Abstract: The present invention relates to the use of MT as a reducing system for the Msr enzymes and other oxioreductase enzymes which form similar intermediates. Specifically, the invention provides for a reduction in the level of oxidative damage in cells through an increase in levels of MT by administration of suitable compounds, resulting in an increase in the activity of the Msr enzymes.

Abstract: A biometric key (10) having a body or housing (11) incorporating a biometric sensor (17) uses a plurality of contacts (19, 20, 21) enabling the key to gain access to a facility. There is also provided a receptor (25) for receiving the biometric key (10), wherein the biometric key (10) and receptor (24) have contacts (19, 20, 21) and mating contacts (30, 31, 32), respectively, for communicating. The biometric key (10) can communicate biometric data acquired from a key operator to the receptor (25). The biometric key (10) can communicate with the receptor (25) when received in a first orientation and also when received in a second orientation where the contacts (19, 20, 21) are inverted from the first orientation.

Abstract: A mobile, hand-held fingerprint scanner is recharged by a data and power communication interface. The mobile, hand-held fingerprint scanner includes a rechargeable power supply and a data and power communication interface. The rechargeable power supply powers the fingerprint scanner during mobile use. In one example, the rechargeable power supply includes at least one rechargeable battery, a charging circuit, and a voltage regulator circuit. Data and recharging power is carried over the sane interface. A separate plug for power is not needed. The fingerprint scanner can then be inserted quickly and easily in a docking station as only a single data and power communication interface need be coupled. This is particularly advantageous in law enforcement applications where mobile use is important and safety can be compromised if a mobile scanner does not couple to a docking station quickly and easily.

Abstract: A hand-held fingerprint scanner having local storage of image normalization data is disclosed, as well as a method of manufacturing such a scanner. The image normalization data is representative of fixed pattern noise associated with the image sensor used in the fingerprint scanner. This data may be combined with the raw image data resulting in normalized image data. The image normalization data is stored in non-volatile memory where it can be transmitted to a host processor. Alternatively, the fingerprint scanner may include a normalization processor, allowing transmission of normalized fingerprint images to a host processor. Also disclosed is a fingerprint scanning system having remote fingerprint scanners with local storage of image normalization data.

Abstract: An access control unit interface between a fingerprint scanner and a host processor is described. A daughter card is coupled between the fingerprint scanner, various access control peripherals, and the host processor. The host processor can be any commercially available processor. The daughter card handles real-time and interactive access control events. The daughter card may include an access control interface processor. The access control interface processor may include a display interface module, a keyboard module, a Wiegand interface module, a finger detect interface module, a LED interface module, and a serial communication module.
