1. Method of converting a serial data stream into a parallel data stream in a communications interface, wherein the serial data stream is demultiplexed to a given number of lanes and a sync header is prepended to at least one data block of at least one lane, characterized in that for at least one lane a sync word containing one or more bits, excluding the word 01 as static sync header, is given or generated and at least a part of the sync word is used as sync header, which is prepended to the at least one data block.
2. Method according to claim 1, wherein the sync word is spread over one or more sync headers.
3. Method according to claim 1, wherein the sync header contains several sync header blocks, each block containing a given number of bits of the sync word or each block containing the sync word.
4. Method according to claim 1, wherein the sync word is a pseudorandom bit sequence.
5. Method according to claim 1, wherein the same sync word is used in all the lanes.
6. Method according to claim 1, wherein a different sync word is given or generated for at least two lanes, in particular for each lane.
7. Method according to claim 1, wherein the same sync header is used for each data block of a specific lane.
8. Method according to claim 1, wherein at least for two data blocks of a lane following one another different sync headers are used.
9. Interface, in particular SERDES source interface, comprising a gearbox for deserializing a serial data stream and several data lanes comprising means for prepending a sync header to the data blocks, wherein a sync word generator is provided, generating a sync word for at least one lane, wherein means for deriving the sync headers from the sync word are also provided.
10. Interface according to claim 9, wherein the sync word generator is a pseudorandom bit sequence generator.
11. Interface according to claim 9, wherein a sync word generator is provided for each lane.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An injection device for delivering a therapeutic agent to a patient, the injection device comprising:
a body having a patient face and a port face opposite the patient face, the port face having an introducer port including an introducer channel and an injection port including an injection channel, the introducer channel being in fluid communication with the injection channel, the injection channel defining an injection axis;
a delivery tube for subcutaneous delivery of the therapeutic agent to the patient, the delivery tube projecting from and being generally perpendicular to the patient face, the delivery tube defining an introducer axis and being in fluid communication with the injection port;
a patch attached to the patient face and operable to adhesively attach to the patient; and
an injection adapter assembly removably connected to the injection port, the injection adapter assembly receiving a needleless pen injector;
wherein the body has a first body portion including the port face and a second body portion including the patient face, the first body portion and the second body portion being rotatably connected with a flange, the first body portion and the second body portion being independently rotatable about the introducer axis.
2. The injection device of claim 1 wherein the body and the needleless pen injector have complementary threads operable to secure the needleless pen injector to the body.
3. The injection device of claim 1 wherein the injection adapter assembly includes a recess to receive the needleless pen injector, the recess and the needleless pen injector having complementary threads operable to secure the needleless pen injector within the recess.
4. The injection device of claim 1 wherein the injection adapter assembly includes a recess to receive the needleless pen injector, the recess including an adapter needle operable to access the therapeutic agent contained within the needleless pen injector.
5. The injection device of claim 4 wherein the needleless pen injector has an end with a foil across the end, the foil being pierceable by the adapter needle.
6. The injection device of claim 4 wherein the needleless pen injector has an end with a pen port disposed in the end, the pen port being openable by the adapter needle.
7. The injection device of claim 1 further comprising a pop-up indicator disposed in the introducer channel, the pop-up indicator having a normal state when pressure in the introducer channel is normal and an alarm state when pressure in the introducer channel exceeds a predetermined value.
8. The injection device of claim 7 wherein the pop-up indicator includes a self-closing port operable to receive a needle of a needle hub assembly.
9. The injection device of claim 7 wherein the pop-up indicator has a membrane selected from the group consisting of a folded membrane, an accordion membrane, and a deformable membrane.
