Abstract: A real time contextual information system is provided. In at least one example, the system may include at least one signal scanner that passively scans and detects wireless signals within a region, the wireless signals emitted from communication devices and a central processing unit (CPU) in communication with the at least one signal scanner via network connectivity. The CPU may comprise instructions stored in non-transitory memory that are executable by the CPU to receive information transmitted from the at least one signal scanner, the information based on the detected wireless signals, estimate an amount of human traffic and machine traffic at the region based on the information, and display the estimation.

Abstract: A saw attachment is disclosed having an elongated flexible housing with a first end and a second end, a flexible operating shaft disposed within the elongated flexible housing and having a first end and a second end, a power source removably attached to the elongated flexible housing second end, the power source having a shaft operably connected to the flexible operating shaft second end, a gear mechanism having an input end and an output end operably disposed within the elongated flexible housing first end, the flexible operating shaft first end is operably attached to the gear mechanism input end, a circular saw blade operably attached to the gear mechanism output end, wherein, the hacksaw blade remains rotatable by the power source means through the flexible operating shaft and the gear mechanism when the elongated flexible housing is bent at a desired angle.

Abstract: An electric powered rotary saw for cutting medical cast or the like includes a cylindrical housing, a removable longitudinally extending mounting member and a rotary circular saw blade disposed at one end of the mounting member. The saw blade is fixed to a shaft for rotation about an axis which is generally perpendicular to the longitudinal axis of the mounting member, but slightly offset therefrom. A variable speed electric motor is disposed in the housing and includes a shaft which extends forwardly in a direction parallel with a mounting portion of the longitudinal member. A frusto-conical driver member of an elastomeric material is fixed to the end of the shaft and engages the circular blade to displace a portion of the blade out of its normal plane of rotation by an angle of about 5 degrees and for rotating a circular blade.
