A sense amplifier-based flip-flop includes a first latch, a second latch, a floating reduction unit, an input signal applying unit, a ground switch and a delay reduction unit. The first latch outputs a signal to a first output terminal pair, and outputs an evaluation signal pair corresponding to an input single pair to the first output terminal pair. The second latch latches the evaluation signal pair and outputs the evaluation signal pair to a second output terminal pair. The floating reduction unit is controlled by signals of the first output terminal pair and is operationally connected between current passing nodes of the first latch to prevent the first output terminal pair from floating. The input signal applying unit is disposed between the current passing nodes and a ground terminal, and receives the input signal pair. The ground switch is disposed between the input signal applying unit and the ground terminal, and is controlled by the clock signal. The delay reduction unit is disposed between the input signal applying unit and the ground switch, and reduces a signal delay from when the clock signal to when the evaluation signal pair is output from the second output terminal pair.

A radiation distribution system designed to produce a batwing distribution. The system may be used with radiative sources emitting in the visible spectrum or in other spectra. The system comprises a specially shaped lens disposed over a radiative source, such as an LED, for example. The lens and source are arranged between two reflector bodies, both of which have an elongated reflective surface that faces the source. The reflector bodies each have two different reflective surfaces that face outward and away from each other. The lens and both reflective surfaces work in concert to redirect a portion of the emitted radiation to create the desired batwing distribution. Several sources may be arranged linearly between a single pair of reflector bodies on a common surface to create a linear array of sources. Likewise, multiple linear arrays may be combined to form a two-dimensional array. In the two-dimensional configuration, linear arrays of sources are disposed on both sides of a reflector body, so that both of the reflective surfaces are utilized.

A physiologic data acquisition system includes an analog input, a sigma-delta front end signal conditioning circuit adapted to subtract out DC and low frequency interfering signals from and amplify the analog input before analog to digital conversion. The system can be programmed to acquire a selected physiologic signal, e.g., a physiologic signal characteristic of or originating from a particular biological tissue. The physiologic data acquisition system may include a network interface modulating a plurality of subcarriers with respective portions of an acquired physiologic signal. A receiver coupled to the network interface can receive physiologic data from, and send control signals and provide power to the physiologic data acquisition system over a single pair of wires. The network interface can modulate an RF carrier with the plurality of modulated subcarriers and transmit the resulting signal to the receiver across a wireless network. An integrated circuit may include the physiologic data acquisition system. Also included are methods for acquiring physiologic data comprising the step of selectively controlling an acquisition circuit to acquire the physiologic signal.

The system includes a power monitoring gateway with a port configured to communicate with an internet protocol network using an internet protocol address. The power monitoring gateway is also configured to communicate with the plurality of power distribution units through a communication link that does not use internet protocol addressing. The communication link in some embodiments is a wireless link. In other embodiments, the communication link uses a single pair of wires with the power monitoring gateway and the power distribution units configured in a daisy chain topology.

The present invention comprises a method and an apparatus for three dimensional modeling to allow dense depth maps to be recovered, without previous knowledge of the surface reflectance, from only a single pair of stereo images. Several initial steps are performed for stereo and radiometric calibration and rectification for obtaining accurate results. The apparatus for the stereo images acquisition includes internal light sources, these are automatically commuted by a illumination control in order to fulfill the reciprocity property, a stereo camera head composed by the necessary optics to acquire the reciprocal stereo images and a compatible PC interface. The invention is faster than other systems since it requires only two images for obtaining a dense depth model of objects with an arbitrary surface reflectance distribution allowing the system to be used in a wide range of applications such as metrology, quality control, medical and dynamic three dimensional modeling.

An aircraft light assembly comprises a light apparatus configured to be supported in a space on the body of an aircraft. The apparatus has one or more light emitting diodes (13) generating visible light and an outer structure overlying the LEDs. The outer structure includes a light transmission portion through which visible light from the LEDs can pass, and a metallic portion with an outer surface exposed to the external airflow. A heat-transmitting connection thermally links the LEDs to the metallic portion so that heat from the LEDs flows to the outer surface and is dissipated to the external airflow. The light assembly is configured to be secured in a conventional socket for an incandescent navigation light bulb and to receive the electrical current supplied thereto by the aircraft electrical system. Civilian applications of the unit have only visible LEDs. When the unit is for a military aircraft, it has electric circuitry connected with a visible light source and an IR light source, and the electric circuitry is configured to process the input current from the socket and based thereon operate in either a visible mode or covert IR mode. Where the current is in one electrical state, such as for example a certain voltage, the electric circuit sends power only to the visible light source. When the current is in a different electrical state, e.g., a different voltage level, the circuitry sends power only to the IR source, and no visible light is emitted. Different input current voltages or characteristics are also used to cause the IR emitter to flash in various patterns that can be programmed into the unit. All control may be accomplished over a single pair of wires, as in existing systems that do not have IR mode capability. To upgrade existing aircraft, light source units a shaped to fit in the apertures for existing lenses over incandescent navigational fixtures.

Highly specific and sensitive methods were developed for multiplex amplification of nucleic acids on supports such as microarrays. Based on a specific primer design, methods include five types of amplification that proceed in a reaction chamber simultaneously. These relate to four types of multiplex amplification of a target DNA on a solid support, directed by forward and reverse complex primers immobilized to the support and a fifth type—pseudo-monoplex polymerase chain reaction (PCR) of multiple targets in solution, directed by a single pair of unbound universal primers. The addition of the universal primers in the reaction mixture increases the yield over the traditional “bridge” amplification on a solid support by approximately ten times. Methods that provide multitarget amplification and detection of as little as 0.45-4.5×10⁻¹² g (equivalent to 10²-10³ genomes) of a bacterial genomic DNA are disclosed.

