A dust cap adapted to fit within a fiber optic adapter. The dust cap includes a dust cap body having a back adapter end and a front knob end. The dust cap body is shaped such that the back adapter end has a press fit with a fiber optic adapter. An opening accommodates an adapter ferrule and a flange is secured in an adapter by a stabilizer and projection. The dust cap also transmits laser light along a longitudinal axis of the solid mass of the dust cap body from just beyond the back adapter end to just beyond the front knob end.

A fiber optic communications arrangement includes a closure with an interior volume; the closure including at least one cable through-port in communication with the interior volume; and an expansion component attached to an exterior portion of the closure and having an interior region in communication with the closure interior volume. The expansion component includes ruggedized fiber optic adapters mounted thereto. Each of the ruggedized fiber optic adapters includes at least one connector port for receiving ruggedized fiber optic connectors.

Example implementations relate to end-of-life determination for a print cartridge. For example, a print cartridge according to the present disclosure, may include a plurality of consumable components. Each of the plurality of consumable components may have an associated sensor to monitor use of the respective consumable component. The print cartridge may further include a memory including instructions executable by a processor to, for each of the plurality of consumable components, receive a past use value quantifying an amount and type of use of the respective consumable component, determine an end-of-life value for the respective consumable component using the past use value and a predetermined tuning factor for the respective consumable component, and determine an end-of-life value for the print cartridge based on the plurality of end-of-life values for the plurality of consumable components.

A machine-implemented method for computerized digital signal processing including obtaining a digital signal from data storage or from conversion of an analog signal, and determining, from the digital signal, one or more measuring matrices. Each measuring matrix has a plurality of cells, and each cell has an amplitude corresponding to the signal energy in a frequency bin for a time slice. Cells in each measuring matrix having maximum amplitudes along a time slice and/or frequency bin are identified as maximum cells. Maxima that coincide in time and frequency are identified and a correlated maxima matrix, called a 'Precision Measuring Matrix' is constructed showing the coinciding maxima and the adjacent marked maxima are linked into partial chains.

Precision measurement of waveforms

The invention consists of new ways of constructing a Measuring Matrices (MMs) including time deconvolution of Digital Fourier Transforms DFTs. Also, windowing functions specifically designed to facilitate time deconvolution may be used, and/or the DFTs may be performed in specific non-periodic ways to reduce artifacts and further facilitate deconvolution. These deconvolved DFTs may be used alone or correlated with other DFTs to produce a MM.

Precision measurement of waveforms using deconvolution and windowing

A machine-implemented method for computerized digital signal processing obtains a digital signal from data storage or from conversion of an analog signal and determines, from the digital signal, Measuring Matrices (MM). Each measuring matrix has a plurality of cells, each cell having an amplitude corresponding to the signal energy in a frequency bin for a time slice. Cells in each measuring matrix having maximum amplitudes within a time slice are identified as maximum cells. Maxima that coincide in time and frequency are identified and a correlated maxima matrix (PMM) is constructed showing the coinciding maxima and the adjacent marked maxima are linked into partial chains. If only one MM is constructed, multiple types of maxima are identified to generate the (PMM). The partial chains are isolated by parameters for a single domain or multiple domains to identify partial chains and possible separation of complex compound waveforms in the digital signal.
