| 20090070400 | CARRY-SELECT ADDER - A carry select adder to add two binary addends to produce a binary sum. In a first section a first addition block adds 6-bit addend slices having 3-bit lower-half and higher-half slices. A first adder block receives and adds the lower-half slices and outputs an adder-carry-out and a 3-bit lower-half value. A zero-carry-loaded second adder block receives and adds the higher-half slices and outputs a 4-bit zero-related intermediate-value. A one-carry-loaded third adder block receives and adds the higher-half slices and outputs a 4-bit one-related intermediate-value. A 4-bit multiplexer then passes either the zero-related intermediate-value or the one-related intermediate-value as a 1-bit section-carry-out and a 3-bit higher-half value based on the adder-carry-out, wherein the higher-half value and the lower-half value form a 6-bit sum slice corresponding to the 6-bit addend slices. | 03-12-2009 |
| 20090046858 | System and Method of Data Encryption and Data Access of a Set of Storage Devices via a Hardware Key - Systems and methods of storage device data encryption and data access via a hardware key are described here. One embodiment includes a hardware key to intercept a request sent from a host to a storage device to access data stored on one of a set of storage devices, wherein the data stored on the storage device has been encrypted. The hardware key is configured to be plugged into a port of the host and comprising a unit to control data access to the set of storage devices. The hardware key is to interpret the request and issue a command to the one of the set of storage devices, to access the encrypted data. The hardware key is to provide an encryption key to decipher the encrypted data from the one of the set of storage devices. | 02-19-2009 |
| 20090044284 | System and Method of Generating and Providing a Set of Randomly Selected Substitute Characters in Place of a User Entered Key Phrase - Systems and methods of generating and providing a set of randomly selected substitute characters in place of a user entered key phrase are described here. One embodiment includes receiving a key phrase input by a user to gain access to secured data, and, in response to receiving the user entered key phrase, randomly selecting a set of substitute characters and providing the set of substitute characters in place of the key phrase entered by the user. In one embodiment, the randomly selecting comprises using a random number generator to select from a substitute character from a pre-generated set of substitute characters for each character, number, or text of the user entered key phrase. In one embodiment, the providing the set of substitute characters further comprises providing the randomly selected set of substitute characters in a display buffer as the user entered key phrase. | 02-12-2009 |
| 20090044282 | System and Method for Generating and Displaying a Keyboard Comprising a Random Layout of Keys - Systems and methods for generating and displaying a keyboard comprising a random layout of keys are described here. One embodiment includes displaying a keyboard comprising a random layout of keys, to receive a user entered key phrase to be entered to gain access to secure data, and receiving the user entered key phrase by the user selecting keys of the keyboard via a pointing input device. The displaying includes, individually mapping keys of the keyboard to a separate value within a first value range, selecting a key for the keyboard based on the random value generated, and repeating the generating the random value and selecting a key for the keyboard based on the random value to select a remainder of keys for generating the random layout of keys for the keyboard. | 02-12-2009 |
| 20080288782 | Method and Apparatus of Providing Security to an External Attachment Device - Systems and methods of providing security to an external Serial Advanced Technology Attachment (SATA) device are described herein. One embodiment includes presenting to a computing device, a first partition of an external Serial Advanced Technology Attachment storage device, as a Read Only Memory; restricting the computing device from accessing a secured second partition of the external Serial Advanced Technology Attachment storage device; and in response to receiving a valid identity authentication, unrestricting access to the second partition of the external Serial Advanced Technology Attachment storage device. In one embodiment, in response to receiving a logon request from the computing device, an identity authentication process is initiated, wherein the process is stored on the first partition. Furthermore, in one embodiment, a process stored on a disk controller receives an encryption key from the process stored on the first partition of the Serial Advanced Technology Attachment storage device, and the process stored on the disk controller uses the encryption key to decrypt the second partition of the Serial Advanced Technology Attachment storage device. | 11-20-2008 |
| 20080288703 | Method and Apparatus of Providing Power to an External Attachment Device via a Computing Device - A method and apparatus of providing power to an external Serial Advanced Technology Attachment (SATA) device via a computing device are described here. One embodiment includes, transmitting data to a plurality of devices via at least one port of a first type of a computing device, and providing power to the plurality of devices via at least one port of a second type of the computing device; wherein the plurality of devices comprises one or more of a disk controller and an external Serial Advanced Technology Attachment device. The at least one port of the first type of the computing device is an external Serial Advanced Technology Attachment port and the at least one port of the second type of the computing device is a Universal Serial Bus port. In one embodiment, the disk controller comprises at least one parallel advanced technology attachment port. | 11-20-2008 |
| 20080270751 | SYSTEM AND METHOD FOR PROCESSING DATA IN A PIPELINE OF COMPUTERS - A series of computers to process data including a first and a last computer. Each of the computers except the first is preceded by a prior computer and each except the last is followed by a subsequent computer. A logic reads new data via a first data path and a logic writes old data via a second data path. A logic process the new data to produce the old data and, except for the last computer, a storage element stores the old data. The logic to write operates after the logic to read and the logic to write operates before the logic to process. | 10-30-2008 |

| 20080250092 | SYSTEM FOR CONVOLUTION CALCULATION WITH MULTIPLE COMPUTER PROCESSORS - A system for calculating a convolution of a data function with a filter function utilizing an array of processors including first and last processors. A coefficient value based on a derivation of the filter function and a data value representative of the data function are multiplied to produce a current intermediate value. Except in the first processor, a prior intermediate value is then added to the current intermediate value. Except in the last processor, the data and current intermediate values are then sent to the next processor. Then the last processor's prior intermediate value, if any, is added to its current intermediate value to produce a result value, wherein the result values collectively are representative of the convolution of the data function with the filter function. | 10-09-2008 |
