Abstract: One embodiment of the present invention provides a system for accessing an encrypted file through a file system. During operation, the system receives a request to access the encrypted file. In response to the request, the system sends an encrypted file key for the encrypted file from the file system to a tamper-resistant module. Next, the tamper-resistant module uses a master secret to decrypt the encrypted file key to restore the file key, wherein the master secret is obtained from an external source by the tamper-resistant module. The system then uses the file key to access the encrypted file.

Abstract: An assembly structured to clean the head portion of a stethoscope comprising a housing including a path of travel along which the head portion passes during cleaning. A supply of cleaning fluid associated with a dispenser assembly is cooperatively disposed relative to an activating assembly. The activating assembly is operated in moveable engagement with the head portion, and activates the dispenser assembly when engaged by the head portion as it passes along the path of travel. The dispenser assembly delivers the cleaning fluid to an applicator assembly which distributes the cleaning fluid to the head portion and facilitates the cleaning thereof and removal of excess cleaning fluid there from. At least one disinfectant agent is dispersed within or comprises a portion of the housing and is formulated to be destructively effective against pathogenic bacteria, such as in the spore form, which is generally not affected by the cleaning fluid.

Abstract: An assembly structured to restrict contamination of individuals from association with the heads of stethoscope comprising a housing including a path of travel along which the head portion passes. Different embodiments include the dispensing of cleaning fluid or the delivery of protective barriers onto predetermined portions of the stethoscope heads, while passing along the path of travel. A dispenser assembly and a cooperatively disposed activating assembly are manually operated by moveable, driving engagement with the head portion passing through the housing. The activating assembly is thereby operatively positioned to activate the dispenser assembly when engaged by a head passing along the path of travel. Differently structured dispenser assemblies function to either deliver the cleaning fluid or individually dispense the barriers onto different heads, so as to either facilitate the cleaning or protective covering of exposed surfaces of the stethoscope heads, dependent on the embodiment utilized.

Abstract: A thermoplastic laboratory beaker that holds liquid in a reservoir portion of the beaker, in which the beaker includes a first upright, generally circular, outer sidewall and a second inner sidewall which are united at their upper limit height to form a lip edge or lip surface. The two sidewalls typically diverge from each other below the lip surface to create an air space between them. The outer sidewall extends downward a first distance D1 below the lip surface, and then usually bends outward to form a substantially planar supporting flange that at least partially supports the weight of said beaker on a laboratory surface. The inner sidewall extends downward a second distance D2 from the lip surface, and then bends inward to form a bottom wall for the reservoir portion that intersects the central vertical axis of said beaker, in which the inner sidewall and the bottom wall form the reservoir portion for holding a liquid.

Abstract: A machine-implemented system and method are described for removing interference between adjacent distributed-input-distributed-output (DIDO) clusters comprising. For example, a method according to one embodiment comprises: detecting signal strength at a first client from a main DIDO cluster; detecting interference signal strength at the first client from an interfering DIDO cluster; if the signal strength from the main DIDO cluster reaches a specified value relative to the value of the interference signal strength from the interfering DIDO cluster, then generating channel state information (CSI) defining channel state between one or more antennas of the first client and one or more antennas of the interfering DIDO cluster; transmitting the CSI from the first client to a base transceiver station (BTS) in the interfering DIDO cluster; and implementing DIDO precoding with inter-DIDO-cluster interference (IDCI) cancellation at the BTS in the interfering DIDO cluster to avoid RF interference at the first client.

Abstract: A system and method are described which enable planned evolution and obsolescence of multiuser wireless spectrum. One embodiment of such a system includes one or multiple centralized processors and one or multiple distributed nodes that communicate via wireline or wireless connections. The distributed nodes may share their identification number and other reconfigurable system parameters with the centralized processor. The information about all distributed nodes may be stored in a database that is shared by all centralized processors. The reconfigurable system parameters may comprise power emission, frequency band, modulation/coding scheme. The distributed nodes may be software defined radios such as FPGA, DSP, GPU and/or GPCPU that run algorithms for baseband signal processing and may be reconfigured remotely by the centralized processor. A cloud wireless system may be used wherein the distributed nodes are reconfigured periodically or instantly to adjust to the evolving wireless architecture.

Abstract: A computer-implemented method is disclosed including: receiving a broadcast signal containing a set of multiplexed multimedia channels; storing said multiplexed multimedia channels in a temporary storage buffer on a mass storage device; determining a point in said temporary storage buffer to begin demultiplexing and decoding a first channel responsive to a user request to view a particular program on said first channel in its entirety, said point indicating the start of said program on said first channel; and demultiplexing and decoding said first channel of said set of multiplexed multimedia channels from said point within said temporary storage buffer.

Abstract: A system and method are described for dynamically adapting the communication characteristics of a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”).

Abstract: Non-linear or linear precoding is used to create separate areas of coherence to different users. Limited feedback techniques may also be employed to send channel state information (CSI) from the plurality of users to the MU-MAS. In some embodiments, a codebook is built based on basis functions that span the radiated field of a transmit array. Additionally, the precoding may be continuously updated to create non-interfering areas of coherence to the users as the wireless channel changes due to Doppler effect. Moreover, the size of the areas of coherence may be dynamically adjusted depending on the distribution of users.

Abstract: A method of securely storing electronic information includes a step in which target electronically stored information is encrypted with a first encryption key and then partitioned into a first set of encrypted ESI partitions a subset of which is able to reconstruct the unpartitioned encrypted ESI. This first set of encrypted ESI partitions is then encrypted with a first set of user encryption keys to form a first set of user-associated encrypted ESI partitions that are made available to a first set of users. When access to the target electronically stored information is changed, the target electronically stored information is accessed and then re-encrypted with a second encryption key to form a second encrypted ESI. This second encrypted ESI is then partitioned and distributed to a second set of users.
