| 20110018623 | INTEGRATED CIRCUIT PACKAGE - An integrated circuit combination, comprising first and second integrated circuit dies with respective first and second control register banks, and a path for external control data, within said combination, coupling a first data interface on said first die, which receives the external control data, to the first and second control register banks. | 01-27-2011 |
| 20110022826 | POWER MANAGEMENT APPARATUS AND METHODS - Apparatus and method for power management and especially to power management integrated circuits (PMICs). In one aspect, the invention relates to a PMIC having an internal non-volatile memory (NVM) for storing boot settings for the PMIC. The PMIC also has control circuitry for detecting whether a source of boot settings is available, such as an NVM external to the PMIC, and, if so, using any settings stored in the external source in preference to the relevant settings stored in the internal NVM. The external settings can thus override any internal settings, which is useful for fault diagnosis and/or development. In one aspect the PMIC may have programming circuitry for automatically programming boot settings from an external source into the internal NVM. | 01-27-2011 |
| 20110022859 | POWER MANAGEMENT APPARATUS AND METHODS - Power management integrated circuits (PMICs) and related methods. In one aspect a PMIC which is operable to provide a plurality of PMIC power states is arranged to provide a predetermined delay before a power state transition. The delay is applied after receipt by the PMIC control circuitry of a power state transition command. Applying a delay allows time for the system powered by the PMIC to perform any necessary shut-down procedures and terminate active processes before power is removed, preventing corruption of the system. The delay is preferably configurable. The PMIC may also be arranged to control power converters which are external to the PMIC. In another aspect the PMIC has translation circuitry for providing the control settings of one power block, e.g. power converter, with any necessary modifications to be used by another power block. This means that only one set of control settings needs to be updated to change the output of both power blocks simultaneously. | 01-27-2011 |
| 20110276975 | AUDIO DEVICE - An audio device is provided that is arranged for communication of data and signalling with a controller, signalling from the device to the controller being made in discrete time slots, the device comprising: a plurality of nodes, each assigned a priority value and each having one or more unsolicited response sources capable of generating an unsolicited response for transmission to the controller, wherein unsolicited responses generated from a particular node are assigned the priority value of that node; and unsolicited response management means operable to hold unsolicited responses generated by the plurality of nodes that are awaiting transmission to the controller, wherein when two or more unsolicited responses are awaiting transmission to the controller in the unsolicited response management means, the device is arranged to transmit the unsolicited response with the highest assigned priority value first, in the next free time slot. | 11-10-2011 |

| 20100064347 | METHODS AND SYSTEMS FOR PROTECT AGENTS USING DISTRIBUTED LIGHTWEIGHT FINGERPRINTS - The present invention provides methods and systems to protect an organization's secure information from unauthorized disclosure. The present system uses protect agents installed across various egress points (e.g., email server, user's computer, etc.) to monitor information disclosed by a user. The present system also provides the use of lightweight fingerprint databases (LFD) to maintain a database of fingerprints associated with the organization's secure data. In one embodiment, the LFD is stored locally at the site of each protect agent such that the organization's secure information can be protected even when a protect agent is disconnected from the network. Methods and systems to compress fingerprints to achieve the lightweight fingerprint databases are also provided. In one embodiment, a combined approach, utilizing both the local lightweight fingerprint database and a remote fingerprint server comprising registered fingerprints is used to achieve overall protection of the organization's secure information. | 03-11-2010 |
| 20100064372 | METHODS AND SYSTEMS TO IMPLEMENT FINGERPRINT LOOKUPS ACROSS REMOTE AGENTS - The present invention provides methods and systems to protect an organization's secure information from unauthorized disclosure. The present system uses protect agents installed across various egress points (e.g., email server, user's computer, etc.) to monitor information disclosed by a user. The present system also provides the use of fingerprint servers to remotely maintain a database of fingerprints associated with the organization's secure data. In one embodiment, the protect agents transmit fingerprints associated with the user's information to the fingerprint server utilizing a local network or the public internet. The protect agents then receive a comparison analysis from the fingerprint servers and execute appropriate security action based on the analysis. In one embodiment, a combination of the local network and public internet is utilized to achieve remote agent lookups. | 03-11-2010 |
| 20100124354 | METHODS AND SYSTEMS FOR IMAGE FINGERPRINTING - The present invention provides methods and systems to protect an organization's secure image information from unauthorized disclosure. In one embodiment, methods and systems to generate image fingerprints are provided. The fingerprints are generated for each feature point of an image data. Because the fingerprints take into account the neighborhood features around each feature point, the image fingerprints are robust against derivate images where the original image may have been altered. Methods and systems to maintain a fingerprint database for an organization's secure image data is also provided. In one embodiment, client fingerprints are generated for image data that a user intends to transmit outside of the organization. In some embodiments, suitable security actions are initiated if any of the client fingerprints match any of the fingerprints in the fingerprint database. | 05-20-2010 |
| 20100299727 | METHODS AND SYSTEMS FOR EXACT DATA MATCH FILTERING - A technique for efficiently preventing exact data words (“entities”) from unauthorized disclosure is disclosed. Protect agents installed at various egress points identify candidate entities from digital information desired to be disclosed by a user. The candidate entities are compared against registered entities stored in a lightweight entity database (LWED). If a candidate entity matches against a registered entity in the LWED, the protect agent initiates a security action. Alternately, the protect agent transmits the matching candidate entity to a global entity database (GED) server to receive additional confirmation on whether the candidate entity matches a registered entity. In some instances, the protect agent also receives (from the GED server) metadata information associated with the matching candidate entity. The protect agent utilizes the metadata information to initiate suitable security actions. | 11-25-2010 |
