Abstract: Systems and methods for multi-source hidden-state fusion on edge devices. A processing system executes a state-space model, accesses a vector database in dynamic random-access memory, and maintains model state in on-chip static random-access memory. The system processes document chunks to form hidden states and computes a key for each chunk. Tuples pairing each key with a hidden state are stored in the database. For a received query, the system computes a query key and retrieves tuples by nearest-neighbor search using the stored keys and the query key. A fusion function computes a fused hidden state across the retrieved hidden states. The fused hidden state is loaded as the initialization state. The model processes the query tokens from that state and generates answer tokens as a function of the fused state and the query tokens.

Abstract: A wireless anti-static device is disclosed, including an electronic sensing circuit that measures the polarity and electrostatic potential of the subject relative to its surroundings. Ion guns of positive and negative polarities are able to transfer an arbitrary quantity and polarity of charge from the subject by ejecting ionized air molecules into the surrounding environment. A control unit is programmed to trigger the appropriate ion gun when a corresponding charge is measured on the body, in order to continually maintain the net charge on the body below a desired threshold. The subject is thus effectively grounded relative to its environment without requiring physical tethers to ground.

Abstract: A position sensor comprising a primary winding (26) for generating a magnetic flux, a first secondary winding (24.1) the number of turns of which increases in one direction, a second secondary winding (24.2) the number of turns of which increases in the opposite direction to that of the first secondary winding. Both secondary windings (24.1, 24.2) are subjected to the magnetic flux generated by the primary winding (26) whereby voltages are induced in the secondary windings. The sensor further comprises an element movable with respect to the secondary windings. The element is of a magnetic or conductive material and distorts, in its vicinity, the magnetic flux generated by the primary winding (26). By providing third and fourth secondary windings at right angles to the first and secondary windings it is possible to detect position in two dimensions.
