## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a system for remotely providing object location.
2. Background
Vehicle locators are well known. They may be used to locate a single vehicle. However, in daily life, we need an object locator to locate a variety of the target objects in a list. Moreover, all object locators are standing alone devices. Nowadays the existing device like cellular phone set, personal digital assistant, or car alarm remote is very commonly used. We may embed the object locator in the existing device to share its hardware, software, memory and display, etc., and becomes its additional application.
The target object to be located may not necessarily be a vehicle. It may be an equipment or machine moving around and stationary, perhaps carried by a person. To locate the equipment or machine means locating the person carrying it. Using a list to keep the identification of each equipment or machine shall help us to locate a person in the list one by one.
SUMMARY OF THE INVENTION
This invention provides an object locator to locate a variety of target objects. The object locator may choose a stored identification of the target object in an identification list to locate it. The object locator consists of a responding component residing in the target object and a hand held component A searching unit of the hand held component may send, to the responding component, an initial signal including the identification of the target object with a wireless wave through a selective directional transceiver and an omni-directional transceiver of the responding component. Receiving the initial signal, if the identification matches the identification stored in the responding component, the responding component shall send an acknowledge signal with the wireless wave through the omni-directional transceiver back to the selective directional transceiver of the hand held component. The responding component may cause a series of lights, like blinking lights, and sounds based on the strength of received wireless wave. And the display unit of the hand held component shall receive the acknowledge signal from the selective directional transceiver and display the strength of the acknowledge signal. The hand held component may also cause sounds and lights based on the strength of received wireless wave.
Horizontally angular turning the selective directional transceiver toward the target object at same horizontal level shall increase the strength of the acknowledge signal. Also vertically angular turning the selective directional transceiver toward the target object at different vertical level on a building shall increase the strength of the acknowledge signal. Moving the hand held component toward the target object shall decrease the distance between the hand held component and the target object, and increase the strength of the acknowledge signal. Therefore horizontally and vertically angular turning the selective directional transceiver toward the target object and moving the hand held component toward the target object shall help the user of the object locator to locate the target object, even it is in a different level of the building with the level which the hand held component is in.
The hand held component may keep a list of identifications of multiple target objects in the memory to locate them one by one. A voice recognition unit and a key stroke recognition unit in the hand held component shall allow the user of the object locator to easily locate the object by voice and/or key stroke.
We may embed the object locater in an existing device like cellular phone set, personal digital assistant, or car alarm remote, to share its hardware, software, memory and display, etc, thus object locating expands the additional application of the existing device.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, this invention provides an object locator to locate a list of target objects. Said object locator is composed of a hand held component, a responding component and an external ID installation device. Said hand held component is moving around, perhaps carried by a person, to locate a target object. Said hand held component consists of a setup unit, a searching unit, a selective directional transceiver with selective directional antenna (hereafter selective directional transceiver), an ID log, a display unit with light and sound functions. Said responding component is carried by or attached to the target object and consists of an omni-directional transceiver with omni-directional antenna (hereafter omni-directional transceiver), a lookup unit, an ID slot, a light unit and a sound unit. Said selective directional transceiver and omni-directional transceiver must work at the same frequency of wireless wave. Said external ID installation device is to write the identification into said ID slot.
Before target object locating can be done, said external ID installation device shall install said identification into said ID slot for the target object. Said external ID installation device can be an independent computer system. Short distance wireless transfer, like infrared wave, or direct connecting between said external ID installation device and said responding component may be used. The identification assignment can be done in the manufacturer's factory. To avoid accidental erasure of said ID slot of its identification, it should be made of a type of read-only memory, like ROM, PROM, EPROM, EEPROM, etc.
Said object locator can be used in a variety of applications. For instance, if the target object is a vehicle, the Vehicle Identification Number (hereafter VIN) of the vehicle can be the identification. The manufacturer of the vehicle or its vendor of said responding component may use said external ID installation device to write the VIN into said ID slot. Using said setup unit in said hand held component, the user of said object locator shall write the identification of the target object into said ID log. Said ID log may keep one or more identifications.
Referring to FIG. 2, this invention provides an object locator to locate a list of target objects. FIG. 2 is same with FIG. 1, except there is no said external ID installation device. And the identification assignment to said ID slot is done by said setup unit. Therefore, there is a two way communication between said setup unit and said selective directional transceiver.
Before target object locating, the identification assignment to said ID slot and said ID log must be done. A password is required to do so. When the password is approved, said setup unit shall assign the identification to the target object as below. Said setup unit shall send the identification of the target object to said selective directional transceiver. Said selective directional transceiver shall format a wireless wave of initial signal with the identification indicating installation process type and emit it to said omni-directional transceiver in said responding component. Upon receiving said wireless wave of initial signal, said omnidirectional transceiver shall extract said identification and said installation process type from it and send them to said lookup unit. Detecting that said initial signal is for installation process, said lookup unit then writes the identification to said ID slot and sends an acknowledge signal to said omni-directional transceiver. Said omni-directional transceiver shall format a wireless wave of acknowledge signal and send it to said selective directional transceiver. Said selective directional transceiver shall extract said acknowledge from said wireless wave of acknowledge signal and send it to said setup unit. Said setup unit then adds the identification to said ID log.
