Title: Breathing-controlled inhalation device for dry powder and method for the even distribution of said dry powder in the air
Inventor: GOLDEMANN RAUL
IPC: A61M13/00
Filed: 2000-10-06
Abstract: The invention relates to a breathing-controlled inhalation device for dry powder and is characterized by a simple design, small size and low production costs. The inventive device has a double dose protector and ensures complete and even distribution of the dry powder during the inhalation procedure. Also disclosed is a method is disclosed which enables a complete and even respirable distribution of the dry powder to be inhaled in the air. The reservoir is coupled to a dosing conveyor dips into submerged in the transfer area in such a way that a predetermined amount of dry powder can be positioned directly at the beginning of the air guiding unit and flowing air guided by the air guiding unit takes on a three dimensional zigzag-like shape. Air drawn in during inhalation is channeled in such a way that acceleration and subsequent decceleration of the air stream occurs alternately and turbulence of the direction of flow is induced.

Inventor: GUIRAO ANTONIO
IPC: A61B3/028
Filed: 2001-10-04
Abstract: Ocular refraction is determined from wavefront aberration data, and an optimum customized correction is designed. The eye's wave aberration is measured (202) by using a detector such as a Shack-Hartmann detector (714). From the aberration, an image metric is calculated (214), and the second-order aberrations which optimize that metric are determined (218). From that optimization, the refractive correction (220) required for the eye is determined. The image metric is one of several metrics indicating the quality of the image on the retinal plane or a proxy for such a metric. The required refractive correction (220) can be used to form a lens or to control eye surgery. If it is possible to detect more aberrations than can be corrected, those aberrations are corrected which most affect vision, or for which the eye's error tolerance is lowest.

Abstract: A wired and wireless communication method and apparatus for reducing a PAPR  (Peak to Average Power Ratio) in an OFDM (Orthogonal Frequency Division Multiplexing) system. A transmitter of the OFDM system designates, as a coset leader, a vector capable of minimizing a PAPR in a general standard array of (n, k) linear block codes and transmits a sequence having a minimum PAPR by adding each coset leader to an n-bit codeword corresponding to k-bit information and producing U (.iexcl.Â2n-k) number of vectors. Then, a receiver of the OFDM system can easily recover an original transmission signal using a syndrome of a received vector if the receiver identifies information of the syndrome and the coset leader.

Abstract: In a mailing system for franking a postage indicium serving as a proof of postage, postal data including the postage needs to be communicated through such an indicium. Illustratively, the postal data is categorized into (a) invariable postal data, e.g., a device ID identifying the mailing system, which is unaffected by a franking transaction, and (b) variable postal data, e.g., the postage, which may change from one franking transaction to another. To avoid latency of the franking operation, the invariable postal data is preset for initial printing of the postage indicium, and the variable postal data is determined and set for printing in real time. In printing the postage indicium, the invariable postal data and the variable postal data are presented in that order in one or more symbols.
