A vehicle fuel emissions system includes a fuel tank, a tank pressure sensor indicating a pressure differential between the tank and a port communicating with the atmosphere, a pump for selectively producing vacuum in the tank, and a passage connecting the pump and a pressure sensor air reference port external to the system.

In a method for checking the plausibility of objects in driver assistance systems for motor vehicles is described, two measured variables are derived from position data from two object position-finding systems of the vehicle that operate independently of one another, for an object located by the two position-finding systems, one variable for each position-finding system, these variables representing one and the same physical parameter, and the two measured variables are then checked for consistency, which is characterized by the fact that the parameter is the time to collision of the vehicle with the object, which is calculated in advance.

An encryption error monitoring system for checking packets transmitted between a private network and an external network. The system includes includes a detector module (60) which is connected to receive the packet for determining whether or not the packet is successfully encrypted in accordance with a specific security protocol such as IPSec (Internet Protocol Security). The detector module reads from the packet a sender's address and a destination address, and provides an error signal when the packet is judged not to be successfully encrypted. A manager module (80) is connected to the detector module within the private network to create, upon receipt of the error signal, a report including the sender's address and the destination address with regard to the packet judged not to be successfully encrypted. The detector module is configured to have a judge means (66) which reads a header of the packet and checks whether or not the header includes a protocol code that matches with a particular code identifying the specific security protocol. When the header does not include the protocol code in match with the particular code, the judge means provides the error signal to notify the encryption error. Thus, the encryption error can be determined only by referring to the unencrypted header and therefore without necessitating the decryption of the packet.

An eye refractive power measurement apparatus by which an examiner can properly check reliability of a measurement result while time and effort of the examiner are saved. The eye refractive power measurement apparatus for measuring eye refractive power of an examinee's eye has a measurement optical system for projecting a measurement target onto a fundus of the eye to pick up a fundus reflection image by a two-dimensional image-pickup element, a storing device which stores the picked-up fundus reflection image as a measurement image, a display device, a measurement condition judging device which makes a judgment as to whether or not the stored measurement image satisfies a predetermined measurement condition, and a first display control device which controls the display device to display the stored measurement image when the measurement condition judging device judges that the measurement condition is not satisfied.

An onboard display device in accordance with the present invention includes a display section (11) attached to an instrument panel of a vehicle. The section (11) has a second display area (11b) and a first display area (11a). The second display area (11b) shows at least the speed as vehicle condition images indicating the conditions of the vehicle. The first display area (11a) shows a navigation image and other secondary images. The display section (11) measures greater in width than in height with an aspect ratio of 7:3 or greater. The aspect ratio is the width / height ratio of a display area. The onboard display device allows for a visibility-improved simultaneous display of the secondary image, such as a navigation image, and the vehicle condition image, such as a speed display, which presents information on the conditions of the vehicle.

A method as well as a respective checking apparatus for checking a document of value (1), with which the document of value (1) at least in a partial area is illuminated with an intensity (IB) and at different measuring places (2) the intensity (IT) of the light transmitted through the partial area of the document of value (1) and the intensity (IR) of the light reflected by the partial area of the document of value (1) is captured. For eliminating the impact of thickness fluctuations within the document of value and an at the same time simple checking it is provided that the intensities (IT, IR) of the transmitted and reflected light are captured separately, that for each of the different measuring places (2) the sum (IT+IR) of the intensities (IT, IR) of the transmitted and reflected light is calculated, and that the sum (IT+IR) is compared to a predetermined standard value (IS).

In order to check endoscope channels, a predetermined quantity of liquid is led, at a predetermined pressure, through the channel that is to be checked, and the period of time for this is measured and evaluated. The predetermined quantity of liquid is determined via the volume of a liquid container whose outlet is capable of being connected to the channel that is to be checked. A compressed air source subjects the liquid in the container to a predetermined pressure. A sensor registers whether the liquid level in the container has dropped below a predefined value. A control unit measures the period of time within which the predetermined volume of liquid has flowed through the channel that is to be checked.
