TeraStor Corporation - San Jose CA

International Classification:

G11B 517

US Classification:

360114, 369 13, 369300

Abstract:

An optical recording head is provided which includes a slider body having a leading edge. A void is formed in the slider body to receive a sphere of optically transparent material. The sphere is inserted into the void such that a portion of the sphere protrudes from the slider body. The protruding portion is lapped to be coplanar with a surface of the slider body to form a near-field lens. A mesa may be formed onto the lapped portion and may include a coil. The slider body, mesa, near-field lens, and coil may be formed in one batch process.

Abstract:

Apparatus for remodeling in the urinary tract of a human female comprising a remodeling device having a shaft with a profile and with proximal and distal extremities. A handle is secured to the proximal extremity of the shaft. A member is mounted on the distal extremity of the shaft. A plurality of needle electrodes are carried by the distal extremity of the shaft and are disposed circumferentially of the shaft. A pusher is carried by the handle for moving the needle electrodes from a retracted position in which they are within the profile of the shaft and an extended position in which they extend sidewise beyond the profile of the shaft. A pump is connected to the handle for supplying a cooling liquid to the distal extremity of the shaft so that it exits from the shaft in the vicinity of the needle electrodes. An RF generator is coupled to the handle and to the needle electrodes for supplying radio frequency energy to the needle electrodes.

US Classification:

716 6, 716 2, 716 3, 716 10, 716 12

Abstract:

Provided are a method, article of manufacture, and apparatus for estimating delays of networks. An automated design system comprises a computer configured to identify a critical path in a network, calculate a delay for the technology-mapped version of the network, calculate a delay for the technology-independent version of the network, calculate a scale factor from the technology-mapped and technology-independent delays, and apply the scale factor to all the delays in the technology-independent network.

International Classification:

G02B 636

US Classification:

385 76, 385 92, 439931

Abstract:

An optical wavelength multiplexer and/or demultiplexer is provided having mechanical strain relief. The mechanical strain relief is provided by mounting ears carried by a molded coupling module supporting the fiber optic cable receptacle. The mounting ears are engaged by a pair of mounting plates carried by a housing for the device. Loads applied to the fiber optic cable receptacle are transferred to the housing frame and do not adversely affect the optical pathway of the assembled device.

International Classification:

US Classification:

359578, 359583, 359589, 359494, 359497

Abstract:

A tunable filter includes a polarizing beam splitter and a half-wave plate that produce two equally polarized beams from an arbitrarily polarized input light. The polarized beams are directed toward a tunable component that consists of an optical substrate coated with a filter and a reflective element on its back and front surface, respectively. The pass and stop beams emerging from the tunable component are retro-reflected by roof structures and passed again through the filter. As a result of this combination of components, the filter's performance is not dependent on polarization and the filter's output channels are not shifted or deviated by tuning.

US Classification:

Abstract:

Embodiments of a computer system, a method, an integrated circuit and a computer-program product (i. e. , software) for use with the computer system are described. These devices and techniques may be used to analyze an electrical characteristic of a logic gate electrically coupled to an output network in a stage. In particular, during the analysis, the effective capacitance of an output network coupled to a logic gate is approximated as a function of a total resistance of the output network, a total capacitance of the output network, and a geometric parameter of the output network. Using the effective capacitance and other parameters, such as a slew rate of an electrical signal applied to an input of the logic gate, an electrical characteristic of the logic gate, such as an input capacitance, is determined.
