摘要： Architecture for a keyboard that supports the n-key rollover feature, while being compatible with well established, high volume, inexpensive manufacturing techniques. The design is a matrix design that uses resistors at each key rather than diodes, and employs novel circuits which allow any combination of simultaneous key presses to be detected using this resistive matrix. The resistors can be screen printed on the flexible sheets in a manner similar to the conductors. A resistive keyboard matrix employs circuit techniques that eliminate phantom key presses. The resistors can be created by screen-printing carbon ink. Additionally, various implementations of the decoder circuits can be employed to provide the n-key rollover feature on flexible sheets for inexpensive production.

摘要： An apparatus measures a fluid level in a container. A light source emits a light beam. A light sensor can sense the light beam. An optical conduit is arranged in a container for holding fluid. The optical conduit is arranged between the light source and the light sensor along a path of the light beam, such that at least one part of the light beam passes through the optical conduit, and at least an other part of the light beam passes through the fluid when the container holds the fluid. The sensor senses the light beam when a level of the fluid coincides with the one part of the light beam passing through the optical conduit, and the sensor does not sense the light beam when the level of the fluid coincides with the other part of the light beam passing through the fluid due to internal reflection at the fluid level.

摘要： A user interface is configured to detect an attempt to touch a virtual button. The interface includes a first concave mirror facing a second concave mirror. The second concave mirror includes an aperture. A physical control button is arranged proximate to the first mirror and aligned such that an image of the control button in a form of a virtual button appears at the aperture. An attempt to touch the virtual button is detected, and feedback is generated at the virtual button in response to detecting the attempt to touch the virtual button by a user.

摘要： Techniques are described for providing a cleaned signal in a capacitive touch sensor. A phase of periodic noise on an input of the capacitive touch sensor is determined, and a periodic excitation signal having a phase that is locked to the determined phase of the periodic noise is generated. The periodic excitation signal is applied to an excited conductor in a first array of the touch sensor. While the excitation signal is applied, a response signal on a responding conductor in a second array of the touch sensor is detected, and, based on the detected response signal, a value indicative of a measured capacitance between the excited conductor and the responding conductor is generated. A threshold value is accessed, and a determination is made whether the response signal corresponds to a touch based on a difference between the value and the threshold value.
