Title: A method and an arrangement for managing packet queues in switches
Inventor: TUFVESSON PETER
IPC: H04Q11/04
Filed: 2001-04-19
Abstract: The invention relates to a method and means for managing packet queues in switches. The switch has a shared memory split in a small internal memory an d a large external memory. There is limited bandwidth to the external memory. The method comprises the steps of dividing a data stream incoming on the inp ut ports intended for respective output ports into two parts, of which the firs t part is to be sent to an internal queue belonging to at least one output por t and the second part is to be sent to the external memory. The incoming data stream may be identified as belonging to flow groups and the division of the  data stream is then performed e.g. such that flow groups with a higher priority than a division threshold are sent to said internal queues in the first part, while flow groups with priority lower than said threshold are se nt to the external memory in the second part.

Title: Method and apparatus for forming a can end with minimal warping
Inventor: KIRK WILLIAM A
IPC: B21D51/38
Filed: 2001-01-24
Abstract: A method of forming a can end (10) comprises the step of forming a substantially circular metal blank having a periphery and a centre panel (16).  An annular recessed panel (30) is subsequently formed in the blank. The recessed panel has a first depth relative to a substantially annular portion (28) of the blank contiguously formed with the recessed panel. The substantially annular portion of the blank is then coined while the recessed panel is re-formed to a second depth relative to the substantially annular portion of the blank. The second depth is greater than the first depth.  Forming the can end in this manner minimises warping of the can end, and thereby allows the can end to be formed from a relatively thin sheet of metal.

Filed: 2003-01-21
Abstract: A bypass for an exhaust system for a utility vehicle, such as a combine, that, when substantially closed, provides maximum noise attenuation for road transport, i.e., relatively high back pressure, and then, when substantially open, would provide a reduced flow restriction, i.e., relatively low back pressure, for full power, field operation. A bypass flow path in an exhaust pipe is located upstream of a primary muffler. A diaphragm can be provided to manipulate a damper which acts to close the exhaust flow to the primary muffler and open the bypass to an exhaust pipe to effectively bypass the primary muffler.

Title: Smart solid state relay
Inventor: BRYAN LYLE STANLEY
IPC: H01R33/76
Filed: 2003-02-06
Abstract: An electrical system includes a solid state relay (1) and an electrical connector (2) that connects solid state relay (1) to a load (4). The solid state relay (1) includes a power MOSFET (Q1) for switching power to the load (4). A PNP transistor (Q2) monitors the voltage drop across the power MOSFET (Q1), and shuts the power MOSFET off when the voltage drop exceeds a reference level. The solid state relay circuitry floats when the power MOSFET is commanded OFF so there is no leakage to ground. The relay (1) can be used with an electrical connector that includes a short pin (34) or shunt (16) that is disconnected before male and female terminals (12, 22) are unmated. Disconnection of the shunt (16) or the short pin (34) causes the power MOSFET to be commanded OFF so that there is no current flowing through the male and female terminals (12, 22) when they reach an arc susceptible position. The solid state relay (1) and the connector (2) are suitable for use in a 42 Volt automotive electrical system.
