Title: Fingerprint registering method and fingerprint checking device
Inventor: YAMAGUCHI MASAHIKO
IPC: G06T7/00
Filed: 1996-08-26
Abstract: A method intended to accomplish reliability and easiness of fingerprint registration by expressing quality of fingerprint images by the number of pseudo-feature points, improve security of fingerprint registration in an entrance/exit management system, detect as correctly as possible the contour direction of the fingerprint, remarkably improve safety of fingerprint collation, hold registered fingerprint data of each gate as fingerprint data by collecting updated registered fingerprint data as the latest fingerprint data in a host apparatus, improve operation factor by making it possible to use an identification number of fewer digits, and register fingerprints having a high collation ratio by automatically applying a spatial filter processing only in a re-registration processing. In the fingerprint registration method, normal feature points and pseudo-feature points of the fingerprint obtained through an imaging device are detected, the number of the pseudo-feature points inside a registration window having the regular feature point as its substantial center are counted, the mean number of pseudo-feature points inside the registration window is determined from the sum of the pseudo-feature points inside the entire registration windows, and the fingerprint registration processing is executed when this mean pseudo-feature point number is samller than a threshold value.
Patent CA-2201841-A1 (CA)
Inventor: CATZ INGRID
IPC: A61K38/08
Filed: 1997-04-04
Abstract: Human myelin basic protein (h-MBP) has a molecular weight of 18.5 KD and contains 170 amino acid residues. Synthetic peptides ranging in length from about 8 to 25 residues and covering the entire length of the protein have been produced. Antibodies to h-MBP (anti-MBP) were found to be neutralized by the synthetic peptides, in vitro, which span the h-MBP from about amino acid residue 61 to about amino acid residue 106. The peptides, which cover both the amino (about residues 1 to 63) and carboxy (about residues 117 to 162) terminals of h-MBP did not neutralize purified anti-MBP. Intrathecal administration of peptide MBP75-95, either as a single dose, or as repeated injections for periods up to 10 weeks, produced complete binding-neutralization of free (F) anti-MBP with no change in bound (B) levels. A control peptide MBP35-58 had no effect on F or B anti-MBP levels. Intravenous administration of MBP75-95 resulted in significant decline of F and B CSF anti-MBP levels over a period of one month. Administration of MBP synthetic peptides to MS patients either intrathecally or intravenously did not have any adverse neurological effe cts and systemic complications did not occur. The MBP epitope for MS anti-MBP has been localized to an area between Pro85 and Pro96. The longer peptide Asp82 to Thr98 is more soluble and thus can be administered in a smaller dose.

Title: Continuous passive motion device for upper extremity forearm therapy
Inventor: SARINGER JOHN H
IPC: A61H1/00
Filed: 1997-09-26
Abstract: A continuous passive motion (CPM) device for the synovial joints and surrounding soft tissue of the human body, more specifically to the upper extremities. The device includes an upper arm support suitably fixed to a drive actuator and a adjustable forearm support attached to the rotational center of the drive actuator so that pivotal movement of the output causes the forearm support to pivot about an axis parallel to a longitudinal axis of the forearm support.   Various cuffs are provided so a patient can secure their upper arm above the elbow and the upper forearm below the elbow to the device with the actuator located either forward of or behind the elbow. The rotational motion of pronation and supination is created by aligning the rotational center of the actuator output with the anatomical rotational center of the forearm. The rotational centers are concentric to minimize stresses on the affected limb. The relative rotational motion between the upper support and forearm support creates the passive anatomical motion of pronation and supination.
