摘要： A method, apparatus, and software for providing lifeline service during power failure affecting Customer Premises Equipment (CPE) in a Digital Subscriber Loop (DSL) arranged to carry voice traffic in band rather than on a separate analogue POTS band. The arrangement provides a reduced service, capable of supporting at least one voice call, to operate during such power failure and, where a single call is in progress during power failure, that call may be maintained during the transition from DSL to analogue POTS lifeline service. Where a call is in progress upon power restoration, the lifeline POTS service may be maintained until completion of the call so as not to interrupt a potential lifeline call.

摘要： Customer premises equipment for a telecommunications DSL subscriber is adapted to provide a lifeline voice service under a fault condition, e.g. a power failure at the subscriber station. The arrangement incorporates a number of switchable local subscriber ports each providing access to a respective telephone instrument, and a router circuit whereby, under normal conditions, voice calls may be routed each to a respective loop port. Under a fault condition the router directs an incoming call to a selected port to provide the lifeline service. Further calls may be barred when such a lifeline call is in progress.

摘要： The method of measuring a resonator such as a quartz crystal is to calculate its admittance from the voltage transfer function of a suitable network incorporating the resonator. This admittance can be expressed in the form of a circle. Two initial measurements are taken from which an approximate circle is calculated. This circle is used to calculate the optimum measurement positions for the subsequent curve fitting routines, those positions being symmetrically placed around the series resonance. Each measurement is an average of a number of samples. The deviation from this average as well as the deviation from the circle defined by previous measurements is used to monitor the measurement. All the parameters are calculated by least square curve fitting of the first the admittance circle and then the variation of phase around the circle with frequency.

摘要： A bluff body is placed in a fluid pipe with one flat face facing the oncoming fluid. Vortices are then generated and shed alternately from opposite edges of the body. This body is of a scalene triangle cross section, and in one version a hole extends transversely therethrough. A longitudinal hole intersects the first hole at right angles thereto. The vortices cause oscillations in the transverse hole. A light beam is provided in the longitudinal hole. The light beam is modulated as it crosses the path of the transverse hole. Hence by measuring the frequency at which the beam is modulated and by suitable calibration, one gets a good and reliable indication of fluid flow rate. In a second version the transverse hole is formed into a blind hole at the foot of which is an etalon (a Fabry-Perot interferometer). The effect of the fluid oscillations due to vortex generation influences the etalon so that its output is a measure of the fluid flow rate.

摘要： A fluid flowmeter of the vortex shedding type. The vortex frequency is determined from variations in the internal reflectivity of a prism 16 mounted in the fluid and coupled to a light source 13 and to a detector/frequency meter 14 via an optical waveguide arrangement 15. Passage of a vortex adjacent the prism 16 causes a temporary change in the local fluid refractive index and hence a change in the intensity of light internally reflected by the prism.

摘要： An optical fibre strain gauge arrangement is employed to take advantage of a so-called speckle effect. As used in a simple strain gauge, a coherent light source, e.g. a laser, launches light via a suitable launching device into a multimode optical fibre or fibre bundle. Due to slight differences in transmission times in the fibre or fibre bundle the light as received at a detector has a speckle pattern. If the fibre or fibre bundle is subjected to strain, the various transmission times are caused to change so that the speckle pattern shifts, the amount of the shift being a measure of the strain. This principle is usable in a vortex flowmeter where the vortices produced by a bluff body influence such a fibre arrangement. Further, when used underwater, passing ships and submarines may be detected. In a building, the arrangement may be used as an intruder detection system.

摘要： A vortex flowmeter having a double bluff body arrangement whereby vortices are generated at a rate corresponding to the fluid flow velocity. The upstream body and the downstream body together interact with the fluid stream to generate vortices. The arrangement introduces a relatively low blocking factor in comparison to simple bluff body arrangements. Vortex sensors are located between the bodies and downstream of the second body a distance between three and five times the diameter of that body.

摘要： In order to determine the vortex shedding frequency, from which the fluid flow rate may be calculated, an optical beam, such as produced by a laser, is passed through a fluid, transversely to a vortex street therein, and modulated in dependence on the alternate high and low velocity regions comprising the vortex street. The modulated signal is detected and "cleaned" of noise by filtering with a first (high) band-pass filter of a center frequency f.sub.c, such that the first filter output comprises an amplitude modulated signal of carrier frequency f.sub.c modulated by the vortex shedding frequency, that is the frequency of oscillation of the power spectra between the respective curves for the high and low velocity regions. The first filter output is demodulated and filtered by a second (low) band-pass filter, whose output is of a frequency comprising the vortex shedding frequency.
