Filed:

Apr 30, 2002

Appl. No.:

10/136655

Inventors:

Qiang Fu - Forest Hills NY
Sergei Petrovich Nikitin - East Setauket NY
Anatoly Viktorovich Masalov - Troitzk, RU

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.

12/894011

Inventors:

Qiang Fu - Irvine CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

A63F 9/24

US Classification:

463 7, 463 37, 463 38

Abstract:

A video game system is operable to receive user touch location information while a first user is holding a game controller and to determine a first user ID for the first user based upon the user touch location information. Thereafter, the video game system is operable to measure an instant acceleration of the game controller, to compare the instant acceleration to a first threshold value and to lock the game controller for use by the first user corresponding to the first user ID based on the comparison of the instant acceleration and the first threshold value.

BROADCOM CORPORATION - IRVINE CA

International Classification:

G06F 7/04

US Classification:

340 583

Abstract:

A vehicle control system includes at least one touch pad having a plurality of touch sensitive elements and processing circuitry communicatively coupled to the at least one touch pad. The processing circuitry is operable to receive touch pad input from the at least one touch pad, the touch pad input corresponding to a user's touch of at least some of the plurality of touch sensitive elements. The processing circuitry further processes the touch pad input to determine user finger characteristics. The processing circuitry further processes the user finger characteristics to identify the user via pattern recognition and alters at least one vehicle setting based upon the identified user. Vehicle settings may be one or more of entertainment system settings, navigation system settings, suspension system settings, seat settings, mirror settings, steering wheel settings, climate control system settings, suspension system settings, engine control system settings, lighting system settings, and communication system settings.

International Classification:

H01S 310

US Classification:

372 22

Abstract:

Intra-cavity and/or inter-cavity sub-resonators with dielectric coated mirrors have anti-reflection and high-reflection coatings to attain high efficiency third and higher order harmonics generation of laser radiation. Main-resonators and sub-resonators enhance the fundamental and harmonic oscillations, respectively, which result in high conversion efficiency of third harmonics and higher. Such improved lasing efficiency may be implemented in high power lasers for improved power performance to attain over 8 W of UV output power with a high repetition rate. The use of intra-cavity THG techniques provide high efficiency by using existing high intensities of the input fundamental frequencies available in the intra-cavity region of the laser to avoid damage to components of the laser, such as the laser crystal. The THG utilizes a double-pass and/or multi-pass arrangement, which results in about a 60% increase in output power compared to a single-pass configuration. Also, blocking of UV energy generated in a return pass is performed to eliminate damage by the UV to the components in the main cavity.

International Classification:

A61M 5/315

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.
