Title: Vacuum apparatus and method for managing residual limb volume in an artificial limb
Inventor: CASPERS CARL A
IPC: A61F2/50
Filed: 2001-11-19
Abstract: A hypobarically-controlled artificial limb for amputees includes a single socket with a volume and shape to receive a substantial portion of the residual limb (14). A liner (92) with a volume less than the residual limb (14) is donned over ,the residual limb, with the liner (92) tensioned into a total contact relationship with the residual limb (14). A sealed cavity is formed between the socket, (60) and the liner (92). A vacuum source (70) is connected to the socket cavity (62) thereby drawing the residual limb (14) and liner (92) into firm and total contact with the socket (60). To compensate for some air leakage past the, seal (140), there is a mechanism to maintain the vacuum in the cavity.

Title: Method and apparatus for improving the accuracy of noninvasive hematocrit measurements
Inventor: SCHMITT JOSEPH M
IPC: G01N21/35
Filed: 2002-03-13
Abstract: A device and a method to provide a more reliable and accurate measurement of hematocrit (Hct) by noninvasive means. The changes in the intensities of lig ht of multiple wavelengths transmitted through or reflected light from the tiss ue location are recorded immediately before and after occluding the flow of venous blood from the tissue location with an occlusion device positioned ne ar the tissue location. As the venous return stops and the incoming arterial blood expands the blood vessels, the light intensities measured within a particular band of near-infrared wavelengths decrease in proportion to the volume of hemoglobin in the tissue location; those intensities measured with in a separate band of wavelengths in which water absorbs respond to the difference between the water fractions within the blood and the displaced tissue volume. A mathematical algorithm applied to the time-varying intensities yields a quantitative estimate of the absolute concentration of hemoglobin in the blood. To compensate for the effect of the unknown fractio n of water in the extravascular tissue on the Hct measurement, the tissue wate r fraction is determined before the occlusion cycle begins by measuring the diffuse transmittance or reflectance spectra of the tissue at selected wavelengths.
Patent CA-2441770-A1 (CA)
Title: Highway/rail trailer axle/suspension lift assembly
Inventor: HESS TIMOTHY V
IPC: B60G9/00
Filed: 2002-04-16
Abstract: An air-free, relatively lightweight lift assembly for an axle/suspension system of a highway/rail convertible semi-trailer, utilizes a transversely-oriented coil torsion spring having a relatively low spring rate. The torsion spring is captured between a stationary plate and a rotatable plate. A  flexible link is pivotally attached at its upper end to the rotatable plate and at its lower end to the axle. This assembly results in a variable rate moment arm and continuously increasing leverage when the suspension air spring is overinflated to lower the system for transfer of the trailer from a highway tractor to a rail bogie, thus enabling use of a less robust air spring. The assembly conversely creates a decrease in leverage at the lifted rail transport position, to securely maintain the axle/suspension system in the rail position. For highway use, the lift assembly provides suspension damping without shock absorbers.

Patent CA-2458427-A1 (CA)
Inventor: HETHERINGTON PHIL
IPC: H04R3/00
Filed: 2004-02-18
Abstract: The invention includes a method, apparatus, and computer program to selectively suppress wind noise while preserving narrow-band signals in acoustic data. Sound from one or several microphones is digitized into binary data. A time-frequency transform is applied to the data to produce a series of spectra. The spectra are analyzed to detect the presence of wind noise and narrow band signals. Wind noise is selectively suppressed while preserving the narrow band signals. The narrow band signal is interpolated through the times and frequencies when it is masked by the wind noise. A time series is then synthesized from the signal spectral estimate that can be listened to. This invention overcomes prior art limitations that require more than one microphone and an independent measurement of wind speed. Its application results in good-quality speech from data severely degraded by wind noise.

Title: Vibration-dampening drill collar
Inventor: CLARK BRENT ALEXANDER
IPC: E21B47/017
Filed: 2004-04-01
Abstract: A drill collar primarily for use with measurement-while-drilling and logging-while-drilling sensors, the drill collar composed of a non-magnetic nickel alloy, and having three or four elongate nitral elastomer ribs parallel the longitudinal axis and mounted on the inner surface of the drill collar, defining a central aperture for receiving the down-hole sensor and inter-rib apertures for receiving drilling fluid. This novel drill collar is especially useful in rough or underbalanced drilling applications, protecting the sensor and enhancing measurement accuracy by dampening flow-based harmonic vibrations, absorbing vibration from lateral tool movement, and stabilizing/centralizing the sensor within the central aperture.  Also, the novel drill collar allows the operator to run lower fluid rates while drilling, minimizing formation damage from fluid invasion.

Title: Delivery of mobile station operational and self-performance test results to network in response to encrypted request message
Inventor: TERVO TIMO P
IPC: H04W12/03
Filed: 2002-09-30
Abstract: A mobile station (10) and wireless system (32) operates in accordance with a method that has steps of: (A) during the operation of the mobile station, determining and storing a set (24A) of performance-related data (PPCs) in th e mobile station; and (B) responsive to an occurrence of a triggering event, transmitting the set or a sub-set of the PPCs to a computer (33A) for analysis. The PPCs can be stored in physical counters and registers or in memory locations that are managed to function as counters and registers. The PPCs can include a count of dropped calls, and/or an indication of a result of a mobile station self-test mode of operation. The triggering event can be a receipt by the mobile station of a message to transmit the set or sub-set of the performance-related data, or a receipt by the mobile station of an input from a user of the mobile station, or an expiration of a timer, or at least one of the PPCs being equal to a threshold value. The step of transmitting t he set or a sub-set of the PPCs can include steps of receiving the transmitted PPCs at a control center (33) associated with a network service provider and/or at a (remote) diagnostic center (38); and then analyzing the data wit h the computer (33A) to determine an indication of an occurrence of at least o ne of a fault in the mobile station, a fault in a system of the network service provider or a no fault condition. An optional step transmits the determined indication to the mobile station. The analysis may further include determini ng statistical information regarding a population of mobile stations. For the case where the triggering event is the reception of a wireless message, the message may be in the form of an encrypted message to transmit the set or su b- set of the performance-related data. In this case the mobile station operate s to decrypt the received message using an associated public key stored in the mobile station and to transmit the set or the sub-set of the performance- related data only in response to correctly decrypting the encrypted message.
