This invention relates generally to mobile telephones and more specifically to a mobile telephone with integrated distance measurement functionality.
Wireless mobile telephones provide communications such as internet access and email capabilities in addition to 2-way voice communications. An additional function on some mobile telephones is a camera.
Standalone measuring devices such as a laser based linear measurement device are available. While such devices can provide accurate measurement readings, it is often inconvenient to record, store, and/or keep track of such readings, especially where a large number of measurements are to be made. For example, determining the interior square footage of a house having several rooms requires a series of linear measurements that must be manually recorded in pairs in order to later calculate the square footage of each room. There exists a need for an integrated apparatus and method that can provide 2-way communications as well as conveniently record, store and keep track of linear distance measurements
It is an object of the present invention to satisfy this need.
An exemplary embodiment of a wireless mobile telephone includes a transmitter and receiver module for transmitting and receiving radio frequency communications, and a display screen. A mechanism acquires linear distance measurements to objects within line of sight of the wireless mobile telephone. A graphical representation of a structure having elements to be measured is stored in memory. A microprocessing unit operating under the control of software stores in the memory a plurality of the linear distance measurements, where each stored linear distance measurement is associated with a corresponding element of the graphical representation as shown on the display screen. This enables areas defined by a pair of such elements to be calculated.
An exemplary method makes distance measurements utilizing a wireless mobile telephone. A graphical representation of a structure having elements to be measured is stored in memory of the wireless mobile telephone and displayed on a screen of the wireless mobile telephone. Linear distance measurements to objects within line of sight of the wireless mobile telephone are acquired and stored in the memory together with an association with one of a selected element of the graphical representation as shown on the display screen.
Features of exemplary implementations of the invention will become apparent from the description, the claims, and the accompanying drawings in which:
Referring to
In the second system, a second subscriber utilizes a wireless device 24 that supports broadband wireless capabilities and preferably includes a browser for interfacing with internet communications, e.g. TCP/IP transmissions. A radio access network (RAN) 26 supports communications between the device 24 and packet data network equipment (PDNE) 28. The PDNE supports communications between the RAN 26 and the PSTN and internet of network 23. The specific equipment that makes up the PDNE varies depending on the communications technology/format utilized, e.g.:
for HRPD (High Rate Packet Data—a high-speed CDMA-based wireless data technology): a PCF (Packet Control Function) device, a PDSN (Packet Data Service Node) device, Foreign and Home Agent devices, and an AAA server.
for GPRS (General Packet Radio Service): a SGSN (Serving GPRS Support Node) device, a GGSN (Gateway GPRS Support Node) device, VLR and HLR devices.
for CDMA (Code Division Multiple Access) IS-95: IWF (Interworking Function) device and an AAA server.
The first and second systems are connected by the internet of network 23 to a host site 30 having an associated database 32. The host site 30 provides an interface for wireless subscribers such as using devices 10 and 24 to a variety of templates stored in database 32. The templates provide a framework that assists the subscribers in collecting and storing linear measurements made by the subscriber as will be explained in more detail below.
The exemplary mobile handset devices 10 and 24 each include the capability of making linear measurements such as by a laser measurement device. As used herein, a linear measurement means the measurement of a distance as determined along a straight line from the mobile telephone handset or a local device coupled to the handset to an object without the assistance of external information such as global positioning satellite information or similar information. The laser measurement device can be contained within the housing of the handset, as in the illustrative device 24. The laser measurement device emits a laser beam from port 40, receives reflections, and has separate measurements controlled by the depression of a button 42. Alternatively, a laser measurement device 50 is housed separate from the handset 10 and is coupled to the handset by a cable 52 (or Bluetooth local wireless connection, Infrared, etc.). The laser measurement device 50 emits a laser beam from port 54, receives beam reflections, and has separate measurements controlled by the depression of a button 56. In both handsets 10 and 24, the measurement readings are coupled to the handset and stored in memory. In a further enhanced functionality, the measurement readings are associated with a measurement template that has been previously downloaded into the handset from database 32. The collected measurements stored in memory of the handset can then be transmitted as an SMS message, email or data to another device or site. This will be explained in more detail below.
In step 104 the subscriber activates the measurement program in mobile handset 24 and loads the selected template. In a preferred embodiment a visual representation of the geometry associated with the selected template is displayed on the screen of the mobile handset. In step 106 the subscriber selects one element of the template to be measured such as by using a graphical user interface to select one element as displayed on the screen of the handset, e.g. the subscriber selects a wall associated with a room to be measured. In step 104 the subscriber, after positioning the mobile handset at a location and in a direction so as to measure the length of the selected wall, presses button 42 causing the laser measurement unit to measure the length of the selected wall. This measurement representing the length of the wall, such as measured in feet, is stored in the mobile handset in association with the identified wall. For example, a record may be used to store the measurement and a label identifying the wall that was measured. In step 110 a determination is made of whether more measurements are to be made. This determination may be manually made by the subscriber. Alternatively, the measurement program may automatically make this determination based on whether measurements have been made of all elements that comprise the selected template. A YES determination by step 110 results in further measurements being made for selected elements of the template as indicated by a return to step 106. A NO determination by step 110 results in the stored measurement records being transmitted to an external storage device, e.g. database 32 in accordance with step 112. In step 114 the areas and/or volumes are calculated for each segment of the template based on the measurements associated with each segment. Alternatively, the mobile handset itself may be used to implement step 114 assuming the handset has sufficient memory storage and computational capabilities. This method terminates at END step 116.
The exemplary handset in one example employs one or more computer-readable signal-bearing tangible media. The computer-readable signal-bearing media store software, firmware and/or assembly language for performing one or more portions of one or more embodiments of the invention. The computer-readable signal-bearing medium may comprise one or more of a magnetic, electrical, optical, biological, and atomic data storage tangible medium. For example, the computer-readable signal-bearing medium comprise floppy disks, magnetic tapes, CD-ROMs, DVD-ROMs, hard disk drives, flash memory, PROM, and electronic memory.
Although exemplary implementations of the invention have been depicted and described in detail herein, it will be apparent to those skilled in the art that various modifications, additions, substitutions, and the like can be made without departing from the spirit of the invention. For example, steps in the method can be omitted, performed in a different order, and/or performed by other devices. Distance measurements can be made by using other energy types, e.g. acoustic, infrared, etc. Elements to be measured can be identified by indicia or labels in a table instead of in a graphical representation. A measurement can be made before a corresponding element has been selected, and then the measurement associated with a selected element. Potential users of such a device include realtors, contractors, landscapers, interior designers and building inspectors.
