Abstract: A manually operated hammer drill (1) includes a spindle (3) that drives a chuck (5) in a rotary manner about an axis of rotation (6) in a drilling mode, and includes a pneumatic hammer mechanism (4), that hammers against a tool inserted in the chuck (5) in a hammer mode. The hammer mechanism (4) has a piston (10) which performs reciprocating movements (12) parallel to the axis of rotation (6) in a cylinder (11) conformed inside the spindle (3) when hammer mode is activated. The piston (10) has at least one radial groove (21) in which an annular seal (22) is arranged.

Abstract: A hand-held hammer drill has a housing, a tool spindle rotatingly driving a tool, a hammer action percussion-driving the tool, a swash plate drive driving the hammer action, and a countershaft driving as needed the tool spindle and the hammer action. A first bearing and an axial bearing are provided. The hub is rotatably supported in a cantilevered arrangement by the first bearing in the housing and coaxially surrounds the countershaft. The hub has a free cantilevered end and the axial bearing is disposed on the free cantilevered end, wherein the axial bearing axially supports the countershaft and has radial play relative to the countershaft.

Abstract: An analyte testing device is provided for use with a mobile processing device having a camera with a lens, a processor for processing an image captured by the lens. The analyte testing device comprises a casing and a test strip positioner. The test strip positioner positions an analyte containing test strip adjacent to the camera lens to permit the camera to capture an image of the analyte containing test strip. A light source is disposed within the casing. The light source is positioned within the casing to illuminate the analyte containing test strip to facilitate the capture of the image of the test strip. Software is contained within the mobile processing device for performing a quantitative analysis of at least one analyte from the captured image, and providing an output of the results of the quantitative analysis.

Abstract: A meter and test wand system is capable of cooperatively processing an analysis fluid and communicating results to a user. The system includes a meter case including a case front, a case back, a case top, a case bottom, a first case side member, and a second case side member. The first and second case side members connect the case front to case back. The first case side member has a longitudinal dimension between said case top and said case bottom and a latitudinal dimension between said case front and said case back. The first case side member includes a first case ridge; A test wand is capable of receiving an analysis fluid, and includes a cartridge including a cartridge ridge. The cartridge ridge is sized and shaped to matingly engage with said first case ridge to connect said test wand to said meter case.

Abstract: A body fluid testing device includes a body member and a tissue penetrator carried by the body member. A test strip holder is carried by the body member, and a test strip is carried by the test strip holder. The test strip is capable of receiving a body fluid thereon and processing the body fluid into a form suitable for yielding test results relating to the content of the body fluid. The body member, tissue penetrator, test strip holder and test strip are designed for a single use and for disposal as a unit without disassembly.
