Patent EP-0503568-A2 (EP)
Inventor: HURST GEORGE S
IPC: G01T1/178
Filed: 1992-03-10
Abstract: A system for determining the health risk, due to alpha emitters attached to particles of various sizes, these alpha emitters being due to the level of radon, to persons within an environment where radon may be present. In one embodiment, a sample of air is passed through a filter element (32) having a collection characteristic such that essentially all particulate material, with their associated radon progeny, is removed from the air. The alpha particles emitted by the decay of these radon progeny are detected with an appropriate alpha particle spectrometer (40). The realtime resolving of the energies of individual of the daughter atoms permits a determination of the working level or PAEC associated with the radon. In those instances where lung dose is to be determined, the filter element has two portions. The first portion is designed to remove particles in a manner like that which occurs in the human nasal passage. The second portion of the filter element is designed to simulate the collection of particles by the lungs. An analysis of the energies of the alphas emitted from the radon progeny collected on the second portion is used to compute the lung dose. Either of the embodiments can be used to provide a signal that would be used for the operation of any radon mitigation equipment associated with the environment. Other uses for the resultant signals are discussed.

Abstract: A cable (20) includes a waterblocking member (29) which includes a superabsorbent polymer. The superabsorbent polymer includes an ionic constituent which is characterized in that its solubility product is substantially higher than that of carboxylate and in that it has a lower reaction rate for forming an anhydride than does carboxylate. The ionic constituent may be selected from the group consisting of sulfate, sulfonate and phosphate and also includes a counter ion. Other constituents may include a carboxylate and a non-ionic group constituent. The superabsorbent polymer is such that the amount of crosslinking is sufficient to avoid the polymer going into solution, but is not so much as to affect adversely the water absorbency of the waterblocking member. Further, the superabsorbent polymer is much more salt tolerant and temperature tolerant than are prior art superabsorbent polymers.

Abstract: A method and apparatus for measuring a base condition volumetric flowrate of a pipeline gas (14) flowing through a pipeline (16) in which a pipeline gas flowrate is measured by a pipeline gas flowmeter (22) that responds to density in a characteristic manner, a sample gas flowrate is measured by a sample gas flowmeter (10) that responds to density in the same manner as a pipeline gas flowmeter (22), and a base condition sample gas volumetric flowrate is measured by measuring the base condition energy flowrate of the sample gas (12), measuring the base condition heating value of the sample gas and dividing the base condition energy flowrate by the base condition heating value. The measured pipeline gas flowrate through the pipeline (16) is then adjusted by the ratio of the base condition sample gas flowrate divided by the measured flowrate of the sample gas (12). The temperature of the sample gas (12) should be substantially the same as the pipeline gas (14) in the pipeline when the sample gas flowrate is measured.

Abstract: A circuit for dividing a master clock by an odd integral value and producing a 50% duty cycle. A state machine develops set and clear signals which are of a timing proportion of n: n + 1, where 2n + 1 is the divisor value. The set signal is provided to one input of a bistable multivibrator or S-R latch to set the multivibrator to a given state, while the clear signal is combined with the master clock signal to delay or disable the clearing of the multivibrator by ½ count of the master clock, so that an n + ½: n + ½ proportion output clock signal is developed. Additionally, the circuit includes a state machine which determines which of a series of differing frequency master clock signals is active and when an external triggering event occurs so that the following rising edge of the output clock signal is delayed until a determined time after the triggering event to allow synchronization of the output clock signal.

Abstract: Optical metrology apparatus, specifically a laser probe (1) , includes a frame (10) comprised of a material selected to have a predetermined coefficient of thermal expansion. A beamsplitter (36) is coupled to the frame for generating a sample beam optical path (D) and a reference beam optical path (C). The beamsplitter is optically coupled to an optical fiber (12) that delivers radiation to and conveys radiation from the frame. A piezoelectric stack (48) has an excitation signal coupled thereto and includes a mirror (26) for phase modulating the reference beam optical path length in response to the excitation signal. The laser probe includes a first strain gauge (58) that is coupled to the piezoelectric stack and a second strain gauge (60) that is coupled to the frame. A closed loop control system (A1, A2, A3, A4, VR) varies the excitation signal in accordance with the detected strains so as to maintain the reference beam optical path length in a predetermined relationship to a path length of the sample beam optical path. This athermalizes the probe, in that any expansion or contraction of the frame is matched by the piezoelectric stack, yielding a net zero change in the non-common beam path lengths. The apparatus includes an optical fiber support (14) that is rotatably coupled to the frame for positioning the optical fiber at a desired angular position.

Abstract: The hitherto known devices for covering a window opening or door opening have the disadvantage that the covering element can be pushed upwards out of the unwound position by an unauthorized person, as a result of which this person can pass through the window opening or door opening into the interior of the building. This is avoided in that the device according to the invention exhibits, in the lateral guide rails, a rubber stop moulding and, opposite this, an expandable hose which, after the supply of compressed air, presses the covering element, e.g. an insect screen, fixedly against the rubber moulding. In order to supply the compressed air, a small pneumatic pump is provided on the inner side of the window. The device thus offers a high degree of protection against break-in since the insect screen has to be destroyed if an intruder wants to penetrate through the window opening or door opening located behind said screen. Moreover, it is ensured that even extremely strong gusts of wind cannot wrench the insect screen out of the lateral guide rails. <IMAGE>

Abstract: A telephone long distance service is provided using speaker verification to determine whether a user whether a user is a valid user or an impostor. The user claims an identity by offering some form of identification, typically by entering a calling card number on the phone's touch-tone keypad or by magnetic strip on the card which is read by the telephone. Unrestricted, extemporaneous speech of a group of customers are digitized, analyzed in accordance with a PCM circuit, and characterized as a non-parametric set of speech feature vectors. The extemporaneous speech of the long distance telephone service user claiming the identity of a service customer via his card number is digitized and analyzed in a like manner. The identity of the user is verified by comparing, either during or after the call, the signals in accordance with an algorithm which compares a reference utterance of a known customer with input utterances from one or more unknown telephone service users, one of which users has claimed the identity of the customer. This comparison results in a decision to accept or reject the hypothesized identity. The identity hypothesis to be tested is thus derived from the calling card of the customer.
