Abstract: An electronic component for providing optical isolation an electronic component package, a phototriac disposed within the electronic component package for providing the optical isolation, and a reverse zero-cross feedback channel integrated into the electronic component package to thereby provide zero-cross detection. The electronic component may be in a circuit which includes a phase control circuit. A method of driving an AC load and providing zero-cross detection using a single electronic component includes providing an electronic component having an electronic component package, a phototriac disposed within the electronic component package, and a reverse zero-cross feedback channel integrated into the electronic component package to thereby provide for zero-cross detection. The method further includes placing the electronic component within a circuit.

Abstract: An injection casting system for encapsulating semiconductor products and method of use includes a mold unit having a cavity, a substrate material placed against the cavity, the cavity being filled by a liquid dispenser in contact with the bottom of the cavity and a running channel at the bottom of the cavity to receive the liquid dispenser for even dispersion of epoxy in the cavity from the bottom of the cavity upward to the top of the cavity.

Abstract: An apparatus and method of making the same for sensing inclination. The apparatus includes a member moveably positioned in a body, the member moves in response to gravity between two positions if the body is rotated relative to an axis exceeding a certain amount. A detector can be used to detect when the member moves and can automatically report rotation. A method of making an inclinometer includes creating the body by laminating layers, where a layer is prefabricated to include an appropriate cut-out to guide the member between the two positions. Another layer or layers can include the detector. An aspect of the invention comprises having each layer include prefabricated features for multiple inclinometers, and then superposing the prefabricated layers, activating adhesive between them to form a lamination defining a plurality of inclinometers, and then separating the lamination into individual inclinometers.

Abstract: An electrically-conductive grid placed between an LED and a photodiode prevents false triggers of the photodiode by transient electrical fields. The grid terminates the field but allows light output of the LED to pass to the photodiode.

Abstract: A spot detector including a light source with a lens arranged in the path of the light from the source and a lens disposed in the path of the light reflected from the medium surface. An opaque mask is provided on the far side of the receiving lens. The opaque mask is configured with at least one slit such that the size and location in two dimensions of a single spot may be detected. A photodetector generates a voltage proportional to the amount of light impinging on its photosensitive surface, which depends upon whether or not a spot is present. According to one embodiment of he present invention, a layered mask is provided wherein the optical working distance to a given mask opening is staggered by placing it on different mask substrate layers. Accordingly, different portions of the depth of field can be resolved.
