Patent EP-0822401-A2 (EP)
Inventor: BEHRINGER BRUCE E
IPC: G01N35/08
Filed: 1997-07-18
Abstract: An optical illuminator assembly for an analytical instrument, such as
a clinical hematology or a flow cytometer instrument, and method of aligning
the components of the illuminator assembly and orienting the illuminator
assembly. The illuminator assembly includes a plurality of optical
components, such as a laser source, e.g., a laser diode, optionally a spatial
filter, a beam shaping aperture, and a focusing lens. The optical components
are mounted in or to a housing and are internally oriented with respect to the
housing to produce a focused laser beam output. The housing is in turn
mounted on an alignment mechanism which can move the focused beam in
four degrees of freedom, thereby to direct the focused beam to a particular
location. Thus, a factory alignment and a low cost prealigned optical
illuminator assembly is obtained, which can be easily oriented for use in an
instrument.

Abstract: A secret communication and authentication scheme based
on a public key cryptosystem in which a decryption speed is
improved while maintaining a security level. In the RSA
type secret communication, a plaintext is expressed in a
form of a k-digit n-adic number and a ciphertext is
obtained by applying a calculation using the first public
key n and the second public key e to the n-adic number and
transmitted. Then, from the received ciphertext, a lowest
digit of the n-adic number is decrypted by using the first
public key n and the second secret key d, upper digits of
the n-adic number are sequentially decrypted by using a
decrypted value of the lowest digit of the n-adic number at
the receiver side, and the plaintext is recovered by using
decrypted values of respective digits of the n-adic number.
The Rabin type secret communication can also be realized by
the similar scheme. Moreover, the same principle of the n-adic
pubic key cryptosystem can also be used in realizing
the RSA type or the Rabin type Authentication.

Abstract: The transverse dynamics regulation method uses a tyre model for determining the actual adhesion of the vehicle tyres in the transverse and longitudinal directions for calculation of a required transverse acceleration, compared with the actual transverse acceleration to provide a correction factor (F). The correction factor (F) is used for correcting the actual adhesion of the vehicle tyres by controlling the vehicle brakes, or adjusting the throttle setting element for the vehicle engine, to obtain the required transverse adhesion.

Abstract: A wavelength conversion apparatus has an optical
amplifier, a wavelength converter, and an optical coupler
coupled to form an optical ring resonator. The optical
amplifier supplies pump light. The wavelength converter
generates converted light, either from the pump light alone
or by interaction between the pump light and signal light
supplied from a signal source. The optical coupler extracts
the converted light. The optical ring resonator preferably
includes a tunable optical bandpass filter that defines the
wavelength of the pump light. The optical coupler may also
couple the signal light into the optical ring resonator,
preferably through a polarization beam splitter and at least
one polarization rotator, making the apparatus insensitive
to the polarization of the signal light.

Abstract: A separating closure liner comprises a laminate
construction of a reusable liner portion and an inner
seal portion, each separated by a light tack shearable
adhesive. The light tack shearable adhesive enables the
reusable liner portion to break away from the inner seal
portion after it has been sealed to a container neck.
The reusable liner portion remains in the closure of the
container for sealing purposes. Use of the light tack
shearable adhesive permits the use of polyolefin foamed

Abstract: A rotary machine has two rotors 16,18 mounted for rotation
on parallel axes, each in one of two intersecting
cylindrical chambers 12,14. The rotor 16 has a hub 24 and
a flap 26 extending radially from the hub into close
proximity with, but not into contact with, the cylindrical
wall of chamber 14. The rotor 18 has a hub and a radial
recess 30 which accommodates the flap 26 as the rotors
rotate. The rotors are linked to one another so that they
rotate at the same angular speed but in opposite angular
directions. The flap 26 divides the chamber 14 into two
volumes, one either side of the flap. Working fluid is
introduced through the first rotor and passes along a
radial passage through the rotor to direct incoming
working fluid from one side of the flap into a volume on
one side of the rotor. The working fluid can be provided
from an external combustion chamber.

Abstract: A cosmetic container for a cosmetic, such as lipstick, which permits the cosmetic to be extended and retracted for application and which permits a low swivel torque, which operates smoothly, and which substantially minimizes or prevents "push-back". The container includes a uniquely configured lug (24) which cooperates with a helical channel (42) of a tubular sleeve (40) to prevent push-back which is defined as unwanted movement of the lipstick within the container caused by downward axial force which results when the lipstick is applied. According to one embodiment, the lug (24) includes an end surface portion (58) having a compound surface wherein one portion thereof is parallel to the longitudinal axis and another portion thereof is positioned at an acute angle to the longitudinal axis. The compound surface also includes a line of intersection (64) defining the portions which is, itself, angularly positioned relative to a plane normal to the longitudinal axis. The compound surface abuts either an inner surface the tubular sleeve (40) or a sidewall of the helical channel (42) when downward axial pressure is applied to the lipstick and the carrier supporting the lipstick. According to an alternative embodiment, the lug end surface portion (58) includes a convex protrusion (74) and the helical channel (42) includes a correspondingly configured concave portion to receive the convex protrusion.

Abstract: An eyesafe laser system (2) includes a Q-switch crystal (20)
formed of a semiconductor host material having noncentrosymmetric
tetrahedral substitutional sites doped with transition
metal ions in concentrations from about 0.001 to about 0.10
atomic percent, which functions as to be a saturable absorber
of light at eyesafe wavelengths with a relatively long relaxation
lifetime. Co 2+ :ZnSe has been demonstrated to have advantageously
high relaxation lifetime at both 1.54 µm (Er:glass laser)
and 1.64 µm (Er:YAG laser). Other candidate host materials
include other zinc chalcogenides, cadmium chalcogenides and
zinc oxide. The resultant Q-switch (20) does not require additional
focusing optics inside the cavity (4) and has a saturation
fluence which is approximately one order of magnitude less
than other state of the art saturable absorbers in the
"eyesafe" wavelength region, thereby permitting substantially
faster Q-switch bleaching, lower thermal loads, and less potential
for damage than was hitherto possible.
