Abstract: A mobile device mounting system includes a device case and a mount. The device case includes: an insert including a rectangular bore and defining a set of undercut sections about the rectangular bore; and a first set of magnetic elements arranged in a first pattern about the rectangular bore. The mount includes: a body; a polygonal boss extending from the body and configured to insert into the rectangular bore; a set of locking jaws arranged on the polygonal boss configured to transiently mate with the set of undercut sections to constrain the polygonal boss within the rectangular bore; and a second set of magnetic elements arranged in a second pattern about the polygonal boss and configured to transiently couple to the first set of magnetic elements to transiently retain the mount against the device case and to drive the set of locking jaws toward the set of undercut sections.

Abstract: A system and related methods of correcting errors during check or financial document processing by a bank of first deposit or other entity receiving a paper check or financial document, or by a second bank on whose accounts the checks were written. These corrections can be performed by the computer system of the bank of first deposit, the computer system of the second bank, or both. MICR data may be sent in electronic format from the bank of first deposit or other entity without qualification.

Abstract: An interface for an electronic device includes a plurality of function keys. Each function key has a distinct color different from other function keys in the plurality of function keys. The electronic instrument also includes a display. The display displays a plurality of soft key labels. Each soft key label is associated with and has a same color as one function key from the plurality of function keys. Coloring indicates to a viewer of the display associations between soft key labels and function keys.

Abstract: An n-port network analyzer system is calibrated. An initial calibration is performed for each test port in the network analyzer system by first performing a measurement calibration using calibration standards. The calibration standards are located in a reference plane located outside the network analyzer system. The measurement calibration yields initial calibration coefficients. The initial calibration coefficients include Forward Load Match (LMF) and Reverse Load Match (LMR). Electronic standards are measured within the network analyzer system to: produce initial measured electronic standards. The initial calibration coefficients and the initial measured electronic standards are used to generate initial corrected electronic standards. After the initial calibration, automatic re-calibrations are performed periodically. When performing the automatic recalibration, the electronic standards within the network analyzer system are measured to produce recalibration measured electronic standards.

Abstract: An input signal is mixed with sampling signals from oscillators which vary the frequency of the sampling signal from a first frequency to a second frequency. The resulting Intermediate Frequency (IF) signal is processed and digital values are stored in a memory in response thereto. Waveforms are then displayed which correspond to these frequency and amplitude values. Various input and display circuits facilitate the display and interpretation of these waveforms.
