    摘要: A pressure sensor is provided which can detect the presence, absence or magnitude of pressure, as well as a pressure profile. The pressure sensor includes a sensor membrane and a sensor device. The sensor membrane is flexible and may be constructed of a conductive material or may include a flexible film attached to a conductive film. The sensor device includes a sensor strip, a voltage source, and an electrical sensor. The sensor strip includes both a conductive strip and a resistive strip. The conductive strip is arranged parallel to the resistive strip. As pressure is applied to the sensor membrane, the sensor membrane distends or deforms towards the sensor strip. As sufficient pressure is applied, the sensor membrane will make both electrical and mechanical contact with both the conductive strip and the resistive strip at a point along the length of the sensor strip. Since the sensor membrane is conductive, the conductive strip and the resistive strip will be in electrical connection with each other. As the point of application of pressure is varied, the point at which the conductive strip and the resistive strip are connected will vary. As a result, the pressure profile exerted on the sensor membrane may be determined. The pressure sensor may be utilized in a variety of environments to sense a wide variety of pressures including either fluid pressure or physical contact pressure.

    摘要: An apparatus and method for measuring and monitoring layer properties in web-based processes are described. The apparatus includes multiple electrode devices adjacently positioned on a surface of a web material, which advances with a predetermined speed. The electrode devices perform measurements of electrical parameters of a layer of the web material and provide an electrical signal to a layer deposition system for further adjustment of layer properties of the layer.

    摘要: A tactile display has a contact surface that has multiple addressable pixels. Each pixel has a vibration element that is energizable to vibrate at a selected frequency and amplitude. The vibration of selected pixels of the tactile display provides tactile feedback to a user's finger touching the contact surface.
