Abstract: A drinking vessel including a beverage container and a closure assembly attachable to the beverage container. The beverage container has a spout defining a first drinking opening and a second drinking opening. The closure assembly includes a positioning member and a sealing member. When the positioning member is in a sealing orientation, the positioning member can extend deep enough into the first drinking opening for the sealing member to seal the first drinking opening and the second drinking opening. When the positioning member is not in the sealing orientation, the positioning member cannot extend deep enough into the first drinking opening for the sealing member to seal the first drinking opening and the second drinking opening.

Abstract: A lid may be sized and configured to be attached to a container and the lid may include a spout and a flip-top closure. The flip-top closure may be movable between open and closed positions relative to the spout. The lid may also include a carrying member with a loop-shaped configuration. The lid may further include one or more flanges and the flanges may include one or more protrusions. The protrusions may form a pivot point about which the flip-top closure pivots between the open and closed positions. The protrusions may also allow the carrying member to pivot independently of the flip-top closure.

Abstract: The disclosed invention is a solar tracker that is a simple 2 axis system that can be powered with integrated stepping motors and lead screw actuators that provides the necessary structural support and 2 degrees of freedom in the motion of the solar collector, to increase the electrical output of the system. Since the solution is designed for use with only one solar panel the mechanical forces such as wind load are much lower and easier to manage. The disclosed invention is also a solar tracker that is a single axis version where the base is fixed and the elevation is set at an average value for the location and pivoting mechanism operates the azimuth axis. Since the dominant energy improvement comes from tracking the azimuth, this would be a likely solution where a lower cost or less complex system is desired.

Abstract: An integrated gearbox/encoder and control system that includes: a gearbox with an output shaft connected to a mechanical load; a first sensor detecting the rotary position of the output shaft; a motor; a second sensor detecting the rotary position of the motor; and a system controller controlling motive drive to the motor. The two rotary position sensors permit direct determination of gearbox backlash which can be used in motor control. A drive current sensor similarly permits determination of a vibration signature for comparison with a standard.

Abstract: A method and apparatus for wheelchair control. The position and distance of a touch point on a touch pad is used to set speed and wheel differential control. The two major wheels of the wheelchair are controlled according to these set quantities. Exceeding either of two horizontal accelerations measured by an accelerometer limits the set speed. Wheelchair control is shut down upon exceeding a vertical acceleration limit.

Abstract: A linear actuator has four drive gears which engage two racks. The actuator movable member may comprise two racks which have gear teeth which face inwardly and towards each other, or a single rack which has gear teeth which faces outwardly. In either case, four gear drives to engage the rack, two gear drives on each side. A plurality of linear actuators may be used to provide for position control in two or more directions. Control is provided by a servo mechanism.

Abstract: A video game in which the player must fill mugs from a keg and slide the filled mugs down a bar to advancing thirsty patrons to repel the patron out the bar. The player controls movement of a host image from one horizontal bar to another and laterally along a bar plus the filling of mugs. If any of the thirsty patrons reach the keg end of the bar the player loses a turn. Repelled patrons are delayed while drinking and then return the empty mugs. Unless the empty mugs are caught by the host the player loses a turn. A turn is also lost if the player serves a full mug and there is no thirsty patron awaiting it. From time to time a tip will appear on one of the bars which the host image may pick up causing dancers to appear for an interlude during which some of the patrons turn to watch. While watching the patrons neither advance nor are thirsty. Bonus entertainment racks are periodically introduced during which six cans are displayed.

Abstract: A method and apparatus for a video game in which a player controllable video player image positions video dominos at predetermined positions along a continuous line while one or more machine controlled video intruder images attempt to interfere. Manual player controls move the player image to place the domino images and to protect against interference by the intruder images which could result in a chain reaction of falling dominos. The player manually selects either a place mode allowing the player image to place additional dominos or a protect mode for protecting itself or the dominos from an intruder. In an alternative embodiment, the player image also knocks over dominos while in the place mode. Duration of play is timed by a machine controlled image proceeding in a peripheral path to knock over the initial domino. Difficulty is increased by the complexity of the domino pattern, the timed duration, and the intruder images.

Abstract: A game includes the player's successive selection of matching images within a short time interval initiated by the first selection. Failure to select the proper matching image within the interval results in a mixing of the images. In an electronic video game version of the target shooting type a plurality of sets of matching targets are initially displayed. Each target has mating components. If the targets hit within the time interval do not match, components of each of the hit targets are exchanged to form a mixed target. The successively hit matched targets are removed but are replaced by another form of targets after the first rack. All of the prior form targets must be removed before the succeeding form can be removed from the screen. In still later racks, the initially displayed targets include ones with mixed components to increase the challenge. The player controls the movement of a shooter among the targets and directs the firing of projectiles at the targets.
