摘要： A head driving unit the generates a driving waveform, each driving waveform including a plurality of driving pulses, and selects one or more driving pulses to be applied to a liquid drop discharging head in response to data corresponding to an image. By selecting a plurality of selection signals that defines the driving pulses to be applied to the liquid discharging head, the head driving unit can change a recording density or record multiple value images.

摘要： A navigation method and apparatus and a navigation program are provided for guiding a vehicle to a destination along a guide route. An off-route detection unit detects an off-route condition when the vehicle is displaced from the guide route and a guide route searching unit searches or determines, when the off-route detection unit detects an off-route condition, a route from a present position of the vehicle to the destination or return point on the guide route. The guide route determining or searching unit includes a weight factor determining unit for determining a weighting value to modify or scale a road parameter used in determining the guide route, a modifying unit for modifying the parameter based on the weighting value, and a calculating unit for calculating a route from the present position of the vehicle to the destination or the return point on the guide route, as a function of the modified parameter. A display is provided for displaying the guide route to the operator of the vehicle.

摘要： A vehicle navigation system for indication of the current vehicle position provides improved guidance to the driver when he is exiting from a freeway onto a freeway connector road segment (a freeway bifurcation), with the destination being a street (non-freeway road segment) linked to the freeway connector. In this case there is a possibility that the displayed sign text data at the first decision point upon exiting from the freeway does not correspond closely enough to the actual freeway signs, which tend to emphasize the connecting freeways rather than the street. This would tend to confuse the driver. Therefore, before the vehicle passes through the first decision point upon exiting the freeway, the sign text data for the freeway connector segment of the segment prior to the last freeway connector segment connecting to the destination street is displayed at the first guidance point, and not just the destination street. After the vehicle passes the first decision point on the freeway connector, if the sign text data for the last freeway connector segment on that set of freeway connectors is included in the sign text data for the freeway connector segment of one segment before the last road segment, the last sign text data is displayed; if not, the sign text data for the freeway connector segment of one segment before the last is displayed. Hence, the system reliably displays data indicating the freeway bifurcation onto which the driver wants to turn.
摘要翻译：用于指示当前车辆位置的车辆导航系统当驾驶员从高速公路离开高速公路连接道路段（高速公路分叉）时提供改进的指导，目的地是一条街道（非高速公路路段）连接到高速公路连接器。在这种情况下，存在从高速公路退出时在第一决定点显示的签名文本数据与实际的高速公路标志不足够的可能性，这样往往强调连接高速公路而不是街道。这往往会混淆司机。因此，在离开高速公路的车辆通过第一判定点之前，在第一引导点显示在连接到目的地街道的最后一个高速公路连接器段之前的段的高速公路连接器段的符号文本数据，而不是只是目的地街道。在车辆通过高速公路连接器上的第一个决定点之后，如果该组高速公路连接器上的最后一个高速公路连接器段的符号文本数据被包含在最后路段之前的一个段的高速公路连接器段的符号文本数据中，显示最后的签名文本数据; 如果没有，则显示最后一段之间的一段的高速连接器段的符号文本数据。因此，系统可靠地显示指示驾驶员想要转向的高速公路分叉的数据。
