Abstract: Embodiments provide an oxygen supply device having multiple operational states including a first state and a second state. In the first state, the oxygen supply device is controllable to a local control instruction such that the oxygen supply device can be operated by a user physically located within a proximity of the oxygen supply device. In the second state, the oxygen supply device is only controllable to a remote-control instruction such that the oxygen supply device can be operated by a user remote to the oxygen supply device. For example, the user can be located in an office remote to a location of the oxygen supply device, which, for example, may be placed at a patient’s home. In the second state, the user is enabled to control the oxygen supply device from a device associated with the user in the remote location.

Abstract: A method and apparatus for providing TCAM functionality in a custom integrated circuit (IC) is presented. An incoming key is broken into a predefined number of sub-keys. Each sub-key is sued to address a Random Access Memory (RAM), one RAM for each sub-key. An output of the RAM is collected for each sub-key, each output comprising a Partial Match Vector (PMV). The PMVs are bitwise ANDed to obtain a value which is provided to a priority encoder to obtain an index. The index is used to access a result RAM to return a result value for the key.
