  • Patent number: 10613787
    Abstract: Techniques for improving storage efficiency of a data storage system are provided. The techniques include (a) performing a testing operation to evaluate whether a test condition is satisfied for a filesystem having a plurality of subspaces, each subspace being provisioned with a respective amount of storage, each subspace of the filesystem being dedicated to storing different respective types of filesystem content, wherein the test condition indicates that a first subspace has available space in excess of a threshold percentage, (b) in response to determining that the test condition is satisfied for the filesystem, performing a reduction operation on the first subspace to remove a portion of storage provisioned to that subspace while retaining the removed portion for use by the filesystem, and (c) upon a second subspace reaching a fullness threshold, provisioning the removed portion to the second subspace and storing content of the respective type of the second subspace thereon.

  • Publication number: 20190033449
    Abstract: A laser ranging device includes a laser transceiving apparatus, a rotation apparatus, and a power supply control apparatus. The laser transceiving apparatus is used for transmitting a projection beam to a target to be measured and receiving a reflection beam reflected by the target to be measured. As there are no problems of the reflectivity of the reflector itself and the angle offset of the reflection beam, the light utilization is effectively improved. The rotation apparatus drives the laser transceiving apparatus to rotate by electromagnetic induction transmission, making the laser ranging device smaller in size. The power supply control apparatus supplies power to the rotation apparatus, increasing the service life of the laser ranging device, and the power supply control apparatus transmit data with the laser transceiving apparatus through photoelectric conversion.

  • Patent number: 9675155
    Abstract: A light transmitting device has a flexible elongated substantially flat band of high clarity light transmitting polymeric material. An LED is mounted by a mounting structure immediately adjacent but not embedded in an end of the band, and electrical wiring extends from the LED to a battery. The band is incorporated in a container (e.g. backpack, fanny pack, clutch) made at least partially of fabric so that light emitted from the band is visible from the exterior of the container. A battery and printed circuit board are mounted in the interior of the container, and an electrical switch for operating the LED is accessible from the exterior of the container. A flap stitched onto the front panel of the container covers the band and holds it in place but allows light to get through.

  • Patent number: 9534749
    Abstract: A slap wrist device includes a bottom strip having top and bottom surfaces with at least the top surface of thermoplastic material, a middle strip having top and bottom surfaces and of or coated with a thermoplastic material, and a top strip having top and bottom surfaces, at least the bottom surface being of thermoplastic material. A bistable spring is disposed between the bottom and middle strips, and a light emitting and elongated flexible light transmitting element is disposed between the top and middle strips. The bottom and middle strips are sealed together by high frequency (HF) welding along substantially their entire peripheries, and the top and middle strips are sealed together by HF welding along at least the majority of their peripheries. A battery casing, with or without an external safety light, or a fabric bag, may be mounted to an end of the device.

  • Patent number: 9488325
    Abstract: A light transmitting device is extremely adaptable and provides a great amount of light for a given battery power. A flexible elongated polymeric light transmitting element has first and second ends with at least one LED immediately adjacent (e. g. touching but not embedded in) one or both of the ends so that light is efficiently transmitted from an LED along the light transmitting element. At least one battery powers the LED. A module including a printed circuit board, electrical switch, and the LED and battery, is positioned within a housing having open ends so that one or both ends of the light transmitting element receive light directly from an LED. A number of button batteries, or a rechargeable battery with USB port, may be mounted on the module, and the circuitry of the printed circuit board may include an integrated circuit.

  • Patent number: 8957135
    Abstract: The present invention relates to a composite powder, preparation and use thereof. The composite powder according to the present invention is prepared by intimately mixing an irradiated or non-irradiated rubber latex with a slurry of inorganic particles in a ratio corresponding to that of rubber particles to inorganic particles in the composite powder according to the present invention, and then drying the resultant mixture. The composite powder according to the present invention comprises agglomerates composed of powdery rubber particles and inorganic particles, with inorganic particles being uniformly distributed either inside the agglomerats or both inside the agglomerates and on the surfaces thereof. The composite powder according to the present invention can be easily dispersed in plastic matrixes and thus can be compounded with plastics to produce toughened plastics and thermoplastic elastomers.
