    Abstract: Disclosed herein are techniques for computationally designing enzymes. These techniques can be used to design variations of naturally occurring enzymes, as well as new enzymes having no natural counterparts. The techniques are based on first identifying functional reactive sites required to promote the desired reaction. Then, hashing algorithms are used to identify potential protein backbone structures (i.e., scaffolds) capable of supporting the required functional sites. These techniques were used to design 32 different protein sequences that exhibited aldol reaction catalytic function, 31 of which are defined in the Sequence Listing. Details of these 31 different synthetic aldolases are provided, including descriptions of how such synthetic aldolases can be differentiated from naturally occurring aldolases.

    Abstract: A dual storage cell memory includes an array of dual storage cells, each of the dual storage cells containing a first memory cell and a second memory cell. The first and second memory cells are well known six-transistor static memory cells with the addition of transfer circuitry for transferring data directly from the internal data nodes of each of the memory cells to its corresponding complementary memory cell without requiring the use of the enable transistors or the bit lines associated with each of the dual storage cells.

    Abstract: A temperature and processing compensated time delay circuit of the type which can be fabricated in a monolithic integrated circuit utilizes a field effect transistor (FET) (12) connected to the terminals of a charged capacitor (14). A bias voltage connected to the gate of the FET (12) varies with temperature in a manner to compensate for the changes in current which flows from the capacitor (14) through the FET (12) due to changes in temperature. The bias voltage also varies from one integrated circuit to another in a manner to compensate for variations in FET threshold voltage caused by variations in the processing of the integrated circuits.

    Abstract: A portable, non-volatile read/write memory module includes a battery for providing standby power that is coupled to a monolithic integrated circuit. Five terminals of the module are removably connected to a host electronic system for transfer of data to and from the module. One of the terminals is a chip enable input that may optionally be used for providing operating power to the monolithic integrated circuit. The monolithic integrated circuit further includes control circuitry that may optionally be coded for providing a security feature for access to data stored in the memory module.
