  • Publication number: 20230299550
    Abstract: The system includes an optical resonator, a mount, and a fastener. The optical resonator is comprised of a material with a horizontal plane symmetry. The optical resonator includes a horizontal plane protrusion for mounting. The horizontal plane protrusion includes discrete resonator rotational orientation positions. The mount comprises mounting legs compatible with the horizontal plane symmetry. The mount includes discrete mount rotational orientation positions that correspond to the discrete resonator rotation orientation positions at a plurality of rotational angles. The fastener secures the horizontal plane protrusion of the optical resonator to the mount.

  • Patent number: 11056354
    Abstract: Described is a semiconductor substrate stack, including: a plurality of semiconductor substrates arranged in a stack in which the semiconductor substrates include opposing facing surfaces, wherein the facing surfaces of adjacent semiconductor substrates are separated by a gap, each semiconductor substrate having an edge surface at an exposed edge of the stack. A spacer is attached to one of the facing surfaces of each of the at least one of the semiconductor substrates and extends between adjacent semiconductor substrates to define the gap and mask a central portion of each respective semiconductor substrate.

  • Patent number: 9104780
    Abstract: According to embodiments described in the specification, systems and methods are provided for natural language processing. A method in a server includes receiving, at the network interface device, an input for response from an electronic device, parsing the input to identify one or more entity data values and one or more relationship data values, populating a graph data structure with the identified entity data values, and the relationship data values, wherein the populating includes applying evaluation criteria-rating pair values, traversing the graph data structure to identify one or more problems indicated by the evaluation criteria-rating pair values, in response to the traversing, determining one or more changes to the graph data structure to satisfy one or more identified problems, if the determination is affirmative, populating a solution graph data structure that satisfies one or more identified problems, and transmitting, to the electronic device, a response to the input.

  • Publication number: 20140280210
    Abstract: Systems and methods are provided for natural language processing. A method in a server includes storing a graph data structure (GDS) of nodes, each node associated with an entity data value, and links, wherein each link connects two nodes and is associated with a relationship data value and evaluation criteria-rating pair values, receiving an input for response from an electronic device, parsing the input to identify entity data values and relationship data values, populating the GDS with the identified entity data values, and the relationship data values, wherein the populating includes applying evaluation criteria-rating pair values, traversing the GDS to identify problems indicated by the evaluation criteria-rating pair values, in response to the traversing, determining changes to the GDS to satisfy identified problems, if the determination is affirmative, populating a solution GDS that satisfies identified problems, and transmitting, to the electronic device, a response to the input.

  • Publication number: 20110130768
    Abstract: An identification tag loading means (1) includes a chamber (5, 7) in which the head portion (12) and cutting tip (13) of a one piece animal tag (8) can be accommodated. At this time the aperture (11) at the outer end of the hollow shank (10) is exposed and ready for loading the tag (8) onto the applicator pin (14) of an ear tag applicator (15). This reduces the risk of damage to a users hands by contact with the tip (13).

  • Patent number: 4693613
    Abstract: A clock having an hour housing supporting an integral hour hand and a minute housing supporting an integral minute hand along with a timing mechanism supported within the hour housing and having hour and minute driven shafts coupling to the respective hour and minute housings. There is provided a logo disk at the front of the clock which is maintained in a stationery position relative to the adjacent rotating minute housing. A support bracket is used for supporting the timing mechanism from a wall or the like.

  • Patent number: 4674891
    Abstract: A clock having an hour housing supporting an hour hand integral therewith in a minute housing supporting a minute hand integral therewith. A battery operated timing mechanism in the hour housing has an hour shaft for driving the hour housing in hand and a minute shaft for driving the minute housing in hand. The coupling of the minute shaft includes a threaded shaft end having opposed flats adapted to force-fit in a centrally disposed hole on the inside of the minute housing. A bracket is provided for supporting the timing mechanism in a fixed position such as from a wall.
