A producing method of a flexible wired circuit board that can prevent the formation of a gap between an elongate substrate and a stiffener sheet bonded thereto to prevent contamination of the flexible wired circuit board obtained. In the process subsequent to the process of forming a conductive pattern 3 on a surface of the elongate substrate 1 by the semi-additive process using electrolysis plating and then annealing the elongate substrate 1 with the conductive pattern 3 in its wound up state, a stiffener sheet 9 having a width narrower than the elongate substrate 1 is bonded to the back side of the elongate substrate 1. Thereafter, an oxidized film formed on a surface of the conductive pattern 3 is removed and then a solder resist 11 is formed thereon. This prevents the strip of the stiffener sheet 9 from the elongate substrate 1 and in turn prevents etching solution or developing solution from entraining in a gap therebetween.

The apparatus comprises a mold having a forming surface with a contour corresponding to said three-dimensional pattern, and having edges corresponding to boundaries of the dish, which edges are defined by side walls essentially perpendicular to the forming plane; a forming device comprising a fluid basin and pairs of electric discharge members within the fluid and having an opening facing the mold to allow transmission of a pressure wave from the fluid to the metal plate; and an electric discharge circuitry for discharging a short and intense electric current through the pairs of electric discharge members generating an electric spark or breakdown within the fluid to yield formation of plasma, vapor or both.

A server apparatus encrypts content, based on a distribution key, and transmits the encrypted content to a PC via a network. The PC, to which a memory card is connected, outputs the received encrypted content to the memory card. The memory card decrypts the encrypted content using the distribution key, converts the data format of the decrypted content, encrypts the content using a medium unique key that is unique to the memory card, and records the resulting re-encrypted content internally. A playback apparatus decrypts the re-encrypted content using the medium unique key, and plays back the decrypted content.

Disclosed are techniques for securing electronic control units (ECUs) in a vehicle. A security platform for a vehicle includes a key distribution center (KDC) for the vehicle. The KDC is configured to verify that a digital certificate associated with a first electronic control unit (ECU) on the vehicle is a valid certificate, where the digital certificate indicates a first security level of the first ECU. The KDC is configured to generate, based on the first security level of the first ECU, one or more security keys for secure communication between the first ECU and a set of ECUs on the vehicle, and provision the one or more security keys to the first ECU and the set of ECUs. In some embodiments, the KDC uses the provisioned keys to authenticate each ECU when the vehicle is powered up.

A method for regulating execution of an application program includes a process for preparing the application and a process for executing the application. The preparation process divides the application program into related segments and encrypts instructions of at least one segment. The preparation process positions encrypted instructions in at least two discontiguous regions within an executable file and associates header information with at least one discontiguous region. The header identifies a decryption key and the location of the other discontiguous region. The resulting execution file thus has portions that would not execute and would cause an operating system to call a responsive process. The execution process initiates execution of the protected application when at least a portion of the application instructions are available to the computer only in encrypted form. The user is authenticated, after which the encrypted portions can be decrypted and execution resumed. The processes may also include capability to detect and respond to tampering, or the ability to block execution snooping via a debugger. Also provided are systems and methods to allow debugging of code extensions to protected applications without sacrificing protection of the application. A Secure Debugger allows extension developers to examine memory and set breakpoints in their own extensions, without permitting them to view information in the rest of the protected application.

A curved foil-shaped electro-optical product (1) is provided having at least a first region with a basis substrate layer (10) of a shrunken organic substance, having a convex side and a concave side and comprising at the convex side (12) of the basis substrate layer at least a further layer (20), the electro-optical product further comprising at least a second region with an electro-optical structure (20).

A method for a medical system to transmitting patient information to an external USB storage device includes checking the validity of the USB storage device according to the registered information therein, generating a new identification file according to a new times of using value that is incremented each time the validity checks are passed, and a unique ID number of the USB device, and writing the new identification file into the USB storage device to replace the old identification file.

A card processing device (100) that handles a magnetic card and an IC card wherein, when a card (50) is taken into a main body (20) and if the card is a magnetic card, the inserted card (50) is taken in by intermittently transporting the card to a predetermined position and, after that, by continuously transporting the card and, if the card is an IC card, the inserted card (50) is taken in by continuously transporting the card. When the card (50) is ejected out of the main body (20) and if the card is a magnetic card, the card is ejected by continuously transporting the card to a predetermined position and, after that, by intermittently transporting the card and, if the card is an IC card, the card is ejected by continuously transporting the card.

When, in a state where a developer borne by a developer bearing member is sandwiched by an opposing portion of an image bearing member and the developer bearing member, C denotes capacitance between the image bearing member and the developer bearing member, ΔV denotes a development contrast, Q/S denotes a charge amount per unit area of the developer borne by the developer bearing member, and Δv denotes a peripheral velocity ratio which is a ratio of a peripheral velocity of the developer bearing member to a peripheral velocity of the image bearing member, a first peripheral velocity ratio is set so that |Q/S×Δv|≦|C×ΔV| is satisfied, and a second peripheral velocity ratio which is larger than the first peripheral velocity ratio is set so that |Q/S×Δv|>|C×ΔV| is satisfied.

An attacker is prevented from obtaining information about the configuration of a computer system. Each of one or more revealing content elements that may be found in outgoing data transmitted by the computer system and that are capable of being used by the attacker to obtain the information about the configuration of the computer system is associated with one or more respective replacement content elements. Outgoing data to be transmitted by the computer system are then scanned for these one or more revealing content elements. A revealing content element found in the outgoing data is replaced by a replacement content element from the one or more replacement content elements associated with that revealing content element. This is done before the outgoing data is transmitted.
