In an example, a printhead includes an electronically programmable read-only memory (EPROM) having a bank of cells arranged in rows and columns, each of the cells having a addressing port, a row select port, and a column select port. A conductor is coupled to the addressing portion of each of the cells. A shift register circuit is coupled to at least one of the row select port and the column select port of each of the cells, the shift register circuit storing samples of an input signal responsive to a plurality of clock signals. A decoder is coupled to the shift register circuit to provide the input signal based on a logical combination of a plurality of data signals and at least a portion of the clock signals.

Abstract: In an example implementation, a touch-sensitive illuminating display includes a transparent flexible touch layer, a transparent top conductive layer adjacent the flexible touch layer, a bottom conductive layer, and an electroluminescent layer and variable-thickness dielectric layer sandwiched between the top and bottom conductive layers. Pressure against the flexible touch layer is to reduce the dielectric layer thickness and bring the top and bottom conductive layers closer together, causing the electroluminescent layer to emit light where the pressure is applied.

Abstract: One example of a device includes an antenna, a memristor code comparator, and a controller. The antenna is to receive a wake up signal. The memristor code comparator is to compare the wake up signal to a reference signal. The controller is to provide a trigger signal to wake up the device in response to the wake up signal matching the reference signal.

Abstract: Apparatus, systems, articles of manufacture, and methods to facilitate capacitive code comparing are disclosed. An example apparatus includes a comparator to receive a first portion of a first input and a second portion of a second input, the comparator including a capacitor. The example apparatus further includes a peripheral determination circuit to cause the capacitor to couple the first portion to the second portion; in response to coupling the first portion to the second portion, ground the capacitor; sense a current discharged by the grounded capacitor; and determine a Hamming distance of the first input and the second input based on the sensed current discharged by the capacitor.
