Application controlled encryption of web browser data
A browser cache-securing component facilitates online communication of confidential data, such as for financial information, purchasing transactions, or user identification. Caching webpages for subsequent presentation enhances user productivity and efficiency while reducing burdens on network resources. Yet, the security risks of intrusions into cache memory are mitigated by retaining encrypted data in cache memory without prior decryption. A modest overhead in decrypting when and if the webpage is to be presented again gains a security and privacy advantage without taking away functionality. Decrypted versions of confidential data can thereby be relegated to volatile memory. Upon termination of a session, a session key shared by a network server is deleted, preventing subsequent decryption. Executing the browser cache-securing component in a virtual machine environment allows multiple browser types to benefit from the security feature.

Method and apparatus relating to power control
The present invention pertains to power control in cellular networks (1). A power control algorithm (201) is operated to control transmission powers on radio links (downlinks and/or uplinks). An information collector (203; 127) is adapted to collect power distribution information indicating how the transmission powers of a selected plurality of radio links are distributed in a dynamic power range extending from a minimum power level Pmin to a maximum power level Pmax.

Redundant media packet streams
This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. In particular, the invention concerns the transmitting and receiving of redundant media packet streams. Samples are extracted (556) from a first (904) and second (906) media packet stream.

Both media packet streams are simply processed all the way to the buffer without any particular knowledge that one of the packet streams is actually redundant. This simplifies the management of the redundant packet streams, such as eliminating the need for a “fail-over” switch and the concept of an “active stream”. The location is the storage space allocated to store one sample. The extracted sample written to the location may be written over another extracted sample from a different packet stream previously written to the location. These extracted samples written to the same location may be identical.
Hardware-enforced loop and NPIV hard zoning for fibre channel switch fabric
Hardware-enforced zoning is provided in Fiber Channel switches to protect against breaching of assigned zones in a switch network which can occur with software-based zoning techniques. The invention provides logic for performing a hardware-based validation of the Source ID S_ID of frames both at the point where the frame enters the Fiber Channel fabric, and at the point where the frame leaves the fabric. The S_ID is verified against an inclusion list or table of allowable S_IDs, which can be unique for each fabric port. The invention provides a way to increase the range of sources an inclusion table can express, by implementing wild cards, on an entry-by entry basis. If the S_ID is valid, it will enter the fabric and route normally. If invalid, the frame will not be routed but will be disposed of by the fabric according to FC rules. This prevents incorrect S_IDs from breaching the table-driven zoning at the point where frames exit the fabric, to prevent unauthorized access to devices connected to the switch network.

The write elements are arranged so that the write gaps of adjacent write elements are spaced from each other by not more than approximately one write gap width, while being generally aligned along an axis that is perpendicular to a direction of movement of the magnetic recording tape. The write elements may have a planar or vertical construction comprising plural thin film layers oriented in generally parallel or perpendicular relationship with the tape bearing surface. One or more read element arrays may also be provided.
Method of reading data stored in a data storage device and data storage device that performs a data read retry operation
A disk drive includes a disk having a track that includes a data sector divided by a servo sector so that a first data sector portion is on a first side of the servo sector, and a second data sector portion is on a second side of the servo sector. The disk drive reads data by: positioning the head at a first offset position with respect to the track and reading data from the data sector. When a read error occurs between the first and second data sector portions, the disk drive: stores the data from the first data sector portion in memory, moves the head to a second offset position with respect to the track, reads data from the second data sector portion with the head at the second offset position, and stores the data read from the second data sector portion in the memory.
Prism and optical device
A prism (10) is in the form of a polygonal prism and has a first optical surface (11), a second optical surface (12) and a third optical surface (13) formed on different surfaces of the prism. A light entrance region (11a) is provided at the center of the first optical surface (11), a light exit region (12a) is provided at the center of the second optical surface (12) and a substantially flat light reflecting region (13a) is provided at the center of the third optical surface (13). Suppose that there is a virtual surface between the light reflecting region (13a) and the first optical surface (11), the virtual surface is positioned more inward in the prism than a peripheral region of the third optical surface (13) extending from the light reflecting region (13a) to an edge (14) between the third optical surface (13) and the first optical surface (11).
Adjustable lens mounting assembly
A lens barrel is mated with a lens mount through use of a screw thread whereby relative rotation adjusts lens focus. The lens barrel and lens mount are additionally provided with an interengaging formation that is interposed between an optical axis of the lens barrel and the screw thread. This formation provides a cylindrical sliding contact which isolates any particles produced by operation of the screw thread from reaching the optical components at or near the optical axis.
Objective optical system for endoscopes
An objective optical system includes, in order from the object side, a first unit having two lenses with negative refracting power and positive refracting power, a stop, and a second unit with positive refracting power to satisfy the following condition: 3.0
Incident-light controlling apparatus
An incident-light controlling apparatus has a first aperture in a substrate, a diaphragm blade which rotates around an axis, and controls light passing through the first aperture, by the diaphragm blade rotating alternately between a first stationary position coinciding with the first aperture, and a second stationary position retracted from the first aperture, a permanent magnet joined directly to the diaphragm blade, at a position of the axis of rotation of the diaphragm blade, and magnetized in a direction of a plane of rotation of the diaphragm blade, and a pair of coils having a winding around cores disposed such that an end portion of each coil faces the magnet. The diaphragm blade rotated alternately between the first and second stationary positions due to an interaction between a generated magnetic field upon passing an electric power, and a magnetic field generated due to the magnet.
Disclosed is a camera module with a hinge spring which can stably support a lens barrel which is driven in a vertical direction for automatic focusing and which is made of lightweight resin, the camera module including a cylindrical lens barrel with lenses disposed therein for collecting images of external objects, a housing encasing the lens barrel in a manner such that the lens barrel vertically moves in an optical axis direction of the lenses, an automatic focusing actuator installed in the housing to cause linear motion of the lens barrel in the optical axis direction, and a ring-shaped hinge spring extrusion-molded using resin having elasticity to support an upper portion of the lens barrel and guide the linear motion of the lens barrel.
