222results about How to "Reliable capture" patented technology

A subarray of a CMOS imaging sensor array is addressed to detect when a target symbol is fully within a field of view of an imaging reader to improve reader performance at high swipe speeds.

A solid-state imager is mounted at a point-of-transaction workstation for capturing images of one- and two-dimensional indicia and is operated at high speed to resist image blurring due to relative movement between the target and the imager. Dedicated hardware assistance and computation resources are allocated to decode multiple, continuous and simultaneous video streams from multiple imagers at the workstation.

An implantable cardiac stimulation device and associated method set an atrial capture detection window by verifying that inter-atrial conduction is intact, and then measuring the inter-atrial conduction time. The measured inter-atrial conduction time may then be used for setting the atrial capture detection window. Capture verification of a stimulated atrial site is then implemented by detecting a conducted depolarization at another atrial site or in the opposite atrial chamber. A signal received during an atrial capture detection window is compared to a depolarization signal threshold or to a depolarization signal template in order to verify detection of a conducted depolarization signal as evidence of capture at the stimulated site. By sensing depolarization signal away from the stimulated site, the negative effects of lead polarization normally encountered when detecting an evoked response are avoided.

An ink tank of the foam type which is provided with a detected portion capable of exactly and surely detecting the amount of ink used by the printer or remaining in the ink tank. The ink tank includes a sub ink chamber that is diposed or formed between a main ink chamber and an ink outlet of an ink tank of a foam type. When an amount of air flowing into the sub ink chamber increases, one or more reflecting surfaces of a right-angled prism, which function as ink interfaces, resume their original function of reflecting surfaces, thereby enabling the detection of an ink end. Air bubbles having entered the sub ink chamber are surely led onto the one or more reflecting surfaces by a bubble storage part. At an ink passage having a narrow width, which is defined by the one or more reflecting surfaces, air bubbles are pressed against the one or more reflecting surfaces to be put to a crushed state and in surface contact with the latter. Air bubbles are surely led onto the one or more reflecting surfaces, and are crushed and pressed against the reflecting surfaces. This configuration prevents the one or more reflecting surfaces from being covered with ink retained in spaces among the air bubbles. Therefore, the ink end can be detected surely and exactly.
