Abstract:
Systems and methods for registering fingerprints, setting a login method for an application, and logging into the application are provided. In the registration phase, the system receives a fingerprint signal, which is assigned to one of the many finger related data. In the phase which sets the login method, the system detects a login-signal, which comprises an identity, a password, and a command to execute the application. The system commands the display of the fingerprint related data and receives a selection message corresponding to one of the finger related data. The system assigns the application, the identity, the password to the selected fingerprint related data. In the login phase, the system receives the fingerprint signal and thereby, retrieves the corresponding application, the identity, and the password as well. The system generates a start signal comprising the identity, the password, and the command to execute the application.
Abstract:
Two concentration techniques, adsorption and electrodialysis, are combined to enrich lithium ions in brine from a level of several ppm to about 1.5%. At beginning brine is subjected to an adsorption, so that Li content is increased to 1200-1500 ppm, followed by two stages of electrodialysis in series to increase Li ions to about 1.5%. Li depleted solution from the second stage of electrodialysis having a Li content of 1200-1500 ppm is recycled to the first stage of electrodialysis as a feed. Li depleted water from the first stage of electrodialysis is subjected to a residue recovery electrodialysis to form a Li enriched solution of 1200-1500 ppm, which is also recycled to the first stage of electrodialysis as a feed. Li depleted solution from the residue recovery electrodialysis is recycled as a feed of the adsorption, so as to sufficiently recover Li ions from brine.

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 low-power crystal-controlled CMOS oscillator wherein a long and wide additional transistor is provided in the first stage of the output amplifier. This prevents the output amplifier from diverting too much current from the primary amplifier stage during start-up.

Abstract:
A nonvolatile static random access memory cell (10) includes a pair of cross-coupled transistors (12, 14) which function as a bistable circuit to store data states. Variable threshold transistors (36, 41) are respectively connected in series between the driver transistors (12, 14) and load devices (48, 50). A control node (40) is driven to a high voltage state to cause one of the variable threshold transistors (36, 41) to be driven to have a higher threshold voltage and thereby store the data state held in the cross-coupled transistors (12, 14). The data state is thus stored in nonvolatile form. Upon recall the memory cell (10) is reactivated and the threshold differential between the variable threshold transistors (36, 41) causes the driver transistors (12, 14) to be set at the stored data state. The data recalled by the memory cell (10) is in true rather than in complementary form. The variable threshold transistors (36, 41) are reset by driving the power terminal V.sub.cc to a high voltage state to reestablish common threshold voltages for the variable threshold voltage transistors (36, 41).
Abstract:
An integrated circuit memory cell (10) having a bit line (12), a word line (14) and a cell voltage supply (26) is provided. The integrated circuit memory cell (10) includes a first clock line (34) and a second clock line (36). A first transistor (20) is interconnected to the bit line (12) and the word line (14) for providing access to the memory cell (10). A second transistor (22) is interconnected to the cell voltage supply source (26) and to the first transistor (20) thereby defining a first node (S). The second transistor (22) provides a charging path from the cell voltage supply source (26) to the first node (S). A capacitor (30) is provided and interconnects the first clock line (34) and the second transistor (22). The interconnection between the capacitor (30) and the second transistor (22) defines a second node (K). The capacitor (30) provides a coupling path between the first clock line (34) and the second node (K) for conditionally supplying a voltage from the first clock line (34) to the second node (K) to render voltage at the second node (K) higher than the cell voltage supply source (26). A third transistor is provided for the memory cell (10) and is interconnected to the first node (S) and the second node (K) and the second clock line (36). The third transistor (24) provides a charging path between the second clock line (36) and the second node (K) for conditionally maintaining a voltage at the second node (K).
