Feb 14, 2006

Appl. No.:

11/355113

Inventors:

Jiang Hong - San Jose CA, US
Sam Wang - San Jose CA, US
Ke Wei - Sunnyvale CA, US

Assignee:

Ricoh Company, Ltd. - Ohta-ku Tokyo

International Classification:

G06K 5/00

US Classification:

235382, 235380, 2353825

Abstract:

An approach is provided for a smart card authentication solution utilizing dynamically configurable data to authenticate unrecognized smart cards and communicate with back-end systems not supported by a default environment. The data may be dynamically reconfigured by a user to reflect changes in the authentication environment such as a new smart card type, new data model on a card, or new remote authentication mechanism.

Appl. No.:

12/141705

Inventors:

Sam Wang - San Jose CA, US

Assignee:

Ricoh Company, Ltd. - Tokyo

International Classification:

G06K 15/00

US Classification:

358 114, 358 115, 399 79, 700 9, 700237

Abstract:

A printing device includes a user interface, a print module, memory and a device agent. The device agent is configured to modify usage information stored in the memory of the printing device. Based on values in the usage information, one or more processes operating on the printing device may be suspended. If so suspended, a user may contact an administrator who operates the device agent to modify the usage information, and permit the one or more processes to resume.

Inventors:

Jayasimha Nuggehalli - Union City CA, US
Sam Wang - San Jose CA, US

International Classification:

G06F015/00
G06F003/12
G06F009/44

US Classification:

358001150, 719327000

Abstract:

An approach for automatically customizing printer drivers generally includes installing a generic printer driver on a client. The client is configured to allow communications between the generic printer driver and a printing device. The generic printer driver automatically retrieves configuration data from the printing device and stores the configuration data on a non-volatile storage. The configuration data indicates one or more attributes of the printing device and allows data to be printed to the printing device via the generic printer driver. The approach allows a generic printer driver to be used with many different printing devices, thereby reducing development costs and installation overhead.
