TL;DR: In this article, a 3D point cloud model memory unit 709 stores a point cloud showing three-dimensional coordinates obtained by laser measurement which is carried out simultaneously to the image-capturing of the images as a road surface shape model.
Abstract: It is an object to measure a position of a feature around a road. An image memory unit stores images in which neighborhood of the road is captured. Further, a three-dimensional point cloud model memory unit 709 stores a point cloud showing three-dimensional coordinates obtained by laser measurement which is carried out simultaneously to the image-capturing of the images as a road surface shape model. A model projecting unit 172 projects a point cloud on the image, and an image displaying unit 341 displays the point cloud superimposed with the image on the displaying device. Using an image point inputting unit 342, a pixel on a feature of a measurement target is specified by a user as a measurement image point. A neighborhood extracting unit 171 extracts a point which is located adjacent to the measurement image point and superimposed on the feature for the measurement target from the point cloud. A feature position calculating unit 174 outputs three-dimensional coordinates shown by the extracted point as three-dimensional coordinates of the feature for the measurement target.

TL;DR: In this article, a one-way/one-time hash function is applied to the current password to form a current tag and a next password is selected for a next packet that includes next data.
Abstract: A method authenticates packets that are transmitted serially in a network. A current password is selected for a current packet to be transmitted. The current packet includes current data. A one-way/one-time hash function is applied to the current password to form a current tag. A next password is selected for a next packet that includes next data, and the one-way/one-time hash function is applied to the next password to form a next tag. The one-way/one-time hash function is then applied to the next data, the next tag, and the current password to obtain a hashed value. The current packet is then transmitted to include the hash value, the current data, the current tag, and a previous password of a previous transmitted packet to authenticate the current data.

TL;DR: In this paper, a power amplifier unit having a Power Amplifier which can be used efficiently without causing any trouble in operation is considered. But, the power amplifier is in a first period performing low power output operation or in a second period performing high power output output operation.
Abstract: A power amplifier unit having a power amplifier which can be used efficiently without causing any trouble in operation. A control section (11) makes a decision based on an estimated output power level whether the power amplifier is in a first period performing low power output operation or in a second period performing high power output operation. During the first period, a DC/DC converter (2) is brought into active state and a power supply voltage Vdd2 is supplied as the operating power supply voltage of an HPA (1). During the second period, activation/inactivation of the DC/DC converter (2) and on/off of a switch (3) are controlled based on a power supply voltage level VM detected by an operating power supply voltage detecting circuit (13) and one of the power supply voltage Vdd2 or a power supply voltage Vdd3 is supplied as the operating power supply voltage.

TL;DR: The results of the above study should provide system designers with guidelines, as well as insight, into the design of an architecture based on NT for supporting applications with components having real time constraints.
Abstract: Windows NT was not designed as a real time operating system, but market forces and the acceptance of NT in industrial applications have generated a need for achieving real time functionality with NT As its use for real time applications proliferates, based on an experimental evaluation of NT, we quantitatively characterize the obstacles placed by NT As a result of these observations, we provide a set of recommendations for users to consider while building real time applications on NT These are validated by the use of NT for a prototype application involving real time control that includes multimedia information processing The results of the above study should provide system designers with guidelines, as well as insight, into the design of an architecture based on NT for supporting applications with components having real time constraints

TL;DR: The technologies most commonly used in commercial HVICs, including junction-isolation, thin silicon-on-insulator (SOI), and thick SOI approaches are described.
Abstract: High-voltage ICs (HVICs) are used in many applications, including ac/dc conversion, off-line LED lighting, and gate drivers for power modules. This paper describes the technologies most commonly used in commercial HVICs, including junction-isolation, thin silicon-on-insulator (SOI), and thick SOI approaches. Emerging technologies such as thin silicon membrane are also discussed.
