Apparatus and methods consistent with the present invention provide for processing mailpiece information in an identification code sorting system by an identification code server. In one embodiment, a primary identification code server receives an identification file containing identification information uniquely corresponding to a mailpiece. In this embodiment, the primary identification code server processes the mailpiece information and may send the identification file to a secondary identification code server. In another embodiment, a secondary identification code server receives an identification file from a primary identification code server and processes the mailpiece information.

A display system and method for an aircraft simultaneously displays the terrain under the flight plan, or under the current track of the aircraft, as both a two-dimensional lateral situation view image and as a perspective vertical situation view image. This provides improved tactical flight planning, and that does not erroneously show the flight plan passing through the displayed terrain.

Apparatus and methods consistent with the present invention provide for processing delivery item information in an identification code sorting system by an identification code server. In one embodiment, a primary identification code server receives an identification file containing identification information uniquely corresponding to a delivery item. In this embodiment, the primary identification code server processes the delivery item information and may send the identification file to a secondary identification code server. In another embodiment, a secondary identification code server receives an identification file from a primary identification code server and processes the delivery item information.
摘要:
A method for forming a plurality of parallel metal lines on a substrate of thin film elastomeric material and a wire grid polarizer formed by such method. A sacrificial layer is formed by coating the substrate with a water soluble polymer while the substrate is stretched. The existing tensile force is removed, leaving an undulating topology of buckled sacrificial layer material. A masking layer is then deposited at an oblique angle and then fractured into parallel lines of material by application of a second tensile force. Unmasked portions of the sacrificial layer are removed by dry etch. A metallic layer is then deposited and a lift off process employed to remove remaining portions of the sacrificial layer and materials deposited thereover. Upon removal of the second tensile force, the substrate returns to its unstressed length with metal lines of predetermined periodicity thereon.

The present invention relates to an improved railway frog having opposite side flangeways, each flangeway comprising a channel with an ending width greater than a corresponding channel width of a conventional frog. The improved frog further comprising a segment with an outside wall angle greater than a corresponding segment wall angle of a conventional frog.

A method and apparatus to independently control the closing or making of contactors in a modular contactor assembly is disclosed. The apparatus includes a contactor assembly having multiple contactors such that each contactor is separately controlled such that one contactor may be closed without the other contactors of the assembly being closed. The contactors are arranged such that a pair of contactors is caused to close following a zero-voltage crossing of a power signal. A third contactor is caused to close after the pair of contactors has closed.

A modular asynchronous contactor assembly includes a contactor for each phase or pole of an electrical device. The contactor assembly is applicable as both a switching device and an isolation or load protection device. As such, each contactor is constructed so that each includes multiple contact assemblies. Moreover, the contactors within a single contactor assembly or housing can be independently controlled so that the contacts of one contactor can be opened without opening the contacts of the other contactors of the contactor assembly.

Control of an induction motor is carried out to limit damaging arcing stress and mechanical stresses placed on the control contactor assembly and the induction motor resulting from the simultaneous or synchronous breaking and making of contactors employed to connect the windings of the motor to a power supply. Asynchronously connecting the windings to the power supply via the asynchronous or non-simultaneous closing of the contactors of a modular contactor assembly reduces the potentially damaging transient current, the associated torque oscillations, and mechanical stresses. The present invention is particularly applicable to delta motors that are started with its windings in a star or wye configuration followed by the reconnection of the windings in a delta configuration when the motor is at normal running speed.

The present invention provides a compliant mechanism that can be used to make a variety of devices, such as tunable optical devices, that are more reliable, more cost effective, and/or exhibit better performance than prior art devices. In one embodiment, the complaint mechanism includes an island that is suspended from a frame using a compliant member that is attached to the frame and the island. Individual actuators and/or sensor elements may be placed on the island, so that each island may be individually actuated or sensed.
