Title: Polyvalent carbohydrate molecules
Inventor: LUPESCU NICULINA
IPC: A61P31/04
Filed: 1998-03-10
Abstract: Methods for syntheses of polyvalent carbohydrate molecules by glycosylations of partially protected polysaccharides with a single glycosylating agent or a mixture of glycosylating agents (i.e., a combinatorial library) are disclosed. An alternate method utilizes a glycoside, the aglycon of which carries a halogen which can be under strong alkaline conditions linked with a partially protected polysaccharide by an ether linkage. The product of the latter reaction can be subjected to further glycosylation with a single glycosylating agent or a mixture of such agents (=library). The novel resulting polyvalent carbohydrate molecules may be used as antiinfective agents (antibacterial, antiparasital), both for prevention and treatment of diseases, and as agents either for preventing the formation of, or disrupting, biofilms.

Title: Integrated beam shaper and use thereof
Inventor: TEKOLSTE ROBERT
IPC: G11B7/135
Filed: 1998-08-21
Abstract: A substrate having an optical element on an input surface thereof receives a light beam not having a desired beam shape and shapes the light beam into a predetermined intensity distribution. The substrate may further include a second optical element for providing a predetermined phase pattern to the light beam provided by the first optical element. The first optical element may, for example, circularize an elliptical light beam using a soft aperture for differential power attenuation or by altering the divergence of the light beam along the different axes of the light beam. When the divergence angles are altered and the collimating optical element is provided on the output surface, the thickness of the transparent substrate is determined in accordance with a resultant difference in the divergence and/or with the initial difference in beam size along each axis and with a required circularity. A light source is mounted close to the first optical element in order to minimize the amount of differing divergence present along the different axes of the light beam. The optical elements may be diffractive, refractive, or hybrids thereof and are preferably prepared photolithographically on the substrate itself. The light source may be mounted using fiducial marks and the photolithographic processes for forming the optical elements may also use fiducial marks. All elements of the integrated beam shaper may be formed on a planar, wafer level.

Title: Practical space-time radio method for cdma communication capacity enhancement
Inventor: SCHERZER SHIMON B
IPC: H04B7/04
Filed: 1998-09-15
Abstract: A practical way to enhance signal quality (carrier to interference, C/I) in both up and downlink of wireless point to multi-point CDMA service implements basic radio direction finding techniques to allow for optimal diversity combining in an antenna array employing large number of elements. This approach is facilitated through the use of very small bit counts arithmetic and capitalizing on finite alphabet signal structure (Walsh symbols, for example in IS-95 CDMA) or a known training sequence. Alternate implementations can use floating point data representations. The method facilitates ASIC implementation, thereby enabling distributed processing to achieve the required computation practicality. The method utilizes the uplink channel data to determine the downlink spatial structure (array beams) to enhance downlink G/I and hence increase downlink capacity. The preferred embodiment is optimized to IS-95, however any signal that has either a finite alphabet or a training sequence built in can utilize the same idea. The use of the known signal structure facilitates simple array response vector determination and eliminates the necessity for covariance matrix calculation and analysis. Hence, this approach can be utilized for GSM and TDMA wireless air-interfaces as well.
