Abstract:
A portable electronic key easily findable even if dropped into water. The portable electronic key includes an upper cover and a lower cover, a hermetically sealed space is formed, in which electrical equipment such as a board, a battery, and an antenna are arranged. The upper cover and the lower cover are formed of foam resin, and a grain pattern is given to surfaces thereof. A specific gravity of the entire electronic key is set at 1 or less, thus enabling the portable electronic key to float on the surface of the water.
Abstract:
A method is provided for releasing a secret number of a theft prevention function in jet propulsion boat, which is equipped with the theft prevention function. The theft preventing function is capable of turning a power source ON by an occupant inputting the secret number. In the method, at least one of a plurality of harness connected to the theft prevention function is removed to input, a predetermined number (number for release), whereby the secret number is rendered capable of being released. Since the secret number is rendered capable of being released by removing at least one of a plurality of harnesses connected to the theft prevention function, and by inputting a predetermined number, it is possible to make forgetting the secret number and maintenance of the theft prevention function compatible.
Abstract:
A jet propulsion watercraft is provided with a multifunctional display portion that displays operating information and various types of warning conditions. Operation switches operate a content displayed in the multifunctional display portion. A fuel injection system injects fuel for a driving source. A warning mark warns of a faulty condition developing in the fuel injection system. Functions are provided that cause the warning mark to light steadily or flash off and on and that indicate a faulty symptom by means of a flashing pattern of a warning lamp (for example, the warning lamp flashes off and on once, twice, three time, or the like) given when the operation switches are operated while the warning mark is lit steadily or flashing off and on. A prompt action can be taken against a malfunction of the fuel injection system. As a result, convenience in eliminating malfunctions of the fuel injection system can be enhanced.
Abstract:
To provide a vehicle navigation system that can accurately display a position of a vehicle that has the navigation system mounted thereon and a target direction even when the vehicle is stopped or traveling at low speed. The vehicle navigation system includes a device that senses a traveling state of a vehicle, a device that judges whether or not the vehicle is stopped or traveling at a low speed, and a device that smoothes GPS positioning data so that error components contained in the GPS positioning data are canceled out or compensated for when the vehicle is stopped or traveling at a low speed. The navigation system further includes a device that calculates the current position based on the smoothed GPS positioning data. The smoothing device outputs new positioning data, for example, based on current GPS positioning data and previous GPS positioning data.
Abstract:
This invention relates to facilitating the layout of cables in an electric connector box for a vehicle. Within the fuse box are disposed a large number of plug-in type blade fuses and screw type fuses. A difference in height is provided between mounting surfaces of the block fuses between terminal boards. The terminal boards of one type of fuse is set at a higher position than the terminal boards of the other type of fuse. Therefore, cables can be drawn out in the same direction without mutual interference. Although cable, which is laid inside, is screwed to the back of a substrate, the height of a screw portion for the cable is also set so as to avoid interference of the cable with back connections of the blade fuses.
