An apparatus and method is provided for facilitating ionization of a gas medium of a laser gyroscope. The apparatus and method employ a solid state light emitting device as a start aid for the laser gyroscope. The solid state light emitting device has a wavelength at or below a threshold wavelength based on a work function of a cathode coating material to prompt ionization of a gas medium within the laser gyroscope.

A side-flexing conveyor chain module includes a first module member having at least two first link ends, a second module member having at least two second link ends, and linkages linking at least one of the first link ends to at least one of the second link ends. Separating the chain module into module members and linking the module members together by linkages distributes the chain tension across the width of the chain module, and thus the hinge pin joining adjacent chain modules.

An apparatus for determining network health, the network comprising a plurality of network base station transceivers in bidirectional communication with radios operating in the network, a first radio transmitting a transmitted signal. The apparatus comprises first and second devices for determining respective first and second signal parameters of respective first and second received signals, the first and second received signals responsive to the transmitted signal transmitted during normal over-the-air operation of the first radio, wherein the received signal received at the first receiver is time aligned with the received signal received at the second receiver to ensure the first and second devices determine the first and second signal parameters of the same transmitted signal and wherein the network health is responsive to the first and second signal parameters.

摘要:
An improved, lower cost method of processing substrates, such as to create solar cells is disclosed. In addition, a modified substrate carrier is disclosed. The carriers typically used to carry the substrates are modified so as to serve as shadow masks for a patterned implant. In some embodiments, various patterns can be created using the carriers such that different process steps can be performed on the substrate by changing the carrier or the position with the carrier. In addition, since the alignment of the substrate to the carrier is critical, the carrier may contain alignment features to insure that the substrate is positioned properly on the carrier. In some embodiments, gravity is used to hold the substrate on the carrier, and therefore, the ions are directed so that the ion beam travels upward toward the bottom side of the carrier.

A guide tube for an ion beam in an ion implanter which is located adjacent a semiconductor wafer being implanted has an outwardly tapering central bore, thereby alleviating problems of beam strike as the ion beam passes through the guide tube.
摘要:
A ring laser gyroscope includes a first plasma shunt arranged to prevent the plasma from contacting a first mirror in the gain region and a second plasma shunt arranged to prevent the plasma from contacting a second mirror in the gain region. The first and second plasma shunts may comprise electrical conductors located in the respective mirror wells and arranged such that contact between the plasma and the electrical conductors quenches the plasma in the mirror wells and produces electrical currents that travels across the mirror wells. The electrical conductors may be formed as metallized strips arranged to extend across the mirror wells, or they may be formed from metal wires. The plasma shunts may alternatively comprise diversion passages formed in the frame and arranged such that the plasma fills the diversion passages and bypasses the mirrors.
