A stable topical alcohol-free aerosol foam containing one or more keratolytic agents is provided. The foam-forming formulation is an emulsion which contains an HFA propellant and one or more keratolytic agents. The emulsion has an oil phase and an aqueous, i.e. water-containing, phase. The active agent(s) may be present in either phase of the emulsion or dispersed in the emulsion. The oil phase may consist at least in part of the HFA propellant. Either or both of the oil phase and the aqueous phase may contain one or more surfactants, emulsifiers, emulsion stabilizers, buffers, and/or other excipients. The foam is stable on the skin, for example, for at least 5 minutes at body temperature, preferably at least 20 minutes at body temperature, and disappears into the skin upon rubbing or after prolonged standing. In one embodiment, the formulation contains an HFA propellant which does not contain additional co-solvents or co-propellants. The formulations demonstrate reduced intensity of the odor and/or color associated with the keratolytic agent(s) as compared to conventional formulations containing keratolytic agents.

A motor vehicle lighting system comprises a lighting switch having a daylight signaling position and two night driving illumination positions, with a running light (or headlight) having a discharge lamp cooperating with a reflector to produce a night driving beam essentially without any cut-off. The running light has a discharge lamp cooperating with a reflector to produce a night driving beam which essentially has no cut-off. The system includes a means such as an absorbent element which, when the lighting switch is put in its daylight signaling position, diverts a fraction of the light intensity of the emitted beam so as to produce a beam of reduced intensity as compared with the same lamp powered under the same conditions.

A lamp assembly adapted to cast shadow-free illumination over an area. Typically, a lamp assembly includes a plurality of light modules that are disposed in a spaced apart relationship over an area. The lamp assembly can be arranged to focus light from the lamp to a central area of illumination of high intensity, with significantly reduced intensity illumination outside the central area.

An intraoral discluder for preventing chronic tension headaches, common migraine headaches, and temporomandibular disorders that are caused or perpetuated by chronic activity of the temporalis muscle. The discluder includes a trough, contoured to encompass at least one maxillary or mandibular incisor, from which extends a protruding platform, for engagement by the opposing incisors. The trough can be retained on the teeth by any adaptable material than can flow around the teeth and then maintain its shape. Once in place in the wearer's mouth, one or two opposing incisors will come into contact with the platform prior to the upper and lower posterior and/or canine teeth coming into contact, regardless of the position of the mandible, thereby reducing the intensity of the activity of the temporalis muscle. In addition, a special post on the discluder's platform is engageable directly with one or more opposing incisors, to act as a stop and thereby inhibit excessive retrusive movement of the mandible and urge the mandible toward a more protrusive position. This can reduce the intensity of undesired clenching, and it can enhance the size of the wearer's pharyngeal airspace, thereby reducing the incidence and severity of snoring.

A method of performing manufacturing operations on a workpiece made of a high strength alloy is disclosed in which a local area of a workpiece is heated to micro-structurally soften the local area. The local area of the workpiece becomes softened and more ductile. A manufacturing operation involving deformation of the heat softened area is performed with the metal in the heat softened region being more ductile and having less strength than the surrounding portions thereof. Manufacturing operations may include riveting, clinching, hydro-forming, and magnetic pulse joining.

A method and apparatus where the output from a high intensity light source is controlled to produce well-exposed images/videos and to reduce automatically the intensity when an unsafe issue is detected in medical devices such as endoscopes and the like. The method and apparatus overcome problems to control light sources that have high-frequency noise, slow-response time, nonlinearity, and non-monotonic response time and to protect the patients' tissues from possible overheating/burning and the eyes of personnel and patients from possible direct exposure to high intensity light used in medical devices such as endoscopes and the like.

A 3D projector system includes a locally modulated polarizer mounted in front of a projector. The polarizer is controllable to produce different polarization states for local regions of the projector images. Combinations of polarizer states and projector images can be used to produce left and right images which have reduced intensity differences between subsequent frames. This may reduce flickering and viewer eye fatigue. This may also reduce unwanted crosstalk between left and right eye viewpoints and increase image contrast and dynamic range.

A method for compressing an intensity dynamic range of an input image to a reduced intensity dynamic range of an image display device includes defining a plurality of units of the input image, determining a local mean estimate of an intensity of each of the plurality of units of the input image, generating a contrast modification processing value for each local mean estimate, and generating an output intensity value, for each local mean estimate, by using only the generated contrast modification processing value and an input intensity value.

