  • Patent number: 7719213
    Abstract: An actuating mechanism for a door includes a first antenna block having a first integrated microcontroller electrically connected to a first transceiver device and a first antenna. A second antenna block having a second integrated microcontroller is electrically connected to a second transceiver device and a second antenna. A processor device is electrically connected between the first and second microcontrollers and a first switch. The first and second antennas receive a first radio frequency signal from a third, mobile transceiver device. The processor device measures a time difference of arrival (TDOA) of the first radio frequency signal. The processor device computes a direction of arrival (DOA). The DOA measurement is compared against a predefined range of DOAs. The processor device sends a control signal to the first switch to actuate the door in the event of a match.

    Abstract: Devices and methods are provided for the controlled release or exposure of reservoir contents. The device includes a reservoir cap formed of an electrically conductive material, which prevents the reservoir contents from passing out from the device and prevents exposure of the reservoir contents to molecules outside of the device; an electrical input lead connected to said reservoir cap; and an electrical output lead connected to said reservoir cap, such that upon application of an electrical current through the reservoir cap, via the input lead and output lead, the reservoir cap ruptures to release or expose the reservoir contents. The reservoir contents can comprise a release system containing drug molecules for release or can comprise a secondary device, such as a sensor. In one embodiment, the controlled release system is incorporated into an implantable drug delivery device.

  • Publication number: 20050234397
    Abstract: This invention describes novel methods and devices for stabilizing and retracting tissue during surgery, in particular internal tissue. Patches of material, preferably biodegradable, are adhered to tissue surfaces. By manipulation of the patches, for example directly with forceps, or via sutures attached to the patches, tissues can be retracted or otherwise manipulated with minimal trauma to the tissues. The method is especially useful in minimally-invasive surgery.

  • Patent number: 6879326
    Abstract: There is disclosed an apparatus and method for highlighting one or more selected portions of a display screen. The apparatus comprises a color shift controller capable of receiving a user input selecting one of a plurality of portions of a display screen and, in response to the user input selection, modifying the value of the pixels within the selected portion to increase the color temperature of the pixels. The method comprises selecting a portion of the display screen and increasing the color temperature of at least one color within the selected portion of the display screen. In one advantageous embodiment of the present invention, the color shift controller modifies white color pixel values in a selected portion of the display screen to new white color pixel values that have a higher color temperature. The higher color temperatures increase the apparent brightness of the displayed images.

  • Patent number: 6832000
    Abstract: Pixels in a video image may be segmented based upon selected criteria, such as a common color, texture, shape, amplitude range or temporal variation. Color values for these pixels may be used to calculate a color probability function which indicates the probability that the color value of the pixel will lie within a designated range of values. The pixels are also used to calculate a texture probability function that indicates whether the pixel represents a designated texture. Pixels that are assigned to a given segment may then be further processed to improve the quality of an image. In this manner, pixels that identify grass, sky, human skin, etc. may be identified and processed in order to achieve a more pleasing appearance.
