  • Patent number: 8644028
    Abstract: One design aspect in electronic systems, such as communication systems, is noise suppression. More particularly, this relates to microphonics suppression in high-speed communication systems, such as microwave wireless radio systems. The present invention contemplates system design for substantially eliminating microphonic behavior created by mechanical stimulus such as vibrations and the drum effect. A preferred approach includes isolating the motherboard from its mounting harnesses (mechanical interconnection) and adding an echo damping and shock absorption pad to the underside of the enclosure cover to stiffen the enclosure cover while maintaining its light weight. Preferably also, this approach isolates the entire motherboard rather than a particular component. A design using this approach is particularly useful in an outdoor unit (ODU) of a split-mount microwave radio system.

  • Patent number: 8641012
    Abstract: A medical connector of improved configuration. Annular grooves are formed in both inner and outer surfaces of an outer peripheral portion of an elastic valve element to form an annular constricted section. An outer peripheral side from the constricted section is made to serve as an annular fixation section. A valve receiving seat is formed at an inner peripheral edge of an aperture portion in a housing, and an annular ring is fixed to the aperture portion to sandwich and support the annular fixation section between the valve receiving seat and the annular ring. Engaging projections formed on mutually facing surfaces of the valve receiving seat and the annular ring are engaged with the annular grooves, and either the engaging projection and/or the engaging projection is divided in a circumferential direction to have a plurality of projection-divisions.

  • Patent number: 8643707
    Abstract: An image signal processing apparatus performs gradation control on respective pixels. Specifically, the image signal processing apparatus includes an image signal processing unit which controls light emission and non-light emission of respective subfields so as to provide a field having a level of brightness. Here, the field is a unit display period of the pixels and divided into the subfields which have different light emission periods and are arranged in a predetermined sequence. In the predetermined sequence, the subfields are arranged in a manner such that a subfield having the shortest light emission period among the subfields is in the first place, one of a subfield having the longest light emission period and a subfield having the second longest light emission period among the subfields is in the second place, and the other one is in the third place.

  • Publication number: 20140028752
    Abstract: An image forming apparatus includes an apparatus body, a print medium, a conveyance unit, art image forming unit, a cutter unit, a holding unit, a sensor, and a controller. The print medium has an adhesive face with no separation sheet. The cutter unit cuts the medium having an image formed into a print medium piece. The holding unit is configured to hold the piece in a state in which the piece is drawable from outside of the body. The holding unit has a surface separatable from an adhesive face of the piece to hold the adhesive face of the piece. The sensor detects presence or absence of the piece held by the holding unit. After the sensor detects that the piece is drawn out, the controller controls the conveyance unit to convey the medium to the holding unit and controls the holding unit to hold the medium.

  • Publication number: 20140029469
    Abstract: A node transmits a route search demand, which is a demand to search for a route from the node to a predetermined device among adjacent communication devices, to an adjacent communication device that is not selected as a transmission destination of the route search demand. The node transmits the route search demand when the number of adjacent communication devices serving as confirmed routes is smaller than a predetermined number and when there is an adjacent communication device that has not been selected. The node stops transmission of the route search demand when the number of the adjacent communication devices serving as the confirmed routes reaches the predetermined number. The node transmits a warning to the predetermined device when the number of the adjacent communication devices serving as the confirmed routes is smaller than the predetermined number and when there is no adjacent communication device that has not been selected.

  • Publication number: 20140026706
    Abstract: A steering device easily sets an absorption amount of impact energy to a predetermined magnitude at a time when a female male shaft and a male shaft undergo relative contraction upon occurrence of a vehicle collision. If the male shaft undergoes contraction by a length against the female shaft, a serrated edge on a right-end surface of the female shaft is butted against a left-end surface of an impact-energy absorption part. Then, the serrated edge of a female serration is firmly butted against a left-end surface of the impact-energy absorption part to undergo plastic deformation, whereupon resistance to collapsing increases, thereby absorbing impact energy.
