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 optical touch screen arrangement includes two optical cameras arranged so that their planar fields of view intersect each other in a touch area situated adjacent a display screen operative for displaying visual prompts to solicit action from a user. The user's finger, or a pen, entering the touch area is detected, as is the user's signature.

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.

A snare-type device for removing an elongated structure such as, for example, a pacemaker lead. The device first includes a sheath having a first lumen formed therein, the first lumen having a distal end and being dimensioned to receive the elongated structure therein, and being adapted to allow advancement of the sheath along the elongated structure. The sheath also has second and third parallel lumens formed therein, all of the first, second and third lumens being unitarily formed in the sheath. The device also includes a snare contained in the second and third lumens in the sheath. The snare has a snare loop extending out of the second and third lumens, at and generally extending around the distal end of the first lumen.

A capsule endoscope is provided with an image pickup section having a CCD image sensor, a plurality of LEDs for emitting illumination light, a control circuit for controlling the image pickup section and the LEDs, a transmitting/receiving circuit for transmitting an image signal as a radio signal, and a battery for supplying electric power to each part of the capsule endoscope inside of a capsule case. When the capsule endoscope reaches a large intestine which is a lower digestive tract, the transmitting/receiving circuit receives an image capture initiation signal from an external transmitter provided outside of the body. The control circuit then activates the LEDs and the image pickup section to perform the image capturing at a predetermined interval.

A target is illuminated with illumination light for image capture by a solid-state imager of an imaging reader. Internal reflections of the illumination light at a window are minimized, if not eliminated, by configuring the window as a non-planar optical element operative for redirecting the internal reflections away from the imager to enhance reader performance.

A defect detected by a wafer inspection tool is reliably captured by a defect review tool. A defect review condition in the defect review tool is varied depending on defect attributes provided by the wafer inspection tool so as to optimize the review process. For example, review magnification is varied depending on the size of the defect, or the frame addition number is varied depending on the maximum gray level difference.

In a system analysis apparatus, a per-SrcIP filter section captures packets in client-Web server segments on a per-SrcIP basis. An ON/OFF filter section allows captured packets to pass through only when its flag is set to “ON”. A request/response analysis section controls a flag of the ON/OFF filter section of the next segment so that the packets of the next segment are captured only when the present segment is in a response waiting statue. A range control section controls a SrcIP range of packets to be captured by the per-SrcIP filter section.
