Abstract: The disposable trochar in the form of a gas insufflation needle (N) having a removable rod (16) and needle (10) portion within an outer sheath (30) is provided. The rod (16) has a blunt end (20) and is retractable during insertion so that the needle edge (12) cuts through the abdominal wall (64, 67, 68). Once passing through the wall (64, 67, 68) the rod (16) extends so as to protect the bowel (72) from the sharp needle (10). A gas port (56) is provided for introducing gas through the rod (16) and out a side passageway (22) near the blunt end (20). After the abdomen is extended, the rod (16) and needle (10) can be removed as unit from the sheath (30) and thrown away and a suitable instrument (74) introduced through an instrument port (60) having a separable diaphragm (62). The gas can continue to be introduced around the instrument (74) and into the abdomen while the instrument (74) is in place. After the required medical procedures are completed, the instrument (74) is removed. Then the sheath (30) and associated parts are removed and thrown away.

Abstract: In a development portion (2) of a directed graph, when a program specification (1) is provided, descriptive elements having characteristics of sets described in the specification and descriptive elements defining a calculation method described therein are mapped with vertices and arcs based on descriptive elements defining a calculation method described therein are drawn between the vertices. Thus, the program specification is developed to the directed graph. The developed directed graph is analyzed by an analyzing portion (3) in view of the characteristics of sets and mappings and global characteristics of the directed graph, and arcs and vertices where flows of execution timing of the calculation synchronize and arcs and vertices where flows of execution timing of the calculation do not synchronize are detected. A program structure defining portion (4) handles the arcs and vertices where the flows of timing synchronize and the arcs and vertices where the flows do not synchronize, by different methods, thereby determining a data structure and a procedure structure as the program structure.

Abstract: Operating functions, on the basis of which a switching device can be set as required, but which are to some extent mutually exclusive, are assigned individually to the function keys in an input keyboard. Input information is fed to an evaluation logic circuit which, when a combination of mutually exclusive functions is entered, converts this combination into an alternative combination of functions. An alternative combination is selected of the type which, in comparison with the originally entered combination, has the minimum number of function changes. The functions are displayed according to the alternative combination by means of a display device. <IMAGE>

Abstract: The connector latch is intended to assist the mating of an electrical connector assembly (10) (see Fig. 1) comprising a socket connector (12) and a plug connector (14). The latch comprises a pair of latch arms (130, 131) on one connector (14) in a mateable pair each of which is resiliently deflectable about a first axis (Y1, Y2) and which is disposed to contact a cam (54) on the opposed connector (14) during mating. The deflectable latch (130, 131) and/or the cam (54) define leading ramp surfaces (56, 57, 36, 37), trailing ramp surfaces (58, 59) and locking surfaces (38, 39). The leading ramp surfaces (56, 57, 36) 37) are disposed to resiliently deflect the latch arms (130, 131) and develop stored energy therein. The trailing ramp surfaces (58, 59) employ the stored energy developed in the latch arms (130, 131) to urge the connectors (12, 14) toward a fully mated condition. The latch arms (130, 131) include spring steel wire inserts (134) for reinforcement, such that the plastics latch arms (130, 131) do not become permanently deformed. The connectors (12, 14) may be disengaged from one another by biasing the latch arms (130, 131) about a second axis (X) away from the associated connector (12, 14) a sufficient amount to clear the cam (54) and enable disengagement of the connectors (12, 14).

Abstract: An automatic focusing device employs an active range finder (11) to establish an initial range to an object (16). A blur is calculated based on the initial range. If the blur is less than a predetermined value, the active range finder (11) is bypassed in favor of a passive range finder (12). A focusing drive (31) is responsive to the output of the passive range finder (12) to drive the focus toward zero blur. If the initial range provides a blur calculation exceeding the predetermined value, the focusing drive (31) responds to the active range finder (11) until the calculated blur is reduced to a second predetermined value, at which time the active range finder (11) is bypassed in favor of the passive range finder (12). Thereafter, the focusing drive (31) responds to the passive range finder (12).

Abstract: A scanner (A), such as a computed tomography (CT) or magnetic resonance (MR) scanner, non-invasively examines a region of interest of a subject and generates a plurality of views which are reconstructible into an image representation. A filter control (14) generates a bandwidth scaling factor (BWF ϑ ) and a bandwidth offset (BWO) for each view. Preferably, the selected bandwidth scaling factor is the maximum of a plurality of bandwidth scaling factors based on different criteria including noise, missing views, material surrounding the region of interest, and noise texture. The bandwidth scaling factor is then used to address a filter curve look up table (18) to select a plurality (N T ) of filter values. The digital filter values are interpolated (20) or extrapolated as necessary to match the number of values (N S ) in each sampled view. The digital filter values and the view values are multiplied (22) point by point to create filtered views which are reconstructed (30) into the image representation for storage in an image memory (32) or display on a video monitor (34).

Abstract: An essentially symmetrical ratio decoder which covers all areas in both the positive and negative regions with only a small number of noted exceptions. Multiple boundaries were selected such that the positive and negative regions were symmetrical with only a small number of exceptions. Using these boundaries, an essentially symmetrical, unified ratio decoder was constructed using only about one-half of the integrated circuit real estate of conventional ratio decoder pairs. By decoding the sign bit from the ratio decoder adder, the ratio decoder recognizes the exceptional areas and handles them accordingly.

Abstract: A mixture is prepared by mixing carriers to which a substance specifically reacting on an object substance adheres with a sample containing the object substance. The mixture is irradiated by light having an intensity gradient to concentrate the carriers at and near the irradiated positions by the optical pressure of the light. The efficiency of an agglomeration reaction e.g. antigen-antibody reaction of the carriers is thereby increased. A qualitative or quantitative measurement of the object substance is performed by detecting optically a state of agglomeration of the carriers within the mixture.
