Abstract: A material sorting apparatus includes a perforated screen adapted to be moved around an endless track. Devices suck air through the screen inwardly of the track in a predetermined area thereof. A material to be sorted is supplied to the apparatus such that it falls under gravity so that laminar material is selectively sucked towards the surface of the screen. This material is transported in contact with the screen while the screen is moving through and out of the predetermined area but is released from the suction forces when the screen moves out of the predetermined area. A first collection region is located beneath a region adjacent the predetermined region of the track. A second collection region is located adjacent an area of the track to receive material which has been transported in contact with the screen out of the predetermined area of the track.

Abstract: A method for determining probable fail cases of a system includes the steps of: (a) receiving a pattern of input features, each feature representing measurable indicators which themselves are indicative of the condition of the system; (b) providing a set of fail cases, each fail case being represented by an expected pattern of input features, and each fail case being associated with a rule in reverse polish notation which produces a true result if the expected pattern for that rule correlates with a pattern of input features or a false result if the expected pattern for that rule does not correlate with a pattern of input features; and (c) applying the received pattern of input features to each rule to determine whether the received pattern has a true result or a false result for the respective fail case, a true result denoting a probable fail case of the system.

Abstract: A method of securing elongated objects, such as weights or floats to a floating cover. A first step involves providing a sheet form substrate. A second step involves forming elongated retention pockets on the substrate. A third step involves inserting elongated objects into the elongated retention pockets. This method allows thinner lower cost substrates to be used, while still facilitating secure attachment of weights or floats.

Abstract: A method for maintaining the states of a receiver during the silent line state of a network device operating in a low power link suspend mode is presented. Accordingly, a method of freezing the states of the equalizer and keeping the receiver clock locked to a frequency that is approximately equal to that of the input data while providing for rapid adjustment to the phase and thus recovery of the input data is presented. During Silent Line State (SLS), the receiver states are frozen using methods that avoid parasitic decay. Also, the receive clock phase lock loop is locked onto the local transmit clock since the local transmit clock has a frequency approximating the incoming data frequency. During the SLS, the transmitter of the remote network device may have been turned off to conserve power therefore the receiver has no way of immediately knowing the phase of an incoming data.

Abstract: A method and apparatus for handling data during link suspend pulse and the silent line state of a network device operating in a low power link suspend mode is presented. Accordingly, a new generation of network devices capable of operating in both the full power operational mode of prior art network devices, and a low power “link-suspend” operational mode are presented. The low power “link-suspend” (LS) mode reduces the power consumption of a LAN communications link at the physical layer by eliminating the need to continuously transmit standard idles to maintain link between two linked partners. In the LS mode, a low duty cycle “link-suspend-packet” (LSP) is transmitted between periods of silent line state (SLS). During the SLS, which is a non-data transmission period, the transmitter may be turned off to conserve power therefore preventing the receiver from immediately knowing the phase of an incoming data.

Abstract: The invention provides a method for initializing a link suspend device for optimum receive recovery. A method for negotiating link parameters to facilitate rapid recovery of the input data from a silent line state is described.

Abstract: A method and apparatus for transparent implementation of link-suspend capabilities in network devices is presented, which is capable of operating in full or substantially full power operational mode, as well as in a low power “link-suspend” operational mode. The low power “link-suspend” (LS) mode reduces the power consumption of a LAN communications link at the physical layer by eliminating the need to transmit continuous standard idles to maintain link between two linked partners. In the LS mode, a low duty cycle “link-suspend-packet” (LSP) is transmitted between periods of silent line state (SLS). During the SLS, which is a non-data transmission period, the transmitter may be turned off to conserve power. The transmitter power is turned back on when it is time to transmit LSPs or data.

Abstract: A link-suspend operation between network nodes in a point-to-point data communications link is presented. Individual network links will have a full power operational mode for supporting full high-bandwidth communication, and a low power “link-suspend” (LS) operational mode for temporary operation when only limited communication is occurring. The communications link is maintained, while cycling transmitter power on and off during idle periods with a duty cycle that substantially reduces physical layer device (PHY) power, using LSPs. LS mode may be negotiated by advertising capabilities between two network devices. Thus, PHYs at either end of a link can notify the other of the capability to support a LS mode of operation and can negotiate parameters for communications using the LS mode. Further, transmitting and receiving continuous idles, valid data frames, and Wake-on LAN (WOL) packets is supported.
