Abstract: The inflow control means comprise either a contact buffer or a buffer reservoir and pump means or both in combination with the inlet of a soil-based filter bed like a root space installation.   The   contact   buffer   is   in  direct   flow communicating contact with an upper section of the filter bed on the infiltration side and dimensioned in adaptation to the throughput capacity of the soil-based filter bed such that variations in the waste water inflow are evened out. The same effect is achieved by the buffer reservoir and pump means wherein  the  pump  delivers  waste  water  from  the  buffer reservoir to the inlet and excess waste water is returned from the inlet to the buffer reservoir through a return line having a receiving end at a level which is preferably adjustable relative to the top surface of the filter bed. For evening out large  differences  in  the waste water  inflow,  the  contact buffer and the buffer reservoir including the pump means are preferably  combined  such  that  the  buffer  reservoir  flow communicates with the cotact buffer. The pump means, then, are adapted to be operated in the event that the variation in the waste  water  inflow  exceeds  the  predetermined  waste  water inflow variations buffered by means of the contact buffer.

Abstract: The present invention provides a method for detecting whether an alarm circuit is operating outside its sensitivity range, the alarm circuit having a background signal and a preset alarm threshold signal. The method involves a) increasing the background signal by a gain factor to produce a first test signal; b) comparing the first test signal against an alarm threshold signal; c) reducing the background signal by a reduction factor to produce a reduced background signal; d) increasing the reduced background signal by a gain factor to produce a second test signal; and e) comparing the second test signal against the alarm threshold signal. The alarm unit is operating outside its sensitivity range when the first test signal is less than the alarm threshold signal or the second test signal is greater than the alarm threshold signal. The present invention also provides a method for maintaining an alarm circuit within its sensitivity range, the alarm circuit including an emitter and a detector and having a background signal and a preset alarm threshold signal. The method involves a) increasing the background signal by a gain factor to produce a first test signal; b) comparing the first test signal against an alarm threshold signal; c) reducing the background signal by a reduction factor to produce a reduced background signal; d) increasing the reduced background signal by a gain factor to produce a second test signal; e) comparing the second test signal against the alarm threshold signal; and f) adjusting the emitter output and/or the alarm threshold signal if necessary to maintain the first test signal greater than or equal to the alarm threshold signal and the second test signal less than or equal to the alarm threshold signal.

Abstract: A phrase recognition method breaks streams of text into text "chunks" and selects certain chunks as "phrases" useful for automated full text searching.  The phrase recognition method uses a carefully assembled list of partition elements (10) to partition the text into chunks, and selects phrases from the chunks according to a small number of frequency based definitions (20). The method can also incorporate additional processes such as categorization of proper names (30) to enhance phrase recognition. The method selects phrases quickly and efficiently, referring simply to the phrases themselves and the frequency with which they are encountered, rather than relying on complex, time-consuming, resource-consuming grammatical analysis, or on collocation schemes of limited applicability, or on heuristical text analysis of limited reliability or utility.

Abstract: Repeat fixation for medical procedures is accomplished using a non-invasive locator, specifically a bite plate (26). The bite plate has at least three fiducial markers on it. The fiducial markers may be LEDs (162), radiopaque markers for angiography, or computerized tomography (CT) imaging, or magnetic resonance markers for magnetic resonance (MR) imaging. By detecting the position of the markers, the position of features within the patient (such as a brain tumor) can be determined with great precision. Since the bite plate (26) has been molded to uniquely fit to the patient's teeth, it may be removed after an initial imaging of the patient. The bite plate (26) may then be reattached one or more times to the teeth. An alternate embodiment uses a head ring (18) or head holder such as a head mask system (276) with the LEDs thereon.

Abstract: An opto-electronic device utilizes a band of polychromatic light for quantitative analysis of a target molecule within a mixed specimen. A movable polarizes produces a segmented band of partially polarized polychromatic light firm the band of partially polarized polychromatic light. A specimen cell adapted for receiving the mixed specimen transports the segmented band of partially polarized polychromatic light to the mixed specimen. A movable polarizing analyzer is optically coupled to the segmented band of partially polarized polychromatic light exiting the mixed specimen. The segmented band of partially polarized polychromatic light before entering the mixed specimen is compared with the segmented band of partially polarized polychromatic light after exiting the mixed specimen. The movable polarizer is synchronized with the movable polarizing analyzer. Additionally a frequency filter can be optically coupled to the movable polarizer, where the frequency filter produces a beam of single frequency elliptically polarized light from the band of partially polarized polychromatic light such that the segmented band of partially polarized polychromatic light is a segmented band of elliptically polarized light.

Abstract: The present invention is an encrypting speech processor architecture that provides enhanced security without the use of external cryptosync and with minimal speech degradation. This is accomplished by incorporating a black encryptor (34) and a keystream generator (36) (instead of a fixed secret mask encryption scheme, such as those implemented in voice ciphers) for encrypting blocks of encoded speech bits at a transmitter side. The block encryptor (34) employs an invertible cryptographic algorithm and internal cryptosync to convert a first block of encoded speech bits into a first ciphertext block (output 34).  The first ciphertext block (output 34) is used to generate a keystream (output 36), which is then used to encrypt a second ciphertext block (FIG. 2).
