Abstract: A multi-directional single pass printing apparatus may include a print head comprising a collection of slots. The collection of slots may include a central slot for delivering a central slot fluid type, a first serial arrangement of first slots on a first side of the central slot to deliver a first series of respective fluid types and a second serial arrangement of second slots on a second side of the central slot opposite the first side. The second series of slots are to deliver a second series of respective fluid types, wherein the second series of respective fluid types mirror the first series of respective fluid types with respect to the central slot fluid type.

Abstract: According to an example, multi-directional single pass printing may include utilizing a print head that includes slots that include a first slot for a first ink color, and two or more additional slots. A slot of the additional slots may be disposed on a first side of the first slot, and another slot of the additional slots may be disposed on a second side of the first slot. The additional slots may include a further ink color. Data may be forwarded to a set of slots when a direction bit related to the print head is set to a first value, and to another set of slots when the direction bit is set to a second value. A number of channels for forwarding the data to the slots may be less than the number of slots.

Abstract: A transistor device is provided, including a lightly doped layer of semiconductor material of a first type and a body region of semiconductor material of a second type. A source region of the first type is formed in the body region. The source region being more doped than the lightly doped layer. A drain region of the first type is formed in the lightly doped layer, the drain region being more doped than the lightly doped layer. A drift region of the lightly doped layer is further provided disposed between the body region and the drain region. Additionally, a gate electrode is provided surrounding the drain region. The gate electrode is partially disposed over a thin oxide and partially over a thick oxide, wherein the gate electrode extended over the thick oxide from the thin oxide controls the electric field in the drift region to increase the avalanche breakdown of the drain region.

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: An apparatus and method for controlling temperature fluctuations between printhead dies in a multiple printhead die printer. By reducing temperature variations, changes in image intensity that are attributable to temperature variations are reduced.

Abstract: The cell type (i.e. alkaline, Ni-Cd, etc.) of a battery is determined by reference to characteristics of its electrical behavior during charging. Exemplary characteristics include the magnitude of the initial voltage rise and the rate of initial voltage rise. Depending on the outcome of this determination, the charging conditions can be changed (e.g. the charging current can be interrupted if the cell is determined to be a non-rechargeable type). The invention finds particular utility in connection with electronic products such as calculators and portable computers.
