Appl. No.:

10/136655

Assignee:

Excel/Quantronix, Inc. - East Setauket NY

International Classification:

G01B 902

US Classification:

356450, 356456

Abstract:

An apparatus and method to measure optical intensity and phase of one or several light pulses is described. The apparatus combines a spectrally resolved interferometric asymmetric single-shot optical autocorrelator and imaging spectrograph. The asymmetric design of the optical autocorrelator based on second harmonic generation eliminates time-direction ambiguity, while a spectrally resolved interferometric pattern allows the performance of self-check and self-calibration of the apparatus and substantially improves convergence, robustness and reliability of the computational retrieval algorithm.

US Classification:

604506, 604207

Abstract:

An injection device, which can be, e.g., an insulin pen, can capture and transmit injection and/or medicament information to another device, such as, e.g., a blood glucose meter. The injection and medicament information can include, e.g., time and date of injection, type of medicament injected, and dosage amount. The injection device can include a dial cap that can be rotated to select a dosage amount to be injected. In some embodiments, the dial cap can include a microcontroller with transmitter, a Hall effect sensor, and a ring magnet. In some embodiments, the injection device can include a medicament cartridge with a 1-wire EEPROM, which can have medicament information stored therein. Methods of operating an injection device are also provided, as are other aspects.
