Abstract: A controller for a print head of an inkjet printing device is described that is configured to generate a virtual timing signal during a printing pause of the printing device, and to use the virtual timing signal for the generation of pre-ejection pulses in order to produce a reliable regeneration of the nozzles of the print head during the printing pause.

Abstract: Provided is a device for controlling the printing of a print image with a nozzle of an inkjet printing device. The device is configured to—given the presence of a relatively long printing pause of the nozzle insert one or more print image-independent pre-ejection pulse phases, followed by a print image-dependent pre-ejection pulse phase, between the printing of two successive dots, in order to efficiently and reliably increase the print quality of the printing device.

Abstract: In the print data for a nozzle of a printer, white dots are replaced by pre-ejection pulses. One or more repetitions of the pre-ejection pulses may be inserted into the print data, depending on the actual print speed of the printer, to determine print speed-dependent print data with which the nozzle is activated to print a print image with high print quality.

Abstract: A teeth cleaning device for simultaneously cleaning multiple teeth, of a user includes a mouth insert for inserting into the mouth of the user, a plurality of cleaning structures attached to the mouth insert or integrally formed together with the mouth insert, a coupling element attached to the mouth insert; and a drive device. The drive device includes a vibration motor, which can be connected to the coupling element such that the vibration motor vibrates the mouth insert during the operation of the teeth cleaning device, and a cleaning program selection element for selecting a cleaning program that defines a vibration frequency of the vibration motor within a specified frequency range and/or a vibration amplitude of the vibration motor within a specified amplitude range. The disclosure further relates to a method for producing such a teeth cleaning device.

Abstract: A controller adapted for an inkjet printing system is described. The controller can include an analyzer and a prefire inserter. The analyzer can be configured to determine whether a nozzle arrangement should generate a fire pulse in a current line, and whether the last preceding fire pulse was further in the past than an interval value threshold N. The prefire inserter can be configured to insert one or more prefire pulses into the N lines before the current line.

Abstract: In a method and a device to sort pixel data in a print data stream, a data sorting memory is used configured so that it can be written per column and read per row. The pixel data are entered per column into the data sorting memory in the order of the incoming print data stream. Via the per-row readout the pixel data are re-sorted into an order suitable to control the print head. The sorting can thereby take place in only one write process and one read process.

Abstract: In a method and device for transfer of data over a data connection from a transmitter to a receiver by means of packets, repetition packets with respect to predetermined packets are transmitted given free transfer capacity The packets and their corresponding repetition packets comprise an identifier by use of which the receiver can identify the packets. Given a faulty transfer of a packet, the receiver can identify this quickly via the provision of the repetition packets and can introduce corresponding countermeasures This method is in particular provided for serial high-capacity data connections in which a faulty transfer of individual packets cannot be precluded in principle.

Abstract: A polycarbonate powder having a relatively lower water content may be produced by preheating a solution of polycarbonate in a nonaqueous solvent (e.g., methylene chloride) prior to subjecting said solution to steam precipitation.

Abstract: An apparatus for sampling and draining media from a vessel or reactor is described. The apparatus comprises: (a) a valve body with a generally longitudinal axis extending therethrough; (b) a moveable disc assembly positioned within a central channel of the valve body; (c) a valve operating rod extending within the valve body along its longitudinal axis; (d) a piston actuator assembly for positioning the disc assembly along the central channel; and (e) a sampling port extending away from the valve body. The valve body comprises the central channel, which has an upper end communicable with a port in the wall of the vessel or reactor and a side outlet which extends away from the longitudinal axis of the valve body. The valve operating rod has an upper end which is communicable with the disc assembly. The piston actuator assembly is communicable with an opposite, lower end of the valve operating rod.

Abstract: The present invention relates to an arrangement in a time division multiplex link having at least two pairs of multiplexors and demultiplexors interconnected by separate transmission lines, i.e., redundant transmission systems, with delay, in which time division multiplex channels are formed through the cyclic scanning of the multiplexor inlets and demultiplexor outlets, respectively so that data signals presented to the multiplexor inlets are transferred via the time division multiplex channels in the form of sampling signals to regeneration arrangements connected to the demultiplexor outlets. The sampling signals passed over the separated (redundant) time division multiplex channels are interlaced, i.e., different delays on different transmission lines, thereby producing a resultant sampling density which, when a fault occurs, is reduced by a factor corresponding to the share of the faulty channel in the total number of channels.
