Abstract: A boat having a helical drive mechanism. The helical drive mechanism includes a slider engaged with a twisted screw or a cylinder having a helical slot or groove. The helical drive mechanism is connected to a force input shaft which is arranged within the boat so that it can be driven by the user's feet or hands. The user drives the force input shaft in a rectilinear motion to force the twisted screw or cylinder of the helical drive mechanism to rotate. This force is ultimately transferred to a propeller to move the boat.

The horse is secured to the lanyard by the animal halter attachment member and the lanyard is secured to a stationary object by the stationary object coupling member to secure the horse to a stationary object to prevent the horse from leaving.

Abstract: A display and method for holding printed material, such as advertising, are described for hanging on the back of a vehicle seat with its contents easily visible and accessible to a passenger. A transparent backboard having rear and front surfaces define transparent pockets for holding the advertising. A pair of hook and loop straps and pads secure the display to the back of the seat.

Abstract: An improved semiconductor device is disclosed for protecting active and passive devices against electrostatic discharge (ESD). The device is an improved semiconductor diode having anode, injector and ohmic contact regions located within a cathode region. The improved semiconductor diode allows for ESD higher currents without damage to active or passive devices including, for example, resistor-capacitor networks or resistor-capacitor-inductor networks incorporating the improved semiconductor diode.

Abstract: A shoulder protection device for use with a barbell, during the performance of a bench-press-type exercise. The device consists of a cylindrical pad adapted to be coupled to the barbell at a point substantially over the chest of a user, and having sufficient thickness to reduce the downward travel of the barbell during the performance of a bench-press movement. Such reduction, preferably, should be to the point where the upper arms descend to the horizontal plane defined by the back of the user, but do not break that plane.

Abstract: A property maintenance scheduling system has a calendar for displaying a current month. The calendar has an area for listing property maintenance to be performed during the month. The maintenance system further has two pluralities of labels. The first labels are to be placed on the calendar to indicate the date that specific maintenance is due to be performed. The second labels are to be placed on each item to record the date on which an item will next be serviced. The calendar may also be electronic in nature. A notebook may further be provided in the property maintenance scheduling system. The notebook is used for detailing the procedure for each property maintenance task to be performed during the month. The notebook may further be used for recording details of the work performed for each property maintenance task.

Abstract: A wheelchair is provided with a helical drive mechanism. A rectilinear input to the helical drive causes an output gear to rotate, thus providing power to rotate the driving wheels of a wheelchair. The helical drive may include, for example, a compound helix, a drive with a twisted flat bar, or a concentric helix drive. Add-on components may be provided to convert a conventional wheelchair to a wheelchair powered by a helical drive mechanism.

Abstract: A device and method is disclosed for rubbing away by abrasion, selected skin areas of a person's foot or feet in a shower or bath area. An elongated base portion of the device has on a bottom side thereof a plurality of suction cups attached to the bottom side to provide a secure grip to a shower or bath tub floor. The top side of the elongated base portion has an abrasive material attached thereto which functions to permit abrading away of selected skin portions of a person's foot. This abrasive material is also located on two elevated side wall portions that are attached (one to a side) to both sides of the device to permit side portions of a person's foot to receive the abrading operation.

Abstract: An improved RC network integrated circuit semiconductor device is disclosed which incorporates an improved method for fabrication. The new device and method includes the use of a tantalum nitride layer as the resistive material for the resistor and a protective metal layer formed between the resistive layer and a metal interconnect layer. The capacitor uses a metal electrode as one plate of the capacitor and a heavily doped semiconductor region as the other plate of the capacitor and separated from the one plate of the capacitor by a silicon nitride insulation layer.

Abstract: A shower douching system is shown. The shower douching system comprises; a solution reservoir, a shower passageway coupled to the solution reservoir, and a controllable shower douche coupled to the shower passageway and coupled to the solution reservoir for controlling a shower fluid flow diversion. The controllable shower douche comprises a valve coupled to a shower bypass channel for controlling the shower fluid flow diversion, and further comprises an eductor connected downstream of the shower bypass channel for creating a low pressure condition within the eductor. The eductor is coupled to a solution suction channel extending substantially within the solution reservoir, and a douche fluid outlet channel is coupled to the valve.

Abstract: A blackjack table card game and method is disclosed which permits each player betting against a dealer several betting options by placing one or more chips in one or more separate betting regions located in front of each player. One of these betting regions permits a player to bet that the player will receive a two-card blackjack consisting of one card having a value of nine, ten, eleven or twelve and the other card having a corresponding respective value of twelve, eleven, ten or nine in any two card sequence. Preferably 60 playing cards are used consisting of a standard deck of 52 playing cards and eight additional playing cards which consist of four different suited playing cards each having a value of 11 and four different playing cards each having a value of 12.

Abstract: A bicycle with a drive mechanism using reciprocal rectilinear pedal motion to propel a pinion gear against a crown gear face associated with a rear bicycle wheel, rotating the rear wheel. The pinion gear receives motion from a helical member surrounded by a slider. Each pedal is united with the slider which moves linearly along a guide or track, forcing rotation of the helical member as the slider is pushed rearwardly by a pedal. A freewheel or overrunning clutch permits power transfer only when the pedal moves rearwardly and allows freewheeling when the pedal is reset. Reciprocal, linear pedal strokes power the bicycle.

Abstract: A magnetically latching butterfly knife 10 having a magnetic latch 20 coupled thereto. The magnetic latch 20 is coupled to the magnetically latching butterfly knife 10. The magnetic latch 20 is coupled to at least one of the handle components 14 and/or 15. The magnetic latch 20 has at least one magnetic component 19 and at least one magnetic attracting surface 10A (i.e. magnet or metal surface) that are able to couple to at least one of the handle components 14 and 15. At least one magnetic component 19 and at least one magnetic attracting surface 10A magnetically attract and couple to each other to be able to provide open and closed latching operations for the butterfly knife 10. The magnetic latch 20 secures the first handle component 14 and the second handle component 15 in an open latched position and also in a closed latched position. The magnetic latch 20 may be configured and coupled to the butterfly knife 10 in many ways in order to provide the open latched and closed latched positions.
