Abstract: A Bluetooth Low-Energy (BLE) transmitter is presented for used in ultra-low-power radios in short range IoT applications. The power consumption of state-of-the-art BLE transmitter has been limited by the relatively power-hungry local oscillator due to the use of LC oscillators for superior phase noise performance. This disclosure addresses this issue by analyzing the phase noise limit of a BLE TX and proposes a ring oscillator-based solution for power and cost savings. The proposed transmitter features: 1) a wideband all-digital phase locked loop (ADPLL) featuring an fRF/4 RO, with an embedded 5-bit TDC; 2) a 4× frequency edge combiner to generate the 2.4 GHz signal; and 3) a switch-capacitor digital PA optimized for high efficiency at low transmit power levels. These not only help reduce the power consumption and improve phase noise performance, but also enhance the transmitter efficiency for short range applications.

Abstract: Examples of the present disclosure describe smart sensor technology. In an example, a smart sensor module may connect to a sensor using two connectors. Similarly, an external device may connect to the smart sensor module using two connectors, such that, in a pass-through operating state, a signal from the sensor is passed through the smart sensor module to the external device, thereby causing the smart sensor module to appear as an ordinary sensor and enabling the external device to sense the signal from the sensor. In another example, the smart sensor module may have an alternate operating state, wherein additional functionality is enabled, including, but not limited to, communication with a controller, activation of a light emitting diode (LED) or other indicator, or the retrieval and/or storage of information. The operating state may be selected based on the manner in which the external device connects to the smart sensor module.

Abstract: Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.

Abstract: A timing display device is defined by an extended length of indicator lights having a first end, a second end, and at least one intermediate location. A controller communicates with the indicator lights for controlled activation of the lights in a set pattern in conjunction with a clock sequence.

The movement of the light activation includes a first and second projected color, wherein the first color is sequentially activated between the intermediate location and the two ends and the second color is sequentially activated from intermediate location towards the two ends, while overlapping the previously activated first color. The indicator lights may be light emitting diodes and the display may be affixed to a basketball backboard.