The present invention relates to a footwear system that is comprised of a pair of footwear with at least one transparent, semi-transparent or translucent special display area(s) (SDA) and system of innerliners. The system of innerliners can be comprised of either at least two user interchangeable pairs of innerliners or a single pair of innerliners that can provide multiple combined appearances from the footwear, when the innerliners are switched from one foot to the other, reversed or rotated on the foot. The innerliners are specifically designed and engineered to be displayed through the footwear, and the footwear is specifically designed and engineered to display the innerliners providing an emanating effect. The present invention provides a large number of user desirable combinations of footwear with SDA and innerliners that can be created by using a footwear system comprised of footwear with at least one SDA and a system of specifically designed innerliners. Users can create multiple combined appearances from a single pair of footwear by simply changing or modifying their innerliners.

The shoe with interchangeable covers is a modified pair of women's shoes consisting of a base, a sole with a removable heel, and a cover which is attached to the base and the sole with two sets of straps joining under the sole and fastened together with hook and loop type fasteners. The base of the shoe features a layer of padding for extra comfort and low rising vertical sides for supporting the interchangeable cover. The sole of the shoe is formed with a pair of notches on the bottom, one in the toe area and one in the arch area. These notches serve as guides into which the straps are placed and secured to one another. The cover can be made in various styles from dressy and elegant to casual and sporty by adding decorative items, such as zippers, buttons, bows, and the like and by varying the heel height and width. The interchangeable covers and heels allow the owner to have numerous pairs of shoes for the price of one. Thus any woman could save money through the purchase of one pair of shoes as opposed to purchasing shoes to coordinate with every outfit in her wardrobe. Additionally, the female traveler could pack a single pair of shoes to complete a number of ensembles, thereby reducing the load with which she travels.

A sensor, a system of direct measurement using that sensor, and a method of direct and simultaneous measurement of conductivity and dielectric constant of a fluid, particularly high impedance, hydrocarbon-based fluids. The sensor has a cell that holds the fluids to be measured between a single pair of coaxial, bare metal electrodes connected through interface circuitry to measurement circuitry preferably implemented in one or several IC's. The sensor has a mutually compatible electrode geometry that provides both the correct cell constant for measurement of conductivity of hydrocarbons fluids (typical range 0-100,000 pS/cm), and a bulk capacitance (for use in dielectric constant measurement) in the range of measure of readily available low cost commercial IC's (having a typical capacitance measurement span of <10 pF, with a total bulk capacitance at the chip of <20 pF). The cell conductivity constant for use with hydrocarbon-based oils having a conductivity in the range of 1 to 500,000 pS/M is preferably less than or equal to about 0.1. The cell bulk capacitance with hydrocarbon fluids inside the sensor results in a bulk capacitance of at least about 4 pF. In one embodiment, the electronic circuitry is a Microcontroller/DSP that both generates synchronous drive signals at various frequencies, for both conductivity and dielectric constant measurements while directly digitizing and numerically processing the sensor output.

The subscriber end of a network, such as a Fiber-To-The-Home (FTTH) network, utilizes a pair of wires to provide both power source (battery) status information and operating power over the pair of wires by superimposing tones, which indicate the status of the battery, onto a DC voltage on the pair of wires.

The foam piece in contact with the patient is more porous than the foam piece in contact with the positioner support plate for greater patient comfort. A solid plastic connector clip connects the pad arrangement with the surgical postioner support in press-fit relation.

Systems and methods for automatically modifying an annotated bilingual segment pair are provided. An annotated bilingual segment pair (“Pair”) may be modified to generate improved translation rules used in machine translation of documents from a source language to a target language. Because a single Pair may be used to translate a phrase, many Pairs are used in a machine translation system and manual correction of each model is impractical. Each Pair may be modified by re-labeling syntactic categories within the Pair, re-structuring a tree within the Pair, and/or re-aligning source words to target words within the Pair. In exemplary embodiments, many alternate Pairs (or portions thereof) are generated automatically, rule sequences corresponding to each are derived, and one or more rule sequences are selected. Using the selected rule sequence, a modified Pair is distilled.

The frequency of the dot clock in an image display device is adjusted by calculating a first image characteristic from the differences between adjacent picture elements, varying the phase of the dot clock, determining whether the frequency of the dot clock is correct from the way the first image characteristic varies according to the phase of the dot clock, and changing the frequency if it is incorrect. The first image characteristic is, for example, the maximum difference, the histogram distribution of the differences, or a ratio calculated from the histogram. The phase of the dot clock may be adjusted according to a second image characteristic, such as the difference between a single pair of pixel values, which is also measured over a range of dot-clock phase settings.

A network element (NE) in a communications network decodes a data stream received over a communication link. Upon synchronization with the data stream, the NE determines a performance metric for the link based on a number of transmission code violations. In response to the performance metric exceeding a predetermined threshold, the NE commands the selection of a different link to carry the data stream via a switch signal. The switching or rerouting of signals may occur between a single pair of NEs (e.g., point-to-point span) or in a more complex topology having a plurality of interconnected NEs.
