摘要:
Methods and systems may provide an alignment scheme for components that may reduce positional deviation between the components. The method may include placing a first component on top of a substrate, wherein the first component includes a receiving alignment feature, and coupling a second component to the first component, wherein the coupling includes inserting a protruding alignment feature of the second component into the receiving alignment feature of the first component. In one example, the first component includes an edge-emitting semiconductor die and the second component include one or more of an optical lens and an alignment frame.

There is provided a first dock for a portable hard disk, where the first dock is connectable to a host device. There is also provided a corresponding method for accessing content on the host device during use of the dock. It is advantageous that the host device is able to access content from portable hard disks that are docked with the first dock and a second dock.

A system and method for complete message delivery to a multi-mode communication device is presented. The communication device is adaptable to communicate with one or more carrier networks and one or more data networks. When a new message is received for the communication device, a message notification is sent to the device via a first network. The communication device parses the message notification and retrieves the complete message via a second network. Alternatively, the message notification may be delivered and the complete message may be retrieved via the same network.

Prepare an alkenyl-aromatic foam having good surface quality, high thermal insulating properties and low density using an extrusion method by expanding a foamable polymer composition of an alkenyl-aromatic polymer composition containing less than 20 weight-percent covalently bonded halogens and having a polydispersity of less than 2.5 and a water solubility greater than 0.09 moles per kilogram and 2.2 moles per kilogram or less at 130 degrees Celsius and 101 kilopascals pressure and 0.8-2 moles per kilogram of a blowing agent containing 0.4 moles per kilogram or more of a chlorine-free fluorinated blowing agents and water at a concentration of at least 0.22 moles per kilogram; wherein moles per kilogram are relative to kilograms of alkenyl-aromatic polymer. The resulting foam has a density of 64 kilograms per cubic meter or less and a thermal conductivity of 32 milliwatts per meter-Kelvin or less after 180 days.

Embodiments introduce redundant optical channels to significantly extend the lifetime of parallel optical transceivers. A plurality of transmitters, N, transmit on a plurality of optical channels, where N is an integer number of optical channels greater than 1. One or more redundant channels, M, are also provided. N+M multiple input shift registers provide multiple paths for signals from each of the transmitters to connect to N+M laser diodes. In the event up to M of the N+M laser diodes fail, the multiple input shift registers connect the N transmitters to functioning ones of the N+M laser diodes thus extending the life of the device. A corresponding scheme is also described for the receiver side.
