Abstract: A system and method is provided enabling identification of different PN offsets values for CDMA signals without access to a GPS signal, such as when making measurements within indoor environments. When a timing reference, such as that provided by a GPS signal, is lost, the frame boundary timestamp of the CDMA signal itself is used. The parameters of the strongest available PN offset are used. The timing error is determined and the new timing reference timestamp is estimated. The strongest PN is used as the time reference and tau is corrected for. In further embodiments, a user may be able to provide identifying information allowing the estimated timing reference timestamp to be determined even when a GPS signal was never established for providing an initial timing reference.

Abstract: An electronic equipment frame has two side assemblies each formed of two separate configured corner support channel members rigidly connected by welding by a series of cross struts, and rigidly welded to separate top panel and bottom panel assemblies, with each corner support channel member having a deep, flat-bottomed, V-shaped central channel portion where the angled sidewalls extend to the same depth as the outer end walls of the corner support channel member. The respective ends of each corner support channel member also have extension length portions which permit extended length weld areas for rigidly connecting the respective top and bottom panel assemblies thereto.

Abstract: An open frame-type electronic frame in which the two sides are each formed of two separate corrugated channel members rigidly connected by a series of cross struts having specially configured bent tang ends and heavy duty offset weld joints.

Abstract: An electronic component enclosure system with main channel configurations which constitute the four corners and vertical support of a multiple enclosures. The channels are essentially a right angle with a vertex of the angle chamfered, or a right angle of two faces with means for joining the same at the corners, irrespective of whether the means are a sharp bend, a chamfer, and the like. The lateral faces of the channel terminate in recessed gutters. The gutters are essentially a J-shaped reverse bend in most instances. The mating channels are in such a side by side relationship that they require a relatively sharp bend at the right angle of the sections which, in turn, presents a flush surface appearance from the front, and which can be RFI shielded since the vertical channels are all essentially imperforate.

Abstract: The development of a main channel configuration which constitutes the four corners and vertical support of an enclosure is disclosed. The channel is essentially a right angle with the vertex of the angle chamfered which provides additional strength, and a pleasing sturdy aesthetic appearance. The lateral faces of the channel terminate in recessed gutters. The channel itself is symmetrical about a plane extending perpendicular through the chamfered face which connects the two side faces. The enclosure thereafter contemplates eight gussets, four at the top corners and four at the bottom corners. The gussets join cross ties at the two sides, and the front and rear, both top and bottom. Horizontal and vertical unistruts are provided in nestingly overlapped fashion interiorly of the main channels to add additional strength and also to secure the mounting channels which are positioned at various pre-selected locations.

Abstract: A dynamoelectric machine (1), having brushes which contact an armature contact surface such as commutator (6) or slip rings, is provided with a plurality of independent, individually removable brush holders (10, 100). Each brush holder is provided with either a removable pin (102) to allow brushes to contact the armature contact surface after the brush holder (10, 100) has been installed, or with a clamping bolt (40), retaining brushes (8) in a predetermined position for insertion of the brush holder, and removal of the brush holder, the brush holder being tilted or cocked to avoid contact between it and the armature contact surface. Bolting the brush holder (10, 100) into place makes electrical contact between the dynamoelectric machine and the brush holder by means of an insulated, conductive threaded aperture (34) on the exterior service of the machine, a mounting bolt (24) inserted into this aperture (34) urging a conductive portion (20) of the brush holder into electrical contact.
