Title: Optical analysis of substances on sensor surfaces
Inventor: FATTINGER CHRISTOF
IPC: G01N21/552
Filed: 1994-03-25
Abstract: Summary The optical process for analyzing substances is based on the measurement of the propagation properties of optical surface waves on sensor surfaces. In a wave guide layer structure in contact with a sample, guided light waves are decoupled with a grating coupler. The decoupling region of the grating coupler is imaged onto a position resolving detector so that the plane of the wave guide layer structure forms the object plane and the detection plane lies in the image plane of the optical imaging. The light distribution of the decoupled wave field in the image plane is measured with the detector and used to determine the analytical quantity to be measured. The device for carrying out the process consists of a suitable wave guide sensor (1,2) with grating coupler (3), an imaging lens system (9) and an optical detector (10).

Abstract: To ensure contact of axially bent-back current supply leads, extending over plate-like base terminals of an elongated fluorescent lamp, and ensure electrical connection between the bent-aver ar bent-beck portions with socket terminal springs (9a, 9b), in spite of misalignment of the bases (3) at two opposite ends of the fluorescent lamp, the junctions or corners (1118) between the narrow wall portions (18a, 18b) and wide side wall portions (11a, 11b; 12a, 12b; 13a, 13b) of the end portion (4) of the base are set back from the position in a theoretical geometric rectangle or parallelogram to form relieved wide side wall portions. The relieved side wall portions extend axially over essentially the entire length of the end portion (4) of the base.

Title: Simultaneous analog and digital communication
Inventor: BREMER GORDON
IPC: H04N21/2368
Filed: 1994-05-26
Abstract: SIMULTANEOUS ANALOG AND DIGITAL COMMUNICATION            Abstract A method and apparatus for concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components. Both half-duplex and full-duplex operation is available in accordance with the disclosure.

Title: Tampon having a protective finger sheath and a method of forming
Inventor: RENTMEESTER TAMMY J
IPC: A61F13/20
Filed: 1994-06-30
Abstract: A catamenial tampon having a protective finger sheath is disclosed along with a method of forming the tampon.  The tampon includes an absorbent pledget having an insertion end and a trailing end.  A cover is secured to the absorbent and at least partially encloses the pledget such that it cannot be separated from it.  The cover extends beyond the trailing end of the pledget in the form of a flexible sheath.  The sheath is sized and configured to easily receive and encircle a finger of the user and is designed to prevent soiling of the finger during insertion of the tampon into her vagina. The sheath can collapse upon itself once the pledget is inserted into the woman's vagina.  The sheath also provides a reliable means for removing the tampon from her vagina in a clean and easy manner.  The method of forming the tampon is also disclosed.  The method includes forming an absorbent ribbon having a predetermined width. Positioning the absorbent ribbon over a cover with a portion of the cover having a width greater than the width of the absorbent ribbon. The absorbent ribbon and the cover are then cut to a desired length and both materials are rolled into a cylindrically shaped softwind. The softwind has a portion of the cover material extending longitudinally outward from one end in the form of a flexible sheath. The softwind is then radially compressed into a pledget and the insertion end of the pledget is rounded to facilitate it's insertion into a woman's vagina.

Title: A plasma accelerator of short length with closed electron drift
Inventor: VALENTIAN DOMINIQUE
IPC: H05H1/54
Filed: 1993-06-21
Abstract: 32 A PLASMA ACCELERATOR OF SHORT LENGTH WITH CLOSED ELECTRON DRIFT The means (31 to 33, 34 to 38) for generating a magnetic field in the main channel of the plasma accelerator are adapted to produce, in the main channel (24) an essentially radial magnetic field at the downstream end (225) of the channel (24), its induction being maximum at this point. The magnetic field has a minimum induction in the transition area in the vicinity of the anode (25), the absolute induction value of the field increasing again upstream of the anode (25), in the region of the buffer chamber (23) in order to produce a magnetic mirror effect. The magnetic field lines include, between the anode (25) and the downstream end (225) of the channel (24), a concavity oriented downstream, causing focusing of ions, the maximum ionisation density area being located downstream of the anode (25). The magnetic field generating means comprise several distinct magnetic field generating means (31 to 33) and inner (35) and outer (34) radial, plane pole pieces (34, 35) disposed at the outlet face on either side of the main channel (24) and linked to one another by a central core (38), a yoke (36) and a peripheral magnetic circuit (37) axially disposed outside of the main channel (24). The yoke (36) consists of radial elements located in the immediate vicinity of the anode (25) and passing through the annular buffer chamber (23), thereby creating spaces (13) for communication between the annular buffer chamber (23) and the main channel (24).

Filed: 1995-03-01
Abstract: A scanner of this invention can read an object to be read having a width larger than that of the distal end portion of a scanner main body when the object is read by bringing the scanner main body close to or into contact with the object to be read.  An exit opening for outputting a light beam externally is formed at the distal end portion of the scanner main body.  An LED for generating a light beam, and a solid-state image pickup element for receiving the light beam which is generated by the LED, is output via the exit opening to have a predetermined irradiation width, and is reflected by a barcode, are arranged in the scanner main body.  A gap portion for increasing the irradiation width of the light beam to be larger than the width of the distal end portion of the scanner main body at the position of the distal end portion is formed at the distal end portion of the scanner main body having the exit opening.  Therefore, when a barcode is read by bringing the scanner main body close to or into contact with the barcode, the gap portion can increase the width of the light beam to be larger than that of the distal end portion at the position of the distal end portion of the scanner main body, and therefore, a barcode having a width larger than the width of the distal end portion of the scanner main body can be read.
