  • Publication number: 20240096165
    Abstract: A brushless motor system for use with a mechanical reel gaming machine is provided. The brushless motor system includes a reel hub and a reel frame rotationally attached to a center shaft of the reel hub. The brushless motor system also includes a permanent magnet (PM) rotor attached to the reel frame and including a plurality of permanent magnets attached to the PM rotor. The brushless motor system further includes a stator including stator coils attached to the reel hub, the plurality of stator coils are mounted parallel to a surface of the PM rotor at a separation distance. The stator causes the PM rotor to rotate during activation of the stator without direct contact between the stator and the rotor, thereby causing the display of one or more symbols of the plurality of symbols during the wagering game based on the rotation.

  • Patent number: 10332828
    Abstract: Some embodiments relate to a semiconductor power device that includes a first substrate, a second substrate, a stack and an interconnect structure. The first substrate includes a first patterned electrically conductive layer on a first surface and a switching semiconductor element. The second substrate includes a second surface facing the first surface and a second patterned electrically conductive layer on the second surface. The stack includes an electrically conductive track and a layer of a dielectric material. The layer of the dielectric material is provided on the first or second patterned electrically conductive layer and the layer of the dielectric material isolates the electrically conductive track from the patterned electrically conductive layer on which the stack is provided. The interconnect structure provides at least one electrical connection electrically conductive layers or areas of the substrates.

  • Publication number: 20110288891
    Abstract: An on-demand third party asset rental platform is provided. In some embodiments, on-demand third party asset rental platform includes a self-service platform that enables a third-party renter to electronically submit a conditional rental offer (CRO) for an asset to a plurality of third-party owners of that asset. In some embodiments, on-demand third party asset rental platform includes receiving a request for an asset (e.g., a vehicle or another type of asset) rental; and in response to the request for an asset rental, communicating a plurality of conditional rental offers to a plurality of asset owners, wherein each of the asset owners specifies the asset owner's rental terms. In some embodiments, an asynchronous protocol for CRO distribution is provided.

  • Patent number: 7173206
    Abstract: A switch assembly is provided which includes a holder defining at least a pair of eyelets extending completely therethrough; an electrically conductive lead-frame supported on the holder, the lead-frame defining at least a pair of openings therein; and at least a pair of electrically conductive rivets each configured and adapted for at least partial positioning in a respective eyelet. The first opening of the lead-frame is larger than a head portion of a first rivet such that the head portion does not contact the lead-frame. The second opening of the lead-frame is smaller than a head portion of another rivet such that the head portion contacts the lead-frame. The switch assembly further includes at least one electrically conductive snap dome in electrical contact with the lead-frame and overlying the first rivet.

  • Publication number: 20060211662
    Abstract: A topical drug composition for the treatment of age-related maculopathy, age-rlated macular degeneration, ocular hypertension, glaucoma or other eye disease resulting from increased intraocular pressure comprising a solution of anabolic androgenic agent and 17-?-estradiol suspended or dissolved in a suitable ophthalmic vehicle is disclosed. In the preferred embodiment, 17-?-estradiol, or its esters, is in a lipid vehicle or 17-?-estradiol-3-phosphate, or other esters of 17-?-estradiol, is combined with an anabolic androgenic agent in an aqueous vehicle having a pH of between about pH 6 to pH 8. The composition is administered to the eye in an effective amount to maintain physiologic or normal intraocular pressure or to return elevated intraocular pressure to lower levels.

  • Patent number: 6883949
    Abstract: A light pipe having one or more exterior protrusions that function as a secondary light source and an alignment component. The one or more exterior protrusions may provide a secondary light source by reflecting light from a primary light source. The one or more exterior protrusions also may function to align the light pipe with a lamp assembly or an object on which the light pipe is mounted. Further, a lamp assembly having a light pipe receiving portion, with one or more slits to allow an opening to expand upon insertion of the light pipe, and to provide a retention force upon contraction.
