Abstract: A method and apparatus for analyzing a fluid containing light scattering components. The
apparatus includes a laser adapted to direct a beam of light into the fluid such as a liquid containing
particles, and at least two detectors to receive light scattered by the fluid, which received light is
used to calculate a physical property of the fluid. A focusing lens may be used to focus the light
beam to a focal waist in the fluid to enhance the degree of spatial coherence of the scattered light.
The two detectors are aligned onto the focal waist and are adapted to send a signal to a data
processor which correlates the signal received from said two detectors. The two detectors are
spaced a substantially equal distance from the focal waist and are oriented at substantially the same
angle with respect to the direction of propagation of the incident beam. The data processor is
adapted to cross-correlate the signals received from the two detectors. A polarizer can be
positioned between the focal waist and the two detectors to aid in positioning the detectors and to
enhance the efficiency and speed of the measurement.

Abstract: The bobbin winder assembly has the yarn guide (18,21), the bobbin clamping plate (2) with the catch slit (4) and the suction unit (37) in an array so that the yarn (1) is on an angled path over the edge (6) of the clamping plate towards the bobbin sleeve (13) on the direction of clamping plate rotation. The plate edge has a yarn catch projection (5), and a cutback recess (7) of the catch slit which, with the edge of the clamping plate, form a yarn guide edge (9). The guide edge extends against the direction of rotation to an entry plane, so that the yarn is moved along the inner surface (15) of the plate into the clamping slit (14) through the clamping plate rotation. The yarn guide (18,21) moves parallel to the rotary axis of the bobbin sleeve, with the guide (18,21), sleeve clamping plate and suction unit in sequence along the line of yarn travel. The guide edge (9) has a spiral shape towards the sleeve edge (17). The clamping slit (14) is formed by a recess (12) in the centering shoulder (8) of the clamping plate and the sleeve edge. The recess has a radial angled clamping flank (16), tapering down below the sleeve edge, so that the clamping slit has an increasing width in the direction of the sleeve (13) rotation. On an axial section, the recess has a turned-in L-shape, extending over an arc of the smaller dimensions. The recess extends over the centering shoulder (8) by an angle of 60-120 degrees , so that the cutout (7) in the end edge (6) and the recess (12) in the centering shoulder overlap. The catch slit (4), at the clamping plate (2), is offset axially away from the sleeve center in front of the clamping slit, in the direction of rotation, into the entry plane. The cutter (45) is between the suction unit (37) and the sleeve clamping plate, so that the caught yarn (1) is drawn into the cutter by the catch projection (5), through the rotation of the clamping plate (2). The cutter has an entry edge with a blade at its end shortly after a step. A sensor (32) monitors the position of the catch slit (4) at the clamping plate connected to the control (27) for the movements of the yarn guide. The sensor (32) is a pulse generator, to deliver a pulse to the control on each rotation of the clamping plate. The control evaluates the number of pulses in a time unit, to calculate the sleeve rotation speed. The yarn guide is a reciprocating guide (21) at a reciprocating movement system, to move the yarn to and fro along the length of the sleeve to carry the wound yarn as a bobbin, and outside the length of the windings. The yarn guide speed is set through a variable drive, independent of the movement direction.

Abstract: A power diode is provided with regions of semiconductor material of high lifetime and
low lifetime. For high frequency operation, low lifetime material is preferable, but this
can result in undesirable transient current and voltage spikes. The regions of different
lifetime material are spaced apart in a direction parallel to the p-n junction of the diode,
and in embodiments of the invention are arranged to intersect the junction. Several
configurations are described which produce different voltage-current transfer
characteristics in which the effect of unwanted transient signals is reduced.

Title: Reducing cache misses by snarfing writebacks in non-inclusive memory systems
Inventor: HAVES NORMAN M
IPC: G06F12/08
Filed: 1998-09-18
Abstract: The present invention is a method and apparatus for optimizing a non-inclusive
multi-level cache memory system. Cache space is provided in a first cache by removing
a first cache content, such as a first cache line or block, from the first cache. The
removed first cache content is stored in a second cache. This is done in response to a
cache miss in the first and second caches. All cache contents that are stored in the
second cache are limited to have read-only attributes so that if any copies of the cache
contents in the second cache exist in the cache memory system, a processor or
equivalent device must seek permission to access the location in which that copy exists,
ensuring cache coherency. If the first cache content is required by a processor such as
when a cache hit occurs in the second cache for the first cache content, room is again
made available, if required, in the first cache by selecting a second cache content from
the first cache and moving it to the second cache. Once room is available in the first
cache, the first cache content is moved from the second cache to the first cache,
rendering the first cache available for write access. Limiting the second cache to read-only
access reduces the number of status bits per tag that are required to maintain cache
coherency. In a cache memory system using a MOESI protocoal, the number of status
bits per tag is reduced to a single bit for the second cache, reducing the tag overhead.
An optimization advantage in that the tags may be placed on-chip so as to improve
cache bandwidth.

a distance between the distal most tip of the lead body and an
electrode for a distance of approximately 3cm
and has the greatest flexibility of any
of the remaining linear section. A middle lead
body portion (201) extends from the first electrode to a second
electrode for a distance of approximately
1.5 cm, and this section has the greatest flexibility
of any of the other remaining linear section of the lead body
(i.e. it is less flexible as compared to distal section). Next a
further section (202) of the lead features a tine (102) having an
electrode, this section is positioned from second electrode a
distance of approximately 5cm.
This section has the least flexibility of any of the sections of
the lead body.

Abstract: The invention relates to modified recombinant allergen mutants which can be obtained from recombinant allergens derived from allergens obtained by means of extraction from natural raw materials, such as the pollen of the species Phelum pratense. These modified recombinant allergens stimulate the lymphocytes of persons suffering from a pollen allergy to bring about proliferation and cytokine synthesis, but have a significantly reduced capacity to bond with the IgE antibodies contained in the serum of lymphocyte donors and with grass pollen allergen specific IgEs. The inventive modified recombinant allergens can therefore be used for a specific, individual allergy treatment.

Abstract: A data browser is described for accessing data defining virtual environments via the Internet/World Wide Web. Where the data defining objects to appear within the virtual environment is in the form of discrete geometrical components, with each object being arranged as a hierarchy linking the components and with transformations (T0, T1, T2, T3) specifying the translation of vertex locations for a child component to the coordinate system of its parent, the browser maintains a record of previously calculated transformation products (T0. T1). Each time the browser updates its generated representation of the virtual environment it checks which components have moved, and hence which transformation multiplications must be updated, and otherwise recalls the result of the previous calculation.

Abstract: In a telephone exchange the functional units of call control communicate by way of a common message bus. If a unit wants to know only one thing from the data of a message, then due to the fixed structure of the message all other data contained in the message must also be received. Unnecessary data is thus transmitted in the message bus. The procedure according to the invention is such that the service requester states in the request message exactly what it wants to know. Since the data structure of the service provider, that is, the position of each individual data and the length of the data field, is known to the service requester, only those entries of the data structure are stated in the request message where the requested data is located. The service provider fetches only this data from its data structure and sends it in the reply message to the message bus. Thus, both the request message and the reply message form a dynamic message pair.
