A structure having a coplanar waveguide transistor; and a microwave section, coupled to the transistor, having: a strip conductor coplanar with the electrodes of the coplanar waveguide transistor and a ground plane conductor disposed under the strip conductor.

Micropstrip transmission line/coplanar waveguide (CPW) transistor structure

A method, apparatus, and article of manufacture for accessing a subject table in a computer system. The subject table is partitioned across a plurality of processing units of the computer system. A user query or other request to access the subject table is split into a plurality of step messages, wherein each of the step messages is assigned to one of the processing units managing one or more of the partitions of the subject table. A plurality of actions are identified for each of the step messages, and one or more necessary records for these actions are retrieved from the partition of the subject table and stored into a corresponding partition of a spool table. The necessary records are selected in such a manner that none of the actions involved in the request need to access the partition of the subject table. The actions from the step message are then performed against the partitions of the spool table rather than the partitions of the subject table. An optimizer function uses information from the spool table to generate more efficient execution plans for the step message and its associated actions.

A point-to-point radio frequency unit/antenna has a flat antenna, preferably a continuous transverse stub antenna, integrated into the housing of the microwave unit. The radio frequency unit/antenna includes a housing having an exterior wall, a microwave radio frequency transceiver electronics package within the housing and having an antenna connection, and a flat antenna affixed to one face of the exterior wall of the housing. A microwave radio frequency feed communicates between the flat antenna and the antenna connection of the microwave transceiver electronics package. There is preferably a bracket structure on another face of the housing to affix the housing to a support.

Integrated flat antenna and radio frequency unit for point-to-point microwave radios

A method, apparatus, and article of manufacture for accessing a subject table in a computer system. The subject table is partitioned across a plurality of processing units of the computer system. A trigger is defined for the subject table, such that when a triggering event occurs on the subject table, a triggered action is performed. Both the triggering event and triggered action can be performed in parallel by the computer system. A spool table is generated for each partition of the subject table, wherein the spool table stores one or more necessary records accessed from the subject table by the triggering event. In this manner, triggered actions that refer to these necessary rows need not access the subject table again.
