Abstract: The present disclosure is drawn to printhead assemblies including an encapsulating layer. For example, a printhead assembly can include a first printhead including a first array of dispensing nozzles and a second printhead including a second array of dispensing nozzles. The first and second array of dispensing nozzles can be positioned along an ejection surface of the printhead assembly.

Abstract: Apparatus for processing broadband impulses signals of low repetition rate includes a tuner for receiving broadband impulsive signals of low repetition rate and providing an output signal characteristic of the amplitude and spectral content of the received input signal. Resolution bandwidth filters coupled to the tuner output each have a different bandwidth that determines the measurement resolution and influences the sensitivity and transient response to low repetition rate impulsive signals. At least one radio frequency switch selects a resolution bandwidth filter for coupling to and associated one of at least a peak detector, an average detector and an envelope generator. A gate generator coupled to the peak detector, the average detector and the envelope generator furnishes a gating signal to each to provide a peak signal, an average signal and an envelope signal respectively during a selected gating interval. A microprocessor is coupled to the peak detector and the average detector.

Abstract: Print heads and print head fluids are disclosed. An example print head for an inkjet printer system includes a fluid reservoir, and a nozzle fluidically connected to the fluid reservoir. The example print head also includes a fluid having a liquid vehicle component and a tinting dye. The fluid is provided in the fluid reservoir during shipping of the print head to maintain wetting of the print head. The fluid is discharged after installation of the printer head in the inkjet printer system.

Abstract: An automatic power control system for automatic power control of a semiconductor optical amplifier arranged to amplify a signal has an automatic power control loop which provides automatic power control of the power of the amplified signal for maintaining the power of the amplified signal in the output from the semiconductor optical amplifier at a desired level. The automatic power control loop compensates for, an estimated level of amplified spontaneous emission in the detected output power using stored characteristics of the semiconductor optical amplifier. In one type of embodiment, a photodiode detects the output power of the semiconductor optical amplifier and a current detector detects the drive current of the semiconductor optical amplifier and the automatic power control loop uses both the detected output power of the semiconductor optical amplifier and the detected drive current.

Abstract: This invention relates to a method of securing magnetically encoded data from altering, forging, or counterfeiting. The invention pertains to magnetic storage media such as magnetic tape, magnetic striped cards, and other documents or objects which contain magnetic media. This invention utilized the inherent variations in the timing of magnetically encoded data in combination with the random effect of the magnetic media. Data is protected by reading the original encoded data just after encoding and storing this initial timing data stream. It is authenticated by a comparison of the timing data stream of any subsequent reading of this encoded data to the original timing data stream. Acceptance criterion depends on the magnetic media and applications chosen.
