Abstract:
Improved tires designed for use in an improved tire/vehicle system having two pneumatic front tires and two pneumatic rear tires are especially effective when utilized on vehicles with a suspension system having limited camber, as in a live axle suspension system. The tires include a support member which is molded to the inboard sidewall of one or more tires in the tire/vehicle system. The inboard sidewall of a tire provides improved lateral stiffness in the tire, for cornering, and functions similar to cambering in tire/vehicle systems where cambering is not possible or where camber adjustment is limited.
Abstract:
A multi-chambered tire assembly (10) is provided by a pneumatic outer tire (12) mounted upon a rim (16) of a wheel and having an inner tire (14) or shield which is also mounted upon the rim (16). The inner tire (14) has a crown portion (36) spaced from the outer tire and a pair of sidewalls (38) each extending from the crown to a bead portion (40, 42). At least one of the bead portions (42) of the inner tire (14) forms an air passage way (44) between it and the adjacent bead (22) of the outer tire and is provided with radially extending grooves (52) connecting the air passage way with the outer air chamber (32).
Abstract:
A number of integrated circuit dies having on board protection against electrical overstress (EOS) transients are provided. Generally, the devices have an integrated circuit die with an outer periphery and a functional die area. A plurality of conductive input/output pads are formed on the integrated circuit die. Typically, a first conductive guard rail is disposed on the integrated circuit die and forms a gap between each one of the input/output pads. A voltage variable material is disposed in the gaps between the conductive guard rail and the input/output pads. Typically, a plurality of electrical leads are electrically connected to a respective one of the plurality of conductive input/output pads. At normal operating voltages, the voltage variable material is non-conductive. However, in response to an EOS transient, the voltage variable material switches to a low resistance state, providing a conductive path between the conductive guard rail and the input/output pads.

Antisense compounds, compositions and methods are provided for modulating the expression of MP-1. The compositions comprise antisense compounds, particularly antisense oligonucleotides, targeted to nucleic acids encoding MP-1. Methods of using these compounds for modulation of MP-1 expression and for treatment of diseases associated with expression of MP-1 are provided.
Abstract:
A prosthetic cement spacer for controlling the thickness of cement applied between a prosthetic insert and a support member, such as an acetabulum, includes a generally cylindrical standoff body portion fabricated from acrylic bone cement and a pointed wire concentric with said standoff body and outwardly extending from one end a sufficient length to anchor into the acetabulum bone surface. The method of use of these prosthetic cement spacers involves preparation of the acetabulum so that there is sufficient clearance space for the prosthetic cement spacers and then to insert the pointed wires into the acetabulum bone surface in an equilateral triangular arrangement thereby providing three points of contact for the prosthetic insert, such as an acetabular cup. By selecting three prosthetic cement spacers all having substantially the same standoff body height, the clearance region between the acetabulum bone surface and the acetabular cup is controlled and provides a uniform cement thickness throughout thereby providing an improved bonding arrangement.
Abstract:
A method and apparatus is provided for using a distributed multi-path QoS-aware routing scheme that considers basic MANET characteristics to meet transport service requirements of real-time applications and makes use of multiple discovered paths to calculate a next-hop decision. The QoS Routing scheme superimposes distributed neighborhood congestion, neighborhood density, and link stability and delay information over the multiple discovered paths when the next-hop decision is calculated.
Abstract:
The present invention provides a method for heat treating a polymer PTC composition to increase the peak resistivity of the composition making it especially well suited for high voltage applications. A polymer PTC composition having a melting point temperature Tmp is provided. The temperature of the polymer PTC composition is increased at a rate, r1, to a temperature greater than Tmp. The temperature of polymer PTC composition is held at the temperature greater than Tmp for a predetermined period of time. Then the temperature of the polymer PTC composition is decreased to a temperature less than Tmp at a rate, r2, wherein r2 is greater than r1.
Abstract:
A node in a wireless communication network comprises a processor that receives information regarding a first plurality of packets to be transmitted in an epoch, a first path of nodes for the first plurality of packets, and a first flow rate. The processor receives information regarding a second plurality of packets to be transmitted in the epoch, a second path of nodes for the second plurality of packets, and a second flow rate. The processor determines weights for the paths based on the flow rates. The processor assigns pipelines for the paths and creates groups of pipelines based on the weights. The groups may be assigned to a schedule.
