Title: Configurable cashbox
Inventor: MALDANIS ALGERT J
IPC: G07B15/00
Filed: 1999-04-12
Abstract: A cashbox (100) having a configurable note to coin storage area ratio is disclosed. Accordingly, the cashbox (100) may be adjusted to accept a larger or smaller number of notes and a smaller or larger number of coins, respectively, depending on the circumstances of deployment of the configurable cashbox (100). Preferably, the note storage area (130) is adapted to accept and retain notes in a tight stack suitable for easy removal and machine sorting and/or counting. In a preferred embodiment, the configurable cashbox (100) is secure in that the cashbox (100) locks into a housing (800) with only limited access provided to the note and coin storage areas (130, 140) to allow deposit of cash in the cashbox (100). In order to remove the cashbox (100) from the housing (800), access to the note and coin storage areas (130, 140) is secured such that once the cashbox (100) is independent from the housing (800) any unauthorized access to the storage areas (130, 140) is easily detectable. Preferably, to aid in tracking individual cashboxes (100) and/or for use in accounting for the monies collected in a particular cashbox (100), the cashbox includes a machine readable identification (113).

Title: System and method for reducing inter-pixel distortion by dynamic redefinition of display segment boundaries
Inventor: WORLEY W SPENCER III
IPC: G09G3/20
Filed: 1999-05-07
Abstract: A method for writing data to a display (500), wherein logical segments (512, 502, 504, 506) are dynamically redefined to displace the intersegment boundaries (514, 508, 510) and delocalize inter-pixel electrical fields occurring across the intersegment boundaries (514, 508, 510). One particular method includes the steps of grouping rows of a display (500) to define the logical segments (512, 502, 504, 506), writing data to at least one of the logical segments (512, 502, 504, 506), regrouping the rows of the display (500) to redefine the logical segments (512, 502, 504, 506), and writing data to at least one of the redefined segments (512, 502, 504, 506). Code contained in an electrically readable medium, for example a memory device, causes a display driver circuit to write data to a display in accordance with the described methods.

Title: Auto-recoverable auto-certifiable cryptosystems with unescrowed signature-only keys
Inventor: YOUNG ADAM LUCAS
IPC: G09C1/00
Filed: 1999-12-20
Abstract: A method is provided for digital signature infrastructure that provides publ ic keys (1005) which are effective only for verifying digital signatures, and a re not effective for encrypting information in a way that is unrecoverable by l aw- enforcement entities. The method can be implemented in software, thus avoidi ng the need for tamper-proof hardware. The method has the property that signing  private keys (1010) are not escrowed, since the corresponding public keys cannot be used effectively for criminal communications. As a result no one c an impersonate the user; alternately users can prove impersonations. Furthermor e, the system is shadow public key resistant. A shadow public key is a public k ey which is not escrowed and which can be used for untappable communications. Therefore, the method presented here cannot be used to publish public keys which are not escrowed. All information displayed by the certificate authorities, and even the digital signatures of users, are shadow public key  resistant. The present invention is useful for any application that requires  that messages be verifiably authentic, and is particularly applicable to bei ng used in a national public key infrastructure (PKI), since it is very scalabl e. It can be combined with Auto Recoverable auto certifiable systems to give ac omplete solution to encryption (confidentiality) and signature (authentication) in the context of escrow key systems.

Title: Fuel cell system using pressure swing adsorption and variable oxygen enrichment
Inventor: ST PIERRE JEAN
IPC: H01M8/04089
Filed: 2001-09-21
Abstract: In a fuel cell system operating on oxygen enriched air, an air compressor or other source of compressed air provides pressurized air to a pressure sing adsorption unit at a desired adsorption pressure. System efficiency and fuel cell output voltage characteristics can be improved by varying the air compression in relation to the electrical load applied to the fuel cell. Decreasing the air compression at low applied loads reduces the parasitic energy loss of the air compressor and reduces the variation in output voltage observed when varying the applied load.
