Abstract: A system and method to measure channel quality in terms of signal to noise ratio for the transmission of coded signals over fading channels. A Viterbi decoder metric for the Maximum Likelihood path is used as a channel quality measure. This Euclidean distance metric is filtered in order to smooth out short term variations. The filtered or averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes and at different mobile speeds. The filtered metric is mapped to the signal to noise ratio per symbol using a threshold based scheme. Use of this implicit signal to noise ratio estimate is used for the mobile assisted handoff and data rate adaptation in the transmitter.

Abstract: Described here, is a method for obtaining high-resolution snap-shot images of moving objects in MR imaging applications through the elimination of ghosting and other image artifacts by estimating motion frequency data, estimating amplitude data for the motion frequency data, interpolating the motion frequency data and the amplitude data to generate snap-shot data frames, and generating snapshot images of each data frame.

Abstract: In an oil cooled alternator (10) having a plurality of commonly connected, relatively inflexible stator coils (14) with distal ends (16) for providing electrical output power from the alternator (10), the improvement being a terminal assembly (18) for making electrical connection with each of said distal ends (16) which flexible conductor (20) with a pair of ends (22) on opposite sides of an elongate body having a flexibility substantially greater than that of coils (14) and a connector (24) with a first relatively rigid portion adapted for attachment to distal end (16) of coil (14) and second portion (28) adapted for fixed electrical connection with one of pair of ends (22) of flexible conductor (20) and relatively rigid post assembly (30) having elongate body portion (32) extending between two ends (34) and having assembly 36 carried at one of said two ends (34) for electrical connection with the other of the pair of ends (22) of flexible conductor (20).

Abstract: A ballistic resistant protective garment of multi-component construction for covering and protecting vital portions of the body of the wearer. The garment having layers of composite body armor material which are positioned generally at the strike face portion of the garment. Each layer of the composite body armor material is formed of resin plies having high tensile strength fibers disposed therein. The high tensile strength fibers of one ply are placed in a transverse direction to the high tensile strength fibers of an adjacent ply and a laminate film covers the sub-layer plies enclosing them and sandwiching them together to form a single layer of the composite material. The combined multicomponent construction of the overlying layers formed of laminated plies of aramid and resin with the woven flexible panels of high tensile strength fiber sheets together create a multi-component thin and lightweight ballistic resistant body armor pad.

Abstract: A ballistic resistant garment, having a top end and bottom end, for covering and protecting vital portions of a human body, which includes at least two panels having at least a first panel and a second panel which are adjacent and overlie one another in which each of the panels is constructed of a plurality of at least two layers of ballistic resistant material. The protective garment also includes a multiplicity of multi-panel securement stitches disposed in a row through the panels connecting the panels together in which the row is positioned in a direction angularly displaced from a substantially vertical direction determined generally between the top and bottom ends of the protective garment.

Abstract: A power rotary hand saw (10) with a blade guard 36 mounted for powered movement between a guarding position (FIG. 1) and a nonguarding position (FIG. 2) is moved to the guarding position (FIG. 1) by a separate dedicated electrical motor (46) rotating a drive gear (42) linked with an elongate set of gear teeth (40) and returned when electrical power to the guard drive motor (46) is reversed by a guard control switch (49) separate and apart from a blade drive motor control trigger switch (34). Alternatively, power to the guard drive motor (46) is removed and a coil bias spring (52) return the guard (36) to the guarding position (FIG. 1). The guard driving mechanism (42, 44, 46) is mounted for movement between a drive position (FIG. 1) in which the drive mechanism is linked to the set of gear teeth (40) and a nondrive position in which the drive gear (42) is spaced from linkage with the set of gear teeth (40) and is disabled from responding to actuation of the guard drive power control switch (49).

Abstract: A protective garment for covering a frontal chest, waist and groin areas of a wearer which includes, a panel constructed of a plurality of sheets in which each sheet is constructed of flexible woven high strength protective fibers and in which the panel is formed for underlying clothing which covers the frontal waist area of the wearer and in which the panel extends continuously to overlie the frontal chest area down to and over the frontal waist and groin areas of the wearer. Various straps are used for releasably securing the panel to and maintaining the panel in a position overlying the frontal chest, waist and groin areas of the wearer.

Abstract: A puncture resistant garment (20) which includes a plurality of flexible layers of woven sheets (22) positioned to overlie one another forming a puncture resistant panel (28), in which each of the plurality of woven sheets (22) is constructed of aramid fiber (24) and in which the woven sheets (22) have a weave of at least 60 said aramid fibers per inch in one direction and at least 60 said aramid fibers per inch in another direction transverse to the one direction. The aramid fiber (24) has at least one of the following characteristics of: a) the aramid fibers are constructed of filaments which provide from 50,000,000 up to 90,000,000 filament crossovers per square inch in each of the plurality of woven sheets (22), b) the aramid fibers provide greater than 3 percent of break elongation and c) the aramid fiber provides greater than 23.

Abstract: A funnel (22) includes a liner (28) connected to a support structure (26). The funnel (22) is connected to a base (24) positioned within a trash bag (78) having an opening disposed around the support structure (26) at a discharge opening of the funnel (26). The liner (22) is detachable from the support structure (26) which is compressed for storage after being detached from the base (24). The liner (22) and base (24) are connected to the support structure (26) for storage. The components are packaged as a kit with adhesive so a purchaser can assemble the components.
