  • Publication number: 20170341581
    Abstract: A bird's eye view image is displayed to be recognized by an operator intuitively and precisely, irrespective of the displayed direction of the bird's eye view image. The display device has a plurality of cameras having optical axis directed obliquely downward to take images around a self-propelled industrial machine. A view point converting section converts the camera images to an upper view point to create bird's eye images, and an image composing section creates a composite bird's eye view image by composing respective bird's eye images around a symbol image of a dump truck. A direction superposing section superposes a forward direction indicator to indicate the forward direction of the dump truck on the composite bird's eye view image, and a monitor mounted in a cab of the dump truck displays the composite bird's eye image in an arbitral direction which is composited with the forward direction indicator.

  • Publication number: 20060223589
    Abstract: A communication apparatus which communicates with an external apparatus by receiving a communication request transmitted from the external apparatus based a call-out number uniquely allocated to the communication apparatus, includes: a communication request receiver which receives identification information allocated to the external apparatus and the communication request independently of a call-out number of the external apparatus; a display which displays information; an information storage which stores an association table associating the identification information of the external apparatus with apparatus information used for displaying in reception of the communication request from the external apparatus; and a display controller which, when the communication request receiver receives a communication request with identification information, displays apparatus information recorded in the association table stored in the information storage on the display, which is associated with identification information

  • Patent number: 5727522
    Abstract: In a control system for an ignition timing of an internal combustion engine and a control method for the ignition timing, a basic ignition timing of the engine is set, an engine speed is detected, a target value of the engine speed is set while the engine is in idling condition, an ignition timing correction amount is determined depending upon a difference of the target value and a detected engine speed while the engine is in idling condition, the basic ignition timing is corrected with the correction amount, and after the engine speed becomes higher than or equal to a predetermined value, the engine is controlled with the corrected ignition timing.

  • Patent number: 5685285
    Abstract: The invention provides an internal combustion engine controller for an internal combustion engine having a fuel tank which can be purged of fuel vapor via a purge line connected through a canister unit, to a suction input of the internal combustion engine. The amount of fuel vapor stored in the canister or the amount of fuel vapor supplied to the internal combustion engine according to the operating state and operation range of the engine are calculated, and the purge control valve and air-fuel ratio control characteristics are adjusted using the calculated value. At the same time, appropriate control of the amount of fuel vapor and purge control valve when diagnosing the purge pipe system failure by application of pressure to the purge pipe system, are provided. Both internal combustion engine control with the minimum change in air-fuel ratio and purge control are ensured, and highly reliable diagnosis of the purge pipe system is realized.
