An apparatus for sharing information between entities includes a processor and a trusted execution module executing on the processor. The trusted execution module is configured to receive first confidential information from a first client device associated with a first entity, seal the first confidential information within a trusted execution environment, receive second confidential information from a second client device associated with a second entity, seal the second confidential information within the trusted execution environment, and execute code within the trusted execution environment. The code is configured to compute a confidential result based upon the first confidential information and the second confidential information.

An EPROM emulator makes use of a simple device with a housing connected to a eprom header which serves to connect the device to a circuit board in conjunction with a microprocessor emulator. Inside the housing are paging and data select circuits and a set of SRAM which are used in place of a traditional EPROM to hold the programming information. To program the device, the EPROM simulator is connected to the circuit board in place of an eprom. A switch on the housing is then turned to place the device in programming mode. The same switch also determines how the device is programmed by accessing the appropriate data lines for the number of pages of EPROM memory which are being emulated. After the switch is properly selected, the emulator is programmed by sending the data through the eprom socket on the circuit board via the microprocessor emulator. After the device is programmed, the switch on the housing is turned to place the device in read-only mode so that it can simulate an EPROM. In addition to the external switch, there are internal jumpers which are set to determine the type of EPROM which is to be emulated.

Indicating fit status of a mask in communication with a respiratory assistance device is disclosed. Upon initiating a therapeutic gas delivery from the respiratory assistance device to the mask, one or more measurements from respective one or more sensors of the respiratory assistance device is received. A leakage value from these measurements is derived, and a mask fit index is assigned. This is based at least upon a correlation of the leakage value to a particular sub-range of predetermined leakage values that corresponds to the mask fit index. The particular sub-range of predetermined leakage values is one among a plurality of sub-ranges, which together comprises an overall mask fit range defined at least by an ideal mask fit region, a loose mask fit region, and a tight mask fit region. A mask fit status based upon the assigned mask fit index is output to an indicator interface.

A self-authenticating credit card includes an input device for entering a PIN. The PIN is accepted by a micro-controller that uses the entered PIN as an encryption key for decrypting stored account information. A portion of the account information includes data, that when decrypted, contains an image that is rendered on an integral display, with account information sent to a transaction terminal. A timer is used to limit access to account data while in the unlocked state.
