摘要:
A system and method to support platform firmware as a trusted process. Measurement of a trusted portion of original firmware are measured by a core root of trust measurement (CRTM). The measurement is stored in a secure manner during pre-boot. During operating system (OS)-runtime, requests are made to access an unqualified current version of firmware corresponding to a secure execution mode. A portion of the current firmware analogous to the trusted portion is measured. The measurements of the trusted original portion and unqualified current portion are compared to verify they match. If they match, it indicates that the current portion and the trusted portion are one in the same. Thus, the current portion of firmware is trustworthy. Accordingly, the firmware may be executed as a trusted process. Embodiments employ locality to enforce the trusted process. The use of locality prevents unqualified users (i.e., software) from accessing data stored by trusted firmware.

Fluorescent probes that have binding affinity to ribosomes. The fluorescent probes are useful tools for identifying small molecules that bind to the 50S or 30S subunits of the bacterial and other ribosomes and serve as novel ribosome inhibitors. These probes are also useful for determining the interactions between a specific ligand and the ribosome.

The present invention relates to hepatitis A vaccine, especially to a lyophilized attenuated hepatitis A vaccine which can be stored at ambient temperature for extended periods of time, and to a method for producing the same. The present invention further relates to a stabilizer for lyophilized live vaccine and its use in improving thermostability of lyophilized live vaccine during lyophilization processing and storage period after lyophilization.

A mouse with infrared remote control function comprises: an optical encode control circuit, a microprocessor circuit, a wire driver circuit of the transmitting part, an infrared modulating transmitter circuit, an infrared receiving demodulation circuit, a wire driver circuit of the receiving part, an interface switching circuit, a receiver/transmitter interface circuit and a power circuit (it can be switched off) for supplying the power circuit to the said optical encode control circuit, microprocessor circuit, infrared modulating transmitter circuit. Besides a single-purpose mouse with infrared remote control function is provided by the present invention, by using the interface switch circuit and automatic switch circuit, a dual-purpose mouse with both compatible infrared remote control function and compatible cable control function can be implemented.
摘要:
A micro-size LED-like optical element has an n-contact, a p-contact, and an optical active structure connected between the n-contact and the p-contact for generating light when forward biased and for detecting light when reverse biased. The optical active structure has a diameter of about 20 &mgr;m or smaller. When the the optical active structure is forward biased, it forms a micro-size LED (&mgr;LED). When the optical active structure is reverse biased, it forms a micro-size detector (&mgr;detector). An array of the micro-size optical active structures may be used as a minidisplay, a detector, or a sensor (when each structure is separately wired), or as a hyperbright LED (when the structures are wired to turn on and off simultaneously). Alternatively, a hyperbright LED may be obtained by forming a plurality of micro-size holes extending into an LED wafer.
