on a second interface device, for example by comparing addresses resident in routing tables of the interface devices. The system then queries each of the first and second interface devices, to determine the amount of traffic that is communicated by each channel of each of the two interfaces. This data is then correlated to determine the relative amount of data by each channel on each of the two interfaces, and the pair of channels having the best correlation are determined to represent an actual connection.
