Abstract: Systems and methods for hysteretically controlling Light Emitting Diodes (LEDs) when the input voltage is greater than or equal to 18 volts. An example system includes one or more LEDs and a circuit electrically coupled to the one or more LEDs. The circuit hysteretically controls an input voltage supplied to the one or more LEDs based on a sensed electric current that passes through the LEDs. The circuit includes a MOSFET switch for switching on and off the input voltage supplied to the one or more LEDs, a current sensing subcircuit including a first integrated circuit (IC) for sensing the current flowing through the one or more LEDs, a hysteretic comparator circuit including a second IC for generating a hysteretic control signal based on the sensed current, and a switch driver including a third IC for controlling operation of the switch based on the generated hysteretic control signal.

Abstract: An antenna for a micro air vehicle (MAV) takes the form of a wrap-around antenna (e.g., wrapped around a portion of the MAV) that selectively emits radio signals in different directions depending on a frequency selected by a radio altimeter in the MAV. The radar altimeter may be a pulsed or a frequency modulated continuous wave (FMCW) radar altimeter. The wrap-around antenna includes groups of radiating elements in which at least each group includes an average height that is different from an average height of an adjacent group. Further, the average height of the group determines which group will emit the signals most efficiently so that a desired sector of space may be covered by the signals emitted from the antenna. In one example, the center frequency of the radar altimeter may be controlled in a deterministic manner to cause the radiating elements to successively cover desired sectors of space.

Abstract: A method, a system, and an oxygen delivery boomlet are configured to provide an additional partial pressure of oxygen to an aviator. The boomlet includes a conduit configured to receive an oxygen flow from a positive pressure oxygen source. A nozzle is in communicative connection with the conduit such that the oxygen flow the conduit receives is conducted to the nozzle. The nozzle is configured to direct the conducted flow of oxygen to an interpalatine region of the aviator. The boomlet is configured for attachment to a microphone boom.

Abstract: System and method for interactive video game fitness equipment. Fitness hardware (e.g., an exercise bicycle, a stair machine, treadmill, elliptical trainer, rotary climbing wall, or other fitness equipment) interacts with a video game, optionally via various devices, e.g., a PC, gaming console, or other hardware and/or software device or system capable of implementing an interactive application), for an immersive hybrid exercise/game user experience.

Abstract: A shoe provides a suspended orthotic system that includes at least a contoured, three-dimensional chassis configured with a heel cup. The chassis provides the primary support and determines the shape and form of the shoe. The chassis receives a footbed, which includes a first material integrally formed with a second material, both materials operating to provide an orthotic benefit. A shoe sole includes a number of pods that are selectively arranged and coupled to the chassis to actively suspend the chassis and the footbed. The shoe can further include a dynamic arch support system that manually or automatically adjusts the arch region of the shoe. The shoe may be more comfortable, provide biomechanical advantages, be lighter, and be more stylish than traditional shoes.

Abstract: Systems and methods for monitoring Required Navigational Performance (RNP) Procedures and reducing nuisance Enhanced Ground Proximity Warning System warnings including a processor, a memory with RNP instructions and data, and a communication device. The processor accesses the RNP data and instructions from the memory, and uses the communication device to obtain flight information from a Flight Management System of an aircraft. When the processor determines that the aircraft is in RNP space, the processor projects an RNP envelope and modifies a warning envelope of an EGPWS to coincide with the RNP envelope if the EGPWS warning envelope extends farther than the RNP envelope.

Abstract: Large volumes of electronic documents can be printed from a network, such as the Internet, using a batch printing technique. Sizable print jobs are broken into batches, which are sent sequentially to a printer executable component at the client side. As one batch finishes printing, another batch is sent to the printer executable component. Logs are kept so that if there is an interruption in the printing, a print job can be re-started at any batch, instead of having to re-start printing in its entirety from the beginning. The electronic documents may also be downloaded for storage alternatively or in addition to printing. Stamps may be applied en masse to the electronic documents to be printed.

Abstract: A ski in accordance with the invention increases in width from a tip or shovel portion to a mid-portion. The mid-portion includes at least a slight sidecut. The ski then decreases in width from the mid-portion to a tail portion. The ski also includes an undersurface with a substantial portion being rockered. A substantial portion of the mid-portion of the ski is not rockered.

Abstract: A system and method stores electronic legal documents, such as email messages, in a database system such that electronic characteristics associated a native format of the electronic legal documents are substantially preserved. The electronic characteristics that are preserved include metadata and conversational threading information, directory path information, attachments, and other electronic document information. Once in the database system, the stored electronic legal documents are indexed and can be searched by users at terminals. The users at the terminals are provided with access to the database system via a server. The terminals have user interfaces to provide the users with a variety of searching, processing, and saving capabilities, including the ability to follow conversation threads, view attachments, and index and retrieve selected electronic legal documents in a manner that allows use of the stored electronic characteristics.

Abstract: A generator controller, in its various embodiments, displays genset fault messages, a genset elapsed time hour meter, service countdown reminder, monitors battery voltage changes over multiple periods of time to establish and display the “battery level,” uses the “battery level” to automatically start and stop the genset, and accepts multiple run requests from AC loads such as HVAC systems, and incorporates safety or other start inhibit features.
