For enhanced access control, a client includes a token in each read or write command sent to a block storage device. The block storage device evaluates the token to determine whether or not read or write access is permitted at a specified logical block address. For example, the token is included in the logical block address field of a SCSI read or write command. The client may compute the token as a function of the logical block address of a data block to be accessed, or a metadata server may include the token in each block address of each extent reported to the client in response to a metadata request. For enhanced security, the token also is a function of a client identifier, a logical unit number, and access rights of the client to a particular extent of file system data blocks.

Method and device for evaluating, simultaneously and with a single equipment, physical parameters such as the absolute permeability and the porosity of fragments taken from a fragmented artificial or natural porous medium.The porosity of the fragments is measured by means of pressure tests using helium or any other gas, according to a protocol known in the art. Chamber (1) in which they are contained is communicated with a tank (11) of known volume containing helium at a known pressure. At pressure balance, the value of the solid volume can be deduced. The rock envelope volume and the mass in fragments are also measured. The porosity of the samples and the density of the rock are determined by combining these measurements. Their permeability is then measured by immersing them in a liquid and by communicating the chamber with a liquid initially at a predetermined pressure contained in an accumulator (9) so as to compress the gas trapped in the pores of the rock. The values of the physical parameters are determined by modelling the evolution of the volume of liquid injected in the chamber and by means of an iterative adjustment.Applications: petrophysical measurements from drill cuttings or crushed cores for example.

Evaluation of a wireless device using a channel emulator is facilitated by validating a playback file; compensating for external loss; applying post processing changes; compiling the playback file; streaming playback file data to a channel emulator; and performing playback by the channel emulator. Validation is performed by operating directly on the user's editable playback file so that compilation of the playback file is not required for validation. User-supplied values indicative of the levels of external losses are used to automatically adjust the corresponding values in the playback file by the specified amount before the playback data is relayed to the channel emulator. Post processing changes indicative of alternate channel conditions may be used to augment or replace values in the playback file before the playback data is relayed to the channel emulator. The playback file is sequentially compiled as playback data is used by the channel emulator to allow playback to start sooner. Real-time streaming of playback data also allows an unlimited number of playback instructions to be processed within a fixed memory footprint. A power tracking loop detect changes in the transmit power level of a connected device during playback, and the channel emulator is automatically recalibrated to account for power level changes.
