An anal retractor includes four retractor valves (48), which are offset 90° relative to each other and can be moved radially apart from each other. For this the four retractor valves (48) are guided by sleds (30) in radial guide slots (14) of a base plate (10). For movement of the sleds (30) guide bolts (36) extend through the radial guide slots (14) of the base plate (10) and spiral shaped actuating slots (24) of a rotor plate (20), which is rotatable relative to the base plate (10).

A vacuum cleaner attachment and method of use thereof provides an effective cleaning system for fungi and the like. A vacuum paddle extension enables the attachment to travel into narrow cracks and crevices where fungus may grow and by use of an abrasive and porous pad dislodges such fungus or fungi. When attached to a vacuum system, such as a HEPA (High Efficiency Particulate Air-Filtered) vacuum system, the debris and particulate matter generated by the abrasive process is drawn into the vacuum attachment and into the vacuum system where it is removed from the air which is then expelled by the vacuum system. Better cleaning of surfaces afflicted with fungi, molds, and the like is then achieved in a manner that is safer and more effective.

A specific cavity extractor extracts an isolated group corresponding to a left ventricle from among a plurality of isolated groups to which numbers are attached in a labeling section. A major axis slope calculator section sets, as a left ventricle major axis, a straight line passing through a center of mass calculated in a center-of-mass detector section and a major-axis end point detected in a major-axis end detector section. A cavity cross sectional area calculator section calculates a cross sectional area of four cavities for each of a plurality of cutting planes including the left ventricle major-axis. An optimum cross section setter sets, as a four-cavity cross section, a cutting plane in which the cross sectional area of the four cavities becomes maximum.

A bumper crossbeam for a motor vehicle includes an outer section configured as a roll-formed hollow profile which is closed at least in some areas. At least one inner section, configured as a separate component, is arranged in the outer section and connected to the outer section. The inner section has at least one wall extending from a front section zone of the outer section to a rear section zone of the outer section.

A stator assembly for use in a superconducting generator operated at frequencies up to 10 Hz is disclosed. The stator assembly includes a ferromagnetic stator winding support having a plurality of teeth defining slots, the slots configured to receive and support stator windings. The stator winding support is formed so that the ratio of the sum of the widths of the slots to the sum of the widths of the teeth and slots is in the range of 0.65 to 0.90.

The present invention relates to a positive photosensitive resin composition and a method for forming a pattern by using the same. The positive photosensitive resin composition includes a novolac resin (A), a polysiloxane (B), an ortho-naphthoquinone diazide sulfonic acid ester (C) and a solvent (D). The novolac resin (A) includes a xylenol-type novolac resin (A-1). The xylenol-type novolac resin (A-1) is synthesized by polycondensing an aldehyde compound with a xylenol compound.

The invention relates to a measuring device which determines the filling level by means of high-frequency measuring signals which are guided along a waveguide. The invention is based on the object of optimizing the waveguide. According to a preferred embodiment of the apparatus according to the invention, the waveguide is a wire cable which comprises a plurality of individual wires of a predetermined diameter which are twisted together.

User interaction with a display is detected substantially simultaneously using at least two cameras whose intersecting FOVs define a three-dimensional hover zone within which user interactions can be imaged. Separately and collectively image data is analyzed to identify a relatively few user landmarks. A substantially unambiguous correspondence is established between the same landmark on each acquired image, and a three-dimensional reconstruction is made in a common coordinate system. Preferably cameras are modeled to have characteristics of pinhole cameras, enabling rectified epipolar geometric analysis to facilitate more rapid disambiguation among potential landmark points. Consequently processing overhead is substantially reduced, as are latency times. Landmark identification and position information is convertible into a command causing the display to respond appropriately to a user gesture. Advantageously size of the hover zone can far exceed size of the display, making the invention usable with smart phones as well as large size entertainment TVs.

The invention relates to a pneumatic gripper which comprises a gripper body (21,121), at least two pneumatic control pistons (23) operating within at least one chamber (22,122) defined by the gripper body and movable in opposite directions with respect to each other by a driving fluid supplied to the chamber, at least two guide columns (34) associated with each piston and emerging from the ends of at least the chamber, and at least two jaws (37) movable with the pistons between an active position for gripping a work-piece and an inactive position for releasing the work-piece. The guide columns (34) are attached directly in front of and inside the profile of a respective piston (23), and each gripping jaw (37) may be attached directly to the ends of the columns of a relevant control piston.

An interferometer type deflection measuring device having a radiation source, a first fiber-optic means forming a first light path, a second fiber-optic means forming a second light path, a deflection body and an evaluation circuit, the first and second fiber-optic means receiving radiation from the radiation source on an input side, and radiation guided in the first and second fiber-optic means, respectively, being brought together on an output side with interference radiation being conveyed to the evaluation circuit for evaluation. The first fiber-optic means and the second fiber-optic means are arranged only on the deflection body, at least one of the first and second fiber-optic means being connected on the input side to the beam source with a single feed optical fiber and at least one of the first and second fiber-optic means being connected on the output side to the evaluation circuit by a single evaluation optical fiber.
