Abstract: Inventory monitoring systems can include one or more load cells, pressure sensors, and/or force sensors to detect objects on a surface in a storage unit, a communication interface, and one or more processors operably coupled to the one or more load cells and the communication interface. The one or more processors can be configured to receive measurements from the one or more load cells. The inventory monitoring system may identify an object using regression analysis and statistical inference techniques based on the measurements to generate an inventory of items stored in the storage unit, and provide an autonomous, real-time tracking of the inventory to a user via the communication interface.

Abstract: A wireless communication device comprises a frequency generation circuit employing a crystal oscillator operably coupled to a fractional-based synthesiser and a voltage-controlled oscillator. The fractional-based synthesiser utilises a ratio between an integer value and a fractional value to set a radio frequency signal of the voltage-controlled oscillator. An automatic frequency control scaling sub-system is operably coupled to a fractional-based synthesiser and configured to receive and use an AFC word to frequency scale the fractional value in a multiplicative manner to set a radio frequency supported by the fractional-based synthesiser. Preferably, an automatic frequency generation sub-system utilises Absolute Radio Frequency Channel Number and the cyclical nature of the fractional value. In this manner, a saving on hardware and software overheads associated with frequency channel selection for fractional-N type synthesizers can be made.

Abstract: A modulation system can switch between two modulation modes. In order to comply with limits on peak power in spectral bands outside the RF operating one the transmitter is required to ramp down to a condition of minimal power. To avoid fixed ramping and trailing bits, the transmitting signal is subjected to FIR filtering. The two FIR filters are primed with a sequence using a parallel input mode before serially entering the information data.
