An evacuation system is provided for removing smoke generated during a surgical procedure performed in a surgical room. The evacuation system includes a pre-filter assembly and a replaceable filter cartridge module disposed in the surgical room to permit replacement of used filter cartridge modules with new filter cartridge modules by personnel within the surgical room. A vacuum generator is disposed outside of the surgical room and includes a vacuum pump for establishing an air flow through the replaceable filter cartridge module. The pre-filter assembly includes an elongate flexible suction hose that is adapted for manipulation into position adjacent the medical procedure. A mechanical connection mechanism enables pre-filter assemblies to be easily replaced between each surgical procedure. An accumulated filter usage circuit calculates a quantity of filter capacity available and generates a filter loading signal based on the available capacity. The filter usage is calculated by adjusting usage counter in proportion to the speed of a vacuum motor and pump mechanism.

A growth factor delivery system for use in connection with microdermabrasion includes a source of growth factors. The growth material may be dry and thus mixed in with the abrasion media. The dry growth material would therefore be applied to the target skin area simultaneously with the abrasion media by a single handpiece. The growth material may comprise a fluid to be delivered by a separate handpiece. The fluid source may be within the handpiece or external thereto. The fluid source may be contained in a removable cartridge adapted to fit within the handpiece. Thus, a method and system is provided for using disposable cartridges of growth fluids.

A digital scale includes a display screen and a buttonless top platform. A controller is operatively associated with the display screen and the platform. Contact with the scale platform alone allows a user of the scale to power the scale, determine a mode of operation of the scale, and identify a user of the scale. Additionally the scale has a first mode of operation providing a reading of the user's weight and a second mode of operation providing an attribute that is dependent upon a weight of an identified user.

A method and apparatus is disclosed herein for determining the location of a device with the assistance of fixed receivers. In one embodiment, the method comprises receiving a first request from the mobile device in the wireless network; wirelessly transmitting one or more positioning requests in response to the first request; receiving signal strength information from one or more receivers in the wireless network sent in response to the one or more positioning requests; determining a location of the mobile device based on received signal strength information by comparing the received signal strength information with signal strength information of reference locations; and sending location information to the mobile device, where the location information is indicative of the location of the mobile device.
