Abstract: An optical module is packaged using one or more internal fiber connections which are arranged to minimize the likelihood of internal connection damage when the module is installed on a circuit board. The module includes at least one external connector arranged on a side of the package, and a submount within the package for supporting a component such as an optical source or an optical detector. An optical fiber is connected within the package from the submount to a connector interface of the external connector. The end of the fiber at the connector interface has a preformed connector thereon which engages a ferrule associated with the interface. The other end of the fiber is attached to the submount for optimal coupling efficiency. The fiber may undergo a bend of about 90.degree. or 180.degree. from its first end to its second end. In order to accommodate the fiber bend, the component submount is positioned within the package in a location remote from the external connector.

Abstract: A breakaway coupling device is provided having a male and female valve body. The female valve body, a plurality of boltholes extending therethrough, and a plurality of boreholes extending therethrough. The female valve body further defines a first cavity traversing the female valve body. The male valve body has a plurality of flange pairs and a plurality of boreholes aligned with the boreholes in the female valve body. There are a plurality of tie bolts attached to the female valve body through the plurality of boltholes. The tie bolts are received by the plurality of flange pairs on the male valve body. There are a plurality of shear pins. Each one of the plurality of shear pins intersects each flange pair and each one of the plurality of tie bolts at an angle perpendicular to the tie bolts thereby connecting the male valve body to the female valve body. There are plurality of guide pins closely received by the boreholes in the male valve body and the female valve body.

Abstract: The coupling of the present invention is adapted for use with a micromanipulator and a pair of pipettes. The micromanipulator comprises a pair of elongated arms and linkage connected to the arms for moving the arms in a plurality of directions. The coupling includes a housing having an arm receptacle at one end and a pipette holding device at the opposite end. A ball and socket swivel is provided within the housing and comprises a movable socket member which is matingly engaged with a spherical ball. The ball is connected to the pipette holding device. A threaded bolt engages the movable socket member and is adapted to cam the socket member into frictional engagement with the ball so as to lock the ball and socket joint against movement.
