Abstract: A method of and apparatus for treating tissue wherein a handpiece with a cartridge of motor driven needles is placed in contact with tissue. The motor is energized to drive the needles. Energy is applied energy to the needles. Tissue impedance at the start of treatment is measured. Tissue impedance at the end of treatment is measured. The operator is then notified that corrective action is needed if the measured ending impedance is higher than the measured starting impedance indicating the needles are not inserted into the tissue.

Abstract: A treatment apparatus includes a motorized subsystem in a handpiece housing having a rotating output shaft, an axial cam driven in rotation by the output shaft, and a push rod linearly driven by the axial cam. A cartridge is removably attachable to the handpiece housing and includes a cartridge housing, a needle assembly, a piston in the housing engaging the needle assembly and linearly driven forward by the push rod, and a first biasing member urging the piston rearward.

Abstract: A printer assembly (10) adapted for use with a print head comprising a platen (14) operable to move in a first plane; and a vacuum source in fluid communication with the platen (14) to provide a vacuum communication path to draw air through the platen (14) such that a sheet of media arranged on the platen (14) is biased towards it, characterised by a movable aperture (52) in the vacuum communication path between the vacuum source and the platen (14), the movable aperture (52) being arranged to move with the platen (14).

Abstract: A device (1) for monitoring a vital sign of a living subject, comprising a measuring unit (2) for measuring at least one physical quantity indicative of said vital sign at an area (8) overlying an artery (7) of the subject, which measuring unit (2) is provided on a carrier (3) to be worn by the subject during operation, and a processing unit (4) for processing the measured physical quantity into a value for the vital sign, which device (1) is provided with at least one detector (5) for detecting the position of the measuring unit (2) relative to the artery (7) of the subject during operation and for actuating a feedback signal (Ufeedback) in dependence on this position. The user can move the device (1) relative to the artery (7) until the feedback signal (Ufeedback) is given, and thus a correct positioning of the measuring unit (2) relative to the artery (7) is achieved in an easy manner.
