Systems and methods for automatically correcting apparent distortions in close range photographs that are captured using an imaging system capable of capturing images and depth maps are disclosed. In many embodiments, faces are automatically detected and segmented from images using a depth-assisted alpha matting. The detected faces can then be re-rendered from a more distant viewpoint and composited with the background to create a new image in which apparent perspective distortion is reduced.

The present invention is directed to a minimally invasive system and method for monitoring changes in a cervix opening during labor, including changes in its diameter. The system having a probe and a monitoring unit serve to monitor periodically the cervix opening during labor and obtain measurements of the diameter of the cervix opening. The probe primarily includes a camera for imaging the cervix opening, a lens to provide an optimal field of view for the camera at close range to the cervix opening, a light source to illuminate the cervix and a balloon to expand the vagina around the probe and position the probe to allow unobstructed imaging of the cervix. The monitoring unit which controls the probe to acquire images of the cervix and receives and processes image data from the probe includes a processor which uses image segmentation techniques to identify and measure the opening of the cervix and generates data signals. The monitoring unit also includes an image display which displays information based on the data signals for viewing by health care providers and/or the patient, including graphic images of the cervix opening and other text information relating to the cervix opening as an indicator of the progress of labor. In one embodiment, the processor implements segmentation techniques and/or blob analysis algorithms to analyze the images of the cervix to identify the opening and measure its diameter. Other algorithms may also be implemented to correct for any spatial distortion, particularly barrel distortion.

An arrangement for providing protection to wireless portable transponders (including resonant tags such as RFID tags) from unauthorized interrogation by employing a mechanical means for disabling reception by or from the antenna of the transponder. The tags can be protected from receiving or providing unauthorized or unwanted information. Contemplated are mechanical means that permit the owner to decide when reception/interrogation of personal or other information is not desired by employing the provided mechanical disable control means. Also broadly contemplated herein is the altering interrogation characteristics of RFID tags to such an extent that they may still be read at a close range instead of the original range, and this result of this altering is visible to the user.

The invention discloses a resonant tracking non-contact power supply device and a resonant tracking non-contact power supply method and aims to mainly solve the problems that the transmission efficiency and transmission distance are reduced and induction voltage is sensitive to load change caused by the change of a resonant point in an LC resonant non-contact power supply. An excitation source with adjustable frequency and amplitude is formed through an adjustable switch power source (102) and a half-bridge switch (103) and is applied to a resonant circuit consisting of an emitting coil (112) and a resonant capacitor (113); a current signal in the resonant circuit is acquired by using a current sampler (104); an automatic resonant frequency tracking circuit consists of a comparator (105), a phase discriminator (106) and a controllable oscillator (107); when the resonant point changes, an excitation frequency is automatically adjusted and an automatic excitation voltage adjusting circuit consists of a wave detecting and filtering circuit (109), an error amplifier (110) and the adjustable switch power source (102) to automatically adjust the excitation voltage when a load changes, so a load voltage is basically constant. The resonant tracking non-contact power supply device can overcome the effects caused by resonant frequency change and load change and is applicable for the occasion of close-range and high-efficiency non-contact power transmission.

An unmanned range-programmable airburst weapon system provides automated tracking and prosecution of soft targets such as UAVs at close ranges. A range-programmable gun that fires airburst rounds and a seeker that images the target within a FOV are mounted on a gimbaled turret. A tracking controller is responsive to a target cue to point the seeker to acquire the target and to subsequent tracking commands from the seeker to maintain the target in the seeker's FOV. A fire controller is responsive to tracking commands and range-to-target measurements to compute a ballistic firing solution to range program an airburst round and to point and fire the gun so that the round explodes in mid-air at a predicted target position.
