Problems solved by technology

However, it is not always practical or possible to incorporate a conventional switch such as a toggle switch or a push-button switch.
However, and particularly during shipping, such switches may be inadvertently activated causing the batteries to run down and thus reduce the life of the products.

Embodiment Construction

[0010] A motion or acceleration sensing switch may be selected from a wide family of switches such as mercury switches, spring switches, pendulum switches etc. A typical spring switch comprises two contacts one of which is a spring. Sufficient motion or acceleration causes the spring to deflect and thus close an electrical circuit with the other contact. The contact may be internal or external to the spring. The aforementioned broad family of switches is well known and the invention may employ any type of motion sensing switch to advantage. Thus, the term “motion sensing switch” or trigger is deemed to incorporate this broad family as well as its equivalents. It will also be appreciated that in place of motion sensors, the invention's teachings regarding “Sleep Mode” and “Active Mode” may be beneficial when other types of sensors such as sound or light sensors are used in place of or with motion sensors.

[0011] As shown in FIG. 1, a flashing light driver assembly 10 comprises and in...

Abstract

A shoe, soap or other article incorporates an integrated circuit having a first and a second input gate, and one or more outputs that can serve to supply power to a like number of light sources, like LEDs. The first input gate is responsive to a motion signal and acts to cause the integrated circuit to deliver a pattern of power signals to the one or more outputs. The second input gate is responsive to a second motion signal, the second motion signal actually being two or more motion signals occurring at a pre-determined frequency that the integrated circuit detects. The second input gate logically acts to cause the integrated circuit to alternate between a sleep mode and an active mode. The first input gate is disabled by the integrated circuit when the integrated circuit is in sleep mode.

Description

FIELDS OF THE INVENTION [0001] The invention pertains to flashing light drivers and more particularly to a driver for one or more LED's. BACKGROUND OF THE INVENTION [0002] Low cost, reliable LED's are commonly used as sources of illumination in objects such as fishing lures, soaps, shoes and other practical and novelty items. In order to keep the above referenced units inexpensive and lightweight, small batteries are used. For this reason, it is desirable to extend the shelf life and the useful life of such products by switching the LED's off when they are not in use. However, it is not always practical or possible to incorporate a conventional switch such as a toggle switch or a push-button switch. Prior art devices have utilised motion sensing or acceleration sensing switches such as mercury switches, spring and post switches, post and ring switches, accelerometers and the like. However, and particularly during shipping, such switches may be inadvertently activated causing the bat...
