A battery pack for powering a cordless power tool. The battery pack includes at least one battery cell operable to supply a discharge current, a switch operable to control the discharge current and a protection device to protect the switch. The protection device is positioned such that the device absorbs a current traveling in a direction opposite to that of the discharge current supplied from the battery cell.

A battery pack including an electric coupling assembly. The battery pack includes a top housing, a bottom housing, a cell pad, a plurality of battery cells, a harness, and a circuit board. The harness includes a frame and electric coupler assembly having a plurality of internal and external electric couplings. The internal and external electric couplings include cell couplings and circuit board couplings. The internal and external couplings are held in place during manufacturing by links which are cut after the electric coupler assembly is molded into the frame.

A cutting tool includes a cutting body and a connecting structure configured to support the cutting body. The cutting body can include teeth positioned circumferentially around and extending outwardly from the cutting body. The connecting structure can include a drive shaft for drivingly connecting the cutting tool to a power tool. The connecting structure can also include a connecting plate and a locking member for securing the cutting body to the connecting structure. In some embodiments, the locking member is movable relative to the drive shaft between a locked position, in which the locking member secures the cutting body to the connecting structure, and an unlocked position, in which the cutting body is removable from the connecting structure.

In one aspect, the present invention provides an imager, preferably portable, that includes a source of electromagnetic radiation capable of generating radiation with one or more frequencies in a range of about 1 GHz to about 2000 GHz. An optical system that is optically coupled to the source focuses radiation received therefrom onto an object plane, and directs at least a portion of the focused radiation propagating back from the object plane onto an image plane. The imager further includes a scan mechanism coupled to the optical system for controlling thereof so as to move the focused radiation over the object plane. A detector optically coupled to the lens at the image plane detects at least a portion of the radiation propagating back from a plurality of scanned locations in the object plane, thereby generating a detection signal. A processor that is in communication with the detector generates an image of at least a portion of the object plane based on the detection signal.
