Title: Fluid transfer and diagnostic system for treating the inner ear
Inventor: ARENBERG IRVING K
IPC: A61F11/00
Filed: 1999-07-12
Granted: 2009-01-13
Abstract: This invention is an apparatus (10) for delivering fluid materials into, and out of the inner ear (204) via the round window membrane (206). A fluid transfer conduit (12) is provided which includes one or more passageways (22, 34, 162) therethrough which may have a semipermeable membrane (130) associated therewith to control fluid flow.  Attached to the conduit (12) is an inflatable bladder (46) sized for insertion within the round window niche (210). When inflated, the bladder engages the internal side wall (214) of the niche (210), thereby securing the bladder, and part of the conduit within the niche (210). Bladder inflation may be achieved through one of the passageways (34) within the conduit which can deliver an inflation fluid into the bladder.  Also, the conduit (12) may include an elongate conductive diagnostic member (102) for transferring electrical potentials to, and from the inner ear.

Title: Optimizing transmission of multimedia services in a mobile communication network
Inventor: KELLER WALTER
IPC: H04Q7/00
Filed: 1999-09-08
Granted: 2008-12-02
Abstract: The invention relates to a method for the optimized transmission of multimed ia services in mobile communications networks, notably mobile telephone network s. The invention relies on the fact that, unless the complexity of the transmission system is increased, the bit error rate of especially the air interface is considerabl y higher than that of comparable fixed connections. However, at least at the level of the air interface transmission methods can be optimized with regard to spectrum economy (transmission bandwidth) and transmission quality if specifically optimized transmission methods are used for the different application-specific data structures such as speech, synchronous data transmission, image transmission, data packet transmission or message transmission, as is, for example, specified in the GSM network in the form of services. Th e invention aims to provide a solution to the above transmission problems. To this end o ne device each is placed on either side of the transmission sections concerned. Said devices communicate with each other and divide an integrated multimedia data flow in to its application-specific data structures, transport the individual segments via transmission channels of the mobile telephone network which have been specially optimized for this particular purpose and then merge said segments to a transparent data flow which is identical to the original one.

Title: Method for measuring the activity of deacetylase and method of screening for inhibitors and accelerators of the enzyme
Inventor: TAMAI KATSUYUKI
IPC: C12N15/09
Filed: 2000-11-29
Granted: 2011-01-04
Abstract: The acetylation level of a peptide is evaluated by taking advantage of the fact that a change in the acetylation level affects the peptidase sensitivity of a substrate peptide. This method is usable in measuring the activity of a deacetylase or an acetylase. It is also possible to screen a substance affecting the activity of these enzymes thereby. Thus, the activity of a deacetylase can be conveniently measured.

Inventor: VALYUNIN IGOR
IPC: B29D11/02
Filed: 2000-12-21
Granted: 2010-02-16
Abstract: A method of preparing phakic intraocular lenses from hydropho-bic materials is described. In this process, the lens is tested to determine whether it can float submerged in an aqueous medium. If it cannot (e.g., if it remains on top of the aqueous medium), the lens is surface treated (for example, by vacuum UV or corona discharge processes) to increase its wetting ability (e.g., to reduce it hydrophobicity). The lenses prepared by this process are also described.

Abstract: Un dispositif de mesure est présenté qui détermine les propriétés d'un fluide à partir des fréquences de vibration d'une cavité représentative. Dans une réalisation, le dispositif de mesure comprend un tube d'écoulement représentatif, une source de vibrations et un détecteur installé sur le tube, ainsi qu'un module de mesure. Le tube d'écoulement représentatif reçoit un écoulement de fluide représentatif en vue de la caractérisation. Le module de mesure emploie des sources de vibrations pour produire des vibrations dans le tube. Le module de mesure combine les signaux du détecteur de vibrations dans le tube pour déterminer les propriétés du fluide représentatif, comme la densité, la viscosité, la compressibilité, la fraction d'eau et la taille des bulles. Le module de mesure peut également détecter des motifs d'écoulement comme l'écoulement bloc. Pour mesurer la densité du flux représentatif, le module de mesure détermine la fréquence de résonance du tube de flux représentatif. La densité peut ensuite être calculée selon une formule qui compense la température et la pression du système. D'autres propriétés de fluide peuvent être déterminées à partir de l'amplitude de résonance du tube d'échantillon, la largeur du pic ou la forme du pic. La variation des mesures de densité peut être utilisée pour détecter et caractériser un écoulement de fluide à plusieurs phases. Une source de vibrations et un détecteur sont disposés d'une manière qui améliore grandement la précision et la fiabilité du dispositif de mesure sur une plage de températures, de pressions et d'accélérations de choc comme ceux qui peuvent être présents dans le fond de trou d'un puits.

Abstract: In a method of driving a passive matrix display or memory array of cells comprising an electrically polarizable material exhibiting hysteresis, in particular a ferroelectric material, wherein the polarization state of individual cells can be switched by application of electric potentials or voltages to word and bit lines in the matrix or array, a potential on select ed word and bit lines is controlled to approach or coincide with one of n predefined potential levels and the potentials on all word and bit lines are controlled in time according to a protocol such that word lines are sequentially latched to potentials selected among nword potentials, while th e bit lines are either latched sequentially to potentials selected among nbit potentials, or during a certain period of a timing sequence given by the protocol connected to circuitry for detecting charges flowing between a bit line or bit lines and cells connecting thereto. This timing sequence is provided with a read cycle during which charges flowing between the selected bit line or bit lines connecting thereto are detected and a "refresh/write cycle" during which the polarization of the cells connecting with selected word and bit lines are brought to correspond with a set of predetermined values.

Abstract: A method and apparatus for calibrating the air flow in a respirator system is provided. The method provides for the establishment of control set points in a true calibration protocol through the simple triggering of the microprocessor of a controller. When the trigger is initiated, the microprocessor engages and provides the logic for the calibration cycle. The calibration cycle proceeds until a second trigger terminates the process and establishes the control set points. The calibration sequence of the method relies only on an initiation and termination trigger that is facilitated by components integral to the apparatus.
