Abstract: In some examples, a fluid ejection die includes a plurality of nozzles arranged in a plurality of nozzle columns, the plurality of nozzle columns distributed across a width of the fluid ejection die in a staggered manner, wherein nozzles of each respective nozzle column of the plurality of nozzle columns are spaced apart along a length of the fluid ejection die, wherein the plurality of nozzle columns includes a first pair of neighboring nozzle columns that are spaced by a first distance across the width. The plurality of nozzle columns includes a second pair of neighboring nozzle columns that are spaced by a second distance across the width, the second distance being larger than the first distance.

Abstract: A firing circuit for a thermal inkjet-printing nozzle includes a heater resistor and a switch. The heater resistor heats ink to cause the ink to be ejected from the nozzle. The heater resistor has a first end and a second end, the second end connected to a ground. The switch controls activation of the heater resistor. The switch has a first end connected to a voltage source and a second end connected to the first end of the heater resistor. The switch operates in a constant current mode, such that an at least substantially constant current flows through the heater resistor upon activation.

Abstract: A system for sound generation and noise feedback is disclosed for attachment to a bicycle training wheel. The system includes a plurality of sound generators attachable by a means for fastening to a rotatable surface of the training wheel. As the sound generators rotate with the wheel, sound is generated in proportion to the speed of wheel rotation. The sound generation system further includes a sound generator attachable to the support frame of a bicycle wheel. A clapper is pivotably attachable proximal to the sound generator, for intermittent contact with the sound generator when the clapper is engaged by one or more projections connected to, and rotated by the wheel. The generation and feedback system further includes a light generator and an electrical circuit connected to the sound generator for intermittent generation of sound and light in proportion to the rotation of the training wheel.

Abstract: Disclosed is a control system and methodology used for defining and executing parametric test sequences using automated test equipment. The control system is divided into components which separate fixed, reusable information from information which is specific to particular tests. One component contains reference data which describes the configuration of the wafer being tested as well as specifications for the tests to be carried out. Another component contains a set of measurement algorithms that describe individual tests to be performed on generic types of devices or parametric test structures. Execution of a test is carried out by a general test program which retrieves stored reference and test definition information and supplies it to the measurement algorithms to enable them to perform measurements on specific devices in the user specified sequence.
