The present invention relates to a system and method for harvesting ambient electromagnetic energy, and more particularly, to the integration of antennas and electronics for harvesting ubiquitous radio frequency (RF) energy, transforming such electromagnetic energy into electrical power, and storing such power for usage with a wide range of electrical / electronic circuits and modules.

Apparatus and methods for attenuating environmental interference are described. A wearable monitoring apparatus includes a housing configured to be attached to the body of a subject and a sensor module that includes an energy emitter that directs energy at a target region of the subject, a detector that detects an energy response signal—or physiological condition—from the subject, a filter that removes time-varying environmental interference from the energy response signal, and at least one processor that controls operations of the energy emitter, detector, and filter.

A system for the stand-off detection of trace amounts of analyte materials such as explosives, chemical warfare agents, toxic industrial chemicals, and the like includes an ion source that is operably connected to an ion collection means and to a sensor. The ion source employs a first gas that is passed through an electrical discharge to produce metastable gas molecules as well as charged particles of various kinds. Ions and other charged particles are removed from the first gas which is then reacted with a second gas having a lower ionization potential to obtain reactant ions of relatively uniform energy. The reactant ions are focused and accelerated into a beam that is directed upon a surface, such as luggage or clothing that is being interrogated, to produce analyte ions which are collected and passed into the sensor that is preferably a differential mobility spectrometer.

A waste fluid collection container, which includes a tray having a floor defined by a periphery, where the floor has a plurality of raised flow enhancing areas and a fluid absorbing member that sits inside the tray. In embodiments, the raised areas are elongated ridges extending outwardly from a central area. In other embodiments, the raised areas are a plurality of studs.

A CMOS-implementable TOF detector promptly collects charge whose creation time can be precisely known, while rejecting collection of potentially late arriving charge whose creation time may not be precisely known. Charges created in upper regions of the detector structure are ensured to be rapidly collected, while charges created in the lower regions of the detector structure, potentially late arriving charges, are inhibiting from being collected.

An adaptive aircraft tail assembly includes a tail boom, and a tail structure. The tail structure has a plurality of control surfaces configured to alter or maintain flight characteristics of the aircraft. The tail structure also has at least (i) one or more photovoltaic cells, or (ii) at least one or more solar thermal collection cells, or (iii) both photovoltaic cells and solar thermal collection cells. The tail structure also includes a rotational pivot configured to rotationally attach the tail structure to the tail boom. Preferably, the plurality of control surfaces are configured so as to be manipulatable to rotate the tail structure about a central axis of the tail boom via the rotational pivot.

A system and method for assembling and operating a solar powered aircraft, composed of one or more modular constituent wing panels. Each wing panel includes at least one hinge interface that is configured to rotationally interface with a complementary hinge interface on another wing panel. When a first and second wing panel are coupled together via the rotational interface, they can rotate with respect to each other within a predetermined angular range. The aircraft further comprises a control system that is configured to acquire aircraft operating information and atmospheric information and use the same alter the angle between the wing panels, even if there are multiple wing panels. One or more of the wing panels can include photovoltaic cells and / or solar thermal cells to convert solar radiation energy or solar heat energy into electricity, that can be used to power electric motors. Further, the control system is configured to alter an angle between a wing panel and the horizon, or the angle between wing panels, to maximize solar radiation energy and solar thermal energy collection. A tail assembly for the aircraft includes a rotational pivot that allows the flight control surfaces to rotate to different orientations to avoid or reduce flutter loads and to increase solar radiation energy and / or solar thermal energy collection from photovoltaic cells and / or solar thermal cells the can be located on the tail structure associated with the flight control surfaces.

A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib associated with the membrane that decreases the gap between the membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously collected whole blood into components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.

Source-collector modules for use with EUV lithography systems are disclosed, wherein the source-collector modules employ a laser-produced plasma EUV radiation source and a grazing-incidence collector. The EUV radiation source is generated by first forming an under-dense plasma, and then irradiating the under-dense plasma with infrared radiation of sufficient intensity to create a final EUV-emitting plasma. The grazing incidence collector can include a grating configured to prevent infrared radiation from reaching the intermediate focus. Use of debris mitigation devices preserves the longevity of operation of the source-collector modules.
