The invention relates to a method for managing non-volatile memory space in a secure processor comprising a secure non-volatile internal memory, the method comprising steps of: selecting data elements to remove from the internal memory, generating, by the secure processor, a data block comprising the selected data elements, and a signature computed from the selected data elements using a secret key generated by the secure processor, transmitting the data block by the secure processor, and storing the transmitted data block in an external memory.

A valve for controlling cryogen egress from a cryogen vessel has a housing having a low pressure side and a high pressure side with a fluid path defined between. A valve element is interposed between the low pressure side and the high pressure side of the housing. A mechanism is provided for holding the valve element against a valve seat. The mechanism has a cam shaft that is rotatable to displace the valve element from its seat to open the fluid path.

The invention relates to a method of executing a secure application in an NFC device, the method comprising steps during which: a contactless link is established between first and second NFC devices, the first NFC device transmits by the contactless link an identifier of a secure processor of the first NFC device, the second NFC device transmits by the contactless link an application identifier, the secure processor transmits by the contactless link first authentication data allowing the authentication of the secure processor of the first NFC device, the second NFC device transmits to an application server the first authentication data, the application server transmits to an authentication server the first authentication data and second authentication data) to authenticate the application and authorizes the two NFC devices to execute the application only if the secure processor and the application are authenticated.
摘要:
A pre-assembled, pre-tested quench path outlet assembly for providing a cryogen egress path from a cryogen vessel. A quench valve (26) is mounted within a flange (28). A cryogen egress tube (32) is sealed in leak-tight manner to the flange, to define a cryogen egress path (40) extending through the cryogen egress tube, the flange and the quench valve. The cryogen egress path is closed by a burst disc (34). In use, the pre-assembled, pre-tested quench path outlet assembly is mounted onto the cryogen vessel such that thermal stratification of gas within the cryogen vessel under normal conditions causes a lower end of the cryogen egress tube to be at a temperature below the freezing points of common air components.

A burst disc replacement apparatus (100) comprises a magazine (122) that carries a first burst disc (232) and a second burst disc (234). A flow path (104) passes through the apparatus (100) for venting fluid. The first burst disc (232) is located in the flow path (104). A translation mechanism (112, 144, 146, 200, 214, 220, 222) is arranged to move the second burst disc (234) into the flow path (104) in place of the first burst disc (232) in response to an indication that fluid pressure at one side of the first burst disc (232) has exceeded a predetermined pressure corresponding to rupture of the first burst disc (232).
摘要:
A system that cleans boat bottoms, or aquarium windows, and also stimulates the skin, yet does not penetrate or break the skin. The cleaning or skin stimulation is accomplished by high speed high pressure liquid flow, through multiple orifices carried by an orifice plate, with all or most orifices positioned at preselected angles, rather than simply perpendicular or parallel. The angle positioning emits water or fluids in a tangential manner to cause flow in a circle or straight line. The multiple orifices cooperate and force the water in the same direction, so that the cleaning effect is greater than that of individual perpendicular flow. An inner shroud around the head briefly captures much of the water. The water is largely caught by a second outer shroud and returned to the pump. The return water flow creates a suction and force on the head towards the surface to be cleaned. Filters before and after the pump remove the debris from the water. The system is also suited to hot tubs, private or public, for refreshing bathing.

A radio frequency identification RFID system returns to a reader a string of bits which identifies a product or item. The subject RFID system is arranged to have one or more bits changeable, by bringing out from the chip one or more conductors, or by changeable internal memory. These conductors manage one or more bits on the chip. The chip has multiple external connections. One of the connections is made via the cover on a container, such as the cap on a drug bottle. If the cap is removed, the circuit is broken, or the tab is cut, and the message sent by the RFID is modified. This message modification is detected in the reader, and so tampering or premature opening prior to check out or to sale is detected. The cuttable tab circuit is also used in manufacturing, wherein an object tagged with an RFID chip and antenna, can have tabs on the RFID cut according to which stage of the manufacturing process is underway or has been completed. Cutting the tab reports the status of a product in the manufacturing process. Cutting selected tabs also modifies a tag to determine to which airport or gate a baggage item should be sent, or the bags status. Alternative to cutting is modification of the memory contents, using one of the non-volatile semiconductor memories, such as flash memory.

The invention relates to processes of making a composition having a host compound capable of accepting one or more bio-affecting guest compounds, and compositions formed by the processes. The processes comprise mixing, in any order: (i) a non-ionic surfactant selected from the group consisting of compounds having chemical structure (I) where “—CH—O—CH—” represents an epoxide group, where Ra and Rb are hydrocarbons that can be the same or different, where at least one of the Ra and Rb hydrocarbons includes an epoxide group within 3 carbons of the hydrocarbon attachment to contribute to the desired hydrolipid balance of 7-9, where Rc is hydrogen or a methyl group, and where Rd is a methylene group, and ethyl group, or a structurally equivalent link with a bond length range about the same as or shorter than that provided by an ethyl group, and having a hydro-lipid balance in the range 7-9; (ii) an amphoteric surfactant selected from the group consisting of organic compounds having the chemical formula NH3—R—COOH, where R is a straight, branched, or aromatic hydrocarbon structure having 6-24 carbons; (iii) a solvent for the amphoteric surfactant; (iv) an aromatic selected from the group consisting of compounds having at (I) least one aromatic five or six-member ring; (v) an aluminum cation; (vi) a Lewis acid that is not a Bronsted-Lowry acid; and (vii) a Bronsted-Lowry acid.
