Abstract: A smart and secured system to receive packages from online shopping; automatically download list of incoming packages from one or multiple linked online-shopping accounts; provide navigational support to postal carriers and/or autonomous delivery; print receipts for validation; send encrypted confirmation to home-owners when any packages arrives; and implement an a. The system compromises of a secure box with a magnetic lock to store packages; a control circuitry, mini thermal printer and embedded processor to recognize and validate the arrived packages; a radio-frequency transceiver to wirelessly communicate with other electronic devices to notice information of the packages; and global positioning system (GPS) tracking tags for anti-theft protection.

Abstract: A method and apparatus for contactless measurement of the characteristics of patients' eyes and eyewear without using any reference device for scaling measurements. The non-contact system comprises of a measurement device having an array of proximity sensors for contactless distance measurement, which is embracing a mobile device having a digital camera, a processor, gyroscope or 3-axis accelerometer sensors, and wireless transceivers. The wireless transceivers support fast and real-time communication between the mobile device and the measurement device. The mobile device is configured to obtain information of distance between the patient face the measurement device at the same time as the digital camera is capturing images of the patient. Such distances assist the processor of the mobile device to re-construct actual eye and eyewear characteristics from the captured image of the digital camera.

Abstract: Sensitivity is a critical aspect of weather radar systems. Such systems not only detect atmospheric patterns but often need to precisely measure weak precipitation echoes. Embodiments of the invention use pulse compression techniques to increase the sensitivity of weather radar systems. These techniques can include sending two waveforms into a region of interest, where the second waveform is designed based on knowledge about the first waveform. Such systems can enhance the sensitivity of weather radars about 10 dB.
