International Classification:

G06K 710

US Classification:

235462

Abstract:

A method for scanning and decoding the symbols of a bar code label using a CCD image sensor viewing the bar code, and coupled to a signal processor and memory, wherein initially a start of scan (SOS) first level signal is sent from the processor to the CCD image sensor, a digital data signal representative of the bar code is read from the CCD sensor, and the representative data signal read from the CCD sensor is stored in memory. When the SOS signal is at a second signal level, the stored data is validated and decoded to determine if the representative data is valid or invalid. The SOS first level signal is immediately restarted in response to an invalid bar code data signal to recollect bar code data signals from the CCD sensor viewing the bar code so that the scanning steps are repeated, or the SOS first level signal is immediately restarted to re-scan the bar code symbols immediately after the data signal is found valid. Thus, the CCD data collecting scan rate is maximized.

US Classification:

4241391

Abstract:

The invention relates to isolated polypeptides and nucleic acids encoding polypeptides which comprise a tim-3 IgV domain and a tim-3 intracellular domain, wherein the polypeptides do not comprise a tim-3 mucin domain or a tim-3 transmembrane domain. In addition, the invention relates to methods of modulating immune responses in a subject, comprising administering to the subject a therapeutically effective amount of an agent that modulates tim-3 activity. Immune responses include, but are not limited to, immune tolerance, transplantation tolerance, Th1 responses and Th2 responses.
