Abstract: An apparatus which is used to cover a tire in order to prevent the tire from leaving marks on an area the tire travels across. The apparatus uses an elongated flexible piece of material of sufficient length to cover the outside circumference of the tire. The piece of material is used to cover the outside circumference of the tire to prevent the tire from leaving marks on an area the tire travels across. A connector is used for connecting a first end of the piece of material to a second end of the piece of material thereby securely coupling the piece of material to the outer circumference of the tire.

Abstract: An improved semiconductor device which includes a zener diode and RC network combination that share common semiconductor mask steps during the fabrication process. A common N+ layer serves to provide both the separate N+ cathode regions of the zener diode and the separate bottom electrode N+ region of the capacitor. A common metal layer serves to provide separate electrical contacts to the N+ cathode regions of the zener diode and also provides a separate top metal electrode for the capacitor. The capacitor dielectric is comprised of silicon nitride. A silicon dioxide/silicon nitride insulation layer is formed between the top metal electrode of the capacitor and a resistive layer typically made from tantalum nitride.

Abstract: A human habitat structure for placement upon a non-uniform, non-level site.

Abstract: A stabilized wafer for monitoring and calibrating oxide charge test equipment. The stabilized wafer comprises; a silicon wafer, a SiO2 layer of at least 100 angstroms upon the silicon wafer, and a phosphosilicate glass layer containing phosphorus formed in the SiO2 layer for providing the stabilized wafer by stabilizing an SiO2 interface and containing oxygen ions. The stabilized wafer is used for monitoring and calibrating oxide charge test equipment.

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.

Abstract: A horse securing device and method therefor, comprising a lanyard, an animal halter attachment member, a stationary object coupling member, a weight, and an adjustment member allowing the adjustment of the length of the lanyard. 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: 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: An aircraft navigational system allows for reduced storage and increased computing power for comparing terrain maps to the flight path and enroute track of the aircraft. Unique provisions are made for reporting and recording navigational hazards.

Abstract: A locking apparatus for providing security for either unauthorized access or unauthorized removal of portable computers. The portable computer sets on a base tray that has side and rear walls with access ports. A combined assembly of a removable locking member and an adjustable security member fits snugly over the top surface of the computer. The combined assembly is secured to the rear wall of the base tray by a flange and to the front of the base tray by a locking 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: 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: 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 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.