Advantage is taken of the fact that in optical navigation devices it is possible to measure the intensity of light impacting the pixel array of photo-diodes. Based upon such an intensity determination, a feedback signal is used to reduce the intensity of the light to a point where it is equal to or less than a predetermined value. In one embodiment, the discharge rate of a capacitive power supply is used to determine the intensity of the light source impacting the pixels. When the discharge rate is faster than a given amount the inference is that the light intensity is too great and power is reduced to the light source to reduce the intensity.

The invention provides a construction method of watery red sandstone geological underground water level control. The construction method is characterized by comprising the following steps: 1) construction preparation; 2) deepening design and optimization of a light well point precipitation scheme; 3) installation of a plurality of light well point precipitation devices; 4) running of a vacuum pump, debugging and pumping, and pumping running; 5) layered earthwork excavation and layered precipitation; 6) reducing a cushion layer by several times, reducing a branch pipe and re-debugging the pumping; 7) closing the cushion layer, and continuously precipitating; 8) stopping precipitation of light well point precipitation devices. Specific to the characteristics of high underground water level and big water content of red sand rock, the construction method can well control the excavation depth of every layer in case of softened red sand rock, reduced intensity and disintegrated earthwork for the seepage of underground water since the precipitation is not timely.

This disclosure includes an imaging system that is configured to image in parallel multiple focal planes in a sample uniquely onto its corresponding detector while simultaneously reducing blur on adjacent image planes. For example, the focal planes can be staggered such that fluorescence detected by a detector for one of the focal planes is not detected, or is detected with significantly reduced intensity, by a detector for another focal plane. This enables the imaging system to increase the volumetric image acquisition rate without requiring a stronger fluorescence signal. Additionally or alternatively, the imaging system may be operated at a slower volumetric image acquisition rate (e.g., that of a conventional microscope) while providing longer exposure times with lower excitation power. This may reduce or delay photo-bleaching (e.g., a photochemical alteration of the dye that causes it to no longer be able to fluoresce), thereby extending the useful life of the sample.

The invention belongs to the technical field of mechanical structure design, and relates to a method for manufacturing a wedge block having the same length of curves of each cross section. The methodselects n planes on the wedge block, calculates a difference value of the length of the curves around the cross section through CATIA software, compensates the difference value of the length of the curves around the cross section by using the height difference, and reconstructs an entity with the same length of the curves around the cross section. By using the structure, when carbon fibers are wound around the wedge block, wrinkles do not occur due to the same length of the curves around the cross section; the reduction of strength caused by loosening of an internal structure is avoided, the damage during operation is reduced, and the service life of blades is prolonged.

The invention discloses a neutron shielding protection material. The material comprises a base layer prepared from pure boron carbide materials and is characterized in that a surface layer with the thermal conductivity rate higher than that of the base layer is formed on and bonds with the surface of the base layer. The base layer is prepared from the pure boron carbide materials, a good neutron absorption shielding effect can be ensured, due to the fact that the surface layer with higher thermal conductivity rate is formed on and bonds with the surface of the base layer, the surface layer with higher thermal conductivity rate can be utilized to conduct and dissipate heat of the base layer to the outside, and it can be avoided that the performance of the base layer is reduced due to the excess temperature. The material has a good neutron absorption shielding effect and a good high-temperature resistance effect, a thermal throttling mode is adopted, the self-heat-dissipating effect of the material is improved, and it is further avoided that due to the excess using temperature of the material, the thermal ageing phenomenon is worsened, the mechanical property is reduced, and the reduced intensity causes cracks.

An optical perturbation sensing system includes a probing beam incident on a medium with perturbations and a sensing beam redirected from the medium and incident on a surface area of a photodetector. A reference beam directed onto the photodetector surface forms, with the sensing beam, an interference pattern on the photodetector surface and a phase patterner with at least two phase regions across its section, generates different phases in different regions of the interference pattern. An array of photodetector elements detects each phase region of the interference pattern and a constructive combiner subtract pairs of the detected signals, squares the subtracted signal squares, and sums the squared signals to form a stronger detected signal with reduced intensity noise, reduced background noise, and reduced sensitivity to phase drifts.

A method and system for enhancing the grayscale resolution of display systems using 8-bit imaging arrays. The grayscale resolution is increased by providing a resolution greater than 8 bits. The on-time for each shade is subdivided in two sub-frames. During a first subframe, a full intensity light source is turned on and the imaging array processes five most significant bits of data, while least significant bits are stuffed with zeros. During a second subframe, the light source is turned on at reduced intensity and the imaging array processes the three least significant bits, which are left-shifted. The data byte for the second subframe is filled out using Digital Signal Processor (DSP) data obtained by over-sampling or interpolation. The lower order bits may be also stuffed with zeros.
