A battery powered circular saw includes a rechargeable battery removably attached to the housing and an adjustable shoe pivotally attached to the housing for controlling a depth of cut. A locking mechanism for preventing relative movement between the adjustable shoe and the housing includes a clamp that is located so as to permit the battery pack to be inserted to and removed from a rear end of the housing in a direction that is generally parallel to a plane in which the circular saw blade is disposed.

A Very Local Area Network (VLAN) comprises a power strip device having an electrical connector for connection to an AC power supply line and one or more surge protectors and line filters. Multiple electrical power outlet sockets receive plugs from electrical appliances. A communications pathway interconnects the multiple electrical power outlet sockets to enable communication between appliances connected to the sockets. Electronics configure appliances as they are connected to the sockets to enable them to communicate over the communications pathway.

A battery powered circular saw includes a rechargeable battery removably attached to the housing and an adjustable shoe pivotally attached to a guard assembly for controlling a depth of cut. A locking mechanism for preventing relative movement between the adjustable shoe and the housing includes a depth of cut strap disposed adjacent a first sidewall of the housing. A lever is disposed adjacent a second sidewall of the housing. A tightening element interconnects the depth of cut strap and the lever. The battery powered circular saw additionally includes a handle extending from the housing. The handle is disposed substantially parallel to a direction of cut and oriented horizontally above the housing. The rechargeable battery pack includes a pair of laterally spaced apart guide rails which cooperate with the pair of longitudinally extending grooves to permit sliding movement of the rechargeable battery pack in a direction parallel to the direction of cut.

Techniques for employing a printing infrastructure to access a presentation device. A presentation system according to the present teachings includes a presentation device with a display and a mechanism for rendering an image on the display in response to a print file. A client system according to the present teachings provides the print file to the presentation device using an existing printing infrastructure, thereby obviating the need for a base computer or specialized client system software.
摘要:
A combined on/off and reversing switch, particularly for an electric screwdriver having a reversible motor, has a switch plate which can be rotatably mounted on an end of the motor. Terminals of the motor extend through the switch plate and are selectively contacted by ends of two resiliently flexible contact strips carried by the switch plate. An actuating member is moved along a selected path to rotate the switch plate to select "forward" and "reverse", and then depressed inwardly to flex an end of the appropriate contact strip to complete energization of the motor. The contact strips resiliently bias the actuating member outwardly to switch the motor "off" when the actuating member is released. Switching the motor "on" from a neutral "off" position of the switch involves a two part movement of the actuating member. The switch is of simple and compact construction.

Systems and methods for securing a document for transmission are discussed. In one embodiment, a document is checked for an indication of confidentiality. The document is then passed to a secure driver, in response to a finding of the indication of confidentiality. The document is passed to a non-secure driver, in response to a failure to find the indication of confidentiality. The document is then transmitted after processing by the secure driver or the non-secure driver.
