A system and method for a row forwarding of pixel data in a 3-D graphics pipeline. Specifically, in one embodiment a data write unit capable of row forwarding in a graphics pipeline includes a first memory and logic. The first memory stores a plurality of rows of pixel information associated with a pixel. The plurality of rows of pixel information includes data related to surface characteristics of the pixel and includes a first row, e.g., a front row, and a second row, e.g., a rear row. A data write unit includes first logic for accessing a portion of the second row and for storing data accessed therein into a portion of the first row. The data write unit also comprises logic for recirculating the plurality of rows of pixel information to an upstream pipeline module for further processing thereof.

Precision navigation within a theater of operations is performed by receiving, at each of a plurality of spaced apart known locations, GPS satellite signals from a plurality of GPS satellites, wherein the known locations approximately define the theater of operations. A measure of error in the GPS satellite signal for each of the plurality of GPS satellites is determined. The measures of error in the GPS satellite signals are utilized to correct GPS satellite signals received at an unknown location within the theater of operations. The corrected GPS satellite signals are then used to determine a precise position of the unknown location within the theater of operations.

A tail cap assembly for a light beam generator includes a jack, while a remote switch connected by a cable to a plug is removably connectable to the tail cap jack. The tail cap assembly may also include a pushbutton switch. A remote tape switch may be contained in a flexible housing that is removably securable to a rail of a rail mount structure secured to a firearm.

A flashlight has a lamp assembly with a number of different output states. The flashlight has an elongated housing defining a housing axis, and a control ring encompasses the housing and rotates on the housing axis. The control ring operates to change the output state in response to rotation of the element. A detent mechanism operably connects the control ring to the housing. The detent mechanism provides a number of different stable positions of the control ring with respect to the housing, and may provide a low profile by employing a thin sheet or wire spring compressing in an axial direction.

A vacuum box having features ideal for utilization with an overlock sewing machine housed in a flat-bed table in a garment factory setting. The vacuum flat-bed table of an overlock sewing machine. The vacuum box is a receptacle having bottom, top, left, right, front, and rear walls. A portion of the front wall can have an opening covered by a hingably mounted door panel. The receptacle has a first compartment and a second compartment. The first compartment is sealed-off from the first compartment and has a electric outlet placed therein placed along the left or right wall. A suction fan is located in the second compartment. A horizontally sliding top panel is placed above the top surface of the top wall. The top panel is pivotally connected to guide slots placed along the front and back wall of the receptacle in a manner which allows the top panel to be extended horizontally to increase the top surface and drawn in to reduce the top surface. The vacuum box of the present invention uses dual flexible vacuum hoses for maximal suction effect. A first vacuum hose and a second vacuum hose each connects at its first end to the receptacle and extends into the second compartment. Each vacuum hose connects at a second end to predetermined point on the sewing machine.

Methods and systems are provided for steering network packets. According to one embodiment, a dynamically configurable steering table is stored within a memory of each network interface of a networking routing/switching device. The steering table represents a mapping that logically assigns each of the network interfaces to one of multiple packet processing resources of the network routing/switching device. The steering table has contained therein information indicative of a unique identifier/address of the assigned packet processing resource. Responsive to receiving a packet on a network interface, the network interface performs Layer 1 or Layer 2 steering of the received packet to the assigned packet processing resource by retrieving the information indicative of the unique identifier/address of the assigned packet processing resource from the steering table based on a channel identifier associated with the received packet and the received packet is processed by the assigned packet processing resource.

A network device that includes a first memory to store packets in segments; a second memory to store pointers associated with the first memory; a third memory to store summary bits and allocation bits, where the allocation bits correspond to the segments. The network device also includes a processor to receive a request for memory resources; determine whether a pointer is stored in the second memory, where the pointer corresponds to a segment that is available to store a packet; and send the pointer when the pointer is stored in the second memory. The processor is further to perform a search to identify other pointers when the pointer is not stored in the second memory, where performing the search includes identifying a set of allocation bits, based on an unallocated summary bit, that corresponds to the other pointers; identify another pointer, of the other pointers, based on an unallocated allocation bit of the set of allocation bits; and send the other pointer in response to the request.
