  • Patent number: 11059178
    Abstract: A position correction method includes: a step of opposing a hand to a target by moving the hand such that the hand becomes in a predetermined first initial posture; a first position detection step of detecting a position of the target from a rotation angle of a rotation axis when the target blocks a detection light by swinging the hand; a step of opposing the hand to the target by moving the hand such that the hand becomes a predetermined second initial posture different from the first initial posture; a second position detection step of detecting a position of the target from the rotation angle of the rotation axis when the target blocks the detection light by swinging the hand; and a correction amount arithmetic step of obtaining rotation angle correction amounts of the second axis and the third axis based on a difference between the position of the target acquired in the first initial posture and the position of the target acquired in the second initial posture.

  • Publication number: 20200385996
    Abstract: The present invention relates to a cassette framing system consisting of at least one hinge assembly and cassette, with a cassette frame, which allows for loading the top of a cassette frame onto a structural mullion located within a cassette framing system. The hinge assembly permits the installer to stabilize and align the cassette and cassette frame during the installation of the cassette frame onto the cassette framing system. The cassette framing system permits the use of a plurality of different types of infill materials within the cassette. The use of a hinge assembly permits ease of field installation while employing narrow joint profiles which have aesthetic benefits.

  • Patent number: 10693832
    Abstract: A network where FC and Ethernet storage traffic share the network. The network extends FC SAN storage attributes to Ethernet storage devices. The network is preferably formed of FC switches, so each edge switch acts as an FCoE FCF, with internal communications done using FC. IP packets are encapsulated in FC packets for transport. Preferably, either each outward facing switch port can be configured as an Ethernet or FC port, so devices can be connected as desired. Ethernet addresses of IP devices are discovered based on ARP requests and lookup misses. Once an ARP request is trapped, the source device's information is added to a local database and distributed within the network. If the destination device is not known, a network-specific fabric protocol is used to propagate the ARP request to the other switches. An ARP response is processed similarly to update the local database and to distribute the update.

  • Patent number: 10448823
    Abstract: A test of visual function and/or functional vision may be performed at varying luminance levels. A first course may be selected for a subject. A given course may comprise a layout having a beginning point, at least one turn, at least one obstacle, and an ending point. The first course may be illuminated with a first luminance level based on an estimated lower light sensitivity cutoff. The subject may be prompted to perform a first run of the test. The test may comprise, from the beginning point to the ending point, navigating the layout of the first course by walking around the at least one turn and avoiding the at least one obstacle. A determination may be made as to whether the subject successfully completed the first course based on one or both of speed or accuracy.

  • Patent number: 9860196
    Abstract: In a Fiber Channel SAN and its included routers, each router contains only the LSAN zones that contain devices attached to edge fabrics which are connected to the router. LSAN zone entries include the fabric ID (FID) of each device in addition to the WWN. When a router obtains a new zone database for a newly connected or changed fabric, the router scans the LSAN zone entries for fabric IDs matching a fabric connected to the router and stores those entries. All other LSAN zone entries are not stored. In this manner the size of the relevant tables are reduced, which allows for greater expansion of the SAN as a whole.

  • Patent number: 9654422
    Abstract: Is in a Fibre Channel storage area network (SAN) and its included routers, the routers are placed in groups or pods. Each router only contains router port and fabric access data for routers in the same group or pod. In this manner the size of the relevant tables are reduced, which allows for greater expansion of the SAN as a whole. Each router may be programmed by an administrator with a pod value, indicating the pod containing the router. This value may be provided to the Name Server during router registration and may be requested from the Name Server when developing the router's inter-fabric router (IFR) topology or the pod value can be exchanged in the IF_ILS_HLO messages. Router port database information is only stored from routers in the same pod or provided to routers in the same pod, thus reducing the entries in the router port database.

  • Publication number: 20170114242
    Abstract: The present disclosure relates to a passivation layer comprising a photocrosslinked fluoropolymer and a process for forming the layer. Passivation layers comprising the crosslinked fluoropolymer have low dielectric constants, low water absorptivity and are able to be photoimaged so as to provide the very fine features needed for modern electronic equipment.

  • Patent number: 9397958
    Abstract: An FCoE VN_Port virtualizer where VF_Ports are used to connect downstream to host and target VN_Ports and a VN_Port is used to connect upstream to further FCoE VN_Port virtualizers or to an FCF. An alternate embodiment uses an Ethernet Fabric for an additional purpose. The Ethernet Fabric devices all act as FCoE VN_Port virtualizers, so that the Ethernet Fabric itself is considered a virtual FCoE VN_Port virtualizer.

  • Publication number: 20150296553
    Abstract: Systems, devices, and methods establish proximity-based wireless connections. A first electronic device and a second electronic device are each operated in respective “connection establishment modes” in which the first electronic device wirelessly transmits wireless signals and the second electronic device wirelessly receives at least one of the signals and determines an indication of a distance between the two devices based on a property of the received signal(s). If the distance is found to be below a threshold, a wireless connection is established between the two devices. In this way, a user may selectively pair a portable electronic device with a particular one of any number of available electronic devices by momentarily placing the portable electronic device in close proximity to the particular electronic device with which a wireless connection is desired.
