Abstract: A two-wheeled roller skate with canted wheels has an axle for the forward wheel located well forward of the ball of the foot. The axle for the rear wheel is located at the rear of the skater's heel. The wheels are canted so that the front and rear wheels contact the ground on the opposite sides of the center line of the skater's foot. In plan projection, the axles are preferably non-parallel in order to provide steering correction. The amount of steering correction desirable will depend on the skater's skill and the nature of the skating activity. In alternative embodiments, the present invention incorporates novel braking mechanisms.

Title: Apparatus and method for using bubble as virtual valve in microinjector to eject fluid
Inventor: KIM CHANG-JIN
IPC: F02M53/04
Filed: 1999-01-22
Granted: 2005-12-20
Abstract: An apparatus and method for forming a bubble (30) within a microchannel of a microinjector (12) to function as a valve mechanism between the chamber (14) and manifold (16), that provides for a high resistance to liquid exiting the chamber through the manifold during fluid ejection through an orifice (18) and that also provides a low resistan ce to refilling of liquid into the chamber after ejection of fluid and collapse of the bubble. This effectively minimizes cross talk between adjacent chambers and increases injection frequency of the microinjector. The formation of a second bubble (32) within the chamber (14) coalesces with a first formed bubble (30) between the chamber (14) and manifold (16) to abruptly terminate the ejection of fluid, thereby eliminating satellite droplets.

Granted: 2005-03-01
Abstract: A soy protein-containing dry cheese sauce mix containing significant levels of soy protein is provided. The dry cheese sauce mix is prepared by mixing soy flour with dried cheese and cheese flavoring. When used, the dry sauce mix is hydrated to form a cheese sauce suitable for use with starch-based products (e.g., pasta, rice, and the like). The soy protein-containing dry sauce mix of this invention generally contains about 10 to about 75 percent soy flour, about 25 to about 90 percent cheese powder, and about 1 to about 5 percent cheese flavoring. Preferably, the soy protein-containing dry sauce mix contains about 25 to about 50 percent soy flour, about 25 to about 50 percent cheese powder, and about 1 to about 5 percent cheese flavoring. The present invention allows the use of significant levels of soy protein to be included in a sauce for a starch-based product (e.g., macaroni and cheese) and, thereby, provide the health benefits of soy without adversely effecting the organoleptic or other sensory properties of the product.

Abstract: A system and method of relating a public key to a compact identification string in a digital certificate to enable an entity to construct a certificate chain from a root certificate authority to an end-entity efficiently and further allow a certificate holder to store only its identifier, thus providing privacy protection, and present this in place of a digital certificate for authentication rather than storing and presenting its certificate or a chain of certificates representing the certificate path up to the root certificate authority. In a preferred embodiment, the certificate authority generates unique identifier for each certificate consisting its pseudonym concatenated with the pseudonyms of other sub--certificate authorities in the certificate chain between it and the certificate holder, concatenated with certificate holder's pseudonym. The pseudonyms are generated by the entity known by the pseudonym or the entity certifying a binding between the pseudonym and the entity's public key.

Abstract: A radar monopulse signal receiving system according to an aspect of the invention provides sum (.SIGMA.) and a single difference (.DELTA.) beam outputs from the beamformer. This is accomplished by encoding the information relating to the azimuth and elevation difference beams onto a single complex number. By comparison with some prior-art arrangements, the number of channels required for processing the signals is reduced. Near the end of the monopulse processing, the quotient is taken of complex number divided by the sum beam information, which directly produces a complex monopulse ratio m=m A +jm E. The azimuth and elevation monopulse ratios are represented by m A and m E, respectively.

Granted: 2007-10-02
Abstract: Microfluidic embryo scaled channels (14) for handling and positioning embryos provide the opportunity to evaluate and treat embryos in improved manners.  Fluid flow is used to move and position embryos within microfluidic channels and channel geometrics may be used to place embryos at specific locations.  Surface properties and compliance (deformation) properties of embryos are evaluated as a predictor of viability. The microfluidic channels provide the opportunity for fine controls of pressure to conduct various evalutions at forces slightly below which damage to embryos is known to occur. Measurement of the distance and/or which embryos roll in a same pressure gradient microfluidic channel provides information, with healthy embryos traveling slower or a shorter distance as they demonstrate more stiction to channel walls.

Granted: 2007-01-09
Abstract: A window allows the introduction of radiation energy into an annular processing chamber (44) filled with a material to be processed. The chamber is formed from coaxial cylinder members (30,32) rapidly rotating relative to one another. The chamber (44) can be thin enough so that it is short compared to the penetration depth of the radiation through the material, providing even exposure of the material to the radiation. Also, eddies created in the material by the relative rotation enhances the even exposure. When the material inside the annular processing chamber (44) is opaque, resulting in an insignificant penetration depth, the eddies still insure that the material is evenly exposed to the irradiation.

Abstract: The patent discloses a signal processing technique for determining the fast and slow shear wave polarizations, and their orientation, for acoustic waves in an anisotropic earth formation. The signal processing method decomposes composite received waveforms a number of times using a number of different spike angles. The decomposed signals are used to create estimated source signals. The estimated source signals are compared in some way to obtain an objective function. Locations in a plot where the objective function reaches minimum values are indicative of the acoustic velocity of the fast and slow polarizations within the formation.
