  • Network architecture, methods, and devices for a wireless communications network
    Patent number: 12231284
    Abstract: Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

  • Analog resolution adjustment for CMOS image sensor
    Patent number: 11950002
    Abstract: Analog power savings is achieved by pre-charging only those pixels of a sensor array that are needed as determined responsive to any one of a power configuration, image size, image position of interest, desired/selected frame rate, desired/selected resolution, etc. To that end, the solution presented herein selects one or more sensor segments, each comprising a subset of pixels of the sensor array, and only pre-charges the pixels in the selected segment(s). In so doing, the solution presented herein provides a power savings proportional to the number of uncharged pixel circuits.

  • Methods and Apparatuses for Bottleneck Stages in Neural-Network Processing
    Publication number: 20230409883
    Abstract: Methods and apparatuses herein improve bottleneck-layer processing in neural networks. Example advantages include reducing the number of accesses needed to external memory, allowing processing to run in parallel in successive bottleneck layers, based on the use of partial convolutional results, and balancing the amount of “local” memory used for storing convolutional results against the computational overhead of recomputing partial results. One aspect of the methods and apparatuses involves co-locating arithmetic and logical operators and temporary storage in the same data path, with the approach yielding both higher performance and greater energy efficiency in the implementation of bottleneck layers for neural network processing.

  • RADAR SIGNAL FOR USE IN MOBILE COMMUNICATION EQUIPMENT
    Publication number: 20230246668
    Abstract: A wireless communications device that operates in a wireless communications system performs a radar function. This involves obtaining required radio frequency (RF) properties of a radar signal to be used for the radar function, wherein the radar function is one of a plurality of radar functions supported by the wireless communications device, each having a respective one of a plurality of different required RF properties. A transceiver of the wireless communications device is configured to transmit a predefined signal of the wireless communications system using time and frequency resources associated with the predefined signal of the wireless communications system and that satisfy the required RF properties of the radar signal. The configured transceiver is used to transmit the predefined signal of the wireless communications system.

  • Device and a method for stabilizing a web or a filament of ferromagnetic material moving in one direction
    Patent number: 7187532
    Abstract: A device and a method for stabilising a metallic object of magnetic material. The metallic object is transported along a transportation path or plane. The plane includes a transportation direction and is parallel to the longitudinal direction of the object therein. A sensor is arranged to sense the valve of a parameter depending on the position of the object with respect to the plane. An electromagnetic actuator is arranged to apply a magnetic force to the object in respone to the sensed position. The magnetic force has a force component directed transversely to the transportation direction and transversely to the plane.

  • Method and apparatus for implementing a camera mouse
    Patent number: 6783069
    Abstract: A mouse incorporating a camera captures an image of embedded data from a substrate under the mouse. The embedded data in the image is decoded to determine address or location information coded in the embedded data. Based on the decoded information and other user input signals, such as mouse button selection signals, the computer executes operations. The mouse also has a display controlled by the computer for providing visual feedback to a user. The display might generate an image of the substrate area under the mouse, making it appear to the user as if they are looking through the mouse directly onto the substrate. The display may also generate visual feedback regarding operations occurring in the computer, such as selection or other computer operations.

  • INK JET CARTRIDGE REFILL SYSTEM, KIT, STATION, AND METHOD
    Publication number: 20010013884
    Abstract: An ink refill system, ink refill station, ink refill kit, and method to replenish both pigment and/or dye-based inks in cartridges of ink jet printers, plotters, copiers, and fax machines. A number of embodiments are described. The principal embodiment is a refill kit characterized by a spring clip assembly removably mountable on a cartridge. The clip assembly has mounted upon it a member which is sealingly connectable to the vacuum relief valve port or bubble generator on the bottom of the ink jet cartridge, an internal channel of the clip assembly connecting the bubble generator port and sealing member to a receptacle which removably connects to a flexible ink refill bottle, which bottle is adapted to both inject ink into, and remove excess air from, the cartridge via the bubble generator port. A permanently mountable footplate embodiment of this system is also described.

  • Plate heat exchanger
    Patent number: 5988269
    Abstract: A plate heat exchanger for two or more flowing media may according to the invention be designed so that the front and rear cover plates (1, 8) of the exchanger act as channel defining walls for a flowing heat exchanging medium, and so that the tube connections at the inlet and outlet ports (10-13) can be established in a common plane. This is obtained thereby that the front and rear cover plates (1, 8) together with the adjacent first (2) and last (5) channel forming plates define distribution channels (18) crossing the direction between adjacent inlet and outlet ports.

  • Method for opening, refilling and sealing a cartridge
    Patent number: 5572852
    Abstract: A kit for opening and sealing a cartridge having an interior ink reservoir coupled to an access port extending from a reference surface comprises a rigid plunger, a plate and a rigid spherical plug. The plate has one or more regions of varying thickness and a bottom surface which is complementary to the reference surface on the cartridge. The bottom surface of the plate may be matched to the reference surface of the cartridge in two distinct orientations such that a sealed access port may be opened, refilled and sealed with a rigid spherical plug by extension of the plunger through the plate in each orientation to a depth determined by the length of the plunger, the thickness of the plate in each orientation, the depth of the access port in the cartridge, and the diameter of the spherical plug.

  • Method for refilling ink jet cartridges
    Patent number: 5488400
    Abstract: A method of refilling an ink jet cartridge with ink. The cartridge has a housing which encloses an internal ink reservoir extending between top and bottom ends thereof, an ink fill aperture extending through the housing near its top end, and a means for sealing the ink fill aperture. The cartridge further includes a bladder in the reservoir, an air port affixed to the top of the housing, and a spring means which biases the bladder toward a minimum volume state. According to the method, the cartridge is positioned with its top end above its bottom end, the ink fill aperture is unsealed, and the air port is sealed. The bladder is inflated to establish an internal volume in a predetermined range. Ink is then injected into the reservoir through the ink fill aperture. The ink fill aperture is then sealed, and the air port unsealed.
