Abstract: Systems and methods are described for efficiently meeting the needs of property buyers, sellers, and agents. Attributes of the user and of each property are combined and processed by a machine learning model. The output represents a prediction that a user will choose to view the property. Each property is ranked and displayed to the user. When the user selects a property, the interaction is used to update the machine learning model. In some cases, a natural language processing system identifies property and user attributes based on a natural language query. In some cases, a chatbot may respond to a natural language query in real time. The system may also be utilized to provide matching services for buyers or sellers to agents, or third party service providers, as well as matching buyers and sellers directly to each other, or user to other users for transaction, interaction and other needs.

Abstract: A system substantially updates all the phase shifter values of a phased array antenna by using two “global writes” to update these parameters to all phased-array transformation circuits simultaneously via a serial bus. Antenna elements, each controlled by a phased-array transformation circuit, are individually configured to transform phase and gain according to a register array. The register array has a local register group and a central register group, the local registers physically placed close in proximity to RF chains which each correspond to an element of array antenna, whereby each set of local registers control an individual antenna element and a central register controlling overall beam steering function. Gain values are hierarchically distributed. The apparatus is configured to efficiently elaborate phase shift weights into a submodule of a phase array antenna system with low noise and bandwidth.

Abstract: In one embodiment, a memory that is delineated into transparent and non-transparent portions. The transparent portion may be controlled by a control unit coupled to the memory, along with a corresponding tag memory. The non-transparent portion may be software controlled by directly accessing the non-transparent portion via an input address.

Each request may include a non-transparent attribute identifying the request as either transparent or non-transparent. In an embodiment, the size of the transparent portion may be programmable. Based on the non-transparent attribute indicating transparent, the decoder may selectively mask bits of the address based on the size to ensure that the decoder only selects a location in the transparent portion.

Abstract: Radio Frequency (RF) amplifier design with RFIC suffers gain variations from gain variations due to wafer process variations, temperature changes, and supply voltage changes. Three methods are proposed to achieve constant amplifier gain, either through on-chip wafer calibration, or self-calibration. Through automatic adjustment of amplifier bias current, the proposed methods maintain constant amplifier gain over process, temperature, supply voltage variations. Under the proposed Method 1, a constant transconductance Gm with enhanced gain accuracy is maintained via wafer calibration. Under the proposed Method 2, a constant transconductance Gm is maintained by time-domain averaging through different transistors. Under the proposed Method 3, a constant Gm*R or RF gain is maintained considering the impedance of a matching network of the RF amplifier.

The single stage combiner also has an adjustable isolation resistor for different power ratios. A structure of switchable branch characteristic impedance, switchable isolation resistor for the unequal combiner is proposed as the preferred embodiment. In one advantageous aspect, broader coverage angle in a single array module can be realized via an antenna diversity switch.
