Abstract: In one or more embodiments, a multi-axis articulated solar light shade that protects elements of a space-based sensor from direct solar illumination includes a base; a partial conical baffle tube having a first end portion, a second end portion, an elongated curved portion defining a shade between the first and second end portions, and an opening defined in an interior of the elongated curved portion, the first end portion rotatably attached to the base; and a visor pivotably attached to the second end portion. The partial conical baffle tube may be selectively rotated about a sensor line-of-sight in response to the sun's position relative to the sensor line-of-sight; and the visor may be selectively pivoted relative to the partial conical baffle tube in response to the sun's position relative to the sensor line-of-sight so as to protect the sensor from the direct solar illumination at any given time or any given orbital position.

Abstract: A handoff method and apparatus are disclosed for use in a wireless communication network in which a base station servicing a call selects a handoff candidate base station based in part on subscriber-specific information. For example, in some wireless networks, certain subscribers can only access a limited number of base stations and the subscriber-specific information identifies such access limitations. A central control processor provides the subscriber-specific information to the base station servicing the call during the course of the call. The base station is then operable to select a handoff candidate from the one or more neighbor base stations based on one or more neighbor base station signal quality measurements and subscriber-specific information.
