摘要:
In embodiments of a touch-scrolling pad for computer input devices, a touch sensor strip detects touch contacts on a touch-scrolling pad that is implemented for vertical scrolling input and horizontal scrolling input. A selectable button positioned proximate below the touch sensor strip can be selected by an actuation depress input to the touch-scrolling pad. The touch-scrolling pad includes programmed instructions in firmware implemented to determine that a touch contact is one of a vertical scrolling input, a horizontal scrolling input, or the actuation depress input to actuate the selectable button. The touch-scrolling pad also includes a haptic system that generates haptic feedback responsive to either of the vertical scrolling input or the horizontal scrolling input.
摘要:
A measurement process or system transforms image data corresponding to images of an object to the frequency domain and analyzes the frequency domain data to determine a displacement of the object occurring between first and second images. Analysis in the frequency domain simplifies identification and handling of data expected to be noisy. In particular, frequencies corresponding to modes of vibration, lighting variation, or sensor error characteristic of a measurement system or frequencies corresponding to small magnitude frequency-domain data can be given little or no weighting in analysis that provides the displacement measurement. In one embodiment, Fourier transforms of shifted and unshifted images differ by a phase delay. A least square fit slope of the phase values associated with the phase delay can indicate displacements to accuracies less than 1% of a pixel width, thereby providing nanometer scale precision using imaging systems having a pixel width of about 1 μm.

A first device has a surface and includes a plurality of at largest micrometer-scale geometry structures extending along its surface. The structures have a first portion and a second portion. A plurality of at largest micrometer-scale geometry conductors are coupled to the first portion of respective structures. A converter converts a signal in the first portion of the structures to a substantially direct current signal in the respective second portion. A sensor detects a level of a signal coupled from one of the conductors to a respective one of the structures.

A first device includes a micrometer-scale or smaller geometry first conductor. A second device includes a micrometer-scale or smaller second conductor. An actuator the first and second devices relative to each other between first and second positions. Signals are substantially coupled between the first and second conductors in the first position and not in the second position.
摘要:
Measurement systems and methods extend the use of optical navigation to measure displacements smaller than a wavelength of the light used to capture images of an object measured. Nanometer-scale movements can thus be measured, for example, in equipment used for manufacture of integrated circuits or nanometer scale devices.

Using an imaging system in relation to a plurality of material layers in an initial alignment state is provided, a first of the plurality of material layers at least partially obscuring a second of the plurality of material layers in the initial alignment state. The first material layer is moved from a first position corresponding to the initial alignment state to a second position out of a field of view of the imaging system, and a first image of the second material layer is stored. The first material layer is moved back the first position to restore the initial alignment state. A second image of the first material layer is acquired. The second image and the stored first image are processed to determine the initial alignment state.

A printer having a transparency film discrimination system is disclosed. The printer includes a feed mechanism, an illumination source, a detector, and a processor. Light from the illumination source is reflected on or transmitting through the print medium (such as a transparent film) and is detected by the detector. The detected light is analyzed to determine the type of the medium. If the determined type of the print medium is not acceptable for the printer, then control signal is provided to the printer to halt the printing process as to avoid damage to the printer.
