    摘要： A reconfigurable zone plate lens is disclosed. Some embodiments may include a central annular element having a first a first circumference centered about a central axis. Embodiments may also include a plurality of concentric annular elements of increasing circumference centered about the central axis and the central annular element, where each annular element is positioned around an annular element having a smaller circumference. The annular elements of some embodiments may each be adapted to be in either an active or inactive state where the active and inactive annular elements form a plurality of alternating active rings and inactive rings. Each active ring may include one or more annular elements in an active state and each inactive ring may include one or more annular elements in an inactive state. Each annular element may include one or more liquid crystal display (LCD) elements or micromirrors. Other embodiments are disclosed and claimed.

    摘要： According to one aspect of the invention, a method and apparatus for polarizing electromagnetic radiation is provided. The electromagnetic radiation may be divided into first and second portions, substantially all of the first portion may be linearly polarized in a first direction and substantially all of the second portion may be linearly polarized in a second direction, the first direction being substantially orthogonal to the second direction. The linear polarization of at least one of the first and second portions may be changed such that substantially all of both of the first and second portions are linearly polarized in a third direction. At least one of the first and second portions may be redirected such that substantially all of both the first and second portions are propagating in a fourth direction.

    摘要： For at least one disclosed embodiment, a die may be provided that includes a transmission line (or waveguide) and a signal-generating device to generate a pulse on the transmission line and to receive a pulse from the transmission line. A plurality of transistors may be provided along a length of the transmission line to change an impedance of the transmission line. This may change a speed of the pulse along the transmission line or change an effective length of the transmission line. A control device may also control the plurality of transistors based on a sensed temperature of a thermistor device.

    摘要： A device uses bluetooth techniques to communicate with electronic devices in an airplane. During take off or landing, the radio on board the airplane operates in bluetooth mode to send a global poll to all devices requesting that they respond. If a device responds, then it indicates that the device is on at an unauthorized time. This informs the crew that they should try to find the unauthorized device and turn it off.
