Definitions
- This invention relates generally to a system for locating luggage or other missing items. More particularly, the invention relates to an apparatus and method for identifying the location of a missing piece of luggage including a transmitter and receiver which employ electronic circuitry.
- This invention was conceived to solve a common problem experienced by travelers, namely, to have some means for identifying or locating their luggage in a baggage claim area of an airport, bus terminal or the like. Luggage is often confused with similar looking luggage or mistakenly removed from the baggage claim area and moved to another location. It is therefore typical in airports for travelers to have difficulty identifying or finding their luggage.
- U.S. Patent 5,126,719 to DeSorbo discloses a remotely armed suitcase alarm system. The system comprises a remote transmitter unit and a motion sensitive alarm which is attached to the suitcase and includes a signal receiver unit.
- U.S. Patent 5,043,702 to Kuo discloses an alarm/security device integrated in the luggage which can be remotely activated to produce a siren and an electric shock.
- U.S. Patent 5,576,692 to Tompkins discloses an airport luggage tracking system which utilizes a beeper paging device and requires a telephone call through a nationwide paging system to locate the luggage.
- the prior art devices attempt to solve the same general problem of locating luggage by a signal -activated receiver or an alarm transmitter attached to the luggage.
- each has a problem in utilization which makes it relatively unattractive to manufacture or use.
- Some devices incorporate costly timer shutoff or battery power saver circuitry in an attempt to conserve power usage and prolong the use time between battery changes.
- To attract the user's attention others require a loud alarm or distinctly audible type of sound, such as a loud continuous beeping, which may be annoying or disturbing to other people in the vicinity.
- Other devices employ complex triangulation locator circuitry in order to allow a person distant from the object to home in on the object.
- Still others employ cumbersome encoding circuitry and activation elements to initialize individual devices for a plurality of objects that might be lost.
- inexpensive timer shutoff or battery power saver circuitry, loud annoying sounds, triangulation locator circuitry, or cumbersome encoding elements are avoided.
- an object locator system comprises: a transmitter unit having a casing housing a transmitter circuit therein for outputting an RF signal, and a pushbutton operable externally of the casing and coupled to the transmitter circuit for sending the RF signal only when the pushbutton is pressed; and a receiver unit having a casing provided with attachment means for allowing it to be attached to or incorporated into an object, said casing housing a receiver circuit for receiving the RF signal transmitted by the transmitter unit and outputting an activation signal, and a light illumination element that is illuminated in response to the activation signal, wherein said receiver circuit is operative to output said activation signal only for so long as the RF signal is received from the transmitter unit.
- the light illumination element is a light pipe mounted on the receiver casing and having a length running at least partially around a perimeter of the receiver casing.
- the casing is formed in two complementary halves, and the light pipe is retained in a recess in the walls of the casing halves.
- two light pipes may be employed on opposing sides of the receiver unit.
- the transmitter circuit includes a digital oscillator and a means for setting the transmitter circuit to send a unique coded signal
- the receiver circuit includes a digital decoder circuit and a means for setting the receiver circuit to detect the unique coded signal, whereby the receiver unit only responds to the transmitter unit sending the unique coded signal .
- the unique coded signal may be set in the transmitter and receiver circuits either by the user by means of a dip switch array, or the signal may be preset or electronically coded during manufacture, which enables a broader range of coded signals.
- the receiver casing may be formed with an through- hole at a narrowed end, through which a fastener is inserted for attaching the receiver unit to a selected object.
- the light illumination element and attachment means may be combined in one element or the receiver casing may be incorporated directly into the selected object.
- the transmitter unit is formed as a small hand held unit about the size of a key ring.
- the receiver unit includes a sound generator for generating a sound output in response to the activation signal in cases where the object is out of the user's visual field or hidden from view.
- the invention also encompasses the related method of sending the RF signal and illuminating the light element only for so long as the RF signal is received from the transmitter unit, in order to provide the user direct visual feedback to the user's pushbutton presses that would make it easy to locate the object in a crowded visual field.
