A nasal cannula 1 for inclusion in medical apparatus that delivers a breathable gas mixture of helium and oxygen to a patient comprises a length 12 of high pressure narrow bore tubing having a proximal end region for connection to a high pressure source, a cylinder 2, of the breathable gas mixture at a junction 8. The length 12 of tubing has a distal end region connected to at least one nasal administration device 10. The distal end region of the length 12 of tubing has an orifice for the expansion of the breathable gas mixture.

A physical object comprises one or more memory circuits adapted to be read wirelessly by a reader device attached to or incorporated within the physical object. Data in the memory circuit is protected from access by an unauthorised reader. Data in the memory circuit is also adapted to identify an authorised bearer of the physical object. Moreover, data in the memory circuit is adapted to allow access to a specified asset or assets by the authorised bearer.
摘要:
Anti-counterfeit marking for a product, comprising: a tamper evident marker attached to or integrated with a product or packaging for a product and having a random mark; and an electronic memory element containing data about the random mark, the memory element being attached to or integrated with the product or packaging for the product in a tamper evident manner.
摘要:
This invention provides a processor 200, especially for use as the central processing unit of a memory tag 1200. The processor 200 has a minimal footprint in Silicon or other suitable material. It also is driven by the data that it receives. The processor includes a plurality 206, 212, 214, 224 of registers configured to receive in parallel data that are input to the processor, and to process in parallel the received data, and a micro sequencer and instruction decoder module 202 adapted to select two or more of the plurality of registers to receive the data that are input to the processor, and to control the processing of the received data by the end or more selected registers. A memory 1200 device utilising such a processor, and a method of processing instructions are also provided
摘要:
A first flow of air is compressed in a first air compressor associated with a gas turbine and is purified in an adsorptive purification unit which separates water vapour and carbon dioxide from the air. The purified first flow of air is further compressed to a pressure at least 5 bar higher than that at which it is purified in a second air compressor whose outlet pressure is independent of fluctuations in the power output of the gas turbine, is cooled in a main heat exchanger, is passed through an expansion valve, and is introduced into a higher pressure rectification column. A second flow of air is compressed in a third air compressor which is independent of the gas turbine. The compressed second flow of air is purified in an adsorptive purification unit by the separation of water vapour and carbon dioxide therefrom. The purified second flow of air is cooled in the main heat exchanger and is introduced into the higher pressure rectification column. The air flows are rectified in the higher pressure rectification column and an associated lower pressure rectification column operating at pressures above 2 bar. A nitrogen product is withdrawn from the top of the lower pressure rectification column and a liquid oxygen product from the bottom thereof. The liquid oxygen is revised in pressure to at least 25 bar by a pump and is warmed to ambient temperature in the main heat exchanger.

An improvement to a gaseous oxygen cycle in which refrigeration is provided by two expansion turbines each fed with nitrogen. In addition, some nitrogen is recompressed, returned though the main heat exchanger, condensed and used to form a liquid nitrogen product.
摘要:
Purified air, typically at its dew point, is introduced into distillation column 10 through inlet 2. Oxygen-rich liquid is withdrawn through outlet 6 and is introduced into the top of a mixing column 20. Nitrogen-rich vapor passes from the top of the distillation column 10 to the bottom of the mixing column 20. In the mixing column, there is a downward flow of liquid that becomes progressively richer in nitrogen and an upward flow of vapor that becomes progressively richer in oxygen. Liquid nitrogen is withdrawn from the mixing column 20 through outlet 28 and is returned to the top of distillation column 10 to provide reflux therefor. In addition, a mixed stream comprising oxygen and nitrogen is withdrawn from the column 20 as product or waste. The mixing column 20 is provided with a first condenser 30 at its top and a second condenser 40 which takes a vapor stream from intermediate the outlet 28 and the top of the column 20 and returns condensed liquid to the column 20. The second condensation is effected by heat exchange with boiling liquid taken from and returned to the column 10. An argon-enriched oxygen stream is withdrawn from the column 10 and is separated in a second distillation column 50 to yield an argon product.
摘要:
A memory tag comprises an array of non-volatile memory, means for inductively obtaining power to enable receipt of data from and transmission of data to a reader device, a processor operable to process received data and to generate data to be transmitted; and a hash co-processor configured to apply a hash function to data applied to it. The array of non-volatile memory includes an area of write only memory. Reader devices for use with such memory tags and methods of using such memory tags are also described.
摘要:
Methods, systems and machine readable medium storing a machine readable program for managing data stored on a contactless flash memory device are disclosed. A compiled version of a hierarchical data model defined using a high level data structure definition language is provided at a host unit. The host unit is operable to run on a host platform. The compiled version of the hierarchical data model is compiled for the host platform. A first representation of a first hierarchical data structure is received from a contactless flash memory device at the host unit via a contactless communication channel. The first hierarchical data structure is a first instantiation of the hierarchical data model. A second representation of the first hierarchical data structure is generated in accordance with the compiled hierarchical data model at the host unit.
