Abstract: A nanodosimeter device (15) for detecting positive ions induced in a sensitive gas volume by a radiation field of primary particle, comprising an ionization chamber (10) for holding the sensitive gas volume to be irradiated by the radiation field of primary particles; an ion counter system connected to the ionization chamber (10) for detecting the positive ions which pass through the aperture opening and arrive at the ion counter (12) at an arrival time; a particle tracking system for position-sensitive detection of the primary particles passing through the sensitive gas volume; and a data acquisition system capable of coordinating the readout of all data signals and of performing data analysis correlating the arrival time of the positive ions detected by the ion counter system relative to the position sensitive data of primary particles detected by the particle tracking system.

Abstract: A method for image processing of a digital image comprising the steps of determining one or more sets of pixel characteristics; determining for each pixel characteristic set, an image editing function; providing a mixing function algorithm embodied on a computer-readable medium for modifying the digital image; and processing the digital image by applying (22) the mixing function algorithm based on the one or more pixel characteristic sets and determined image editing functions. Various mixing function algorithms are described. An application program interface embodied on a computer-readable medium comprising a first interface to receive the coordinates of the image reference points, and a second interface to receive the image editing function is also provided. The application program interface may represent the image reference points by a graphic tag (10).

Abstract: A low distortion power amplifier, where N is greater than 1, comprising an input divider (10) for dividing a received input signal (100), and outputting a first signal (104) and a main signal (102), a carrier cancellation component (50) connected to the input divider (10) for receiving the first signal (104) and outputting a distortion signal (114), an input attenuator (22) receiving the main signal (102) and outputting an attenuated main signal (118) to an input delay device (24) yielding a delayed, attenuated main signal (118), and an N way distortion cancellation component (52) having a first input connected to the carrier cancellation component (50) for receiving the distortion signal (114) and a second input connected to the input delay device (24) for receiving the delayed, attenuated main signal (118) and an output for outputting an amplified output signal (144) having low distortion.

Abstract: A template for placing electrodes for electroencephalography of acute-brain-injured victims is provided which modifies the number of electrode locations from that taught by the standard 10-20 System, and which has indicia that can be quickly and easily read by non-experts during emergency application; an acquisition unit is provided which provides a turn-key interface to the non-expert personnel who routinely attend acutely brain-injured victims, preventing change or modification of the electroencephalogram parameters by the field technician, while at the same time allowing extensive control over parameters by a remote expert EEG reader; and a method and system is provided using the template and acquisition unit of the present invention with one of a plurality of remote readers who are part of a network of trained EEG readers.

Abstract: A window shutter frame for attaching window shutters to a wall comprising an elongate frame base having a first length, a top surface, a bottom surface, and a first longitudinal axis, the top surface having a mounting channel with a first width, the mounting channel extending parallel to the first longitudinal axis of the frame base along the entire first length of the frame base, the mounting channel having a base surface and a first side surface and a second side surface, the base surface of the mounting channel having one or more mounting points through which fasteners may be disposed; and an elongate concealing strip for insertion into the mounting channel having a second width, a second length, and a second longitudinal axis, the second width of the concealing strip being approximately equal to the first width of the mounting channel, the second length of the concealing strip being approximately equal to the first length of the frame base, such that upon insertion of the concealing strip into the mountin

Abstract: A garment for use in watersports to protect one or more than one vulnerable region of a person's body considered susceptible to injury associated with repetitive contact with a hard surfboard surface, comprising a body garment (10) having an inside surface and an outer surface; and one or more than one cushioning pad (12, 14, 16, 18, 20) connected to the body garment (10), disposed adjacent the inside surface, or the outer surface, or the inside surface and the outer surface, and positioned in juxtaposition to the one or more than one vulnerable region of the body, and one or more than one insert pad (44) for insertion into one or more than one pocket (26). The vulnerable regions may be optionally selected from the group consisting of the body area in proximity to the ribs, upper hips, elbows, inner elbows, knees, ankles, front of ankles adjacent the feet, and lower back.

Abstract: An N way carrier cancellation coupler (160), N being greater than 1, for use in a feed forward power amplifier (6), comprising a first N way divider (162), a second N way divider (166), an N way combiner (168), N carrier cancellation couplers (164), the inputs of each of the N carrier cancellation couplers (164) connected to the first N way divider (162) and the second N way divider (166), and the output of each of the N carrier cancellation couplers connected to the N way combiner (168). An M way distortion cancellation coupler (180) is also provided, as well as a feed forward power amplifier comprising a feed forward power amplifier having a first loop and a second loop, an N way carrier cancellation coupler (160), or an M way distortion cancellation coupler (180), or both.

Abstract: A system for separating a liquid and a gas including a separation vessel (30) with an inlet (28) for a gas/liquid mixture. Outlets (40, 42) for the fluids are disposed at different heights in the vessel. The outlets are controlled by turn-up vortex amplifiers (fluidic valves TuVAs) that include a supply port (40, 42), a control port (36, 38) and an outlet port (48, 50). The control port is supplied from the vessel at an intermediate level between the outlets, so that a change of flow in the control port alters resistence to flow through the valve.
