Abstract: Apparatus for casting plugs onto optical fiber ends comprising a mold having a vee-shaped groove for receiving an optical fiber (10) end in butted relationship with either another fiber end or with a mold wall surface (28) which is perpendicular to the vee-shaped groove. Field forces are generated which urge unattached and disposable fiber seating elements (60) into the groove, the seating elements in turn pushing the optical fiber end(s) into the groove until the side surface of the optical fiber end(s) are in tangential contact with both sides (22, 24) of the vee-shaped groove. While the optical fiber end(s) are so positioned, casting liquid is introduced into the vee-shaped groove. The seating elements remain within the casting.

Abstract: An optical assembly structure wherein miniature optical components such as lasers, modulators, lenses, thin-film and fiber-optic waveguides, and photodetectors are critically aligned and supported for coactive operation by means of two or more wafers which are formed with complementary grooves and mortises to support the loose optical components such as lenses and fiber-optic waveguides and to receive alignment rails to insure the relativity of the wafers, which also have formed integral therewith optical elements such as waveguides, modulators, and lasers, to produce an integrated optical assembly somewhat in the manner of an "optical bench," wherein the bench structure also provides an active optical element.

Abstract: A user interface includes a process model unit (34) for predicting one or more allowable next states, from a current state of a process, and a display processing unit (26) for deriving, for each of the allowable next states, a representation of the allowable next state. The display processing unit has an output coupled to a display screen (30) for displaying each of the representations (30b-30g) in conjunction with a representation (30a) of a current state of the process. The user interface further includes an actuator control unit (22) that is coupled to an input mechanism whereby a user selects one of the displayed representations of one of the allowable next states. The motor control unit controls the process to cause it to enter a new current state that corresponds to the selected derived representation. In one embodiment, the display screen has a touchscreen capability whereby the user selects one of the representations by physically touching the display screen within an area associated with a selected one of the derived allowable states.

Abstract: @ A copy-protection scheme is implemented for software which may be stored on a magnetic storage medium such as a disk. The medium (62) is comprised of sections which are divided into subsections, with an original having indicia on at least one subsection of at least one section that is not modifiable by the medium write process, with a copy having no such indicia, or having indicia in a different pattern. A product program may be stored on the medium, and is executable only if the particular medium is an original. A medium test program (80, 82) may also be stored on the particular medium, and is used to test if the medium is an original or a copy. The test program writes the sections with a test pattern which generates a change in the pattern of magnetic domains of the medium, a subsection at a time, with a subsection responding to the test pattern only in the absence of indicia thereon, to form a stored pattern on the given section. An expected pattern (94) and the stored pattern (72) are compared at least a subsection at a time to determine if corresponding subsections have a predetermined pattern of magnetic domains. The product program is executed only in response to the comparison (97) determining that corresponding subsections have predetermined patterns of magnetic domains which is indicative of the presence of said indicia, and the particular medium being an original.
