Abstract: The underside of an inactive portion of a display cover layer in an electronic device may be covered with an opaque masking material. Openings in the opaque masking material may be form ambient light sensor and proximity sensor windows. An ambient light sensor window may be filled with a material that transmits at least some visible light. A proximity sensor window may be filled with a material that transmits more infrared light relative to visible light than the material in the ambient light sensor window. The materials in the ambient light sensor window and proximity sensor window may include one or more layers of ink, patterns of holes, layers of material that are shared with the opaque masking layer, and materials that are black, white, or other colors. A light guide structure may be used to route light received from a sensor window to an associated sensor.

Abstract: A heater for preheating media in an imaging device including a substantially planar polymeric carrier having an exterior surface. A channel is recessed into the exterior surface of the carrier. A resistance heating element is disposed in the channel, the resistance heating element having a first and second end for coupling to a power source. The heater includes an over molded polymeric layer disposed in the channel such that the resistance heating element is substantially encapsulated in the channel and such that an exterior surface of the over molded layer is substantially flush with the exterior surface of the carrier.

Abstract: A stripper blade has been developed for high throughput inkjet printers. The stripper blade includes a metallic blade body having a first thickness that extends to a leading edge having a second thickness that is less than about 25% of the first thickness, and at least one beveled surface leading from the metallic blade body to the leading edge to form a stripping edge that facilitates separation of media from a drum.

Abstract: A mouth activated input device includes an elongated tubular body having an exterior surface, a first end and a second end. A first portion of the body at the first end has a first axis. A second portion of the body at the second end has a second axis, which is inclined at an angle to the first axis. A tongue activated multi-directional sensor element is positioned on the second portion. Either a bite switch, a sip and puff switch or both are incorporated into the body.
