| 20100112965 | Method and Apparatus to Transmit, Receive and Process Signals with Narrow Bandwith Devices - In a representative embodiment, an electronic transmitter comprises a signal source configured to provide an input signal comprising a plurality of frequency components; and a plurality of transducers each configured to receive the input signal and each configured to resonate substantially at one frequency of a subset of the plurality of frequency components. An electronic receiver, an acoustic transmitter and an acoustic receiver are also described. | 05-06-2010 |
| 20100254550 | RECONFIGURABLE ACOUSTIC TRANSDUCER DEVICE - A device comprises: a first acoustic transducer; a second acoustic transducer; one or more transducer drivers; one or more signal receivers; and a transducer configuration device for selectively configuring connections between: (1) at least one of the first and second acoustic transducers; and (2) the one or more transducer drivers and the one or more signal receivers, according to a selected operating mode for the device among a plurality of possible operating modes. | 10-07-2010 |
| 20100327695 | Multi-frequency acoustic array - An apparatus comprises a substrate and transducers disposed over the substrate, each of the transducers comprising a different resonance frequency. A transducer device comprises circuitry configured to transmit signals, or to receive signals, or both. The transducer device also comprises a transducer block comprising a plurality of piezoelectric ultrasonic transducers (PMUT), wherein each of the PMUTs; and an interconnect configured to provide signals from the transducer block to the circuitry and to provide signals from the circuitry to the transducer block. | 12-30-2010 |
| 20110103632 | INTEGRATED ACOUSTIC HORN AND LEAD FRAME - A device for manipulating acoustic signals includes a transducer die and a horn. The transducer die is attached to a lead frame and configured to convert between electrical energy and the acoustic signals, the transducer die having a transducer membrane. The horn is integrally connected with the lead frame, the horn extending from the lead frame and having a throat positioned adjacent to the transducer membrane and a mouth opening at an opposite end of the horn from the throat. | 05-05-2011 |

| 20100050015 | TRIPLE PARITY TECHNIQUE FOR ENABLING EFFICIENT RECOVERY FROM TRIPLE FAILURES IN A STORAGE ARRAY - A method for recovering from three failed data storage devices is disclosed. A plurality of data storage devices hold data, and a row parity storage device holds row parity for them. The data storage devices and the row parity storage device form a set of storage devices. A diagonal parity storage device and an anti-diagonal parity storage device hold parity computed diagonally over the set of storage devices. In the event of a failure of three data storage devices of the set of storage devices, a first failed storage device is chosen for first restoration. A missing block of the first failed storage device is computed by using the remaining set of storage devices, and the diagonal parity storage device, and the anti-diagonal parity storage device. The remaining two failed storage devices are restored by a diagonal parity restoration technique. | 02-25-2010 |
| 20110010599 | N-WAY PARITY TECHNIQUE FOR ENABLING RECOVERY FROM UP TO N STORAGE DEVICE FAILURES - An n-way parity protection technique enables recovery of up to n storage device (e.g., disk) failures in a parity group of a storage array encoded to protect against n-way disk failures. The storage array is created by first configuring the array with m data disks, where m=p−1 and p is a prime number and a row parity disk. n−1 diagonal parity disks are then added to the array. Each diagonal parity set (i.e., diagonal) is associated with a slope that defines the data and row parity blocks of the array that are included in the diagonal. All diagonals having a common slope within a parity group are organized as a diagonal parity class. For each diagonal parity class, a diagonal parity storage disk is provided to store the diagonal parity. | 01-13-2011 |

| 20090247473 | ACYTHIOLS AND COMPONENT THIOL COMPOSITIONS AS ANTI-HIV AND ANTI-RETROVIRAL AGENTS - Certain thiol and acylthiol compounds inhibit retrovirus growth by attacking the highly conserved zinc finger regions of essential viral proteins. These compounds, compositions containing them, and methods of using them to treat retroviral infections such as HIV are described. These compounds are also useful for preparation of vaccines comprised of inactivated retroviruses such as HIV, prevention of the transmission of such retroviruses, and detection of retroviral proteins. | 10-01-2009 |

| 20090125669 | PREVENTING DATA LOSS IN A STORAGE SYSTEM - Storage servers use a fast, non-volatile or persistent memory to store data until it can be written to slower mass storage devices such as disk drives. If the server crashes before a write can complete, the data remains safely stored in non-volatile memory. If the data cannot be committed to disk when the server reboots (e.g. because the destination mass storage device is unavailable), it is stored in a file. When the disk reappears, the data in the file may be used to restore a file or file system on the disk to a consistent state. | 05-14-2009 |
