Abstract: Disclosed are systems and methods of employing a multi-ring encryption approach to secure a data payload. Each ring of encryption may be encrypted from a key derived from a password, such that each subsequent ring of protection is protected by a key derived from the key used to encrypt the previous ring of protection. Further, hardware-based encryption may be employed in one or more of the rings of protection to bind the encrypted payload to the hardware. Such systems and methods may be used to reduce the ability to parallelize an attack on encrypted data while also permitting password-related data to be synchronized across a network.

Abstract: Multi-channel high resolution segmented resistor string digital-to-analog converters (DACs) suitable for realization in a single integrated circuit. The DACs incorporate a primary resistor string shared by all channels, and one or more additional pluralities of additional resistor strings for additional resolution. The primary resistor string may be buffered to limit the effect of loading thereon by the plurality of resistor strings coupled thereto. Current sources may also be coupled to the resistor strings coupled to the primary resistor string to also avoid loading of the primary resistor string. A trimmable resistor string of fewer bits may be connected to the primary resistor string for laser trimming. In the embodiment disclosed, a plurality of secondary and tertiary resistor strings are used, with leapfrogging minimizing the switches required.

Abstract: A directional antenna formed by associating a stationary generally omni-directional antenna element with an RF reflector formed from, for example, a folded, parabolic or elliptical RF reflecting surface. Rotating the RF reflector about the stationary antenna element creates a directional characteristic in the resulting antenna over, for example, a 360 degree range of azimuth. Rotation of the RF reflector may be remotely driven by a motor coupled, for example, to a gear connected to the RF reflector. The direct connection of the antenna element and the enclosed lightweight rotating assembly provide a reliable, easy to install and cost effective antenna.
