Abstract: A calibration device is coupled to a communication line shared by plural devices. The calibration device is configured to perform an iterative eye width scanning by adjusting a set voltage level by a preset level from a first voltage level to a reference center voltage level, wherein the first voltage level corresponds to a cross point where values of signals or data, which are transmitted via the communication lines, are changed in different directions; and determine, as a zero crossing for the signals or the data, a voltage level corresponding to a largest value among a plurality of eye widths obtained through the iterative eye width scanning.

Abstract: A spectroscopy system that includes a light source that generates light having a plurality of wavelengths, a light transmitter that transmits the light to a target analyte, a light receiver that receives Raman-scattered light scattered from the target analyte, and a multi-wavelength spectroscopy assembly that acquires a spectrum by splitting the Raman-scattered light transmitted from the light receiver. The multi-wavelength spectroscopy assembly includes a single diffraction grating configured to diffract the Raman-scattered light and a single concave mirror configured to focus the Raman-scattered light.

Abstract: A portable information handling system user interface adapts based upon a position of a keyboard, such as a position detected by accelerations, Hall sensors, ambient light sensors and/or touchscreen display touches. In one example embodiment, a visual indication presented at a display aids end user location of a keyboard in a hidden position, such as a sliding keyboard disposed under a housing portion or a membrane keyboard integrated in a housing portion lower surface and exposed by a disconnect and flip motion.

Abstract: A portable information handling system applies context determined from sensors to selectively configure a display to present either a single user interface for a single user or two separate user interfaces for first and second users. For instance, detection of rotational portions in a flat orientation in proximity of multiple users results in a separate user interface at each rotational portion so that each end user has a user interface to interact with.

Abstract: A portable information handling system selectively attaches and detaches housing portions that each include a display for presenting information as visual images. The housing portions align in an attached state to present visual images at each display aligned with each other. Upon detachment, housing portion alignment is compared with each other to present each user interface aligned in a coordinated fashion at the displays by compensating for misalignment of the housing portions.
