Abstract: An aircraft defining an upright orientation and an inverted orientation, a ground station; and a control system for remotely controlling the flight of the aircraft. The ground station has an auto-land function that causes the aircraft to invert, stall, and controllably land in the inverted orientation to protect a payload and a rudder extending down from the aircraft. In the upright orientation, the ground station depicts the view from a first aircraft camera. When switching to the inverted orientation: (1) the ground station depicts the view from a second aircraft camera, (2) the aircraft switches the colors of red and green wing lights, extends the ailerons to act as inverted flaps, and (3) the control system adapts a ground station controller for the inverted orientation. The aircraft landing gear is an expanded polypropylene pad located above the wing when the aircraft is in the upright orientation.

Abstract: Method and apparatus for generating a jitter reduced clock signal from signal transmitted over a communication medium includes receiving, with high speed data interface circuitry, a modulated signal that includes a binary encoded data stream. A recovered clock signal is generated from the modulated signal and tracks the long-term drift in the modulated signal. A jitter reduced clock signal is generated by filtering the recovered clock signal with a filtering circuit having a bandwidth sufficient to remove jitter while allowing the jitter reduced clock signal to track the drift in the modulated signal.

Abstract: Embodiments of the invention provide a method, distributed antenna system, and components that generate a jitter reduced clock signal from a binary encoded data stream transmitted over a communication medium. The method includes receiving a modulated signal that includes the binary encoded data stream and generating a recovered clock signal that is phase locked to the binary encoded data stream. The method further comprises generating a stable recovered clock signal by filtering the recovered clock signal to remove jitter, while allowing the clock signal to track long-term drift.

Abstract: A system is provided for adjusting power provided to a device. The system can include power sourcing equipment and a sub-system. The power sourcing equipment can provide power to a powered device via a channel. The sub-system can determine an amount by which to increase the power based on a resistance of the channel. The power sourcing equipment or the powered device can adjust the power (or load) responsive to a command from the sub-system. The sub-system can include a measurement device and a processor. The measurement device can measure an output voltage of the power sourcing equipment, an input voltage of the powered device, and a current on the channel. The processor can determine the resistance of the channel based on the output voltage, the input voltage, and the current. The processor can output a command specifying an increase or decrease in power supplied by the power sourcing equipment.

Abstract: A monetary game of chance for a petroleum product, such as gasoline, includes a game ticket having a face purchase price; and at least two mutually exclusive options for winning. The first option is an award to exercise the face purchase price to purchase a petroleum product at a current retail selling price over a first time period. The second option is an award to purchase a fixed quantity of petroleum product over a second period of time.

Abstract: A clamp for affixing a pliable bag to a container and to control the crawling insect population at or near the container. The clamp contains an insect bait station on one surface thereof. The device can be deformed to an open position and normally assumes a closed position. While in the closed position, the clamp is in condition to secure a bag to a container. The clamp may be deformed to place it in position on the lid of a container, and to allow release of the bag from the container.

Abstract: A play yard which is light, portable and operable for easily and quickly transforming between a collapsible configuration and an expanded configuration. The play yard opens up automatically by simply releasing the frame and allowing it to unfold. The play yard includes a frame formed of a flexible material including a first bottom loop forming a rectangular shape and a second elevated loop contacting the first loop at two points. An envelope made of laminar material is attached at selected points to the frame to form a partially enclosed play area. An opening in a top portion of the envelope permits access to the enclosed play area. In a preferred embodiment, the play yard has a removable top for covering the opening when desired.
