摘要:
An apparatus and method are disclosed for detecting whether a device has been opened. A first radio frequency identification (RFID) tag is installed in the package, typically during manufacturing. A first component is included in the first RFID tag. The first component modifies a power source to the first RFID tag in response to the package being opened after the first RFID tag is installed. The first RFID tag indicates a first event in response to the power supply being modified.

A security device watches over the secure functionality in a computer system. This “watcher” security device may be integrated within the computer system or may be separate from it. The security device queries the secure functionality to determine whether the state of the secure functionality is acceptable. If no satisfactory state exists, or if no response is received, then a signal is transmitted. The signal may be auditory (a buzzer) or visual (a flashing light) in order to signal to any user that the secure functionality has been compromised. Optionally, human input devices may be disabled, or a monitoring service notified, in conjunction with or in lieu of the signal. If the secure functionality includes a secret shared between the secure functionality and the user, then the security device may signal the secret. For example, where the secret is visual, the security device may display the secret. Where there is more than one element of secure functionality in the computer system, the security device may separately watch and report on more than one element of secure functionality. The security device may also display status information regarding the computer system. Some or all of the security device may be distributed via a trusted distribution infrastructure.

A security key, such as an encryption key, is generated so as to make it more difficult for eavesdroppers to identify the key. Specifically, a cryptographically secure random number generator generates a random bit sequence that is included in a seed. This random seed is provided along with a negotiated master secret to a key generation module. The key generation module may implement a pseudo random function that is in accordance with the Transport Layer Security (TLS) protocol or the Wireless Transport Layer Security (WTLS) protocol. This key may then be used to encrypt a plain text message to form an encrypted data packet. The encrypted data packet also includes the random seed in unencrypted form. The encrypted data packet may be transmitted over a public network to a recipient with reduced risk of eavesdropping.

A cable connection for connecting a cable 9 to an underwater installation 7 comprises a connector (2, see FIG. 2) for connection to an end of the cable 9, the connector having at a first end engagement means for engaging with the installation 7, a tether (4, see FIG. 2) which in use has a first end attached to the connector and a second end attached to the cable at a distance from said end of the cable and guide means (12, 13, 14) located proximate a section of the cable adjacent said end of the cable so that in use said section is substantially restrained by said guide means at a predetermined angle with respect to the engagement means.
摘要:
An approach is provided for supporting multi-media conferencing. Textual information (e.g., text associated with a presentation) is received for display during a conference session to multiple participants. For a particular participant, configuration information corresponding to the participant specifies language assistance for the textual information. Language assistance involves augmenting the textual information according to the configuration information for comprehension of the textual information by the particular participant. In one embodiment, the augmented textual information includes language translation of the textual information. Additionally, the augmented textual information can encompass definitions of terms, including acronyms. The augmented textual information is forwarded for display to the participant during the conference session.
摘要:
A vehicle suspension assembly includes a device for securing an axle to a selected suspension component. A seat member that is received between the axle and the suspension component includes an axle adaptor as part of the seat member. A first portion of the seat member is received between the axle and the suspension component. A second portion of the seat member extends away from the first portion and includes at least one support surface for supporting a brake component relative to the axle. In one example embodiment, the seat member includes an integrated brake carrier.

A subsea separation device for use in separating a pair of stabplate connector plates, the subsea separation device comprising a first engagement member adapted to engage, in use, a first one of the connector plates, or a component rigidly secured thereto, a second engagement member adapted to engage, in use, a second one of the connector plates or a component rigidly secured thereto, and drive means operable to urge the first and second engagement members apart and so urge the connector plates apart.
摘要:
A security tag comprising at least one overt data carrier (10), and at least one covert data carrier (25), the covert data carrier comprising a ring (25) that is formed around the overt data carrier (10). The covert data carrier (25) is invisible to the unaided eye when lit with visible light, but visible when illuminated with other light, for example UV light.
摘要:
A brake caliper has a brake pad having a backplate with a friction material attached to one side and a loading face on an opposite side. The caliper further includes a piston that applies a force to the loading face. The brake pad is releasably attached to the piston, thereby eliminating a separate brake pad retaining structure in the caliper.
摘要:
A co-axial wear adjuster and wear sensor for a brake caliper includes a sleeve having an external tooth form engageable with a toothed adjustment wheel of a brake tappet. The sleeve rotates with the tappet and is threaded to engage a relatively non-rotatable, but axially movable, bolt. A wear sensor is partly within the sleeve and has a plunger operably engaged with the bolt. The bolt may be tubular to carry a screw-threaded head whereby a position of the plunger may be set.
