Title: Method and apparatus for automatically adapting the amount of warping in a system transmitting information through a non-linear channel
Inventor: BETTS WILLIAM LEWIS
IPC: H04M11/06
Filed: 1994-10-22
Granted: 1995-05-01
Abstract: The present invention discloses an improvement over existing techniques for transmitting data over voice-band telephone channels by automatically adapting the amount of warping or compression that is applied to a sequence of signal points. A sequence of warped signal points, each of which is related to a respective signal point of a predetermined base constellation according to a warp function, is received in a decoder via a transmission channel having a non-linear component. After each of the received signal points is unwarped using substantially an inverse of the warp function, the average dispersions of the received inner and outer signal points about corresponding sequences of expected signal points are calculated. The difference between the average dispersion of the inner and outer points is then computed and used to update the amount of warping or compression in order to further minimize the effects of the channel non-linearity. The desired amount of warping is communicated to the transmitting encoder.

Title: Medicament delivery device
Inventor: GROSS JOSEPH
IPC: A61M37/00
Filed: 1996-10-04
Granted: 2000-01-21
Abstract: A medicament delivery device has a reservoir within a housing and means for driving medicament from the reservoir. The device is provided with a filling mechanism upon which a medicament container sealed by a penetrable stopper is mounted. The mechanism comprises an internal bore which accommodate an internal rod from which needle projects. Needle is hollow and is in communication with the reservoir. In order to fill the reservoir, the container is pressed into the bore, causing the needle to pierce the stopper, the stopper abutting against the rod and acting as a piston to drive medicament from the container as the container is pushed into the bore and moves relative to the stopper. Thus, the reservoir can be filled with the sterile medicament which is stable when stored in the container, and the filling is easily accomplished without the use of a syringe. A further advantageous feature is provided by a delivery needle which is mounted on the periphery of the lower surface of the housing. This configuration allows the driving means to be located adjacent to the skin, thereby, providing a more stable temperature and more predictable operation of the device.
