Techniques are provided for estimating optimal atrioventricular pacing delay values for use in pacing the ventricles based on features of an intracardiac electrogram (IEGM) signal. Briefly, atrioventricular pacing delay pacing values are set based upon the location of atrial repolarization events within the IEGM.

Streak compensation with scan line dependent ROS actuation
Xerographic machines can print documents that have unintentional streaking parallel to the process direction. There are many possible source of the streaking. Currently, the streaking is minimized by using a cross process direction dependent modulation, called a profile, to modulate a modulated light beam being scanned across the photoreceptor.

Different profiles can be produced that work best for different area coverages. Choosing a profile from a group of profiles for use with each scan line can minimize parallel streaking for a wider range of area coverages.

By using lock signals (53) from phase-locked-loops (31) in stages (3) as control signals, an indication whether a channel is active or not can now be got much quicker due to lock signals being much faster available than automatic fine tuning signals. By using synchronization signals (54) from synchronization generators (4) as further control signals, a further indication is got. In a fast tuning mode, frequencies nearby active channels are detected, and in a fine tuning mode, channel frequencies are identified. According to the basic idea, lock signals originating from phase-locked-loops (31) in stages (3) can give first indications whether a channel is active or not, preferably and further advantageously in combination with second indications based upon synchronization signals (54).
Information processing apparatus
Relationship information is previously generated and stored by learning based on camera motion estimation information expressing motion of a video camera, which is detected by a desired image signal picked up by the video camera, and camera motion information expressing physical motion of the video camera, which was obtained by a sensor for detecting physical motion at the same time when the desired image signal was picked up by the video camera. Camera motion estimation information with respect to an inputted image signal is detected from the inputted image signal. Camera motion prediction information with respect to the inputted image signal is generated, based on the camera motion estimation information detected and the relationship information.

Gray code to sign and magnitude converter
The present invention relates to Gray Codes and their conversion to sign and magnitude representation. Gray codes are used in flash ADCs (analogue to digital converters), which convert an analogue waveform into a sampled binary value. This can be done via a thermometer code, and the present invention addresses the issue of the propagation of error due to an indeterminant thermometer code value. In particular the invention provides a Gray code to sign and magnitude converter arranged to produce for the bits of its output other than the sign bit the same code for the Gray codes that are the same distance from the boundary where the sign bit changes value when the Gray codes are arranged in order of their value.

Cooperative Vehicular Identification Systems and Methods, capable of monitoring and recording vehicular law violations, with the assistance and cooperation of the vehicles in violation, are disclosed. Real-time information from vehicular sensors is communicated to a Central Processing Unit (CPU). Strategically located Interrogator devices, on roads/highways, at intersections, in and around school zones, integrated with traffic lights, etc., issue inquiries/interrogations to passing-by vehicles. Vehicles proximate to such Interrogators respond with unique identifying information and with parameter lists provided by their vehicular sensors. Each Interrogator inquiry can provide data, including the lawful parameter limits (i.e. speed limit) associated with its location. In response to having successfully decoded an inquiry, and in response to the state of its vehicular sensors, a vehicular Transponder may transmit information to the specific Interrogator that has issued an inquiry. The Interrogator then relays relevant identifying information to the CPU for further processing.
