A flexible armor system adaptable to a garment suitable for extremity protection uses planar, polygon-shaped solid elements made of ceramic cores wrapped in high strength fabric and arranged with rotable edge and intersection protection as a flexible mosaic array which is bonded between an elastic strike side spall cover and a high tensile strength flexible backer layer, further supported by a substantial fiber pack. A progressive mode of localized system failure during a ballistic strike includes: a projectile penetrating the spall cover, fracturing the ceramic core of a wrapped SE while being partially deformed; the deformed projectile accelerating the fractured but still wrapped solid element before it so as to free the solid element from the array and drive it through the flexible backer as a combined mass at a reduced velocity into the fiber pack.

A golf club head having a striking plate with regions of varying thickness is disclosed herein. A central region has a first thickness range that is thicker than the thickness range of any of the other regions. The thickness of the regions decreases outward from the center. The striking plate may be used on a fairway wood-type golf club head or a driver-type golf club head. The striking plate is preferably composed of steel or titanium.

An actuator includes a motor operated by a controller through a pulse width modulation drive signal applied to a drive circuit that drives the motor. The actuator has an output shaft connected to a coupling structure for manipulating a device such as a variable geometry turbine (VGT) or an exhaust gas recirculation (EGR) valve. The device has a range of motion limited by first and second mechanical stops located at opposing low and high ends of the range. The controller learns the location of the mechanical stops during calibration. An external control unit transmits a desired position to the actuator. A protocol allows the external control unit to implicitly request a positioning mode by virtue of what value range the desired position falls into. The controller is configured to limit the drive signal to a non-harmful level when one of the positioning modes calls for pushing the device against one of the stops.

A gas generator for an air bag having a simple structure, which is activated to apply as small an impact as possible to a vehicle occupant at the initial stage of activation and, thereafter, can reliably protect the vehicle occupant by rapidly increasing gas pressure, is provided. It is a gas generator for an air bag in which an inner cylindrical member is disposed in the housing to define an ignition means accommodating chamber and a combustion chamber, plural flame-transferring holes for communicating the both chambers with each other are formed on the circumferential surface of the inner cylindrical member, and the plural flame-transferring holes are formed at a distance of less than 30% of the axial length of the inner cylindrical member, from an end of the inner cylindrical member. A gas generator, which can use even a gas generating agent with less ignitability, and further can exhibit enough operation performance at the initial stage of activation even when using such a gas generating agent, is provided. It is a gas generator for an air bag in which an inner cylindrical member is disposed in the housing to define an ignition means accommodating chamber and a combustion chamber, and the central angle formed by the adjacent communicating portions which are formed on the circumferential surface of the inner cylindrical member is adjusted to be not more than 60 degrees.

The present invention is directed to implementing theoretical foundations of frequency domain methods aiming to locally decrease the impact of aggregate side lobes of a few discrete frequency tones, in the vicinity of other “victim” frequencies. The family of frequency methods referred to makes use of one or more “canceller tones.” The “canceller tones” loads are optimized to minimize the aggregate power in the neighborhood of the victim frequencies. An exemplary method for decreasing an impact of aggregate side lobes of one or more discrete frequency tones in the vicinity of one or more victim tones comprises the steps of calculating an aggregate power of one or more side lobes of one or more disturber tones within a victim bandwidth; determining at least one optimal load to minimize the aggregate power wherein the at least one optimal load comprises a linear combination of the one or more disturber tones; and applying the at least one optimal load to one or more canceller tones for minimizing the impact of the one or more side lobes of the one or more disturber tones.

Heat treatment equipment and a method of driving the same are provided. The heat treatment equipment includes: a process tube having an aperture at one side thereof; a sealing unit for opening or closing the aperture; and a pressure sensor for measuring sealing pressure between the sealing unit and the one side of the process tube. In the heat treatment equipment, the aperture of the process tube can be sealed according to the sealing pressure of the sealing unit so that the process tube can be precisely sealed.

A protective shell for surrounding a portion of a body of a handheld plasma torch includes a first and second shell section. The plasma torch body includes a handle, a head extending from the handle and a torch tip extending from the head. The first shell section is structurally independent from an outer surface of the plasma torch body. The second shell section is structurally independent from the outer surface of the plasma torch body and is capable of being secured to the first shell section such that, in combination, the first and second shell sections surround the torch head and provide (i) structural protection to the torch head and (ii) thermal insulation to the torch head, wherein the first and second shell sections are electrically insulated relative to the torch head.

A seat including a seat portion, a backrest, and a headrest attached to a structure of the backrest. The headrest includes a head cushion attached to the backrest by at least one headrest arm; the arm is hingedly attached to the backrest structure by a pivot link with a transverse axis; the head cushion is hinged to the arm by a pivot link with a transverse axis. Moreover, the first axis is situated at a rear face of a structural part of the backrest; the second axis is situated close to the bottom edge of the head cushion; in the lowered position, the arm holds the head cushion bearing against the front face of the backrest; in the raised position, the arm holds the head cushion above and in front of the lowered position.

The present invention relates to the problem of estimating the effect of packet transmission impairments, including packet loss, on the subjective quality of a video transmission where frames of data relating to the same video frame or field are permitted to span more than one packet. The invention provides a method of assessing quality of a video signal comprising a sequence of video frames received via a packet switched network using a parameter which is a weighted sum of two counters where the first counter is incremented in dependence of the total number of packets in frames determined to have been received with one or more lost packets and the second counter is incremented in dependence of the number of packets following the first lost packet in each frame and the lost packet itself.
