  • Patent number: 8441525
    Abstract: A method for synchronizing a function on a remote device with a function on a primary device includes selectively broadcasting, from a radio frequency (RF) transmitter of the primary device, data broadcast on channels at different times relative to a fixed period strobe signal of the primary device. Only the channels that have a noise level below a specified threshold level selectively broadcast the data and each of the channels have an associated fixed time frame offset relative to the fixed period strobe signal. Each of the channels is broadcast after their associated fixed time frame offset expires. An RF receiver of the remote device receives the data on one of the channels. The data on each of the channels is received at different times, depending on its associated fixed time frame offset, which results in the data on each received channel having an associated received time reference relative to a strobe signal of the remote device.

  • Patent number: 7978259
    Abstract: An image capturing apparatus illuminates an object and captures an image of the object using the reflected light from the object. On a circuit substrate mounted an image sensor, a plurality of light-emitting devices are mounted in the peripheral positions of the image sensor. By means of a ring-shaped light guide member, the light from the plurality of light-emitting devices is guided to an image capturing range, so as to illuminate the object. With this, by mounting a light receiving system and a light emitting system on an identical substrate, miniaturization can be achieved, and the image capturing range can be illuminated by substantially uniform light. Also, using the ring-shaped light guide member, an optical unit is housed inside the ring, thus enabling further miniaturization.

  • Patent number: 7879246
    Abstract: It is an object of the present invention to provide an effective technique for achieving a higher level of water quality control in a water treatment apparatus. Representative water treatment apparatus according to the present invention may include a purifying section, a sterilizing section, a water storing section and a water quality detection sensor. The water quality detection sensor is immersed in the water storing section. The water quality detection sensor not only serves as a means for detecting the quality of water in the water storing section, but also as a means for detecting deposition of biomembrane on the detecting section of the water quality detection sensor due to deterioration of the sterilizing performance of the water storing section. As a result, an efficient water quality control system can be realized.

  • Patent number: 7777808
    Abstract: An image capturing apparatus illuminates an object and captures an image of the object using the reflected light from the object. The image capturing apparatus includes an image sensor for capturing an image of the object by receiving reflected light, distance-measuring light-emitting devices for irradiating the object with spot light, and a control circuit for driving the distance-measuring light-emitting devices, detecting the spot light positions of the distance-measuring light-emitting devices from an image captured by the image sensor, and obtaining the distance to the object. The image sensor provided for capturing an image of the object can be used as a photodetector device for distance measurement. With this, it becomes unnecessary to separately provide a photodetector device for distance measurement, which enables miniaturization of the image capturing apparatus, as well as cost reduction.

  • Patent number: 7756503
    Abstract: Heretofore, a plurality of packages were used in a high frequency module in which a plurality of waveguide terminals were positioned resulting in problems, such as degradation of characteristics in the connection lines between packages, lower ease of assembly when mounting and connecting the connection lines, increased cost, and so forth. To solve these problems, a plurality of cavities having a part or the entire side metallized is formed in a multi-layer dielectric substrate. The multi-layer dielectric substrate is provided with a plurality of waveguide terminals, microstrip line-waveguide converters, RF lines, bias and control signal wiring, and bias and control signal pads. A high frequency circuit is mounted within the cavity and sealed with a seal and cover. This is intended to reduce the number of package, improve performance, improve fabrication, and lower the cost.

  • Patent number: 7690827
    Abstract: A light guide member illuminates with uniform light intensity distribution using the point light source light. On the lower end of the light guide member having a pair of side faces disposed oppositely, a groove is provided for receiving light output from each point light source and diffusing the above received light to at least three directions from the incident side toward the output side. Light components having directions using side-face reflection are generated in the light guide member, enabling light output to multiple directions from the cylindrical-shaped light guide member, and uniform illumination over a wide range. By using the ring-shaped light guide member, cost reduction is effectively achieved, and miniaturization of the illumination mechanism and the image capturing mechanism can also be attained.

  • Publication number: 20070232281
    Abstract: A wireless communication device, an individual information writing device, and an individual information setting method that efficiently write individual information, such as a unique identifier used for wireless communication, to each wireless device. An address writing device transmits a unique address setting communication request. A wireless device has a control unit that checks whether a provisional address is set in a unique address memory. When a provisional address is set, the control unit measures the signal intensity of a received unique address setting communication request with an electric field intensity measuring unit. When the electric field intensity is greater than a threshold value stored in an address setting condition memory and thereby satisfies an address setting condition, the wireless device performs a process for setting a unique address and then transmits a completion notification to the address writing device.
