An auto safety jumper module to prevent accidental short circuits or wrong connections between a jump start system and a motor vehicle battery when jump starting such motor vehicle. The module can be fully automatic and capable of detecting when a motor vehicle battery is connected to it. The module, which can be integrated into or an external add-on to a jump start system, does not need an external sensing wire(s) to detect when alligator clamps of the jump start system are connected to a vehicle battery post or to detect when the alligator clamps are disconnected.

A motorized bicycle includes a frame, a plurality of wheels coupled to the frame, pedals coupled to the frame for driving at least one of the wheels, gear(s) coupled to the frame, a motor coupled to the pedals and at least one of the wheels; a battery for supplying power to the motor; and a controller. In response to a selection of a current gear, the controller regulates a power output from the battery to the motor based on the current gear, where the motor propels the motorized bicycle to travel within a predetermined speed range associated with the current gear.

An electrical outlet includes an outlet housing having an outer support arm and an inner support arm, the outer and inner support arms defining a socket receptacle; the inner and outer support arms having a rotational support member and a fixed electrical contact assembly; a rotary socket having at least one plug receiver for receiving an electrical plug and a rotary contact plate attached thereto; wherein the rotary contact plate is rotationally supported by the rotational support member, and the rotary contact plate maintains electrical contact with the fixed electrical contact assembly through a predetermined range of rotation of the rotary socket. Rotation control functions of the rotary contact plate to limit the range of rotation and provide adjustable angles of rotation are also described.

A motorized bicycle includes: a frame; a plurality of wheels coupled to the frame; pedals coupled to the frame for driving at least one of the wheels; a motor coupled to the pedals and at least one of the wheels; a battery for supplying power to the motor; and a controller. When the controller determines that the motorized bicycle is traveling on a flat terrain or a decline, it enters or maintains a regeneration mode, where electric power is generated when a rider of the motorized bicycle pedals, and the electric power is used to charge the battery. When the controller determines that the motorized bicycle is traveling on an incline, it enters or maintains an assistance mode, where any regeneration of the battery is stopped, and power output from the motor is used to assist the rider in propelling the motorized bicycle forward.

A high efficiency battery charger. The high-efficiency battery charger can include a first transformer to produce a charging current, a second transformer to produce a maintenance current lower than the charging current, a power feed circuit having an input for connection to a power source, and control circuitry configured to detect a depleted battery to cause the power feed circuitry to feed power to the first transformer while disabling the second transformer, and to detect a charged battery to cause the power feed circuitry to feed power to the second transformer while disabling the first transformer.

A controller for controlling a voltage applied to a load from a power source includes a square wave producing circuit for connection in the circuit with the battery and the lamp. The square wave producing circuit produces a variable duty cycle square wave for controlling application of power to the load in accordance with the duty cycle of the square wave. The square wave producing circuit has a control input for varying the duty cycle of the square wave in response to a voltage at the control input. A voltage varying circuit is connected to the power source for producing a selectively variable voltage that is fed to the control input of the square wave producing circuit for selectively adjusting the duty cycle of the square wave. A low voltage detection circuit is connected to the power source and coupled to the control input of the square wave producing circuit for automatically producing a voltage that decreases the duty cycle of the square wave when the battery voltage decreases to or below a selected level. The selected level may be set according to a value of at least one impedance within the low voltage detection circuit.
