This invention relates to enclosures for microcomputers, and more particularly to such an enclosure which facilitates access to and shielding of the operative components of a personal computer. The enclosure includes a chassis, a cover for cooperating with the chassis for enclosing a volume to contain operating components of the microcomputer, and interrupted wedge members for coupling the chassis and cover upon relative movement therebetween in a predetermined direction. The interrupted wedge members include a plurality of hooks on one of the chassis and cover and a plurality of pockets on the other, with the hooks and pockets being disposed along two sides of the chassis and cover for entry of hooks into cooperating pockets on movement of the cover into position for cooperation with the chassis in enclosing a volume.

In a low profile microcomputer, adapter cards are mounted horizontally in order to be able to use adapter cards designed for earlier, higher, machines. The cards are coupled to the microcomputer planar board by an extender card which extends vertically from the planar and has sockets extending horizontally when the card is in position. The adapter cards have edge connections which couple to these sockets. A removable bridge device is coupled between the top of the extender card and a vertical wall of the microcomputer to minimize horizontal movement of the extender card. For adapter cards which do not extend fully between the front and rear walls of the microcomputer, a channelled support arm, which fits over an end of a card, and is removably mounted on a vertical wall of the computer for slidable engagement with the card.

A grease shield smoke assembly provides smoke to flavor food grilled in a gas grill. The assembly includes a shield having a pair of planar side portions to replace the existing grease shield of the gas grill. Proximal edges of the side portions are coupled together defining an apex of the shield. Distal edges of the side portions relative to the apex are positioned in spaced relationship. Each of a pair of rails is coupled to and extends from an associated one of the side portions. The rails are positioned in alignment extending along the shield between the side portions. A rack is provided having lateral edges. The lateral edges of the rack are supported on the rails wherein the rack is supported between the side portions of the shield. Briquettes to produce smoke may be positioned on the rack.

A method and system for tracking various objects utilizing a plurality of sensors. Separate locations or platforms are provided with a number of sensors collocated with an energy generation/ reflection device, and also a communication device. Each of the platforms is termed local nodes of a multi-sensor fusion system, and possibly can experience relative translational and/or rotational motion in as many as three dimensions with respect to itself and with respect to similar local nodes. Each local node is capable of measuring some combination of bearing angles and/or range and/or respective derivatives from the local node to cooperative local nodes by generating or reflecting energy such that cooperative local nodes may obtain mutual sensor measurements. Information obtained or processed by each local node, including track data or track estimates, are possibly transmitted to one or more central nodes denoted as fusion centers provided with processing capabilities. In addition, when an object or multiple objects which are not local nodes are being tracked, at least one cooperative local node can measure bearing angles and/or range and/or respective derivatives from the local node to the other object. After undergoing a series of processes, sensor data from multiple local nodes are combined at the fusion centers to provide estimates of both the relative geometry and relative orientation of each cooperative local node with respect to other cooperative local nodes and the relative geometry of other sensed objects with respect to each cooperative local node. Estimated relative geometries are either range normalized or scaled with actual ranges depending upon sensor capabilities.
