Abstract: A method may include etching a number of holes into a carrier wafer layer to form a plurality of filters in the carrier wafer layer, pattering a chamber layer over a first side of the carrier wafer layer to form chambers above each filter formed in the carrier wafer layer, forming a layer over the chamber layer, grinding a second side of the carrier wafer layer to expose the number of holes etched into the carrier wafer layer, and bonding a molded substrate to the carrier wafer layer opposite the chamber layer.

Abstract: In one example in accordance with the present disclosure a liquid level sensing device is described. The device includes a carrier and a liquid level sensing device disposed on the carrier. The liquid level sensing interface has an aspect ratio of at least 1:50. A number of liquid level sensing components are disposed on the liquid level sensing interface. The number of liquid level sensing components detect a liquid level in a liquid container. The liquid level sensing device also includes an electrical interconnect to output data collected from the number of liquid level sensing components.

Abstract: A seismic system includes a wireless sensor node. The wireless sensor node includes a global positioning system (GPS) device to receive a GPS time value at an interval; a temperature sensor to measure temperature; an oscillator to measure time; and a memory to store the GPS time value, the temperature, and the oscillator time. The wireless sensor node also includes a processor to determine a rate of temperature change during the interval, and to dynamically update the interval to receive the GPS time value from the GPS device, based on the rate of temperature change.

Abstract: Methods of three-dimensional printing can include iteratively applying a polymer build material as individual layers to a powder bed, where the polymer build material includes from about 80 wt % to 100 wt % polymer build particles, and based on a three-dimensional object model, selectively applying a binder agent including an aqueous liquid vehicle and polymer binder particles onto the individual layers of the polymer build material. The polymer binder particles have or are capable of having a melting temperature lower than a melting temperature of the polymer build particles. The methods can include exposing the powder bed to heat at a temperature less than a melting point of the polymer build particles but greater than a melting temperature of the polymer binder particles. The heat causes the polymer binder particles to melt to adhere the polymer build particles together to form a three-dimensional object.

Abstract: In an example, a method for making a fluid ejection apparatus may include forming a molding material over a fluid passage on a back surface of printhead die, embedding the printhead die in an encapsulant in a cavity in a printed circuit board such that at least one drop ejector of the printhead die is exposed at a front side of the printed circuit board, removing the encapsulant at a back side of the printed circuit board to expose the molding material, and removing the molding material to form a fluid feed slot through which fluid may flow to the fluid passage opening in the printhead die.

Abstract: A printhead may include a number of s-shaped dies embedded in a moldable substrate. An medium-wide array may include a number of printheads with each printhead including a number of s-shaped dies and an ejection fluid feed slot to provide a single type of ejection fluid to the s-shaped dies. An s-shaped die of a printhead may include a number of columns of nozzles and an electrical interconnect coupled to a number of firing chambers associated with each of the nozzles, the electrical interconnect positioned adjacent to the number of columns.