To avoid mistakenly assigning the identification to an undesired target object, the communication between two transceivers for installation may be replaced by direct connection between said hand held component and responding component. Short distance wireless transfer, like infrared wave, may be used.
For both RIG. 1 and FIG. 2, once the identification assignment is done, target object locating can be applied as below.
Said searching unit of hand held component shall choose an identification of the target object from said ID log. And send said identification to said selective directional transceiver for it to format a wireless wave of initial signal with the identification indicating the searching process type, and emit it to said omni-directional transceiver in said responding component. Upon receiving said wireless wave of initial signal, said omni-directional transceiver shall extract said identification with the searching process type from it, and send said identification with the searching process type to said lookup unit.
Upon receiving said identification with the searching process type, said lookup unit then looks up the identification from said ID slot. If the identifications match, said lookup unit shall trigger said light unit and said sound unit. Said light unit shall issue a series of lights, like blinking lights. And said sound unit shall issue a series of sounds. The lights and sounds may depend on the strength of received wireless wave. The stronger the strength, the higher frequency of blinking lights and the louder amplitude of sounds are.
Said lookup unit shall also send an acknowledge signal to said omni-directional transceiver for it to format a wireless wave acknowledge signal and send it to said selective directional transceiver. Upon receiving said wireless wave acknowledge signal, said selective directional transceiver shall extract said acknowledge signal and sent it to said display unit.
If the identification in said ID slot of said responding component was installed by said external ID installation device, said initial signal shall only consist of identification, there is no need to indicate said installation process type or said searching process type.
Upon receiving said acknowledge signal, said display unit shall convert said acknowledge signal to a visible signal indicating its strength. The light and sound shall be more frequent and louder, respectively, for stronger acknowledge signal. Since said selective directional transceiver is direction sensitive, the strength of said acknowledge signal is strongly dependent on the direction of said selective directional transceiver relative to the target object. The user may angularly turn said selective directional transceiver with said hand held component toward the direction of the target object to get the strongest said acknowledge signal. The user then moves or walks in that direction toward the target object. Thus the combination of angular turning said selective directional transceiver with said hand held component and moving toward the target object will help the user to quickly locate the target object.
Once the target object is located, the user shall stop the searching process. Said searching unit may send an ending signal to said responding component through said selective directional transceivers and said omni-directional transceiver to stop said omni-directional transceiver from emitting said wireless wave of acknowledge signal. Also said omni-directional transceiver shall notify said lookup unit to turn off said light unit and said sound unit. To stop the searching process, the user may turn off the display of said display unit. Of course, this will stop its light function and sound function. If said object locater is embedded in a device; such as cellular phone set, personal digital assistant (hereafter PDA), or car alarm remote, the device shall then be used for its other applications.
In the case that said object locator is used to locate only one target object, said ID log is not necessary. Instead said searching unit shall be installed and keep the identification of the target object.
Said object locator may be embedded in an existing device like cellular phone hand set, PDA, or car alarm remote, to share its hardware, software, memory and the display unit, etc. That way, the cellular phone hand set, PDA, or alarm remote user may carry it to locate a target object like a vehicle parked in the parking lot. We may share said selective directional antenna with the antenna of existing device. A wave shield like mesh made of metal can be added to allow said antenna to receive or emit wireless wave in selective direction when used for object locating. And a different working frequency on object locating from the frequency of the exiting applications in cellular phone hand set is desirable.
Angularly turning said selective directional transceiver may be done horizontally or vertically. For instance, the target object may be in different level of the building from the level that the user of said object locator is in. The user may horizontally turn said selective directional transceiver to determine the direction on of the target object, and then vertically turn said selective directional transceiver to determine whether the target object is on the same level or a higher or lower level of the building.
Referring to FIG. 3 and FIG. 4, a voice recognition unit including a voice accept unit (not shown) like microphone to allow the user of the object locator to use voice to locate the object. The user of the object locator may save voice signals corresponding to the identifications of the object in said ID log to said voice recognition unit through said voice accept unit. Then upon receiving one of said voice signals, said voice recognition unit shall pick up the correspondent identification from said ID log and send the identification to said searching unit for locating the object as described above. For instance, if the user saves a voice of “number 3” corresponding to an object to said voice recognize unit, then the user shall only say “number 3” to said voice accept unit to search the object.
FIG. 3 and FIG. 4, also use a key stroke recognition unit including a key pad unit (not shown) to allow the user of the object locator to use key stroke to locate the object. The user of the object locator may save key stroke signals corresponding to the identifications of the object in said ID log to said key stroke recognition unit through said key pad unit. Then, upon receiving one of said key stroke signals, said key stroke recognize unit shall pick up the correspondent identification from said ID log and send the identification to said searching unit for locating the object as described above. For instance if the user saves a key stroke signal of “5” corresponding to an object to said key stroke recognize unit, then the user shall only strike key “5”, probably followed by a“#” on said key pad unit for searching the object.
