  • Patent number: 10713906
    Abstract: A portable electronic device used for monitoring and alerting about the presence of an object includes an enclosure having a portability mechanism and an electronic circuit having a motion detection sensor, a bipolar junction transistor, an alert generator, a Bluetooth® module and a power source coupled to the motion detection sensor, the bipolar junction transistor, the alert generator and the Bluetooth® module. The motion detection sensor is configured to detect movement of the object across an area in front of the sensor and generate a timed output signal. The bipolar junction transistor is communicatively coupled to the motion detection sensor and configured to activate a control signal in response to the timed output signal. The alert generator and the Bluetooth® module are communicatively coupled to the bipolar junction transistor and configured to produce an alert and a Bluetooth® signal respectively in response to the control signal.

  • Patent number: 7461864
    Abstract: A recreational motor vehicle capable of accommodating a driver of varying sizes. Embodiments can also be modified for use on circular or in-line tracks or multiple racing formats. The external appearance of the vehicle may be readily modified through the switching of a exterior body which is supported on a rigid frame that completely encloses and protects the driver. Further safety features may be provided such as; a firewall between the engine and seat, fire suppression system, and escape hatch.

  • Patent number: 6772675
    Abstract: Frozen beverage mixing unit has a hollow housing with an open bottom. A shaving disc with a cutting knife is rotationally mounted inside the housing, the shaving disc being connected to a motor. A piston moves above the shaving disc pushing a frozen product into a contact with the cutting blades of the shaving disc. A plurality of pumps deliver a pre-determined amount of a selected additive, such as alcohol, syrup, carbonated water or water, on top of the shaving disc to mix with the ice crystals created by the shaved frozen product. The additive is mixed with the shaved frozen product in a mixing container placed below the shaving disc.

  • Publication number: 20020194999
    Abstract: Frozen beverage mixing unit has a hollow housing with an open bottom. A shaving disc with a cutting knife is rotationally mounted inside the housing, the shaving disc being connected to a motor. A piston moves above the shaving disc pushing a frozen product placed on the shaving disc, into a contact with the cutting knife. A water pump delivers a predetermined amount of water on top of the shaving disc to wash away remnants of the shaved off product. The water is mixed with the shaved frozen product in a mixing container placed below the open bottom. A flavoring liquid, be it an alcoholic beverage or a non-alcoholic syrup, is delivered into the mixing container in a location below the shaving disc.

  • Patent number: 5129702
    Abstract: The fold-away table is attached to an underside of a chair, sofa or the like. The fold-away table provides for the use of two parallel rails which are attached to the underside of the chair, along which rails a carriage slides forward and rearward in relation to the chair. One of the rails carries a locking bar with teeth formed on its inner side which match and interlock with teeth of a locking piece carried by the carriage, so as to secure position of the carriage in relation to the chair when extended. The carriage has a table top leg support which pivots to a vertical orientation and which has a table top supported on one of its tubular members. A tilting mechanism carried by the tubular member allows tilting of the table top to an angle most convenient for the user. A release mechanism which is mounted on the forward end of one of the rails is activated by foot of the user, when necessary, to release locking engagement of the locking bar and the locking piece.
