  • Publication number: 20090217216
    Abstract: A methodology is provided for optimizing circuit parameters of circuits including carbon nanotube transistors. The method comprises mapping (122) selected transistor design parameters (118), based on carbon nanotube process parameters (120) and selected circuit topologies (114), into carbon nanotube physical attributes. A circuit layout is generated (124) from the carbon nanotube physical attributes and simulated (128). The steps are repeated until circuit specifications (130) are met. The carbon nanotube physical attributes may include, for example, the catalyst width (74) for growing a plurality of carbon nanotubes (72) or number of segments in a serpentine electrode structure (88, 89, 90) contacting a single carbon nanotube (81).

  • Publication number: 20090109885
    Abstract: Energy consumption in a network is reduced by a first node transmitting a message at a first power level and determining if the message is received by a neighboring node of the network. The message is retransmitted at a higher power level if the message is not received by a neighboring node. A second node, in a neighborhood of the first node, selects one of two or more receiver sensitivity levels and senses the received signal strength of the message. The second node activates an energy-consuming functional element to decode the first message only if the received signal is above the selected receiver sensitivity level. The receiver sensitivity levels are selected in accordance with a selection process, such as a random process, that may be adapted.

  • Patent number: 7302098
    Abstract: An electronic device (1100) and a method for character segmentation (100) includes an image analyzer (1110) that generates individual character images. The image analyzer binarizes (115) a gray scale image (200) of a horizontal row of characters by using a general threshold method to generate a first image (300). The image analyzer also binarizes (120) the gray scale image using an edge detection method to generate a second image (405). The image analyzer determines (125) a character row region (425) of the second image by using horizontal projection analysis. The image analyzer isolates (130) the character row region of the first image using the character row region of the second image. The image analyzer uses the character row region to generate (135) individual character images. The electronic device may include an image capture device (1105) and a character recognition program (1115).

  • Patent number: 7176970
    Abstract: A photodetector (105) generates an electrical signal that has a value that changes approximately linearly at a rate that is proportional to an amount of light intensity incident on a photodetector since a most recent reset command was received at a reset input of the photodetector. A measurement circuit (110) generates a comparison state that is based on a comparison of the value of the photodetector signal to a reference signal in response to one of a plurality a sample pulses. A control circuit (160) generates the plurality of sample pulses at non-uniform time intervals and generates an elapsed time as an accumulation of the non-uniform time intervals occurring from the reset command to a change of the comparison state. In one embodiment, the reciprocal of an accumulated duration of the non-uniform time intervals is a linear function of a number of time intervals after the reset command.

  • Patent number: 7095892
    Abstract: A method and apparatus for object-of-interest image capture accomplishes the functions of capturing (120) a current image, determining (125) an object region of the object-of-interest in the current image, calculating (130) a contrast measurement of the object region, and identifying (135) the current image as having an optimized object region when an iteration measure meets a criterion. The current image is captured using a local exposure value determined from luminance readings of pixels within an object region of an object-of-interest of a previous image.

  • Patent number: 5394476
    Abstract: A volume control circuit comprises a variable gain stage (306), having a variable gain, and an up/down counter (324) for counting. The counter (324) has a counter input (321) and a counter output (333) for providing a first word (333) for controlling the gain of the gain stage. A microprocessor interface (326) includes an interface output (323) for providing a second word. A digital magnitude comparator (333) compares the first (323) and second (333) words. The comparator having a first input (333) connected to the counter output, a second input connected to the interface output (323), and a comparator output connected to the counter input (321), provides a count signal (329) if the words do not match and for providing a non-count signal (329) if the words match. Thus, responsive to the count signal (329), the up/down counter (324), counts from the first word, in a direction approaching the second word by a least significant bit to form a new first word, for controlling the gain of the gain stage.
