摘要:
A network device includes at least one network port, a masks table, a rules table, a pointers table, and a fast filter processor. The masks table contains filter information and a mask key. The rules table contains corresponding rules to the filter information and is related to the mask table by the mask key. The pointers table contains boundary data related to the rules for corresponding filter information. The fast filter processor is coupled to the mask table, the rules table and the pointers table, and configured to perform at least one binary search for at least one rule related to a data packet received by the network device at the at least one network port, the binary search being limited based on the boundary data in the pointers table.

A network device including a memory, a queue management unit, a memory management unit, and a search switching unit. The memory includes a plurality of memory banks. The queue management unit is configured to receive a plurality of search requests and to prioritize the search requests. The memory management unit is coupled to the queue management unit and the memory, and is configured to initiate a plurality of binary searches based on the plurality of search requests. Each binary search is executed simultaneously in different banks of the plurality of memory banks. The search switching unit is coupled to the memory and the memory management unit, and is configured to switch each binary search from one memory bank of to another memory bank after a predetermined number of search steps are performed by each binary search.

A network device including at least one network port, a clock, address resolution logic (ARL) tables, and address resolution logic. The clock generates a timing signal. The ARL tables are configured to store and maintain data related to port addresses of the network device. The address resolution logic is coupled to the ARL tables and the clock, and configured to search the ARL tables and to perform learning concurrently during alternating slots of the timing signal. Upon receiving a data packet at the at least one port, the address resolution logic is configured to search the ARL tables for a destination address based on the data packet. When the destination address is found, the address resolution logic is configured to update a related record of the ARL tables based on the learning, the address resolution logic configured to perform searches and updates.

A network device including at least one network port, a clock, address resolution (ARL) tables, and address resolution logic. The at least one network port is configured to send and receive a data packet. The clock is for generating a timing signal. The ARL tables are configured to store and maintain data related to port addresses of the network device. The address resolution logic is coupled to the ARL tables and configured to perform a search and an update to data into the ARL tables based on the data packet, to calculate a current range of the search, to determine an intended result of the update, and to block the update when the intended result will move data out of the current range of the search, the search and the update being performed concurrently during alternating slots of the timing signal.

摘要:
The invention provides a sensor assembly for determining the concentration of hydrogen in an insulating fluid in electric power generation, transmission, and distribution equipment. The assembly includes a housing having an opening therein communicating with the fluid, a hydrogen sensor disposed in the housing and responsive to the concentration of hydrogen in the fluid and generating a signal related to the concentration of hydrogen, and a pressure sensor disposed in the housing responsive to the fluid and generating a second signal indicative of the pressure of the fluid in the equipment. The assembly further includes a signal processor disposed in the housing and connected to the hydrogen sensor and the pressure sensor and responsive to the first and second signals for generating a third signal representing the concentration of hydrogen in the fluid.

The invention provides a housing for a sensor having a semiconductor element for measuring hydrogen concentration in an insulating fluid in electric power generation, transmission, and distribution equipment having a mounting flange on the equipment providing access to the interior of the equipment and provided with a plurality of bolt receiving openings arranged on the mounting flange in a first pattern, which includes a first flange having at least one or more openings for receiving one or more semiconductor hydrogen sensors and an outer periphery, a plurality of bolt receiving apertures arranged in a pattern corresponding to the first pattern within the outer periphery of the first flange, a second flange having a second plurality of bolt receiving apertures arranged in a pattern corresponding to the first pattern within the periphery of the second flange.
摘要:
An ergonomically designed golf club grip including a butt portion which is raised above the axis of the shaft of the club, on the side of the axis closest to the club head toe, to facilitate a proper hand position on the club. The grip is preferably held in the lifeline of the palm of the upper hand, which produces a straighter wrist position and a freer release of the club through the hitting area and follow through.
