A Chinese text entry system with eye-tracking technique can be used for computer input of Chinese characters. The system is comprised of two main components: the Chinese pinyin software and the eye-tracking system. Chinese characters corresponding to pinyin input are selected from a list of candidate characters by selecting the proper character through eye-tracking identification and confirming the selection by pressing a readily accessible confirmation key. The Chinese pinyin software implements pinyin input at both the character and word level, choosing from multiple character or word homonyms as pinyin is entered. The system uses eye-tracking technology that is only used to identify the correct Chinese character, with the character selection and entry occurring when the confirmation key is pressed.

An implantable cardiac stimulation device, such as a pacemaker or Implantable Cardioverter Defibrillator, is configured to automatically monitor the effects of antiarrhythmic drugs on cardiac electrical signals within a patient to verify the efficacy of the drugs taken. In one example, an analysis of patient cardiac electrical signals is performed by comparing the cardiac electrical signals with values representative of the effects of different classes of antiarrhythmic drugs. If the implantable device determines that the prescribed antiarrhythmic drugs have not been effective, a warning signal is generated. The warning signal is conveyed directly to the patient via a bedside monitor and to the patient's physician via remote connection to an external programmer device so that both are notified of the drug efficacy problems. Additionally, the implantable device may be configured to automatically adjust pacing and defibrillation control parameters in an attempt to compensate for any lack of efficacy in the drugs. For example, the aggressiveness of overdrive pacing may be increased. Alternatively, a drug pump is controlled to adjust the dosage of antiarrhythmic drugs if an initial dosage is found to be ineffective.

A defensive aids suite for light armored vehicles utilizes four complementary sensor technologies including: visible and infrared optics, radar, acoustics and both laser and millimeter wave detection. Targeting and maneuvering optics are used for long-range threat detection with obscuration grenades and vehicle countermaneuvers being used to avoid a threat. Short range search and track radar is used with explosive or fragmentation grenades selected and launched to intercept and defeat the threat. Acoustic threat detection increases robustness and extends the detection range to include small calibers threats. Detection of active targeting systems by laser and radar warning receivers provides cueing information for targeting optics and fire control systems.

A dual technology printer includes first and second print stations having a polychromatic print engine and a monochromatic print engine, respectively. The print engines are preferably an ink jet print engine and a thermal print engine. A variable length media queue is formed between the two print stations.

Systems and methods for reducing head media spacing (HMS) from about 100 Angstroms to about 65 Angstroms or less, without substantial reductions in the carbon overcoat or lubricant thickness. A protruding feature extends above the actuated portion of the air bearing surface and generally covers the read-write sensors. The protruding feature can either be static or thermally actuated. The protruding feature is small enough to engage with the lubricant without causing large head media disturbances and lubricant pickup and re-distribution or preventing contact detection. The protruding feature is also extremely small relative to the size of the actuated portion of the air bearing surface, but large enough to provide a wear and corrosion resistance to head media spacing sensitive features.

There is provided a hierarchical shadow detection system for color aerial images. The system performs well with highly complex images as well as images having different brightness and illumination conditions. The system consists of two hierarchical levels of processing. The first level involves, pixel level classification, through modeling the image as a reliable lattice and then maximizing the lattice reliability using the EM algorithm. Next, region level verification, through further exploiting the domain knowledge is performed. Further analysis show that the MRF model based segmentation is a special case of the pixel level classification model. A quantitative comparison of the system and a state-of-the-art shadow detection algorithm clearly indicates that the new system is highly effective in detecting shadow regions in an image under different illumination and brightness conditions.
