20100233975AUTOMATED POWER CONTROL TO OPTIMIZE POWER CONSUMPTION AND IMPROVED WIRELESS CONNECTION - A method for automatically adjusting signal output power of a ZigBee wireless module. The method includes sending a signal with an output power from a transmitter of a ZigBee module to a receiver. The ZigBee module includes a power amplifier/low noise amplifier (PA/LNA) circuit. The output power can be adjusted between a minimum level and a maximum level. Additionally, the method includes generating a Link Quality Indicator (LQI) by the receiver based on the signal strength and returning the LQI to the ZigBee module. If the LQI is not within a predetermined range between a maximum value and a minimum value, the method includes adjusting the output power for sending next signal. If the output power from the transmitter has reached to the minimum level or the maximum level, the method further includes adjusting the PA/LNA circuit of the ZigBee module for maintaining the LQI within the predetermined range.09-16-2010

20090194324ELECTRIC DISTRIBUTION BOX - An electric distribution box includes a resin exterior cover which houses an interior component and has an opening for resin-molding the exterior cover on a bottom wall of the exterior cover, and a resin cap which is fit into the opening to close the opening. A flange formed on an outer periphery of the resin cap is kept in intimate contact with the bottom wall of the exterior cover. A molding hole for forming a locking piece by resin molding is provided on the flange. The locking piece locks the resin cap to the opening of the exterior cover. A swell is formed at an entire peripheral edge of the molding hole of the resin cap. An outer face of the interior component is kept in intimate contact with the swell so that the molding hole of the resin cap is closed by the outer face of the interior component and the flange is kept in intimate contact with the bottom wall of the exterior cover.08-06-2009
20090200298BOX WITH COMPONENT INTERNALLY HOUSED - A box includes a first cover, a second cover, and an interior component housed in an internal space formed when the first cover and second cover are fit to each other. The first cover and the second cover have engaging mechanisms which engage the one end of the first cover to the one end of the second cover, and have retaining mechanisms which retain the other end of the first cover to the other end of the second cover. The first cover and the second cover are fit to each other in a normal state in a case that the engaging mechanisms are engaged with each other in a state where the retaining mechanisms are normally retained to each other. A projection is provided on at least one of the one end of the first cover and the one end of the second cover. When an engagement between the engaging mechanisms is in an abnormal state, the projection abuts against at least the other of the one end of the first cover and the one end of the second cover so that a gap between the one end of the first cover and the one end of the second cover is assured and the interior component housed in the internal space can be seen through the gap.08-13-2009
20090242267BOX FOR ACCOMMODATING ELECTRIC CONNECTION BOX - A box for accommodating an electric connection box is provided. The box includes a lower cover which comprises a plurality of walls for surrounding a space to accommodate the electric connection box toward a predetermined insertion direction, and an upper cover. The plurality of walls includes: a first wall which extends along the insertion direction; second and third walls which extend from the first wall in a direction intersecting the insertion direction and faces each other; a fourth wall which extends from the first, second and third walls at a deep side of the insertion direction so as to support the electric connection box; and a fifth wall which extends from the second and third walls along the insertion direction, and is substantially parallel to the first wall so as to press-sandwich the electric connection box by the first and fifth walls.10-01-2009

20080209961LOCK MECHANISM - In a sidewall of a connector frame, a cantilevered lock arm is provided. A lower end of the lock arm is connected to the sidewall with a curved supporting unit interposed therebetween. The lock arm extends upward from the supporting unit with a space. The supporting unit has a slit to increase the flexibility of the lock arm. An engagement protrusion is provided on the lock arm. Moreover, a fitting sidewall is provided in a box body, and a lock wall having a lock protrusion is provided outside the fitting sidewall. The lock protrusion includes a downward-facing engagement surface. A mold hole used in molding the engagement surface is formed between the fitting sidewall and lock wall. An abutment surface is provided at an upper end of the fitting sidewall and contacted with the supporting unit to close communication between the mold hole and the slit.09-04-2008
20080239692MOUNTING STRUCTURE OF ELECTRICAL JUNCTION BOX - In a mounting structure of an electrical junction box, the electrical junction box is vertically mounted on a wall surface along a vertical direction in a state where mating faces of an under case member and an upper case member are set in the vertical direction. Each of the under case member and the upper case member has a pair of left and right locking projections provided therein. A bracket including a backside plate part and a pair of case hook parts provided upright from both sides of the backside plate part is disposed along the vertical direction on the wall surface. The electrical junction box is slidingly inserted from above along the backside plate part in the vertical direction until both pairs of locking projections of the under case member and the upper case member are locked to the pair of case hook parts. Thus, the electrical junction box is mounted on the wall surface by use of the bracket.10-02-2008
20080256996Lock Mechanism of Electric Connection Box - A lock mechanism includes: a lock arm provided in a cantilever manner on an inner wall of a part compartment of a box body of an electric connection box; and a lock projection provided to the lock arm on its surface facing a part housed in the part compartment. The lock arm can be divided in a longitudinal direction into: a base end region fixed to the inner wall; upper end region located in the free end which interferes with the part and receives a pressing force for unlocking operation; and a middle region located within a predetermined distance range between the base and upper end region. The flexural rigidity of the base and upper end region is set larger than that of the middle region by providing ribs on the base and upper end region and providing no ribs on the middle region.10-23-2008
20080257600Wire Harness Leading-Out Port Structure of Electric Connection Box - A wire harness leading-out opening is provided at a junction between an electric connection box and a bottom surface cover which constitute an electric connection box. A cylindrical wire harness leading-out guide is provided on the periphery of the wire harness leading-out opening, and is formed in a way that the both circumferential ends of a half-cylindrical body formed on the electric connection box and a half-cylindrical body formed on the bottom surface cover are coupled to each other. In the inner circumference of a circumferential junction between the peripheral walls of the two half-cylindrical bodies, a concave portion is provided to accommodate a loose portion of an armoring member wrapped around the outer circumference of the wire harness.10-23-2008
20090115296Electrical Junction Box - An electrical junction box comprises a box body provided with a first groove; an attachment bracket provided with a second groove; and a lower cover provided attached to the bottom surface of the box body. When the attachment bracket is properly mounted on the box body, the first and second grooves are arranged to form a single continuous third groove. A protrusion is provided on the lower cover and fits to the third groove.05-07-2009
