| 20110221587 | TIRE WEAR DETECTION DEVICE - A tire wear detection device includes a wear detector embedded in a tread of a tire, a sensor unit arranged on a wheel, and a receiver unit arranged on a vehicle body. The wear detector includes a piezoelectric element and a resonance circuit, which generates a radio wave signal from a voltage signal generated by the piezoelectric element. The sensor unit transmits through wireless communication a pressure data signal indicating an internal air pressure of the tire, generates a wear data signal indicating a wear state of the tire based on the received radio wave signal, and transmits through wireless communication the wear data signal. The receiver unit receives the pressure data signal and the wear data signal from the sensor unit. | 09-15-2011 |
| 20110153120 | TIRE CONDITION MONITORING APPARATUS WITH KEYLESS ENTRY FUNCTION - A tire condition monitoring apparatus including a keyless entry portable communication device capable of transmitting and receiving RF signals, sensor units, each of which is attached to a wheel and transmits, as an RF signal, a tire condition data signal, out-of-cabin antennas each corresponding to the wheel, and a control unit mounted on a vehicle body. The control unit executes a keyless entry function based on transmission and reception of RF signals with the portable communication device via the out-of-cabin antennas, and sends a command signal, which is an RF signal, to the sensor units through the out-of-cabin antennas. Upon receiving the command signal, the sensor unit executes an operation that corresponds to the command content of the command signal. | 06-23-2011 |
| 20110012378 | METALLIC RESIN COVER AND METHOD OF PRODUCING THE SAME, AND DOOR HANDLE FOR VEHICLE - A metallic resin cover constitutes a portion of an outer wall of a human detection device in which a detection electrode of a capacitance sensor is provided, and which detects whether a human touches or approaches the human detection device. The metallic resin cover includes a covered body; and a metal layer that has a metal-object discretely arranged structure in which a plurality of metal objects are discretely arranged. The metal layer covers an outer surface of the covered body. | 01-20-2011 |

| 20090302644 | Hood impact absorbing apparatus - The present invention provides a hood impact absorbing apparatus capable of further mitigating an impact that a collision body receives from a hood than ever, wherein a push-up rod pushes up the rear end of a hood at the time of a collision of a vehicle, and when a collision body is battered against the top surface of the hood in this state, the rear end of the hood descends and the distal end of the push-up rod slidingly contacts and moves a rear-side flat portion and an arm intermediate curved portion in the rear end of the hood, and herein, a slide contact angle (θ) in the arm intermediate curved portion is larger than a slide contact angle (θ) in the rear end of the rear-side flat portion, thereby, during a process in which the rear end of the hood descends, peaks at which an absorbing amount of impact energy becomes large can be provided at least twice, and as a result, the impact can be mitigated further than ever. | 12-10-2009 |
| 20090079652 | Portable remote controller for tire status detector - A portable remote controller for a tire status detector, includes a portable casing, a transmission circuit disposed in the casing, a low-pass filter disposed at an output side of the transmission circuit for permitting a signal with a frequency of not more than the first frequency to pass through the low-pass filter, a receiving circuit disposed in the casing, a high-pass filter disposed at an input side of the receiving circuit for permitting a signal with a frequency of not less than the second frequency to pass through the high-pass filter, a ferrite bar antenna housed in the casing and having a ferrite bar wound with an antenna coil, the antenna coil having two terminals, one of which being connected to the ground and the other being connected in common to the low-pass and high-pass filers and a duplexer composed of the low-pass and high-pass filters. The ferrite bar antenna is used both for transmission of the long wave signals and for receipt of the ultra high frequency signals. | 03-26-2009 |
| 20080308206 | WHEEL UNIT - A wheel unit includes a wheel and a pressure adjusting device installed on the wheel to adjust the pressure in the tire. The pressure adjusting device includes a cylinder and a piston provided in the cylinder. The piston moves in the cylinder by centrifugal force generated by rotation of the wheel so that air introduced into the cylinder from the outside is injected to an internal space of the tire. The wheel includes a mounting hole, which extends in the radial direction of the wheel and opens to the internal space of the tire. The pressure adjusting device is installed in the mounting hole such that the moving direction of the piston agrees with the radial direction of the wheel and that the pressure adjusting device is not exposed to the outside from an outer surface of the wheel except in the internal space of the tire. | 12-18-2008 |
| 20080303672 | VALVE-INTEGRATED TRANSPONDER - A valve-integrated transponder includes an air valve and a casing that are integrated with each other, and is disposed within a tire. The air valve is press-fitted to a valve hole in a wheel rim. The casing houses a substrate having a detecting element mounted thereon, an inverse F antenna element, a supporting member, and the like, and is provided with a partition-like reinforcement rib. The reinforcement rib extends along an extension of an axis of the air valve and is loosely fitted in a recessed slot of the supporting member. The antenna element supported by the supporting member has a substantially line symmetrical shape where a pair of radiation conductors symmetrically extend away from each other. | 12-11-2008 |
| 20080303652 | VALVE-INTEGRATED TRANSPONDER - A valve-integrated transponder includes an air valve and a casing that are integrated with each other, and is disposed within a tire. The casing houses a substrate having a detecting element mounted thereon, an inverse F antenna element, and a supporting member. The antenna element has a substantially line symmetrical shape where a pair of radiation conductors extend away from each other. A longitudinal direction of the substrate is substantially perpendicular to an axial direction of the air valve, and a lateral direction of the substrate is inclined relative to a well of a wheel rim. The two radiation conductors of the antenna element disposed on the substrate are inclined at a predetermined angle with respect to the substrate, so as to be disposed substantially in parallel to the well that extends at the inner side of the transponder as viewed in the radial direction of the tire. | 12-11-2008 |
| 20080231077 | Wireless-equipped vehicle - A wireless-equipped vehicle includes a vehicle body made of a metal and including a ceiling, a main body and a pillar connecting the ceiling and the main body, the pillar having a side face, an interior wireless device located in the vehicle body to receive radio waves from outside the vehicle body, and a magnetic loss material disposed on the side face of the pillar to limit AC current conduction between the ceiling and the main body. | 09-25-2008 |
