A skin incision device has a casing having a bottom surface with a slot formed therein, a cover positioned on the casing and slidable in a direction toward the bottom surface, a blade positioned in the casing adjacent the slot, an actuator cooperatively positioned between the cover and an interior of the casing, and a carriage element. The actuator engages the blade by its horizontal displacement triggered by the slidable movement of the cover toward the bottom surface of the casing. The carriage element guides the movement of the blade between a pre-actuated position and a post-actuated position. The blade moves outwardly through the slot, cuts with a horizontal movement, and returns inwardly through the slot.

A method for separating a thin glass sheet, such as a glass film along a predefined cutting line provides the cutting line immediately has a temperature of greater than 250 K below the transformation point Tg of the glass of the thin sheet of glass, including the input of energy along the cutting line using a laser beam which acts such that a separation of the thin glass sheet occurs.

A pane is separated from a moving ribbon of brittle material by restraining the ribbon upstream of a score line prior to separating the pane. The ribbon is restrained by selectively contacting a first side and a second side of the ribbon in one of an opposite, overlapping or offset relation. The ribbon can be restrained prior to, substantially simultaneous with or subsequent to forming the score line. The restrained status of the ribbon is maintained during and immediately after separation of the pane from the ribbon, thereby reducing the introduction of a disturbance or bending moment into the upstream ribbon.

An apparatus and methods are provided for monitoring a well and for obtaining fluid samples from below the ground. The apparatus includes a single-piece, extruded plastic well stock that extends from the surface of the ground to the lowest sampling depth. Plural sampling intervals are defined between the surface and the lowest sampling depth. Sampling intervals are defined by isolating sections of the borehole by using packers that seal the annular space between the well stock and the borehole. The well stock includes plural longitudinal chambers. Inlet holes are put into the well stock so that inlets for each interval admit fluid to only one longitudinal chamber. Inert sealant is injected below inlets to prevent fluid from spreading below a desired level. Instructions are placed into the longitudinal chambers to monitor fluids in the chambers or to retrieve samples, or alternatively, the well stock can be removed to obtain samples.

A digital-to-analog converter (“DAC”) system utilizes notch filters and chopping modulation technology to remove l/f and other baseband noise from a baseband of a signal of interest. Chopping modulation and demodulation circuitry of the DAC operate at a chopping frequency and all harmonics equal to approximately one-half of a digital input signal sampling frequency. A notch filter attenuates signals having frequencies around the chopping frequency prior to chopping to reduce fold back of noise into the baseband due to parasitic modulation. Another notch filter attenuating signals having frequencies around twice the chopping frequency further reduces fold back of noise into the baseband.

Selective Sharpening May Involve Sharpening Only Certain Portions Of an Image Or a certain percentage of the pixels of an image while avoiding over-sharpening already sharp areas and the introduction of signal noise in naturally uniform color and/or sharpness areas. A selective sharpening tool may selectively sharpen the image based on a user-indicated sharpening limit. For example, the user may select a particular portion of an image and specify that the least sharp 30% of the pixels in the selected image portion should be sharpened. In response, the selective sharpening tool may determine a sharpness value for each pixel in the image, rank each pixel based on its sharpness value and sharpen only the least sharp 30% of the pixels. Thus, a user may selectively sharpen a certain portion of an image (such as based on percentage of the pixels) while avoiding overly sharpening already sharp areas.

A sheet of brittle material is separated along a score line by applying ultrasonic energy to previously scored sheet material. The brittle material can be in the form of a moving ribbon, wherein a load is applied transverse to the score line to enhance crack propagation along the score line.

A skin incision device including a housing having a bottom surface with a slot formed therein, a top positioned on said housing and slidable in a direction toward the bottom surface, a blade pivotally positioned in the housing adjacent said slot, and a spring cooperatively positioned between said top and an interior of the housing. The spring is actuatable by the slidable movement of said top toward the bottom surface of the housing. The spring moves the blade between a pre-actuated position and a post-actuated position.

The present invention relates to methods, devices, a media signal and a recorded medium for watermarks embedded in the sub-band domain of compressed media. Watermarks (w[n]) are embedded into the sub-band signals (x_i−1[n], x_i[n], x_i+1[n]) of at least one selected sub-band of a compressed bit-stream (b_k) using a watermark inserting unit (18). In this way there is no need to fully decode and re-encode the media signal for embedding the watermark. The watermark is embedded in selected sub-bands (e.g. sub-bands 7-15 of 32). In a preferred embodiment, the selected sub-bands are upsampled before embedding and downsampled therafter to avoid aliasing. The invention also allows embedding multiple watermarks in different sub-bands (e.g. one watermark in sub-bands 7-11, and a different watermark in sub-bands 12-16).

To provide a manufacturing method for a silicon single crystal that can reduce introduction of dislocation thereinto even if a required amount of dopant is added to a melt while growing a straight body portion of a silicon ingot. In a manufacturing method for a silicon single crystal according to the present invention that includes a dopant addition step of adding a dopant to a melt while a straight body portion of a silicon single crystal is growing in a growth step of growing the silicon single crystal by dipping a seed crystal into a silicon melt and then pulling the seed crystal therefrom, in the dopant addition step, a remaining mass of the melt is calculated at the beginning thereof, and the dopant is added to the melt at a rate of 0.01 to 0.035 g/min·kg per minute per 1 kg of the calculated remaining mass of the melt.

A sheet of brittle material, such as glass, flat or bowed, is separated along a score line by applying fluid energy (compressed gas or liquid) through a fluid applicator such as a nozzle or directional fluid motivator, into a scored sheet material. A separation time of less than 1 second is possible with smooth edge quality. The brittle material can be in the form of a moving ribbon of glass sheet or a stationary sheet. A load (tension) can be applied transverse to the score line to enhance crack propagation along the score line. A controller controls the fluid pressure, release time and other process parameters for best results, depending on material properties and structure.

A first selection of mesh line segments of a mesh layer are of a first width and a second selection of mesh line segments of the mesh layer are of a second width, wherein the second width is greater than the first width. The second selection of mesh line segments of the second width are positioned in parallel to a selection of signal lines in a signal layer that are likely to introduce crosstalk, wherein the widening of the mesh line segments shadowing the selection of signal lines increases the likelihood that the return current associated with the signal will flow in the wider mesh line segment, thereby increasing the likelihood of containing the electromagnetic fields associated with the signal such that crosstalk to other signals is reduced or contained.

A boundary interpolation method is described for use with band offsets (BO) and largest coding units (LCU) within a video encoder. In BO, for example, very different offsets could otherwise be added to neighboring pixels which result in large discontinuities and visual artifacts. An interpolation, such as linear, is performed between the BO, or the periphery of the LCU, or a combination thereof, to smooth the offset function toward preventing introduction of visual artifacts.
