An apparatus for programming selected entries in an address filter table allows dynamic updating of address registers and eliminates the need to disable unmodified registers in arrangements including multiple registers or entries. The apparatus comprises an interface for receiving data frames from a remote station. A media access controller is provided with an address filter table capable of storing a plurality of entries. Each entry includes an address field for storing a predetermined target address, and an enable field for indicating whether or not the entry is valid. The media access controller is configured to receive each of the data frames from the interface. The media access controller examines the enable field of each entry in the address filter table to determine whether or not the entry is valid. The received data frames are then routed to a destination address based upon the target addresses stored in the address filter table. A device manager may be used for updating the entries in the address filter table.

The invention relates to thermosetting resinous binder compositions comprising a cationic resin (1) and a cross-linking agent (2), wherein the cationic resin (1) is an epoxy resin/amine adduct with on average more than one primary amine group, and the cross-linking agent (2) is a polyketone with on average more than one 1,4-dioxobutylene groups in the backbone. The invention also relates to the preparation of these compositions, and their use in general and in CED more particularly.

A network interface stores data frames between a host computer and a network in a buffer memory. The network interface stores data frames received from the host computer via a peripheral component interconnect (PCI) bus in a transmit buffer for transmission on the network. The network interface also stores data from the network in a receive buffer for transfer to a host computer memory via the PCI bus. A priority control selectively allocates host computer resources based on network transmission and network reception by the network interface, and based on available space in the receive buffer, available data in the transmit buffer, and the estimated length of data packets received from the network. The selective allocation of host computer resources minimizes transmit buffer underflow and receive buffer overflow.

A bipolar electrosurgical forceps for treating tissue includes a pair of opposing first and second jaw members each having a tissue engaging surface disposed thereon. Each of the jaw members is movable relative to one another from a first position to approximate tissue to a second position for engaging tissue therebetween. The first jaw member includes a plurality of ring electrodes disposed thereon having a first electrical potential and the second jaw member includes a corresponding plurality of post electrodes disposed thereon having a second electrical potential. Each of the plurality of post electrodes is inwardly disposed of a respective ring electrode to form an electrode micro-sealing pad wherein upon activation of the forceps tissue grasped between each electrode micro-sealing pad is sealed while tissue adjacent to each electrode micro-sealing pads remains viable.

A data storage and reproduction system is provided using a computer network that comprises a server, at least one attachment unit that is coupled to the server and first and second reproduction devices. The server storing data to be reproduced. At least one attachment unit comprising means for interfacing with a portable memory device having a reference to the reproduction data. The first reproduction device capable of performing a first data reproduction of the reproduction data and the second reproduction device capable of performing a second data reproduction of the reproduction data, the second data reproduction being different than the first data reproduction. Wherein the server responds to a request from the at least one attachment unit by transmitting the reproduction data and where the reproduction data is determined to be a format unsuitable for the reproduction device, the data is reformatted for use by the reproduction device.

A network interface for a workstation having multiple power supply domains includes a wake up module for detecting a wake up request in a received data packet according to the on-now power management scheme and Magic Packet.TM. power management schemes. An EEPROM supplies an override bit to ensure that the on-now power management schemes and Magic Packet.TM. power up management schemes can have co-existent detection mechanisms, independent of whether a required enable bit is set by the operating system. The disclosed arrangement maintains the power management schemes in the event that a power loss disables the enabled bit normally supplied by the host computer operating system.

The present inventive subject matter is drawn to systems and methods of disinfecting and sanitizing the tires and forks of industrial forklifts. In one aspect of this invention, a modular forklift disinfecting system is presented comprising a sanitizing trough designed to allow driving a forklift up a first ramp, into the sanitizing trough containing a sanitizing solution, and out the other end of the sanitizing trough down a second ramp. The system is designed to operate without diverting the forklift from its normal business operation, or utilizing any extra machinery. In another aspect of this invention, a method for disinfecting the tires and forks of industrial forklifts is also presented.

A network interface in a workstation computer includes a pattern matching circuit to enable the workstation computer to wake up to perform prescribed operations requested by a remote workstation. The pattern recognition circuit includes a pattern memory configured for storing a pattern entry for at least a portion of a predetermined pattern. The pattern entry includes a pattern data field and a second field specifying a number of bytes in the input data stream to be ignored prior to comparison with the pattern data field. The pattern matching circuit also includes a comparator for comparing the pattern data field with a selected group of bytes from the data stream. Pattern match logic determines whether the received data packet includes the predetermined pattern based on the comparison result. The second field enables the comparator to selectively ignore a number of bytes in the data stream prior to comparison with a pattern data field, minimizing the amount of null data values that need to be stored in pattern memory. Hence, the second data field enables efficient compression of pattern data in memory.

A network interface for a workstation, configured to be powered down to a standby mode while the network interface remains in a powered-up condition, includes a bypass circuit configured to enable configuration registers in the network interface to complete loading of configuration information in a known state, regardless of an absence of an external data clock from the network during the initialization interval. The bypass circuit ensures that the configuration registers in the network interface that require a network clock (e.g., a transmit clock or a receive clock) are maintained in a known state to enable the network interface to be independently initialized. One example of the bypass circuit holds a power on reset signal until the necessary network clock signal is detected for a predetermined number of detected clock cycles. Another example of the bypass circuit substitutes the absent clock signal with an independent clock source in response to the power on reset signal and holds the power on reset signal for a predetermined number of independent clock cycles, followed by switching back to the signal path providing the required clock signal. The disclosed arrangement enables the network interface device to initialize upon power up and start to monitor network media for wakeup traffic indicating the host computer in the workstation should be activated.
