| 20100270105 | Climbing Apparatus - Disclosed is a durable, lightweight, nonslip, camouflage, structurally superior climbing treestand that is inexpensive and simple to manufacture, may be easily compacted for transportation, and includes one or more of arm/weapon rests, interchangeable grips, tactile and visual indicators, safety harnesses, nonslip, adjustable belts, and receptacles for bumpers, sockets, and the like. Also disclosed is a parabolic belt capable of firmly gripping a tree trunk to prevent slippage when used in conjunction with interchangeable or permanent platform grips. Tactile and visual indicators allow a user to ensure that the belt is optimally installed even in conditions in which the user may not view such indicators. Bumpers and safety harnesses are incorporated to prevent falls from heights through trees, tree limbs, and the like. Interchangeable sockets allow the user to customize the treestand to meet the user's needs (e.g., photography, hunting, snacking, etc.). | 10-28-2010 |

| 20080232583 | Vehicle Segment Certificate Management Using Shared Certificate Schemes - The present invention advantageously provides techniques to solve problems with combinatorial anonymous certificate management by addressing critical issues concerning its feasibility, scalability, and performance. Methods and procedures to manage IEEE 1609.2 anonymous and identifying cryptographic keys and certificates in the Vehicle Infrastructure Integration (VII) system are presented, along with methods for management of identifying and anonymous certificates in a partitioned Certificate Authority architecture designed to enhance vehicle privacy. Novel methods for vehicles to dynamically change an anonymous certificate for use while maintaining vehicle privacy are given. Refinements to basic combinatorial schemes are presented including probabilistic key replacement, rekey counter decrement, dynamic rekey threshold, geographic attack isolation and proofs of geographic position. | 09-25-2008 |
| 20080232595 | Vehicle Segment Certificate Management Using Short-Lived, Unlinked Certificate Schemes - The present invention advantageously provides a system and method for management of cryptographic keys and certificates for a plurality of vehicles. Each vehicle of the plurality of vehicles generates public/private key pairs, requests multiple time-distributed certificates, creates an encrypted identity, and surrenders expired certificates. An assigning authority receives the public/private key pairs, the request for multiple time-distributed certificates, the encrypted identity, and the expired certificates from said vehicle. The assigning authority authorizes the vehicle with an authorizing authority, validates the expired certificates, proves ownership, and distributes the requested time-distributed certificates to said vehicle. Validation can comprise checking expired certificates against misused, compromised and/or previously surrendered certificates. Time-distributed certificates can have lifetimes adjustable based on certificate misuse detection system algorithms, amount of malicious activity detected, and/or certificate authority capacity. | 09-25-2008 |
| 20100031025 | Method and system to authorize and assign digital certificates without loss of privacy, and/or to enhance privacy key selection - A method and system for public key infrastructure key and certificate management provides anonymity to certificate holders and protects the privacy of certificate holders from the compromise of a certificate authority. Functional separation is provided in the authorization of a certificate request and the assignment of certificates and key pairs. The authorizing certificate authority approves or denies each certificate request from a requestor whose identity is not made available to the assigning certificate authority. The assigning certificate authority, upon approval from the authorizing certificate authority, issues one or more certificates and optionally generates and provides the associated key pairs to the requester without disclosing these certificates and key pairs to the authorizing certificate authority. In another aspect, a distributed method is disclosed that allows individual nodes and/or units in a network to select certificates for broadcasting messages to a community of interest with a non-unique key. | 02-04-2010 |
| 20100031042 | Method and System for Secure Session Establishment Using Identity-Based Encryption (VDTLS) - The inventive system for providing strong security for UDP communications in networks comprises a server, a client, and a secure communication protocol wherein authentication of client and server, either unilaterally or mutually, is performed using identity based encryption, the secure communication protocol preserves privacy of the client, achieves significant bandwidth savings, and eliminates overheads associated with certificate management. VDTLS also enables session mobility across multiple IP domains through its session resumption capability. | 02-04-2010 |
| 20100037057 | SYSTEM AND METHOD FOR USING NETWORKED MOBILE DEVICES IN VEHICLES - A system and method for using networked mobile devices in a vehicle in a tightly integrated manner is presented. The vehicle has an OBE, a mobile device client, and vehicle components, and the mobile device has a mobile device proxy and applications, such that the mobile device client and the mobile device proxy communicate, enabling dynamic transfer of the applications to the OBE and execution of the applications on the mobile device and the OBE using the plurality of vehicle components at runtime. In one embodiment, the mobile device client and the mobile device proxy authenticate each other. The authentication can be performed using digital certificates. The mobile device client can communicate the vehicle components on the vehicle to the mobile device proxy. The mobile device client and the mobile device proxy can communicate using Bluetooth. The vehicle components can include dashboard displays, speakers, and voice I/O systems. | 02-11-2010 |
| 20100262641 | Method and System for Estimating and Applying a Step Size Value for LMS Echo Cancellers - Disclosed is an improved method and apparatus for estimating and applying a step size value for a least mean squares echo canceller. A power estimate of an excitation signal is compared to a reference power level to determine a shift adjustment. The shift adjustment is added to a reference shift amount to determine a shift amount. The product of an excitation signal and an error signal is then calculated and the product is stored in a memory register comprising a plurality of bits. The bits stored in the memory register are shifted either left or right based upon the shift amount. The shift adjustment may be based in part upon the ratio of the excitation signal power estimate and the reference power level. | 10-14-2010 |
