Methods and systems for interactive evolutionary computing may include generating a set of candidate molecules based on an evolutionary scheme in which an objective function is a priori mathematically unexpressed, presenting data based on the set of candidate molecules to one or more users, receiving at least one input from the user(s), the input(s) based on the user(s)'s evaluation of the presented set of candidate molecules, and, based on the input(s), using at least the evolutionary scheme and the input(s) to generate an updated set of candidate molecules, and repeating the presenting and receiving.

An apparatus and method for providing efficient connectivity to the Internet via a satellite communication link. A particularly useful embodiment of the invention comprises a an apparatus and method for webcasting live events over a satellite communication link. Digital multimedia data is converted to a bitstream format by an encoder. The encoder supplies the bitstream data to an uplink subsystem for transmission to a satellite. The satellite retransmits the data to a ground-based facility which makes the content available to subscribers over the Internet, either directly or through an independent Content Delivery Network. A novel TCP proxy process adjusts for propagation delays associated with the satellite path. Preferably, the TCP proxy resides in the uplink and the ground-based receiver that receives the bitstream data that is transported by the satellite, or by a router configured to provide such a TCP proxy process.

An apparatus and method are disclosed for processing phone-in prescription requests. The apparatus is in the form of a prescription processing network that includes a prescription processing system and a communication device remotely located from the prescription processing system. The communication device is used to establish a communication channel with the prescription processing system and submit a prescription request over the communication channel. A pharmacist, associated with the prescription processing system, prepares a completed prescription form based, at least in part, on the submitted prescription request. The prescription processing network also includes a pharmacy for receiving the completed prescription form, and filling the prescription request based on the completed prescription form.

A manipulator for a fiber optic cable assembly (FOCA) provides microradian accuracy in control of the direction of a beam emanating from the FOCA. Such manipulators can control FOCAs to control the incidence angles of beams at a beam combiner in a beam-combining unit. Accordingly, fewer additional optical elements are required for control of input paths in the beam-combining unit. The manipulator and the beam-combining unit are accurate enough for use in an interferometer that combines beams with different frequencies and polarizations. One such interferometer includes a Zeeman split laser providing a heterodyne beam. A beam splitter separates frequency components of the beams, and AOMs increase the frequency separation between the separated beams. The separated beams can be sent via optical fibers to the beam-combining unit, which combines the beams for use in interferometer optics.

A Low Earth Orbiting satellite system provides location and data communications services to mobile users equipped with a receiver/transmitter. The receiver/transmitter acts as a transponder that responds to a query transmitted over the satellite network. The response is sent after a precisely controlled time interval after the transponder receives the query so that the ground station can estimate the length of the propagation path from the satellite to the transponder. The transponder also transmits the response at a frequency that is proportional to the frequency of the received query so that the ground station can estimate the first and second derivatives of the length of the propagation path according to the measured Doppler shift. The ground station also estimates the satellite positioning using telemetry from the satellite obtained from the on-board GPS receiver. The position of the user terminal relative to the satellite position is then determined from the path length measurements. Given the satellite position and velocity, the measured path length and first and second derivatives determine the angle between the direction of satellite motion and the line of bearing to the user terminal. This angle defines a cone with the satellite at the origin. The user terminal position is somewhere on the circle defined by the cone and the estimated path length. The intersection of this circle with the surface of the Earth yields two possible user positions, which ambiguity can be resolved by three techniques: (1) use of knowledge of which beam the signal was received in; (2) use of earlier position data; or (3) using nearby satellites to receive the signal. The user terminal uses a single frequency reference to provide timing for the receive and transmit frequency synthesizers and for the analog-to digital and digital-to-analog converters.

A resilient thin membrane shield of substantially rectangular planform includes a peel plied adhesive strip along its upper edge and a tapered tubular segment at its center. The walls of the tubular segment are tapered in thickness and along the axis thereof, forming a feathered edge at the end opening. The membrane, furthermore, may include enlarged section ribs and edge beads for unfolding the membrane.

A toy-like cereal serving apparatus integrates a bowl, milk container and serving spoon into a common theme. The theme is that of a sailing-ship. The bowl is boat-shaped; the milk container is pivotally supported on top of the ship's mast; and the serving spoon is stored on the boat-shaped bowl in the position of the rudder.
摘要:
A toy that simulates a creature of nature such as a turtle is described. The toy includes a shell having two separable parts that are hinged together. A soft body portion of the creature fits within the shell. the shell has wheels to permit the toy to be pulled or ridden. The soft body portion has sufficient thickness to permit the use thereof as a pillow.
