Title: Administration of insulin by jet injection
Inventor: PASS FRANKLIN
IPC: A61M5/30
Filed: 2003-02-12
Abstract: The invention relates to a method for minimizing mean blood glucose levels i n an insulin dependent patient by administering insulin to the patient in a sufficiently fast manner to provide a difference of 50% or less between high and low blood glucose levels. Advantageously, the insulin is administered to the patient by jet injection and the high and low blood glucose levels diffe r by an amount that is less than that which would be obtained after injection of insulin by a conventional needle syringe. The invention also relates to a method for reducing mean blood glucose levels in an insulin dependent patien t that is receiving insulin through a conventional syringe and needle arrangement. This method provides for administration of the insulin to the patient by jet injection rather than by the syringe by substituting a jet injector for the syringe.

Title: Method and apparatus for extending band of audio signal using higher harmonic wave generator
Inventor: IWATA KAZUYA
IPC: G10L21/0388
Filed: 2004-05-14
Abstract: A higher harmonic generator generates higher harmonics of an audio signal according to the input audio signal having a predetermined band. Next, a multiplier subjects the higher harmonics of the audio signal generated to amplitude modulation according to the band signal having a predetermined band width, thereby generating an amplitude modulation signal. A digital band pass filter band-pass-filters the amplitude modulation signal generated, by using a predetermined band pass characteristic and outputs it as a band extended signal. Furthermore, an adder adds the amplitude modulation signal which has been subjected to the band pass filtration to the aforementioned input audio signal and outputs an audio signal as an addition result including the band extended signal in the audio signal of the original sound.
