Title: Two-axis ball-based cursor control with tactile feedback
Inventor: YU YAT SHUN DAMIEN
IPC: G06F3/0354
Filed: 2001-01-29
Granted: 2006-08-01
Abstract: A two-axis ball-based cursor control apparatus with tactile feeling is provided, which includes a housing; a spherical ball contained partially within the housing and having a plurality of recesses distributed about its outer surface; two pairs of spring biased sensor mechanisms each including a probe, a spring, and a transducer;  and a means for processing the signals received from the sensor mechanisms. Each of the four probes is positioned so that it rests within one of the recesses on the spherical ball when the ball is stationary. As the ball is rotated, the probes are pushed up and out of the recesses by the ball, causing the corresponding springs to alternately compress and decompress, before the probes come to rest in adjacent recesses. Each transducer generates an electrical signal corresponding to the rate of compression and decompression in the corresponding spring. The signal processing means then translates the signals from each of the transducers into movement of a cursor on an electronic display screen which corresponds to the rotation of the spherical ball about each of its axes.

Granted: 2012-01-17
Abstract: A method and an apparatus for interfering with pathological cells survival processes, i.e. inducing directly or indirectly apoptosis, on living pathological cells, by using magnetic fields without adversely affecting normal cells. Static (S) and extremely low frequency (ELF) magnetic fields are used having low intensity comprised between 1 and 100 mT, preferably comprised between 1 and 30 mT. In particular SELF fields are used which are different sequences of S and/or ELF fields, i.e. S fields followed by ELF fields, ELF fields followed by S fields, S and ELF fields together, as well as the presence of S or ELF fields alone, said ELF fields having a field frequency comprised between 1 and 1000 Hz. An apparatus for carrying out the method comprises means for generating static magnetic (S) fields crossing a working environment and/or means for generating electromagnetic extremely low frequency (ELF) fields over the working environment in addition to the S fields. Means are provided for mudulating the S fields associated to the S fields generating means and varying the intensity of the S fields from 1 to 100 mT, preferably between 1 to 30 mT according to a predetermined function. Means may also be provided for modulating the ELF fields associated to the ELF fields generating means and imposing to the ELF fields a frequency between 1 and 1000 Hz with intensity comprised between 1 to 100 mT, preferably between 1 and 30 mT according to a predetermined function.

Abstract: A curable, high temperature, carbonaceous, cement paste composition comprising a catalyst; a carbon filler present in an amount of about 20 to about 60 wt. %; a polymerizable monomeric system present in an amount of about 7 to about 30 wt. % comprising a dialkyl ester of an aromatic tetracarboxylic acid, an aromatic diamine, and a monoalkyl ester of an acid selected from the group consisting of 5-norbornene-2,3-dicarboxylic acid and phthalic acid; and a furan solvent present in an amount of about 20 to about 60 wt. %. The most preferred embodiment comprising a monomeric system comprising a dimethyl ester of 3,3',4,4'-benzophenonetetracarboxylic acid, 2,2'-bis (4-[4- aminophenoxyl]phenyl)propane and a monomethyl ester of 5-norbornene-2,3-dicarboxylic acid with furfuryl alcohol and a catalytic solution of about 50% ZnCl2, has a glass transition temperature of about 280°C after curing by heating at about 2°C/minute to about 240°C and holding for about 2 hours. Upon curing, the cement paste composition maintains a strength of at least about 2000 psi at room temperature after heat treatment at about 3000°C even when cured at a substantially lower temperature of at least about 200°C. Subsequent heating of the monomeric binder causes further cross- linking producing a stronger and more stable cement for use at service temperatures greater than the initial glass transition temperature of the cured cement. The curable cement composition may be used along with a pre-coat in an adhesive system for attaching together carbon bodies. Most preferably, the pre-coat comprises about 27 wt. %, of a monomeric system comprising a dimethyl ester of 3,3',4,4'-benzophenonetetracarboxylic acid, 2,2'-bis (4-[4- aminophenoxyl]phenyl)propane and a monomethyl ester of 5-norbornene-2,3-dicarboxylic acid dissolved in about 65 to about 85 wt. % furfuryl alcohol. A method of making the cement paste composition is also described.

Title: Electrosurgical device having a dielectric seal
Inventor: SCHOENMAN ARTHUR L
IPC: A61B19/00
Filed: 1999-09-21
Granted: 2010-12-07
Abstract: An electrosurgical device is provided having at least one elastomeric seal capable of providing bio-contamination and dielectric protection by inhibiting the ingress of fluids and contaminants through the nose and actuator areas. The elastomeric seal is manufactured from a thermoplastic elastomer or resin which while in liquid form is placed within a mold. A housing section having the main circuit components and mechanisms of the electrosurgical device is then placed within the mold. Once the elastomer cures, the elastomeric seal seals the components and mechanisms within the housing partial-section. The elastomeric seal defines a flexible first opening at a distal end of the electrosurgical device to accommodate varying diameters of electrodes or blades connected to the nose area of the elctrosurgical device. An actuator seal is also provided on the actuator area of the electrosurgical device to prevent fluids and contaminants from entering the electrosurgical device through the actuator area. The device is further provided with a plug connector having a counting mechanism for counting the number of times the device is plugged into an electric generator.  A disable mechanism is included at the proximal end of the plug connector to disable the device after a pre-determined number of operations.

Granted: 2004-08-03
Abstract: An apparatus for filtering thermoplastic synthetic plastic material has a screw bearingly supported within a housing for rotation around its longitudinal axis for the transport and preferably also plasticizing of the synthethic plastic material.  This material is supplied to the screw through an intake opening into the housing and leaves the housing through an exit opening. The screw is subdivided into two sections disposed one behind the other in axial direction. A filter provided with penetration openings is disposed in the flow of the synthetic plastic material that is disposed between these two sections, which filter is disposed within the housing between the two sections of the screw so that it subdivides the interior of the housing. The filter is connected for common rotation with at least one of the screw sections. At least one scraper mounted in the housing engages the upstream side of the filter and strips off coarse impurities from the filter when the filter is rotated and conveys the impurities into a collecting space that is in connection with the interior of the housing.

Title: Scaled-feedback turbo decoder
Inventor: HEINILA MARKO
IPC: H03M13/29
Filed: 2001-02-23
Granted: 2006-05-16
Abstract: An iterative Turbo decoder in which soft bits of a received signal are repetitively subjected to the process of decoding by a first decoder associated with a first encoder in the transmitter, interleaving by an interleaver associated with an interleaver in the transmitter, decoding by a second decoder associated with a second encoder in the transmitter, and deinterleaving by a deinterleaver associated with the interleaver in the transmitter. The improvement is to scale the signal after each decoding by a predetermined value in the vicinity of 0.7 to 0.8. At a signal Eb/No in the vicinity of 1.0 db., an improvement of about 0.2 db. in coding gain is attained while very little complexity is added. Decoders may be according to the max Log MAP algorithm instead of the more complex Log MAP algorithm with only slight degradation of performance.
