Abstract: In an arrangement for transmitting power or data through a solid rigid substrate without penetrating the substrate, acoustic transducer components are mounted on the substrate by means of strain isolator elements which are welded or otherwise bonded to the substrate and providing an attachment surface to which the attachment interface of the acoustic transducer may be attached. The strain isolator element is of the same or similar acoustic impedance as the rigid substrate and may indeed be formed of the same material. Various geometries of strain isolator are disclosed, including a plain spacer block, and one comprising a stalk attached to the solid rigid substrate and topped by a disc in a ‘mushroom’ configuration.

Abstract: One method for managing encryption includes identifying an available or a secure mode. During restarts a passphrase must be entered in secure mode but not in available mode. Further, a master key is created for encrypting volume keys, where master and volume encryption keys are not stored in non-volatile memory (NVRAM) nor in disk storage. A half-key is created by encrypting the master key with a secure key, the secure key and the encrypted volume encryption keys being stored in disk storage. The half-key is stored in NVRAM only in available mode but not in secure mode. The master key is recreated during a restart when operating in the available mode by decrypting the NVRAM half-key with the secure key from disk storage. Further, the passphrase must be entered by an operator to recreate the half-key and the master key during a restart in the secure mode.

Abstract: In one embodiment, an apparatus for avoiding packet losses is provided. The apparatus includes a first communication device that is configured to receive packets of data over a network from a second communication device and to store information indicative of a sliding window that corresponds to a predetermined number of packets of data. The first communication device is further configured to determine a number of lost packets of data from within the sliding window in response to receiving the packet of data and to determine a maximum value from the sliding window. The maximum value corresponding to a maximum number of lost packets of data for a number of sliding windows. The first communication device is further configured to control the second communication device to adjust a bandwidth rate at which the packets of data are transmitted over the network based on at least the maximum value.

Abstract: There is disclosed a transducer apparatus for acoustic communications through a substrate at a predetermined center frequency, the apparatus comprising:—an active piezoelectric element for generating an acoustic signal; an intermediate layer, having a surface for accommodating the piezoelectric element, and having a first array of protrusions on a surface opposite the surface for accommodating the piezoelectric element; and a second array of protrusions at the substrate, wherein the active piezoelectric element is mounted onto the intermediate layer, and the intermediate layer is secured in position relative to the substrate such that the first array of protrusions faces the second array of protrusions such that the acoustic signal may propagate through the first and second arrays. There are further disclosed a method of mounting such an apparatus and a plate suitable for use in the transducer apparatus.
