20100315207 | SENSOR NETWORK MANAGEMENT - Disclosed are methods and apparatuses for managing other apparatuses. In certain aspects, an apparatus for managing other apparatuses includes a processing system configured to receive one or more reports from the other apparatuses, and to send a message to at least one of the other apparatuses, wherein the message instructs the at least one of the other apparatuses to configure at least one parameter that controls when the at least one of the other apparatus sends a report to the apparatus. | 12-16-2010 |
20100315242 | SENSORS IN COMMUNICATION DEVICES - Disclosed are methods and apparatuses for communication. In certain aspects, an apparatus for communication includes one or more sensors configured to measure a condition external to the apparatus, a circuit configured to determine when to transmit data based on the measurement to another apparatus, wherein the determination is based on at least one parameter configurable by the another apparatus, and a transmitter configured to transmit the data. | 12-16-2010 |
20100318641 | SENSOR NETWORK MANAGEMENT - Disclosed are methods and apparatuses for managing reports. In certain aspects, an apparatus for managing reports including a processing system is disclosed. The processing system is configured to receive a plurality of reports from a plurality of other apparatuses, filter out one or more of the plurality of reports, and forward the remaining plurality of reports to another apparatus, wherein each of the plurality of reports comprises data based on a sensor measurement at the respective one of the plurality of other apparatuses. | 12-16-2010 |
20110001484 | SENSOR IN BATTERY - Systems and method for providing sensors in batteries are provided. In certain aspects of the disclosure, a battery comprises a housing dimensioned to fit within a battery compartment of the communication device, a battery cell configured to supply power to the communication device, one or more sensors within the housing configured to measure a condition external to the battery and to received power from the battery cell, and an interface configured to interface the one or more sensors with a processing system in the communication device. | 01-06-2011 |

20100153709 | Trust Establishment From Forward Link Only To Non-Forward Link Only Devices - In the present system three methods are provided for establishing trust between an accessory device and a host device, without placing trust in the device/host owner, so that content protection for subscriber-based mobile broadcast services is provided. That is, a secure link may be established between the accessory device and the host device so when the accessory device receives encrypted content via a forward link only network, the accessory device may decrypt the content at the forward link only stack and then re-encrypt it or re-secure it using the master key or some other derived key based on the master key (or the session key) and then send it to the host device which can decrypt it play it back. | 06-17-2010 |
20100251067 | SYSTEMS AND METHODS FOR PROTECTING A MULTI-PART BROADCAST CONTROL MESSAGE - A method and/or apparatus are provided for protecting control information during broadcasts in a system where primary and second mobile broadcast control messages (PMBCM and SMBCM) are utilized. In order to protect the SMBCM, a first hash information instance is computed based on hashes for each a plurality of control data blocks for the SMBCM. The first hash information instance is appended to the PMBCM. Error-correcting code words are generated for the plurality of hashes for the plurality of control data blocks for the SMBCM. These error-correcting code words are appended to the control data blocks of the SMBCM. A receiver uses the first hash instance information in the PMBCM to determine if any control data blocks of the SMBCM are corrupt. If so, the error-correcting code words may be used to reconstruct the corrupted hash(es) for the control data block(s) in order to authenticate the remaining control data blocks. | 09-30-2010 |
20100306538 | Trust Establishment from Forward Link Only to Non-Forward Link Only Devices - A method, apparatus, and/or system are provided for establishing trust between an accessory device and a host device, using a global key known to both the host device and the accessory device, so that content protection for subscriber-based mobile broadcast services is provided. A secure link may be established between the accessory device and the host device so that when the accessory device receives encrypted content via a secured forward link only network, the accessory device may decrypt the content at the forward link only stack. The content is then re-encrypted/re-secured using one or more derived encryption keys and then sent to the host device where it may be decrypted and played back. A global key, unique to the particular device type of the host device, is employed to ultimately derive the session encryption keys used to re-encrypt/re-secure the content conveyed from the accessory device to the host device. | 12-02-2010 |
