    Abstract: The present disclosure proposes a design of a biomedical paper sensor which can determine the concentration of biological materials in fluids such as blood, urine, and saliva. The sensor contains a plurality of axially radiating test zones, each test zone separated from other test zones by wax ink barriers formed by a process that produces thin walls. Each test zone can contain a unique test reagent, or a unique concentration of a test reagent, and can also be identified by printed text. The region of the device outside of the test zone area is printed with a uniform reference color. Benefits of the invention include increased accuracy in the measurement of the concentration of biological materials due to the larger test zone area. Benefits also include the integration of the reference or calibration color which simplifies the calibration needed for quantification of the concentration.

    Abstract: An image forming apparatus including an electrophotographic photoconductive member, a charging unit, a delivery unit and a cleaning unit. The charging unit is disposed in contact with the surface of the photoconductive member and the delivery unit disposed in contact with the surface of the charging unit. The delivery unit applies a layer of functional material to a surface of the charging unit and the charging unit in turn applies a layer of the functional material onto the surface of the photoconductive member. The cleaning unit is disposed in contact with a surface of the charging unit to clean the charging unit and reduce contamination of a surface of the delivery unit. The cleaning unit is disposed in an upstream direction of the delivery roller relative to a rotation direction of the charging unit.

    Abstract: There is described an image forming apparatus including an imaging member having a charge retentive-surface for developing an electrostatic latent image thereon, a substrate and a photoconductive member disposed on the substrate. A bias charge roller for applying an electrostatic charge on the charge retentive surface to a predetermined electric potential is included in the image forming apparatus. The bias charge roller includes a first circumferential area in contact with the photoconductive member (CC[contact]), and a second circumferential area (CC[non-contact]) spaced a distance of from 1 μm to 1 mm from the photoconductive member. The image forming apparatus includes a power supply for supplying an oscillating voltage signal to the bias charge roller wherein the oscillating voltage signal has a frequency Am[fAC] and an amplitude Am[VAC]. The following relationship is met: (CC[contact]/CC[non-contact])≦(Am[fAC]/Am[VAC])≦(CC[non-contact]/CC[contact]) by the image forming apparatus.
