Title: Optocomponent capsule having an optical interface
Inventor: ENGSTRAND JAN-AKE
IPC: H01L31/0203
Filed: 1995-10-19
Granted: 2005-04-19
Abstract: In encapsulating an optocomponent with a plastics material an MT-connector compatible interface is obtained having bores for guide pins in the wall of the capsule and optical connection surfaces. These bores are obtained from mould cavity guide pins which are used for aligning the optocomponent in a mould cavity in a mould in the moulding operation of the encapsulating material on top of the component. In order to achieve a good accuracy in the positioning of the component during the moulding operation the mould guide pins are as short as possible and end directly behind the component where they are supported by projections extending from each mould half. Thus cavities are created extending straight through the capsule behind the component. The cavities allow that the guide pin bores are cleansed and that material residues are removed after the moulding operation. Further, the cavities can be used for spring clamps which are used for retaining the optocomponent capsule at an optical connector having a similar interface.      The clamps can then have tongues which are inserted in the cavities and which, in addition, can be provided with holes, through which the guide pins can be pushed to safe-guard the clamp against being lost.

Title: Method and system for post-processing differential global positioning system satellite positional data
Inventor: NELSON FREDERICK
IPC: G01S5/00
Filed: 1998-03-09
Granted: 2000-10-24
Abstract: In a DGPS, accurate post-processed corrections to user receiver locations are made while minimizing the amount of data required to be stored at reference station and user receiver positions.  Further, such corrections are available even if reference station corrections cannot be received by the user in real-time.  The user receiver acquires in-view GPS satellites, computes, and stores user stand-alone position, time of computation, and acquired satellite identification.  Reference stations generate correction data for the same satellites at the same time period, which correction data are broadcast but need not be received by the user in real-time.  Almanac information for the relevant satellites is also made available to at least the user receiver.  Stand-alone user receiver positional data and the almanac data for the same acquired satellites are used by a CPU, located at a remote site able to receive reference station transmissions and/or in the user receiver, to compute corrections to user receiver positions.
