摘要:
A self-aligned optical coupler, and method of manufacturing thereof, for conducting light from and to vertical and/or horizontal ports on optical devices or optoelectric integrated circuits. The device or circuit having the respective port has keys and/or slots on the device or circuit for self-aligning an end of the optical coupler to the port. The end has corresponding slots and/or keys. Visual alignment marks may be used instead so as to permit automatic alignment with machine vision devices. The coupler may have one or a plurality of waveguides. One of the ends of the coupler may have a connector for a self-aligning optical connection to a connector receptacle of a module or a backplane.

A housing for opto-electronic array devices. The housing includes a base and walls that form a region that receives an opto-electronic semiconductor array. Conductive traces are disposed on a wall such that a front part of the traces are exposed for external electrical connections, while the back part is exposed for internal electrical connections. A transparent substrate having a plurality of micro-lenses cover the base, walls and opto-electronic semiconductor array device. Each micro lens is beneficially made from optical epoxy that is deposited by an ink-jet nozzle. The base and walls are beneficially comprised of a ceramic.

An oil-based mud formation imaging tool for measuring electrical properties of surrounding formation includes at least one base plate, a first port and a second port deployed on the base plate, surface conductors covering both sides of the base plate, and inside conductors deployed in the first port and the second ports and with gaps from the edges of the first and second ports. The first port is fed with electromagnetic signals by a waveguide and a coupling is formed between the imaging tool and the surrounding formation accordingly. Resonance signals are induced at the second port to be used to compute corresponding formation resistivity and dielectric constant. A corresponding imaging method is also provided.

Techniques are provided for a handheld device, such as a smart phone, to obtain device configuration data of a controlled device via machine-readable media, such as a two-dimensional barcode. The device configuration data may be used to allow a user to select one or more features reflected in the device configuration data and supported by the controlled device. The handheld device may obtain device configuration data of multiple controlled devices and, based on the device configuration data, may allow a user to control the multiple controlled devices using the handheld device. In a related technique, a computing device obtains printer driver data of a printing device via machine-readable media. The computing device decodes information encoded in the machine-readable media in order to install a printer driver for the printing device.

According to techniques described herein, print job attributes are checked to identify potential conflicts and potential invalid settings. According to one embodiment of the invention, a job setting manager process executing on a printing device is configured to examine and store print job attributes as detected by print interpreter modules. According to an embodiment of the invention, the job setting manager maintains a data structure comprising print job attributes, their values, and other information. As each interpreter module detects a job setting in the print data, the job setting manager receives this setting and its value and checks the data structure to identify conflicts between previously-set job attributes and whether the requested job attribute is supported by the destination printing device. According to an embodiment of the invention, if a conflict is identified, a notification is produced.

Techniques are provided for testing one or more applications across multiple operating systems (OSs) using virtualization. A device includes a virtualization application and a dispatcher. The virtualization application allows a plurality of guest OSs to execute on a device. The dispatcher is configured to cause a particular file to be stored in a particular location. Each guest OS includes a listener that detects when a file is stored in the particular location. When the listener of each guest OS detects that the particular file is stored in the particular location, the guest OS is configured to perform one or more tasks associated with the particular file. Each guest OS is configured to generate output in response to performing the one or more tasks. The dispatcher is further configured to analyze the output from each of the guest OSs.
摘要:
A PMR writer having a trailing shield structure is disclosed in which a flux choking layer (FCL) formed adjacent to the ABS provides a means to limit the amount of flux flowing from the trailing shield to a first write shield (WS1) near the write pole tip thereby significantly reducing adjacent track erasure. The FCL has a substantially smaller thickness than a top section of the trailing shield to which it is attached along a side opposite the ABS. As a result, pole tip protrusion is reduced compared to prior art PMR writers. The FCL contacts a trailing side of WS1 at the ABS and one or both of the trailing sides of the WS1 and FCL may be tapered or perpendicular with respect to the ABS. The top trailing shield section, FCL, and WS1 may be comprised of NiFe, CoFe, CoFeNi, or alloys thereof.
摘要:
A novel CCP scheme is disclosed for a CPP-GMR sensor in which an amorphous metal/alloy layer such as Hf is inserted between a lower Cu spacer and an oxidizable layer such as Al, Mg, or AlCu prior to performing a pre-ion treatment (PIT) and ion assisted oxidation (IAO) to transform the amorphous layer into a first metal oxide template and the oxidizable layer into a second metal oxide template both having Cu metal paths therein. The amorphous layer promotes smoothness and smaller grain size in the oxidizable layer to minimize variations in the metal paths and thereby improves dR/R, R, and dR uniformity by 50% or more. An amorphous Hf layer may be used without an oxidizable layer, or a thin Cu layer may be inserted in the CCP scheme to form a Hf/PIT/IAO or Hf/Cu/Al/PIT/IAO configuration. A double PIT/IAO process may be used as in Hf/PIT/IAO/Al/PIT/IAO or Hf/PIT/IAO/Hf/PIT/IAO schemes.
