Publication number: 20240120661Abstract: A modular radio frequency (RF) device includes N base units, each including a differential segmented array (DSA) tile with a support board and a two-dimensional (2D) array of electrically conductive tapered projections disposed on the support board. Neighboring pairs of the electrically conductive tapered projections form RF pixels. The N DSA tiles are arranged to form an RF aperture. The N base units are programmed to switch the RF aperture between a first operating mode and a second operating mode. In the first operating mode, the N base units are operated as at least two independent subsets with each subset operating as an RF transmitter or receiver independently of the other subsets. In the second operating mode all N base units coherently combine as a single phased array RF transmitter or receiver.Type: ApplicationFiled: December 20, 2023Publication date: April 11, 2024Inventors: Douglas A.

Publication number: 20230289502Abstract: A Register Transfer Level (RTL) representation is recovered from a netlist representing an integrated circuit (IC). The netlist is converted to a graph comprising nodes belonging to a set of node types and edges connecting the nodes. The set of node types includes an instance node type representing an electronic component and a wire node type representing signal transfer between components. The graph is converted to a standardized graph by replacing subgraphs of the graph with standardized subgraphs. An RTL representation of the standardized graph is generated by operations including building signal declarations in a hardware description language (HDL) from the wire nodes of the standardized graph and building signal assignments in the HDL from instance nodes of the standardized graph.Type: ApplicationFiled: May 16, 2023Publication date: September 14, 2023Inventors: Adam G.

Publication number: 20230191060Abstract: Apparatus (20) for fitting to the machine end of a tracheostomy tube (10) includes both an HME and a speaking valve (30). The HME includes two exchange elements (28, 29) at opposite ends of a housing (23) extending laterally of a coupling (25) for fitting on the tube. The speaking valve has a cylindrical sleeve (31) extending across the housing midway along its length and in line with the tube. The sleeve is rotatable about its axis and has two openings (36) on opposite sides that can be aligned with the exchange elements of the HME to allow gas to flow from the tube through the exchange elements, bypassing the speaking valve. When the patient wishes to speak, he twists and rotates the speaking valve to block flow to the exchange elements and instead to allow air to be inhaled via the valve.Type: ApplicationFiled: May 28, 2021Publication date: June 22, 2023Applicant: SMITHS MEDICAL INTERNATIONAL LIMITEDInventors: Steven Mark Tupper, Jamie Daniel Perkins, Steven James Field

Patent number: 11624938Abstract: An unobtrusive augmented reality (AR) system can be used to assist the wearer in every day interactions by projecting information from the contact lens display onto the retina of the wearer's eye. The unobtrusive augmented reality system includes a necklace and a contact lens display that are unobtrusive to the wearer and the wearer's surrounding environment. The necklace of the unobtrusive augmented reality system generates power and data for the contact lens displays. The necklace and contact lens display include conductive coils inductively coupled by a magnetic field. The inductive coupling allows data and power generated by the necklace to be transferred to the contact lens display. A projector in the contact lens display projects images generated from the data onto the retina of the wearers eye.Type: GrantFiled: April 22, 2021Date of Patent: April 11, 2023Assignee: Tectus CorporationInventors: Gregory David Miller, Brian Elliot Lemoff, Kuang-mon Ashley Tuan, Herbert John Kniess, Ion Opris, Michael West Wiemer, Drew Daniel Perkins

Publication number: 20210290368Abstract: An electronic intraocular device is implantable into the capsular bag of a wearer's eye. In some cases, the intraocular device may include a femtoprojector. The femtoprojector projects images onto the wearer's retina when the electronic intraocular device is implanted in the wearer's eye. Different haptic designs may be used to keep the femtoprojector in position. In some embodiments, an imager is contained in a contact lens worn by the wearer. Images captured by the contact lens imager may be relayed to the intraocular femtoprojector. In some cases, the intraocular device may include an electronic capsular tension ring with a femtoimager. The femtoimager may capture images of the wearer's retina, for example for purposes of monitoring eye health.Type: ApplicationFiled: April 20, 2021Publication date: September 23, 2021Inventors: Michael West Wiemer, Morrison Ulman, Drew Daniel Perkins
