  • Patent number: 10060067
    Abstract: Systems and methods for determining an out of balance condition of a washing machine are provided. In particular, a plurality of angular positions of a motor associated with a washing machine can be determined. The washing machine can include a wash tub, and a wash basket rotatably mounted within the wash tub. The motor is configured to rotate the wash basket within said wash tub. Data indicative of at least a single phase of motor current being applied to the motor can be obtained while the wash basket rotates. The data can be spatially sampled over at least a subset of the plurality of angular positions of the motor. An out of balance condition associated with the washing machine can be determined based at least in part on the sampled data.

  • Patent number: 9824710
    Abstract: A heat-assisted magnetic recording (HAMR) medium has a multilayered or laminated heat-sink structure. The laminated heat-sink structure includes a first heat-sink layer and a RuAl—X thermal barrier layer between the medium substrate and the first heat-sink layer. The laminated heat-sink structure may include a second heat-sink layer may between the substrate and the RuAl—X thermal barrier layer. In the RuAl—X thermal barrier layer, X is selected from C and one or more oxides of Si, Ti, W, Zr and Hf. The HAMR medium with the laminated heat-sink structure reduces the amount of required laser current as compared to a similar HAMR medium with a conventional single heat-sink layer of the same thickness, while also slightly improving magnetic properties and recording performance.

  • Patent number: 9158683
    Abstract: A multiport memory emulator receives first and a second memory commands for concurrent processing of memory commands in one operation clock cycle. Data operands are stored in a memory array of bitcells that is arranged as rows and memory banks. An auxiliary memory bank provides a bitcell for physically storing an additional word for each row. The bank address portion of each of the first and second memory commands is respectively translated into a first and second physical bank address. The second physical bank address is assigned a bank address of a bank that is currently unused in response to a determination that the bank address portions are equal and the bank associated with the first bank address is designated as a currently unused bank for subsequently received memory commands in response to the determination that the bank address portions are equal. Simultaneous read and write operations are possible.
