An intelligent video / audio observation and identification database system may define a security zone or group of zones. The system may identify vehicles and individuals entering or exiting the zone through image recognition of the vehicle or individual as compared to prerecorded information stored in a database. The system may alert security personnel as to warrants or other information discovered pertaining to the recognized vehicle or individual resulting from a database search. The system may compare images of a suspect vehicle, such as an undercarriage image, to standard vehicle images stored in the database and alert security personnel as to potential vehicle overloading or foreign objects detected, such as potential bombs. The system may track individuals or vehicles within a zone or between zones. The system may further learn the standard times and locations of vehicles or individuals tracked by the system and alert security personnel upon deviation from standard activity.

A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack. The device includes an input receptacle for receiving a stack of bills to be evaluated and a single output receptacle for receiving the bills after they have been evaluated. A transport mechanism transports the bills, one at a time, from the input receptacle to the output receptacle along a transport path. The device further includes a discriminating unit that evaluates the bills. The discriminating unit comprises two detectors positioned along the transport path between the input receptacle and the output receptacle. The detectors are disposed on opposite sides of the transport path so that they are disposed adjacent to opposite sides of the bills. The discriminating unit counts and determines the denomination of the bills. The evaluation device also includes means for flagging a bill when the denomination of the bill is not determined by the discriminating unit.

The invention consists of a uniquely punched or printed key, often in the form of a card, that is used to identify and authenticate a user during online transactions. The computer randomly generates an array of characters, such as numbers, letters or symbols, which is displayed to the user, e.g., on a computer monitor, or printed, such as in matrix format. When held over the displayed matrix, the key allows the user to view only certain portions of the matrix, which portions together form the user's one-time-password, which is unique for each authentication transaction. The user is then authenticated by utilizing both the actual key and a password or personal identification number. This two-pronged requirement for authentication insures the high security level provided by the system.

An adjustable golf putter comprising a top shaft assembly, a bottom shaft assembly, a hosel assembly, a putter head, and a removable handle assembly. When the handle assembly is installed, the ergonometric golf putter has a zigzag shape. This configuration better enables the golfer to sight the ball and effect a putt. When the handle assembly is removed, the ergonometric golf putter has a straight shape. This configuration enables the golfer to utilize the golf putter as a traditional straight golf putter. In addition, the hosel assembly defines a predetermined lie angle to accommodate the golfer's preference. The same putter is usually adaptable for a right or left handed user.

A vertical takeoff and landing aircraft, using for vertical lift and lateral thrust a redundant plurality of essentially similar electrically-powered and electronically-controlled thrust units mounted in a mechanically static or fixed fashion relative to one another in a substantially horizontal plane. The thrust units are situated in this planar array in aerodynamically approximate pairs, such that a complete failure of a single thrust unit would not substantially compromise the ability of the aircraft to maintain flight.

Externally detectable electronic article surveillance markers are attached to surgical implements, such as sponges and surgical instruments, appointed for use in a surgical wound. The attachment mechanism facilitates detection by an external interrogating field before the wound has been closed and the patient has left the operating table. The markers are responsive to the imposition of an interrogating field produced by an electronic article surveillance system. Markers contain one or more magnetomechanically responsive elements that are urged into mechanical resonance by the interrogating field. The ring-down of the resonance and the associated dipolar electromagnetic field provide a signal-identifying characteristic detected by a detection system. Upon detection, an audible or visible signal is triggered to alert relevant medical personnel to the need for follow-up care and removal of the offending item. The resonance occurs at a frequency ranging from about 70 to 300 kHz. Misadventures during operative procedures—especially those wherein implements remain undiscovered at the time of surgery and are retained indefinitely within the surgical cavity, often entailing dire consequences to the patient—are virtually eliminated. The attachment mechanism and markers assure that surgical implements are reliably detected and removed before completion of the surgical procedure.

A drive hub configured to mount to the spokes of an off-the-shelf spoked wheel on a vehicle such as, for example, a bicycle, so as to allow said wheel to be driven by a motor mounted to the frame of the vehicle. The hub has an outer face including a channel or belt track for engaging a drive belt from the motor, and the inner side of the hub has formed therein spoke slots configured to accept and lock upon spokes situated on the front or rear wheel of the bicycle, and are situated such that the hub is self-centering upon installation, namely, when all of the slots are lined up to engage spokes on the bicycle, the hub is appropriately centered on said wheel. Each spoke slot is of a width so as to accept an individual spoke, with there being provided ridges, notches or the like in each slot for engaging and locking about the spoke to resist removal of the hub from the wheel, once mounted thereupon. The hub is driven by a small motor (electric or gasoline) mounted to the frame of the unit, via, for example, a friction belt drive system.

The instant invention is a power-generating device, comprising a shaft assembly having an elongated shaft that is mounted onto a vehicle. The elongated shaft comprises shock-absorbing means. A wheel assembly is mounted onto the shaft assembly. The wheel assembly comprises at least one wheel and an electrical generator. The wheel rotates upon a surface on which the vehicle is traveling upon to generate power at the electrical generator or alternator for an engine of the vehicle. The electrical generator generates the power to a source of rechargeable battery power of the engine.

An electrical delay detonator for use in blasting initiation systems energized by a non-electric impulse signal transmitted through a non-electrical conduit, such as a shock tube, with one end inserted inside a detonator housing having redundant sensors for detecting the presence of a non-electric impulse signal and a computerized control circuit for actuating the firing circuit. An elevated voltage is generated, stored in a capacitor assembly, and discharged when fired to an electrically operable igniter. The igniter, when activated, detonates an explosive mass. A battery is also contained within the detonator housing for powering the control circuit and one sensor, in low consumption mode, for several days. Upon detecting the presence of a signal the rest of the circuits are powered up. Periodic time windows generated by the control assembly provide corresponding enabled time periods for the sensors to become operational.
