Abstract: A system includes a direct radiating array antenna and one or more processors. The antenna includes an array of elements configured to radiate radiofrequency (RF) energy to form a beam having multiple frequency channels. The one or more processors are configured to generate an excitation plan for powering the elements to form the beam. The excitation plan assigns multiple corresponding beamforming coefficients to each element in a group of the elements. Each beamforming coefficient designates power allocated to the assigned element for radiating RF energy at an associated frequency channel. The excitation plan provides a substantially uniform power distribution among the elements in the group, and at least some of the elements in the group have different allocations of power among the multiple frequency channels of the beam than other elements in the group.

Abstract: A suspended weight barbell attachment apparatus, having a barbell assembly with first and second distal ends. Further having two actuating assemblies, each with a housing assembly having an interior wall, an exterior wall, and a hole that extends from the interior wall to the exterior wall. The housing assembly further has a reinforced section. The hole has a cooperative shape and dimension to house a respective reinforced section therethrough. Each reinforced section receives a respective first or second distal end. Each of the two actuating assemblies further has a handle assembly, and a locking assembly. Further having two post assemblies, each with vertical walls, a top end, and a bottom end. The vertical walls have a plurality of notches. Each housing assembly is slidably positioned between the vertical walls of a respective post assembly. And further having two base frame assemblies.

Abstract: A tire has a tread pattern with superior performance characteristics. The tread pattern includes a generally oval shaped lug pattern having sidewalls that are of a variable angle. The sidewalls are also formed at an angle with respect to a vertical axis. The transitions between the sidewalls, as well as between the sidewalls and the oval shaped lug pattern have rounded edges to reduce stress components. A base of the lug is generally rectangular with convex sides.

Abstract: Tire having a tread pattern with superior performance characteristics. The tread pattern includes ribs and circumferential grooves which are at least one of tapered and/or generally V-shaped. The walls of each circumferential groove have a wavy and/or sinusoidal contour extending in a generally circumferential direction.

Abstract: An absorbent lid or cover for a hermetic enclosure comprises a coating applied via sputtering to at least a portion of at least one surface of the lid and consisting of at least one elemental metal selected from the group consisting of silicon, germanium and titanium. Adsorbent inserts for such enclosures that are either sputter-coated or sputter-shaped with the aforementioned elemental metals are also disclosed, as are methods for making such covers, inserts and enclosures.

Abstract: A computer processor architecture which employs an on-chip cache macro and an on-chip memory map is described. The memory map contains indicia of the cachability of different segments of off-chip memory, preferably along with an indication of the read/write status of each off-chip memory segment. A processor generated address signal is then compared on-chip with the memory map to ascertain whether the generated signal falls within a segment which is cachable or uncachable and which is read-only or read/write.
