  • Publication number: 20200138190
    Abstract: A pullout cage apparatus is provided which is comprised of a base frame removably mounted to a pair of robust drawer slides. The drawer slides are coupled to each other by a pair of cross braces, which are in turn mounted to the base of a cabinet frame. A retainer cage is rigidly mounted to the base frame. The retainer cage supports a plurality of adjustment brackets, which allow adjustment of a face plate.

  • Patent number: 10642505
    Abstract: This disclosure provides techniques for managing memory which match per-data metrics to those of other data or to memory destination. In one embodiment, wear data is tracked for at least one tier of nonvolatile memory (e.g., flash memory) and a measure of data persistence (e.g., age, write frequency, etc.) is generated or tracked for each data item. Memory wear management based on these individually-generated or tracked metrics is enhanced by storing or migrating data in a manner where persistent data is stored in relatively worn memory locations (e.g., relatively more-worn flash memory) while temporary data is stored in memory that is less worn or is less susceptible to wear. Other data placement or migration techniques are also disclosed.

  • Patent number: 10642748
    Abstract: This disclosure provides techniques hierarchical address virtualization within a memory controller and configurable block device allocation. By performing address translation only at select hierarchical levels, a memory controller can be designed to have predictable I/O latency, with brief or otherwise negligible logical-to-physical address translation time. In one embodiment, address transition may be implemented entirely with logical gates and look-up tables of a memory controller integrated circuit, without requiring processor cycles. The disclosed virtualization scheme also provides for flexibility in customizing the configuration of virtual storage devices, to present nearly any desired configuration to a host or client.

  • Patent number: 10552085
    Abstract: A host stores “context” metadata for logical block addresses (LBAs) in a manner tied to physical location. Notwithstanding log-structured or copy on write processes, the host is then provided with immediate context when the host is called upon to assist a memory controller with data identified by physical location, for example, for memory reconfiguration, garbage collection, wear leveling or other processes. The metadata for example can provide the host with insight as to which data may be moved to enhance performance optimization and where that data can be placed. In one embodiment, the host writes back one or more references that span multiple layers of indirection in concert with write of the underlying data; in another embodiment, the context can point to other metadata.

  • Patent number: 10251480
    Abstract: Disclosed is a pullout apparatus having side access and designed for simple, adjustable, and accurate installation within a pre-existing cabinet space. The apparatus, slidably mounted within the cabinet space, comprises a top slide assembly mounted to a cabinet carcass and a drawer box. The drawer box is automatically centered on a base slide box. The base slide box is comprised of a slotted template slidingly engaged with a frame, where the frame is mounted to the cabinet carcass. Slide rail assemblies connect the slotted template to the frame. A pin block on the underside of a fixed shelf of the drawer box automatically centers the drawer box on the slotted template. A face plate adjustment mechanism provides for three dimensional alignment of the face plate with surrounding cabinets. An alternate embodiment comprises a mounting bracket providing three dimensional adjustability of the upper drawer slide.

  • Patent number: 10121613
    Abstract: A keyswitch device includes a base plate, a membrane circuit board, a light source, and a keyswitch assembly. The membrane circuit board is disposed on the base plate and includes a reflective film layer, a transmissive film layer, and a light guide spacer. The reflective film layer is located on the base plate. The transmissive film layer is located over the reflective film layer. The light guide spacer has an accommodating space. The reflective film layer and the transmissive film layer are respectively located at opposite sides of the light guide spacer. The light source is disposed between the reflective film layer and the transmissive film layer and located in the accommodating space. The keyswitch assembly is disposed on the membrane circuit board.

  • Patent number: 10111521
    Abstract: A rotary shelf assembly for a blind corner cabinet is provided. The apparatus is easily reconfigured to accommodate left and right-hand configurations and does not contact the partitions of the cabinet during stowage or deployment. The apparatus is comprised of a center pole secured to a cabinet frame with a universal frame bracket. The frame bracket has a set of opposing flanges attached to a base through which the center pole extends. A rotary coupling is secured to the base of the frame bracket. A rotary support engages the rotary coupling and rotates about the center pole. A shelf is adjustably and slidably attached to the rotary support by a set of slide assemblies. More than one shelf can be independently rotated about the center pole from a stowed position to a rotated position. Each shelf can also slide linearly along the set of slide assemblies to a deployed position.

  • Patent number: 10090070
    Abstract: Systems, methods, electronic devices and computer-readable media for charting dental information are described. The method includes generating or retrieving a dental data set including separately-modifiable parameters defining dental information relative to a base parametric model, the parameters providing information for generating signals for displaying a three-dimensional (3D) representation of at least a portion of a dentition represented by the dental data set; receiving an input via the 3D representation; and based on the received input, adjusting at least one of the parameters.
