Abstract: A third party or third party device 110, 116 makes an access request to a wireless communication device 100. The wireless communication device 100 generates a token specifying an identity for use by the device when making a connection request. The wireless communication device 100 also specifies alright wherein the right is for access to a capability of the wireless communication device 100. When a connection request is received the token for identity verification is checked and access is allowed according to the rights specified if the identity is verified. Access via the user interface 208 is also granted in the same fashion. A wireless communication device 100 arranged for implementing this method is also described.

Abstract: A system (10) includes a first communication device (40), a second communication device (45), and a content management server (15). The first communication device (40) includes a first content memory (365) for storing a first plurality of active content (360) including at least one active content (370) stored using a content version (375). The first communication device (40) further includes a first resource memory (385) for storing a first plurality of resources (380). The second communication device (45) includes a second resource memory (415) for storing a second plurality of resources (410). The content management server (15) is adapted to send a second content version (412) of the active content (370) to the second communication device (45) in response to receiving a content sharing request (390). The second content version (412) is compatible with the second plurality of resources (410).

Abstract: An x-ray fluorographic system produces frame images at a low dose rate for both on-line and off-line use. Background noise is filtered by first producing a mask which defines the boundaries of the structural features of interest. The mask is used to select the background pixels for filtering, while enabling the structural pixels to pass unfiltered to the display.

Abstract: An x-ray imaging system includes a source of x-rays, a video camera which produces an image signal formed by x-ray attenuation values, and image signal processor and a video monitor for displaying the x-ray image. The system also has an automatic image control that includes a peak detector, an average brightness detector and a transfer function generator for the image processor. The peak detector receives the image signal and produces a video gain control signal for controlling the video camera in response to a comparison of a peak level of the image signal to a peak reference level. The average the brightness detector employs the image signal to produce a feedback signal which controls by the source of x-rays. The transfer function generator produces a histogram of intensity levels in the image signal which histogram forms a look-up table that is used by the image processor to transform the image signal into the adjusted image signal for display.

Abstract: An x-ray fluorographic system which produces a cineangiogram enables a feature in the image to be identified with a cursor and automatically tracked in subsequent images. The identified feature, such as a suspected lesion in a coronary artery, is located in each x-ray frame of the cineangiogram and the data is displayed such that the feature remains motionless in the center of each successive image.
