摘要:
An optical header for coupling an edge emitter light source to an optical fiber is disclosed. The header preferably includes a ceramic or silicon substrate that has a recess for an edge emitting laser. An optical fiber is preferably attached to a substrate and terminates at a light source. The optical fiber is oriented such that the elliptical beam of light produced is situated such that the longer axis of the elliptical beam is orthogonal to the optical fiber. The header is particularly useful when used in conjunction with an optical receiver to form a bidirectional optical transceiver.

A flexible hermetic sealing and method for making the same. Electronic components are coated with an adhesive such as an epoxy, and then a metallic layer consisting of gold, silver, nickel, or another metal is deposited thereon. The metal may be deposited by, for example, any well-known evaporating, sputtering or plating technique. The resultant seal is truly hermetic, and is suitable for use on individual electronic or optical components on a chip.

An apparatus such as a user equipment is in an embodiment of the invention configured to broadcast an access request to at least one neighboring node, the access request containing signature information indicating a user identifier, to check whether a collision indicator is received from a relay node, and to send another access request depending on a received collision indicator. The collision indicator may e.g. be a signature collision indicator, received from the node in case of colliding users, or a collision indicator of transmission received when transmissions of access requests are colliding at the node. A relay node may be configured to receive an access request from a user equipment, to detect a collision, and to inform the user equipment on a detected collision, indicating a type of collision.

Methods, apparatuses, and computer program products for dynamically determining a primary or slave assignment based on an order of cable connection between two devices are provided. Embodiments include detecting, by a first device, insertion of one end of a cable into a port of the first device; determining, by the first device, whether a power signal is received from the cable at the port of the first device; if the power signal is received, performing, by the first device, a data transfer operation over the cable as a slave device to a second device that is coupled to the other end of the cable; and if the power signal is not received, performing, by the first device, a data transfer operation over the cable as a primary device to the second device that is coupled to the other end of the cable.
摘要:
An apparatus for an improved operational amplifier. The disclosed improved operational amplifier comprises an operational amplifier, a first feedback circuit, and one or more secondary feedback circuits. The operational amplifier include a plurality of serially coupled gain stages and is configured so that an output of each gain stage drives an input of a next gain stage and an output of a last gain stage drives a load external to the improved operational amplifier. The first feedback circuit is coupled between an output of a designated gain stage and an output of a previous gain stage to provide a first feedback to the previous gain stage. Each secondary feedback circuit provides an additional feedback to the output of the previous gain stage.
