Abstract:
Systems and methods for validating a circuit design are described. The circuit validation includes determining a subset of checks to apply to a portion of the overall circuit based on the pin type composition of the circuit portion.
Abstract:
Methods, devices and systems facilitate diagnosis, and in some cases treatment, of back pain originating in intervertebral discs. Methods generally involve introducing one or more substances into one or more discs using a catheter device. In one embodiment, a patient assumes a position that causes back pain, and a substance such as an anesthetic or analgesic is introduced into the disc to determine whether the substance relieves the pain. Injections into multiple discs may optionally be performed, to help pinpoint a disc as a source of the patient's pain. In some embodiments, the catheter device is left in place, and possibly coupled with another implantable device, to provide treatment of one or more discs. A catheter device includes at least one anchoring member for maintaining a distal portion of the catheter within a disc.
Abstract:
The invention relates to a flywheel magneto generator having a rotor assembly and a stator assembly. The rotor assembly includes a non-ferromagnetic flywheel and a plurality of magnetic poles that are positioned in spaced relationship around the circumference of the flywheel. The stator assembly includes an E-shaped core with a single magnet mounted on the center leg and coils associated with at least the outer legs. The poles and core may be formed of a bonded iron material. The poles may be joined to the flywheel by press fitting or integral molding, among other methods.
Abstract:
The process of the present invention purposefully precipitates a portion of the dissolved lignin onto pulp fibers to improve pulp yield of unbleached pulp. The resulting retention of lignin on the pulp creates an increase in pulp yield. Washing the pulp in a series of washer stages sequentially removes entrained lignin. Between each of the washer stages, adding dilution water repulps a pulp mat that exits from a prior washer stage and creates a pulp stream for a next washer stage. After at least one of the washer stages, adding an acidifying agent to the pulp stream forms a pulp product by precipitating the entrained lignin onto cellulosic fibers contained in the pulp stream. Finally, the process removes the pulp product from the series of washer stages with the pulp product having at least about a 1 unit increase in Kappa number.
Abstract:
An engine, e.g., a cam drive, barrel-type internal combustion engine, that includes: a main drive shaft defining a longitudinal axis; a sinusoidal main drive cam rigidly attached to the main drive shaft; a plurality of cam members that are in contact with the sinusoidal main drive cam and that are configured to follow the sinusoidal main drive cam, wherein rotation of the sinusoidal main drive cam corresponds to reciprocating linear movement of each of the plurality of cam members in a direction parallel to the longitudinal axis; for each cam member, a pair of linear pistons disposed on opposite sides of the cam member for reciprocating linear movement within respective cylinder bores.

Abstract:
A wheel unit (10) comprises a wheel rim (12), a pneumatic tyre (14) receivable on the wheel rim (12) and a runflat assembly (16) adapted to be seated on the wheel rim (12) to close off a well (22) provided in the wheel rim (12). The runflat assembly (16) includes an annular support body (24) which is radially expandable to an expanded condition and contraction means (28,30) adapted to be operated via an opening (78) formed in the wheel rim (12). The contraction means (28, 30), when activated, is operable on the support body (24) to cause the support body (24) to be contracted to a radially contracted condition. The contraction mean is accessible through the opening (78) to cause the support body (24) to be radially contracted to seat the runflat assembly (16) on the wheel rim (12) to close off the well (22). The support body (24), when in its contracted condition, has a diameter greater than that of the wheel rim (12).
Abstract:
A sorption cooling system for providing cooled air to the cabin of a vehicle. The sorption cooling system includes an evaporator, a condenser adapted to fluidly communication with the evaporator, and a plurality of adsorbent beds adapted for fluid communication with the condenser and the evaporator. Each adsorbent bed includes a fluid impermeable casing, desiccant sheets having apertures therethrough, a refrigerant flow path for flowing a refrigerant proximal to a first side of the desiccant sheets, and a coolant flow path for flowing a coolant fluid proximal to a second side of the desiccant sheets. The apertures are a portion of one of the refrigerant and coolant flow paths.
