Latest Patents

One of Martin's latest patents is focused on the "Variable length coding of indices and bit scheduling in a pyramid vector quantizer." This invention enables improved encoding and decoding of a vector of coefficients by associating a vector element of a signed pyramid with an encoded value. The encoded value consists of a first portion that identifies a corresponding vector element of an unsigned pyramid and a second portion that characterizes sign values for nonzero components of the vector element. This approach allows computational constraints, such as word size, to apply to the unsigned pyramid instead of the signed pyramid, thereby extending the range of signed pyramid parameters operable within these constraints.

Another significant patent is the "FSM closure of generalized tree models." This invention utilizes Generalized Context Trees to assign a unique state from a finite set to any string. The method refines the generalized context tree into a refined generalized context tree with a finite state machine (FSM) property. This refinement occurs when the generalized context tree lacks the FSM property, ensuring a more efficient representation of a source usable within an FSM.
