Abstract: This disclosure relates to pairing of a different cryptographic key with each pointer in a data structure to form a crypto-pointer. The cryptographic key is used to encrypt the contents of all data stored at the physical location on the storage device indicated by the pointer. Preferably the only data accessible in an unencrypted form is contained in cells that are reachable from root-set crypto-pointers. Once the crypto-pointer associated with a particular memory cell is deleted, normally by overwriting or explicitly zeroing the crypto-pointer, the contents of the memory cell become inaccessible because the data stored at that cell is in encrypted form (cipher text) and the crypto-pointer that included the cryptographic key for decrypting the cipher text has been deleted from the system.

Abstract: An apparatus and method is disclosed for providing an electrostatic discharge protection circuit for compound semiconductor devices and circuits. The electrostatic discharge protection circuit comprises a first terminal and a second terminal. The electrostatic discharge protection circuit further comprises a transistor shunt element that is operably coupled between the first terminal and the second terminal; the transistor shunt element is capable of providing a bi-directional discharge path between the first terminal and the second terminal. The electrostatic discharge protection circuit further comprises a shut-off element that is operably coupled with the second terminal; the shut-off element is capable of keeping the transistor shunt element turned-off.

Abstract: A local positioning system comprises a plurality of sensor elements that may communicate with mobile units in a wireless fashion. The responsiveness of the mobile units is measured by yes/no answers and averaged so as to provide a measure of the distance of a mobile unit to a specified sensor element. Based on this measure and the known positions of the sensor element, the position of the mobile unit is estimated, for instance by a model of ideal springs.

Abstract: In various embodiments, a saw chain is provided that includes a rail engaging link that has an offset footprint within the link itself and/or with respect to other links in the chain that are adapted to ride on the same rail. Saw chains as provided may be used in a variety of applications, including but not limited to wood cutting and aggregate cutting applications.

Abstract: The present invention relates to a quadrature divider which may be used in a phase locked loop or frequency synthesizer or with a single side band mixer. According to a preferred embodiment the divider takes a quadrature input and has a quadrature output. The divider has four analog mixers 1, 2, 3 and 4. The first two mixers 1, 2 take the in-phase quadrature input, while the second mixers 3, 4 take the quadrature-phase quadrature input. The outputs and feedback loops of the mixers are properly arranged such that the in-phase and quadrature-phase outputs of the divider have a determinisitic phase sequence relationship based on the phase sequence relationship of the corresponding quadrature inputs. Third order harmonics may be minimized or reduced by addition or subtraction of the mixer outputs. As the divider is able to take a quadrature input, there is no need for a dummy divider in the phase locked loop, thus saving space and power.

Abstract: Embodiments of methods and apparatuses for searching contents, including structured search are described herein. Embodiments of the present invention use tree structures (or more generally, graph structures), layout structures, and/or content category information to capture within search results relevant content that would otherwise be missed, to reduce the incidence of false positives within search results, and to improve the accuracy of rankings within search results. Embodiments of the present invention further use tree structures (or more generally, graph structures), layout structures, and/or content category information to extend search results to include sub-document constituents. Embodiments of the present invention also support the use of distribution properties as criteria for ranking search results.

Abstract: Embodiments provide methods, systems, and apparatuses to generate and send a command message to a mobile device connected to a first wireless network to command the mobile device to connect to one of one or more candidate wireless networks. The message includes embedded service flow context information of the candidate networks including one or more attributes of the candidate wireless networks that are of potential interest to the mobile device in determining a performance or security impact if the mobile device switches to the one or more wireless networks. The mobile device can conditionally refuse the command if the candidate wireless networks are unable to meet one or more service level requirements of the apparatus. Other embodiments are disclosed and described.

Abstract: A method of making a surgical template used for a computer-guided dental implant surgery includes the steps of: establishing implant planning data of a patient's jaw, producing a digital plaster model of the patient's jaw, allowing the digital plaster model to have the implant planning data, integrating the digital plaster model with the implant planning data to obtain a digital machining data, holding and machining a modeling block at a machining position according to the digital machining data to form a solid jaw model corresponding to the patient's jaw and having teeth, gums, and at least one implant-position indicating structure, mounting a positioning member at the implant-position indicating structure, and producing a negative template body from an assembly of the solid jaw model and the positioning member with a thermoplastic dental material by a molding process or a vacuum forming process.
