A security cable can include a restraining cable and a lock unit attached to the restraining cable. The lock unit can be configured to removably fasten to a computing device. The lock unit can be further configured to switch the security cable between a first configuration and a second configuration. In the first configuration, the lock unit can be fastened to the computing device and can place the computing device in an inactive state. In the second configuration, the lock unit can be removable from the computing device and may not place the computing device in the inactive state.

A privacy filter includes a plurality of micro louvers. Each micro louver of the plurality of micro louvers is a same size. Each micro louver of the plurality of micro louvers are laid flat on top of each other to form the privacy filter. The plurality of micro louvers includes a first micro louver and a set of micro louvers. The first micro louver is in a fixed position. The set of micro louvers has a first piezo element at a first end of each micro louver and a second piezo element at a second end of each micro louver. The first end is opposite the second end.

A method for balancing load across multiple file servers is disclosed. In one embodiment, such a method includes monitoring load experienced by multiple file servers arranged in an active-active configuration. The method receives, from a client node, a request for an address associated with one of the file servers. The method determines a particular file server of the file servers that, if assigned to the client node, would reduce load imbalance between the file servers. In certain embodiments the particular file server is the file server experiencing the least load. The method returns, to the client node in response to the request, an address associated with the particular file server, thereby enabling the client node to mount the particular file server to access files thereon. A corresponding system and computer program product are also disclosed.

A programmable apparatus for executing a function is disclosed. The programmable apparatus includes a physical interface configured to be connected with an external apparatus. The programmable apparatus also includes a function logic circuit configured to execute the function on the programmable apparatus. The programmable apparatus further includes a plurality of peripheral logic circuits, each of which is configured to connect the function logic circuit with the physical interface using a respective protocol. The programmable apparatus also includes a selector circuit configured to select one from among the plurality of the peripheral logic circuits to activate.

A reversible plug connector includes a plug housing having a housing contact disposed on an inner surface of the plug housing, a moveable plug insulator disposed within the plug housing, the moveable plug insulator having an upper surface and a lower surface opposite the upper surface with a metallic conductor exposed on both the upper surface and the lower surface. The moveable plug insulator is configured to be vertically displaced in response to the reversible plug connector being inserted into a receptacle connector such that a portion of the metallic conductor is brought into contact with a receptacle contact on the receptacle connector and another portion of the metallic conductor is brought into contact with the housing contact, and thereby the housing contact is electrically connected to the receptacle contact. A corresponding system is also disclosed herein.

Reversible connector interface

The present invention provides a method of generating a sequence of pseudo-random numbers which are difficult to predict. The method includes: (i) generating a plurality of candidate pseudo-random numbers by a respectively corresponding plurality of (differently structured) linear feedback shift registers; (ii) generating a 'selector number' from one or more additional linear feedback shift registers; and (iii) selecting a candidate number from the plurality of candidate numbers, based on the 'selection number' to produce a selected pseudo-random number for output.

Data is recorded such that the positions of data will be aligned in a traveling direction and a width direction of the storage medium. The medium travels in the traveling direction from a first to a second position as a certain wrap of a group of plural files in a first physical range between the first and the second positions. A head shifts from the certain wrap to another wrap in the width direction of the medium. The medium travels in the traveling direction from a third to a fourth position as the other wrap of a group of plural files in a second physical range between the third and the fourth positions. The plural files in groups on the certain wrap and the other wrap may be written in reverse order to each other after being once stored in a buffer.

Writing and reading data having multiple access patterns on tape media

The present invention provides a ring bus type multicore system including one memory, a main memory controller for connecting the memory to a ring bus; and multiple cores connected in the shape of the ring bus, wherein each of the cores further includes a cache interface and a cache controller for controlling or managing the interface, and the cache controller of each of the cores connected in the shape of the ring bus executes a step of snooping data on the request through the cache interface; and when the cache of the core holds the data, a step of controlling the core to receive the request and return the data to the requester core, or, when the cache of the core does not hold the data, the main memory controller executes a step of reading the data from the memory and sending the data to the requester core.
