Abstract: An electrophotographic photosensitive member includes a photosensitive layer of a single layer. The photosensitive layer contains a charge generating material, a hole transport material, an electron transport material, and a binder resin. An optical response time is 0.05 milliseconds or longer and 0.85 milliseconds or shorter. The optical response time is a time from irradiation of a surface of the photosensitive layer charged to +800 V with pulse light having a wavelength of 780 nm to decay of a surface potential of the photosensitive layer from +800 V to +400 V. The pulse light has an intensity that allows the surface potential of the photosensitive layer to decay to +200 V from +800 V after 400 milliseconds elapse from the irradiation of the surface of the photosensitive layer charged to +800 V with the pulse light. The photosensitive layer has a Martens hardness at 50° C. of at least 160 N/mm2.

The pivot supporting member includes a positioning member fitted on the supporting member from an end side and locked to the supporting member at a center side, and a fastening member fitted on the supporting member and the positioning member and fastened to the supporting member.

Abstract: Shooting sticks having pivotally attached support rests slidably attached to collapsible legs, said support rests providing a stable platform on which a user may aim and/or shoot a firearm or other object requiring at least temporary immobilization. A first channel running along the length of each support rests allows for the passage of a leg. A brake is attached to each support rest, said brake having an aperture through which a leg passes through, the aperture being configured, when the brake has not been depressed, to arrest any sliding movement of the support rest along the length of the leg to which it is attached. When the brake is depressed, the aperture becomes oriented perpendicular to leg which passes through it, allowing the support rests to freely slide up and down the leg. An elastic member provides an upwardly directed force to aid in support rest stabilization and lift assist.

Abstract: Line artifact reduction is provided in multi-beam scanning for Doppler imaging. An analytic solution uses estimated velocities for collocated receive scan lines from different transmit beams to reduce or remove the biases caused by multi-beam receive. For each location, a line or curve is fit to the estimated velocities as a function of distance of the transmit scan lines to the location. The velocity at an intercept of this line with the distance of zero (intercept with the origin) indicates the unbiased velocity. This approach allows a solution even where all of the velocity estimates have a bias with the same sign, such as due to the location being on a same side of the different transmit scan lines.

Abstract: Various technologies pertaining to a high-impedance current source are described herein. The current source outputs a substantially constant current by way of a first transistor that draws current from a supply. The current source is configured to feed-back noise from the supply to a feedback resistor at an input of an operational amplifier (op-amp) by way of a second transistor. The feedback resistor and the op-amp are configured such that responsive to receiving the supply noise feedback, the op-amp drives a gate voltage of the first transistor to cause the first transistor to reject the supply noise and cause the output of the current source to remain substantially constant.

Abstract: A camera device transmits a captured image and flow line information of moving objects to a server device for each predetermined transmission period. The server device generates a flow line analysis image in which the flow line information of the moving objects is superimposed on the captured image and displays the generated flow line analysis image on a display. The server device displays a first flow line analysis image generated based on a captured image and flow line information in a first period which is arbitrary designated, and receives an instruction by a user operation to shift the first period by an amount. The server device sets a second period by shifting the first period by the amount without changing a length in period, and displays a second flow line analysis image generated based on a captured image and flow line information in the second period.

Abstract: Disclosed is a calibration system and method for a phased array ultrasound pipe inspection system, in which reliable calibration is obtained for notches at all angles using only a small number of notches for the calibration. The method comprises a one-time normalization step and a system calibration step which may be performed at regular intervals. Ultrasound transmission is in a single diverging beam for each aperture, while reception is selective for multiple well-defined reception angles. During the normalization step, plots of maximum response vs reception angle are plotted for each notch, and a normalization curve is constructed by fitting the maxima of these plots. The normalization curve is used to derive calibration targets at specific reception angles for specific calibration notches, which are then used for the system calibrations.
