  • Patent number: 9937765
    Abstract: Methods and systems for adapting an automobile suspension in real-time may include a radar module reading a surface topology ahead of a vehicle. A processor may convert an output signal of the radar module into a suspension input signal that corresponds to an amount by which a wheel suspension device of the vehicle should be adjusted to counteract the surface topology. The processor may adjust a mechanical attribute of the wheel suspension device in real-time based on the suspension input signal. In an embodiment, the processor may be configured to calculate the amount by which the wheel suspension device should be adjusted based on a speed of the vehicle and a size of the surface topology. In one embodiment, the radar module may include a gimbal mount configured to provide vertical and horizontal visibility to the radar module.

  • Patent number: 9607369
    Abstract: A moving wafer imaging system processes wafer images to remove motion and focus blur by performing a blind deconvolution to determine an approximate point spread function. The approximate point spread function, estimated image noise and a Gaussian point spread function are used to compute a weighted point spread function. The weighted point spread function is used to filter out motion focus blur. Noise is then removed with a low-pass filter.

  • Publication number: 20160317070
    Abstract: A method for non-invasive blood glucose monitoring with a wearable device may include illuminating, with an electromagnetic source module of a wearable device, an area of skin of a user. The method may include measuring a scattered electromagnetic energy reflected from the area of skin with an electromagnetic receiver module of the wearable device. The method may include calculating, with a processor coupled to the electromagnetic receiver module, a blood glucose level in response to the measurement of the scattered electromagnetic energy reflected from the area of skin. The method may include communicating the blood glucose level to an information handling system. The electromagnetic source module may include a photodiode or a microwave module. The information handling system may include an application configured for a smart phone, tablet, or computer. The information handling system may include a memory configured for storing a historical record including multiple blood glucose levels.

  • Patent number: 7024085
    Abstract: Optical systems are disclosed which include one or more components such as an optical multiplexer, an optical demultiplexer, and, an optical amplifier. An optical device is included in the optical system and is configured to communicate with the optical component(s). The optical device includes a substrate proximate to which is disposed a first waveguide array. A second waveguide array is also provided that is disposed proximate the substrate so that a portion of the second waveguide array intersects a portion of the first waveguide array at a predetermined angle, so that a junction is formed. An index of refraction associated with the junction can be varied so that desirable effects can be implemented concerning optical signals transmitted through the waveguides.

  • Patent number: 6778736
    Abstract: An optical device with at least one junction formed by an intersection of at least two waveguides may be used to tap, and/or attenuate an optical signal. The waveguides may be formed from various materials such as polymers and other combinations of monomers. Internal reflection produced at each junction between the waveguides in response to heating from a thin film electrode will direct a portion of an optical signal from one of the waveguides to another waveguide. Internal reflection at each junction may be used to selectively tap and/or attenuate power level of an optical signal.
