Title: Method for limiting amplifier input current to avoid low voltage conditions
Inventor: Roger David Serwy
IPC: H03G3/00
Filed: 2017-04-20
Abstract: A predictive brownout prevention system 20 may be configured to reduce the level of an audio output signal and thereby prevent power supply voltage drop or brownout. The system receives information indicative of the amplitude of an audio input signal, a condition of the power supply, and one or more of the following: 1) adaptive estimates of power supply conditions; 2) anticipated effects of power supply capacitance; and 3) condition of a load impedance. The system determines from the received information whether a brownout condition exists, responsive to which it applies selectable attenuation to the audio signal path to reduce an amplitude of the audio output signal in order to prevent brownout. This is done prior to propagation to the audio output of a portion of the audio input signal having the brownout condition. The battery impedance of the power supply may be monitored. The complex impedance of the loudspeaker load may be monitored.

Title: Fluid ejector
Inventor: DANIEL RICHARD MACE
IPC: B41J2/14
Filed: 2017-02-15
Abstract: A fluid ejector for ejecting discrete volumes of ejectant includes a body with opposing first and second surfaces. One or more nozzles are defined as conduits extending through the body between the surfaces to connect first and second orifices at the first and second surfaces respectively. The fluid ejector further includes a gas supply means having a gas outlet and an ejectant supply means. The ejectant supply means supplies the ejectant to the nozzles at a pressure above ambient via their supply orifices. The supply orifice is defined in a conduit's side or is the second orifice. Relative movement of the gas supply means and body exposes first orifices to the gas outlet allowing the gas supply means to supply gas at a pressure above ambient, wherein a pressure difference thereby created between the first and second orifices causes ejection of the ejectant from the nozzles through the second orifices.

Title: Encoding data arrays
Inventor: Sven Ola Johannes Hugosson
IPC: H04N19/96
Filed: 2018-12-03
Abstract: Encoding an array of data elements representing a spatial array of data (e.g. an image or image block), by: transforming the data array; representing the transformed data as a plurality of bit-plane arrays, each comprising an array of bits representing the value of the transformed array at a particular bit position/significance; and encoding the transformed data array in a fixed size bit packet by encoding the sequence of bit plane arrays from the most significant bit array down until the packet is full. Each bit plane array is encoded by subdividing the bit plane array into sections and encoding data 501 indicating when a section is newly active (the first in the sequence of bit-plane arrays to have a non-zero coefficient), then recursively sub-dividing all newly-active and active (a previous bit plane in this section was newly-active) sections 502. For each active section refinements bits 503may indicate the transform coefficients of identified active coefficients. Another method and apparatus is disclosed in which the data array transform includes a rounding operation configured to select rounding target values to ensure that each data element that is being transformed is mapped to a unique frequency domain coefficient.

Title: Constructing enterprise-specific knowledge graph
Inventor: BALAJI VASAN SRINIVASAN
IPC: G06F16/36
Filed: 2019-01-22
Abstract: A method of constructing an enterprise-specific knowledge graph involves receiving structured (e.g. tabulated) and unstructured (e.g. free text) data from an enterprise-specific source 410. The structured data may comprise text-field/value pairs, which are used to identify corresponding relationships which exist in a predefined relationship taxonomy 412. A second set of text-field/value pairs may be extracted from the unstructured data 414. Some of the second set of text-field/value pairs are identified as having a matching relationship in the relationship taxonomy 418. Others, with no matching relationship, are sequentially clustered 420 and relationships are assigned based on the clusters 422. A knowledge graph is constructed from the first set of text-field/value pairs and their identified relationships, and the second set of text-field/value pairs and their identified or assigned relationships 424. The structured and unstructured data may exist in tuples in a subject-predicate-object format, with the predicate element used in identifying a relationship. The knowledge graph may be enriched by adding additional tuples determined to be missing based on existing patterns.

Title: Detecting out-of-bounds violations in a hardware design using formal verification
Inventor: IAIN SINGLETON
IPC: G06F30/398
Filed: 2016-10-14
Abstract: A hardware monitor is used by a formal verification tool for detecting out‑oF‑bounds violations in a hardware design for a device operating in boot and normal operating states. It comprises: monitor and detection logic to repeatedly determine a current operating state of the hardware design and detecting when an instruction is fetched from memory; assertion evaluation logic to evaluate assertions of a formal property that compares a memory address of the fetched instruction to an allowable or unallowable memory address range associated with the current operating state to determine whether out-of-bounds violations have occurred. The current state is determined by monitoring control and/or data signals 608 to detect whether the boot is complete 610 and determining the boot or normal operating state accordingly, e.g. by setting 612 and clearing 613 a boot complete register. Hardware designs are implemented in hardware description language (HDL) e.g. register transfer level languages (RTL).
