Abstract:
A tuned vibration mass damper for isolating vibrations from the steering wheel or other vehicle component includes an elastically cantilever mounted lead mass and a unitary thermoplastic bracket member made from a super tough plastic material and including a first or coupling portion for coupling the tuned vibration damper to a structure of the vehicle, a second portion for coupling the unitary bracket member to the lead mass, and an intermediate bight portion. The second coupling portion includes a plurality of cylindrically shaped legs extending through holes in the lead mass and having their ends formed (in a heading operation) to couple the unitary bracket member to the lead mass and a pair of travel limiters extending beyond the mass for preventing the mass from contacting other structures once the mass damper is installed.
Abstract:
Tire traction devices for various vehicles are described. Traction devices may comprise a tire traction assembly configured to be mounted on a tire, a pair of brackets configured to substantially straddle the sidewalls of the tire, and an attachment mechanism comprising first and second mating elements attached to opposite brackets, the attachment mechanism configured to releasably secure a traction assembly to the tire from the outward facing side of a vehicle on which the tire is mounted. Traction devices may optionally include a plurality of elastomeric tensioners positioned about the traction assembly, and/or one or more support cables configured to align the traction assembly.
Abstract:
Methods and systems for extraction of 3D geometry from a plurality of generalized camera images by a device that comprises an electronic circuit are provided. Methods include identifying an x and y coordinate, an orientation, and a scale for each of one or more feature locations in each of the generalized camera images, extracting a local image feature at each feature location, generating a feature camera centered on each feature location, identifying groups of feature cameras providing consistent triangulation opportunity, and triangulating each identified feature camera group by finding the 3D point that minimizes an error term.
Abstract:
A multi-monitor computer system includes a plurality of display devices communicating with at least one computing device executing an application management procedure. The application management procedure enables an application window available on one display device to be moved entirely to another display device by selecting the other display device from a dialog box displayed in response to a pointer-dragging input gesture on the application window.
Abstract:
An annular sealing element to seal between metal surfaces for use in flanges, joints, packers and the like, located in oil and gas exploration and production equipment. The sealing element has inner and outer metal deformable surfaces joined at ends, defining an interior volume which is entirely filled with a plastic deformable material. The surfaces are arranged such that on compression of the element from the ends, the element will deform in a controlled manner on a cantilever principle. The volume of filler and the interior volume remain substantially equal during compression so that delamination does not occur. Thus the sealing element provides a seal combining the flexibility of elastomer seals with the integrity of a metal to metal seal.
Abstract:
Techniques for conveying market information to users are described. The techniques are computer driven and involve receiving by one or more computers a data stream of current market values for the financial item, applying by the one or more computers the data stream to a rules engine to determine a change value corresponding to a change between a current value of the financial item and a historical value and using by the one or more computers the determined change value to retrieve an audio file according to a selected audio representation, with the change value corresponding to a defined status, e.g., price, trading volume level for the financial item.
Abstract:
A method to produce levulinic acid (LA) and gamma-valerolactone (GVL) from biomass-derived cellulose or lignocellulose by selective extraction of LA using GVL and optionally converting the LA so isolated into GVL, with no purifications steps required to yield the GVL.
Abstract:
A method for creating space in a joint, the method comprising: applying force to a body part so as to distract the joint and create an intrajoint space; inserting an expandable member into the intrajoint space while the expandable member is in a contracted condition; expanding the expandable member within the intrajoint space; and reducing the force applied to the body part so that the joint is supported on the expandable member.
Abstract:
An ultrasound acoustic assembly includes a number of ultrasound acoustic arrays, each array comprising an acoustic stack comprising a piezoelectric layer assembled with at least one acoustic impedance dematching layer and with a support layer. The acoustic stack defines a number of dicing kerfs and a number of acoustic elements, such that the dicing kerfs are formed between neighboring ones of the acoustic elements. The dicing kerfs extend through the piezoelectric layer and through the acoustic impedance dematching layer(s) but extend only partially through the support layer. The ultrasound acoustic assembly further includes a number of application specific integrated circuit (ASIC) die. Each ultrasound acoustic array is coupled to a respective ASIC die to form a respective acoustic-electric transducer module. Methods of manufacture are also provided.
Abstract:
A method and device for processing mammalian adipose tissue such that the vascular rich fraction is separated from the vascular poor fraction, Mammalian adipose tissue in the form of morselated surgical biopsies and/or lipoaspirate from liposuction is placed within a novel syringe attached to a detection device measuring either color, light saturation, infra-red light, heme, iron or oxygen saturation. This process involves no label and minimal manipulation and handling of the tissue. This process and device may also be used intra-operatively under sterile conditions for immediate use within the same individual receiving liposuction or surgery.
