Abstract: A printhead includes an aperture plate having an array of nozzles therethrough. The printhead further includes an array of jets fluidly connected to an ink supply chamber, each jet comprising a body chamber having a length:width ratio of at least 3:1. The body chamber comprises a first end, and a second end opposite the first end, the first end and the second end defining a height. Ink flows into body chamber through an inlet, and an outlet on the first end is fluidly connected to a nozzle. A diaphragm is present adjacent the second end of each body chamber in the array of jets. The body chambers are angled relative to a row of nozzles.

Abstract: What is disclosed is a method for monitoring a subject for cardiac arrhythmia such as atrial fibrillation using an apparatus that can be comfortably worn by the subject around an area of exposed skin where a photoplethysmographic (PPG) signal can be registered. In one embodiment, the apparatus is a reflective or transmissive wrist-worn device with emitter/detector pairs fixed to an inner side of a band with at least one illuminator emitting source light at a specified wavelength band. The illuminator is paired to a respective photodetector comprising one or more sensors that are sensitive to a wavelength band of its paired illuminator. The photodetector measures intensity of sensed light emitted by a respective illuminator. The signal obtained by the sensors comprises a continuous PPG signal. The continuous PPG signal analyzed for peak-to-peak pulse points from which the existence of cardiac arrhythmia such as atrial fibrillation event can be determined.
