A cutting tool for cutting sheets of materials, such as, for example, sheets of building materials. The cutting tool includes a working table with a support surface. The working table includes a slot extending through the support surface. The cutting tool further includes a handle and blade pivotally engaged with respect to the working table between an open position and a closed position. The cutting tool further includes a guide rail that can be connected to the base in a plurality of positions relative to a cutting plane of the blade include a parallel position and a perpendicular position.

A gauge cutting system and method are described herein. The gauge cutting system includes a cutting apparatus coupled to a track for cutting a wire and a movable measurement apparatus spaced from the cutting apparatus and coupled to the track. The measurement apparatus for measuring a length of wire extending from the cutting apparatus by looping said wire around said measurement apparatus and returning a cut end of the wire to the cutting apparatus, wherein a distance of the measurement apparatus from the cutting apparatus is proportional to the length of wire to be cut.

A shearing tool includes a drive device and a shearing assembly. The drive device includes a housing and an output member linearly movable relative to the housing along a drive axis. The shearing assembly includes a frame coupled to the housing, a blade pivotally coupled to the frame, and a linkage assembly interconnecting the output member and the blade. The blade is pivotable relative to the frame about a pivot axis in response to movement of the output member along the drive axis.

The present invention relates to systems and methods for characterizing at least one anatomical parameter of an upper airway of a patient by analysing spectral properties of an utterance, comprising: a mechanical coupler comprising means for restricting the jaw position of the patient; means for recording an utterance; and processing means for determining at least one anatomical parameter of the upper airway from the recorded utterance and comparing the recorded utterance to a threshold value. In addition the present invention relates to the use of the above mentioned systems as a diagnostics tool for assessing obstructive sleep apnea.

A slit-cutting device includes a first holder, a second holder, a first contactable member a second contactable member, and a protrusion member. The first holder includes a medium faceable area and a first contactable member. The second holder holds a blade and includes a second contactable member. A cutting edge of the blade may cut a medium between the first holder and the blade. The first contactable member and the second contactable member contact each other and defined a closest approach distance between the cutting edge and the first holder. The closest approach distance is longer than zero and below a thickness of the medium. The protrusion member protrudes more than the closest approach distance from a part of the medium faceable area. The cutting edge may make a cut line includes at least a part of a slit-cut and a full-cut in a cutting edge direction in the medium.

A hot wire cutting machine. Hot wire cutting machine comprises a heated wire (101); springs (102 and 102a) and grooved rods (103, 104 and 401) supported on end bearings (402 and 403) and optional bearings (404) at middle of the rod (103, 104 and 401) wherein the rod (401) is coupled to a motor 504 for rotating the rod (401) in the direction of wire movement due to thermal effects and achieve minimum rubbing between wire and rod. The composite cutting wire comprises a first wire (1209) which is thicker, braided, high-strength, low electrical resistance joined with a second wire 1201 which is having high-electrical resistance (NiChrome) wherein the first wire (1209) and second wire (1201) are joined by manual twisting/welding and the first wire (1209) is capable of withstanding bending cycles moving over threaded/grooved rod (1203) and oscillated along its length by to-fro rotation of splined shaft (1204).
