摘要： Protection from current and voltage spikes is provided for a laser array by attaching a reverse diode laser array to shared contact pads before the first laser array is bonded to those pads. The arrangement provides for surge protection even during fabrication of the laser package where device failure results from power surges before surge protection circuitry is in place. Surge protection is afforded by having a reverse diode of the reverse diode array electrically in parallel with a corresponding laser diode of the protected array when activated.

摘要： A technique for blind channel estimation is disclosed herein. A read value that is read from a multi-level storage device is received, as are a set of bins having bin ranges and (for each of the bins in the set) a corresponding portion of read values which fall into that particular bin. One or more of the bin ranges is adjusted such that the received portions of read values remain substantially the same after adjustment and after assignment of the read value to one of the set of bins after adjustment.

摘要： A re-configurable RF architecture includes both a 2×2 MIMO mode and a 1×2 MIMO mode. The 2×2 MIMO mode includes a first RF chain coupled with a first dual band antenna and configured to both transmit (Tx) and receive (Rx) using two different RF protocols. The 2×2 MIMO mode also includes a second RF chain coupled with a second dual band antenna and configured to both Tx and Rx using a single RF protocol. The first RF chain may be coupled with a third antenna configured for near field proximity sensing. The RF architecture is reversibly switchable from the 2×2 MIMO mode to the 1×2 MIMO mode when near field proximity detection is required. In the 1×2 MIMO mode the Tx/Rx capabilities of the second chain using the second dual band antenna are retained and the first chain is configured for Rx only capability using the third antenna.
摘要翻译：可重配置的RF架构包括2×2 MIMO模式和1×2 MIMO模式。 2×2 MIMO模式包括与第一双频带天线耦合的第一RF链，并且被配置为使用两个不同RF协议来发送（Tx）和接收（Rx）。 2×2 MIMO模式还包括与第二双频带天线耦合的第二RF链，并且使用单个RF协议来配置为Tx和Rx两者。第一RF链可以与配置用于近场接近感测的第三天线耦合。当需要近场接近检测时，RF架构可以从2×2 MIMO模式可逆地切换到1×2 MIMO模式。在1×2 MIMO模式中，使用第二双频带天线的第二链的Tx / Rx能力被保留，并且第一链被配置用于仅使用第三天线的Rx功能。

摘要： A read value that is read from a multi-level storage device is received, as are a set of bins having bin ranges. A set of amounts corresponding to the set of bins is received where each amount in the set indicates an amount of read values which fall into the corresponding bin. One or more of the bin ranges is adjusted, including by: in the event there is a first bin range that is less than the received read value, increasing at least the first bin range and in the event there is a second bin range that is greater than the received read value, decreasing at least the second bin range.

摘要： Data is stored from a host. A flash memory is divided into a plurality of memory groups, the memory groups each comprising a plurality of flash memory blocks. A first portion of one of the plurality of memory groups is allocated for storing parity data of an error-correcting code for the memory group. A second portion of the memory group is allocated for storing data from the host. A flash memory block in the memory group is erased prior to writing the data from the host, wherein the flash memory block contains valid data. The erased valid data is recovered using the error-correcting code.

摘要： A laser package includes a housing and a subassembly to which the critical components of the laser package are mounted. The subassembly is structured to preserve component alignment even in the presence of thermal excursions by ensuring that any movement which might occur effects all the components in a way to preserve alignment. The subassembly is easily removable from the housing and thus permits replacement if a failure should occur. A reverse diode is included to provide a path for reverse currents which otherwise would be damaging to the active laser diode.
