Abstract: A base station signal is applied to antenna elements. One signal from a first element is electrically modified and evaluated in conjunction with a second, unmodified signal from a second element. The modified signal is further modified and again evaluated with the unmodified signal. The results of the two evaluations are compared to determine a relative phase and/or amplitude at the respective elements.

Abstract: Provided are a method, system, and article of manufacture for a query predicate generator to construct a database query predicate from received query conditions. A plurality of query conditions are received, wherein each query condition includes a comparison operator and a comparison value for a database attribute, and wherein the comparison operator is capable of comprising matching and non-matching operators. The query conditions are processed to determine at least one logical operator to include between the query conditions. A database query predicate is generated to use in a database query to apply against the database comprising the received query conditions chained using the determined logical operators.

Abstract: A thin flat body of clear plastic with a key pad (20) on the inside back base (12), and a chord scale (22) on the outside front of the base (10). The chord scale is fitted with braille nodules (24) for guiding the proper placement of the fingers on the EZ chord. On the bottom or lower side of the base (10) (12) is a gripping angle (14) for the learning chord device. On the top or upper side, and bottom or lower side of the base (10) (12) are gripping angles (14) (16) for the universal chord device. One EZ chord is a device that when manipulated by a human hand, or an artificial hand, is pressed and positioned onto the guitar neck, fret and strings to form and sound guitar chords and/or notes. The EZ chord devices can be used by mentally, physically, or visually handicapped people as well as non-handicapped people, to play and/or learn to play the guitar.

Abstract: Cascaded policing methods and systems are provided which allow lower priority traffic to benefit from otherwise unused capacity allocated to higher priority traffic of a given customer/service with multiple classes of service. The method involves policing packets of a first class in accordance with at least one policing parameter associated with the first class, and policing packets of a second class in accordance with at least one policing parameter associated with the second class in a manner which gives to the second class at least a portion of a traffic throughput afforded to the first class by at least one of said at least one policing parameter, such as a rate guarantee or burst tolerance, associated with the first class of traffic which is not being used by the packets of the first class. The method is easily adapted to an arbitrary number of different traffic classes.

The value is compared to threshold data in order to determine whether repeater attenuation should be incrementally adjusted.

Abstract: An apparatus and method for advancing and/or slowing signatures in a printing press. The apparatus and method includes a series of two or more belt drives, where each belt drive includes at least a pair of opposed belts. The belts are preferably timing or toothed belts driven by sprockets. The sprockets are formed with a semi-elliptical outer surface. As a result, the belts have two directions of motion. The first direction—horizontal—advances the signatures and may be used to slow the signatures. The second direction—vertical—withdraws the belts away from contact with the signatures to prevent buckling or wrinkling during a speed transition or during a transfer between belts. In one embodiment of the present invention, both opposed belts are retracting belts; in another embodiment, one belt is a fixed conveyor belt, while the other opposed belt is a retracting belt.
